FINANCE ACT, 1959

Provided that in applying the provisions of subsection (4) of section 34 of this Act to any such balancing charge, the deductions and allowances allowed or made in respect of the machinery or plant for the year beginning on the 6th day of April, 1959, or for any earlier year of assessment shall not be taken to include deductions or allowances made to, or attributable to the shares of, persons who were not, either alone or in partnership with other persons, carrying on the trade at the beginning of the year beginning on the 6th day of April, 1959.

• (2) In charging the profits or gains of a trade carried on in partnership, the same allowances, deductions and charges shall be allowed or made in respect of machinery or plant used for the purposes of that trade and belonging to one or more of the partners but not being partnership property as would fall to be allowed or made if the machinery or plant had at all material times belonged to all the partners and been partnership property and everything done by or to any of the partners in relation thereto had been done by or to all the partners.

• (3) Notwithstanding anything in section 34 of this Act, a sale or gift of machinery or plant used for the purposes of a trade carried on in partnership, being a sale or gift by one or more of the partners to one or more of the partners, shall not be treated as an event giving rise to a balancing allowance or a balancing charge if the machinery or plant continues to be used after the sale or gift for the purposes of that trade.

• (4) References in subsections (2) and (3) of this section to use for the purposes of a trade do not include references to use in pursuance of a letting by the partner or partners in question to the partnership or to use in consideration of the making to the partner or partners in question of any payment which may be deducted in computing the profits or gains of the trade.

38 Machinery or plant used partly for non-trading purposes.

38.—Where an event occurs which gives rise or might give rise to a balancing allowance or balancing charge to or on any person and the machinery or plant concerned is machinery or plant which has been used by that person for the purposes of a trade carried on by him and has also been used for other purposes, then, in determining the amount of the allowance, or, as the case may be, the amount on which the charge is to be made, regard shall be had to all the relevant circumstances and, in particular, to the extent of the use for the said other purposes, and there shall be made to or on him an allowance of such an amount, or, as the case may be, a charge on such an amount, as may be just and reasonable.

39 Calculation of balancing allowances and balancing charge in certain cases.

39.—(1) Where an event occurs which gives rise or might give rise to a balancing allowance or balancing charge in respect of machinery or plant, the event is the permanent discontinuance of a trade, and at or about the time of the discontinuance there occurs in relation to the machinery or plant any event such as is mentioned in paragraphs (a) to (c) of the definition of “sale, insurance, salvage or compensation moneys” in section 67 of this Act, not being a sale at less than open-market price other than a sale to which section 62 of this Act applies, then, for the purpose of determining—

• (a) whether the discontinuance gives rise to a balancing allowance or balancing charge, and, if so,

• (b) the amount of the allowance or, as the case may be, the amount on which the charge is to be made,

the amount of the net proceeds, compensation, receipts or insurance moneys mentioned in the said paragraphs (a) to (c) which arise on the last-mentioned event shall be deemed to be an amount of sale, insurance, salvage or compensation moneys arising on the permanent discontinuance of the trade.

• (2)
• (i) Subject to subsections (3) and (5) of this section, paragraph (ii) of this subsection shall have effect where an event occurs which gives rise or might give rise to a balancing allowance or balancing charge in respect of machinery or plant, and either—

• (a) the event is the permanent discontinuance of the trade and immediately after the time of the discontinuance the machinery or plant continues to belong to the person by whom the trade was carried on immediately before the said time and the case is one not falling within subsection (1) of this section,

• (b) the event is the permanent discontinuance of the trade and at the time of the discontinuance the machinery or plant is either sold at less than the open-market price, the sale not being one to which section 62 of this Act applies, or the machinery or plant is given away,

• (c) the event is the sale of the machinery or plant at less than the open-market price, not being a sale to which the said section 62 applies, or is the gift of the machinery or plant, or

• (d) the event is that, after the setting up and before the permanent discontinuance of the trade, the machinery or plant permanently ceases to be used for the purposes of a trade carried on by the person by whom the first-mentioned trade is being carried on, and so ceases either by reason of that person's transferring the machinery or plant to other use or, on a transfer of the trade which is not treated as involving a discontinuance thereof, by reason of the retention of the machinery or plant by the transferor.

• (ii) For the purpose of determining whether a balancing allowance or balancing charge falls to be made and, if so, the amount of the allowance or, as the case may be, the amount on which the charge is to be made, the event shall be treated as if it had given rise to sale, insurance, salvage or compensation moneys of an amount equal to the open-market price of the machinery or plant.

• (3) References in subsection (2) of this section to the sale of machinery or plant at less than the open-market price do not include references to the sale thereof in such circumstances that there is a charge to income tax under Schedule E by virtue of the provisions of Part IV of Finance Act, 1958, and paragraph (ii) of that subsection shall not apply by reason of the gift of machinery or plant if the machinery or plant is given away in such circumstances as aforesaid.

• (4) Subject to the provisions of subsection (5) of this section, where paragraph (ii) of subsection (2) of this section has effect by reason of the gift or sale of machinery or plant to any person, and that person receives or purchases it with a view to using it for the purposes of a trade carried on by him, then, in determining whether any, and if so what, wear and tear allowances, balancing allowances or balancing charges are to be made in connection with that trade the like consequences shall ensue as if the recipient or purchaser had purchased the machinery or plant at the open-market price.

• (5) Where, in a case falling within subsection (4) of this section, the recipient or purchaser and the donor or seller by notice in writing to the inspector of taxes jointly so elect the following provisions shall have effect:

• (a) paragraph (ii) of subsection (2) and subsection (4) of this section shall have effect as if for the references to the open-market price there were substituted references to that price or the amount of the expenditure on the provision of the machinery or plant still unallowed immediately before the gift or sale, whichever is the lower;

• (b) notwithstanding anything in this Chapter, such balancing charge, if any, shall be made on the recipient or purchaser on any event occurring after the date of the gift or sale as would have fallen to be made on the donor or seller if the donor or seller had continued to own the machinery or plant and had done all such things and been allowed all such allowances in connection therewith as were done by or allowed to the recipient or purchaser.

• (6) In this section “open-market price”, in relation to any machinery or plant, means the price which the machinery or plant would have fetched if sold in the open market at the time of the event in question.

40 Option in cas6 of succession under will or intestacy.

40.—Where a person succeeds to a trade as a beneficiary under the will or on the intestacy of a deceased person who carried on that trade, the following provisions shall, if the beneficiary by notice in writing to the inspector of taxes so elects, have effect in relation to any machinery or plant previously owned by the deceased person and used by him for the purposes thereof:

• (a) the reference in section 63 of this Act to the price which the machinery or plant would have fetched if sold in the open market shall, in relation to the succession and any previous succession occurring on or after the death of the deceased, be deemed to be a reference to that price or the amount of the expenditure on the provision of the machinery or plant still unallowed immediately before the succession in question, whichever is the lower; and

• (b) notwithstanding anything in that section, such balancing charge, if any, shall be made on the beneficiary on any event occurring after his succession as would have fallen to be made on the deceased if he had not died and had continued to own the machinery or plant and had done all such things and been allowed all such allowances in connection therewith as were done by or allowed to the beneficiary or the successor on any such previous succession as is mentioned in paragraph (a) of this section.

41 Wear and tear allowance to be deemed to have been made in certain cases.

41.—(1) In determining whether any, and if so what, balancing allowance or balancing charge falls to be made to or on any person for any year of assessment in charging the profits or gains of a trade, there shall be deemed to have been made to that person, for every previous year of assessment in which the machinery or plant belonged to him and which is a year of assessment to be taken into account for the purpose of this section, such wear and tear allowance or greater wear and tear allowance, if any, in respect of the machinery or plant as would have fallen to be made to him if all the conditions specified in subsection (3) of this section had been fulfilled in relation to every such previous year.

• (2) There shall be taken into account for the purposes of this section every previous year of assessment in which the machinery or plant belonged to the person and—

• (a) during which the machinery or plant was not used by the person for the purposes of the trade,

• (b) during which the trade was not carried on by him,

• (c) during which the trade was carried on by him in such circumstances that, otherwise than by virtue of Part II of Finance (Miscellaneous Provisions) Act, 1958, the full amount of the profits or gains thereof was not liable to be charged to income tax,

• (d) for which the whole or a part of the income tax chargeable in respect of the profits of the trade was not payable by virtue of Finance (Profits of Certain Mines) (Temporary Relief from Taxation) Act, 1956, or

• (e) for which the income tax payable in respect of the profits of the trade was reduced by virtue of Part II or III of Finance (Miscellaneous Provisions) Act, 1956.

• (3) The conditions referred to in subsection (1) of this section are:

• (a) that the trade had been carried on by the person in question ever since the date on which he acquired the machinery or plant and had been so carried on by him in such circumstances that the full amount of the profits or gains thereof was liable to be charged to income tax,

• (b) that the trade had at no time consisted wholly or partly of exempted trading operations within the meaning of Finance (Miscellaneous Provisions) Act, 1958,

• (c) that the machinery or plant had been used by him solely for the purposes of the trade ever since that date, and

• (d) that a proper claim had been duly made by him for wear and tear allowance in respect of the machinery or plant for every relevant year of assessment.

• (4) Nothing in this section shall affect the provisions of subsection (4) of section 34 of this Act.

42 Subsidies towards wear and tear.

42.—(1) Where—

• (a) an event occurs which gives rise or might give rise to a balancing allowance or balancing charge to or on any person in respect of any machinery or plant provided or used by him for the purposes of a trade; and

• (b) any sums (hereinafter in this section referred to as the said sums) which—

• (i) are in respect of, or take account of, the wear and tear to the machinery or plant occasioned by its use for the purposes of the trade, and

• (ii) do not fall to be taken into account as his income or in computing the profits or gains of any trade carried on by him,

have been paid, or are or are to be payable, to him directly or indirectly,

then, in determining whether and, if so what, balancing allowance or balancing charge falls to be made to or on that person, there shall be deemed to have been made to him for the years of assessment during which the machinery or plant was used for the purposes of the trade wear and tear allowances in respect thereof the total amount of which is equal to the total amount of the said sums, over and above the wear and tear allowances, if any, which have been made to him in respect of the machinery or plant.

• (2) Nothing in this section shall affect the provisions of subsection (4) of section 34 of this Act.

43 Application to lessors.

43.—(1) Where machinery or plant is let upon such terms that the burden of the wear and tear thereof falls directly upon the lessor, the preceding provisions of this Chapter shall apply in relation to the lessor as if the machinery or plant were, during the term of the letting, in use for the purposes of a trade carried on by him.

• (2) For paragraph (5) of Rule 6 of the Rules applicable to Cases I and II of Schedule D there shall be substituted the following paragraph:—

• “(5) Where machinery or plant is let upon such terms that the burden of the wear and tear thereof falls directly on the lessor, he shall be entitled, on making a claim to the inspector of taxes within twelve months after the end of the year of assessment, to an allowance on account of the wear and tear of the machinery or plant equal to the amount which might have been allowed if, during the period of the letting, the machinery or plant were in use for the purposes of a trade carried on by him.”,

and references to the said paragraph (5) in any Act passed before the commencement of this Part of this Act shall be construed as references to the paragraph substituted by this subsection.

44 Manner of making allowances and charges (machinery and plant).

44.—(1) Any balancing allowance or balancing charge made to or on any person under the preceding provisions of this Chapter shall, unless it is made under or by virtue of section 43 of this Act, be made to or on that person in charging the profits or gains of his trade.

• (2) Any wear and tear allowance or balancing allowance made under or by virtue of section 43 of this Act shall be made by way of discharge or repayment of tax and shall be available primarily against income from the letting of machinery or plant.

• (3) Any balancing charge made under or by virtue of section 43 of this Act shall be made under Case VI of Schedule D.

45 Application to professions, etc., and exception as respects lands.

45.—(1) The preceding provisions of this Chapter shall, with any necessary adaptations, apply in relation to professions, employments, vocations and offices, as they apply in relation to trades.

Chapter III. Patents.

46 Interpretation (Chapter III of Part V).

46.—(1) In this Chapter—

“income from patents” means—

• (a) any royalty or other sum paid in respect of the user of a patent, and

• (b) any amount on which tax is payable for any year of assessment by virtue of any of the provisions of this Chapter;

“the commencement of the patent” means, in relation to a patent, the date as from which the patent rights become effective;

“patent rights” means the right to do or authorise the doing of anything which would, but for that right, be an infringement of a patent;

“Irish patent” means a patent granted under the laws of the State;

“the operative date” means the date of the commencement of this Part of this Act.

• (2) In this Chapter, any reference to the sale of part of patent rights includes a reference to the grant of a licence in respect of the patent in question, and any reference to the purchase of patent rights includes a reference to the acquisition of a licence in respect of a patent:

Provided that if a licence granted by a person entitled to any patent rights is a licence to exercise those rights to the exclusion of the grantor and all other persons for the whole of the remainder of the term for which the rights subsist, the grantor shall be treated for the purposes of this Chapter as thereby selling the whole of the rights.

• (3) Where, under section 130 of the Industrial and Commercial Property (Protection) Act, 1927, or any corresponding provisions of the law of any country outside the State, an invention which is the subject of a patent is made, used, or exercised or vended by or for the service of the State or the government of the country concerned, the provisions of this Chapter shall have effect as if the making, user, exercise or vending of the invention had taken place in pursuance of a licence, and any sums paid in respect thereof shall be treated accordingly.

• (4) Any reference in this Chapter to the number of years comprised in a period shall be construed as a reference to the number of consecutive periods of twelve months, beginning with the day with which the period begins, which are comprised in the period, any odd period being treated as a complete twelve months:

Provided that nothing in this subsection shall be construed as affecting any reference in this Chapter to the number of complete years comprised in any period or which have elapsed since any date.

47 Annual allowances for capital expenditure on purchase of patent rights.

47.—(1) Where, on or after the operative date, a person incurs capital expenditure on the purchase of patent rights, there shall, subject to and in accordance with the following provisions of this Chapter, be made to him for each of the relevant years of assessment, as hereinafter denned, an allowance (in this Chapter referred to as an annual allowance) equal to the appropriate fraction, as hereinafter denned, of the amount of that expenditure:

Provided that no annual allowance shall be made to a person in respect of any expenditure unless—

• (a) the allowance falls to be made to him in charging the profits or gains of his trade, or

• (b) any income receivable by him in respect of the rights would be liable to income tax.

• (2) The relevant years of assessment are, in the case of any person, the seventeen years of assessment beginning with the year of assessment in his basis period for which the expenditure was incurred:

Provided that—

• (a) where the rights are purchased for a specified period, the preceding provisions of this subsection shall have effect with the substitution for the reference to seventeen years of a reference to seventeen years or the number of years comprised within that period, whichever is the less,

• (b) where the rights purchased begin one complete year or more after the commencement of the patent and paragraph (a) of this proviso does not apply, the said-provisions shall have effect with the substitution for the reference to seventeen years of a reference to seventeen years less the number of complete years which, when the rights begin, have elapsed since the commencement of the patent, or, if seventeen complete years have elapsed as aforesaid, of a reference to one year, and

• (c) any expenditure incurred on or after the operative date for the purposes of a trade by a person about to carry it on shall be treated for the purposes of this subsection as if it had been incurred by that person on the first day on which he does carry it on, unless, before the said first day, he has sold all the rights on the purchase of which the expenditure was incurred.

• (3) The appropriate fraction is the fraction the numerator of which is one and the denominator of which is the number of the relevant years of assessment.

48 Effect of lapse of patent rights, sales, etc.

48.—(1) Where, on or after the operative date, a person incurs capital expenditure on the purchase of patent rights and, before the end of the relevant years of assessment, any of the following events occurs:

• (a) the rights come to an end without being subsequently revived;

• (b) he sells all those rights or so much thereof as he still owns;

• (c) he sells part of those rights and the net proceeds of the sale (so far as they consist of capital sums) are not less than the amount of the capital expenditure remaining unallowed;

no annual allowance shall be made to that person for the year of assessment in his basis period for which the event takes place or any subsequent year of assessment.

• (2) Where, on or after the operative date, a person incurs capital expenditure on the purchase of patent rights and, before the end of the relevant years of assessment, either of the following events occurs:

• (a) the rights come to an end without being subsequently revived;

• (b) he sells all those rights, or so much thereof as he still owns, and the net proceeds of the sale (so far as they consist of capital sums) are less than the amount of the capital expenditure remaining unallowed;

there shall, subject to and in accordance with the following provisions of this Chapter, be made to him for the year of assessment, in his basis period for which the event takes place, an allowance (in this Chapter referred to as a balancing allowance) equal, if the event is the rights coming to an end, to the amount of the capital expenditure remaining unallowed, and, if the event is a sale, to the amount of the capital expenditure remaining unallowed less the net proceeds of the sale.

• (3) Where a person who, on or after the operative date, has incurred capital expenditure on the purchase of patent rights sells all or any part of those rights and the net proceeds of the sale (so far as they consist of capital sums) exceed the amount of the capital expenditure remaining unallowed, if any, there shall, subject to and in accordance with the following provisions of this Chapter, be made on him for the year of assessment, in his basis period for which the sale takes place, a charge (in this Chapter referred to as a balancing charge) on an amount equal to the excess or, where the amount of the capital expenditure remaining unallowed is nil, to the said net proceeds.

• (4) Where a person who, on or after the operative date, has incurred capital expenditure on the purchase of patent rights sells a part of those rights and subsection (3) of this section does not apply, the amount of any annual allowance made in respect of that expenditure for the year of assessment in his basis period for which the sale takes place or any subsequent year of assessment shall be the amount arrived at by—

• (a) subtracting the net proceeds of the sale (so far as they consist of capital sums) from the amount of the expenditure remaining unallowed at the time of the sale, and

• (b) dividing the result by the number of the relevant years of assessment which remained at the beginning of the year of assessment in his basis period for which the sale takes place,

and so on for any subsequent sales.

• (5) References in the preceding provisions of this section to the amount of any capital expenditure remaining unallowed shall, in relation to any event, be construed as references to the amount of that expenditure less any annual allowances made in respect thereof for years of assessment before the year of assessment in the basis period for which that event occurs, and less also the net proceeds of any previous sale by the person who incurred the expenditure of any part of the rights acquired by the expenditure, so far as those proceeds consist of capital sums.

• (6) Notwithstanding anything in the preceding provisions of this section, no balancing allowance shall be made in respect of any expenditure unless an annual allowance has been, or, but for the happening of the event giving rise to the balancing allowance, could have been, made in respect of that expenditure, and the total amount on which a balancing charge is made in respect of any expenditure shall not exceed the total annual allowances actually made in respect of that expenditure, less, if a balancing charge has previously been made in respect of that expenditure, the amount on which that charge was made.

49 Special provision for certain capital expenditure.

49.—Where within one year before the operative date a person has incurred capital expenditure on the purchase of patent rights for the purposes of a trade carried on or about to be carried on by him and has not sold any part of the said rights before the operative date, he shall be deemed for the purposes of sections 47 and 48 of this Act to have incurred the said expenditure on the operative date.

50 Charges on capital sums received for sale of patent rights.

50.—(1) Where, on or after the operative date, a person resident in the State sells any patent rights and the net proceeds of the sale consist wholly or partly of a capital sum, he shall, subject to the provisions of this Chapter, be charged to tax under Case VI of Schedule D, for the year of assessment in which the sum is received by him and for each of the five succeeding years of assessment, on an amount equal to one-sixth of that sum:

Provided that—

• (a) if that person, by notice in writing served on the inspector of taxes not later than twelve months after the end of the year of assessment in which that sum was received, elects that the whole of that sum shall be charged to tax for the said year of assessment, it shall be charged to tax accordingly;

• (b) if that person, by notice as aforesaid, applies to have the period for which he is to be charged determined as being other than the six years of assessment hereinbefore referred to (that is to say, the year of assessment in which that sum was received and the five succeeding years of assessment), then, if it appears to the Revenue Commissioners that hardship is likely to arise having regard to all the circumstances of the case unless a direction is given under this paragraph, they may direct that the charge shall be spread equally over a number of years of assessment other than six, of which the first shall be the year of assessment in which that sum was received.

• (2) Where, on or after the operative date, a person not resident in the State sells any patent rights and the net proceeds of the sale consist wholly or partly of a capital sum, and the patent is an Irish patent, then, subject to the provisions of this Chapter—

• (a) he shall be chargeable to tax in respect of that sum under Case VI of Schedule D, and

• (b) Rule 21 of the General Rules shall apply to that sum as if it were an annual payment payable otherwise than out of profits or gains brought into charge to tax:

Provided that if, not later than twelve months after the end of the year of assessment in which the sum is paid, the person to whom it is paid, by notice in writing to the Revenue Commissioners, elects that the said sum shall be treated for the purpose of income tax for that year and for each of the five succeeding years as if one-sixth thereof, and no more, were included in his income chargeable to tax for all those years respectively, it shall be so treated, and all such repayments and assessments of tax for each of those years shall be made as are necessary to give effect to the election, so, however, that—

• (i) the election shall not affect the amount of tax falling to be deducted and accounted for under the said Rule 21,

• (ii) where any sum is deducted under the said Rule 21, any adjustments necessary to give effect to the election shall be made by way of repayment of tax, and

• (iii) the said adjustments shall be made year by year and as if one-sixth of the sum deducted had been deducted in respect of tax for each year, and no repayment of, or of any part of, that portion of the tax deducted which is to be treated as deducted in respect of tax for any year shall be made unless and until it is ascertained tha the tax (other than sur-tax) ultimately falling to be paid for that year is less than the amount of tax (other than sur-tax) paid for that year.

• (3) Where the patent rights sold by a person, or the rights out of which the patent rights sold by a person were granted, were acquired by him by purchase and the price paid consisted wholly or partly of a capital sum, subsections (1) and (2) of this section shall apply as if any capital sum received by him when he sells the rights were reduced by the amount of that sum:

Provided that—

• (a) where between the said purchase and the said sale he has sold part of the patent rights acquired by him and the net proceeds of that sale consist wholly or partly of a capital sum, the amount of the reduction falling to be made under this subsection in respect of the subsequent sale shall be itself reduced by the amount of that sum,

• (b) nothing in this subsection shall effect the amount of tax falling to be deducted and accounted for under Rule 21 of the General Rules by virtue of subsection (2) of this section, and, where any sum is deducted under the said Rule 21, any adjustment necessary to give effect to the provisions of this subsection shall be made by way of repayment of tax.

• (4) This section shall apply in relation to any sale of part of any patent rights as it applies in relation to sales of patent rights.

51 Patent rights sold before the operative date.

51.—Nothing in the preceding provisions of this Chapter shall apply in relation to any patent rights if those rights, or any rights out of which they were granted, have been the subject of a sale before the operative date and the proceeds of the sale consisted wholly or partly of a capital sum:

Provided that, in relation to any patent rights to which section 49 of this Act applies, this section shall apply as if, for the reference to the operative date, there were substituted a reference to the date on which the said rights were purchased by the person who, by virtue of that section, is deemed to have purchased them on the operative date.

52 Relief for expense.

52.—(1) In computing the profits or gains of any trade, there shall be allowed to be deducted as expenses any fees paid or expenses incurred on or after the operative date in obtaining, for the purposes of the trade, the grant of a patent or an extension of the term of a patent.

• (2) Where—

• (a) on or after the operative date, a person, otherwise than for the purposes of a trade carried on by him, pays any fees or incurs any expenses in connection with the grant or maintenance of a patent or the obtaining of an extension of a term of a patent, and

• (b) those fees or expenses would, if they had been paid or incurred for the purposes of a trade, have been allowable as a deduction in estimating the profits or gains thereof,

there shall be made to him, for the year of assessment in which those expenses were paid or incurred, an allowance equal to the amount thereof.

• (3) Where a patent is granted in respect of any invention, an allowance equal to so much of the net amount of any expenses incurred on or after the operative date by an individual who, whether alone or in conjunction with any other person, actually devised the invention as is properly ascribable to the devising thereof (not being expenses in respect of which, or of assets representing which, an allowance falls to be made under any other provision of the Income Tax Acts) shall be made to that individual for the year of assessment in which the expenses were incurred.

• (4) The provisions of subsection (3) of this section shall apply in relation to expenses incurred before the operative date as if those expenses were incurred on that day, subject to the modification that, if the patent in question was granted one complete year or more before that day, the amount to be allowed shall be reduced by applying thereto the fraction the numerator of which is seventeen less the number of complete years comprised in the period beginning with the commencement of the patent and ending immediately before the operative date and the denominator of which is seventeen.

53 Patent income to be earned income in certain cases.

53.—In considering, in relation to the year of assessment beginning on the operative date or any subsequent year of assessment, whether any, and if so what, relief is to be granted to an individual under section 16 of the Finance Act, 1920, or under subsection (2) of section 18 of that Act, any income from patent rights arising to an individual shall, where the patent was granted for an invention actually devised by him, whether alone or jointly with any other person, be deemed to be earned income:

Provided that where any part of the rights in question or of any rights out of which they were granted has at any time belonged to any other person, so much only of the said income shall be deemed to be earned income as is not properly attributable to the rights which have belonged to that other person.

54 Spreading of income payments over several years.

54.—(1) Where a royalty or other sum to which Rule 19 or Rule 21 of the General Rules applies is paid in respect of the user of a patent, and that user extended over a period of six complete years or more, the person receiving the payment may require that the income tax (including sur-tax) payable by him by reason of the receipt of that sum shall be reduced so as not to exceed the total amount of income tax (including sur-tax) which would have been payable by him if that royalty or sum had been paid in six equal instalments at yearly intervals, the last of which was paid on the date on which the payment was in fact made.

• (2) Subsection (1) of this section shall apply in relation to a royalty or other sum where the period of the user is two complete years or more but less than six complete years as it applies to the royalties and sums mentioned in that subsection, but with the substitution for the reference to six equal instalments of a reference to so many equal instalments as there are complete years comprised in that period.

• (3) In this section, any reference to the income tax (including sur-tax) payable by a person includes, in cases where the income of a wife is deemed to be the income of the husband, references to the income tax (including sur-tax) payable by his wife or her husband, as the case may be.

• (4) Nothing in this section shall apply to any sum to which Rule 21 of the General Rules applies by virtue of section 50 of this Act.

55 Manner of making allowances and charges (patents).

55.—(1) An allowance or charge under any of the provisions of this Chapter shall be made to or on a person in charging the profits or gains of his trade if—

• (a) he is carrying on a trade the profits or gains of which are, or, if there were any, would be, chargeable to tax under Case I of Schedule D for the year of assessment for which the allowance or charge is made, and

• (b) at any time in his basis period for that year of assessment, the patent rights in question, or other rights out of which they were granted, were or were to be used for the purposes of that trade:

Provided that nothing in this subsection shall affect any of the preceding provisions of this Chapter allowing a deduction as expenses in computing the profits or gains of a trade or requiring a charge to be made under Case VI of Schedule D.

• (2) Save as aforesaid, an allowance under this Chapter shall be made by way of discharge or repayment of tax and shall be available against income from patents, and a charge under this Chapter shall be made under Case VI of Schedule D.

56 Effect of deaths, windings up and partnership changes on charges.

56.—(1) Where a person on whom, by reason of the receipt of a capital sum, a charge falls or would otherwise fall to be made under section 50 of this Act dies or, being a body corporate, commences to be wound up—

• (a) no sums shall be charged under that section on that person for any year of assessment subsequent to that in which the death takes place or the winding up commences, and

• (b) the amount falling to be charged for the year of assessment in which the death occurs or the winding up commences shall be increased by the total amounts which, but for the death or winding up, would have fallen to be charged for subsequent years:

Provided that, in the case of a death, the personal representatives may, by notice in writing served on the inspector of taxes not later than twenty-one days after notice has been served on them of the charge falling to be made by virtue of this section, require that the income tax (including sur-tax) payable out of the estate of the deceased by reason of the increase provided for by this section shall be reduced so as not to exceed the total amount of income tax (including sur-tax) which would have been payable by him or out of his estate by reason of the operation of the said section 50 in relation to that sum, if, instead of the amount falling to be charged for the year in which the death occurs being increased by the whole amount of the sums charged for subsequent years, the several amounts falling to be charged for the years beginning with that in which the capital sum was received and ending with that in which the death occurred had each been increased by the said whole amount divided by the number of those years.

• (2) Where, under the provisions of Chapter V of this Part of this Act, a charge under section 50 of this Act falls to be made on two or more persons jointly as being the persons for the time being parrying on a trade, and that trade is discontinued, the provisions of subsection (1) of this section shall have effect in relation to the discontinuance as they have effect where a body corporate commences to be wound up:

Provided that-—

• (a) the additional sum which, under the said subsection, falls to be charged for the year in which the discontinuance occurs shall be apportioned among the members of the partnership immediately before the discontinuance according to their respective interests in the partnership profits before the discontinuance, and each partner (or, if he is dead, his personal representatives) charged separately for his proportion, and

• (b) each partner (or, if he is dead, his personal representatives) shall have the same right to require a reduction of the total income tax (including sur-tax) payable by him or out of his estate by reason of the increase as would have been exercisable by the personal representatives under the said subsection (1) in the case of a death, and the proviso to that subsection shall have effect accordingly, but as if references to the amount of income tax (including sur-tax) which would have been payable by the deceased or out of his estate in the event therein mentioned were a reference to the amount of income tax (including sur-tax) which would in that event have fallen to be paid or borne by the partner in question or out of his estate.

• (3) In this section, any references to the income tax (including sur-tax) paid or borne or payable or falling to be paid or borne by a person include, in cases where the income of a wife is deemed to be income of the husband, references to the income tax (including sur-tax) paid or borne, or payable or falling to be paid or borne, by his wife or her husband, as the case may be.

Chapter IV. Allowances for Expenditure on Dredging.

57 Allowances for expenditure on dredging.

57.—(1) Subject to the provisions of this section, where a person for the purposes of any qualifying trade carried on by him incurs on or after the 30th day of September, 1956, capital expenditure on dredging, and either the trade consists of the maintenance or improvement of the navigation of a harbour, estuary or waterway or the dredging is for the benefit of vessels coming to, leaving or using any dock or other premises occupied by him for the purposes of the trade, then, there shall be made in respect of the expenditure to the person for the time being carrying on the trade—

• (a) for the first relevant year of assessment, an initial allowance equal to one-tenth of the expenditure, and

• (b) for that and each subsequent year of assessment (until the allowances made under this section in respect of the expenditure equal the amount of the expenditure), an annual allowance equal to one-fiftieth of the expenditure.

• (2) If the trade is permanently discontinued in any year of assessment, then, for that year there shall be made to the person last carrying on the trade, in addition to any other allowance made to him, an allowance equal to the amount of the expenditure less the allowances made in respect of it under subsection (1) of this section for that and previous years of assessment.

• (3) For the purposes of this section, a trade shall not be treated by virtue of Rule 11 of the Rules applicable to Cases I and II of Schedule D as discontinued on a change in the persons engaged in carrying it on.

• (4) Any allowance under this section shall be made in charging the profits or gains of the trade, and if different persons are charged in respect of the trade for different parts of any year of assessment, any annual allowance for that year shall be apportioned between them in proportion to the length of the periods for which they are so charged, but, if it is the first relevant year of assessment, any initial allowance shall be made to the person first carrying on the trade in the year.

• (5) Where expenditure is incurred partly for the purposes of a qualifying trade and partly for other purposes, subsection (1) of this section shall apply to so much only of that expenditure as on a just apportionment ought fairly to be treated as incurred for the purposes of that trade.

• (6) In this section “qualifying trade” means any trade or undertaking which, or a part of which, complies with any of the following conditions:

• (a) the condition that it consists of the maintenance or improvement of the navigation of a harbour, estuary or waterway,

• (b) any condition set out in the provisions of subsection (1) of section 17 of Finance (Miscellaneous Provisions) Act, 1956,

but where part only of a trade or undertaking complies with those conditions, subsection (5) of this section shall apply as if the part which does and the part which does not comply were separate trades.

• (7) Where a person incurs capital expenditure for the purposes of a trade or part of a trade not yet carried on by him but with a view to carrying it on, or incurs capital expenditure in connection with a dock or other premises not yet occupied by him for the purposes of a qualifying trade but with a view to so occupying the dock or premises, the foregoing provisions of this section shall apply as if he had been carrying on the trade or part of the trade or occupying the dock or premises for the purposes of the qualifying trade, as the case may be, at the time when the expenditure was incurred.

• (8) For the purposes of this section, the first relevant year of assessment, in relation to expenditure incurred by any person, is the year in his basis period for which he incurs the expenditure or, in the case of expenditure for which allowances are to be made by virtue of subsection (7) of this section, the first year of assessment in his basis period for which he both carries on the trade or part of the trade for the purposes of which the expenditure was incurred and occupies for the purposes of that trade or part of the trade the dock or other premises in connection with which it was incurred.

• (9) Where a person contributes a capital sum to expenditure on dredging incurred by another person, he shall, for the purposes of this section, be treated as incurring capital expenditure on that dredging equal to the amount of the contribution and the capital expenditure incurred by the other person on that dredging shall, for those purposes, be deemed to be reduced by the amount of the contribution.

• (10) In this section “dredging” does not include things done otherwise than in the interests of navigation, but (subject to that) includes the removal of anything forming part of or projecting from the bed of the sea or of any inland water, by whatever means it is removed and whether or not at the time of removal it is wholly or partly above water; and this section shall apply to the widening of an inland waterway in the interests of navigation as it applies to dredging.

• (11) No allowance shall be made by virtue of this section in respect of any expenditure if for the same or any previous or subsequent year of assessment an allowance is or can be made in respect of it under Part IV of Finance (Miscellaneous Provisions) Act, 1956, or Chapter I of this Part.

• (12) Notwithstanding any other provision of this section, no allowance under this section shall be made for any year of assessment beginning before the commencement of this Part of this Act but, in determining the allowances to be made under this section in any particular case, there shall be deemed to have been made in that case all such allowances (other than initial allowances) as could have been made if this section had always had effect.

Chapter V. Miscellaneous and General.

58 Manner of granting allowances and charging tax in certain cases.

Provided that where the allowance is available primarily against income of the specified class and the amount of the allowance is greater than the amount of the person's income of that class for the first-mentioned year of assessment, he may, by notice in writing given to the inspector of taxes not later than one year after the end of the year of assessment, elect that the excess shall be deducted from or set off against his other income for that year of assessment, and it shall be deducted from or set off against that income and tax discharged or repaid accordingly and only the excess, if any, of the amount of the allowance over all his income for that year of assessment shall be deducted from or set off against his income of the specified class for succeeding years.

• (4) The Special Commissioners shall hear and determine an appeal to them under subsection (3) of this section as if it were an appeal against an assessment to income tax, and the provisions of the Income Tax Acts relating to the rehearing of an appeal and the statement of a case for the opinion of the High Court on a point of law, shall, with the necessary modifications, apply accordingly.

• (5) If any person, for the purpose of obtaining for himself or any other person any relief from or repayment of tax in respect of such an allowance as is mentioned in subsecton (1) of this section, knowingly makes any false statement or false representation, he shall be liable to a penalty of five hundred pounds.

60 Meaning of “basis period” .

60.—(l) In this Part of this Act, “basis period” has the meaning assigned to it by the following provisions of this section.

• (2) In the case of a person to or on whom an allowance or charge falls to be made in charging the profits or gains of his trade, his basis period for any year of assessment is the period on the profits or gains of which income tax for that year falls to be finally computed under Case I of Schedule D in respect of the trade in question or, where, by virtue of any Act, the profits or gains of any other period are to be taken to be the profits or gains of the said period, that other period:

Provided that, in the case of any trade—

• (a) where two basis periods overlap, the period common to both shall be deemed for the purpose of this subsection to fall in the first basis period only,

• (b) where there is an interval between the end of the basis period for one year of assessment and the basis period for the next year of assessment, then, unless the secondmentioned year of assessment is the year of the permanent discontinuance of the trade, the interval shall be deemed to be part of the second basis period, and

• (c) where there is an interval between the end of the basis period for the year of assessment preceding that in which the trade is permanently discontinued and the basis period for the year in which it is permanently discontinued, the interval shall be deemed to form part of the first basis period.

• (3) Any reference in the proviso to subsection (2) of this section to the overlapping of two periods shall be construed as including a reference to the coincidence of two periods or to the inclusion of one period in another, and references to the period common to both of two periods shall be construed accordingly.

• (4) Where an allowance or charge falls to be made under Chapter II of this Part of this Act to or on a person carrying on or holding a profession, employment, vocation or office, the provisions of the preceding subsections of this section shall apply as if the references to a trade included references to a profession, employment, vocation or office and as if the reference to Case I of Schedule D included references to Case II of Schedule D and to Schedule E.

• (5) In the case of any other person to or on whom an allowance or charge falls to be made under this Part of this Act, his basis period for any year of assessment is the year of assessment itself.

61 Apportionment of consideration and exchanges and surrenders of leasehold interests.

61.—(1) Any reference in this Part of this Act to the sale of any property includes a reference to the sale of that property together with any other property and, where property is sold together with other property, so much of the net proceeds of the sale of the whole property as, on a just apportionment is properly attributable to the first-mentioned property shall, for the purposes of this Part of this Act, be deemed to be the net proceeds of the sale of the first-mentioned property, and references to expenditure incurred on the provision or the purchase of property shall be construed accordingly.

For the purposes of this subsection, all the property which is sold in pursuance of one bargain shall be deemed to be sold together, notwithstanding that separate prices are or purport to be agreed for separate items of that property or that there are or purport to be separate sales of separate items of that property.

• (2) The provisions of subsection (1) of this section shall, with the necessary adaptations, apply in relation to other sale, insurance, salvage or compensation moneys as they apply in relation to the net proceeds of sales.

• (3) This Part of this Act shall have effect as if any reference therein (including any reference in the preceding provisions of this section) to the sale of any property included a reference to the exchange of any property and, in the case of a leasehold interest, also included a reference to the surrender thereof for valuable consideration and any provisions of this Part of this Act referring to sales shall have effect accordingly with the necessary adaptations and, in particular, with the adaptations that references to the net proceeds of sale and to the price shall be taken to include references to the consideration for the exchange or surrender and references to capital sums included in the price shall be taken to include references to so much of the consideration as would have been a capital sum if it had taken the form of a money payment.

• (4) As respects any year of assessment beginning on or after the commencement of this Part of this Act, the preceding provisions of this section shall, with the necessary adaptations, have effect in relation to—

• (a) Rules 6 and 7 of the Rules applicable to Cases I and II of Schedule D, and

• (b) Part V of Finance Act, 1956,

as if the said Rules 6 and 7 and the said Part V were provisions of this Part of this Act.

62 Special provisions as to certain sales.

• (b) it appears with respect to the sale or with respect to transactions of which the sale is one, that the sole or main benefit which, apart from the provisions of this section, might have been expected to accrue to the parties or any of them was the obtaining of an allowance or deduction under Rule 6 or Rule 7 of the Rules applicable to Cases I and II of Schedule D, Part V of Finance Act, 1956, or any of the provisions of this Part of this Act.

References in this subsection to a body of persons include references to a partnership.

• (3) Where the sale is a sale of machinery or plant—

• (a) no initial allowance shall be made to the buyer, and

• (b) subject to the provisions of subsection (4) of this section, if the price which the property would have fetched if sold in the open market is greater than the amount which, for the purpose of determining whether any, and if so, what, balancing charge should be made on the seller in respect of the property under Chapter II of this Part of this Act, would be taken to be the amount of the capital expenditure incurred by the seller on the provision of the property, subsection (2) of this section shall have effect as if for each of the references to the price which the property would have fetched if sold in the open market there were substituted a reference to the said amount:

Provided that this subsection shall not apply in relation to a sale of machinery or plant which was never used if the business or part of the business of the seller was the manufacture or supply of machinery or plant of that class and the sale was effected in the ordinary course of the seller's business.

• (4)
• (a) Subject to subsection (5) of this section, where the sale is one to which paragraph (a) of subsection (1) of this section applies and paragraph (b) of that subsection does not apply, and the parties to the sale by notice in writing to the inspector of taxes so elect, the following provisions shall have effect:

• (ii) paragraph (b) of subsection (3) of this section shall not apply, and

• (iii) notwithstanding anything in the preceding provisions of this section, such balancing charge, if any, shall be made on the buyer on any event occurring after the date of the sale as would have fallen to be made on the seller if the seller had continued to own the property and had done all such things and been allowed all such allowances or deductions in connection therewith as were done by or allowed to the buyer.

• (b) The sum referred to in subparagraph (i) of paragraph (a) of this subsection is—

• (b) the circumstances are not at that time such that an allowance or charge under this Part of this Act falls or might fall to be made to or on that party in consequence of the sale,

but, except as aforesaid, this section shall have effect in relation to a sale notwithstanding that it is not fully applicable by reason of the non-residence of a party to the sale or otherwise.

• (6) In this section “control”, in relation to a body corporate, means the power of a person to secure, by means of the holding of shares or the possession of voting power in or in relation to that or any other body corporate, or by virtue of any powers conferred by the articles of association or other document regulating that or any other body corporate, that the affairs of the first-mentioned body corporate are conducted in accordance with the wishes of that person and, in relation to a partnership, means the right to a share of more than one-half of the assets, or of more than one-half of the income, of the partnership.

• (2) Where, after the setting up and before the permanent discontinuance of a trade, profession or vocation which at any time is carried on in partnership anything is done for the purposes thereof, any allowance or charge which, if the trade, profession or vocation had at all times been carried on by one and the same person, would have fallen to be made to or on him under any of the provisions of this Part of this Act, shall be made to or on the person or persons from time to time carrying on that trade, profession or vocation, and the amount of any such allowance or charge shall be computed as if that person or those persons had at all times been carrying on the trade, profession or vocation and as if everything done to or by his or their predecessors in the carrying on thereof had been done to or by him or them.

Provided that all the said persons shall be entitled to appear and be heard by the Special Commissioners or to make representations to them in writing.

• (2) This section applies in relation to any determination for the purposes of this Part of this Act of the price which property would have fetched if sold in the open market as it applies in relation to apportionments.

for this section, give rise to a balancing allowance or balancing charge in respect of any property to or on a company in relation to which a certificate under subsection (2) of section 3 of Finance (Miscellaneous Provisions) Act, 1958, has been given, then, whether the certificate is still in force or not, the following provisions of this section shall apply.

66 Interpretation of certain references to expenditure, etc.

66.—(1) References in this Part of this Act to capital expenditure and capital sums—

• (a) in relation to the person incurring the expenditure or paying the sums, do not include any expenditure or sum which is allowed to be deducted in computing, for the purposes of income tax, the profits or gains of a trade, profession, office, employment or vocation carried on or held by him, and

• (2) Any reference in this Part of this Act to the date on which expenditure is incurred shall be construed as a reference to the date when the sums in question become payable.
