Part 8 U.K. Patent allowances

Chapter 1 U.K. Introduction

464 Patent allowances U.K.

(1) Allowances are available under this Part if a person incurs qualifying expenditure on the purchase of patent rights.

(2) In this Part “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.

465 Future patent rights U.K.

(1) References in this Part to expenditure incurred on the purchase of patent rights include expenditure incurred on obtaining a right to acquire future patent rights.

(2) If a person—

(a) incurs expenditure on obtaining a right to acquire future patent rights, and

(b) subsequently acquires those rights,

the expenditure is to be treated as having been expenditure on the purchase of those rights.

(3) “A right to acquire future patent rights” means a right to acquire in the future patent rights relating to an invention in respect of which the patent has not yet been granted.

(4) References in this Part to the proceeds of a sale of patent rights include a sum received from a person which is treated under this section as expenditure incurred by him on the purchase of patent rights.

466 Grant of licences U.K.

(1) The acquisition of a licence in respect of a patent is to be treated as the purchase of patent rights.

(2) The grant of a licence in respect of a patent is to be treated as a sale of part of patent rights.

(3) But the grant by a person entitled to patent rights of an exclusive licence is to be treated as a sale of the whole of those rights.

(4) “Exclusive licence” means a licence to exercise those rights to the exclusion of the grantor and all other persons for the period remaining until the rights come to an end.

Chapter 2 U.K. Qualifying expenditure

467 Qualifying expenditure U.K.

Expenditure is qualifying expenditure only if it is—

(a) qualifying trade expenditure, or

(b) qualifying non-trade expenditure.

468 Qualifying trade expenditure U.K.

(1) “Qualifying trade expenditure” means capital expenditure incurred by a person on the purchase of patent rights for the purposes of a trade within the charge to tax carried on by the person.

(2) The same expenditure may not be taken into account as qualifying trade expenditure in relation to more than one trade.

(3) Expenditure incurred for the purposes of a trade by a person about to carry on the trade is to be treated as if it had been incurred by him on the first day on which he carries on the trade.

(4) But subsection (3) does not apply if the person has before that day sold all the rights on the purchase of which the expenditure was incurred.

469 Qualifying non-trade expenditure U.K.

“Qualifying non-trade expenditure” means capital expenditure incurred by a person on the purchase of patent rights if—

(a) any income receivable by the person in respect of the rights would be liable to tax, and

(b) the expenditure is not qualifying trade expenditure.

Chapter 3 U.K. Allowances and charges

470 Pooling of expenditure U.K.

(1) Qualifying expenditure has to be pooled for the purpose of determining a person’s entitlement to writing-down allowances and balancing allowances and liability to balancing charges.

(2) There is a separate pool—

(a) for each trade in respect of which the person has qualifying trade expenditure, and

(b) for all of the person’s qualifying non-trade expenditure.

471 Determination of entitlement or liability U.K.

(1) Whether a person is entitled to a writing-down allowance or a balancing allowance, or liable to a balancing charge, for a chargeable period is determined separately for each pool of qualifying expenditure and depends on—

(a) the available qualifying expenditure in that pool for that period (“AQE”), and

(b) the total of any disposal receipts to be brought into account in that pool for that period (“TDR”).

(2) If AQE exceeds TDR, the person is entitled to a writing-down allowance or a balancing allowance for the period.

(3) If TDR exceeds AQE, the person is liable to a balancing charge for the period.

(4) The entitlement under subsection (2) is to a writing-down allowance except for the final chargeable period when it is to a balancing allowance.

(5) The final chargeable period for a pool to which qualifying trade expenditure has been allocated is the chargeable period in which the trade is permanently discontinued.

(6) The final chargeable period for a pool to which qualifying non-trade expenditure has been allocated is the chargeable period in which the last of the patent rights on which the person has incurred qualifying non-trade expenditure—

(a) comes to an end without any of those rights being revived, or

(b) is wholly disposed of.

472 Amount of allowances and charges U.K.

(1) The amount of the writing-down allowance to which a person is entitled for a chargeable period is 25% of the amount by which AQE exceeds TDR.

(2) If the chargeable period is more or less than a year, the amount is proportionately increased or reduced.

(3) If in the case of qualifying trade expenditure the trade has been carried on for part only of the chargeable period, the amount is proportionately reduced.

(4) A person claiming a writing-down allowance may require the allowance to be reduced to a specified amount.

(5) The amount of the balancing charge to which a person is liable for a chargeable period is the amount by which TDR exceeds AQE.

(6) The amount of the balancing allowance to which a person is entitled for the final chargeable period is the amount by which AQE exceeds TDR.

473 Available qualifying expenditure U.K.

A person’s available qualifying expenditure in a pool for a chargeable period consists of—

(a) any qualifying expenditure allocated to the pool for that period in accordance with section 474, and

(b) any unrelieved qualifying expenditure carried forward in the pool from the previous chargeable period under section 475.

474 Allocation of qualifying expenditure to pools U.K.

(1) The following rules apply to the allocation of a person’s qualifying expenditure to a pool.

(2) An amount of qualifying expenditure is not to be allocated to the pool for a chargeable period if that amount has been taken into account in determining the person’s available qualifying expenditure for an earlier chargeable period.

(3) Qualifying expenditure is not to be allocated to the pool for a chargeable period before that in which the expenditure is incurred.

(4) Qualifying expenditure incurred on patent rights is not to be allocated to the pool for a chargeable period if in any earlier period those rights—

(a) have come to an end without any of them having been revived, or

(b) have been wholly disposed of.

475 Unrelieved qualifying expenditure U.K.

(1) A person has unrelieved qualifying expenditure to carry forward from a chargeable period if for that period AQE exceeds TDR.

(2) The amount of the unrelieved qualifying expenditure is—

(a) the excess less the writing-down allowance made for the period, or

(b) if no writing-down allowance is claimed for the period, the excess.

(3) No amount may be carried forward as unrelieved qualifying expenditure from the final chargeable period.

[F1 475A Unrelieved qualifying expenditure: entry to cash basis U.K.

(1) If a person carrying on a trade enters the cash basis for a tax year, any cash basis deductible amount may not be carried forward as unrelieved qualifying expenditure in the pool for the trade from the chargeable period ending with the basis period for the previous tax year.

(2) A “cash basis deductible amount” means any amount of unrelieved qualifying expenditure for which a deduction would be allowed in calculating the profits of the trade on the cash basis on the assumption that the expenditure was paid in the tax year for which the person enters the cash basis.

(3) Any cash basis deductible amount is to be determined on such basis as is just and reasonable in all the circumstances.

(4) Subsections (9) and (11) of section 1A (capital allowances and charges: cash basis) apply for the purposes of this section as they apply for the purposes of that section.]
