CA75100 - Patents: Allowances: Qualifying expenditure

CAA01/S467 - S469, CAA01/S481

Patent allowances are capital allowances given on capital expenditure incurred on the purchase of patent rights.

The current system of patent allowances applies to expenditure incurred on or after 1 April 1986. The system is similar to the system of plant and machinery allowances in that expenditure is normally pooled and allowances are given at an annual rate of 25% on the reducing balance basis. The system for expenditure incurred before 1 April 1986 is described at CA75140.

The expenditure on which patent allowances are given is called qualifying expenditure. Qualifying expenditure is either qualifying trade expenditure or qualifying non-trade expenditure.

Qualifying trade expenditure is 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 that person. Pre-trading expenditure on buying patent rights is treated as incurred on the first day of trading provided that the person owns the rights on that date.

Qualifying non-trade expenditure is capital expenditure incurred by a person on the purchase of patent rights that is not qualifying trade expenditure provided that income receivable from those rights is liable to tax.

Qualifying expenditure is restricted if a person buys patent rights and either:

• the person buying the rights is connected with the seller, or
• the sale is a sole or main benefit transaction. A sole or main benefit transaction is one, or one of a series, where the sole or main benefit, which might be expected to accrue to the parties, is the obtaining of a patents allowance.

In those cases the buyer's expenditure qualifying for capital allowances is restricted to:

1. the seller's disposal value if there is one,
2. if the seller has no disposal value but receives a capital sum which is chargeable that capital sum,
3. if neither (a) nor (b) applies the smallest of:
