Capital Allowances Act 2001


1643.Income Tax Act 1945 introduced capital allowances for patent rights. It also introduced provisions dealing with the “revenue treatment” of capital profits from the sale of patent rights.

1644.Allowances were originally given for each separate item of capital expenditure on the purchase of patent rights. Those allowances were given on a straight line basis over, broadly, the life of the patent rights that had been bought. A balancing allowance was available on the disposal of the whole of the patent rights if the sale proceeds were less than the unrelieved cost of the patent rights at the time of the sale. Balancing charges were made if patent rights were sold for more than the unrelieved cost of the patent rights at the time of the sale.

1645.FA 1986 changed the way allowances are given. Capital expenditure on the purchase of patent rights incurred after 31 March 1986 is pooled. Allowances are given on the balance in the pool. There are also balancing allowances and charges similar to, but not identical with, those for plant and machinery.

1646.Both sets of provisions – for expenditure before and after the changes in 1986 – were consolidated in Chapter I of Part XIII of ICTA together with provisions about the “revenue treatment” of capital profits. These are sections 520 to 529 and 532 and 533 of ICTA.
