Capital Allowances Manual

General: claims: Income Tax

In Income Tax cases capital allowance claims are made in the return (apart from the few exceptional cases - CA11120). The time limit for making a claim or amending a claim is the normal time limit for making or amending a tax return. That time limit is the first anniversary of 31 January following the year of assessment. For example, the capital allowance claim for 2010/2011 can be amended at any time up until 31 January 2013 because 31 January following the year of assessment 2010/2011 is 31 January 2012 and the first anniversary of that is 31 January 2013.

Where a business is carried on in partnership it is the partnership that claims the capital allowances and not the individual partners.

Example Rick and Frank are in partnership. They draw up their accounts to 30 June each year. In the year ended 30 June 2011 the partnership buys a helicopter for £100,000. Any capital allowance claim on the helicopter must be made by the partnership of Rick and Frank. It is not possible for either Rick or Frank to claim capital allowances on the helicopter in his own right.
