PM163240 | The Annual Investment Allowance (AIA)

The Annual Investment Allowance is available to businesses regardless of size. It was introduced for expenditure incurred on or after 1 April 2008 for CT purposes and on or after 6 April 2008 for IT purposes. Detailed guidance can be found at CA23080 onwards.

It is important to note, however, that partnerships are only eligible to claim the allowance if all the members are individuals. A partnership of which a company is a member is not a qualifying person for Annual Investment Allowance (AIA) purposes and so cannot claim AIA. A partnership which includes another partnership as a member, e.g. an LLP, is not a qualifying person for AIA purposes. Please refer to the guidance at CA23082.
