Capital allowances explained 

What are capital allowances?

Capital allowances are akin to a tax deductible expense. They are available in respect of qualifying capital expenditure incurred on the provision of certain assets that are in use for the purposes of a trade or rental business. They effectively allow a taxpayer to write off the cost of an asset over a period of time.

The area of capital allowances is complex; there is no approved list of qualifying items of expenditure for capital allowances purposes. Entitlement must be established and qualifying expenditure must be properly identified by reference to the facts. Taxpayers must also satisfy a number of conditions established primarily through case law and Revenue precedence.


To find out what capital allowances could mean for your business, see our brochure: ‘Capital allowances explained’.
