About the ACA

The Accelerated Capital Allowance (ACA) is a tax incentive which aims to encourage companies to invest in energy saving technology.The ACA allows companies to write off 100% of the purchase value of qualifying energy efficient equipment against their profit in the year of purchase.

The ACA is based on the existing Capital Allowances tax structure (also referred to as Wear and Tear Allowance) for plant and machinery and is only applicable to eligible energy efficient equipment. Claiming the ACA is also carried out the same way as for the standard Capital Allowances.

The ACA was introduced in the Finance Act, 2008, for a trial period of three years and was extended until 31 December 2014 in the Finance Act, 2011.  The scheme was further extended until the end of 2017 following the National Budget in November 2014.
