Accelerated Capital Allowance


Accelerated Capital Allowance (ACA)

Want to reduce your tax bill and your energy costs? Accelerated Capital Allowance is a tax incentive encouraging investment in energy saving technology.

ACA and Triple E

The Accelerated Capital Allowance (ACA) is a tax incentive scheme that promotes investment in energy efficient products & equipment. The ACA is based on the long-standing ‘Wear and Tear Allowance’ for investment in capital plant and machinery, whereby capital depreciation can be compensated through a reduction in an organisation’s tax liability.

All PV Solar Ireland Products are Tripple E Registered

The ACA scheme allows a sole trader, farmer or company that pays corporation tax or income tax on trading or professional income in Ireland to deduct the full cost of the equipment from their profits in the year of purchase. As a result, the business’s taxable profits are reduced by the value of qualifying capital expenditure. By contrast, the Wear and Tear Allowance provides for the same tax reduction, but this is spread evenly over an eight-year period.

Eligibility for ACA

Companies, sole traders and farmers that operate and pay corporation tax or income tax on trading or professional income in Ireland can avail of the ACA scheme.

Equipment use

The equipment purchased must be new and bought for use in a trade. It cannot be leased, let or hired to any person, body or organisation.

Time period

ACA can be claimed for the accounting period in which the equipment was first provided, as long as the equipment is included on the published list at some stage during that accounting period.

Eligible costs and minimum expenditure

ACA is available for costs directly related to providing the equipment. Expenditure on the technology must be equal to or exceed the minimum amounts for the relevant class of technology.
