Corporation tax

Companies pay corporation tax on their income and gains. View the current rates and estimate the tax due.

Corporation tax rates are set for each Financial Year. A Financial Year runs from 1 April to the following 31 March.

If the accounting period of a company straddles the 31 March, the profits are apportioned on a time basis to each Financial Year.

The Northern Ireland Executive has committed to setting the rate of corporation tax at 12.5% when the Northern Ireland Executive demonstrates its finances are on a sustainable footing.

Year to 31.3.25:

Marginal rate 50,001 - 250,000 26.5
