Corporation tax
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.
