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 31.3.24:

Rate	Profits band (£)	Rate (%)
Small profits rate	0 - 50,000	19
Marginal rate	50,001 - 250,000	26.5
Main rate	Over 250,000	25
Marginal relief fraction	3/200

Year to 31.3.23: All profits taxed at 19%
