Corporation tax rates are set for each financial year. A financial year runs from the 1 April to 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 profit limits are reduced for accounting periods of less than 12 months and for a company with associated companies. A company is an associated company of another company if one of the two has control of the other, or both are under the control of the same person or persons. A company may be an associated company no matter where it is resident for tax purposes.
