A company which has seven wholly-owned subsidiaries has taxable total profits of £140,000 for the year to 31 March 2024.

Dividends received in the year were £50,000. Calculate the corporation tax liability for the year and state the date (or dates) on which this tax is due to be paid, assuming that the company was ”large” for payment by instalments purposes in the year to 31 March 2023 and either:

(a) all of the dividends received were intra-group dividends, or

(b) none of the dividends received were intra-group dividends.
