The £2,000 CT paid is repayable.

The carry-back has no consequences for late payment interest. Although the DTR has been displaced by a carry back of losses with a later effective date of payment, no additional amount of CT would have carried interest if the claim had not been made. However, COTAX will incorrectly charge interest in such a case. See for the action to take.
