Your company’s corporation tax bill is payable nine months and one day after the end of the company’s accounting period, so by 1 October for a period that ended on the previous 31 December.

The corporation tax bill may be the largest single tax payment you make in the year, so it’s essential to get it right. Check these points:

• Does the amount you are paying agree with the accounts and tax computation? You can pay an estimated amount if the tax return hasn’t been filed yet
