Revenue Note for Guidance
This section sets out the due dates for the payment of corporation tax by companies other than those with “relevant accounting periods”, that is, small companies and those with short accounting periods. Preliminary tax is payable in one instalment and is due 31 days before the end of the accounting period (i.e. normally in month 11 of the accounting period) – but no later than day 21 (or day 23 for electronic filers) of the month involved. Corporation tax is, in general, due by the return filing date for the accounting period. However, if relevant preliminary tax requirements have not been met, the due date reverts to the due date for the payment of preliminary tax.
A small company (as defined in section 959AM(1)) and a company with a short accounting period (under section 959AM(2)) make a single payment of preliminary tax. The preliminary tax appropriate to an accounting period is due and payable:
The balance of tax payable is due by the specified return date.
Any tax due and payable under an assessment on the company will also be due and payable before the specified return date .
The balance of tax shall be deemed to have been due on the due date for preliminary tax where:
When determining whether or not a company with a short accounting period met the 90% test, and
then the chargeable person will have met their preliminary tax obligations under this section.
