If your taxable profits are less than £1.5 million, your Corporation Tax deadline will normally be 9 months and 1 day from the end of your accounting period. This applies after your first year of trading as the deadline for your first return can sometimes be slightly sooner. You’ll receive notification from HMRC when your Corporation Tax is due.
The end of your accounting period is normally the month end of the anniversary of your incorporation.
If you’ve made more than £1.5 million in profits, you’ll have to pay your Corporation Tax in instalments. Assuming your company has a 12 month accounting period, your instalment dates will be:
- 6 months and 13 days after the first day of your accounting period
- 3 months after your first instalment
- 3 months after your second instalment
- 3 months and 14 days after the last day of your accounting period
