First Companies House accounts are usually due 21 months after incorporation, and later accounts 9 months after the financial year ends. Corporation Tax is usually paid 9 months and 1 day after the tax accounting period ends, and the Company Tax Return is due 12 months after.
The Company Tax Return (CT600) is due 12 months after the end of the accounting period, but the tax is usually due 9 months and 1 day after the end of the period. If the return is late, HMRC charges £200, then another £200 at 3 months.
Companies House charges £150 to £1,500 for late accounts, doubled if they are late 2 years in a row. HMRC charges £200 upwards for a late CT600. Filing one on time does not stop a penalty on the other, and each office runs its own appeal process.
