What the checker tells you, and where the dates come from
Every UK company has two statutory clocks at Companies House, and both are public register data. The checker reads them live for the company you name and shows the penalty attached to missing each one. It never files anything and never changes the register.
The accounts deadline
A private company's annual accounts are due 9 months after its accounting reference date (the financial year end). A company's very first accounts are different: if the first period runs longer than 12 months, they are due 21 months after incorporation or 3 months after the accounting reference date, whichever is longer. A company incorporated on 1 January 2025 with a 31 January year end has until 1 October 2026 for its first accounts, then 31 October every year after that. Dormant companies are on exactly the same clock.
The confirmation statement deadline
The confirmation statement confirms the register is correct. Its review period runs 12 months from incorporation or from the last statement, and the company then has 14 days to file. The online fee is £50, paid once per 12-month payment period. Since 18 November 2025 the statement is also where each director provides their Companies House personal code after verifying their identity — a company cannot file it until every director has.
What missing each one costs
| Filing | Automatic penalty | Other consequences |
|---|---|---|
| Annual accounts | £150 up to 1 month late, £375 up to 3 months, £750 up to 6 months, £1,500 beyond — doubled if last year was late too | ‘Accounts overdue’ on the public register; a criminal offence; the registrar may begin strike-off |
| Confirmation statement | No fixed ladder | A late confirmation statement is an offence by the company and its directors: Companies House can fine the company up to £5,000 and strike it off the register. ‘Overdue’ shows on the register meanwhile. |
How to read the result
Each date shows the days remaining or the days overdue. Inside 30 days the row turns amber; past the date it turns red and the penalty band that already applies is shown. An extension is possible only before the accounts deadline and only for an event outside your control — our guide on extending the accounts filing deadline covers the application; if the date has passed, the accounts-overdue guide explains what happens next and how to catch up. Dormant companies file a one-page balance sheet; the how-to-file guide shows the exact example.
Free, no account. Dates come from the Companies House public register at the moment you check; the register itself is the authority. Want them watched? Reminders at 90, 30 and 7 days are free — see deadline reminders.
