Companies House Filing Deadlines
Miss a deadline and you will face automatic penalties — no warnings, no grace period. Here is every filing a UK limited company must make and when it is due.
Confirmation Statement
Due at least once every 12 months from the date of incorporation (or the date the last statement was made). It confirms that the information Companies House holds about your company is correct — registered office, directors, shareholders, SIC codes, and PSCs. Filing costs £13 online or £40 on paper. If you do not file, Companies House can start proceedings to strike the company off the register.
Annual Accounts
Your first accounts are due 21 months after incorporation. After that, they are due 9 months after the end of each financial year (the accounting reference date). Most small companies file micro-entity or small company accounts, which require less detail. The accounts must be approved by the board and signed by a director before filing.
Corporation Tax Return
Filed with HMRC (not Companies House) within 12 months of the end of the accounting period. However, the tax itself must be paid within 9 months and 1 day. Even if your company made no profit, you still need to file a return.
Late Filing Penalties
| How late | Private company | Public company |
|---|---|---|
| Up to 1 month | £150 | £750 |
| 1 – 3 months | £375 | £1,500 |
| 3 – 6 months | £750 | £3,750 |
| Over 6 months | £1,500 | £7,500 |
Penalties double if your accounts are late two years in a row.
