Companies House deadline checker

Every UK limited company has two Companies House filings each year, the annual accounts and the confirmation statement, plus a corporation tax return to HMRC. Enter two or three dates and see when each is due, and what you owe if you're already late.

All these dates are on your company's free page at Find and update company information. Its "due by" dates are the official ones; this checker shows the same rules and the penalty.

The three yearly deadlines

FilingWho it goes toWhen it's due
Annual accountsCompanies House9 months after the year end (private), 6 months (public). First accounts: 21 months after incorporation (private), 18 months (public).
Confirmation statementCompanies HouseWithin 14 days after the statement date, at least once every 12 months. A fee is due each time.
Corporation tax return (CT600)HMRC12 months after the end of the accounting period. The tax itself is due 9 months and 1 day after it.

If your year end is the last day of a month, the accounts deadline is the last day of the month too. A 30 June year end is due 31 March, not 30 March.

Late filing penalties for accounts

How latePrivate companyPublic company
Up to 1 month£150£750
1 to 3 months£375£1,500
3 to 6 months£750£3,000
More than 6 months£1,500£7,500

The penalty doubles if the previous year's accounts were also late. It is charged to the company automatically, and only a few reasons are accepted on appeal (serious illness, a fire or flood, a Companies House error). See how to appeal a Companies House late filing penalty.

A late confirmation statement

There's no automatic fine, but not filing is a criminal offence for the company and its directors, and Companies House can start striking the company off the register. Since 18 November 2025 the statement also can't be filed until every director has verified their identity, so check your director ID verification deadline first.

Directors living outside the UK

Many UK companies are run from India, the US, the UAE or Nigeria after being set up through a formation agent. The deadlines are the same wherever you live, the penalties are charged to the company, and Companies House letters go to the registered office, which is often the agent's address. If your agent's service has lapsed, you may not see the reminders at all.
