Questions
When are a private limited company's accounts due?
Usually 9 months after the end of the company's financial year. A company's first accounts are normally due 21 months after it was incorporated. Public limited companies have 6 months.
When is the confirmation statement due?
At least once every 12 months. You have 14 days after the end of the review period to file it.
When is Corporation Tax due?
For most companies, Corporation Tax is payable 9 months and 1 day after the end of the accounting period, and the CT600 return is due 12 months after the end of the period. Large companies pay by quarterly instalments.
Where does the checker get its data?
Accounts and confirmation statement dates come live from Companies House. Corporation Tax dates are estimated from the accounts period end, which usually matches the Corporation Tax accounting period. Always check with your accountant or HMRC before relying on them.
What happens if accounts are filed late?
Companies House charges an automatic late filing penalty, which goes up the later the accounts are, and doubles if accounts are late two years running. HMRC charges separate penalties for late Corporation Tax returns.
