When are my company accounts due at Companies House?
Enter your company number to see your exact accounts deadline, and get reminded before it, in seconds.
The quick answer
For an established private limited company, your annual accounts are due 9 months after your accounting reference date (usually the anniversary of the month you incorporated). In your very first year the deadline is longer: 21 months from the date of incorporation. Your exact date is on the public register, enter your company number above and we'll show it, along with how many days you have left.
How to find your accounting reference date
Your accounting reference date (ARD) is set when the company is formed, the last day of the month of the anniversary of incorporation. For example, a company incorporated on 12 March has an ARD of 31 March, so its accounts for the year to 31 March are due by 31 December (9 months later). You can change your ARD, which shifts the deadline, and we always read the current one straight from Companies House rather than assuming.
Don't rely on doing the maths
Working it out by hand is exactly how deadlines get missed, especially if the ARD has ever been changed or it's the unusual first-year window. Rather than calculate it, just look it up: enter your company name or number and see the real date and the days remaining free. Add Monitoring (£15/mo) and we'll remind you at 30, 14, 7 and 1 days before, and on the day.
What if they're already overdue?
If your accounts are already late, file them as soon as possible, the penalty rises the longer you leave it (from £150 up to £1,500 for a private company) and doubles if you were also late the year before. Our lookup will tell you plainly if you're currently overdue.
Deadlines are read from the public Companies House record; penalty figures can change, check GOV.UK. General information, not legal or accounting advice.
