Companies House filing deadlines every director should know
Running a company brings a handful of filing obligations to Companies House that do not go away and do not move just because the business is busy. Miss them and the costs are real: automatic penalties, a public mark on the company’s record, and in the worst case the company being struck off. Hit them cleanly and you build something quietly valuable — a tidy public record that lenders and counterparties read as a sign of a well-run business. This is a plain-English run through the main deadlines and why they matter. It is general information; for your company’s specific dates and duties, check the record and take your own professional advice.
Annual accounts
Every company must prepare and file annual accounts. The filing deadline runs from the company’s accounting reference date — the end of its financial year. For an established private company, accounts are generally due at Companies House within nine months of that year-end. A brand-new company’s first set runs on a longer clock, because its first accounting period is usually longer than a year. The format depends on the size of the company: smaller companies can often file simpler accounts, while larger ones file in full. Your accountant will know which regime applies.
Accounts are also filed with HMRC as part of the company’s tax return, on a separate timetable. The two are related but not the same deadline, and it is easy to satisfy one and forget the other. Keeping a single calendar of every obligation — Companies House and HMRC — is the simplest way to avoid a slip.
The confirmation statement
Separately from accounts, every company must file a confirmation statement at least once a year. This is the filing that confirms the information on the public register is still correct: registered office, directors, share capital, shareholders and the persons with significant control. It does not restate the company’s finances; it confirms the company’s details. If nothing has changed you confirm that; if something has, you update it. There is a window after the statement’s review date in which to file, and the obligation recurs every year whether or not anything has moved.
The consequences of filing late
Late accounts trigger an automatic civil penalty that rises with the length of the delay, and the penalty doubles if accounts are filed late two years running. The penalty is on the company, it is not discretionary, and pleading that the business was busy does not remove it. Persistent failure to file is more serious still: it can lead to the registrar striking the company off the register and to action against the directors. A director who repeatedly fails to file is not meeting a basic statutory duty.
Beyond the penalty, there is a reputational cost. A late-filing marker, an overdue accounts flag, or a company in “proposal to strike off” status all sit on the public record for anyone to see. That includes anyone deciding whether to extend credit, supply on terms, or do business at all.
Why a clean filing record helps your credit standing
Here is the part that connects directly to borrowing. When a lender or a credit bureau assesses a company, the Companies House record is one of the first things they look at. Up-to-date accounts, an on-time confirmation statement, and no overdue or strike-off markers all read as signs of a business that is in control of its affairs. The opposite — overdue accounts, a lapsed confirmation statement — reads as risk, regardless of how the business is actually trading.
A clean record is one of the cheapest things a company can do to improve how it is seen by anyone extending credit. Our guide to building business creditworthiness puts on-time filing near the top of the list for exactly this reason, and our explainer on business credit scores shows how filing data feeds the score a company carries. When Credicorp assesses an incorporated borrower, the public record is part of the picture — another reason we lend to incorporated businesses only: the borrower is verifiable on a public register in a way a sole trader is not.
A simple routine that keeps you clear
Most filing trouble comes from dates being forgotten, not from anything hard. Three habits prevent almost all of it. First, put the accounts deadline, the confirmation-statement date and the HMRC dates in one shared calendar with reminders well ahead of each. Second, keep the registered office and the PSC details current as they change, rather than fixing everything in a panic at confirmation time. Third, file early — the deadline is a limit, not a target, and filing with weeks to spare leaves room for the inevitable query. None of this needs a finance team; it needs a calendar and a habit.
The honest summary
The two recurring Companies House obligations every director should hold in mind are the annual accounts and the confirmation statement, each on its own clock. Filing late brings automatic, rising penalties and a public mark on the record; persistent failure can cost the company its place on the register. A clean filing history, by contrast, is a quiet asset — it tells lenders, suppliers and counterparties that the company is well run, and it feeds directly into how creditworthy the business looks. The dates are knowable and the routine is simple. For your company’s exact deadlines, check the record and take your own professional advice.
