Confirmation statement vs annual accounts: what directors confuse
Every year, limited company directors must send Companies House two separate filings: the confirmation statement and the annual accounts. The names sound similar, they go to the same organisation, and they even use the same filing portal. Yet they do completely different jobs, on completely different deadlines. Mix them up and you can easily file one, forget the other, and learn about the mistake from a penalty notice. Here they are, side by side.
The confirmation statement: checking the facts
The confirmation statement, form CS01, is Companies House checking that its public register is still accurate. It confirms who the directors are, the registered office address, the share capital, the shareholders, the people with significant control, and the SIC code describing the business. It contains no financial figures at all. Think of it as the company's identity card: are the facts still right?
The deadline runs from your incorporation date, not your financial year end. Your review period ends twelve months after incorporation, or twelve months after your last statement, and you have fourteen days from that date to file. There is a fee, currently 50 pounds to file online, and you pay it each time, even if nothing has changed, which it often has not. Filing when nothing has changed is the most common use case of all: you review, confirm, pay, done.
Since November 2025, every director must have verified their identity with Companies House and hold a personal code, or the confirmation statement cannot be filed. Get this done well before your statement date.
Miss the confirmation statement and there is no automatic fine like HMRC's penalties. The risk is worse: Companies House can begin striking the company off the register. Strike-off dissolves the company, its bank balance and other assets can pass to the Crown, and directors who kept trading afterwards can be held personally liable for debts.
The annual accounts: reporting the numbers
Annual accounts are the financial statements: the profit and loss account, the balance sheet, and the notes, filed under the Companies Act and shown to the world. For small and micro companies, the filing can use simplified formats, but it is still a real set of numbers, not a confirmation exercise.
The deadline is nine months after the end of your financial year, a completely different date from the confirmation statement. For a company with a December year end, accounts are due by 30 September; the confirmation statement date depends on the incorporation month. First-year accounts get twenty-one months from incorporation to file. Companies House applies automatic late-filing penalties that start at 150 pounds and rise to 1,500 pounds, doubling if you are late two years in a row. Unlike the confirmation statement, accounts carry no fee to file.
The preparation matters too: accounts are drawn from your bookkeeping, and anything on the balance sheet, including director's loans, is visible to anyone who looks the company up.
The side-by-side comparison
- Purpose: the confirmation statement checks that company details are correct; the annual accounts report the financial results.
- Contents: CS01 lists directors, shareholders, share capital, SIC code, registered office; accounts show profit, loss, assets, liabilities and notes.
- Deadline: confirmation statement within fourteen days of the annual review date; accounts nine months after the financial year end.
- Fee: confirmation statement costs 50 pounds to file online; accounts are free to file.
- Late penalty: late confirmation statements risk strike-off; late accounts attract automatic fines from 150 pounds.
- Even if dormant: both must still be filed.
Who prepares each one
You can file both yourself through Companies House WebFiling. The confirmation statement genuinely takes ten minutes if your details have not changed. The annual accounts are a different proposition: they require proper bookkeeping, knowledge of the reporting standards for small companies, and care with the notes and disclosures.
Most small companies outsource the accounts while handling the confirmation statement themselves, or delegate both. What matters is that someone tracks both dates.
What happens when directors mix them up
The two most common mistakes are mirror images. The first: filing the confirmation statement on time and assuming that covers everything, then missing the accounts deadline nine months later and collecting a 150-pound fine. The second: preparing beautiful accounts with an accountant and assuming compliance is complete, while the confirmation statement quietly goes overdue and strike-off proceedings begin.
They also get confused in conversation with accountants. "Have you done the annual filing?" can mean either one, so ask for both by name. And remember that neither of them is the corporation tax return, which goes to HMRC, not Companies House, on yet another deadline.
Keeping company compliance on track is exactly what professional management accounting services include: the bookkeeping, the management packs and the deadlines calendar, handled together. If Companies House filings are just one part of an admin load that keeps growing, Finex Outsourcing takes the whole function, so every filing lands on time and nothing falls between the cracks.
