How to file business accounts: a private limited company checklist
Annual accounts, a confirmation statement and a Company Tax Return are different obligations. This guide covers ordinary private limited companies; sole traders and other structures have different requirements.
Quick answer
Reconcile the company’s financial records, prepare accounts under the appropriate standards, obtain the required approval and file through a permitted route. Track Companies House and HMRC deadlines separately. Directors remain responsible even when an accountant prepares and submits the documents.
Key points
- Confirm the accounting period and exact filing deadline.
- Use the current filing route and retain acceptance receipts.
- Do not confuse tax payment with filing the tax return.
Prepare reliable year-end information
Reconcile bank and card accounts, outstanding invoices, suppliers, payroll, tax, stock, fixed assets and borrowing. Resolve unexplained balances and record accruals or other year-end adjustments with appropriate advice. Distinguish director loans from company trading income.
HMRC’s guidance lists the balance sheet, profit-and-loss account and notes among statutory account components, with additional requirements depending on the company. Small, micro and dormant companies can have different reporting options; do not choose a simplified regime without checking eligibility.
Keep filing and payment deadlines separate
The ordinary deadlines shown by GOV.UK differ by obligation. First accounts and changed accounting periods need particular care, and some companies have different tax-payment arrangements. Check the actual company record and accountant’s advice rather than relying only on a generic table.
A Corporation Tax payment can be due before the Company Tax Return. Filing accounts does not automatically settle the tax or submit every other return.
| Obligation | Usual deadline |
|---|---|
| First Companies House accounts | 21 months after incorporation |
| Subsequent Companies House accounts | 9 months after financial year end |
| Corporation Tax payment | 9 months and 1 day after the tax accounting period |
| Company Tax Return | 12 months after the tax accounting period |
Approve the accounts and use the current submission route
Make sure the required approval and balance-sheet signature are completed. Use the current Companies House filing service or appropriate software for the company’s account type. Keep authentication details secure and authorise any agent correctly.
GOV.UK’s current filing guidance says commercial software is needed for the Company Tax Return, subject to limited paper-filing exceptions. Some software can support filing to both bodies; do not assume an old combined government service remains available.
Check acceptance and correct errors properly
Keep receipts and verify that the submission was accepted, not merely uploaded or sent to an accountant. If an error is found, follow the relevant accounts-amendment or tax-return correction process and obtain advice about any payment consequences.
Reliable filings can also support business-loan and credit-card applications, but accurate accounts are not a guarantee of approval. Keep current management figures too: lenders may need to understand trading since the filed year end.
Check the company’s reporting category
Eligibility for small, micro or dormant reporting depends on the actual rules and circumstances, not the owner’s informal description of the business. Different accounts can involve different disclosures, and an exemption from audit is not the same as an exemption from preparing accounts.
Ask the accountant which framework and filing option applies and why. Keep the full records needed for shareholders, tax and management even where a permitted public filing contains less information. Do not omit a liability because it is inconvenient or assume that a simplified filing makes underlying records unnecessary. The financial statements should reflect the company’s position under the appropriate requirements.
Identify the correct period before preparing figures
Check the accounting reference date, incorporation date and any changes to the financial year. A first set of accounts or a changed period can create requirements that differ from an ordinary twelve-month cycle. The tax accounting period may also need separate attention.
Agree the dates with the accountant before exporting records or calculating deadlines. Clearly label management accounts and statutory accounts so they are not confused in a finance application. If a lender requests recent trading, filed accounts from an earlier period may need to be supplemented. Current information helps explain the business but does not justify changing historic figures outside the proper correction process.
Treat rejection as an unresolved filing
A submitted file may be rejected or need correction. Keep acceptance evidence and check the company record where appropriate. If an agent is filing, ask for confirmation that identifies the company, period and accepted submission rather than only a message that work has been completed.
Allow time before the deadline for queries, signature, software issues and corrections. A last-minute upload leaves little room to resolve a problem. If the deadline may be missed, seek advice and use the official process relevant to the circumstances rather than assuming an accountant’s involvement prevents penalties. Keep a clear action list so responsibility is not lost between the director, bookkeeper and filing agent.
Use the accounts appropriately in a finance application
A lender may use accounts alongside bank records, credit information and forecasts. Explain significant changes since the year end, unusual items and current commitments. Do not present a historic profit as proof that the same amount of cash is available today.
Reconcile the figures used in a business-loan request with the underlying records and identify any forecasts clearly. If an application requires information beyond the public filing, provide it through a verified secure route. Accurate accounts improve the evidence available, but the provider still makes its own assessment. The purpose of compliance and reliable records is broader than obtaining credit, and neither filing on time nor showing a profit guarantees approval.
Use a director’s final review checklist
Confirm the legal entity, period, reporting basis, required approval, submission route and exact deadlines. Check that the figures reconcile to supporting records and that unusual balances have been explained. Ask which filings and payments remain outstanding after the accounts are submitted.
Keep the accepted version and confirmation safely accessible. If the figures are later used for finance, identify any management updates separately rather than altering the filed document informally. A short documented review helps the director understand what has been approved and avoids assuming one submission completes every company and tax obligation. Seek professional help where the answer remains uncertain.
Common questions
- Does my accountant take over the director’s responsibility?
- No. Professional help is valuable, but directors retain their legal responsibilities and should check approval, submission and acceptance.
- Is a confirmation statement the same as annual accounts?
- No. They serve different purposes and have separate requirements. Track both rather than treating one submission as completing the other.
