Limited company year-end checklist
Close the books cleanly before accounts, Corporation Tax and Companies House filings are prepared.
Updated 6 August 2026 6 min
01
Finish the bookkeeping
- Reconcile every bank and card account through the year-end date.
- Issue or write off draft and overdue sales documents appropriately.
- Enter unpaid supplier bills, director-paid expenses and mileage.
- Confirm payroll, dividends and the director's loan account.
- Review fixed assets, loans, accruals, prepayments and stock where relevant.
- Attach supporting evidence to unusual or material transactions.
02
Review and approve
Use Accounting reports to compare the profit and loss, balance sheet and trial balance with your expectations. Resolve unexplained balances before approving draft accounts and the Corporation Tax computation.
03
Track the separate deadlines
- Statutory accounts to Companies House: usually 9 months after year end for an established private company.
- Corporation Tax payment: usually 9 months and 1 day after the accounting period ends.
- Company Tax Return: usually 12 months after the accounting period ends.
- Confirmation Statement: normally at least once every 12 months, with its own review period and deadline.
New companies, shortened periods, large companies and notices issued by HMRC can produce different dates. Treat the deadlines shown for your company as authoritative.
