Year-end is not just a compliance event — it is a test of your finance function's quality. Growth companies that approach 31 December without a structured plan routinely cause audit delays, create adjustments that surprise the board, and give investors a poor impression of financial controls. This guide covers the complete year-end process: what to do before the year closes, what typically gets left too late, the close timetable you should be running, and how to prepare for your auditors.
Why the 31 December Year-End Deserves Dedicated Attention
A 31 December year-end coincides with the Christmas and New Year period, which means that many of the people whose input is required for a clean close are unavailable for part of the critical closing window. This compresses the timeline and makes pre-year-end preparation more important than for any other year-end date.
Beyond timing, year-end accounts are the primary financial record that external stakeholders — investors, auditors, HMRC, banks, and potential acquirers — will use to assess the health of the business. Errors or omissions in year-end accounts have a shelf life: they sit in the statutory record and can surface in due diligence two or three years later. The cost of getting it right once is much lower than the cost of managing historical errors during a fundraising process.
For growth companies, the year-end process also typically triggers several concurrent obligations: corporation tax return preparation, R&D tax credit claims, the annual confirmation statement, and any regulatory reporting that is linked to the financial year. The close timetable needs to accommodate all of these, not just the audit.

Before Year-End: The Four-Week Checklist
The most effective year-end close starts at least four weeks before 31 December. The following checklist covers the items that should be completed in the run-up to year-end, rather than after it.
Cut-off and accruals (complete by 20 December)
1Review all open purchase orders and confirm which goods or services will be delivered before 31 December; raise accruals for all such costs even if invoices have not yet been received.
2Review all revenue contracts and confirm revenue recognition cut-off: identify any contracts where revenue has been invoiced but not yet earned (deferred revenue) or earned but not yet invoiced (accrued revenue).
3Calculate and post the salary and NIC accrual for December, including any December bonus accruals agreed by the board.
4Review prepayments: identify annual insurance, software subscriptions, and other expenses paid in advance that straddle the year-end and confirm the prepayment balance to be carried forward.
5Confirm the treatment of any outstanding legal disputes or claims: establish whether a provision is required under IAS 37 / FRS 102 and agree the quantum with your solicitors if applicable.
6Review all credit card and expense claims outstanding as at 31 December and ensure the relevant accrual is raised for expenses incurred but not yet processed.
Stock, WIP, and fixed assets
7If you hold physical stock, organise and complete a stock count before 31 December or as close as possible to year-end; document the counting process and reconcile to the stock management system.
8For software or product development capitalised as intangible assets, review the WIP balance: confirm what has been completed and should be transferred to a live asset, and what is still in development.
9Complete the fixed asset register review: confirm additions and disposals during the year, ensure depreciation has been correctly calculated, and verify that all assets are still in use.
10Assess right-of-use assets under IFRS 16 / FRS 102 Section 20: confirm lease modifications, extensions, or terminations that affect the balance sheet as at year-end.
Intercompany and bank
11Complete all intercompany reconciliations for group entities: every intercompany balance must agree between the entities, with any timing differences identified and agreed before year-end.
12Ensure the final December bank reconciliations are completed promptly in January; flag any reconciling items older than 30 days for resolution before the audit starts.
13For any foreign currency bank accounts, confirm the year-end exchange rates to be applied and calculate the FX retranslation adjustment.
14Obtain bank confirmation letters from all banking counterparties confirming balances as at 31 December; these are a standard audit requirement and take time to obtain.
VAT and payroll
15Confirm the December VAT position: if your VAT quarter ends 31 December, ensure the return is ready to submit promptly in January.
16Review the VAT account balance on the general ledger: the VAT liability or asset should reconcile precisely to the outstanding VAT return balance.
17Finalise the payroll for December before the year-end: ensure all December salaries, bonuses, and commission payments are processed and the payroll journal is posted.
18Confirm the PAYE liability as at 31 December reconciles to the balance on the PAYE control account in the general ledger.
What Gets Left Too Late and Causes Audit Delays
Even companies with good intentions routinely discover in January that certain items were not properly addressed before year-end. The following are the most common sources of audit delay and material post-close adjustment in growth companies:
"The issues that cause the most audit delays are rarely the complex ones. They are the revenue cut-off errors, the missing provisions, and the related-party transactions that nobody documented — all preventable with a structured close process."
Revenue cut-off (the most common audit adjustment)
19Review all revenue recognised in December: confirm that performance obligations under each contract had been fully satisfied by 31 December. Revenue recognised for services not yet delivered is a cut-off error.
20Identify all contracts signed in December where the service period starts in January: ensure no revenue has been recognised in the wrong period.
21Review the deferred revenue balance: confirm it agrees to the contracted but unearned revenue from all active contracts at year-end.
Provisions and contingencies
22Review all known legal disputes, pending regulatory actions, and warranty claims: assess whether a provision is required under IAS 37 (probable and estimable) or only a contingent liability disclosure is appropriate.
23Assess the provision for doubtful debts: review the aged debtors list and provide for debts where recovery is uncertain. The auditors will challenge a nil provision on debts that are more than 90 days overdue.
24Consider whether any restructuring provisions are required: if the board has approved and communicated a restructuring plan before 31 December, a provision may be required even if costs are not incurred until January.
Related parties and going concern
25Complete the related party transaction schedule: identify all transactions with directors, shareholders above 20%, and connected entities during the year. These are a statutory disclosure requirement and auditors will specifically request this information.
26Prepare the going concern assessment: for investor-backed companies, this requires a cash flow forecast covering at least 12 months from the accounts signing date, together with a sensitivity analysis. If the base case shows less than 12 months of runway, a more detailed assessment and potentially a disclosure will be required.
27Confirm director loan account balances and remuneration: directors' loan accounts outstanding at year-end have specific tax and disclosure implications under s.455 CTA 2010.

Preparing the PBC Schedule for Your Auditors
The PBC (Prepared By Client) schedule is the package of information you provide to your auditors at the start of fieldwork. A well-prepared PBC reduces audit time, reduces queries, and significantly reduces audit fees. A poorly prepared PBC does the opposite.
A complete PBC schedule for a growth company should include:
Core financial information
28Signed trial balance as at 31 December, with comparatives for the prior year.
29Draft P&L and balance sheet in the company's reporting format.
30Bank reconciliations for all bank accounts as at 31 December, with bank statements.
31Aged debtors and creditors listings as at 31 December.
Supporting schedules
32Fixed asset register with additions, disposals, and depreciation for the year.
33Accruals and prepayments schedule with supporting basis for each material item.
34Revenue recognition schedule: contracts, performance obligations, cut-off analysis, and deferred revenue workings.
35Intercompany balances and reconciliations, confirmed and agreed between entities.
36Share capital and shareholders' register, including any share option movements during the year.
Governance and compliance
37Board minutes for the year, including any material decisions affecting the accounts (capital expenditure approvals, restructuring decisions, bonus approvals).
38Related party transaction schedule, identifying all transactions with directors, shareholders, and connected parties.
39Going concern assessment and supporting cash flow forecast.
40Material contracts, leases, or commitments entered into during the year that have accounting implications.
A practical tip on PBC quality: before submitting your PBC to the auditors, have someone who was not involved in preparing it attempt to reconcile each schedule back to the trial balance. Every number the auditors see should tie to a source. A PBC where schedules do not reconcile creates additional audit queries, delays, and — in some cases — a loss of auditor confidence in the quality of your financial controls.
Key Takeaways
- Start year-end preparation in early December: accruals, prepayments, asset reviews, and intercompany reconciliations should all be substantially complete before 31 December.
- Revenue cut-off is the most common source of audit adjustment; confirm that every pound of revenue recognised in December was earned before year-end.
- The going concern assessment is a statutory requirement and must be prepared before the accounts are signed; for investor-backed companies, this requires a rolling 12-month cash flow forecast.
- Related party transactions are a required disclosure; document all transactions with directors, significant shareholders, and connected entities throughout the year, not just at year-end.
- A well-prepared PBC schedule reduces audit time, audit fees, and auditor queries significantly; invest the time to get it right before submission.
- For 31 December year-ends, the Christmas holiday period compresses the closing window; plan around staff availability and send bank confirmation requests before the holiday period.
- Target draft accounts within 10-12 weeks of year-end for investor-backed companies; the board and investors will expect timely reporting.
