Six weeks before year end, the same picture plays out in UK finance teams. The ledger is still open, VAT needs reconciling, payroll has loose ends, and nobody wants to guess the Corporation Tax number. That guesswork is expensive. A profit figure left too high lands tax on money the business never really earned, and a sloppy accrual can weaken a lender conversation or slow a facility renewal.
A proper year end accounts checklist is not admin for the sake of admin. It protects cash, tax efficiency, and credibility. It also keeps the close aligned to the statutory timetable, because private limited companies must send annual accounts to Companies House within 9 months of the accounting reference date, and the Corporation Tax payment is due 9 months and 1 day after the end of the accounting period, while most company accounts are filed 6 months after year end for public inspection CPA Charge. In practice, that means the work has to be done early, cleanly, and with source evidence.
The accountancy question is simple. What must be checked now so the numbers are defensible later? For UK SMEs, the answer sits in cash, stock, payroll, tax, and disclosures. Get those right, and the close becomes a control exercise. Get them wrong, and year end turns into a rescue job.
1. Bank and Cash Reconciliation
Cash is the first test. If the bank does not agree to the ledger, the year end close is not ready, full stop. A year end accounts checklist should start here because cash tells directors, lenders, and accountants whether the business can meet its bills, not just whether the profit line looks tidy.
A manufacturer with around £3 million turnover once caught a duplicate supplier payment because the bank reconciliation was done properly before sign-off. That saved cash and stopped a preventable balance sheet error from flowing into the final numbers. A logistics business also found receipts that had been coded badly, which changed the revenue picture before the accounts went out.
What to do now
- Match every bank account to the ledger: Include main accounts, petty cash, and cash equivalents. Any difference needs a clear explanation and evidence.
- Deal with old items first: Anything sitting for more than 30 days should be investigated straight away. Old reconciling items usually point to a coding error, a duplicated entry, or a missed transaction.
- Separate duties: The person who handles cash should not be the same person who signs off the reconciliation. That protects control and credibility.
- Keep the audit trail clean: Save statements, screenshots, and notes for every reconciling item.
- Use software, then check it properly: Cloud accounting platforms can reduce manual matching, but they do not replace judgement. A human review still has to confirm what is real, what is timing, and what is wrong.
For a step-by-step guide to reconciling bank statements, use a process that starts with the bank feed, clears known timing differences, and leaves no unexplained balance behind. If the cash balance is wrong, the board sees weak control, the lender sees risk, and the tax return starts from the wrong base.
Practical rule: if the bank rec is not clean, the year end accounts are not ready.
2. Inventory and Stock Valuation
Stock is where profit gets distorted fast. For manufacturers, distributors, and retailers, inventory is often a major balance sheet asset, so any error feeds straight into gross profit and Corporation Tax. The rule is simple, stock has to be valued at the lower of cost or net realisable value, and the count has to be reliable.
A Midlands engineering distributor found slow-moving components worth £67,000 during stock take and wrote them off before accounts were finalised. That did two things. It stopped overstated profit from leaking into the tax computation, and it freed warehouse space for items that move. A food and beverage wholesaler also found damaged stock through proper net realisable value testing, which is exactly what a serious year end accounts checklist should catch.
Tight stock control beats year end panic
Plan the count early. Four to six weeks before year end is the right window, because there is still time to price items, review write-offs, and challenge anything that looks stale. Monthly review of aged stock reports also matters, because slow-movers become write-downs long before the count date.
Use a structured count sheet, barcode scanning if available, and clear cut-off rules for goods in transit. The count should distinguish between items received before year end and items received after it. If those lines blur, the inventory figure becomes guesswork.
Practical rule: if the warehouse team cannot trace the item, the accountant should not carry it at full value.
A high-quality stock review also protects credibility with funders. If the stock figure is inflated, working capital looks stronger than it is, and that can distort borrowing conversations. A clean stock valuation shows management knows what it owns, what it can sell, and what should already have been written down.
3. Accruals and Prepayments Review
Accruals are the costs already earned by suppliers but not yet invoiced. Prepayments are the opposite, money paid in advance for future benefit. Year end accounts go wrong when those two are treated casually, because profit moves in the wrong period and liabilities disappear from view.
A £4 million turnover tech start-up once failed to accrue professional fees for audit, legal, and recruitment work, which overstated profit by £32,000 before the accountant caught it. A construction subcontractor also forgot to accrue £18,000 for materials invoiced after year end, and that created a post-audit adjustment that damaged lender confidence. That is the sort of avoidable problem a disciplined close should remove.
Review the cost side properly
- Ask suppliers for outstanding invoices: Do this two to three weeks before year end, not after the books are nearly closed.
- Check services delivered but not invoiced: Utilities, professional fees, contractor work, software subscriptions, and insurance are the usual misses.
- Reverse stale prior-year prepayments: If an item was not invoiced in the new year as expected, the old prepayment may need reversing.
- Document the estimate basis: Write down why the amount was accrued, whether it is based on contract terms, prior invoices, or usage.
A useful year end accounts checklist never treats accruals as a tidy-up job. It treats them as a control on profit quality. If the company wants its figures to support funding, bonus planning, or dividend decisions, the accruals schedule has to be credible.
4. Fixed Asset Register Review and Depreciation
Fixed assets are where balance sheet discipline either shows up or falls apart. Plant, machinery, vehicles, IT equipment, and leasehold improvements must all be tracked, because the register drives depreciation, tax treatment, and disposal accounting. UK SMEs often leave this too late, then wonder why the asset base and the ledger no longer agree.
A manufacturing business once failed to record £45,000 of plant disposals in its fixed asset register. That overstated net book value and distorted depreciation. A logistics company also capitalised £12,000 of vehicle maintenance that should have gone through repairs. Both errors are classic year end mistakes, and both are easy to avoid with a proper review.
Keep the asset story clean
Maintain a live register in spreadsheet form or inside cloud accounting software. Update it monthly, not just once a year. A clear capitalisation policy helps too, because teams need a rule on what gets capitalised and what gets expensed.
- Verify additions: Challenge anything unusual or high-value.
- Check disposals: Items sold, scrapped, or written off need removing from the register.
- Revisit depreciation rates: Only change useful lives if business circumstances have changed in a real way.
- Physically confirm major assets: Vehicles, plant, and IT kit should be checked at least annually.
The year end accounts checklist should also join up with R&D and capital allowances planning. If a business misclassifies assets, it can lose tax relief or create inconsistent treatment across years. That is a cash problem as much as an accounting one.
Practical rule: if the board can't explain what changed in the asset base, the register is probably not current enough.
5. Trade Receivables and Bad Debt Review
Debtors are not cash until they are cash. An aged receivables review tells the finance director which customers are paying, which are drifting, and which invoices are probably never coming in. That matters for profit, working capital, and the strength of the balance sheet.
A £5 million turnover B2B services company identified £28,000 of debt from a customer that had become insolvent. Writing it off before year end removed false comfort from the numbers and stopped future surprises. A SaaS start-up also found that a significant slice of invoices over 90 days was unlikely to be collected, which forced a bad debt provision and better credit control.
Make overdue debt impossible to ignore
Review the aged receivables report every month. A year end-only review is too late, because the relationship issue has already become a cash issue. Customers over 90 days overdue need direct contact, not a polite shrug.
A strong checklist should include:
- Credit control discipline: Keep payment terms consistent and enforce them.
- Post year-end cash receipts: If payment lands after the balance sheet date but before accounts are finished, that is strong evidence on recoverability.
- Bad debt provisioning consistency: Keep the method stable unless something material changes.
- Dispute tracking: Separate a genuine dispute from a slow payer pretending to dispute.
The credibility outcome is simple. Clean debtors give lenders confidence in reported working capital. Messy debtors tell them the business does not know who owes what. That is why a serious year end accounts checklist never leaves receivables to the final week.
6. Payroll and Employment Liabilities
A payroll close that looks tidy can still hide a real problem. Bonuses approved late, holiday pay earned but unpaid, and PAYE cut-offs all belong in year-end liabilities. If they are missing, profit is overstated and the balance sheet is wrong.
A £6 million turnover recruitment business forgot to accrue £18,000 in bonuses that had been approved but not paid. A manufacturing company with 35 staff missed £22,000 of holiday pay liability, which understated creditors and overstated profit until the accountant flagged it. Those errors damage credibility fast, because directors start to doubt the numbers they are relying on.
Tie payroll to the ledger
Payroll should stay tied to the general ledger. Reconcile the monthly payroll totals to the books, then check that PAYE, National Insurance, pension contributions, and any other employment liabilities are recorded correctly.
Payroll systems support better reporting, but the finance team still has to inspect the outputs. Approved bonuses, redundancy costs, settlements, and unpaid holiday all need written confirmation before they go into the accounts. Salary sacrifice changes also need a proper review, because they affect payroll planning, reported costs, and the cash the business keeps. Use Understand how salary sacrifice budget changes affect payroll planning to keep that review disciplined.
Practical rule: if management has said the bonus is happening, the liability belongs in year end accounts even if cash leaves later.
This item also protects credibility with HMRC. PAYE is a legal liability, not a number to tidy up later. Late reporting or underpayment creates avoidable pain, and a weak payroll close can spill into the Corporation Tax calculation because the expense base is wrong.
7. Tax Provisions and Corporation Tax Calculation
The tax provision is where the accounts turn into a cash conversation. A sensible year end accounts checklist calculates the Corporation Tax estimate early enough for directors to plan funding, dividends, and reserves. It also forces the team to separate accounting profit from taxable profit.
A £4 million turnover software company once missed £85,000 of R&D tax credit entitlement when calculating its tax provision, which overstated tax and hid a cash benefit the business should have been planning for. A manufacturing business also treated a £45,000 equipment repair as capital, which inflated the tax provision by £11,250 at 25%. That is not a minor slip. That is money left in the wrong place.
Get the computation right first time
Start with a proper tax computation template. List the adjustments one by one, then confirm the tax treatment of each item, including depreciation, accruals, provisions, entertaining, donations, and capital allowances.
If the business has R&D spend, the claim should be worked in parallel rather than assumed for later. Waiting pushes the provision off target and weakens cash planning. Liaising with the accountant 6 to 8 weeks before year end is the right move, because tax issues need time, not optimism.
Use tax strategies for growing companies
The strategic point is plain. A tax provision is not just a compliance entry. It shows how much cash the business may need to set aside, and it helps directors avoid discovering the tax bill after the funds have already been spent.
8. VAT Position and Compliance Review
VAT year end work is about evidence, consistency, and cut-off. For a VAT-registered company, the return has to be right, on time, and tied back to the VAT control account in the ledger. That protects cash, avoids penalties, and stops the board filing accounts that do not agree with the VAT position.
The job is to make sure the VAT balance in the accounts matches the return and that the books can prove it. HMRC's Making Tax Digital rules changed the baseline for VAT-registered businesses with taxable turnover above the VAT threshold, because from April 2019 they had to keep digital VAT records and use compatible software, and by April 2022 the digital filing rule applied to all VAT-registered businesses The Access Group. That puts document control and bank-to-VAT checks into year end discipline, where they belong.
A £2 million turnover marketing agency failed to claim input tax on a £30,000 software licence because the invoice was missing. Reclaiming that input tax created a £6,000 refund. A logistics business also treated some supply chain services as exempt when they were not, which distorted output tax and input tax by £12,000. For practical guidance on VAT accounting controls, see Review VAT accounting support.
Treat VAT as a control account, not a filing afterthought
Reconcile the VAT account monthly. Keep invoice and receipt support for at least six years. Review unusual transactions before they hit the return, especially large software purchases, mixed-use costs, or services with uncertain treatment. If the treatment is unclear, fix it before the filing deadline, because late corrections drain time, weaken credibility, and create avoidable cash pressure.

A clean VAT balance tells HMRC and the board the books are controlled. A dirty one usually means the rest of the close is weaker than it looks.
9. Related-Party Transactions and Consolidation Review
Related-party transactions are where credibility gets tested quickly. If the company trades with a parent, subsidiary, associate, director, or connected person, the year end accounts must show that those dealings were documented, reasonable, and at arm's length. If the business is part of a group, consolidation also has to remove internal profits and balances.
A £10 million turnover family business paid the founder's spouse £80,000 a year as a consultant without documented duties or deliverables. That was challenged at audit and disallowed for tax purposes. A group of three trading companies also failed to eliminate a £145,000 intra-group profit on goods sold between entities, which overstated consolidated profit until the error was caught.
Put the paper trail in place
Build a related-party register at year end. List every material transaction, explain the commercial purpose, and document why the pricing is fair. Intercompany management fees, loan interest, and shared costs all need support.
- Document the rationale: Record why the charge exists and how the amount was set.
- Review prior disclosures: Update for new relationships or changed terms.
- Prepare elimination schedules: In group accounts, intra-group balances and profits have to come out.
- Keep transfer pricing logic clear: If prices differ from market terms, the file must explain why.
This is not just a disclosure exercise. It protects tax treatment and stops the group reporting pack from telling a false story. A sharp year end accounts checklist always asks whether the group looks like the group it says it is.
10. Contingent Liabilities, Legal Claims and Subsequent Events
The final check is judgment. Year end accounts need to reflect known risks, not pretend they do not exist. Legal claims, warranty issues, environmental problems, and other obligations from past events all need to be assessed properly. So do events after year end but before accounts are signed.
A manufacturing business defending a product liability claim valued at £120,000 failed to accrue or disclose it, and the accounts had to be restated at audit. A logistics company facing a contract dispute over £85,000 in disputed charges disclosed it as a contingent liability, which gave users a transparent picture. A £3.5 million turnover business also received a large customer order and deposit of £180,000 in January after year end, which helped validate the receivable estimate. Another manufacturing company agreed to acquire a competitor's assets for £400,000 in February, and that was disclosed as a non-adjusting event.
Close with a proper post-year-end review
Request written confirmation from solicitors on any pending or threatened claims. Speak to operations leaders directly, because they know about warranty disputes, service failures, and customer complaints before the board does. Review bank statements, customer correspondence, and purchase orders from the first two to three weeks of the new financial year.
Practical rule: if management knows about it before signing, the accounts team should already have assessed whether it changes the numbers or the note disclosures.
A good checklist separates probable, possible, and remote risks, then documents that judgment clearly. That protects the audit trail and stops last-minute surprises from undermining trust in the signed accounts.

From Checklist to Confident Filing
The best way to run a year end accounts checklist is in sequence, not as a pile of tasks. Start six weeks before year end with bank, stock, payroll, and receivables. That gives the finance team time to fix errors while source documents are still fresh. Move into accruals, prepayments, assets, VAT, and tax provision work before the final close window. Then finish with related-party disclosures, contingent liabilities, and post-year-end review before the accounts are signed and filed.
That sequence matters because the filing timetable is fixed, not negotiable. Private limited companies have 9 months from the accounting reference date to file annual accounts at Companies House, and Corporation Tax is due 9 months and 1 day after the accounting period ends CPA Charge. Companies House also records that most company accounts are filed 6 months after year end for public inspection, which is why checklist-led preparation has to happen early enough to leave space for review, adjustment, and sign-off CPA Charge. If the work is left too late, the business is not just risking lateness. It is risking penalties, HMRC interest, and poor-quality tax computations.
The commercial outcome is the reason this process exists. Clean bank recs protect liquidity visibility. Accurate stock and fixed assets protect profit and tax. Tight payroll, VAT, and Corporation Tax work protect cash. Proper disclosures protect credibility with lenders, auditors, and directors. That is what strong year end accounts look like in a £1 million to £15 million turnover business.
FAQs
What is included in a year end accounts checklist?
A solid checklist covers bank reconciliations, stock valuation, accruals and prepayments, fixed assets, receivables, payroll, tax provisions, VAT, related-party transactions, and post-year-end events. It is built to prove the numbers, not just file the paperwork.
When should a UK company start year end accounts preparation?
Six weeks before year end is the right starting point for a scaling SME. That gives enough time to clear reconciliations, chase missing invoices, review stock, and settle tax estimates before the accounts have to be finalised.
What is the biggest mistake in year end accounts?
Leaving reconciliation until the final week is the biggest mistake. It leads to rushed estimates, missed accruals, weak support, and avoidable revisions after the draft accounts have already been seen by lenders or directors.
Why does VAT matter so much in year end accounts?
VAT is a control account as much as a filing obligation. If the VAT balance does not agree to returns and source documents, the accounts may be wrong and the business may miss reclaimable input tax or overstate liabilities.
How do year end accounts help cash flow?
They show the position on debtors, stock, payroll liabilities, tax, and creditor timing. That gives directors a better basis for funding, dividend, and reserve decisions before cash gets committed elsewhere.
