Closing a UK Company: Final Accounts and Corporation Tax Planning

Closing a company is a process involving business decisions, creditor responsibilities, tax work, and company-law steps. Applying for strike-off does not erase an unpaid tax bill or turn an incomplete set of records into final accounts. Before deciding on a closure route, establish the company’s financial position and whether it can pay its debts. Insolvency or disputes need appropriate specialist advice rather than a routine filing checklist.

This guide focuses on organising the final accounts and Corporation Tax review for a company considering closure. It does not assume that voluntary strike-off is available or appropriate in every case, or that every payment to a shareholder receives the same tax treatment.

Decide whether the company is closing or becoming dormant

Stopping customer work is not necessarily the same as closing the company. The business may retain assets, receive income, settle old transactions, or remain registered for future use. If the company is to continue as dormant, it still has ongoing responsibilities. HMRC and Companies House use different concepts of dormancy, so a conclusion for one purpose should not be copied into the other without checking.

The official company closure guidance explains that a company left dormant remains registered and still has Companies House filing obligations. Make the intended outcome explicit: pause, cease trading, sell the business, liquidate, or seek strike-off. That decision affects the work required and who should advise. A calendar entry called close company is too broad to manage those separate legal and tax steps.

Prepare a reliable closing balance position

Reconcile bank and payment-platform accounts and list what the company owns and owes. Include customer debts, supplier bills, tax balances, borrowing, stock, equipment, deposits, and expected refunds. A quiet bank account does not establish that everything has been settled. Some liabilities or assets may not appear in the most recent statement, particularly where invoices or tax computations remain outstanding.

Identify uncertain amounts and assign someone to resolve them. For example, confirm whether a customer credit will be refunded, an asset will be sold, or a disputed invoice remains payable. Keep the supporting correspondence and record the outcome. A final accounts exercise should be based on the actual closing transactions and responsibilities, not a decision to remove inconvenient balances so the company appears easier to close.

Establish the final trading and tax timeline

Write down when trading stopped, when employees ceased work, when assets were disposed of, and when final income or costs arose. These events can fall on different dates. Provide the accountant with the facts rather than assuming the day the bank account closes is automatically the end of every accounting or tax period. Ongoing receipts, investment income, or asset transactions may need their own review.

Compare the proposed periods with HMRC’s record and the last accounts filed. If there is a gap or an unusual period length, resolve it before submission. The Company Tax Return should cover the correct accounting period and include the relevant final information. A final period may require more attention than an ordinary year because the business has disposals, adjustments, or loss questions that do not arise in its regular trading cycle.

Complete the final accounts and Company Tax Return

For a company using the strike-off process, GOV.UK’s closing-down instructions require final statutory accounts and a Company Tax Return to HMRC, identifying the final trading position. The guidance says final accounts do not have to be filed with Companies House in that closing process. This should not be interpreted as permission to ignore earlier outstanding obligations or to assume no further review is needed.

The return package still needs the correct accounts, tax computation, CT600 information, and applicable supplementary sections. Use the current supported filing route. The former HMRC joint online filing service closed on 31 March 2026; do not plan a final return around an old tutorial for that service. Confirm commercial software or an adviser-supported route and retain the acknowledgment for the correct company and period.

Review losses, assets and tax adjustments

A final-year loss may create a relief question, but the amount and available claim require review. Do not assume every bookkeeping loss can be refunded or that a loss automatically cancels existing tax. Supply earlier returns, computations, and payment records so the adviser can consider relevant periods and conditions. The final computation should explain the adjustments rather than rely on the fact that the business is shutting down.

Asset disposals can also affect the calculation. Keep sale documents, transfer details, original purchase records, and information about any asset passed to a director or shareholder. A transfer without cash is still a transaction that needs analysis. The business accounts, Corporation Tax, and the recipient’s personal tax may all require consideration. Ask for advice before moving valuable assets, rather than attempting to reconstruct an agreed value after the company has disappeared.

Resolve director and shareholder balances

Prepare a complete director’s loan account and explain outstanding amounts owed by or to the company. Include repayments, personal expenses paid by the company, funds introduced, and any agreed terms. Do not automatically write off balances merely to make the final balance sheet zero. A repayment, waiver, distribution, or other settlement can have different consequences and needs the correct legal and tax treatment.

Plan how surplus money or assets will reach shareholders under the chosen closure route. The tax result depends on the facts and applicable rules, not just the label entered on a bank transfer. A distribution should be considered before the company is struck off. Obtain advice about the appropriate process where the amounts, history, or circumstances make a simple strike-off unsuitable. This is a planning decision, not an administrative afterthought.

A hypothetical closure-workflow example

Imagine Harbourside Design Ltd stops taking new projects in June. The owner wants to apply for strike-off immediately because the bank account contains little cash. The accountant’s review identifies an unpaid customer invoice, a computer still owned by the company, a supplier credit, a director loan balance, and a possible tax repayment. None of these disappears simply because the last client project has ended.

The owner creates a closure schedule assigning a decision and evidence to each item. The customer debt is investigated, the supplier credit is resolved, the asset transfer is reviewed before it occurs, and the director account is reconciled. The tax adviser establishes the correct final period and considers the final return and any permitted claim. The owner also confirms what employees, creditors, and other interested parties must be told under the applicable closure rules.

Only after that work is coordinated does the company proceed with the appropriate route. This example does not decide whether any particular payment is taxable as income or capital, or whether strike-off is legally available. Its practical point is that a closing business needs a transaction-and-responsibility review, not just a low bank balance and a dissolution form. Unresolved refunds and assets can make an apparently quick closure much more difficult later.

Keep tax payment separate from dissolution paperwork

Make a schedule of Corporation Tax and any other outstanding tax obligations, with the correct references and confirmation of payment or agreed resolution. Payroll, VAT, and other registrations may require separate closure steps. Tell the relevant advisers about employees, registrations, and prior notices so they can identify those tasks. Do not assume that filing the final Corporation Tax return automatically closes every other HMRC account.

If a bill cannot be paid, address that fact before relying on voluntary closure. Appropriate debt or insolvency advice may be needed. A strike-off application is not a substitute for settling creditors or following the correct legal process. Keep the correspondence and decisions together, including who is responsible for monitoring objections or follow-up. The director should understand the state of the company’s obligations rather than merely delegate the dissolution form.

Deal with assets and refunds before strike-off

GOV.UK warns that assets left in a dissolved company can pass to the Crown, including money received later such as a tax refund. This is why expected repayments belong on the closure schedule. Check whether a claim is outstanding, where payment will go, and whether the company will still be able to receive it. Closing the bank account before reconciling the tax position can create a practical problem even where the underlying claim is valid.

Do not rush a transfer merely to avoid that problem. The transfer itself may need legal and tax review. Obtain an agreed plan for assets, debts, and bank balances, and retain evidence that it was completed. The important control is a coordinated sequence in which the company receives or settles outstanding items and follows the correct distribution and closure process, rather than leaving value stranded after dissolution.

Preserve records and a post-closure contact plan

Make a final archive of accounts, tax returns, computations, approvals, submission acknowledgments, bank statements, invoices, payroll records, and important correspondence. Record who holds it and how it can be accessed after software subscriptions or adviser engagements end. The company records guidance describes retention responsibilities; closure does not justify immediately deleting the evidence behind the filings.

Agree who will handle later correspondence and retain contact details for relevant advisers. Keep a copy of the closure decisions and the record of how outstanding balances were resolved. A final folder should allow someone unfamiliar with the company to understand what was done, why the chosen route was used, and which liabilities or claims were reviewed. That is more useful than a single screenshot stating that the company no longer appears active.

Frequently asked questions

Does applying for strike-off cancel the tax return?

No. Address the relevant final accounts, return, payment, and other obligations before relying on the closure process. The exact requirements depend on the company and route chosen.

Can I close the bank account before a tax refund arrives?

Review expected receipts before closing it. A repayment or other asset left after dissolution can be difficult to recover. Coordinate the sequence with the adviser rather than assuming a refund can be paid personally instead.

How should I start a closure review?

Prepare the last accounts, current balance schedule, tax correspondence, and a timeline of the cessation. You can contact Litmus to discuss the records needed for a review, while seeking specialist advice where debts, disputes, or insolvency affect the appropriate route.
