VAT checks before buying a business

VAT checks before a business purchase should cover the transaction structure, registrations, assets and historic compliance. A possible transfer-of-a-going-concern treatment needs specialist assessment of its conditions rather than a label added to the sale agreement.

Reconcile the proposed assets and activity with the draft contract and buyer’s intended use. Identify open enquiries, historic errors and property options early.

Establish what the buyer is acquiring

Distinguish a purchase of shares from a transfer of business assets and activity. List the assets, contracts, premises, employees and trading arrangements included in the proposed deal, together with anything excluded. Identify which entity sells each item and which entity will operate afterwards. A headline purchase price can conceal several different supplies or obligations, so the VAT review needs the transaction structure before it can address the numbers.

A qualifying transfer of a business as a going concern has its own VAT treatment and conditions. It is not a discretionary label that the parties can select simply because it improves cash flow. The buyer's intended operation and the substance of what transfers matter. Property can introduce additional conditions requiring specialist attention before completion. Use the current HMRC guidance to frame that assessment. ^[1]

Request a focused due-diligence pack

Ask for VAT registration details, recent returns, reconciliations, scheme information and explanations of significant adjustments. Include open HMRC correspondence and any known errors that have not been resolved. Compare the information requested with the actual deal: a stock-heavy retailer needs a different transaction sample from a property rental business. The purpose is to identify material uncertainties, not merely to accumulate a large folder of unreviewed statements.

Prepare a question log that links each concern to a document or transaction. Examples include sales coded differently from the stated business model, unexplained repayment returns or inconsistent treatment of deposits. Give the seller a chance to explain the facts before treating a difference as an error. Record the response and any further evidence needed so the buyer can distinguish a resolved query from a matter still affecting risk or price.

Review registration and operating continuity

Describe how the buyer plans to trade immediately after completion. Will it continue the same activity, change the use of the assets or integrate them into an existing business? Record the expected start date, contracting entity and invoicing arrangements. Ask the adviser to assess the registration requirements and effective dates against that plan. Do not assume that the seller's VAT number can simply be printed on the buyer's invoices.

If transferring a registration number is being considered, obtain advice about the implications and the records required. Separate that decision from the wider question of whether the deal qualifies for a particular VAT treatment. Agree how historic records will remain accessible and who will answer later queries. A buyer should understand the responsibilities it is taking on rather than treating a number transfer as an administrative shortcut.

Align the contract and the funding model

Ask the tax adviser and solicitor to review the VAT provisions using the same asset schedule and completion assumptions. The agreement should deal appropriately with the intended treatment and what happens if that treatment is challenged or conditions are not met. Those provisions require legal drafting; an accountant's spreadsheet note is not a substitute. Resolve uncertainty early enough for the buyer to assess its commercial options.

Model the cash required under plausible VAT outcomes without presenting an unconfirmed scenario as settled law. Show the initial funding need, potential recovery restrictions and timing assumptions separately. If the price includes property, deposits or payments before completion, identify those amounts explicitly. This allows lenders and decision-makers to understand where a tax assumption affects liquidity, even when the underlying acquisition remains commercially attractive.

Agree the completion handover

Create a VAT handover schedule covering closing sales, stock records, customer credits, supplier invoices and access to supporting documents. Decide how transactions spanning completion will be identified and who will resolve later queries. Keep the commercial cut-off and the VAT reporting analysis connected but distinct. A transaction allocated to one party economically may still need a specific tax-point assessment before it is entered on a return.

Use VAT on property transactions: questions to raise where land or buildings are part of the acquisition, and VAT compliance review to discuss preparation of the VAT information and review scope. Provide the draft structure, proposed completion date and the main unresolved questions. Where specialist or legal input is required, identify that work explicitly so the acquisition timetable includes enough time for a reasoned conclusion rather than a last-minute assumption.

After completion, compare the first invoices and accounting entries with the agreed structure. Escalate any practical change, such as an asset omitted from transfer or a different operating entity, because it may undermine an assumption used during the pre-completion review.

Illustrative scenario

A buyer acquires equipment, customer contracts and premises from an operating business. The advisers test the proposed VAT treatment against what will actually transfer and how the buyer will operate it.
