Step 1: Understand why you were selected

Inspections can be random, but many follow risk signals — a repayment claim, a sudden change in VAT figures, a late return, or being in a sector HMRC watches. Knowing the likely focus helps you prepare the right records.

Step 2: Assemble your records

Have your VAT account, sales and purchase records, VAT invoices, bank statements and returns ready and reconciled. Under Making Tax Digital these are digital, which makes producing them straightforward if your bookkeeping is current.

Step 3: Reconcile before they arrive

Run your own check: do the returns reconcile to the ledgers and the bank? Are all reclaimed input VAT amounts backed by valid invoices? Finding and correcting an error yourself first — see correcting a VAT error — is far cheaper than HMRC finding it.

Step 4: Handle the visit calmly

Be cooperative, answer questions factually, and if you do not know an answer, say you will confirm rather than guess. Consider having your accountant present. Most inspections end with no issue or a minor adjustment.

Step 5: Deal with any assessment

If HMRC assesses additional VAT, check it, dispute it if wrong, and if it is right, budget for the payment. A short facility can cover an unexpected assessment while you keep trading.
