VAT returns: common mistakes (UK) and how Coventry businesses can avoid them

VAT can be straightforward when your records are clean — but small errors can lead to penalties, cash‑flow surprises or time‑consuming HMRC queries. Below are common VAT return mistakes we see and practical ways to avoid them.

1) Registering late (or registering when you don’t need to)

Missing the VAT threshold or misunderstanding what counts as taxable turnover is a frequent issue. Track rolling 12‑month turnover and review it monthly.

2) Incorrect VAT treatment on expenses

• Claiming VAT where there is no valid VAT invoice

• Treating exempt items as zero‑rated (they’re different)

• Claiming VAT on entertainment (often blocked)

• Not applying the correct rules for fuel/mileage

3) Mixing personal and business transactions

When transactions are mixed, VAT coding becomes unreliable. Use a dedicated business account and keep clear references.

4) Not reconciling before submitting

Submitting without reconciling bank and sales ledgers increases the chance of missing income or duplicating expenses. A simple monthly reconciliation routine reduces errors dramatically.

5) Reverse charge and overseas services confusion

If you buy certain services from overseas suppliers, the reverse charge may apply. This is an area where getting advice before filing can save a lot of rework.

6) Flat Rate Scheme mistakes

If you use the Flat Rate Scheme, you generally can’t reclaim VAT on most purchases (with limited exceptions). Make sure your bookkeeping system reflects the scheme correctly.

7) Poor record keeping

VAT returns are only as good as the underlying records. Keep digital copies of invoices/receipts and maintain consistent categories.
