VAT return
A periodic report submitted to HMRC that summarises the VAT a business has charged on sales (output tax) and paid on purchases (input tax), with the difference either payable to HMRC or reclaimable from them.
A VAT return is the formal declaration a VAT-registered business sends to HMRC — usually every quarter — showing how much VAT it collected from customers and how much it paid to suppliers. The difference is the net liability. If output tax exceeds input tax, you pay the difference. If input tax exceeds output tax (common in early-stage businesses buying more than they sell), HMRC refunds the balance.
Since April 2022, almost every VAT-registered business in the UK must file under Making Tax Digital (MTD), meaning returns are submitted via compatible software — Xero included — rather than through HMRC’s online portal directly. Xero compiles the nine required VAT return boxes automatically from posted transactions, provided each transaction has been correctly coded to a VAT rate.
The reconciliation link
A clean VAT return depends entirely on clean bookkeeping. If bank lines sit unreconciled at the end of the quarter, or transactions are coded to the wrong VAT rate, the figures Xero calculates will be wrong. A common pre-submission check is to reconcile the VAT control account: the balance in the nominal ledger should match the net amount Xero is about to submit. A £200 discrepancy — perhaps a supplier invoice posted with 20% VAT that should have been exempt — is far easier to trace before submission than after.
