After the summer VAT cut: a records check for affected businesses
HMRC says businesses that used the temporary summer VAT rate should check their tills, software and VAT records after the rate returned to 20%.
What changed after 1 September
HMRC’s 17 September 2026 Agent Update says the temporary reduced VAT rate ended on 1 September 2026. Relevant sales from 2 September should use the standard 20% rate. The temporary measure covered specified children’s meals, children’s or family tickets and admission to certain family attractions; it did not make every family-facing or hospitality sale eligible.
The date matters for businesses whose tills, booking systems or accounting routines were configured for the summer measure. A customer-facing price, an invoice date and an admission date may not tell the same story, so keep the question of eligibility separate from the later check that the correct rate was recorded.
Start with the systems that set the rate
Check tills, point-of-sale settings, booking platforms, accounting software and VAT-code tables. Compare the effective date in each system with the first transactions after 1 September. Keep a dated note of what was changed and who checked it. This is a TaxMirror preparation suggestion, not an additional HMRC requirement.
Include any separate system used for online bookings, advance sales, refunds or ticket amendments. If more than one site or sales channel was involved, record which locations were checked and whether they used the same rate table. That makes a later exception easier to trace without treating every exception as a tax error.
Reconcile transactions after the change
Review sales from 2 September onward for the affected categories. Match a sample of receipts and invoices to the VAT code used in the ledger, then investigate exceptions such as refunds, voids, amended bookings or bundled sales. Compare gross totals with the relevant till or booking report so that a rate change is not confused with a change in sales volume.
Separate the VAT review from the question of whether a sale qualified for the temporary scheme in the first place. For admission and advance-payment questions, use the current HMRC VAT guidance for the specific facts rather than assuming that the transaction date alone decides the rate. Where a package contains several elements, document the basis for the treatment instead of applying the old summer code to the whole receipt automatically.
Keep the evidence together
Retain the relevant reports, correction notes and reconciliations with the VAT records for the period. If an error is found, follow the normal VAT correction process applicable to the size and nature of the error. Note the affected dates, supplies, VAT codes and any correction already made so the working papers explain the movement from the original return figures.
Do not assume every family-facing sale qualified for the temporary rate, and do not apply a blanket refund or adjustment without checking the underlying supply and current HMRC rules. If the records do not establish the treatment, flag the uncertainty for the person responsible for the VAT return and preserve the source documents used to resolve it.
