There is a misconception doing the rounds online that if your VAT return deadline falls on a weekend, you can submit it on the next working day and still be on time.
That is simply wrong.
For most VAT-registered businesses, the deadline for filing a VAT return and making payment is one calendar month and seven days after the end of the VAT period, and that deadline does not move just because it happens to fall on a Saturday, Sunday or bank holiday. This is not a new rule, and it is not open to interpretation. It has always been the case.
Unfortunately, some third-party websites and online summaries have suggested otherwise, which risks giving businesses and agents a false sense of security. If that advice is followed, the return may be late, payment may be late, and penalties or interest may follow. It is therefore important to be clear: if the due date lands on a non-working day, the due date is still the due date.
What the VAT deadline really means
HMRC’s guidance is clear that the standard online deadline is one calendar month and seven days after the end of the accounting period, with the same date applying to payment in most cases. Recent commentary from professional bodies has also highlighted that there is no automatic extension where that date falls on a weekend or bank holiday. In other words, a deadline of Sunday 7 June is still Sunday 7 June. It does not become Monday 8 June simply because that is the next business day.
Businesses can still submit online at weekends and, depending on the payment method, funds may also be able to reach HMRC outside normal banking hours. If a business cannot file or ensure cleared payment on the due date itself, it should work backwards and act earlier, not later. This is especially important for businesses that leave compliance to the last minute. VAT deadlines are set by law, and casual online advice is no substitute for checking the actual position.
Why businesses and advisers need to get this right
Relying on the wrong deadline can have avoidable consequences. Since the introduction of the VAT penalty points regime, late submissions can lead to points being accrued and, once the relevant threshold is reached, financial penalties can apply. Separate charges may also arise for late payment. Even where the amount involved is modest, repeated errors can create unnecessary cost, administration and stress. For advisers, there is also a professional responsibility to correct misinformation where it appears. If a client, colleague or online source suggests that a VAT return can be filed on the next working day when the deadline falls on a weekend, that should be challenged immediately.
The safer message is straightforward: treat the published due date as fixed and, where necessary, file and pay before it. In practice, this means planning ahead, allowing enough time for authorisation and payment clearance, and avoiding assumptions based on how other deadlines may work. A simple misunderstanding can quickly become a compliance issue, so a cautious and informed approach is always best.
