When is the VAT return deadline in August 2026?
The VAT return deadline in August 2026 is 7 August. That's the date for VAT-registered businesses whose accounting quarter ended on 30 June 2026.
By 7 August 2026 you need to do two things: File your return and pay any VAT you owe. Both fall on the same day, so treat them as a single deadline.
Not every business works to the same quarter. When you register for VAT, HMRC assigns you to a stagger group – this determines which three months your VAT quarters cover. You can check your stagger group when you sign in to your HMRC account. If the deadline falls on a weekend or bank holiday, allow enough time for your payment to reach HMRC by the last working day before it. If you pay by direct debit, HMRC collects the amount automatically, about three working days after the deadline. You can confirm your own dates when you sign in to submit your VAT return.
VAT return dates: the full 2026 quarterly calendar
Standard quarterly VAT returns in 2026 are due on 7 May, 7 August, and 7 November, with the next quarter due on 7 February 2027. You can work out your own date with HMRC's VAT payment deadline calculator. Each deadline covers the quarter that ended just over a month earlier.
Here's how the most common quarterly stagger maps out across the year:
- Quarter ending 31 March 2026: File and pay by 7 May 2026.
- Quarter ending 30 June 2026: File and pay by 7 August 2026.
- Quarter ending 30 September 2026: File and pay by 7 November 2026.
- Quarter ending 31 December 2026: File and pay by 7 February 2027.
These dates follow one of three quarterly staggers. The other two end their quarters a month or two earlier, so your own dates may sit slightly ahead of the calendar above. Businesses that file monthly, or that use the annual accounting scheme, work to a different timetable again.
How your VAT deadline is worked out
Your VAT deadline is one calendar month and seven days after your accounting period ends. That single date covers both your return and your payment.
Take the quarter ending 30 June 2026 as a worked example. Count forward to the end of the calendar month after your quarter ends (31 July). Then add 7 days to reach 7 August 2026. The same sum works for every standard period, so you can plan the whole year from your quarter-end dates.
Two arrangements follow their own timetable rather than the one calendar month and seven days rule:
- Payments on account: Larger businesses (typically with over £1.7m annual turnover) make advance payments through the quarter, each with its own due date. This doesn't apply to most small businesses.
- Annual accounting scheme: You file one return a year and pay in instalments across it.
If you use the annual accounting scheme, your dates differ, so check HMRC's return and payment deadlines for that scheme.
How to submit and pay your VAT on time
You file your VAT return through compatible software and pay HMRC separately, so give both parts enough time. Line them up well before 7 August rather than on the day itself.
Follow these steps to stay ahead of the deadline:
- Confirm your VAT period and deadline so you know the exact date you're working towards.
- Keep your VAT records digitally throughout the quarter so the figures are ready when you file.
- File your return using Making Tax Digital-compatible software, which sends the return straight to HMRC. Making Tax Digital is HMRC's requirement that all VAT returns are filed through compatible accounting software (not on paper or manually). Your software connects directly to HMRC, so the return is sent automatically.
- Choose how to pay, whether that's direct debit, bank transfer, or a debit or corporate card.
- Allow time for the payment to clear, because a bank transfer needs to reach HMRC by the deadline, while a direct debit is collected around three working days after it.
Getting your records in order early gives you room to check the numbers before anything is submitted. It also avoids a last-minute scramble if a payment takes longer to clear than you expect.
What happens if you miss the VAT deadline?
Miss the deadline and you could pick up a penalty point for filing late, plus separate penalties and interest for paying late. HMRC treats late filing and late payment as two different things.
Late returns work on a points system. You get one point each time you file late, even if there's no VAT to pay. Once a business that files quarterly reaches four points, HMRC charges a £200 penalty, then a further £200 for every late return after that. You can read the detail on penalty points for late VAT returns.
Late payment penalties build up in stages:
- First 15 days: no penalty, although interest starts to build straight away
- Day 15: a first penalty of 3% of the VAT still unpaid
- Day 30: a further 3% of whatever remains outstanding
- From day 31: a second penalty accrues daily at an annual rate of 10% on the balance
On top of these, HMRC charges late payment interest at the Bank of England base rate plus 4%. For the full breakdown, see how late payment penalties are calculated.

FAQs on VAT return deadlines
Here are quick answers to the questions small business owners ask most about VAT deadlines.
When is my VAT payment due?
Your payment is due on the same day as your return, one calendar month and seven days after your period ends. If you pay by direct debit, leave the amount in your account, as HMRC collects it a few working days later.
What happens if I file my VAT return late?
You get one penalty point per late return, and a nil return still needs filing on time to avoid a point. Reach four points as a quarterly filer and a £200 penalty follows.
Do monthly VAT filers have a different deadline?
Yes. Monthly filers submit 12 returns a year, each due one calendar month and seven days after the end of that month, so the August window applies to July's period rather than a whole quarter.
