VAT Return Deadlines 2026/27 UK: Dates, Penalties and What to Do If You Miss One

The UK VAT return deadline is one calendar month and seven days after the end of your VAT accounting period. Filing and payment fall due on the same date, so a quarter ending 30 September 2026 is due by 7 November 2026. Miss it and you can earn a penalty point, late payment penalties and interest.

This guide sets out the deadlines for 2026/27, what the penalties actually cost, and what to do if you have already missed one.

What Is the VAT Return Deadline in the UK?

The standard deadline is one calendar month and seven days after the end of your VAT accounting period. The return must be filed through Making Tax Digital compatible software, and a nil return still has to be submitted. Your first return deadline starts once you are VAT registered, which becomes compulsory when your turnover passes the VAT registration threshold.

Two exceptions. Businesses on the annual accounting scheme file once a year, two months after the period ends. They make interim payments during the year, usually nine monthly or three quarterly, with the balance due alongside the return. Businesses with a VAT liability above £2.3 million make payments on account during the quarter, with a balancing payment due alongside the return.

How HMRC Sets Your VAT Accounting Period

Your accounting period, often called your ‘stagger’, is set when you register. Most businesses are quarterly and fall into one of three staggers: quarters ending March, June, September and December; April, July, October and January; or February, May, August and November. You can check yours on your VAT registration certificate or in your VAT online account.

You can ask HMRC to change your stagger to line up with your financial year end, or to move to monthly returns if you are regularly in a repayment position.

VAT Return Filing Deadline vs VAT Payment Deadline

They fall on the same date but they are two separate obligations with two separate penalty regimes. Filing on time and paying late still triggers a late payment penalty. Paying on time and filing late still costs you a point. If you pay by direct debit, you must still file by the deadline, and HMRC then collects the money three working days later.

We recommend establishing a direct debit to pay a business’s VAT liability. This removes most of the risk of paying late, but it does not replace filing on time.

VAT Return Due Dates 2026/27 by Quarter End

To find your date, take the last day of the period, add one calendar month, then add seven days. A period ending 28 February is due 7 April.

Annual accounting year ended 31 March 2026: due 31 May 2026.

How to Calculate Your VAT Return Due Date

Take the last day of the period, add one calendar month, then add seven days. February works the same way, so a period ending 28 February is due 7 April.

The filing deadline does not move for weekends or bank holidays. The practical deadline for payment does, which is covered next.

VAT Payment Deadline: When Must You Pay HMRC?

Cleared funds must reach HMRC by the same date the return is due. It is the date the money arrives that counts, not the date you press send.

That makes the payment method part of the deadline. Faster Payments usually arrive the same day or the next, while Bacs and standing orders take three working days. If the deadline falls on a weekend or bank holiday and you are not using Faster Payments, the money needs to clear on the last working day before it. For example, 7 November 2026 is a Saturday, so a Bacs payment for that date needs to clear by Friday 6 November.

Direct debit is the safest route for most businesses. HMRC takes the correct amount three working days after the deadline, so paying late becomes hard to do by accident.

VAT Return Penalties: What Happens If You Miss the Deadline?

Since January 2023 there have been two separate systems: penalty points for late filing, and penalties charged as a % of the VAT, plus interest, for late payment. One late return that is also paid late attracts both.

Late Submission Penalty Points

Each late return earns one point. You get a £200 penalty when you reach the threshold, and a further £200 for every late return after that.

The threshold depends on how often you file. A nil return filed late also earns a point.

If you stay below the threshold, each point expires automatically after about two years. Once you reach the threshold, points do not expire. To reset to zero you need to file every return on time for the compliance period shown above, and all returns for the previous 24 months must have been submitted.

Late Payment Penalties, Interest and Appeals

Pay within 15 days of the deadline and there is no penalty, although interest still runs from the day after the due date. After that:

• Day 15: a first penalty of 3% of the VAT still outstanding
• Day 30: a further 3% of whatever is still outstanding
• Day 31 onwards: a second penalty accruing daily at the equivalent of 10% a year until the balance is cleared

Late payment interest runs on top, at the Bank of England base rate plus 4%. That is currently 7.75%, based on a base rate of 3.75% (last checked October 2026). The rate changes whenever the base rate does.

Penalties can be appealed within 30 days where you have a reasonable excuse, meaning something outside your control rather than a cash flow problem or a forgotten deadline.

Missed Your VAT Return Deadline? Here’s What to Do Next

1. File the return immediately, even if you cannot pay. The two penalties are separate, and filing stops the points clock.
2. Pay what you can within 15 days to avoid the first penalty, or reduce it by paying part of the balance.
3. If you cannot pay in full, ask HMRC for a Time to Pay arrangement before day 15. Asking early stops further penalties building, provided you keep to the instalments.
4. Check whether you have a reasonable excuse worth appealing, such as serious illness or an HMRC software failure.
5. Tell us. The sooner we know, the more options there are.

How to Avoid Missing Future VAT Return Deadlines

• Set up a direct debit. It removes the payment deadline as a risk for most businesses.
• Turn on email reminders in your VAT online account.
• Keep the bookkeeping current rather than doing a quarter’s worth in the final week.
• Put the VAT aside as it is collected, ideally in a separate account.
• Agree a date each quarter for records to reach us, a fortnight before the deadline.

Common VAT Return Mistakes That Lead to Penalties

• Not filing a nil return. No sales in the quarter does not mean no return, and the point is charged all the same.
• Reclaiming VAT without a valid VAT invoice, which HMRC can disallow.
• Getting the domestic reverse charge or postponed VAT accounting wrong, which distorts the figures in both directions.
• Filing from bookkeeping that has not been reconciled, so the return has to be corrected later.
• Assuming a changed stagger or a new registration has been picked up automatically. The first return under a new period is the one most often missed.

Conclusion

The deadline itself is simple: one month and seven days after the period ends, for both the return and the money. The cost of missing it is what has changed. Points accumulate quietly in the background, and late payment carries 3%, then another 3%, then a daily charge and interest at 7.75% on top. Keep the bookkeeping current, pay by direct debit, and the deadline takes care of itself.
