UK VAT returns: deadlines and Making Tax Digital

When a VAT Return and its payment are due, what Making Tax Digital asks of you, and what happens if you are late. General information, not advice.

What a VAT Return is

A VAT Return is a form you send to HMRC. It tells HMRC how much VAT you have charged and how much you have paid to other businesses. You usually send one every 3 months. This is your accounting period.

If you are registered for VAT, you must send a return even if you have no VAT to pay or reclaim. GOV.UK says it includes:

You must include VAT on the full value of what you sell. That includes goods or services you take instead of money, for example in part-exchange. If you have not charged the customer any VAT, whatever price you charge is treated as including VAT. HMRC can charge a penalty of up to 100% of any tax understated or over-claimed if you send an inaccurate return.

The deadline

The deadline for sending your return online is usually one calendar month and 7 days after the end of the accounting period. The same date is the deadline for paying. Your return has to be sent, and your payment has to reach HMRC's account, on or before that date, even if it falls on a weekend or a bank holiday. Your VAT online account shows when each return is due and when the payment must clear.

Worked example. For a quarter from 1 July 2026 to 30 September 2026, one calendar month after the end of the quarter takes you to 31 October 2026. Adding 7 days gives a deadline of Saturday 7 November 2026. This matches HMRC's own examples, such as a quarter ending 31 March 2025 being due on 7 May 2025.

If your quarters end in March, June, September and December, the deadlines for quarters ending in 2026 work out like this. Your own period dates may differ, so check them in your VAT online account.

The Annual Accounting Scheme has different deadlines, covered below.

Making Tax Digital for VAT

Making Tax Digital for VAT requires all VAT-registered businesses to keep records digitally and file their VAT Returns using software. GOV.UK says all VAT-registered businesses should now be signed up, and you no longer need to sign up yourself.

The software must be able to keep the records the rules require, prepare your return from those records and send it to HMRC through HMRC's API. You can use one compatible package, or bridging software that connects other software, such as a spreadsheet, to HMRC. GOV.UK has a service to search for compatible software. When you connect it, you grant it authority to access your HMRC data. That authority lasts 18 months, and you can check or withdraw it at any time.

The records you must keep digitally include:

You still keep other records, such as invoices, but they do not have to be digital. If your records are spread across more than one program, the programs must be joined by digital links. Linked spreadsheet cells, file import and export, and API transfers count. HMRC does not count copying and pasting, or typing figures across by hand.

Exemptions

You do not need to follow the Making Tax Digital rules if HMRC is satisfied that:

You ask HMRC for an exemption through VAT general enquiries, and HMRC gives its decision in writing. Apart from a few cases, such as a return after you cancel your registration, only an exempt business can send its return by post or through the VAT online account. HMRC can charge a penalty of up to £400 if you send a paper return and you are not exempt.

Paying

Allow time for the money to reach HMRC. GOV.UK gives these times:

Use your 9-digit VAT registration number, with no spaces, as the payment reference.

Late returns: penalty points

For accounting periods starting on or after 1 January 2023, late returns and late payments have separate penalties. Each return you send late earns a penalty point, including nil returns. When you reach the threshold for your accounting period, you get a £200 penalty, and a further £200 penalty for each late return while you stay at the threshold.

Returns are sentPenalty point threshold
Annually2
Quarterly4
Monthly5

Below the threshold, each point expires on its own. If the return was due on the last day of a month, the point expires on the last day of the month 25 months later. Otherwise it expires on the last day of the month 24 months later.

At the threshold, points only go when you meet two conditions. First, send every return on time for a period of compliance: 12 months (4 returns) if you file quarterly, 24 months if annually, or 6 months if monthly. Second, send every outstanding return for the previous 24 months.

The points system does not apply to your first return after you register, your final return after you cancel your registration, or a one-off return for a period other than a month, quarter or year.

Late payments: penalties and interest

Late payment penalties depend on how late you pay:

HMRC's own example: a company owes £15,000 and pays it on day 51. The first penalty is £450.00 at day 15 plus £450.00 at day 30, which is £900.00. The second penalty runs for 21 days, from day 31 to day 51: £15,000 × 10% × 21 ÷ 365 = £86.30. In total the company pays £986.30 in penalties.

If you cannot pay on time, contact HMRC as soon as you can. A Time to Pay arrangement, a payment plan agreed with HMRC, can mean lower or no late payment penalties. GOV.UK says that to avoid the penalties that start on day 16, you should pay in full or ask for Time to Pay by day 15.

Late payment interest is charged as well, from the first day the payment is overdue until you pay in full. It is simple interest at the Bank of England base rate plus 4%, so the rate moves with the base rate. HMRC's interest rates table listed 7.75% from 9 January 2026 when this page was checked. Check the table for the current rate. Overdue penalties also attract interest.

Correcting a mistake

You can correct errors in returns from the past 4 years in your next return, as long as the net value of the errors is £10,000 or less, or between £10,000 and £50,000 but less than 1% of your total sales. Add the net value to box 1 if it is tax due to HMRC, or to box 4 if it is tax due to you, and keep a note of the error. Larger errors, and any deliberate error, must be reported to HMRC separately.

How the small business schemes change returns

Each scheme has its own turnover limits and conditions. The UK VAT calculator page summarises them, and GOV.UK suggests talking to an accountant or tax adviser about whether one suits you.
