VAT return deadlines and penalties

The basic deadline

For almost every VAT registered business the rule is the same. One calendar month and 7 days after the end of the VAT period, both the return and the money must be with HMRC.

A quarter ending 31 March gives a deadline of 7 May. A quarter ending 30 June gives 7 August. A quarter ending 30 September gives 7 November. A quarter ending 31 December gives 7 February.

The deadline does not move for weekends or bank holidays. If 7 May falls on a Sunday, the deadline is still 7 May, which means in practice the money has to be sent by the Friday. This catches out more businesses than any other feature of the system.

The payment must arrive, not just be sent

This distinction matters and it costs businesses real money. HMRC counts the date the funds arrive in its account, not the date you pressed the button.

Faster Payments usually clear the same day or the next day, so they are safe. Bacs takes 3 working days. A cheque, if you still use one, needs to be with HMRC by the deadline and is at the mercy of the post. Direct Debit under Making Tax Digital is collected automatically 3 working days after the deadline, which is the one arrangement where money genuinely leaves later than the deadline without any consequence.

For anybody who tends to leave things late, the Direct Debit is worth setting up for that reason alone. It removes the timing risk entirely, provided the funds are in the account when HMRC collects.

Which quarter you are on

When you register for VAT you are allocated a stagger group, which determines your quarter ends. Stagger 1 ends in March, June, September and December. Stagger 2 ends in April, July, October and January. Stagger 3 ends in May, August, November and February.

You can ask HMRC to change your stagger, and it is worth doing if your quarter end lands awkwardly against your busiest trading period or your accounting year end. Aligning the VAT quarter with your financial year end makes the year end accounts noticeably cleaner.

Some businesses file monthly instead, which is usually chosen by those in a repayment position, such as exporters or builders working on zero rated new build. Monthly filing means monthly refunds rather than waiting a quarter for the cash.

The points system for late returns

Until 2023 a late VAT return triggered the default surcharge, which could be brutally expensive for a first offence. That has gone, replaced by a points system that behaves more like a driving licence.

Each late return earns one point. Nothing is charged until you reach the threshold, which is 4 points for quarterly filers, 5 for monthly filers and 2 for annual filers. Once you hit the threshold you get a £200 penalty, and a further £200 for every subsequent late return while you remain at the threshold.

So a quarterly filer who is late once, twice or three times pays nothing in penalties. The fourth late return costs £200, and every late return after that costs another £200 until the points are cleared.

Points do expire. Individual points drop off after 24 months if you have not reached the threshold. Once you are at the threshold, clearing the points requires both a period of compliance, which is 12 months for quarterly filers, and having filed all returns due in the previous 24 months. Only then does the slate reset to zero.

The important nuance is that a nil return and a repayment return both count. Being owed money by HMRC does not excuse a late submission, and a business in a permanent repayment position can quietly accumulate points and then be surprised by a penalty.

Late payment penalties are completely separate

Filing on time and paying on time are two different obligations. You can be punctual with one and late with the other, and the consequences run in parallel.

Nothing at all is charged for the first 15 days. This is deliberate, and it means a payment that slips by a few days because of a banking issue or a short term cash gap costs you nothing beyond interest.

At day 15 a first penalty of 3% of the amount still outstanding is charged. If the amount is still outstanding at day 30, a further 3% of the amount outstanding at that point is added. From day 31 onwards a second penalty accrues daily at an annual rate of 10% on the balance until it is paid.

On an unpaid VAT bill of £20,000, that is £600 at day 15, another £600 at day 30, and then roughly £5.50 a day thereafter. Left for a full year the second penalty alone would approach £2,000.

The 15 day rule is a genuine safety net

The design of this system rewards businesses that act quickly. If you cannot pay on the deadline, you have a fortnight in which nothing is charged, and within that fortnight you can either find the money or agree a Time to Pay arrangement.

Crucially, agreeing a Time to Pay arrangement, or even just proposing one that HMRC later accepts, stops the penalty clock from the date you asked. So a business that contacts HMRC on day 10 and agrees instalments avoids both the 3% charges entirely, even though the money will be paid over several months.

A business that says nothing and hopes for the best pays 6% within a month. The difference is a phone call.

Interest on top

Separately from penalties, late payment interest runs from the day after the deadline until the day the money is paid, at a rate linked to the Bank of England base rate. Interest is charged even where a Time to Pay arrangement is in place, so an arrangement stops the penalties but not the interest.

Where HMRC owes you money and is late repaying it, repayment interest runs in your favour, though at a lower rate.

Making Tax Digital is now compulsory

Every VAT registered business must keep digital records and file through compatible software. Typing figures into the HMRC website by hand has not been an option for several years, and there is no longer a threshold below which you are exempt.

The digital links requirement matters more than most businesses realise. The data must flow from your records to your return without manual re typing. Exporting a figure from your bookkeeping system and typing it into a spreadsheet, then typing the total into your VAT software, breaks the chain. In practice most businesses meet this simply by using a single accounting package end to end.

Annual accounting and other schemes

The annual accounting scheme, available to businesses with turnover under £1.35 million, replaces four returns with one. You pay by instalments through the year and file a single return within 2 months of the year end rather than the usual 1 month and 7 days.

The flat rate scheme does not change the deadlines at all, only the way the figures are worked out. Cash accounting likewise changes what goes on the return, not when it is due.

Payments on account apply to very large businesses with VAT liabilities above £2.3 million a year. They pay monthly instalments with a balancing payment, and the timing rules differ from the standard system.

What to do if a return is wrong

Small errors can be corrected on your next return. The threshold is the greater of £10,000 net or 1% of your box 6 turnover figure, capped at £50,000. Above that, or where the error was deliberate, a separate disclosure to HMRC is required.

Correcting an error voluntarily before HMRC finds it almost always reduces any penalty, often to nil where the mistake was genuinely careless rather than deliberate. Waiting to see whether it gets noticed is a poor strategy, because the penalty for a prompted disclosure is substantially higher.

Keeping on top of it

The businesses that never have a VAT problem tend to do the same three things. They reconcile the bookkeeping monthly rather than scrambling at quarter end. They keep the VAT money in a separate account, because VAT is never really the business's money in the first place. And they file a week early rather than on the deadline, so a software problem or a bank delay has somewhere to go.

VAT is unusual among taxes in that you are collecting it on HMRC's behalf rather than paying it out of profit. Treating it as belonging to HMRC from the moment it is invoiced removes almost every cash flow problem the deadline can create.

Your first return after registering

The first VAT period after registration is often not a neat three months. HMRC usually sets a longer or shorter opening period to bring you into line with your allocated stagger, so a business registering in February might have a first period running to 30 April, or one running all the way to 30 June.

Check the dates on your registration certificate rather than assuming a quarter. Getting this wrong means either filing for the wrong period or, more commonly, missing the first deadline entirely because you were expecting it three months later than it actually was.

Your first return also often needs to include pre registration input tax. You can reclaim VAT on goods bought in the 4 years before registration that you still hold, and on services bought in the 6 months before registration. That is frequently worth several thousand pounds on stock, equipment and professional fees, and it is claimed on the first return or not at all without a correction later.

Deregistration and the final return

If you deregister, a final return is due covering the period up to the cancellation date, and the deadline is 1 month after that date rather than the usual 1 month and 7 days. It catches people out because it is shorter than every other VAT deadline they have ever met.

The final return also has to account for VAT on any stock and assets you still hold on which you reclaimed VAT, where the total VAT involved is more than £1,000. Businesses closing down often forget this and file a nil final return, which creates a problem later.

What a VAT inspection looks at

Deadlines matter beyond the penalties, because a pattern of late filing is one of the things that draws HMRC attention. A business that files four returns a year on time for several years is unremarkable. A business that files late repeatedly, or files nil returns while clearly trading, moves up the risk profile.

An inspection typically looks at the last 4 years, checks a sample of sales and purchase invoices against the returns, and examines the treatment of anything unusual such as vehicles, entertainment, property or work involving other countries. Clean records and consistent filing make that process short. Missing paperwork and inconsistent filing make it long.
