VAT Return Deadlines and Payment Explained for UK Firms

Once your business is VAT registered, the calendar starts to matter. You have to file VAT returns on time and pay what you owe by the due date. Miss either and HMRC can add penalties and interest. This guide explains how VAT return periods work, when the filing and payment deadlines fall, the main payment methods and the habits that keep a business out of trouble.

Key takeaways

• Most VAT-registered businesses file returns every quarter, using Making Tax Digital compatible software.
• The return and payment are usually due one month and seven days after the end of the period.
• You must file a return even if you owe nothing.
• Direct Debit and bank transfers work differently, so allow for clearing time.
• Late returns and payments lead to penalties and interest. Check the current rules on GOV.UK.

What is a VAT return?

A VAT return is the summary you send to HMRC for each VAT accounting period. It reports the VAT you charged on sales, the VAT you can reclaim on purchases and the difference between the two. If you charged more than you can reclaim, you pay the balance. If you can reclaim more, HMRC repays you. Most businesses have to send returns digitally through software that works with Making Tax Digital for VAT. You can read the current rules on GOV.UK's VAT Returns guidance.

How VAT periods work

Your VAT accounting periods are set by HMRC when you register. Most businesses have quarterly periods, which means four returns a year. The periods do not always follow the calendar year or the tax year, so your quarter ends could be the end of January, April, July and October, or any other pattern assigned to you. Your VAT online account shows the exact dates for each return.

Some businesses can use different schemes that change the timing, such as annual accounting, where you file one return a year and make payments on account. The Flat Rate Scheme also affects how the amount is calculated but not the basic return cycle. Our guide to the Flat Rate Scheme versus standard VAT explains the difference.

Filing and payment deadlines

For most businesses on standard quarterly returns, the deadline for both the return and electronic payment is one month and seven days after the end of the accounting period. The extra seven days are built in to the normal deadline.

These dates are examples for a common pattern, and HMRC may issue different dates for your own periods. Always rely on the dates in your HMRC account. Your deadline may also move if it falls at a weekend, depending on the payment method you use, so check the payment guidance rather than assuming.

How to pay

You can pay HMRC in several ways, and the best one depends on how much notice you have and how you like to manage cash. The main options are Direct Debit, online or telephone banking by Faster Payment, debit or corporate credit card and bank transfer. Direct Debit is popular because the money is collected for you, but you need to set it up well in advance and your return still needs to be filed by the deadline. HMRC collects the Direct Debit a few working days after the due date, so the payment is on time provided the mandate is in place.

Other methods can take a day or more to clear, so paying on the last day risks a late payment. Check GOV.UK's guidance on paying VAT for current methods and timings. Make sure that the bank account you intend to use has enough cash on the day.

Building a simple VAT routine

Businesses that file late usually have the same underlying problem: records are not up to date when the quarter ends. A simple routine fixes most of that:

• Record sales and purchase invoices as they arise, not at quarter end.
• Reconcile your bank account monthly so missing items show up early.
• Put a calendar reminder two weeks before each filing deadline.
• Move the VAT you collect into a separate savings pot so it is not spent.
• Review the draft return before submitting it, looking for unusual figures.

Good bookkeeping makes all of this easier. Our guide to bookkeeping service versus DIY can help you decide who should keep the records.

Worked example (illustrative)

"Northside Cleaning Ltd", an illustrative company, has a VAT quarter ending on 30 June. The return and payment would normally be due by 7 August. During the quarter it charged £6,000 of VAT on its sales and reclaimed £1,800 of VAT on supplies and equipment, so the balance due is £4,200. The business owner files the return on 2 August and has a Direct Debit in place, so HMRC collects the £4,200 a few working days after the due date. Because the money was set aside during the quarter, the payment does not hurt cash flow. The numbers are invented for illustration.

What happens if you are late

HMRC uses a points-based penalty system for late VAT returns. Each missed deadline can add a point, and once you reach the threshold, a financial penalty applies, with further penalties for each later miss. Late payment has its own penalty regime, based on how long the amount stays unpaid, and interest can also be charged. The thresholds and amounts are set by HMRC and can change, so read the current rules on GOV.UK. The practical message is that regular on-time filing keeps points off your record, and a short delay is far cheaper than a long one.

Payment on account and annual schemes

Not every VAT-registered business follows the standard quarterly pattern. Under the Annual Accounting Scheme, you file one return a year and make advance payments during the year based on an estimate, then settle the balance with the return. That reduces the number of returns, but the payments still need to be made on time and the scheme has eligibility rules. Very large businesses can also be required to make payments on account under different rules. If you are on a scheme, your VAT online account and the letter from HMRC will show the right dates, and you should follow those rather than the standard pattern.

Making Tax Digital and VAT

VAT-registered businesses must keep digital records and submit returns using compatible software. In practice that means your return is built from the figures in your software and sent directly to HMRC, rather than typed into a web page. If your records are on a spreadsheet, you need bridging software to send the figures. Our guide to MTD bridging software explains how that works. Make sure your software is authorised with HMRC well before your first deadline, because linking it can take a little time.

Another practical point is to keep your VAT invoices in order. You can only reclaim VAT if you hold a valid VAT invoice, and HMRC can ask for them if they review your return. A simple folder structure by quarter, or a scanning app connected to your software, makes the process far easier.

Correcting a mistake after you file

Everyone makes errors occasionally. If you find a mistake in a return you have already sent, you may be able to correct it on your next return if the net error is below a limit set by HMRC. Larger errors usually need to be reported separately to HMRC. The limits and the process are on GOV.UK, so check them before you decide how to handle the correction. In both cases, keep a note of what went wrong, how you found it and what you changed, because HMRC may ask.

If you realise before the deadline that you cannot pay in full, contact HMRC early. Talking to them before the date usually leads to a better outcome than staying silent and hoping.

Common mistakes

• Forgetting nil returns. You still need to file when no VAT is due.
• Spending the VAT. The VAT you collect is not your income. Keep it aside.
• Paying on the deadline by slow methods. Allow time for the payment to clear.
• Using the wrong period dates. Check your HMRC account, not the calendar quarter.
• Reclaiming VAT without a valid invoice. Keep VAT invoices for everything you reclaim.
