Understanding VAT Returns: Essential Guidance for UK Businesses

If your business is VAT registered, submitting VAT returns is a routine but important part of staying compliant. The process can feel complicated at first, but once you understand the structure and what HMRC expects, it becomes much easier to manage. VAT returns also give you a chance to understand your cash flow better and ensure you reclaim everything you are entitled to.

This guide explains how VAT returns work, why they matter and how to stay organised so you avoid penalties and unnecessary stress.

What a VAT return actually is

A VAT return is a report that tells HMRC how much VAT you charged customers, how much VAT you paid on your own purchases and whether you owe money to HMRC or are due a refund. Most businesses file quarterly, although HMRC may place you on a different cycle depending on your scheme.

A return usually includes total sales, total purchases, VAT collected, VAT reclaimable and any adjustments. Even if you made no sales in a period, you still must submit the return.

Good record-keeping makes this process far easier. When your figures are correct and supported by documentation, you reduce the risk of mistakes or overpaying VAT. Using reliable software helps keep all transactions in order and reduces manual work.

Who needs to submit VAT returns

If your taxable turnover exceeds the VAT threshold, you must register and start submitting returns. As of April 2024, the threshold is £90,000. If you expect to exceed it soon, you must plan ahead because late registration can lead to penalties.

Some businesses choose to register voluntarily. This is common for those who regularly work with VAT-registered suppliers or want to reclaim VAT on purchases. Voluntary registration also makes your business appear more established when dealing with larger organisations.

Whatever route applies to you, the key is consistent monitoring. Regular reviews of your turnover prevent surprises and keep you compliant.

How often VAT returns are filed

Most businesses submit quarterly returns. Some prefer monthly submissions, especially those that reclaim VAT frequently. Monthly refunds can improve cash flow, but the admin workload increases. The Annual Accounting Scheme is another option. It allows you to file a single yearly return and make payments on account.

Choosing the right option depends on your turnover patterns, cash flow needs and how much admin capacity you have. If you are unsure, an accountant can help you work through the pros and cons.

What information you need to complete a VAT return

Before you start, gather the records for your sales and purchases, copies of VAT invoices, details of imports and exports, and any adjustments for things such as bad debt relief or partial exemption. You also need digital records if you fall under Making Tax Digital rules, which now apply to most VAT-registered businesses.

Accurate data ensures your return is complete and correct. Errors often happen when invoices are missing or when adjustments are not recorded properly.

Submitting a VAT return

Since 2022, VAT returns must be filed using Making Tax Digital-compatible software. You cannot type figures manually into the HMRC portal. Software such as Xero, QuickBooks, Sage or FreeAgent can file returns directly. If you prefer spreadsheets, you must use bridging software.

Filing through software reduces errors and creates a clear audit trail. It also helps you prepare earlier because the figures update automatically.

What happens if you miss the deadline

Missing a VAT deadline can lead to interest charges, penalties and a weakened compliance history with HMRC. Late submissions may trigger reviews or audits, which take time away from running your business.

VAT deadlines are usually one month and seven days after the end of your VAT period. For example, if your quarter ends on 30 June, the deadline is 7 August. Setting reminders and using software alerts can prevent late submissions.

Practical ways to stay organised

Start by using cloud-based accounting software that updates your VAT figures automatically. Set calendar reminders for each VAT deadline and review your records monthly rather than saving everything until the end of the quarter.

For many businesses, working with an accountant creates extra confidence. They help ensure your returns are correct, advise on VAT schemes and provide support if your business becomes more complex. This is especially helpful for international trade or partial exemption.

Good organisation turns VAT returns from a rushed quarterly task into a simple routine. Strong systems also help with cash flow planning and keep your compliance intact.
