When do you need to register for VAT and how do you do it?

If you are running a business, regardless of whether you operate as a sole trader, in partnership or the business is run as a limited company, you will need to register for VAT if your total taxable turnover in the previous 12 months exceeds the VAT registration threshold. As of April 2024, this threshold stands at £90,000. Understanding when and how to register is crucial to staying compliant with HMRC regulations and avoiding penalties. In this guide, we’ll walk you through the key rules and the registration process itself.

Understanding the VAT Registration Threshold

The VAT threshold is the point at which you become legally required to register. For the current tax year, if your taxable turnover reaches £90,000 or more over a rolling 12-month period, you must register. It’s important to note that this threshold applies to taxable turnover — essentially, the sales on which VAT is normally charged. Certain supplies, such as financial services or the sale of land, are often exempt from VAT and therefore don’t count towards your threshold.

You don’t have to wait until you’ve hit the threshold to register, however. You can voluntarily register for VAT at any point if you believe it’s beneficial to your business. This might be the case if you deal with other VAT-registered businesses who can reclaim VAT on their purchases from you, or if you’re planning to import goods from outside the UK.

When You Must Register

You become liable to register when your taxable turnover exceeds £90,000. Importantly, HMRC expects you to register within 30 days of the end of the month in which you cross this threshold. Failure to register on time can result in penalties and back-dated VAT liability, so it’s essential to monitor your turnover carefully, particularly during periods of growth.

There are specific circumstances that can trigger immediate registration requirements. For example, if you take over a going concern as a business, you must register straight away if the previous owner was VAT-registered. Similarly, if you’re a limited company purchasing a business from a sole trader, VAT registration may be automatic depending on the structure of the deal.

How to Register for VAT

The process is straightforward and can be completed entirely online through HMRC’s online services portal. You’ll need your Unique Taxpayer Reference (UTR), Company House registration number (if you’re a limited company) and details about your business, including your business address, the nature of your activities and an estimated turnover figure.

You can register using the Government Gateway, HMRC’s secure online portal. The process typically takes just a few minutes to complete. Once submitted, you’ll usually receive your VAT registration number within a few days. HMRC will issue you with a Certificate of Registration, which you should keep safely — you’ll need your VAT number for all future tax correspondence and business transactions.

It’s worth noting that your VAT registration date won’t necessarily be the same as the date you apply. HMRC often backdate registrations to the date your turnover exceeded the threshold, which means you could be liable for VAT on sales from several weeks or months before you actually registered. This is another reason to act quickly when you realise you’ve crossed the threshold.

Key Considerations Before You Register

Once registered for VAT, you’re required to charge VAT on your taxable supplies and file VAT returns regularly — typically every three months. You’ll also need to keep detailed records of all sales and purchases. For many small business owners, this administrative burden is worth considering carefully. Voluntary registration, for instance, only makes sense if the benefit of recovering input VAT outweighs the compliance costs.

If your turnover falls below £90,000, you can apply for exemption from VAT registration. However, you’ll need to demonstrate that your turnover is unlikely to exceed the threshold in the next 12 months. HMRC takes these applications seriously and will want evidence to support your claim.

The Bottom Line

VAT registration is a significant milestone for any growing business. Understanding the threshold, monitoring your turnover and registering promptly ensures you remain compliant with HMRC requirements and avoid costly penalties. Whether you need to register or are considering voluntary registration, getting the decision right from the start is essential.
