Research and reports
A business must register for VAT when its taxable turnover exceeds the VAT threshold set by HMRC. But what is the current VAT threshold, and what are the steps you need to take to register?
Before we go into the details of VAT registration for small businesses and the self-employed, let’s start with the basics.
What is VAT? VAT stands for Value Added Tax, which is a type of tax on the consumption of goods and services. Businesses pay VAT when they buy goods and supplies and also charge customers VAT.
If you're not sure how much VAT to charge, we've created a handy calculator you can use to work it out for your business.
In the UK, the VAT threshold for 2023 is £85,000.
The VAT registration threshold is set by HMRC every year. However, it’s been £85,000 since 2017-2018, and the government has confirmed that this threshold won’t change until 31 March 2024.
In the UK, you must register for VAT if your business’s annual taxable turnover goes over this threshold (or you know that it will).
Some businesses will also need to register when selling particular goods or services, and in certain locations or markets, for example Northern Ireland and the EU. Read more about when to register.
Your VAT taxable turnover is the total value of everything you sell that’s not exempt from VAT (exemptions include lottery ticket sales, postage stamps or services, and certain financial services – but VAT is applicable in some form to most goods and services).
If you’re a sole trader and your annual turnover is over the £85,000 threshold, then you’ll need to register your self-employed business for VAT. The VAT threshold applies regardless of your business structure.
You’ll need to provide different information depending on your business structure.

The easiest way is to register online, using your business tax account. Register for VAT online at the UK government’s VAT registration hub.
An agent (for example, an accountant or tax adviser) can also register your business and deal with HMRC for you.
You’ll then receive a VAT certificate from HMRC in the post, within 30 days of registration.
Some businesses can’t register online and will need to download a VAT1 form and send it by post. This can include businesses that are:
You might need to complete an additional form, depending on your business – visit the government’s how to register page for guidance on which one applies.
You must have a VAT certificate in order to charge VAT on sales and show VAT on your invoices.
The certificate will show your:
You’ll get a VAT registration certificate from HMRC as part of the process of registering for VAT. It’s important to make sure you keep information on your VAT certificate up to date, including your address and turnover. Just as you would with your business insurance.
It can take up to 30 days to process VAT registrations and to send your VAT certificate, according to the UK government website.
You’ll get a VAT number as part of the VAT registration process. Once you’ve registered online or by post, you’ll be sent a certificate showing your VAT number. This is the number you’ll include on invoices and can put on your business website.
When buying goods and supplies from other businesses, you might see a VAT number on the invoice. If you want to check if a VAT number is genuine, use the tool on the government website.
As well as on invoices, businesses often show their VAT number on their website.
You can’t charge or show VAT on invoices until you know your VAT number, but you may still need to pay VAT for this period.
The UK government website recommends increasing your prices to allow for this. Explain what’s happening to your customers, and plan to reissue the invoices showing VAT once you have your VAT number.
From your effective date of registration, you’ll need to:

There’s also our Self Assessment and tax hub resource hub, if you need more general information on tax.
Now you’ve registered for VAT, you’ll need to file a VAT tax return.
You’ll usually need to submit a VAT return every three months to HMRC. Our guide to VAT returns has everything you need to know.
VAT registration becomes compulsory when:
Remember, these are calculated on a rolling basis, so it’s not enough to review your taxes once a year and register if your income has exceeded the threshold. You’ll need to keep a regular check on your rolling 30-day and 12-month periods and register on time.
If you think your total VAT taxable turnover will go over £85,000 in the next 30-day period, you’ll need to inform HMRC and register for VAT.
You must do this by the end of that 30-day period, because the effective date of registration is the date you realised (not the date you go over the threshold).
Your business has a typical monthly turnover (all VAT taxable) of £4,000. With some last-minute scaling up, you’ve unexpectedly secured a single contract for £88,000. This will take you over the £85,000 VAT threshold during the next 30 days.
You realised that you’ll exceed the threshold on 1 October 2023, which means you’ll need to register for VAT by 30 October 2023, and your effective date of registration will be 1 October 2023.
If your total VAT taxable turnover for the last 12 months was over £85,000, you’ll need to register. You can check this at the end of every month, but you must register within 30 days of the end of the month you went over the threshold.
Your effective date of registration will be the first day of the second month after you go over the threshold.
Although your typical 12-month turnover is £70,000, you’ve noticed a spike in demand for your product. Looking at the period 31 August 2022 to 30 August 2023, you can see your VAT taxable turnover will go over £90,000, taking you over the £85,000 VAT threshold for that 12 months.
This means you’ll need to register for VAT by 30 September 2023, and your effective date of registration will be 1 October 2023.
You don’t have to exceed the VAT threshold in order to register for VAT – it’s possible to register voluntarily.
But why might you consider doing this? Registering for VAT lets you reclaim VAT on items you buy for your business. If you pay more VAT than you collect from customers, reclaiming VAT makes up the difference.
On the other hand, VAT registration means more paperwork, and sometimes you’ll pay more to HMRC (if you collect more VAT from customers than you pay out). It’s best to look at the specifics of your business when deciding whether to register for VAT.
If you register late, you’ll need to pay the VAT owed from the date you should have registered. You may also get a penalty.
It’s important to stay on top of your accounting so you know if you’re going to go over the threshold. If you do realise that you’ve already exceeded the VAT threshold then it’s important to notify HMRC as soon as possible. You’ll need to work out the date when your taxable turnover went over £85,000.
If you’re taking over a business, check its VAT registration status as early as you can. You may need to register for VAT, even if it’s already registered.
Thresholds don’t apply to businesses outside the UK. You’ll need to register as soon as you supply goods and services to the UK, or if you expect to in the next 30 days.
If you know you’re only going to breach the threshold temporarily, you can apply for an exception.
You’ll need to show evidence why you believe your VAT taxable turnover won’t exceed the deregistration threshold of £83,000 in the next 12 months.
You can write to HMRC using this address:
BT VAT, HM Revenue and Customs, BX9 1WR, United Kingdom
If they agree with your application, HMRC will confirm this with you in writing. If not, they’ll register you for VAT.
Sometimes it might be beneficial for your business to deregister for VAT if your turnover is under the threshold. All you have to do is show HMRC that your taxable turnover will be less than the £83,000 deregistration threshold.
Deregistration isn’t compulsory though, and businesses can continue being VAT registered even if their turnover is less than £85,000.
In some situations, you must cancel your VAT registration by a certain date. For example, you've stopped trading or making VAT taxable supplies.
You can cancel VAT registration online.
You might want to transfer a VAT registration from one business to another, or if the status of your business changes (for example from partnership to sole trader).
