What Is the VAT Threshold?
The VAT threshold is the amount of VAT-taxable turnover you can make in any rolling 12-month period before HMRC requires you to register for Value Added Tax.
Put simply, if the total value of goods or services you sell that are subject to VAT goes over this limit, you must register with HMRC and start adding VAT to your prices.
For the 2025 tax year, the VAT registration threshold in the UK is £90,000. This isn’t measured by calendar year or tax year it’s a rolling total. That means you look back over the last 12 months at any point in the year, and if your taxable turnover has reached or gone over £90,000, you’ll need to register.
How the Rolling 12-Month VAT Threshold Works
A lot of people think that HMRC checks the VAT threshold once a year, like they do with your tax return. But that’s not true. You can always look back at your most recent year of sales, not just at the end of the tax year, because the VAT threshold is measured on a rolling 12-month basis.
Here’s how it works in 2025:
- You add up your VAT-taxable sales for the last 12 months at the end of each month.
- You have to register for VAT if that total is £90,000 or more.
For example, imagine your business makes:
- £7,000 every month from January to June 2024
- Then it goes up to £8,500 a month from July 2024 to June 2025.
- By June 2025, your total for the last 12 months would be £93,000, which means you went over the VAT limit even though you never made £90,000 in a single year.
Or think about a seasonal business maybe you usually earn around £5,200 per month, but in November and December your sales shoot up to £16,000 a month thanks to Christmas demand. That holiday boom could easily push your rolling 12-month total past £90,000, even if most of the year you were well below it.
What Happens When You Cross the VAT Threshold?
You usually have 30 days to register for VAT with HMRC after your turnover goes over the VAT threshold. You will have to start adding VAT to your sales and sending in regular VAT returns, usually every three months, starting on the day you register. If you miss the deadline, HMRC can fine you, add interest, and even make you pay VAT that you didn’t collect from your customers. So it’s always best to act quickly.
What Counts Towards the VAT Threshold?
The VAT threshold is based on your VAT-taxable turnover, not your total income. This means you add up all sales that would have VAT applied if you were registered whether they’re standard-rated at 20%, reduced-rated at 5%, or zero-rated at 0%. For example, if you sell £60,000 worth of standard-rated goods, £20,000 of reduced-rated items, and £10,000 of zero-rated products in a 12-month period, your taxable turnover would be £90,000, hitting the threshold. It doesn’t include VAT-exempt sales, such as most financial services, insurance, or certain types of education.
Voluntary Registration Below the Threshold
You don’t need to wait until your turnover reaches the £90,000 VAT threshold to register. Many small businesses choose to do it early mainly to claim VAT back on purchases, look more professional to clients, and avoid sudden changes when they pass the limit.
| Type of Business | Annual Turnover | Typical Annual Costs (excl. VAT) | Why Early Registration Helps |
| Freelance graphic designer | £35,000 | £8,000 equipment & software | Can get back VAT on big costs up front |
| Retail shop | £60,000 | £25,000 stock purchases | Large savings on VAT for stock |
| Consultancy firm | £50,000 | £5,000 travel & office expenses | A professional look for business clients |
Of course, registering means more work for the government, like filing quarterly VAT returns, keeping records, and changing prices to include VAT. So it’s a good idea to think about the pros and cons before making a decision.
The Current VAT Threshold and Past Changes
For years VAT threshold stayed at £85,000, until April 2024 when it went up to £90,000 around a 6% rise. In 2025, it’s still £90,000, but that could change in the future depending on things like inflation, government budgets, or even international agreements such as the Northern Ireland Protocol. It’s a good idea to check the number each tax year so you don’t get caught out.
Common Mistakes Businesses Make
Some business owners only check their turnover once a year, and by then they may have been over the VAT threshold for months, owing backdated VAT to HMRC. Others track the wrong figures, focusing on profit instead of VAT-taxable turnover, which includes UK sales even if they’re made online from abroad. Seasonal peaks can also catch people out a busy Christmas period, a sudden growth spurt, or one big order can easily push turnover past the limit without them realising.
Strategies to Stay on Top of the VAT Threshold
Staying on top of the VAT threshold isn’t just about avoiding penalties it’s about being prepared so your business runs smoothly. A little forward planning can save you a lot of stress later. Here are some simple ways to keep yourself in control.
Track your turnover every month
Don’t leave it until the end of the year. Check your sales monthly so you can see exactly where you stand. If you’re getting close to the threshold, you’ll have time to prepare.
Use smart accounting tools
Modern accounting software can do more than just keep records it can give you alerts when your turnover is approaching the VAT threshold. This makes it easier to act before you go over the limit.
Plan ahead for higher sales
If business is picking up and you’re going to pass the threshold soon, get ready ahead of time. Change your prices, change your invoices, and make sure your systems can handle VAT without any problems.

How to Deregister from VAT
You can usually ask to not have to pay VAT if you make less than £88,000 a year. You won’t have to file VAT returns anymore, which will make your job easier. But it’s not always the best thing to do, especially if you get VAT back on business purchases often. You would lose that benefit. Deregistering can also mean lowering your prices to get rid of VAT. This could confuse customers who are used to your old prices. It’s a good idea to think about the pros and cons of something before you choose it.
VAT Threshold for Overseas Businesses
The rules are stricter if your business is not based in the UK. You have to register for VAT as soon as you make your first sale to a UK customer; there is no £90,000 limit. This is very important for online sellers who ship from other countries, because even if you only sell £1,000 worth of goods in the UK, you may still need to register.
Why the VAT Threshold Affects More Than Taxes
When you go over the VAT threshold, you don’t just have to pay VAT. It can also change how your business works. You’ll need to keep better records and stay on top of your paperwork.
- You may have to change your prices to include VAT.
- People can change how they feel about your business. Some people may not like the higher prices, but others may think you are more professional and established.
In short, going over the VAT limit is a financial and strategic choice, so it’s best to plan ahead.

FAQs
Are sales to other countries included in the VAT threshold?
If you sell to people outside the UK, those sales usually don’t count towards the VAT threshold. Sales to people in Northern Ireland or sales that fall under certain UK VAT rules are the only exceptions. Before you leave out a sale, make sure you know what kind it is.
What will happen if I accidentally go over the VAT limit?
You still need to sign up as soon as you know you’ve gone over the limit. If HMRC changes the date of your registration, you may have to pay VAT on sales you made in the past. That’s why you should check your turnover every month.
Is it possible for two small businesses to share a VAT threshold?
No, the VAT limit is different for each company. But if HMRC thinks that two businesses are really one business that has been split up to avoid VAT, they can add up the sales and make you sign up.
Is the VAT limit the same for all fields?
Yes. Most businesses in the UK, no matter what they sell or do, have to pay VAT on sales over £90,000. The only difference is that businesses outside the UK that sell to the UK don’t have a limit and have to register from the first sale.
If I unregister from VAT, can I register again later?
If your sales go up again or if you just want to register again, you can do so. Just remember that you have to follow all of the VAT rules from the day you sign up.
