When must you register for VAT?
You must register for VAT if your VAT-taxable turnover goes over £90,000 in any rolling 12-month period, not just your accounting year. You also have to register if you expect to go over the threshold within the next 30 days alone. The £90,000 threshold has applied since 1 April 2024.
Turnover here means your total taxable sales, before expenses. Enter your rolling 12-month turnover and this tool tells you whether you have crossed the line and, if not, how much room is left.
Voluntary registration and deregistration
You can register voluntarily below the threshold, which lets you reclaim VAT on purchases and can look more established to clients, though it means charging VAT to customers. Many B2B businesses register early for this reason.
You can apply to deregister if your taxable turnover falls below £88,000. Watch the rolling total carefully as you approach £90,000, because registration is a legal requirement once you cross it.
Worked example
A business with £70,000 of rolling 12-month turnover is £20,000 below the £90,000 threshold and does not have to register yet.
If turnover reaches £95,000, the business is £5,000 over and must register for VAT.
Please note: General guidance based on the £90,000 threshold, not tax advice. Check GOV.UK or an accountant for your situation.
Frequently asked questions
Is the threshold on the tax year?
No. It is a rolling 12-month figure, so you check the total for any recent 12-month period, not just your accounting year.
What counts as taxable turnover?
Your total sales that are not exempt from VAT, before deducting expenses. Most standard, reduced and zero-rated sales count.
Can I register voluntarily?
Yes. Below the threshold you can still register, which lets you reclaim VAT on purchases but means charging VAT to your customers.
What is the current threshold?
The registration threshold is £90,000 and the deregistration threshold is £88,000, both from 1 April 2024.
