What is the VAT registration threshold?
The VAT registration threshold is the level of taxable turnover at which a business must register for VAT with HMRC. In the UK, the current mandatory registration threshold is £90,000 in taxable turnover over a rolling 12-month period.
This means you do not just look at your last set of accounts. Instead, you must monitor your turnover continuously and check whether you have crossed the limit at any point in the previous 12 months.
What counts towards the threshold?
The threshold is based on taxable turnover, not total profit. Taxable turnover usually includes most goods and services that are subject to VAT, even if you have not yet charged VAT on them.
It does not include exempt supplies, such as certain financial services or insurance. If your business sells a mix of taxable and exempt items, only the taxable part is counted when checking the threshold.
When must you register?
If your taxable turnover goes over £90,000 in any rolling 12-month period, you must register for VAT. You then need to notify HMRC within 30 days of the end of the month in which you went over the threshold.
Your VAT registration usually starts from the date you exceeded the threshold, not from the date you inform HMRC. This means you may need to charge VAT on sales made after that date, even before your registration is confirmed.
Can you register voluntarily?
Yes, businesses can choose to register for VAT even if they are below the threshold. Voluntary registration can be useful if you buy a lot of VATable goods or services, because you may be able to reclaim input VAT.
It may also help if your customers are mainly VAT-registered businesses, since they can usually reclaim the VAT you charge. However, voluntary registration also means extra admin and the need to submit VAT returns.
What happens if you go over the threshold?
If you fail to register on time, HMRC can charge penalties and interest. You may also have to pay the VAT that should have been charged from the date you became liable to register.
For this reason, it is important to track turnover carefully, especially if your business is growing quickly. Many businesses review their figures monthly to make sure they do not miss the point at which registration becomes mandatory.
Why the threshold matters
The VAT threshold is an important compliance issue for small and medium-sized businesses in the UK. It affects pricing, cash flow, and how you invoice customers.
Knowing the threshold early helps you plan ahead and avoid surprise tax bills. If you think you may be close to £90,000, it is wise to speak to an accountant or check HMRC guidance.
