If your business reaches the VAT threshold, you must register for VAT with HMRC.
VAT registration is an important step that affects how you price your products or services, manage your finances, and report your taxes.
VAT registration in the UK is required when your business turnover exceeds the VAT threshold set by HMRC.
This guide explains when you need to register, how to do it, and what happens after registration.
When Do You Need to Register for VAT?
You must register for VAT if your taxable turnover exceeds the UK VAT threshold.
As of 2026, the threshold is £90,000 in a rolling 12-month period.
You must also register if you expect your turnover to exceed this amount within the next 30 days.
You must register for VAT if your taxable turnover goes over the current threshold, or if you expect it to in the next 30 days.
Can You Register for VAT Voluntarily?
Yes, businesses can register for VAT voluntarily even if they are below the threshold.
This may be beneficial if:
- You want to reclaim VAT on expenses
- You work with VAT-registered clients
- You want to appear more established
However, you will need to charge VAT on your sales.
