How Does the £90,000 Rolling VAT Registration Threshold Work?

In the UK, you must register for VAT if your VAT-taxable turnover exceeds £90,000 on a rolling 12-month basis, or if you expect your turnover to exceed £90,000 in the next 30 days alone (the 30-day forward-look test). It is not measured by the calendar year or tax year.

Rolling 12-Month Rule: At the end of every calendar month, add up your total taxable turnover for the previous 12 months. If the rolling sum exceeds £90,000, you have 30 days to register with HMRC.

How Do You Calculate VAT Backwards (The 1/6th Fraction Trick)?

To extract 20% VAT from a gross (VAT-inclusive) total, you cannot simply subtract 20%, as this produces an incorrect figure. Instead, multiply the gross price by 1/6 (or divide by 1.20).

Frequently Asked Questions

What is the UK VAT registration threshold for 2026/27?

The statutory UK VAT registration threshold is £90,000 based on a rolling 12-month taxable turnover or a 30-day forward-look test, not a fixed calendar or tax year.

How do you calculate 20% VAT backwards?

To extract 20% VAT from a gross amount, multiply the gross price by the 1/6th VAT fraction (or divide gross by 1.20). Subtracting 20% directly produces an incorrect figure.

What are the UK VAT rates for 2026/27?

What is the VAT Flat Rate Scheme?

The Flat Rate Scheme allows small businesses with turnover up to £150,000 to pay a fixed statutory percentage (4% to 16.5% depending on industry sector) of gross turnover directly to HMRC.

Which goods and services are zero-rated for VAT?

Zero-rated items (0% VAT) include basic food and drink, books, newspapers, children's clothing, public transport, and new-build residential property, allowing businesses to still reclaim input VAT.
