Question 1

What is the compulsory UK VAT registration threshold in 2026?

Accepted Answer

The compulsory UK VAT registration threshold is **£90,000**. You MUST register for VAT with HMRC if your total VAT-taxable turnover for the past 12 consecutive months exceeds £90,000, OR if you expect your turnover to exceed £90,000 in the next 30 days alone.

Question 2

How is the rolling 12-month VAT turnover calculated?

Accepted Answer

VAT turnover is calculated on a **rolling 12-month basis**, NOT on your fixed accounting financial year. At the end of every calendar month, you must add up your total taxable sales over the past 12 months.

Question 3

What is the HMRC VAT Flat Rate Scheme (FRS)?

Accepted Answer

The Flat Rate Scheme simplifies VAT for small businesses with turnover under £150,000. Instead of calculating VAT on every purchase, you charge customers standard 20% VAT and pay HMRC a fixed lower percentage of your gross turnover (e.g. 14.5% for IT consultancy, 12% for catering).

Question 4

What happens if I register for VAT late after crossing £90,000?

Accepted Answer

If you fail to register within 30 days of crossing £90,000, HMRC imposes late registration penalties ranging from 5% to 15% of the net VAT owed from the date you should have registered.

Question 5

Can non-UK established businesses register for UK VAT?

Accepted Answer

Non-established foreign businesses selling goods or digital services to UK customers have a **£0 VAT threshold**! They must register for UK VAT from their very first sale.
