How this calculator works
UK VAT has three rates: 20% (standard — most goods and services), 5% (reduced — domestic fuel, children's car seats, etc.), and 0% (zero-rated — most food, books, children's clothes). Some things are exempt — different from zero, and you can't reclaim VAT on costs related to them.
You usually must register for VAT once taxable turnover exceeds the £90,000 registration threshold in a rolling 12-month period, or where you expect to exceed it in the next 30 days. Registration can also be voluntary below the threshold; check GOV.UK guidance for exceptions and current thresholds.
The Flat Rate Scheme lets businesses with turnover under £150k pay a fixed % of their gross turnover instead of tracking VAT on every purchase. The default rate for "limited cost traders" (those spending less than 2% of turnover on goods) is 16.5%, which effectively removes most of the benefit.
