How the Flat Rate Scheme works

On the VAT Flat Rate Scheme you still charge your customers the normal 20% VAT, but you pay HMRC a fixed percentage of your VAT-inclusive (gross) turnover instead of accounting for VAT on every sale and purchase. The percentage depends on your trade sector.

Worked example. An IT consultant invoices £10,000 + £2,000 VAT = £12,000 gross. At a 14.5% flat rate they pay HMRC 14.5% × £12,000 = £1,740, keeping the £260 difference. (A 1% discount applies in your first year of registration.)

Flat rate percentages by sector

Retail (food, confectionery, tobacco, newspapers)4%

Watch the 16.5% limited cost trader rate: if your goods cost less than 2% of turnover (or under £1,000 a year) you must use it, which usually wipes out the benefit of the scheme.

Who can join

You can apply if your VAT taxable turnover is £150,000 or less (excluding VAT). You must leave once your total income exceeds £230,000. Use the calculator above to add 20% VAT to your invoices, then apply your flat rate percentage to the gross total.
