Using 2026/27 figures

0% is not shown — there is no VAT to remove.

Don’t subtract 20% directly. £1,200 × 0.80 = £960.00 (wrong). Correct: £1,200 ÷ 1.20 = £1,000.

Under HMRC’s Flat Rate Scheme (FRS), you charge customers the standard VAT rate but pay HMRC a fixed percentage of your gross turnover instead. This can simplify your accounting and sometimes saves money.

VAT registration thresholds

You must register for VAT when your taxable turnover exceeds £90,000 in any rolling 12-month period (2026/27).

The deregistration threshold is £88,000.

You can register voluntarily below the threshold.

Common questions

How do I add VAT to a price?

Multiply the net price by 1.20 for the standard 20% rate. Example: £500 × 1.20 = £600 (£100 VAT). For the 5% rate, multiply by 1.05.

How do I remove VAT from a price?

Divide the gross price by 1.20 for standard rate. Example: £1,200 ÷ 1.20 = £1,000 (VAT was £200). Do not subtract 20% directly — that gives the wrong answer.

What is the VAT registration threshold in 2026/27?

£90,000 rolling 12-month turnover. The deregistration threshold is £88,000. These figures are pulled automatically from our config and updated each tax year.

What is the Flat Rate Scheme?

HMRC’s Flat Rate Scheme lets eligible businesses pay a single fixed percentage of gross turnover as VAT, instead of accounting for VAT on each transaction. Rates vary by industry (7%–16.5%).

What is a limited cost trader?

A business on the Flat Rate Scheme whose goods cost less than 2% of their turnover or less than £1,000 per year. Limited cost traders must use the 16.5% flat rate.
