Frequently asked questions

Divide the gross price by (1 + rate). For 20% VAT: gross ÷ 1.20 gives the net; the difference is the VAT. Note: you do NOT subtract 20% of the gross — that over-removes.

The UK standard rate is 20% with a 5% reduced rate. EU standard rates range roughly from 17% to 27% by country. Use the custom field for any other rate.
