Description
Add or remove UK VAT instantly (20%, 5%, 0% or custom). Shows net, VAT and gross, plus the 1/6 shortcut. No sign-up, works offline. A fast, private UK VAT calculator that lives in your toolbar. Add VAT to a net figure or strip the VAT out of a gross one, at the standard 20% rate, the reduced 5% and zero rates, or any custom rate you type. It shows the net, the VAT amount and the gross side by side, and reminds you of the 1/6 shortcut (at 20%, the VAT inside a price is one-sixth of the gross - so dividing by 1.2 is right, subtracting 20% is the common and costly slip). Built for freelancers, bookkeepers, and small business owners who check VAT on invoices all day. Everything runs locally in your browser - the extension asks for no permissions, makes no network calls, and collects no data. The full source is public. For the Flat Rate Scheme, the limited cost trader trap, and the GBP 90,000 registration threshold, the full calculator and guide are one click away at UK Finance Tools.
