This calculator handles the standard UK VAT bands. It does not handle the domestic reverse-charge for construction services, partial exemption, or VAT margin schemes — those need accountant input.
Most VAT mistakes in UK service businesses come from one of three places: pulling VAT out of a gross figure with the wrong formula, applying the wrong rate to reduced-rate work, or forgetting that some materials and some services are zero-rated. None of those are complicated once you know the maths — they're just easy to do quickly and get wrong.
If you're VAT registered, this calculator covers the common cases: adding VAT for a quote, removing VAT from a gross figure when reconciling a receipt, and switching between 20%, 5% and 0% rates. Anything more complex (reverse-charge, partial exemption, margin schemes) needs your accountant.
