A few useful answers.
Which UK VAT rates are included?
The standard rate is 20%, the reduced rate is 5% and the zero rate is 0%, as checked on 6 October 2026. Eligibility depends on the goods or services. Exemption is different from zero rating.
Check the current GOV.UK VAT ratesHow do I remove VAT from a total?
Choose Gross, including VAT. The calculator estimates the VAT included in that amount, then subtracts it to show net. At 20%, the VAT portion is one sixth of the gross amount.
Can this tell me what VAT I can reclaim?
No. This is an arithmetic estimate. The receipt, your circumstances and the applicable rules matter. Check with your accountant.
