VAT Rates is a European VAT rates API: send a two-letter country code and get the current VAT rates for that country as JSON, with the full standard, reduced, super-reduced and parking set for EU members plus the UK, and standard rates for non-EU countries such as Switzerland and Norway. Paid plans add historical rates by date and regional exceptions by postcode.
