Methodology
EU VAT Kit is built as a calculation helper for common VAT arithmetic and invoice preparation checks. It is not tax, legal, accounting, or financial advice.
Rate data
Standard and reduced VAT rate references are checked against European Commission, Your Europe, and national tax authority sources where appropriate.
Each country page shows the standard rate used by the calculator and a short reference for reduced, super-reduced, and parking rates where available.
Calculation formulas
- Add VAT: gross = net x (1 + VAT rate).
- Remove VAT: net = gross / (1 + VAT rate).
- VAT from gross: VAT = gross - gross / (1 + VAT rate).
- VAT from net: VAT = net x VAT rate.
What the tools do not decide
The calculator does not decide whether a reduced rate, exemption, domestic reverse charge, marketplace rule, import rule, or OSS/IOSS rule applies. Those questions depend on the product, service, customer type, country, and transaction facts.
Machine-readable data
The VAT rate dataset used by the site is available as JSON at /vat-rates.json. The JSON includes the update date, country list, rates, currency labels, EU scope flag, and source links.
