eu_vat_rates_data · Ruby

VAT rates for 44 European countries — EU-27 plus Norway, Switzerland, UK, and more. EU rates sourced from the European Commission TEDB and checked daily. Non-EU rates maintained manually.

• Standard, reduced, super-reduced, and parking rates
• eu_member flag on every country — true for EU-27, false for non-EU
• vat_name — official name of the VAT tax in the country's primary official language
• vat_abbr — short abbreviation used locally (e.g. "ALV", "MwSt", "TVA")
• format — human-readable VAT number format (e.g. "ATU + 8 digits") — unique to this package
• pattern — regex for VAT number validation + built-in valid_format?() — free, no API key needed — unique to this package
• No dependencies — pure Ruby 3.0+
• Data bundled in the gem — works offline, no network calls
• EU rates checked daily via GitHub Actions, new version published only when rates change

Also available in: JavaScript/TypeScript (npm) · Python (PyPI) · PHP (Packagist) · Go

• EU-27 rates: European Commission TEDB, refreshed daily at 07:00 UTC
• Non-EU rates: maintained manually, updated on official rate changes
• Published to RubyGems only when actual rates change

Rates are bundled at install time. A new package version is published automatically whenever rates change — but your installed version will not update itself.

Recommended: add Renovate or Dependabot to your repo. They detect new versions and open a PR automatically whenever rates change — no manual update commands needed.

No package needed — parse it with a single fetch() / http.get() / file_get_contents() call and cache locally.

This package provides VAT rates only. If you also need to validate EU VAT numbers against the official VIES database — confirming a business is VAT-registered — check out vatnode.dev, a simple REST API with a free tier.
