eu-vat-rates-data-go

VAT rates for 45 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
• EUMember field on every country — true for EU-27, false for non-EU
• VATName — official name of the VAT tax in the country's primary official language
• VATAbbr — 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 ValidateFormat() — free, no API key needed — unique to this package
• Zero dependencies — data embedded with //go:embed
• Fully typed — works with Go 1.21+
• EU rates checked daily via GitHub Actions, new version tagged only when rates change

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

Need live VIES validation?

This package gives you VAT rates and format checks for free, offline, in your code. It does not call VIES — ValidateFormat() only checks the shape of a VAT number, not whether it actually exists.

For live VIES validation — confirming a VAT ID is real, pulling the registered company name and address, and getting a VIES consultation number (audit-grade proof of validation) — there's vatnode:

• Live VIES validation, with national-database fallback when VIES is down
• Registered company name, address, registration date
• VIES consultation number for compliance and audit trails
• Webhooks for VAT status changes
• Official MCP server so AI agents (Claude, Cursor, ChatGPT) can validate VAT IDs directly
• Free tier — no credit card needed

Usage

package main

import (
    "fmt"
    euvatrates "github.com/vatnode/eu-vat-rates-data-go"
)

func main() {
    // Full rate struct for a country
    fi, ok := euvatrates.GetRate("FI")
    if ok {
        fmt.Printf("%s: %.1f%% (EU member: %v, tax: %s / %s)\n", fi.Country, fi.Standard, fi.EUMember, fi.VATName, fi.VATAbbr)
        // Finland: 25.5% (EU member: true, tax: Arvonlisävero / ALV)
    }

    // Just the standard rate
    standard, ok := euvatrates.GetStandardRate("DE")
    fmt.Println(standard) // 19

    // EU membership check — false for non-EU countries (GB, NO, CH, ...)
    if euvatrates.IsEUMember(userInput) {
        rate, _ := euvatrates.GetRate(userInput)
        _ = rate
    }

    // Dataset membership check (all 45 countries)
    if euvatrates.HasRate(userInput) {
        rate, _ := euvatrates.GetRate(userInput)
        _ = rate
    }

    // All 45 countries
    all := euvatrates.GetAllRates()
    for code, rate := range all {
        fmt.Printf("%s: %.1f%%\n", code, rate.Standard)
    }

    // When were EU rates last fetched?
    fmt.Println(euvatrates.DataVersion()) // "2026-03-27"

    // VAT number format validation — no API key, no network call
    euvatrates.ValidateFormat("ATU12345678") // → true
    euvatrates.ValidateFormat("DE123456789") // → true
    euvatrates.ValidateFormat("INVALID")     // → false

    // Access format metadata directly
    at, _ := euvatrates.GetRate("AT")
    fmt.Println(at.Format)   // "ATU + 8 digits"
    fmt.Println(at.Pattern) // "^ATU\\d{8}$"

    // Flag emoji from a 2-letter country code — no lookup table, computed from regional indicator symbols
    fmt.Println(euvatrates.GetFlag("FI")) // "🇫🇮"
    fmt.Println(euvatrates.GetFlag("DE")) // "🇩🇪"
    fmt.Println(euvatrates.GetFlag("XX")) // "" (empty string for unknown/invalid codes)
}

Data source & update frequency

• EU-27 rates: European Commission TEDB, refreshed daily at 07:00 UTC
• Non-EU rates: maintained manually, updated on official rate changes
• New git tag + pkg.go.dev version published only when rates change

---

Keeping rates current

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.

Need real-time accuracy? Fetch the always-current JSON directly:

https://cdn.jsdelivr.net/gh/vatnode/eu-vat-rates-data@main/data/eu-vat-rates-data.json

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

Need to validate VAT numbers?

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.

curl https://api.vatnode.dev/v1/vat/FI17156132 \
  -H "Authorization: Bearer vat_live_..."
# → { "valid": true, "companyName": "Suomen Pehmeä Ikkuna Oy" }

Changelog

2026-04-25

• fix: Corrected Sweden (SE) VAT number regex — was ^SE\d{12}$, now correctly requires the mandatory 01 suffix: ^SE\d{10}01$.
