eu-vat

The standard VAT rate in every EU member state on any date since 1 January 2016, as small libraries with no dependencies that work offline.

import { getStandardRate } from '@duty27/eu-vat';
getStandardRate('DE', '2020-07-01');   // 16 (Germany's temporary cut)

from duty27_eu_vat import get_standard_rate
get_standard_rate("DE", "2020-07-01")  # Decimal('16')

EuVat.getStandardRate("DE", "2020-07-01");   // 16

All three give identical answers (so does the MCP server) and are built from the same dataset, which Duty27 publishes at https://duty27.com/vat-rates/history, as CSV and JSON at https://duty27.com/data/eu-standard-vat-rates.json. Every rate change there cites the law or tax-authority notice that made it, and the 2016 starting rates cite the European Commission's rate table; the citations are on that page and in the CSV and JSON, not in the packages. It covers standard rates only; reduced rates are not included. It looks rates up; it does not calculate tax. This is information, not tax advice.

For deciding what to charge (B2B reverse charge, the EU €10,000 threshold, VIES checks) and keeping the proof (archive and OSS reports), see the Duty27 API, which is free to try.

Taking just the one you need

Most people never need this repository: install the package from its registry. To read or work on one library, each folder is self-contained: it has its own README, licences, build file and tests, and needs nothing from the rest of the repo. To fetch only one folder instead of the whole repository:

git clone --filter=blob:none --no-checkout https://github.com/duty27/eu-vat.git
cd eu-vat
git sparse-checkout set python        # or node, or java
git checkout main

How they stay identical

One file, data/eu-standard-vat-rates.json, is the source. ./build.sh turns it into each language's data module and a shared set of expected answers (test-vectors.csv, worked out by a plain scan of the data, not by any library), then builds and tests all three libraries and the MCP server (which bundles the Node library's data), and finishes by checking that every one of them carries the same source hash.

./build.sh            # regenerate the data, then build and test node, python, java and the MCP server
./build.sh java       # one language (or node, python, mcp)
./build.sh refresh    # fetch the published rates and update the snapshot
./build.sh check      # fail if the published rates changed, or a generated file was edited by hand
