VAT & Sales Tax API
VAT, GST and sales-tax rates for 128 countries — plus US state and Canadian province sub-rates — with a built-in tax calculator. Get the standard rate for any country (e.g. DE → 19%), compute the tax and gross total on a net amount (e.g. €100 in Germany → €19 tax, €119 total), apply a US state or Canadian province rate, or list every country. Ideal for e-commerce checkouts, invoicing, SaaS billing and pricing tools. (Standard rates, not tax advice.)
