What it does
A tax engine built for checkout
Fast enough to sit inline when your customer pays, precise enough to stand up in an audit.
Rooftop-accurate US rates
Addresses resolved to the exact jurisdictions they sit in, not approximated from a ZIP code that can span several tax districts.
Product taxability
Clothing, groceries, books, digital goods and SaaS taxed by each state’s and country’s rules, including reduced and zero rates.
B2B and reverse charge
EU and UK VAT numbers checked at checkout, with reverse charge applied automatically when it is due.
Marketplace-aware
No tax charged twice on sales where Amazon, Etsy or another marketplace already collects it.
Real time
Calculated as the customer checks out, through your integrations or the GoodVat API.
Audit trail
Every calculation stored with the rule and rate applied, ready when an auditor asks why.

Frequently asked questions
Why not just use a sales tax rate by ZIP code?
Because one ZIP code can cover several tax jurisdictions with different rates. GoodVat resolves the customer’s address to the exact city, county and special district it sits in, which is how states expect tax to be calculated.
Does GoodVat handle products with special tax rules?
Yes. You give each product a category, such as clothing, groceries, books, digital goods or SaaS, and GoodVat applies the rules of each state or country you sell to, including exemptions, reduced rates and price thresholds.
How does reverse charge work?
When an EU or UK business customer gives a valid VAT number on a cross-border sale, the customer accounts for the VAT instead of you. GoodVat validates the number at checkout, charges 0% and adds the reverse charge wording to the invoice.
How do I connect the tax engine?
Through one of GoodVat’s integrations for stores, payment providers and billing systems, or directly through the GoodVat REST API from a custom checkout.
Can I check a rate without signing up?
Yes. The free US sales tax calculator shows the combined rate at any US address, broken into state, county, city and district, and the VAT calculator covers the UK and EU.
