What This Skill Does
Looks up U.S. sales tax rates via the ZipTax API. Supports address, ZIP code, and lat/lng queries across 12,000+ jurisdictions. Returns total rates plus state, county, city, and district breakdowns, along with freight and service taxability flags.
Address-level lookups return a single exact rate rather than the multiple conflicting rates a ZIP code alone can produce.
When to use it
- Calculate sales tax for a customer checkout in a specific U.S. city
- Verify whether shipping charges are taxable in a given jurisdiction
- Get a jurisdiction breakdown for a multi-district address
- Look up tax rates by coordinates for a field service location
- Check account API usage against the monthly quota
