Sales & Use Tax Rate API
Pull accurate, jurisdiction-level sales and use tax rates for any U.S. address. Three precision levels. JSON and XML. Real-time.
How It Works
What the API does
Your system sends a request with a ZIP or address, and the API returns the current sales and use tax rates for that jurisdiction.
Response formats
XML and JSON, both supported.
Precision levels
Three precision levels available depending on subscription tier.
Precision Levels
LEVEL 1
Basic (5-digit ZIP)
Returns all jurisdictions tied to a ZIP. May return multiple results if the ZIP crosses jurisdiction lines.
Best for: General estimates. Fastest and most affordable.
LEVEL 2
SalesTax+4
Narrows to the 9-digit ZIP for single-
jurisdiction certainty at county and city
level.
Best for: Best balance of accuracy and cost.
LEVEL 3
Spot-On (Full Address)
Geolocates the full street address. Catches
special tax districts that ZIP boundaries
miss.
Best for: Highest accuracy. Required for rooftop-level precision.
