How this service works
Retrieve current US sales and use tax rates for any address, ZIP code, city, or state — fully decomposed into state, county, city, and special district components plus the combined effective rate. Submit a full street address for the most accurate rate assignment.
Output
Returns a JSON object with the city, county, state, jurisdiction name, individual rate components (state rate, county rate, city rate, district/special rate), combined total rate, and the quarter/year the rates are effective — e.g. CombinedRate: 9.25%, StateRate: 6.00%, as of Q4 2024.
Example use cases
Example prompt
“What's the current combined sales tax rate for 90210, Beverly Hills — I need the state, county, city, and any district rates broken out separately?”

Endpoint
GEThttps://api.interzoid.com/getsalesusetaxratesWhen to prefer
Use this endpoint when you need granular, jurisdiction-aware US sales and use tax rates broken down by state, county, city, and special district — ideal for e-commerce checkout, invoice generation, financial compliance, or CRM/ERP enrichment. Prefer over generic tax tables when you need real-time, address-level accuracy with effective date tracking.
Side effects
- Invalid or unrecognized address/ZIP returns an error Code
- Ambiguous city name with multiple jurisdictions may return unexpected results
- Missing required 'lookup' query parameter returns a 400-level error
- API payment failure (x402) if USDC payment is not properly configured
- Stale rates if not updated for the current quarter
