Frequently Asked Questions

  • Yes, but you must have a premium subscription. Commercial use of the Sales Tax API is not permitted on the free tier. See our pricing page to choose a plan that fits your needs.
  • Sign up for a free account to instantly get your API key, then pass it in the X-Api-Key header on every request. The documentation above includes ready-to-run examples in cURL, Python, JavaScript, Node.js, and more.
  • Your API requests will simply be denied once you hit your monthly quota — you will never be charged more than the plan you signed up for. To increase your quota, you can upgrade your plan any time on our pricing page.
  • The API responds with a standard HTTP status code and a JSON error message describing the problem. See our error codes reference for the full list of codes and how to resolve each one, or contact support if you need help.
  • Send a GET request to the /v1/salestax endpoint with exactly one of either a zip_code (a valid US ZIP code) or a city plus state combination; you can optionally add street_address alongside city and state for the most accurate lookup. To compute the actual tax on a purchase amount, pair it with the Sales Tax Calculator API.
  • The API returns a JSON array of breakdown objects with zip_code, state_rate, city_rate, county_rate, additional_rate, and total_rate (and street_address when you provide that parameter), with all values expressed as decimals (e.g. 0.0975 means 9.75%). Note that city_rate, county_rate, additional_rate, and total_rate are premium only fields.
  • It provides accurate, detailed sales tax breakdowns for every ZIP code, city, and state in the United States, separating state, county, city, and special district rates. For other tax types, see related APIs such as Income Tax, Property Tax, and the VAT Rates API for European Union rates.
  • The additional_rate field reflects special district sales taxes, and when a local government has multiple additional rates it contains the sum of all of them, which is then folded into the combined total_rate. Both fields are premium only.
