Frequently Asked Questions

  • Yes, but you must have a premium subscription. Commercial use of the Property 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.
  • The Property Tax API is ideal for real estate platforms, mortgage and lending tools, relocation calculators, and investment analysis apps that need effective property tax rates across U.S. locations. It pairs well with our Sales Tax API and Income Tax API for building complete cost-of-living or tax-burden comparisons.
  • Send a GET request to /v1/propertytax with at least one of city, county, or zip set, optionally narrowing results with state (a 2-letter abbreviation or the full state name). Values are not case-sensitive, zip also accepts ZIP+4 codes, and county works with or without the word County or Parish. You can find ZIP codes and counties using our Zip Code API and County API.
  • Each result is a JSON object with location fields (state, county, city, zip) plus three effective property tax rates: property_tax_25th_percentile, property_tax_50th_percentile (median), and property_tax_75th_percentile. Rates are returned as decimals (for example, 0.0104363 is about 1.04 percent), and unsuccessful requests return an error instead.
  • Each result is one tax region, identified by its ZIP code, county and city. A ZIP code can return more than one row where several jurisdictions apply, and the API returns a maximum of 100 results per request. For higher volume needs across many locations, see our pricing plans.
