The US Tax Rates API provides access to detailed breakdowns of various tax categories, including state income tax, sales tax, property tax rates, and total tax burden for each U.S. state.
You can retrieve tax data for a specific state by using the appropriate endpoint provided by the API, which allows you to filter results based on the state you are interested in.
Yes, the US Tax Rates API enables users to compare tax rates across different states by exposing endpoints that allow for side-by-side comparisons of various tax categories.
The API is ideal for researchers, developers, and analysts who need structured and filterable access to public tax data for analysis, application development, or research purposes.
Each endpoint returns specific tax-related data for U.S. states. For example, the income tax endpoint returns minimum and maximum income tax rates, while the property tax endpoint provides the property tax rate for a specified state.
Key fields in the response data include "state," "income_tax_minimum_rate," "income_tax_maximum_rate," "property_tax_rates," and "sales_tax." These fields provide essential information about tax rates for the specified state.
The primary parameter for each endpoint is the "state," which must be specified to retrieve relevant tax data. Users can obtain a list of states from the "us states listing" endpoint to use as input for other endpoints.
The response data is structured in JSON format, with each response containing a "state" field followed by specific tax-related fields. This organization allows for easy parsing and integration into applications.
Typical use cases include tax analysis, financial planning, and application development. Researchers may use the data to study tax trends, while developers can integrate it into financial software or tax calculators.
The data is sourced from authoritative datasets, ensuring high accuracy. Regular updates and quality checks are implemented to maintain the reliability of the tax information provided through the API.
Each endpoint provides specific tax information: income tax rates, property tax rates, sales tax rates, and average annual property tax. This allows users to access a comprehensive view of state tax structures.
Users can utilize the returned data by integrating it into applications for tax calculations, comparisons, or reporting. The structured JSON format allows for straightforward data manipulation and display in user interfaces.

To obtain your API key, you first need to sign in to your account and subscribe to the API you want to use. Once subscribed, go to your Profile, open the Subscription section, and select the specific API. Your API key will be available there and can be used to authenticate your requests.
You can’t switch APIs during the free trial. If you subscribe to a different API, your trial will end and the new subscription will start as a paid plan.
If you don’t cancel before the 7th day, your free trial will end automatically and your subscription will switch to a paid plan under the same plan you originally subscribed to, meaning you will be charged and gain access to the API calls included in that plan.
The free trial ends when you reach 50 API requests or after 7 days, whichever comes first.
No, the free trial is available only once, so we recommend using it on the API that interests you the most. Most of our APIs offer a free trial, but some may not include this option.
Yes, we offer a 7-day free trial that allows you to make up to 50 API calls at no cost, so you can test our APIs without any commitment.
Zyla API Hub is like a big store for APIs, where you can find thousands of them all in one place. We also offer dedicated support and real-time monitoring of all APIs.

But if you subscribe to multiple ones, you'll use the same key for all of them, making things easier for you.
