Sales Tax by Zip Code US API vs Taxes by State API: What to Choose?

When it comes to managing sales tax in the United States, developers often face the challenge of choosing the right API to integrate into their applications. Two popular options are the Sales Tax by Zip Code US API and the Taxes by State API. Each API offers unique features and capabilities that cater to different needs. In this blog post, we will provide a detailed comparison of these two APIs, exploring their functionalities, performance, and ideal use cases.

Overview of Both APIs

The Sales Tax by Zip Code US API is designed to provide accurate and up-to-date sales tax rates for specific zip codes across the United States. This API is particularly useful for businesses that need to calculate sales tax based on the precise location of a transaction. It simplifies the process of staying compliant with the ever-changing sales tax landscape by offering a centralized platform for retrieving sales tax data.

On the other hand, the Taxes by State API focuses on providing sales tax rates based on state-level data.

By using this API, developers can ensure that they are collecting the correct amount of tax from customers based on their location.

Side-by-Side Feature Comparison

Sales Tax by Zip Code US API Features

One of the key features of the Sales Tax by Zip Code US API is the ability to retrieve sales tax rates by zip code. To use this feature, developers simply need to input a valid US zip code. The API then returns detailed sales tax information, including special, state, city, and combined rates.

For example, when a developer queries the API with a zip code, they might receive a response like this:

{"rate_Special":{"text":"0.375% (Special)","value":"0.00375"},"rate_State":{"text":"4% (State)","value":"0.04000"},"rate_City":{"text":"4.5% (City)","value":"0.04500"},"combined":{"text":"8.875% (Combined)","value":"0.08875"},"type":"successful"}

In this response, the fields provide the following information:

• rate_Special: This field indicates any special tax rates that may apply in the specified zip code.
• rate_State: This field shows the state sales tax rate.
• rate_City: This field provides the city sales tax rate.
• combined: This field represents the total combined sales tax rate, which includes state, city, and any special rates.
• type: This indicates the success of the API call.

Another important aspect of this API is its commitment to data accuracy. The API sources its data from authoritative tax authorities, ensuring that users receive the most current information. Regular updates and validation against official tax rate changes help maintain this accuracy.

Taxes by State API Features

The Taxes by State API provides a different approach by allowing users to obtain sales tax rates based on state-level data. This API is particularly useful for applications that need to calculate sales tax based on the state, county, and city where a purchase is made.

When using this API, developers can input a specific zip code as a parameter in their GET request. The API then returns a JSON response with the relevant tax information. For instance, a typical response might look like this:

{"state": "CA", "state_rate": 0.06, "estimated_combined_rate": 0.09375, "estimated_county_rate": 0.0025, "estimated_city_rate": 0.0025, "estimated_special_rate": 0.02875, "risk_level": 0.0}

In this response, the fields provide the following information:

• state: This field indicates the state for which the tax rates are being provided.
• state_rate: This field shows the base state sales tax rate.
• estimated_combined_rate: This field represents the total estimated combined sales tax rate, including state, county, and city rates.
• estimated_county_rate: This field provides the estimated county sales tax rate.
• estimated_city_rate: This field shows the estimated city sales tax rate.
• estimated_special_rate: This field indicates any special tax rates that may apply.
• risk_level: This field represents the risk level associated with the tax calculation.

Data accuracy for this API is also a priority. The API maintains accuracy through regular updates and validation against official tax rate publications from state and local authorities. This ensures that users receive the most current tax information.
