Overview

The US Sales Tax Data Retrieval API is designed to provide an accurate and reliable solution for calculating taxes on each transaction. Its main objective is to simplify the country's complex tax structure, where taxes vary not only at the state level, but also at the city and county levels, with additional rates that may apply depending on location.

By providing a zip code as a parameter, the API returns a complete breakdown of the applicable tax rates. These include the state rate, city rate, county rate, and any additional rates in effect, along with the total combined percentage. In addition, it not only provides the percentages, but also calculates the monetary amounts corresponding to each tax component, allowing you to clearly see how much you are paying at each level.

Another key feature is the ability to calculate the final price of a product or service by automatically adding taxes to the tax base. This is especially useful for e-commerce platforms, financial applications, marketplaces, or any technology solution that needs to display final prices with taxes included in a transparent manner to the consumer.

The API is designed to be fast, accurate, and easy to integrate. Its JSON response structure makes it compatible with multiple programming languages and development environments, facilitating incorporation into existing systems without the need for complex processes. It is also ideal for companies operating in multiple states, as it automates a process that would otherwise involve reviewing updated tax tables and manual calculations.

In an environment where tax accuracy is critical for regulatory compliance and customer trust, this API becomes an essential tool. Its implementation helps reduce human error, streamlines billing processes, and ensures that final prices accurately reflect the tax obligations applicable to each transaction within the United States.

US Sales Tax Data Retrieval API FAQs

The Sales Tax Calculator endpoint returns detailed sales tax information, including state, city, county rates, any additional rates, and the total combined tax percentage. It also calculates the monetary amounts for each tax component and provides the final price of a product or service after tax.

Key fields in the response include "state_rate," "city_rate," "county_rate," "additional_rate," "total_tax_percentage," "tax_amounts," and "final_price." These fields provide a comprehensive breakdown of applicable taxes and the total cost.

The primary parameter for the Sales Tax Calculator endpoint is "zip_code." Users can customize their requests by providing different zip codes to retrieve tax data specific to various locations across the United States.

The response data is structured in JSON format, organized into key-value pairs. Each tax component is clearly labeled, allowing users to easily identify state, city, county rates, and the final price, facilitating straightforward integration into applications.

The data is sourced from official state and local tax authorities, ensuring accuracy and reliability. The API regularly updates its data to reflect any changes in tax rates or regulations, maintaining high-quality information.

Typical use cases include e-commerce platforms calculating final prices for customers, financial applications ensuring compliance with tax regulations, and marketplaces displaying transparent pricing. The API simplifies tax calculations for businesses operating in multiple states.

Users can utilize the returned data by integrating it into their applications to display accurate tax calculations and final prices. By parsing the JSON response, developers can extract specific tax components and present them clearly to end-users.

If the API returns partial or empty results, users should check the provided zip code for accuracy. Implementing error handling in the application can help manage such scenarios, allowing for fallback options or user notifications when tax data is unavailable.

Once subscribed, return to the API page and you will see your API Access Key displayed at the top of the documentation page. You can use this key to authenticate your requests.

The free trial lasts for 7 days and allows you to make up to 50 API requests.

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. Once you sign up, you can pick and choose which APIs you want to use. Just remember, each API needs its own subscription. But if you subscribe to multiple ones, you'll use the same key for all of them, making things easier for you.

Prices are listed in USD (United States Dollar), EUR (Euro), CAD (Canadian Dollar), AUD (Australian Dollar), and GBP (British Pound). We accept all major debit and credit cards. Our payment system uses the latest security technology and is powered by Stripe, one of the world's most reliable payment companies. If you have any trouble paying by card, just contact us at [email protected]

Additionally, if you already have an active subscription in any of these currencies (USD, EUR, CAD, AUD, GBP), that currency will remain for subsequent subscriptions. You can change the currency at any time as long as you don't have any active subscriptions.
The local currency shown on the pricing page is based on the country of your IP address and is provided for reference only. The actual prices are in USD (United States Dollar). When you make a payment, the charge will appear on your card statement in USD, even if you see the equivalent amount in your local currency on our website. This means you cannot pay directly with your local currency.
Occasionally, a bank may decline the charge due to its fraud protection settings. We suggest reaching out to your bank initially to check if they are blocking our charges. Also, you can access the Billing Portal and change the card associated to make the payment. If these does not work and you need further assistance, please contact our team at [email protected]
Prices are determined by a recurring monthly or yearly subscription, depending on the chosen plan.
API calls are deducted from your plan based on successful requests. Each plan comes with a specific number of calls that you can make per month. Only successful calls, indicated by a Status 200 response, will be counted against your total. This ensures that failed or incomplete requests do not impact your monthly quota.
Zyla API Hub works on a recurring monthly subscription system. Your billing cycle will start the day you purchase one of the paid plans, and it will renew the same day of the next month. So be aware to cancel your subscription beforehand if you want to avoid future charges.
To upgrade your current subscription plan, simply go to the pricing page of the API and select the plan you want to upgrade to. The upgrade will be instant, allowing you to immediately enjoy the features of the new plan. Please note that any remaining calls from your previous plan will not be carried over to the new plan, so be aware of this when upgrading. You will be charged the full amount of the new plan.
To check how many API calls you have left for the current month, refer to the 'X-Zyla-API-Calls-Monthly-Remaining' field in the response header. For example, if your plan allows 1,000 requests per month and you've used 100, this field in the response header will indicate 900 remaining calls.

You can monitor your API usage through the response headers included with every request:

x-zyla-api-calls-monthly-used: Shows the total number of API requests you have used during the current billing period.
x-zyla-api-calls-monthly-remaining: Shows the number of API requests you have remaining for the current billing period.

The 'X-Zyla-RateLimit-Reset' header shows the number of seconds until your rate limit resets. This tells you when your request count will start fresh. For example, if it displays 3,600, it means 3,600 seconds are left until the limit resets.

Yes, you can cancel your subscription at any time. Simply go to the Pricing section of the API you're subscribed to and click the "Unsubscribe" button.

Please note that upgrades, downgrades, and cancellations take effect immediately. Once your subscription is canceled, access to the service will end immediately, regardless of any remaining API calls in your quota.
