Free Sales Tax Rates for Developers
Our Tax Rates API is an easy way for you to use sales tax rates in your project. Our API is powered by our tax rule content, and rates are updated as tax rules change to stay current. You can use this API to:
- Get the sales tax rate for a five digit zip code in the United States
- Get the sales tax rate for a specific street address in the United States
Avalara is an online tax filing solution that integrates with QuickBooks, MSDun, Magento, 3dcart, and others. The Avalara Tax Rates API will accept country and postal codes as inputs to retrieve the corresponding sales tax rate for an area. The API can also accept an address along with the country, state, and zip code in order to determine a specific location's tax rates. The Tax Rates API returns a JSON response that lists individual jurisdictions, a summary, and the corresponding tax rates returned as decimal equivalents to percentages. The Avalara Tax Rates API has a limit of 15 tax rate requests per minute.
The following is a list of libraries from ProgrammableWeb's Library Directory that matched your search term. Although there many different interpretations of the word "library" among software developers, ProgrammableWeb adheres to a specific definition so as to clearly distinguish libraries from SDKs and frameworks in a way that will facilitate clean search results. In ProgrammableWeb's parlance, the term "library" is strictly used to describe a platform-specific software tool that, when installed, results in the provisioning a specific API. Conversely, SDKs are exclusively for consuming APIs and Frameworks are agnostic to specific APIs. If you think a library, SDK, API, or other asset is missing from our directory, be sure to check our guidelines for making contributions to ProgrammableWeb.
