How TaxCloud Works

Next
Built with

TaxCloud is a sales tax compliance service designed to make U.S. sales tax simple for businesses of any size. Our technology automatically calculates tax at checkout, files returns with 100% accuracy, and even supports audit management when needed.

This guide is for developers who want to integrate TaxCloud with an e-commerce system, order management system, point of sale system, or any other invoice or transaction management platform that needs to calculate sales tax (or manage exemption certificates for exempt purchasing entities) using TaxCloud’s v1 API.

Before getting started, you should check our Partner Integrations area to see if the platform you are targeting has already been implemented.

If you’re looking for general setup help, account managemeent, or filing guidance, please visit our main TaxCloud Support area. The Developer center is intentionally technical and focused on implementation.

What TaxCloud Provides

TaxCloud consists of two parts that work together:

  1. APIs — endpoints for calculating tax, completing orders, handling returns, and managing exemptions. These can be called by e-commerce systems, marketplaces, ERP software, or POS systems.
  2. The TaxCloud web app — where you configure account settings (such as where to collect tax), view transaction records, and access automatically generated sales tax reports with full jurisdictional detail.

Together, these let you calculate, collect, report, and remit sales tax with minimal operational effort.

API Endpoints

  • SOAP/XML clients access our TaxCloud API endpoint: SOAP here. SOAP/XML WSDL is available at SOAP reference here

  • JSON/REST clients access our TaxCloud API endpoint: JSON reference

  • method is the TaxCloud API method to call. For example the url to execute the Ping method is found in the reference here

Conclusion

With TaxCloud, you don’t need to worry about rates, jurisdictions, or compliance complexity—our APIs and web app handle the heavy lifting so you can focus on your business. This overview gave you the high-level picture of what TaxCloud provides and how it fits into your platform.

From here, you can:

  • Explore the API reference for detailed method documentation.
  • Review integration guides to see if your platform already supports TaxCloud.
  • Send an email to [service@taxcloud.net] for questions relating to account setup, filing, and compliance resources.

When you’re ready, continue with the How TaxCloud Works section to see the basic order flow (VerifyAddress → Lookup → Order Completion → Returned).
