About Us

We care about sales tax so you don’t have to.

At TaxCloud, we eat sales tax for breakfast.

No one wants to talk about sales tax compliance — but with 11,000+ sales tax jurisdictions in the U.S. alone, it’s a crucial part of your business. We built TaxCloud to give growing companies the peace of mind that they are 100% compliant in each jurisdiction they do business.

Our platform is completely self-serve, but because we’re all human, our team of TaxGeeks is ready to help sort through any questions you have, whenever you have them. Person to person.
