About Us

We are building the internet's fastest, most accurate tax engine.

SalesTaxZip.com was born from a simple frustration: why are tax calculators so slow, ugly, and riddled with pop-ups?

Our Database

We maintain a real-time dataset of over 40,000+ US tax jurisdictions. This includes state-level levies, county surtaxes, and city-specific add-ons. Our goal is to empower freelancers, developers, and small business owners with the data they need to stay compliant.
