Why founders dread sales tax

US sales tax is complicated. 50 states, thousands of jurisdictions, and constantly changing rules create a compliance minefield.

Economic Nexus

Simply selling enough into a state can trigger tax obligations, even without a physical presence. Tracking these thresholds manually is impossible.

12,000+ Jurisdictions

Rates vary by state, county, city, and district. You need to calculate the exact rate for every single customer address in real-time.

Filing Deadlines

Different states have different filing frequencies (monthly, quarterly, annual). Missing a deadline results in hefty penalties and interest.
