United States · state-tax triage
Sales-tax nexus screening.
Flag common facts that may create a state sales-tax registration or collection question. This is a triage screen, not a 50-state threshold calculator.

Check the facts that apply to your business.
Why this stops at screening
States differ on economic thresholds, taxable products and services, marketplace-facilitator rules, registration timing, filing frequency and local taxes. The Supreme Court’s South Dakota v. Wayfair decision did not create one national threshold. Use the flags above to identify where to read the state’s current rule, then document the facts and sales totals that rule asks for.
No state conclusion
A checked box does not prove that nexus exists, and an unchecked box does not prove that it does not. Confirm with the relevant state tax agency or a tax professional.
