Pick your home state, enter revenue, and select customer states to see the breakdown.
Quick tip: If you're a smaller business, you may not need to collect tax in every customer state. Switch to Advanced mode to check economic nexus thresholds per state.
About economic nexus: Most states only require you to collect sales tax once you exceed their revenue or transaction thresholds. This calculator flags states below nexus so you can focus on where you actually need to collect.
Disclaimer: This calculator uses population-weighted average combined state and local sales tax rates for 2026 from the Tax Foundation. Actual rates vary by city, county, and district. This estimate is for planning purposes only and is not tax advice. For exact rates and compliance requirements, consult a tax professional or your state's department of revenue.
