US Sales Tax Calculator

US sales tax is uniquely complex - unlike VAT/GST, it is only collected at the point of final sale and rates vary by state, county, city, and special district. This tool covers all 50 states and DC with both the state rate and the average combined rate (state + local), based on Tax Foundation 2024–2025 data. Five states have no sales tax: Alaska, Delaware, Montana, New Hampshire, and Oregon (NOMAD states).

Common Mistakes to Avoid

  • Using only the state rate and ignoring local rates - combined rates can be 2–5% higher
  • Not tracking economic nexus thresholds in each state
  • Applying sales tax to exempt items (groceries, medicine, clothing in some states)

Best Practices

  • Use combined rates for consumer-facing prices to avoid undercharging
  • Monitor your economic nexus thresholds in each state quarterly
  • Apply for sales tax exemption certificates where applicable

Why use this tool?

After South Dakota v. Wayfair (2018), online sellers must collect sales tax in states where they have economic nexus - typically $100K in sales or 200 transactions. Get it right to avoid penalties.

Frequently Asked Questions

Five states have no state sales tax: Alaska, Delaware, Montana, New Hampshire, and Oregon (often remembered as NOMAD). However, Alaska allows local jurisdictions to levy their own sales tax.
