Terms of Service

Last updated: October 2026

1. Estimates for Educational and Informational Purposes

All calculations and rate tables on the USA Sales Tax Calculator are estimates intended for educational and informational purposes only. State base rates, county add-ons, city taxes, and special-district surtaxes are compiled from public sources and updated periodically for accuracy, but they can change at any time.

2. Local Rates Change Periodically

Local rates and municipal surtaxes change periodically — often quarterly or annually — and combined rates vary by exact street address. Always confirm the applicable rate with your state department of revenue or local tax authority before completing a purchase, filing a return, or setting prices for your business.

3. Not Legal, Financial, or Tax Advice

Figures produced by this tool should not be considered certified legal, financial, or tax advice. For binding guidance on nexus, exemptions, filing obligations, or audits, consult a licensed tax professional or attorney in your jurisdiction.

4. Acceptable Use

• Use the calculator for lawful, personal, or business estimation only.
• Do not attempt to disrupt the site, scrape it abusively, or misrepresent its output as an official tax ruling.
• All content and rate compilations are provided "as is" without warranties of any kind.
