Terms of Service

Last updated: September 25, 2026

⚠️ IMPORTANT TAX DISCLAIMER

Sails provides TAX ESTIMATION TOOLS and FILING PREPARATION ASSISTANCE ONLY. We are NOT a certified public accounting (CPA) firm, tax advisory service, or law firm. Our tools are designed to assist with sales tax calculations and generate filing-ready reports, but should not be relied upon as the sole basis for tax compliance decisions.

Filing Assistance: We prepare reports and pre-fill data to help you file, but YOU are responsible for reviewing all information and submitting your own tax returns. We do NOT file returns on your behalf, and we do NOT hold or remit any tax funds.

You are solely responsible for:

  • Verifying the accuracy of all tax calculations
  • Ensuring compliance with applicable tax laws
  • Filing accurate tax returns
  • Consulting qualified tax professionals for advice specific to your situation

Tax rates, rules, and exemptions change frequently. We make reasonable efforts to maintain accurate data, but we cannot guarantee that our rates are current or complete. Local taxes (city, county, special districts) may apply and are not always reflected in our calculations.

1. Acceptance of Terms

By accessing or using Sails ("the Service"), you agree to be bound by these Terms of Service ("Terms"). If you do not agree to these Terms, do not use the Service. We may modify these Terms at any time, and your continued use of the Service after such modifications constitutes acceptance of the updated Terms.

2. Description of Service

Sails provides:

  • Sales tax calculation tools for US states and territories
  • Product category-based tax rate estimation
  • Nexus determination assistance
  • Filing deadline tracking
  • Integration with e-commerce platforms
  • Tax calculation history and reporting

The Service is provided "as is" and is intended to assist with sales tax compliance, not replace professional tax advice.

3. User Responsibilities

You agree to:

  • Provide accurate and complete information when registering
  • Maintain the security of your account credentials
  • Notify us immediately of any unauthorized access
  • Use the Service only for lawful business purposes
  • Not attempt to reverse engineer, hack, or disrupt the Service
  • Verify all tax calculations before filing returns
  • Keep your own records for tax compliance purposes
  • Comply with all applicable laws and regulations

4. Tax Rate Accuracy

Important: Tax rates in our system are estimates based on publicly available data.

Regarding our tax rate data:

  • Sources: The calculator uses each state's rate plus the average local rate published by the Tax Foundation; nexus thresholds come from state sources summarized by the Sales Tax Institute. Each page shows when its data was last reviewed.
  • Updates: We update rates when the Tax Foundation publishes new averages (twice a year) and review nexus rules regularly, but changes may not be immediate
  • Local Taxes: Average local rates are estimates — the actual city, county, and special district rate at a specific address can be higher or lower
  • Exemptions: Product exemptions are simplified and may not cover all scenarios
  • Verification: Always verify rates with official state tax authority websites

Links to official state tax authorities can be found on our Calculator page.

5. Limitation of Liability
