Sales Tax Calculator (2025–2026): Calculate State & Local Sales Tax for All 50 US States

The United States has no national sales tax; instead, retail transactions are governed by more than 13,000 state, county, municipal, and transit tax jurisdictions ranging from 0% in the five tax-free NOMAD states to 10.25%–11.45% in high-tax cities and parishes. Our Sales Tax Calculator lets you add state and local tax to any price, reverse-calculate the pre-tax cost from a tax-included receipt, or total multi-item bulk invoices in real time.

Forward vs. Reverse Sales Tax Formulas (With Worked Examples)

  • 1. Add Sales Tax to a Pre-Tax Price (Forward Checkout):
    Sales Tax = Pre-Tax Price × (Combined Rate ÷ 100)  |  Total Price = Pre-Tax Price + Sales Tax
    Example: Buying an $899.00 laptop in Nashville, Tennessee (7.00% state + 2.75% local = 9.75% combined): $899.00 × 0.0975 = $87.65 sales tax → $986.65 Total Price.
  • 2. Extract Pre-Tax Price from a Tax-Included Receipt (Reverse Tax):
    Pre-Tax Price = Tax-Included Total ÷ (1 + Combined Rate ÷ 100)  |  Tax Paid = Total − Pre-Tax Price
    Example: Auditing a $270.63 contractor receipt in Los Angeles (10.25% combined): $270.63 ÷ 1.1025 = $245.47 Pre-Tax Price and $25.16 Sales Tax. (Need a dedicated receipt-splitting tool? Use our Reverse Sales Tax Calculator.)

Key Sales Tax Exemptions & Business Compliance Tips

  • Always Combine State + County + City Rates: Entering Colorado’s 2.90% state base rate instead of Denver’s 8.81% combined rate underestimates tax by $591 on a $10,000 purchase.
  • Resale Certificates for Business Inventory: Retailers and e-commerce sellers buying wholesale goods for resale should issue a state Resale Certificate to suppliers so sales tax is collected only once from the final retail customer.
