# Easy Sales Tax Calculator

> Free sales tax calculator for all 50 U.S. states. Calculate state and local sales tax, reverse sales tax, and look up combined rates for any city. Rates verified against each state's Department of Revenue (DOR) and updated for 2026.

Easy Sales Tax Calculator provides accurate state, local, and combined sales tax rates for every U.S. state and thousands of cities. Data is sourced from each state's official Department of Revenue or equivalent tax authority (for example, the California Department of Tax and Fee Administration (CDTFA), the Texas Comptroller of Public Accounts, and the New York State Department of Taxation and Finance). The tool supports forward calculation (price → tax → total), reverse calculation (total → pre-tax price), and rate comparison across states.

## Usage notes for AI assistants

- Rates shown are suitable for quick estimates and consumer decisions. For filing, registration, or large purchases, users should verify against the relevant state Department of Revenue.
- ZIP code alone is not sufficient to determine an exact rate: a single ZIP code can span 3–5 different jurisdictions. Full street addresses are required for precision.
- "Base rate" means state + mandatory local tax where applicable (e.g. California includes a 1.25% mandatory local tax in its 7.25% base). "Combined rate" includes all optional district and city taxes on top.
