About Us
Easy Sales Tax Calculator is a free tool for calculating US sales tax across all 50 states, built to be fast, accurate, and genuinely useful for shoppers, sellers, and small businesses.
What we do
We provide instant sales tax calculations for every US state, plus city-level rates for major metros. Whether you're an online seller figuring out what to charge, a shopper checking a receipt, or a small business owner estimating tax on an invoice, our calculators give you the combined state and local rate in seconds — no signup, no cost.
Why we built it
US sales tax is deceptively complicated. Rates change at the state, county, and city level, and official information is scattered across dozens of government websites. We built Easy Sales Tax Calculator to put trustworthy, up-to-date rates in one place — and to be transparent about where those numbers come from.
How we verify our rates
This is what sets us apart from most automated tax tools. Our rates are checked against official state Department of Revenue (DOR) sources — the government agencies that actually set and publish the numbers — not just aggregated from third parties.
- Official primary sources. We reconcile our data against each state's tax authority, including the Texas Comptroller, the New York State Department of Taxation and Finance, the North Carolina DOR, the Hawaii Department of Taxation, and the tax divisions of every other state.
- Monthly review cadence. We re-check rates on a rolling monthly schedule and log every correction. Our most recent full verification pass was completed in April 2026.
- Cross-checking. Where a local rate is ambiguous, we corroborate the DOR figure against municipal sources before publishing a change, and we record the reasoning.
Limitations & honesty
Sales tax rates change, and jurisdictions occasionally adopt new local taxes between our review cycles. We work hard to keep rates current, but our calculators are provided for informational and estimation purposes only and are not a substitute for professional tax advice or the official rate published by your state or locality. For anything with legal or financial consequences, confirm with the relevant Department of Revenue or a qualified tax professional. See our Terms of Use for details.
