About this calculator

Quick sales-tax lookup for any US state at the state-level base rate. The actual rate you pay can be higher: most US states allow counties, cities, and special districts to layer additional rates on top — sometimes pushing the combined rate above 10% (Chicago combined ~10.25%, Los Angeles County 10.25% in most cities). This calculator gives the state base rate and lets you optionally type in your local add-on for an exact figure. Five states have no statewide sales tax: Alaska (local-only), Delaware, Montana, New Hampshire, and Oregon. Hawaii's "General Excise Tax" (GET) functions as a sales tax and is grouped here.

Frequently asked

Why do the rates differ from what I paid?+

The state-level base rate is only one piece. Counties, cities, transit districts, and tourism / mass-transit / business-improvement-district overlays can each add 0.25–4% on top. Use the optional local add-on field with the rate published by your specific city / county DOR page.

Is the rate the same for every product?+

No. Most states exempt or reduce the rate for groceries, prescription drugs, clothing (in PA, NJ, MA, MN, VT), and certain services. This calculator uses the general retail rate — verify product-specific rates with your state DOR.

Which states have no sales tax?+

Five — Alaska, Delaware, Montana, New Hampshire, Oregon. Alaska technically permits local sales taxes (rare; mostly tourist-area cities like Juneau and Anchorage Borough). The other four have no sales tax at any level.

How current is this table?+

2026 calendar-year rates per the Tax Foundation Annual State Sales Tax Rates report (January 2026 update). Rate changes mid-year happen rarely — check the relevant state DOR for breaking changes before quoting a customer.

Why doesn't the calculator include local rates automatically?+

Combined rates vary by exact street address; properly resolving them requires zip+4 lookups and ongoing data licensing. Free static tools can't reasonably cover ~13,000 sub-state jurisdictions. The optional add-on field is the workaround.
