2026 State Sales Tax Rates — Reference Table
State base rates plus average local add-ons, from Tax Foundation midyear 2026 data (as of July 1, 2026). Your exact combined rate depends on your city and county — the calculator above lets you override the local rate.
| State | State rate | Avg. local | Avg. combined |
|---|
Five states have no statewide sales tax: Alaska, Delaware, Montana, New Hampshire, Oregon. Local taxes can still apply in Alaska. California's 7.25% includes its 1.25% mandatory statewide local add-on; the same applies to Utah (1.25%) and Virginia (1%). New Jersey's average local rate is slightly negative because Salem County collects a reduced 3.3125% rate instead of the statewide rate. This table is for estimation only and is not tax advice.
How US Sales Tax Works
Unlike the VAT systems used in most of the world, the United States has no national sales tax. Instead, each state sets its own base rate, and counties and cities can add their own local rates on top. That is why the same $100 item can cost $100 in Oregon and about $110 in Louisiana: the tax is not one number but a stack of rates that depends on exactly where the purchase happens.
State Rate vs Combined Rate
The state rate is the base every seller in the state must charge. The combined rate adds the average local taxes for that state — useful for a quick estimate, but your real rate at a specific address can be higher or lower. New York is the classic example: the state rate is only 4%, but New York City's combined rate is 8.875% once city and transit taxes are added. The calculator shows both parts separately, and lets you type in your exact local rate when you know it.
Reverse Mode: Finding the Pre-Tax Price
Ever seen a total on a receipt and wondered what the item itself cost? Reverse mode divides the tax-inclusive total by one plus the combined rate, giving you the original price and the tax portion. Small sellers use this to check supplier invoices; shoppers use it to compare prices across states.
What About Groceries and Clothing?
Many states exempt groceries from sales tax or tax them at a reduced rate, and a few exempt clothing below a price threshold. These exemptions vary by state and change from time to time, so the calculator applies the general rate — if your purchase is food or clothing, check your state's current exemption rules before relying on the result.
Why a Dated Table Matters
Sales tax rates change: Louisiana raised its state rate from 4.45% to 5% in January 2025, and several states changed grocery rules in 2025–2026. A calculator with an undated, mystery table can quietly go stale. Every rate on this page is stamped to Tax Foundation's midyear 2026 data (July 1, 2026) and will be refreshed when new data lands.
Frequently Asked Questions
How is US sales tax calculated?
Multiply the pre-tax price by the combined rate (state rate + local rate). For example, a $100 item in California at 7.25% state rate costs $107.25 before any city or district add-ons.
Why does the same item cost different tax in different states?
Because each state sets its own rate and local governments add their own. Five states — Alaska, Delaware, Montana, New Hampshire and Oregon — have no statewide sales tax at all.
What is the difference between the state rate and the combined rate?
The state rate is the base rate for the whole state. The combined rate adds average local taxes, which is the number most shoppers actually pay. Your exact rate depends on your city and county.
How do I reverse-calculate the pre-tax price?
Switch to Reverse mode, enter the total including tax, and pick your state. The calculator divides by one plus the combined rate to recover the original price and the tax portion.
Are groceries and clothing taxed?
It depends on the state. Many states exempt groceries or tax them at a reduced rate, and some exempt clothing under a price limit. Check your state's current rules for those categories.
Is this calculator free, and is it tax advice?
Yes, it is free with no signup, and it runs entirely in your browser. It is an estimation tool, not tax advice — verify rates with your state department of revenue before filing anything.
