State sales tax base rates for 2026 range from 0% in five states, Alaska, Delaware, Montana, New Hampshire, and Oregon, to 7.25% in California, according to the Tax Foundation's 2026 state sales tax rate table (data as of January 1, 2026, page updated April 2, 2026). Most states fall between 4% and 7%. That base rate is only part of what shoppers pay: county, city, and special-district taxes typically add another 1 to 5 percentage points, so average combined rates run from 0% in the no-tax states to around 9.5% in states like Tennessee and Louisiana. The full table below lists every state's verified base rate alongside ZipCodeSalesTax's own average combined rate estimate. Alaska is the exception among the no-tax states: it has no statewide sales tax, but some municipalities impose their own local rate.

State base rates are cross-checked against the Tax Foundation's "State Sales Tax Rates, 2026" table (data as of January 1, 2026; page updated April 2, 2026), with a sample of state figures, including California and Texas, independently verified directly against the state's own revenue agency this session. The average combined rate column is ZipCodeSalesTax's own model: the state base rate plus a typical county, city, and special-district add-on for that state, used by this site's calculators since they launched. It is an estimate for budgeting and quick receipt checks, not an address-level lookup. This table was last checked against primary sources on July 2, 2026, and none of the ten-plus states sampled required a correction; all matched the site's existing figures. Because local sales tax rates change more often than state base rates, always confirm the exact combined rate for a specific address with your state's department of revenue before filing or remitting.
https://zipcodesalestax.com/sales-tax-by-stateLouisiana, Tennessee, Arkansas, Washington, and Alabama consistently rank highest for average combined rates, often above 9%. In each case, substantial local add-ons push the total well above what the state base rate would suggest.
Setting aside the five no-tax states, Wyoming, Wisconsin, and Maine tend to have the lowest combined rates, typically in the 5 to 6% range, partly because each limits how much local jurisdictions can add on top.
The state rate is only part of what you owe. County and city taxes layer on top, so two addresses a block apart can carry different combined rates. Use the ZIP code tool for a quick average, then verify with your state tax authority before filing.
The calculator turns any U.S. ZIP code and a dollar amount into an estimated combined tax.
Alaska, Delaware, Montana, New Hampshire, and Oregon have no state-level sales tax. Delaware, Montana, New Hampshire, and Oregon also have no local sales taxes. Alaska has no state tax but some municipalities charge local taxes.
Tennessee and Louisiana consistently rank highest for average combined sales tax rates, often above 9.5%, because their local jurisdictions add significant amounts on top of already substantial state rates.
California's state sales tax rate is 7.25%, the highest state base rate in the country. Combined with county and city taxes, most California residents pay between 8% and 10.75%, depending on their exact address.
Yes. Florida's state sales tax rate is 6%, and most counties add a discretionary surtax of 0.5% to 1.5%. The average combined rate in Florida is around 7%, though it varies by county.
