What Changed in 2026
No state changed its base sales tax rate in 2026, but several made changes to what gets taxed and how local rates shifted.
- Illinois eliminated its 1% statewide grocery tax, though counties and cities can still impose their own local grocery taxes of up to 1%.
- Arkansas repealed state sales tax on groceries entirely. Local taxes on groceries still apply.
- California saw the largest combined rate increase (+0.19%) due to local rate changes, bringing it to 8.99%.
- Kansas was the only state with a notable rate decrease (-0.08%), dropping to 8.69%.
How Combined Rates Work
The rates shown above are averages. Your actual rate depends on your exact city, county, and any special taxing districts. A state like Louisiana has a 5.00% state rate, but local taxes push the average combined rate to 10.11%, the highest in the country. Meanwhile, five states collect no sales tax at all: Alaska, Delaware, Montana, New Hampshire, and Oregon. Alaska is a special case: it has no state-level tax, but many of its cities and boroughs collect local sales taxes, averaging 1.82% statewide.
