Frequently asked questions
Which states have no sales tax?
Five states have no statewide sales tax: Alaska, Delaware, Montana, New Hampshire, and Oregon. However, Alaska allows local governments to levy their own sales taxes (average ~1.7%). New Hampshire taxes restaurant meals and rentals.
Are groceries and food taxed?
It depends on the state. Most states either exempt groceries entirely (California, New York, Texas) or tax them at a reduced rate. Some states like Mississippi and Alabama tax groceries at the full rate. Prepared food (restaurants, fast food) is almost always taxable.
What is the highest combined sales tax in the US?
Louisiana has the highest combined average state + local rate at about 9.55%. Tennessee (~9.55%), Arkansas (~9.44%), and Alabama (~9.24%) are close behind. California has the highest statewide base rate (7.25%), which climbs above 10% in many cities when local taxes are added.
Do I owe sales tax on online purchases?
Yes — following the 2018 South Dakota v. Wayfair Supreme Court ruling, states can require out-of-state online retailers to collect sales tax if they meet certain sales thresholds (usually $100,000/year or 200 transactions). Most major online retailers now collect sales tax in all states that have it.

Average combined sales tax rates by region
Southeast and South: highest rates (7.5–9.5% combined). Northeast: moderate to high (5–8%). West: wide range — California 8–10%+ but Oregon and Montana 0%. Midwest: moderate (5–7%). Always add local rates — the listed state rate is just the floor, not the ceiling.
Sales tax on cars, boats, and big purchases
High-value purchases can involve significant sales tax. A $40,000 car in California with 9% combined rate adds $3,600. Many states cap sales tax on vehicles or use a different rate. Always check the specific rules for your state before a major purchase — some states offer trade-in credits that reduce the taxable amount.
