Sales Tax Calculator

Divide the total by (1 + rate), don't subtract the percentage. A $108.25 total at 8.25% is 108.25 ÷ 1.0825 = $100.00 pre-tax. Subtracting 8.25% of the total instead gives $99.32 — wrong, because the tax was charged on the smaller pre-tax number, not on the total.

Local stacking. Most states allow county, city, and special-district taxes on top of the base: Texas is 6.25% statewide but commonly 8.25% at a register; parts of Louisiana and Alabama exceed 10% combined. The dropdown gives the state floor — a recent receipt from your area gives the true combined rate.

Delaware, Montana, New Hampshire, and Oregon have none at any level. Alaska has no state rate but permits local sales taxes, so some Alaskan cities do charge. This is why big-ticket buyers near borders sometimes cross state lines — though technically use tax often applies back home.

No — most states exempt or reduce tax on groceries, many exempt prescription drugs, some exempt clothing below a threshold, and digital goods rules are a patchwork. This calculator does the arithmetic for whatever rate applies; what's taxable in your state and category is a separate (and messier) question.
