Why does the US use sales tax instead of VAT?

The US has historically used a retail sales tax levied at the point of sale, collected by individual states and localities. VAT is a European-style system that taxes value added at each production stage. The US has never adopted a federal VAT.

Are these rates exact?

The rates shown are the average combined rate (state rate plus average local rate) as published by the Tax Foundation. Actual rates can vary by city or county. Always confirm with your local tax authority for precise compliance.

Which states have no sales tax?

Five states have no state sales tax: Alaska, Delaware, Montana, New Hampshire, and Oregon. Note that some Alaskan localities do impose a local sales tax.

Does this calculator include local sales tax?

Yes. The rates used are average combined rates that include both the state-level rate and the average local (city/county) rate, giving a more realistic estimate of what you will actually pay.

Is sales tax applied to all purchases?

No. Many states exempt certain goods like groceries, prescription drugs, and clothing. This calculator gives a general estimate; your actual tax may differ based on what you are buying.

How do I calculate sales tax manually?

Multiply the pre-tax price by the tax rate (as a decimal). For example, $100 at a 7% rate: $100 × 0.07 = $7.00 tax, for a total of $107.00.
