Why use Sales Tax Calculator?

Sales tax in the United States is a patchwork of state, county, city, and special-district rates. This calculator gives you a practical combined rate for Texas, Florida, California, and New York, either a state average or a named city when you need more precision, and shows the state and local portions of that rate separately so you can see where the number comes from. Forward mode answers: "What do I pay on a $249 item?" Reverse mode answers: "How much of this $108 total is tax?" Both use the same combined rate, round to the nearest cent, and update the moment you change the state, city, mode, or amount, so you can compare scenarios quickly. Every state page also shows a fixed $100 example calculated at that state's average rate for a quick sanity check. Check the disclaimer on each page and confirm rates with your state comptroller before relying on them for compliance, since local district and special taxes can push the real rate above or below the figure shown here.

Choose state and city
Select your state from the dropdown. If the state has city-level data, a city dropdown appears; pick one for a tighter combined rate or leave it on "State average".

Forward mode adds tax to a shelf price. Reverse mode splits a tax-included total back into its pre-tax price and tax portion.
3
Enter the amount
Type the dollar amount into the Price or Total field, depending on the mode you picked. Results update instantly as you type.
4
Read the breakdown
Review the combined rate shown as state plus local percentage, then check the pre-tax price, sales tax, and total cards, plus the $100 example for your state.

Frequently asked questions

Are these rates exact?

They are combined state plus local averages or city snapshots as of the last update date shown on the page. District, county, and special district taxes can differ block by block.

What is reverse mode?

You enter the total price including tax. The tool divides by (1 plus the combined rate) to find the pre-tax subtotal, then the tax portion is the difference between the total and that subtotal.

Why is NYC higher than Albany?

New York City adds local sales tax on top of the state rate. Pick "New York City" in the city dropdown for the NYC combined rate instead of the statewide average.

Is this for use tax?

This calculator handles simple sales tax math only. Use tax and nexus rules for remote sellers are outside its scope.

What happens if I do not pick a city?

The calculator falls back to the state average local rate added to the state rate, so you still get a usable combined rate even without picking a specific metro.
