Meet Sales Tax Calculator — the quickest way to find the sales tax rate for any United States location and work out the tax on any amount, right inside your browser. Type a place, type a price, get your number.

🧩 Sales tax in the US is a maze. Thousands of jurisdictions stack state, county, city, and special district rates on top of each other, and the numbers change throughout the year. Whether you sell online, run a register, or keep the books for clients, the wrong rate means overcharging customers or coming up short at filing time. This tool does the maths for you and shows exactly how the rate breaks down.

🔁 It also works backward. Got a receipt total and need the pre-tax price? The built-in reverse sales tax calculator strips it out, so you see the base amount and the charge apart in one step.

Here is how it works:

1. Open the extension from your toolbar.

2. Enter a US address, a zip code, or pick a state.
