Sales Tax Calculator

About

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 math 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.
3. See the combined rate, then type any price to add or remove it.

Two modes, one tool:
➤ Forward — enter a price and it acts as an add tax calculator, showing the total
➤ Reverse — enter a total and it shows the pre-tax price and the amount apart
➤ Lookup — get an estimated rate as a sales tax calculator by zip code or by state
➤ Breakdown — your state rate and an estimated local rate, combined into one number

🚗 Buying a car? It works as a quick car sales tax calculator too: type the price and your rate to estimate the tax before you sign. For a vehicle, confirm your state's specific rules — rates can differ.

🔍 Most rate tools hand you a single number and leave you guessing. Here you see how it is built — the state portion plus an estimated local add-on — so the total makes sense, and you can adjust the rate when you know your exact one. That bit of transparency is what turns a quick check into something you can actually trust.

Who it is for:
1️⃣ Online sellers checking rates across states and carts
2️⃣ Accountants and bookkeepers running a fast sales tax estimator across clients
3️⃣ Small business owners using it as a retail tax calculator or store tax calculator at the counter
4️⃣ Shoppers who just want a plus tax calculator before they buy

Everyday uses:
- A quick check as an online sales tax calculator before sending an invoice
- A purchase tax calculator for any item, from a grocery run to a restaurant tax calculator total
- A sales tax percentage calculator when you only have the percent and the price
- A deduction helper when you gather numbers at tax time

🗺️ Built for every state. People reach for it as a state sales tax calculator in Texas, California, Missouri, New York, New Jersey, Florida, Ohio, Washington, Illinois, and the rest, because the combined local rate is included, not just the statewide number. As more cities and counties adjust their numbers each year, having a current figure a click away saves a surprising amount of back-and-forth.

⚠️ A note on accuracy: results are estimates based on the location you enter, and a precise figure can depend on the exact rooftop address within a zip. Confirm against your official state guidance before filing — this is a fast rate finder, not legal or tax advice.

Why people keep it pinned:
🔹 No sign-up, no account, nothing to configure
🔹 A lightweight everyday tool, not a heavy platform
🔹 No data sent anywhere — every lookup runs locally
🔹 Instant — open, type, done
