US Sales Tax Calculator
Forward or reverse sales tax for all 50 states and DC — statewide rates, your local add-on, dated data.
Privacy Notice: This tool runs entirely in your browser. Nothing you generate or enter is sent to any server or stored anywhere.
Estimates only — this is not tax advice. Sales tax depends on the exact address of the sale (state, county, city, special districts), and rates change. Confirm the final rate with the relevant state Department of Revenue before filing or invoicing. Everything here runs in your browser — nothing you type is uploaded.
Examples
Forward: $100 in Texas
amount $100 · Texas 6.25% · no local add-ontax $6.25 · total $106.25total = $100.00 × (1 + 6.25%) — the state's maximum combined rate is 8.25% with 2% local.
Forward with local add-on: $59.99 in Illinois
amount $59.99 · Illinois 6.25% + 2% localtax $4.95 · total $64.94The local field stacks on top of the statewide rate: 8.25% applied, formula shown under the result.
Reverse: splitting a $106.25 receipt
total $106.25 · Texas 6.25%pre-tax $100.00 · tax $6.25pre-tax = $106.25 ÷ (1 + 6.25%) — the same split bookkeepers book to price and sales-tax-payable accounts.
About this tool
The US Sales Tax Calculator answers the two questions every shopper and small business asks: how much will this cost after tax, and how much of a total was tax. Pick any of the 50 states or the District of Columbia and the tool loads that jurisdiction's statewide rate from a dated table — effective July 1, 2026 and re-verified against the Tax Foundation's midyear compilation. Forward mode multiplies your before-tax amount by the rate and reports the tax and the total; reverse mode divides an after-tax total by one plus the rate to recover the pre-tax price and the tax hiding inside it, which is exactly the split bookkeepers need when a receipt shows only one number.
State sentences people actually search for work the same way. Looking for a Texas sales tax calculator? Select Texas and $100 becomes $6.25 tax and a $106.25 total at the 6.25% statewide rate — add 2% for Dallas or Houston's local tax and the total lands at $108.25. A California sales tax calculation uses 7.25%, the highest statewide rate in the country, and that figure already includes California's mandatory 1.25% local add-on. A New York sales tax calculator shows just 4% statewide because New York City and counties add up to 4.54% on average — that gap is why the optional local add-on field exists.
The local add-on field is deliberate. City, county and special-district rates change constantly and vary street by street, so the tool refuses to guess them: it applies the statewide rate plus whatever local percentage you enter, capped sensibly at 15%, and says so in the formula line under the result. Colorado is the clearest example of why — 2.9% statewide, the lowest non-zero rate in the nation, with local taxes averaging 4.99% that frequently exceed the state's own share. Louisiana sits at the other extreme with the highest average combined rate, 10.13%.
Five states levy no statewide sales tax at all: Alaska, Delaware, Montana, New Hampshire and Oregon. The calculator does not paper over them. Delaware, Montana, New Hampshire and Oregon report a zero tax and a notice that the sticker price is the final price; Alaska adds the honest caveat that many of its localities levy their own taxes, averaging 1.82%. Every result carries its arithmetic — amount × (1 + rate) or total ÷ (1 + rate) — so you can audit the math at a glance, and the nationwide population-weighted average combined rate for context sits at 7.53%.
What this tool does not do
- The calculator applies statewide rates plus a single user-entered local percentage; it does not hold per-city or per-county rate tables.
- Special treatment is out of scope: exempt groceries, clothing holidays, and reduced-rate categories are not modeled.
- Hawaii, New Mexico and South Dakota tax many business-to-business services (gross-receipts-style bases), so their rates overstate a typical consumer's burden.
- Amounts are capped just under $100 million so the cent-exact arithmetic stays exact; results round half-up to the cent.
- This is an estimation aid, not tax advice — confirm final rates with the state Department of Revenue.
How to use this tool
Choose the direction
Pick Forward — add tax to work from a price, or Reverse — find pre-tax to split an after-tax total.
Enter the amount
Type the before-tax amount or after-tax total in dollars; commas and a dollar sign are fine.
Select the state
Choose one of the 50 states or DC from the dropdown — the statewide rate loads from the dated table.
Add local tax if you know it
Optionally enter your city or county add-on as a percent (0–15). Leave it blank to use the statewide rate only.
Read the result
Press Calculate: the tax amount, total, applied rate and the exact formula appear; zero-tax states show an honest notice instead.
Use cases
Pricing and invoicing
Quote a customer the final, tax-inclusive number by stacking your state's rate with your city's add-on before the invoice goes out.
Bookkeeping from receipts
Reverse an after-tax total into pre-tax price and sales tax so expense entries split correctly across accounts.
Comparing state costs
Check the 51-row table before a large purchase — 0% in Oregon or Delaware against 10.13% average combined in Louisiana is a real price difference on a car or appliance.

Common mistakes
Mistake:Assuming the statewide rate is the whole story.
Fix:Most states let cities and counties add their own tax. Use the local add-on field with your jurisdiction's rate; the tool's average-local column is context, not your rate.
Mistake:Subtracting the rate from the total to reverse it.
Fix:$106.25 minus 6.25% is $99.59, which is wrong. The correct split divides by (1 + rate): $106.25 ÷ 1.0625 = $100.00. Use the Reverse tab.
Mistake:Trusting a remembered rate from an old checkout.
Fix:Rates change — Louisiana raised its statewide rate in 2025, and local rates shift every quarter. The table here is dated; so is any rate you remember.
Frequently asked questions
How do I calculate sales tax on $100 in Texas?
Multiply the amount by the rate: Texas charges 6.25% statewide, so $100 × 1.0625 = $106.25 — $6.25 of tax. Cities and counties may add up to 2% more (8.25% total, e.g. in Dallas or Houston), which would make the total $108.25. Enter the amount, pick Texas, and add your local percentage in the calculator's local add-on field to get the exact split.
What states have no sales tax?
Five states levy no statewide sales tax: Alaska, Delaware, Montana, New Hampshire and Oregon. Delaware, Montana, New Hampshire and Oregon have no local sales taxes either, so the sticker price is the final price. Alaska is the exception — many of its localities levy their own sales taxes, averaging 1.82% statewide, so add your local rate in the calculator for an Alaska total.
How do I calculate the pre-tax amount from a total?
Divide the total by one plus the rate, not by the rate: pre-tax = total ÷ (1 + rate). For a $106.25 receipt in Texas, $106.25 ÷ 1.0625 = $100.00 pre-tax and $6.25 tax. Subtracting 6.25% from the total instead gives $99.59, which understates the pre-tax price. The calculator's Reverse tab does this division for you and shows the tax separately.
Why does my local rate differ from the statewide rate?
Because most states let cities, counties and special districts stack their own sales tax on top. Colorado charges 2.9% statewide but local taxes average 4.99%; New York's 4% statewide becomes 8.54% average combined once city and county taxes join. This calculator applies the statewide rate plus the local percentage you enter, since local rates vary address by address and change too often to hard-code.
When was this rate table last updated?
The statewide rates are effective 2026-07-01 and the table was last verified against the source on 2026-11-09. The data comes from Tax Foundation — State and Local Sales Tax Rates, Midyear 2026 (Sales Tax Clearinghouse; state revenue department websites). Both dates shown in the calculator come from the same table the math uses, so the page cannot drift out of sync with its own rates.
Is this tax advice?
No. The calculator is an estimation aid: it applies published rates to the amounts you enter and is not a substitute for professional advice. Which rate legally applies depends on the exact location and nature of the sale — nexus rules, product exemptions and district boundaries all matter. Confirm the final rate and your filing obligations with the relevant state Department of Revenue or a tax professional.
