How to calculate sales tax
Use the combined rate where the order is delivered.
- Sales tax
price × rate$100 × 8.25% = $8.25 - Total with tax
price × (1 + rate)$100 × 1.0825 = $108.25 - Price before tax
total ÷ (1 + rate)$108.25 ÷ 1.0825 = $100.00
Worked example: a $100 sale in Houston, TX
| State of TexasState | 6.25% | $6.25 |
|---|---|---|
| HoustonCity | 1% | $1.00 |
| Houston MTASpecial district | 1% | $1.00 |
| Sales tax | 8.25% | $8.25 |
The customer pays $108.25. Some products are only partly taxed: Texas taxes software as a service on 80% of the price, so $100 of SaaS in Houston carries $6.60.

How do I calculate sales tax?
Multiply the taxable part of the price by the combined rate where the order is delivered: the state rate plus any county, city and special-district rates. A $100 sale at 8.25% carries $8.25 of tax, for a total of $108.25.
How do I work out the price before tax from a total?
Divide the total by one plus the rate. A $108.25 total at 8.25% is $108.25 ÷ 1.0825 = $100.00 before tax, so the tax was $8.25. The add-or-remove tool above does this for any rate.
Why does the calculator need a street address?
Special districts, such as transit and emergency-services districts, don’t follow ZIP codes or city limits, so two addresses in the same ZIP can have different rates. The Zamp API calculates for the exact address, the same way it does for Zamp customers at checkout.
Can I look up sales tax by ZIP code?
A ZIP code is a good first guess, but many ZIP codes cross city and district lines and so contain more than one rate. Enter the street address for the exact rate.
Is the rate the same for every product?
No. States exempt or partly tax some products, such as groceries, clothing, prescription drugs and software. Choose what you’re selling and the calculator applies that state’s rules.
Do I charge tax on shipping?
It depends on the state. Add a shipping amount and the calculator shows whether shipping is taxed at that address, and how much.
Which states have no sales tax?
Alaska, Delaware, Montana, New Hampshire and Oregon have no statewide sales tax. Many Alaska towns and boroughs, and a few Montana resort areas, still charge their own.
How often do sales tax rates change?
Local rates change every quarter somewhere. Of the 4,473 cities Zamp checks, 1024 have a different combined rate today than in July 2023. Zamp re-checks every rate monthly.
Do I have to charge sales tax to customers in other states?
Only in states where you have nexus. Besides a physical presence, most states set an economic threshold, usually $100,000 in sales into the state a year; the table above lists each state’s.
