How to Calculate Sales Tax
Enter your purchase amount, select your state, and add your local tax rate. The combined rate is the state rate plus local rate.
Formula
Tax Amount = Pre-Tax Price Γ Combined Rate
Total Price = Pre-Tax Price + Tax Amount
Pre-Tax Price (from inclusive) = Total / (1 + Rate)
Total Price = Pre-Tax Price + Tax Amount
Pre-Tax Price (from inclusive) = Total / (1 + Rate)
Example
$200 purchase in Dallas, TX (8.25% combined):
Tax = $200 Γ 8.25% = $16.50
Total = $200 + $16.50 = $216.50
Tax = $200 Γ 8.25% = $16.50
Total = $200 + $16.50 = $216.50

Frequently Asked Questions
Which US states have no sales tax?
Five states have no statewide sales tax: Alaska, Delaware, Montana, New Hampshire, and Oregon. However, Alaska and Montana allow local municipalities to collect their own sales taxes.
How is sales tax calculated?
Sales tax = Purchase Amount Γ (State Rate + Local Rate). For example, $100 in Dallas, TX (8.25% combined) = $100 Γ 0.0825 = $8.25 tax, totaling $108.25.
Is sales tax the same across a state?
No. Most states allow cities and counties to add local sales taxes on top of the state rate. The combined rate varies by location within the same state.
What items are exempt from sales tax?
Many states exempt groceries, prescription medications, and clothing under a certain value. Exemptions vary widely by state. Always check your state's specific rules.
Do I owe sales tax on online purchases?
Yes. Following the 2018 Supreme Court ruling in South Dakota v. Wayfair, online retailers must collect sales tax in states where they have economic nexus, typically $100,000 in sales or 200 transactions.
