Frequently Asked Questions
How do I calculate sales tax?
To calculate sales tax, multiply the purchase price by the tax rate as a decimal. For example, a $100 item with 7.25% tax: $100 x 0.0725 = $7.25 in tax, for a total of $107.25.
What is the difference between state and local sales tax?
State sales tax is the base rate charged by the state. Many cities and counties add additional local taxes on top. For example, California has a 7.25% state rate, but your total rate may be 8.5-10.5% depending on your city. The presets in this calculator show state base rates only.
Are all items subject to sales tax?
No, many states exempt certain items from sales tax. Common exemptions include groceries, prescription medications, and clothing (in some states). Some states also have tax-free shopping weekends for back-to-school items.
