How It Works

Formula

Sales Tax = Purchase Amount × Tax Rate
Total = Purchase Amount + Sales Tax

Local Taxes

Many cities and counties add local sales taxes on top of the state rate. The combined rate can be significantly higher than the state base rate. For example, in some California cities, the combined rate exceeds 10%.

Frequently Asked Questions

Is sales tax deductible?

If you itemize, you can deduct either state income tax OR sales tax (not both) as part of SALT, which is capped at $10,000. This benefits residents of states without income tax.

What items are tax-exempt?

It varies by state. Common exemptions include groceries, prescription drugs, and clothing (in some states). Check your state's rules.

What about online purchases?

Since 2018 (South Dakota v. Wayfair), states can require online retailers to collect sales tax even without physical presence. Most major retailers now collect tax for all states.

How do I find my exact local rate?

Check your state's department of revenue website or use their rate lookup tool. Rates can vary by exact address due to different local taxing jurisdictions.

What is use tax?

Use tax applies when you buy something without paying sales tax (e.g., from out of state) but use it in your state. You're supposed to self-report and pay the tax.

Are there sales tax holidays?

Many states have annual sales tax holidays (often for back-to-school) when certain items are tax-free. Check your state for dates and eligible items.
