How do I find the pre-tax price from a total? ▼
Divide the total by (1 + tax rate). Example: $97.41 ÷ 1.0825 = $89.99 pre-tax. Use "Remove Tax" mode above.

Does sales tax apply to groceries? ▼
It depends on the state. Most states exempt unprepared food from sales tax. Prepared food (restaurants, hot food) is almost always taxed.

The state base rates shown are state-level only. Your actual rate includes local (city/county) taxes, which can add 0–5%. Check your receipt or your city's tax authority for the exact combined rate.
