How to Convert Oven Recipes to Air Fryer
Sales tax is a percentage added to the purchase price of goods and services. This calculator works in three modes to solve any sales tax problem.
The basic rule:
- Add Tax: Total = Price × (1 + Tax Rate ÷ 100)
- Remove Tax: Pre-tax Price = Total Price ÷ (1 + Tax Rate ÷ 100)
- Find Rate: Tax Rate = (Tax Amount ÷ Pre-tax Price) × 100
- US sales tax varies by state, county, and city — rates range from 0% to 10%+
Five states have no state sales tax: Alaska, Delaware, Montana, New Hampshire, and Oregon. However, some Alaska localities charge local sales tax. Always check combined state + local rates for accurate calculations.

Frequently Asked Questions
How do I calculate sales tax?
Multiply the price by the tax rate as a decimal. For example, $50 at 8% tax: $50 × 0.08 = $4.00 tax. The total is $50 + $4 = $54.00. This calculator does this automatically in 'Add Tax' mode.
How do I find the pre-tax price from a total?
Divide the total price by (1 + tax rate as a decimal). For example, if you paid $54 with 8% tax: $54 ÷ 1.08 = $50.00 pre-tax price. Use 'Remove Tax' mode for this calculation.
Which states have no sales tax?
Five states have no state-level sales tax: Alaska, Delaware, Montana, New Hampshire, and Oregon. However, Alaska allows local jurisdictions to charge sales tax, so some Alaska cities do have a local sales tax.
Which state has the highest sales tax?
California has the highest state sales tax rate at 7.25%. However, when combined with local taxes, Tennessee and Louisiana often have the highest total rates, with some areas exceeding 10%.
Is sales tax included in the listed price?
In the United States, sales tax is almost always added at checkout and not included in the displayed price. In most other countries, VAT (value-added tax) is included in the listed price.
Do I pay sales tax on online purchases?
Yes, in most cases. Since the 2018 Supreme Court ruling in South Dakota v. Wayfair, states can require online retailers to collect sales tax even without a physical presence in the state. Most major online retailers now collect sales tax in all applicable states.
