How do I find my local sales tax rate?

Sales tax rates vary by state, county, and city. You can find your local rate on your state's department of revenue website or by searching 'sales tax rate [your city]'. The US average combined rate is about 6.5-7.5%, but ranges from 0% to over 10%.

What is the reverse sales tax calculation?

If you know the total price including tax and the tax rate, you can find the pre-tax price by dividing the total by (1 + tax rate). For example, a $107.50 total at 7.5% tax means the pre-tax price was $107.50 / 1.075 = $100.

Does this calculator handle VAT?

The math is the same for VAT (Value Added Tax) calculations. Enter the VAT rate as the tax percentage, and the calculator works identically. European VAT rates typically range from 17% to 27%.

Why is my calculated tax amount different from my receipt?

Small differences can occur due to rounding rules. Some jurisdictions require rounding tax to the nearest cent per item, while others round the total tax. Our calculator uses the most common method (rounding the final tax amount). Differences are usually just a penny or two.

Can I use this for business expense reporting?

Yes. The reverse calculation is specifically designed for this — enter the total from your receipt and the applicable tax rate, and you'll get the pre-tax amount that most expense reporting systems require.
