Calculate the original price before tax
Reverse sales tax means finding the original price before tax is added. In the United States sales tax is usually added after the product price. Because of this many people only see the final amount and not the actual price before tax.
This is where reverse sales tax becomes useful. It helps you remove tax from the total amount and find the real cost.
For example if you buy something for 108 dollars and the tax rate is 8 percent the actual price before tax is 100 dollars. The extra 8 dollars is the tax.
This method is also called reverse taxation or backing out sales tax. Many people use a reverse sales tax calculator to make this process fast and accurate.
