Calculating the Correct Amount of Sales Tax

A sales tax calculator is a useful tool for businesses to quickly determine the total sales tax owed on a purchase. Chicago sales tax rates apply to taxable items. The rate is at 10.25%, including state, county, city, and special tax components. Retailers must accurately calculate and collect sales tax to stay compliant with local and state tax regulations.

To manually calculate the sales tax on a purchase, use the following formula:

Sales Tax = Total Sale Amount × Sales Tax Rate

Example: Let’s say a retailer sells a product for $500 in Chicago. The total sales tax rate is 10.25% (or 0.1025 in decimal form).

Step 1: Calculate the sales tax

Sales tax: 500 × 0.1025 = 51.25

So, the sales tax on a $500 purchase is $51.25.

Step 2: Calculate the total amount the customer pays

Total price: 500 + 51.25 = 551.25

The customer will pay $551.25 in total, including sales tax.

Retailers should ensure they apply the correct rate to every sale and report collected taxes to the appropriate tax authorities.
