Sales tax receipts are documents that provide evidence of payment for goods or services purchased, and which also show the amount of sales tax paid. Sales tax is a form of consumption tax charged on goods and services sold in a particular jurisdiction. The money collected from sales tax goes to the government to help fund various public programs and services. When an individual makes a purchase that incurs sales tax, they are usually given a receipt showing the amount of tax paid along with the total cost of the item or service purchased. Sales tax receipts may also be used for business expense deductions on income tax returns.
