Abstract: A method begins when a merchant sells to a retail consumer. The consumer then pays the merchant by credit card or debit card. The terminal of the merchant collects the sales data and transmits the sales data to a processor along with the sales revenue. The processor determines the geographic location of the merchant or the customer and the type of goods and services purchased, and then refers to an electronic table of tax rates by taxing authority. The processor then calculates the appropriate sales taxes and its commission upon a computer system. The processor then divides the sales taxes and commission from the sales revenue from immediate deposit to a collecting government agency and the merchant respectively. The method collects sales data upon the terminal or keypad of the merchant at the point of sale.
