<p>The Korean government has been striving to enhance transparency in all commercial transactions with the objective of achieving equity within the context of taxation. One of the keys to accomplishing such an objective is the use of an income tax deduction scheme calculated using receipts from credit card and cash transactions. Under this scheme, if a taxpayer made a payment via credit card and/or cash, that individual would be entitled to a tax deduction of a prescribed percentage of the purchased amount from their taxable income base. This scheme aims to encourage the taxpayers to actively use credit cards and cash receipts, which allow the disclosure of their transaction history to a third party, in the course of their economic activities. The ultimate goal of this scheme is to enhance transparency of income derived by businesses which provide a product or service directly to the end users</p>
