Method and system for providing tax funds{METHOD AND SYSTEM FOR TAX REFUND}

The present invention relates to a method and system for providing tax funds.

Tax Refund is a tax exemption (10%) and individual consumption tax (5-20%) included in the purchase price, as well as exemption from customs duties when tourists leave the country with their purchased items while traveling abroad. It is a tax-free system. The targets for tax funds are permanent residents and overseas Koreans who purchase at least 30,000 won, take out purchased goods overseas within 3 months, and stay in Korea for less than 3 months and stay abroad for 2 years or more.

Major companies that provide tax funds include Global Tex Free, Global Blue, KTIS, Cube Refund, and Easy Tex Free. You can receive tax rebate benefits when purchasing goods at affiliated stores of these businesses, and there are signs such as'TAX FREE' and'TAX REFUND' in the store, so tourists can easily recognize the tax rebate store.

The general procedure for providing tax funds is as follows. First, after the tax rebate purchases goods at a duty free shop, a refund slip and receipt are received for each purchase. Tax return recipients have customs declaration and confirmation of purchased items upon departure. In other words, the target of tax repayment goes through the process of verifying the identity, comparing purchased goods with receipts, and submitting a refund slip. Upon completion of the customs declaration and purchase process, tax refund recipients submit a refund slip to the airport refund counter and receive tax refunds after 2-3 weeks.

According to the VAT refund procedure, the tax rebate recipient is required to receive and store the refund slip every time he/she purchases an item, and upon departure, he/she must check with the customs office and submit it to the refund window. The entire process from submitting a refund window was very cumbersome. In addition, there is a inconvenience in that a refund slip must be reissued if lost or damaged. Therefore, there have been frequent cases where refunds are not given or refunds become impossible due to such inconvenience.
