Foreign tax refund refers to the process of applying for a tax refund from a tax refund company while shopping with a tax refund voucher. The tax refund voucher usually includes information about the business and purchased goods, as well as the amount of the tax refund. Tax refunds are generally available in cash or directly deposited into a bank card.

When shopping abroad, you may encounter some businesses offering tax refund services.
