About this tool
Korea's value-added tax (VAT, ๋ถ๊ฐ๊ฐ์น์ธ) is a flat 10% on most goods and services. This calculator works in both directions. From the supply price (๊ณต๊ธ๊ฐ์ก, the price before tax) it adds 10% to give you the VAT and the total. From the total price (ํฉ๊ณ๊ธ์ก, tax included) it divides by 1.1 to find the supply price, and the remainder is the VAT. For example, a supply price of 1,000,000 won gives 100,000 won of VAT and a total of 1,100,000 won. In reverse, a total of 550,000 won means a supply price of 500,000 won and 50,000 won of VAT. Amounts are rounded to the nearest won, so a tax invoice issued by your accounting system may differ by a won or so. Some items such as unprocessed food, books and medical services are VAT-exempt or zero-rated, and simplified taxpayers use different rates, so check your own case. The results are estimates for reference and do not replace advice from a tax professional.
