VAT, forward and backward
Korean VAT is 10% of the net (supply) amount. To quote a price you add 10%; when you only know the gross total (VAT included), you work backward to the net and the tax.
- Add: VAT = net × 10%, gross = net × 1.1
- Extract: net = gross ÷ 1.1, VAT = gross − net
Simplified taxpayers apply an industry VAT ratio (less tax); exempt goods and zero-rated exports carry no VAT. See the income tax calculator.
