VAT calculator: supply price and total
Add VAT to a supply price, or split a VAT-inclusive total into the supply price and the VAT.
How VAT is calculated
VAT is the supply price multiplied by the tax rate. The standard rate in Korea is 10%. To get the supply price from a total, divide the total by 1.1.
Rounding
VAT is rounded to the whole won. Real receipts can differ by 1 won depending on how they are issued.
When the rules differ
Tax-exempt goods, zero-rated sales and simplified taxpayers can be treated differently. Check the National Tax Service guidance for your case.
