FAQ
What is the VAT rate in Korea?
Korea applies a flat 10% VAT (부가가치세) on most goods and services. Some items like unprocessed food, medical services, and education are VAT-exempt.
How do I calculate supply amount from total?
Divide the total (VAT-inclusive) amount by 1.1. For example, if the total is 110,000 won, the supply amount is 100,000 won and VAT is 10,000 won.
Is the VAT always exactly 10%?
Yes, Korea has a single VAT rate of 10%. There is no reduced rate. However, some transactions are zero-rated or exempt.
Can I use this for tax filing?
This tool provides accurate calculations based on the 10% rate, but for official tax filing, please use the National Tax Service (NTS/홈택스) system.
How does bulk calculation work?
Enter multiple supply amounts, one per line. The tool calculates VAT and total for each line and shows a grand total at the bottom.
