FAQ
- I own only one home and the tax comes out as zero. Why?
- A single home owned by one household is exempt when the sale price is 1.2 billion KRW or less, so the tax calculates to zero. Above 1.2 billion KRW, tax applies only to the portion of the gain attributable to the excess.
- Could my actual tax bill be different?
- Yes. This is an estimate based on the standard Korean tax rules and deduction rates in effect since 2023. It does not account for heavy tax rates in regulated zones, inheritance or gift exceptions, or other special conditions, so consult a licensed tax accountant before you file.
- How is the long-term holding special deduction calculated?
- For a single home per household, you get 4% per year for the holding period plus 4% per year for the period you lived there (up to 40% each), for a maximum of 80%. All other property gets 2% per year, up to 30%.
