* Reference calculation. The multi-home surtax is simplified based on regulated-area/basic-rate application (2 homes +20%p, 3+ homes +30%p, special deduction excluded). Single-home exemption, pre-sale right special provisions, surtax exclusions (low-price regional/inherited homes), and the tiered 80% long-term deduction are not reflected — verify with a tax professional before filing.
The capital gains tax calculator applies the long-term holding special deduction to real estate gains, then applies the relevant rate to compute capital gains tax and local income tax. It reflects the multiple-home surcharge (resumed May 9, 2026) and whether the property is in a regulated area.
Long-term holding special deduction
A single-house, single-household owner can deduct up to 80% based on holding and residence period, but this deduction doesn't apply if the multiple-home surcharge applies.
Multiple-home surcharge rate
In a regulated area, a second house adds 20 percentage points to the base rate, and a third or more adds 30 points. The moratorium ended and the surcharge resumed as of May 9, 2026.
Frequently Asked Questions
What are the requirements for the single-house, single-household exemption?
Holding the property for 2+ years (including 2 years of residence if it was in a regulated area at acquisition) with a sale price of 1.2 billion won or less qualifies for tax exemption.
Why is the rate higher for short-term sales (within 1–2 years)?
To discourage speculative short-term trading, holding under 1 year is taxed at up to 70%, and 1–2 years at 60%.
Where can I check if an area is regulated?
You can check through Ministry of Land, Infrastructure and Transport and local government announcements; since designations change over time, verify as of the sale date.
Is capital gains tax charged on presale rights (bunyangkwon)?
Yes — a presale right is treated as a right to acquire real estate and is subject to capital gains tax, with a separately higher rate depending on the holding period.
How is the acquisition cost calculated for inherited or gifted property?
The inheritance/gift value reported at the time (fair market value or standard assessed value) is treated as the acquisition cost when calculating the gain.
By when must capital gains tax be filed and paid?
Within 2 months of the last day of the month the transfer occurred, as a preliminary filing — late filing incurs penalties.
Can a temporary two-house owner still get the exemption?
If the existing house is sold within a certain period (typically 3 years) after acquiring a new one, the single-house exemption special case can still apply.
