Temporary two-house capital gains tax calculator

This English page follows the Korean temporary two-house capital-gains-tax calculator for a household that buys a replacement home before selling the old home.

Three core requirements

The legal basis is Income Tax Act Enforcement Decree Article 155(1). The new house must be acquired after at least 1 year from old house acquisition, and the old house must be sold within 3 years from new house acquisition.

The old house must independently meet the one-house exemption requirements: at least 2 years of holding, and if it was acquired in a regulated area on or after 2017-08-03, at least 2 years of residence. Non-regulated houses and pre-2017-08-03 acquisitions generally do not need residence for this branch.

2023 simplification and deadline risk

The 2023-01-12 amendment unified the disposal deadline to 3 years. Before the amendment, regulated-area combinations could have 1-year or 2-year deadlines and move-in requirements; under the 2026 rule set used here, the old house generally must be sold within 3 years of new house acquisition regardless of region combination.

Missing the deadline by even a short period can remove the exemption and turn the old house into an ordinary taxable two-house sale. The calculator reports the disposal deadline and days left from the entered sale date, so the balance date can be planned before the tax deadline rather than near it.

High-value and ordinary taxation

If the sale price exceeds KRW 1.2 billion, exemption applies only up to the high-value threshold and the excess portion is taxed. The taxable capital gain = total capital gain x (sale price - KRW 1.2 billion) / sale price, then the one-house long-term holding and residence deduction can reduce tax.

If exemption fails, ordinary capital gains tax applies. Short-term rates are 70 percent under 1 year and 60 percent under 2 years. A two-house surcharge is 20 percentage points but suspension runs from 2022-05-10 to 2026-05-09 in the Korean constants, so actual surcharge exposure still depends on sale date and regulated-area status.
