Couple joint ownership tax calculator

This English page follows the Korean couple joint-ownership tax calculator for acquisition tax, property tax, comprehensive real-estate tax, capital gains tax, gift tax, and title-change effects.

Comprehensive real-estate tax

The fair market value ratio is 60 percent in the Korean source. Sole one-house ownership uses the one-house comprehensive-real-estate-tax deduction of KRW 1.2 billion and can apply age and holding credits up to 80 percent.

Joint ownership usually gives each spouse a KRW 900 million deduction, or KRW 1.8 billion combined, but ordinary joint owners do not automatically receive the one-house age and holding credits. Since 2023, the joint one-house special election can use the KRW 1.2 billion deduction and credits where it is more favorable.

Capital gains and gift transfer

Capital gains tax can benefit from splitting progressive 6 to 45 percent brackets and the KRW 2.5 million basic deduction for each spouse. However, one-house exemption up to KRW 1.2 billion sale price is not doubled just because title is split.

The spousal gift deduction is KRW 600 million over 10 years. Gift acquisition tax is typically 3.5 percent, but regulated-area housing of KRW 300 million or more can trigger a 12 percent acquisition-tax branch, so a title change is not free.

When joint title helps

Joint title is most useful when comprehensive-real-estate-tax deduction splitting or capital-gain bracket splitting outweighs gift and acquisition costs. It can be worse when one-house credits are lost or a regulated-area gift triggers heavy acquisition tax.

The English calculator calls the same calculateComparison function and DEFAULT_INPUT as the Korean page. It is a parity calculator for the household tax profile, not a generic 50 percent split display.
