Real Estate Tax Reform: Shift to Value-Based Assessment and Its Market Impact
The government is pushing to shift the real estate holding tax criteria from the number of houses to total property value, easing the tax burden on multiple-home owners.

The government is strongly considering a shift in the comprehensive real estate holding tax criteria from the current 'number of houses' to 'total property value'. This move aims to resolve equity issues where tax burdens varied significantly based on the number of homes owned despite having the same asset value. A detailed tax reform plan is expected to be announced by the end of July.
Key Background and Market Impact of the Tax Reform
Transitioning to Value-Based Assessment
Under the current system, multiple-home owners face much higher punitive tax rates than single-home owners. This has led to an inversion where someone owning several low-priced regional homes pays more tax than someone owning a single luxury apartment in Seoul. If reformed to a value-based system, the tax burden on multiple-home owners will ease, potentially cooling down the 'one smart house' phenomenon (preference for high-end apartments in core Seoul areas) driven by tax avoidance.
Restructuring Tax Benefits Around Actual Residence
Furthermore, tax deductions for single-home owners are expected to be restructured based on 'actual residence periods' rather than simple ownership duration. This reflects the government's intention to curb speculative demand by reducing benefits for ultra-high-priced homes where the owner does not actually reside.
