2026 Real Estate Tax Reform Eases Holding Tax: Why the 'One Prime Property' Trend is Accelerating?

The government has unexpectedly announced the '2026 Real Estate Tax Reform,' confirming its policy to ease the comprehensive real estate holding tax burden for resident owners of a single home. With stricter taxation on multiple-home owners and non-resident high-priced home owners, the tax burden for single-home owners will significantly decrease, signaling a major shift in the real estate market.

Background of the Accelerating 'One Prime Property' Trend

The core of this reform is the drastic holding tax reduction for resident single-home owners coupled with punitive taxes on non-resident high-priced homes. Market experts analyze that to avoid heavy tax burdens, investors will increasingly dispose of multiple properties in suburban areas and consolidate their assets into a single high-priced home in core areas of Seoul and the metropolitan region, intensifying the 'one prime property' phenomenon.

• Tax Burden Polarization: Resident single-home owners can maximize tax benefits, while the cost of maintaining multiple properties will surge.
• Locked-in Supply in Core Areas: It is highly probable that listings in major areas like Gangnam will decrease while asking prices continue to rise.

Freeze in Non-Apartment Market: Concerns are rising that the prolonged slump in the villa and officetel markets, which have recently seen a sharp drop in housing starts, will worsen due to concentrated demand for apartments.

Furthermore, as President Lee Jae-myung pointed out the sluggish housing supply immediately after his overseas trip and ordered follow-up measures, close attention is being paid to potential changes in the government's housing supply policies for core areas.

Frequently Asked Questions (FAQ)

Q. How much will taxes decrease for single-home owners under the 2026 tax reform?

Single-home owners who meet the long-term holding and actual residence requirements are expected to receive up to a 70-80% deduction in comprehensive real estate holding tax compared to previous rates. Specific deduction rates will be finalized through enforcement decrees.

Q. Should multiple-home owners sell their houses immediately?

For multiple-home owners in regulated areas or those holding non-resident high-priced properties, portfolio restructuring is essential as punitive taxes will apply. It may be advantageous to prioritize the sale of non-core assets by utilizing the temporary exclusion period for capital gains tax surcharges.
