Tax Reform Follow-Up and Temporary Two-Homeowner Disposal Timelines: Capital Gains Exemption and Tax Strategies

Restructuring of Temporary Two-Homeowner Regulations Under Tax Reform Measures

With follow-up measures to the real estate tax reform taking effect, disposal timelines and capital gains tax exemption conditions for temporary two-homeowner households have emerged as critical market factors. As detailed clauses regarding grace periods and mandatory holding/residence requirements are formalized, taxpayers transitioning between properties must reassess their asset allocation strategies.

The temporary two-homeowner tax exemption is a fundamental mechanism designed to grant households temporarily holding two properties during a relocation process the same tax benefits as single-homeowners (complete exemption up to KRW 1.2 billion in actual transaction price, with long-term holding special deductions up to 80% on the excess). The ongoing enforcement decree amendments focus on clarifying disposal timelines across regulated and non-regulated zones and refining qualification exceptions.

Core Revision Directions and Timeline Calculation Criteria

Under Article 155, Paragraph 1 of the Enforcement Decree of the Income Tax Act, a household owning one residential property must acquire a second property at least one year after acquiring the first, and subsequently dispose of the prior property within a specified grace period to qualify for the exemption.

• Disposal Grace Period: The baseline requirement remains disposal within three years from the acquisition date of the new property, accompanied by refined criteria covering completion delays in urban redevelopment and reconstruction projects.
• Holding Period Calculation: The timeline commences on the earlier of the final balance payment date or the registration receipt date of the new property, with revised administrative guidelines to prevent liabilities arising from transaction settlement gaps.
• Pre-sale and Reconstruction Rights Exceptions: Verification standards have been tightened for alternative housing schemes, which require the entire household to move into the new home within three years of construction completion and reside continuously for at least one year.

Interconnected Impacts on Acquisition Tax and Comprehensive Real Estate Holding Tax

Temporary two-homeowner exemptions extend beyond capital gains tax, directly governing acquisition tax surcharges and comprehensive real estate holding tax thresholds.

1. Acquisition Tax Surcharge Exemption

To qualify for the standard single-homeowner acquisition tax rate (1% to 3%) on a newly purchased property, the prior residence must be disposed of within the statutory timeline. Failure to meet this requirement results in retroactive imposition of multi-homeowner surcharge rates (up to 8% or 12%) along with penalty taxes, underscoring the importance of synchronizing transaction closings.

2. Retention of Comprehensive Real Estate Holding Tax Status

Taxpayers filing for the temporary two-homeowner exemption as of the June 1 taxation assessment date preserve the KRW 1.2 billion base deduction alongside elderly and long-term holding tax credits of up to 80%. However, if the prior residence is not sold within the designated period, retroactive taxes and interest penalties are applied.

Execution Strategies and Key Checkpoints for Property Owners

In periods of constrained transaction liquidity, delaying sales risks forced price cuts near statutory deadlines. Taxpayers should observe the following verification protocol:

• Acquisition Gap Verification: Ensure that the new property was acquired strictly after a full 1-year gap from the acquisition date of the existing property to preserve exemption eligibility.
• Controlled Sales Timeline: List the existing property at competitive market pricing at least six months prior to the statutory deadline, structuring payment terms to secure completion within the compliance window.
• Residence Requirements for Deductions: If the original property was acquired while designated under regulated zones, confirm completion of the mandatory two-year residence requirement to fully realize maximum long-term holding deductions.
