[Deep Dive] 2026 Real-Residence Tax Reform Controversy: Core Issues and Legislative Outlook

A Paradigm Shift in Real Estate Taxation: Why the Controversy?

The real-residence tax reform plan included in the '2026 Tax Reform Plan' announced by the Ministry of Economy and Finance on August 3, 2026, is causing significant ripples in the market. By shifting the taxation standard from the 'number of houses and holding period' to 'house value and actual residence period', the reform has sparked controversy as the tax burden varies significantly not only for multiple-home owners but also among single-home owners. With the legislative notice period beginning on August 4, 2026, a tense debate between tax equity and market stabilization continues.

Controversy Over Differentiated Deductions: '1.4B for Residence' vs '900M for Non-Residence'

According to reports from Money Today and Hankyoreh on August 4, 2026, one of the biggest issues in this real-residence tax reform is the differentiated application of the basic deduction for the Comprehensive Real Estate Holding Tax. According to the Ministry of Economy and Finance, for single-home owners who actually reside in their property, the basic deduction will be raised from 1.2 billion won to 1.4 billion won. Conversely, for single-home owners who do not reside in their property, the deduction will be drastically reduced to 900 million won.

This has fueled dissatisfaction among single-home owners who, due to unavoidable reasons such as commuting or children's education, cannot reside in their own homes. Critics argue this raises tax equity issues, as these genuine buyers effectively face a tax hike simply for not residing in their property.

Shift to Long-Term Residence Deduction: Concerns for Long-Term Holders

Major changes are also expected in capital gains tax. According to reports from Biz Hankook and Yonhap Infomax on August 4, 2026, the existing 'long-term holding special deduction' will be phased out by 2029, transitioning to a 'long-term residence income deduction' (8% per year, up to 80%). Additionally, a deduction limit of 2 billion won in 2028 and 1 billion won in 2029 will be newly established to prevent excessive benefits for high-priced homes.

• Impact on Long-Term Holders: Concerns are mounting that retirees and others who have held homes for decades but failed to meet the long-term residence requirement could face a massive tax burden.
• Temporary Grace for Multiple-Home Owners: Meanwhile, the heavy capital gains tax rate for multiple-home owners in regulated areas will be temporarily eased until 2028 to induce properties onto the market. Critics point out the paradox that multiple-home owners might find themselves in a more advantageous tax position than non-residing single-home owners.

Legislative Outlook and Congressional Variables

According to analysis by MSToday and others on August 4, the government's real-residence tax reform plan will go through a legislative notice period until August 20 and is expected to be submitted to the National Assembly in early September. However, the final parliamentary review process remains the biggest variable. Opposition parties are protesting the expansion of the holding tax deduction as a tax cut for the rich, while voices within the ruling party are calling for supplementary measures for non-residing single-home owners. Significant friction and revisions are deemed inevitable during the regular National Assembly session in September.
