Post-Election Comprehensive Real Estate Tax Reform: Shifts Toward Actual Residence-Based Taxation

The Signal Flare of Real Estate Tax Reform Fired by Local Elections

With the conclusion of the June 2026 local elections, changes in tax policy to accommodate the public sentiment on real estate, which had a decisive impact on the election results, are gaining momentum. The hottest issue is undoubtedly the 'Comprehensive Real Estate Holding Tax'. Strengthened in the past during periods of soaring real estate prices under the pretext of suppressing speculative demand from multiple-home owners and enhancing tax equity, the comprehensive real estate holding tax has increasingly been cited as a core cause of tax resistance as assessed values were realized and the tax burden on single-home owners skyrocketed.

Recently, political circles and the government have formed a consensus that this punitive taxation system needs fundamental restructuring. This is because there is a growing structural awareness that the current tax system, by imposing excessive taxes on unrealized asset gains, is causing severe deterioration in cash flow for retirees with limited income or long-term single-home residents. Accordingly, the core topics of tax reform in the second half of 2026 are narrowing down to the 'normalization of punitive taxation' and the 'rational readjustment of tax burdens centered on actual residents'.

'Actual Residence' Determines Asset Value and Tax Burden

The most important principle of the real estate tax reform being envisioned by the government is 'actual residence'. Moving beyond simply how many houses one owns, whether the house meets the purpose of actual residence will become the absolute criterion determining future tax benefits and penalties.

1. Protection Stance for Single-Home Residents and Variables

The government's basic stance to ease the tax burden as much as possible for single-home households who actually reside in their property is firm. However, the market variable is that the jeonse (deposit-based lease) shortage for Seoul apartments has recently worsened, and as the buying sentiment rapidly spreads to southern Gyeonggi regions such as Dongtan and Pyeongtaek, overall housing prices have turned upward. When house prices rise, assessed values inevitably rise simultaneously.

Currently, the basic deduction amount for the comprehensive real estate holding tax for a single-home household is 1.2 billion KRW. Even if the government does not execute an explicit tax rate hike, adjusting the realization rate of assessed values and the fair market value ratio in line with the rise in house prices will raise the actual tax base, inevitably increasing the overall holding tax burden combining property tax and comprehensive real estate holding tax. Therefore, actual residents owning high-priced homes must closely monitor the trend of assessed value changes, regardless of the tax reform bill.

2. Tweezers Regulation on Multiple-Home Owners and Non-Resident Properties

Taxation on homes whose purpose of actual residence is not proven will become much sharper. A prime target is the special deduction for long-term holding of capital gains tax. Previously, substantial deduction rates applied to capital gains simply by holding the house for a long time, but in the future reform bill, a plan to significantly expand the weight of the 'actual residence period' within the total deduction rate is highly likely. In other words, for so-called 'gap investment' properties purchased for investment purposes and leased out, it may become difficult to avoid a massive capital gains tax bomb upon sale even if held for a long time. This is a strong signal to block demand utilizing housing as a means of generating profit rather than living space.

July Tax Revision Bill Announcement and Strategies for Market Participants

Relevant ministries, including the Ministry of Economy and Finance, are currently conducting in-depth research on 'measures to rationalize the real estate tax system', and plan to finalize and announce a specific 2026 tax revision bill around late July based on this. Investors and owners with a high proportion of real estate assets must complete proactive portfolio checks before the tax revision bill is announced.

• Revaluation of Actual Residence Value of Owned Homes: The future rate of return on real estate investment will be determined by 'post-tax profit' rather than capital gains themselves. For houses that cannot meet actual residence requirements, securing cash through sales or seriously considering a portfolio shift to non-residential assets before taxation is strengthened must be done.
• Inter-Family Name Distribution Simulation: The comprehensive real estate holding tax strictly follows the principle of individual taxation. A meticulous comparative calculation must be made between holding a home with an assessed value exceeding 1.2 billion KRW under sole ownership versus dividing the shares into joint marital ownership to see the difference in basic deductions and the effect of avoiding progressive tax rates.
• Trading Timing Aligned with the Assessment Date: The date of establishment of tax liability for all real estate holding taxes, including property tax and comprehensive real estate holding tax, is June 1st of every year. Therefore, if there is a plan to sell a house, adjusting the balance clearance date or the ownership transfer registration date to before the end of May next year is a core strategy to prevent unnecessary tax outflow.

In conclusion, the real estate market from the second half of 2026 onwards is facing a paradigm shift where the act of 'actual residence' itself serves as the most definitive tax tech and premium. Now, more than ever, asset optimization through sophisticated tax policy analysis rather than simply relying on expectations of rising asking prices is required.
