Comprehensive Real Estate Tax: ₩1.2B Deduction Kept

The government has withdrawn its plan to reduce the basic comprehensive real estate holding tax deduction for single-home owners who do not reside in the home to 900 million won. The combined deduction for jointly owned homes will remain at 1.2 billion won. The tax burden cap will also remain at the current 150%, while the proposal to expand the deduction for owner-occupants will continue to move forward.

Based on the revised government tax reform proposal as of September 2026

Key Points of the Revised 2026 Comprehensive Real Estate Holding Tax Proposal

The main point of this revision is the reversal of some proposals that would have increased the tax burden. The deduction for single-home owners who do not reside in the home and the tax burden cap will remain unchanged. Here, non-occupancy means not actually living in the home concerned.

The revised government proposal in the table is not a law that takes effect immediately. Tax law revisions require deliberation by the National Assembly and statutory amendments. When filing, taxpayers must check the laws applicable to the relevant tax year.

The exact official wording should be checked in the Ministry of Economy and Finance’s revised materials for the 2026 tax reform proposal. Whether the changes have taken effect can be cross-checked against the Comprehensive Real Estate Holding Tax Act on the Korean Law Information Center. Individual eligibility criteria should be verified through guidance from the National Tax Service.

Deduction Criteria by Circumstance

How the rules apply varies depending on actual occupancy and the form of ownership. The revised proposal withdrew the planned reductions for non-occupants and joint owners. The proposed deduction increase for owner-occupants with one home remains in place.

The final tax amount is not determined solely by whether the owner actually resides in the home. The officially assessed value and ownership share also affect individual calculations. The tax classification must be determined based on the final law and National Tax Service criteria.

Example of Calculating the Tax Burden Cap

The tax burden cap limits sharp year-on-year increases in property holding taxes. The revised government proposal retains the cap at 150%. The following is a simplified example provided in the announcement.

1. Assume that last year’s combined property tax and comprehensive real estate holding tax totaled 1 million won.
2. This year’s calculated property holding taxes total 2 million won.
3. Applying the 150% cap limits the amount payable to 1.5 million won.
4. Under the original 200% proposal, the full calculated amount of 2 million won would apply.

The difference resulting from the revised cap in this example should be checked in the Ministry of Economy and Finance’s revised tax reform proposal materials. It does not represent the tax reduction for every taxpayer. If this year’s calculated tax is below the cap, the cap has no limiting effect.

Why a 1.2 Billion Won Deduction Does Not Mean a 1.2 Billion Won Tax Reduction

The basic deduction is not an amount directly subtracted from the tax payable. It is the threshold used to determine the taxable amount from the officially assessed value. Therefore, the deduction amount and the actual tax savings are different.

For comprehensive real estate holding tax calculations, the amount remaining after the deduction is the starting point. The fair market value ratio and tax rate are then applied. At the final stage, the applicable tax burden cap is reviewed.

• A 1.2 billion won deduction does not mean eliminating 1.2 billion won in taxes.
• Even with the same officially assessed value, ownership and occupancy conditions may differ.
• If the fair market value ratio rises, the taxable amount may increase.
• The exact tax must be calculated using the statutory formula for the relevant year.

Comprehensive Real Estate Holding Tax Reforms That Were Not Withdrawn

The entire comprehensive real estate holding tax reform proposal was not withdrawn. The proposal to raise the deduction for owner-occupants with one home to 1.4 billion won remains in place. The policy direction of strengthening taxation on high-value homes was also retained.

The final tax rates and ratios depend on statutes and subordinate regulations. An individual’s tax liability cannot be finalized based solely on the government proposal. The details may change again during National Assembly deliberations.

Order for Checking the Government Proposal and Applicable Law

When assessing taxes, the announced proposal must be distinguished from the law in force. A government proposal presents the direction of a planned amendment. Actual tax obligations are determined under the laws currently in effect.

1. Check whether the home is solely or jointly owned.
2. Determine whether the owner actually resides in the home.
3. Check the Ministry of Economy and Finance materials for changes to the government proposal.
4. Check the final amended law on the Korean Law Information Center.
5. Cross-check the calculation criteria for the relevant tax year in National Tax Service guidance.

After receiving a tax notice, first check the tax year stated on it. Applying a deduction from a different year will change the calculation. It is safer not to assume the amount payable based only on a government announcement.

Common Mistakes

The most common misunderstanding is treating 1.2 billion won as a tax credit. Some also interpret the 150% cap as meaning that taxes can rise by only 50%. Another mistake is assuming that the government proposal is already in force.

• Do not confuse a single-home owner who does not reside in the home with an overseas nonresident under tax law.
• Do not subtract the basic deduction directly from the tax payable.
• Do not treat the tax burden cap and the comprehensive real estate holding tax rate as the same concept.
• Do not assume that the revised government proposal is a finalized law in force.
• Do not skip individual calculations based only on the combined deduction for joint owners.

The tax burden cap is a mechanism that limits the extent of an increase. It does not refer to the tax rate or deduction itself. The final amount payable must be checked using each individual’s tax assessment information.

Will the deduction for single-home owners who do not reside in the home be reduced to 900 million won?

The revised government proposal withdrew the plan to reduce it to 900 million won. The deduction is intended to remain at the current 1.2 billion won. The amended law must be checked to confirm whether it ultimately applies.

Is the deduction for owner-occupants with one home also 1.2 billion won?
