Korean housing holding taxes in 2026: separate property tax and comprehensive tax

Review property tax by home and comprehensive real-estate holding tax by each person's nationwide holdings. Their deductions and taxable bases differ. Do not calculate comprehensive tax by simply adding property-tax bills again.

One person owning two homes and spouses sharing a home can face different calculations despite the same total official value. This guide organizes 2026 housing-tax inputs and works through a comprehensive-tax base and pre-credit amount. Final liability requires the overlapping property-tax credit and individual adjustments.

Which value and whose ownership belong in the record?

Start with ownership at the annual June 1 assessment date. Record that year's official assessed value, ownership share and housing count, not an asking price. Shares held by one person in different regions may be aggregated nationwide for comprehensive tax. Do not automatically combine spouses' holdings as if owned by one person.

NTS lists a KRW 900,000,000 housing deduction generally and KRW 1,200,000,000 for a qualifying one-household, one-home owner. Corporations and land follow separate systems. Consult the NTS comprehensive real-estate-tax overview, other family holdings and any special-treatment application.

A zero housing comprehensive-tax base in B does not remove property tax. That is why the two taxes must be separated. The examples assume no other property or unusual legal arrangements.

Which ratio applies to the property-tax base?

The general housing ratio is 60%. A home legally recognized as one-household, one-home in 2026 instead uses 43% for official value up to KRW 300 million, 44% above KRW 300 million through KRW 600 million, and 45% above KRW 600 million. This selects a ratio for the home; it is not a progressive rate applied separately to slices. See Article 109 effective July 2026.

For one home in A under the general ratio, KRW 800 million×60%=KRW 480 million. Before relief and limits, ordinary principal property tax is 570,000+(480,000,000−300,000,000)×0.004=1,290,000 won. Two identical homes give KRW 2,580,000. Urban-area charges, local education tax, relief and tax-base limits have not yet been applied.

How do you calculate comprehensive-tax base and pre-credit tax?

NTS applies 60% to the amount after the housing deduction. A's base is (KRW 1.6 billion−KRW 900 million)×60%=KRW 420 million. It differs from the KRW 480 million property-tax base for each home. See the NTS calculation and rate guide.

Under the up-to-two-homes schedule, applying 0.5% to the first KRW 300 million and 0.7% to the remaining KRW 120 million produces 1,500,000+840,000=KRW 2,340,000. This is a pre-credit calculation step, not the final bill. The overlapping property-tax credit, applicable credits and burden limits, and special rural tax require separate consideration.

Subtracting the entire property-tax bill is also incorrect: the overlapping amount is calculated under statutory rules. Manually subtracting a credit already reflected in the notice would deduct it twice.

Practical insight: connect a home-by-home table to a person-by-person table

The first table records each address, official value, share and property-tax details. The second records each owner's total value of shares and applicable deduction. A combined two-home value loses ownership information; property-tax notices alone do not show nationwide aggregation. In A, KRW 480 million starts the calculation for one home's property tax, while KRW 420 million starts one person's comprehensive tax. Preserve those column labels even when amounts look similar.

A title transfer or gift can create other taxes and registration costs. Do not use this worksheet alone to choose a tax-saving transaction. Prepare official values, shares, previous notices and housing-count evidence to ask the relevant tax authority precisely why amounts differ.

Frequently asked questions

Q. Does a KRW 1.1 billion home have no comprehensive tax?

That describes the example only when the KRW 1.2 billion one-home deduction requirements are met. Other holdings and ownership structure matter.

Q. Why can comprehensive tax follow property tax?

They have different tax structures. A statutory credit addresses overlapping property tax rather than simply charging the full amount twice.

Q. Are spouses' shares always combined?

The starting framework is person-by-person. Joint-owner one-home special treatment and household eligibility need separate review.

Q. Should I also use a 44% ratio for comprehensive tax?

No. The relevant amounts and ratio provisions differ. Keep the per-home property-tax and per-person comprehensive-tax tables separate.

Q. Is KRW 2,340,000 the actual comprehensive-tax bill?

No. It is before the overlapping property-tax credit and other adjustments. Label it as an intermediate step when comparing a notice.

Q. Can this calculation justify changing ownership immediately?

No. Acquisition, gift or transfer taxes and legal rights may change. Review the full personal cost with appropriate professional advice.

Keep two verification tables

Fill both tables with your own data: property-level property tax address | owner and share on June 1 | assessed value | ratio and cap | principal tax | education tax | urban-area charge | local facility tax | July/September payment; person-level comprehensive property tax owner | national housing share | housing count | 900m/1.2bn deduction eligibility | ratio | tax base | rate band | property-tax credit | final check. Do not put 800m×60%=480m and (1.6bn−900m)×60%=420m in the same cell. Reconcile each table with the tax authority and local-tax notice separately.
