Property Tax Overview in South Korea

How are Korean annual property taxes structured?

South Korean annual property taxation operates through two layered frameworks: Local Property Tax (Jae-san-se 재산세) collected by municipal authorities and Comprehensive Real Estate Tax (CRET — Jong-bu-se 종합부동산세) collected by the National Tax Service. Local Property Tax under Article 105 of the Local Tax Act (Ji-bang-se-beob 지방세법) applies sliding rates based on property value and use category: residential property faces 0.1% (up to KRW 60 million assessed), 0.15% (KRW 60-150m), 0.25% (KRW 150-300m), 0.4% (above KRW 300m); commercial property faces flat 0.25% on land plus building rates; agricultural land receives reduced rates. Local Property Tax assessment uses publicly disclosed valuations updated annually by municipal authorities. The Local Property Tax is collected via municipal-issued payment notices typically arriving July (residential) and September (land, commercial) of each year. PwC's 2026 South Korea property-tax commentary identifies Local Property Tax as a meaningful but generally manageable annual cost for typical Korean homeowners — substantially below the layered CRET burden for high-value holdings.

What is the Comprehensive Real Estate Tax (CRET)?

The Comprehensive Real Estate Tax (CRET — Jong-bu-se 종합부동산세) operates under separate national legislation as an aggregate-residential-holdings tax beyond Local Property Tax. Thresholds: residential aggregate value above KRW 1.2 billion for single-home owners, KRW 900 million for multiple-home owners. Sliding 0.5% to 3% on the excess above threshold. The framework was substantially expanded under the Moon administration's 2020 housing-market intervention through reduced thresholds and increased rates. The Yoon administration's 2022-2024 reforms partially relaxed the CRET: increased thresholds, reduced sliding-rate-multipliers, and narrowed multiple-home-owner targeting. CRET assessment uses publicly disclosed valuations (gong-si-ga-gyeok 공시가격) updated annually by the Ministry of Land, Infrastructure and Transport — typically running 70-90% of market value providing meaningful relief versus market-rate calculation. KPMG's 2026 South Korea CRET commentary identifies the tax as a continuing political-economy concern — high-net-worth Korean homeowners and the foreign expat community routinely face substantial CRET liabilities driving consideration of corporate-structure alternatives.

What is the acquisition tax framework?

Real-estate acquisition tax (Chwi-deuk-se 취득세) under Article 7 of the Local Tax Act applies at the time of property transfer with rate tiers based on property value and ownership context. Standard residential rates: 1% (acquisition price ≤KRW 600 million), 2% (KRW 600m-900m), 3% (above KRW 900m). Commercial property faces flat 4% on the standard taxable value. The Moon administration's 2020 housing-market controls added multiple-home-buyer surcharges: +8 percentage points for 2nd home acquisition, +12 percentage points for 3rd or subsequent home acquisitions — effectively pushing total acquisition tax to 9-15.5% for multiple-home buyers in the top tiers. The Yoon administration partially relaxed the surcharges through 2022-2024: 2nd-home surcharges narrowed to specific high-cost residential areas, 3rd-home surcharges retained but with extended phase-in periods. Beyond Chwi-deuk-se, the registration tax (Deung-rok-se 등록세) at 0.6-2% on registration plus judicial-scrivener fees of approximately 0.5% in practice bring total Korean acquisition costs to approximately 5-8% of purchase price for residential and 6-10% for commercial transactions.

How are capital gains on multiple-home-owner disposals taxed?

Korean real-estate capital-gain taxation under Article 104 of the Korean Income Tax Act applies progressive 6-45% rates with substantial multiple-home owner surcharges introduced under the Moon administration's 2020 housing-market intervention. Base progressive rates flow through the standard personal income tax schedule (6% on first ₩14 million scaling to 45% above ₩1 billion) plus 10% local surcharge. Multiple-home surcharges: +10 percentage points for 2-home owners on residential disposals, +20 percentage points for 3+ home owners — pushing combined effective rates above 75% for high-bracket multi-home Korean owners during the peak Moon-era enforcement period. The Yoon administration's 2022 reform suspended the multi-home surcharges through 2025 — providing a substantial window for high-bracket multi-home owners to dispose without the surcharge burden. Holding-period reductions provide additional relief: 30% reduction for holdings exceeding 2 years; up to 80% special long-term-holding deduction for residential property held exceeding 10 years. EY's 2026 South Korea real-estate commentary identifies the multi-home surcharge framework as a continuing source of practitioner concern — the Yoon administration's 2022 suspension may not extend beyond 2025, with the framework potentially reactivating under future administrations. The Korean capital-gains crossover at /global/jurisdictions/country/kr/topic/capital-gains-tax covers the broader framework.

What is the principal-residence exemption?

The principal-residence capital-gain exemption under Article 89 of the Korean Income Tax Act provides substantial homeowner relief for qualifying single-residence holdings. Eligibility criteria: (a) the property served as the seller's principal residence at the time of disposal or within preceding qualifying period, (b) holding period exceeds 2 years (extended in specific Moon-era controls for high-cost areas), (c) the seller does not hold any other Korean residential property at time of disposal (single-home framework). The exemption operates as a full capital-gain exclusion for gains up to KRW 1.2 billion — the excess above KRW 1.2 billion faces standard progressive rates with capital-gain deductions applied. KPMG's 2026 South Korea principal-residence commentary identifies the exemption as a critical Korean homeowner benefit particularly valuable in high-real-estate-cost Seoul and Gangnam markets where typical principal-residence gains frequently approach or exceed the KRW 1.2 billion threshold. Practitioners frequently advise homeowner clients to verify single-home eligibility carefully — even short-term concurrent ownership of a second property during transition can disqualify the exemption.

How are non-resident landlords taxed?

Non-resident landlords face Korean withholding on rental income under Article 119 of the Korean Income Tax Act. Withholding rate: 22% combined (20% national + 2% local surcharge) on gross rental income paid by Korean tenants. The withholding operates as final tax for non-resident landlords without a Korean permanent establishment — no further reporting obligations on the gross-basis withholding. Alternative election: non-resident landlords may appoint a Korean tax agent (na-se-gwan-li-in 납세관리인) and file the annual personal income tax return claiming actual expense deductions (depreciation, mortgage interest, property management) on the rental income. The tax-agent option typically produces substantially lower effective rates for non-resident landlords with substantive expenses. Korean rental income calculation permits depreciation on buildings using straight-line methods with statutory useful lives (40 years for reinforced concrete, 20 years for wood-frame). The Korean expat-tax crossover at /global/jurisdictions/country/kr/topic/expat-tax-residency covers the broader non-resident framework including the 5-year-rule shelter that may protect foreign-source income.

How do international investors handle Korean property taxation?

Foreign owners of Korean real estate face Korean property taxes without residency distinction — annual Local Property Tax and CRET apply to all Korean-situs property regardless of owner residence. Acquisition tax similarly applies to all Korean-situs property purchases with the same residency-neutral framework. Income-tax exposure varies by residency: non-resident landlords face the gross-basis-withholding-or-tax-agent framework described above; non-resident sellers face Korean capital-gains tax on Korean real-estate disposals at standard rates (progressive 6-45% plus multiple-home surcharges where applicable). Treaty interaction follows OECD Model Article 13 for capital gains and Article 6 for rental income, generally assigning Korean real-estate taxation to Korea regardless of owner residence. Cross-border foreign-currency conversion for cross-border property-management flows runs cost-effectively through WorldFirst. US-source rental income reconciliation for US-citizen Korean property owners flows through Tax1099.

What compliance obligations apply to property owners?

Municipal authorities issue annual Local Property Tax assessment notices typically in July (residential) and September (land, commercial), with payment due within 60 days. CRET assessment from NTS arrives in November-December with payment due by 15 December annually. Real-estate acquisition-tax assessment from local government arrives 30-60 days after property registration. Annual personal income tax return (jong-hap-so-deuk-se sin-go) for rental income or capital-gain reporting is due 31 May following the tax year through Hometax. Property-related records retention is 5 years from the close of the fiscal year (10 years for blue-form filers and substantial-shareholder transactions). Late-payment penalties under the National Tax Basic Act reach 5% plus interest at 0.025% per day (approximately 9% per annum). Practitioners commonly recommend Korean Certified Tax Accountants (Se-mu-sa 세무사) for complex property structuring including CRET exposure analysis, multi-home surcharge management, principal-residence-exemption qualification verification, and non-resident-landlord tax-agent appointment.
