South Korea Wealth Tax Guide 2026
South Korea does not impose a net wealth tax (순자산세) on individuals' total net worth. The closest equivalent is the Comprehensive Real Estate Tax (종합부동산세, CRET), an annual national tax on high-value real estate holdings with progressive rates of 0.5–2.7%. Financial assets, cash, and other movable property are not subject to any recurring wealth tax.
No Net Wealth Tax
South Korea has considered but never enacted a net wealth tax. Unlike some European countries that tax total net worth (assets minus liabilities), Korea only taxes specific asset categories through other mechanisms. Financial investments (stocks, bonds, deposits), vehicles, art, collectibles, and business assets above real estate are not subject to any recurring wealth or net worth tax. This makes Korea a relatively favourable jurisdiction for high-net-worth individuals from a wealth tax perspective, though the real estate tax system is notably stringent.
Comprehensive Real Estate Tax (종합부동산세, CRET)
CRET is the closest South Korean equivalent to a wealth tax. It is an annual national-level tax on individuals and corporations holding real estate above certain threshold values. It is designed to curb real estate speculation and reduce wealth concentration in property. CRET is paid in addition to the local property tax (재산세).
Thresholds for 2026:
- Residential property: Aggregate standard market value exceeding KRW 900 million (KRW 1.4 billion for one-household homeowners)
- General land: Aggregate value exceeding KRW 500 million
- Residential land (separately taxed): Aggregate value exceeding KRW 800 million
Rates for residential property (2026):
- Excess up to KRW 3B: 0.5%
- KRW 3B to 6B: 0.7%
- KRW 6B to 12B: 1.0%
- KRW 12B to 25B: 1.3%
- KRW 25B to 50B: 1.5%
- KRW 50B to 94B: 2.0%
- Above KRW 94B: 2.7%
A 10% resident surtax (주민세) applies to CRET. Multi-homeowners face surcharges of 20–100% on the calculated CRET amount. Single-homeowners (1세대 1주택) may receive a rate reduction of up to 50%, with additional reductions for seniors (10–40% based on age).
How CRET Compares to a Wealth Tax
While CRET is often described as a wealth tax equivalent, there are important differences:
- Asset scope: Real wealth taxes cover all assets (cash, securities, business interests, art, etc.). CRET covers only real estate above thresholds.
- Exemptions: A net wealth tax typically has a high exemption threshold for total net worth. CRET has exemptions for property value below the threshold but does not exempt the first portion of property held — it applies only to the excess.
- Liability: CRET is levied on the property owner regardless of overall wealth. A person with a single home worth KRW 2 billion would owe CRET on KRW 600 million (2B minus 1.4B exemption), whereas someone with KRW 1 billion in stocks and KRW 800 million in real estate would owe no CRET but would have higher net worth.
- Incidence: CRET is specifically targeted at real estate, reflecting Korea's policy focus on housing affordability and land speculation.
Other Closely Related Taxes
While not a wealth tax, several Korean taxes have wealth-tax-like characteristics:
Local property tax (재산세): Annual tax on land and buildings at 0.1–0.4% of standard market value. This applies to all real estate, not just high-value holdings. Together with CRET, the total annual property tax burden on high-value real estate can reach approximately 3.5% of the property's value (pre-surcharge) in the top bracket.
Financial income taxation: Interest and dividends are taxed at 15.4% withholding, with additional tax on income exceeding KRW 10 million. This is an income tax, not a wealth tax, but it increases the effective tax burden on financial asset wealth.
Inheritance and gift tax: Progressive rates of 10–50% on wealth transfers between generations act as a deferred wealth tax. See the inheritance and gift tax guide for details.
Tax Planning Considerations
- Property vs financial assets: From a wealth tax perspective, financial assets are clearly favoured — no annual CRET-like tax applies. High-net-worth individuals may consider rebalancing toward financial investments to avoid the CRET burden on high-value real estate.
- Single home exemption: The KRW 1.4 billion threshold and reduced rates for one-household homeowners make holding a single high-value home more tax-efficient than multiple properties.
- Corporate ownership: Holding real estate through a corporation does not eliminate CRET — legal entities are also subject to CRET on real estate holdings, though different thresholds apply.
International Comparison
South Korea's approach — no net wealth tax but a strong real estate wealth tax — is relatively common among Asian economies. Japan and Taiwan similarly focus on real estate taxation rather than a comprehensive net wealth tax. In contrast, several European countries (Switzerland, Spain, Norway, the Netherlands) impose some form of net wealth tax on financial and other assets. Korea's system means that wealth concentrated in financial assets is largely free from recurring annual taxation, while real estate wealth faces a material annual charge.
FAQs
Does South Korea have a net wealth tax?
No. There is no tax on total net worth. Only real estate above certain thresholds is subject to an annual wealth-like tax (CRET).
Do I pay CRET on my apartment?
Only if the standard market value of your total residential property holdings exceeds KRW 900 million (KRW 1.4 billion if you own only one home). Most apartment owners are below this threshold and pay only local property tax.
How is CRET different from property tax?
Local property tax (재산세) applies to all real estate at low rates (0.1–0.4%). CRET (종합부동산세) is an additional national tax that only applies above the exemption threshold, at higher progressive rates (0.5–2.7%). Most homeowners pay only property tax; only those with high-value holdings also pay CRET.
Can I avoid CRET by distributing property among family members?
Gifting property to family members may trigger gift tax (증여세) and does not necessarily reduce CRET because family members' holdings may be aggregated under the anti-avoidance rules. The NTS closely scrutinises property transfers designed to stay below CRET thresholds.
