Korean Inheritance and Gift Tax for Foreign Residents: What Your Residency Status Changes

Your residency status, not your visa type, not your nationality, determines how Korean inheritance and gift tax (상속세·증여세) applies to you. A foreign national who is a Korean tax resident at the time of a death or gift owes Korean tax on worldwide assets. A non-resident owes Korean tax only on assets located in Korea. This one distinction changes the tax bill, the available deductions, and the filing obligations completely.

Resident or non-resident: the question that determines everything

Korean inheritance and gift tax law classifies every person as either a resident (거주자) or a non-resident (비거주자). This classification is made at the moment inheritance starts (the date of death) or on the date a gift is made.

You are a resident if:

• You have a registered domestic address (주소) in Korea, or
• You have maintained a place of residence (거소) in Korea for 183 days or more.

This is the same 183-day threshold used in Korean income tax law. Visa type and nationality play no role.

If you are a resident when you receive an inheritance: All inherited property, both inside and outside Korea, is subject to Korean inheritance tax.

If the decedent was a non-resident: Only property physically located in Korea is subject to Korean inheritance tax.

The same scope rule applies to gift tax:

If you are a resident when you receive a gift: Gift tax applies to all donated property, regardless of where the donor lives or where the money originates.

If you are a non-resident when you receive a gift: Gift tax applies only to donated property located in Korea.

This asymmetry catches many foreign residents off guard. Being resident in Korea makes you liable for Korean tax on assets and transfers that are entirely abroad.

The rate schedule: same table for inheritance and gift tax

Both inheritance tax (상속세) and gift tax (증여세) use the same five-bracket progressive rate table. These rates apply to the taxable amount after deductions (as of 2026, verify the current brackets at nts.go.kr):

Progressive deductions (누진공제) apply at each bracket so you pay the marginal rate only on the amount within that band, not on the full taxable amount at the highest applicable rate.

A 3% filing credit (신고세액공제) reduces the calculated tax when you file an accurate return on time. This applies to both inheritance and gift tax.

Inheritance tax deductions: what residents get, what non-residents do not

Most inheritance tax deductions are available only when the decedent was a resident. Non-resident estates are treated far less generously.

When the decedent was a resident

Heirs can choose the larger of two approaches:

• Lump-sum deduction (일괄공제): ₩500 million. This is the practical choice for most small and mid-size estates because it is simpler and often larger.
• Sum of individual deductions: Basic deduction ₩200 million, plus per-child deduction (₩50 million per child), minor deduction (₩10 million multiplied by remaining years until age 19 for each minor heir), and other eligible deductions.

The spouse deduction (배우자공제) is calculated separately and added on top. A surviving spouse who actually inherits receives a deduction of at least ₩500 million (if they inherit that amount or less) or the full inherited amount up to a ceiling of ₩3 billion.

A financial assets deduction (금융재산상속공제) is also available for resident estates, up to ₩200 million, based on net inherited financial assets.

Funeral expenses are deductible for resident estates.

When the decedent was a non-resident

Only the basic deduction (기초공제) of ₩200 million applies. No lump-sum deduction, no spouse deduction, no per-child deduction, no financial assets deduction, and no funeral expense deduction.

Debts are deductible only if they are secured by a mortgage on Korean-situs property. General unsecured debt is not deductible.

The practical effect: a resident estate with a surviving spouse could shelter ₩3.5 billion or more from tax before the rate schedule applies. A non-resident estate shelters only ₩200 million.

---

Gift tax exemptions: the 10-year cumulation rule

Gift tax exemptions (증여재산공제) apply over a rolling 10-year window, by relationship category. The exemption is not per-gift. All gifts from the same relationship category within 10 years are added together and compared against one ceiling.

None of these exemptions apply when the recipient is a non-resident. A non-resident receives a gift of Korean-situs property and owes gift tax from the first won.

The 2024 marriage and childbirth addition

An additional deduction of up to ₩100 million is available for gifts received from a direct-line ascendant within two years before or after marriage registration, or within two years after the birth of a child. Confirm the exact cumulation with the standard ₩50 million lineal-ascendant deduction at nts.go.kr before you rely on it.

The remittance question: why a bank transfer from your parents can trigger gift tax

This is the scenario that surprises foreign residents most often.

If you are a Korean tax resident (183+ days in Korea) and your parents send you money from abroad, that transfer is a taxable gift in Korea. The origin of the money does not matter. The location of the donor does not matter. Your resident status means Korea has taxing rights on worldwide gifts you receive.

Here is a concrete example. You have lived in Korea for two years. Your parents send you ₩80 million from Vietnam to help with a jeonse (전세) deposit. Your prior gifts from your parents in the last 10 years total ₩0.

The ₩50 million lineal-ascendant exemption applies. The taxable amount is ₩30 million. At a 10% rate on the first ₩100 million, the gift tax before the filing credit is ₩3 million.

You must file a gift tax return within 3 months of receiving the transfer.

Bank reporting of a transfer is not a tax exemption. Large cross-border transfers are reported to Korean financial authorities under foreign-exchange monitoring rules. That is a financial monitoring step, not a tax threshold. It does not create or remove a gift tax obligation.

Filing deadlines and how to file

Inheritance tax

File within 6 months of the last day of the month in which death occurs.

For example: if the death occurs on March 15, the filing deadline is September 30.

When the decedent or all heirs are non-residents, this extends to 9 months. The exact condition triggering the extension (whether it requires the decedent alone, all heirs, or some combination to be non-resident) should be confirmed at nts.go.kr or from the Korean-language text of the Act at law.go.kr, which is the authoritative source.

File at the tax office (세무서) with jurisdiction over the decedent's last domestic address. If the decedent's address was overseas, file at the tax office with jurisdiction over the principal inherited property.

Gift tax

File within 3 months of the last day of the month in which the gift is received.

For example: if the gift is received on February 10, the filing deadline is May 31.

If the recipient is a non-resident, file at the tax office with jurisdiction over the donor's address. If both donor and recipient are non-residents, file at the tax office where the gifted property is located.

Hometax

Both inheritance and gift tax can be filed electronically through Hometax (홈택스) at hometax.go.kr. The NTS customer line for tax questions is 126.

Installment options for large inheritance tax bills

When inheritance tax exceeds ₩10 million, two-month installment payment (분납) is allowed. When it exceeds ₩20 million, extended installment payment (연부연납) over multiple years with collateral is available. Confirm the current terms at the NTS Inheritance Tax Payment page (as of 2026, verify at nts.go.kr).

Four scenarios for foreign residents

You are a foreign resident in Korea and your Korean spouse dies

If your spouse was also a resident of Korea, the entire worldwide estate is subject to Korean inheritance tax. As the surviving heir, you are entitled to the full spouse deduction (minimum ₩500 million, up to ₩3 billion on the actual inherited amount). Nothing in the Act restricts this deduction based on the heir's nationality. Confirm there is no nationality-based carve-out at nts.go.kr or with a tax professional for your specific situation.

You are a non-resident abroad and inherit Korean property

Only the Korean property is taxed. You receive the ₩200 million basic deduction only. File within 9 months if you or the decedent were non-residents. File at the tax office with jurisdiction over the inherited property.

You are a Korean resident receiving money from overseas family

This is the remittance scenario above. You owe Korean gift tax on amounts above the relevant exemption. File within 3 months of receiving the transfer.

You are a Korean resident who wants to send money to family abroad

When a Korean-resident donor (Korean or foreign national) gifts overseas property to a non-resident recipient, the donor may owe Korean gift tax under the International Tax Adjustment Act (국제조세조정에 관한 법률). If the foreign country also taxes the same transfer, a foreign tax credit may be available to avoid full double taxation. Consult a Korean tax accountant (세무사) before making large transfers.

---

Double taxation and tax treaties

Korea does not have a bilateral inheritance or gift tax treaty with the United States. US nationals resident in Korea who receive an inheritance or gift may owe taxes to both Korea and the US on the same assets, with no treaty mechanism to prevent it. A foreign tax credit may reduce one side.

Korea's income tax treaties with more than 100 countries generally do not extend to inheritance or gift tax. To check whether your home country has an applicable treaty, use the NTS treaty search or consult a Korean tax accountant.

The Inheritance Tax and Gift Tax Act does include a foreign tax credit mechanism: if you paid foreign inheritance or gift tax on the same assets, you may be able to claim a credit to avoid full double taxation. Confirm the exact articles and how the credit applies to your case at nts.go.kr or with a tax professional.

Proposed reforms: not yet law

The Korean government announced plans in early 2025 to replace the current estate tax model with an inheritance acquisition tax (유산취득세) model by 2028. Under the proposed system, each heir would be taxed on only their individual share of the estate, not the total estate, with a minimum personal deduction of ₩1 billion per heir.

A possible carve-out for short-term foreign residents (those who have been in Korea for 5 years or less within the past decade) was also reported, which would limit their liability to Korean-situs assets even if they are resident. This provision was reported in Korea Herald but details from the bill text are not confirmed.

A proposal to abolish inheritance tax on assets passed between spouses was put forward but had not passed as of mid-2025.

None of these reforms is current law. Do not rely on them for planning. Monitor the National Assembly for any enacted changes.

Where to get help

Inheritance and gift tax situations for foreign residents can be complex, particularly when assets span multiple countries or when residency status is ambiguous. These resources are the starting points:

• NTS Hometax: hometax.go.kr (electronic filing for both inheritance and gift tax)
• NTS customer line: 126 (Korean; English assistance may be limited)
• KLRI English translation of the Act: elaw.klri.re.kr (reference only; Korean text at law.go.kr is authoritative)
• Korean tax accountant (세무사): for cross-border situations, treaty questions, or any estate with assets in more than one country

FAQ

Does Korean inheritance tax apply to my overseas bank accounts if I live in Korea?

Yes. A Korean tax resident who dies owning overseas bank accounts, overseas property, or overseas investments owes Korean inheritance tax on all of it. The estate's total worldwide assets are the starting point for the calculation. Deductions reduce the taxable amount before the rate schedule applies.

My parent lives in the US and wants to send me money for a house deposit. Do I owe Korean tax?

If you are resident in Korea (183+ days), the transfer is a gift from a lineal ascendant. The first ₩50 million cumulated across all gifts from your parents in the past 10 years is exempt. Amounts above that are taxable at progressive gift tax rates. File the gift tax return through Hometax within 3 months of receiving the money.

What is the gift tax exemption for a married couple?

A spouse can give up to ₩600 million over a rolling 10-year window without gift tax. This applies when both spouses are resident in Korea. If the recipient spouse is a non-resident, the ₩600 million exemption does not apply.

I am leaving Korea permanently. Do I need to do anything about inheritance or gift tax before I go?

If you received a gift while resident in Korea and did not file a gift tax return, that obligation does not disappear when you leave. Outstanding gift tax returns should be filed before departure. If you will have ongoing Korean tax matters after leaving, appoint a tax manager (납세관리인) through the NTS before you go.

Can a non-resident heir receive a full inheritance in Korea without any Korean tax?

Not if the estate includes Korean-situs property. Korean inheritance tax applies to Korean-situs property whenever the decedent was a resident or the property is located in Korea. A non-resident heir on a non-resident decedent's estate still owes Korean inheritance tax on the Korean property, with only the ₩200 million basic deduction available.

Where exactly do I file gift tax if both me and the donor are outside Korea?

If both the donor and recipient are non-residents and the gifted property is in Korea, file at the tax office with jurisdiction over the property's location. Confirm the current filing address with the NTS at 126 or through Hometax before submitting.

How do I know if my home country has a tax treaty covering inheritance or gift tax with Korea?

Check the NTS treaty list at nts.go.kr/english and identify your home country. Most Korean tax treaties cover income tax only. Consult the specific treaty text or a Korean tax accountant (세무사) to confirm whether inheritance or gift tax is covered. If no treaty exists, you may owe tax in both countries on the same assets.

Is a reported bank transfer the same as a tax-free gift?

No. Bank reporting of an international transfer is a financial monitoring step, separate from gift tax. Even a modest transfer from your parents can trigger gift tax if you are resident in Korea and the cumulative total from them over the past 10 years exceeds ₩50 million.
