Understanding Korea's Inheritance Tax for Non-Resident Foreigners


Inheritance tax is a complex subject, especially for non-resident foreigners dealing with assets in Korea. In this article, we’ll break down the essential information you need to navigate this process effectively. Whether you’re an heir, estate planner, or someone looking to understand Korea's taxation system, this guide will clarify the key aspects of inheritance tax for non-residents.

🏛️ Introduction to Korea's Inheritance Tax

Korea’s inheritance tax applies to assets transferred to heirs after a person’s death. Non-resident foreigners may find themselves subject to this tax if the deceased owned property or assets within Korea.

Why Is This Relevant?

For non-resident foreigners, understanding the tax implications ensures compliance with Korean law and helps in effective estate planning. The tax is not limited to Korean citizens—foreigners with assets in Korea also fall under its scope.

Scope of Taxation

The inheritance tax for non-residents primarily applies to:

  • Real estate properties in Korea

  • Korean financial assets

  • Shares in Korean companies

  • Any tangible or intangible property located in Korea

📌 Key Components of Korea's Inheritance Tax

1. Who Is Subject to the Tax?

  • Non-Resident Deceased: If the deceased was a non-resident but held assets in Korea, these assets are subject to inheritance tax.

  • Heir's Residency: The residency status of the heir does not exempt them from tax obligations in Korea if the inherited assets are based in the country.

2. Tax Rates

Korea’s inheritance tax is progressive, ranging from 10% to 50% based on the value of the estate. The highest rate applies to estates exceeding ₩3 billion (~$2.25 million USD). Below is a breakdown:

  • Up to ₩100 million: 10%

  • ₩100 million–₩500 million: 20%

  • ₩500 million–₩1 billion: 30%

  • ₩1 billion–₩3 billion: 40%

  • Over ₩3 billion: 50%

3. Deductions and Exemptions

Non-residents may be eligible for limited deductions:

  • Basic Deduction: ₩200 million


4. Valuation of Assets

The value of inherited assets is assessed based on fair market value at the time of the deceased’s death. In the case of real estate, official appraisals are often required.

🔍 Steps for Filing Inheritance Tax in Korea

1. Declaration and Filing

  • The heir or executor must file an inheritance tax return within 9 months of the deceased’s passing.

  • Filing is mandatory even if no tax is due, ensuring compliance and avoiding penalties.

2. Payment of Taxes

  • Taxes must be paid in Korean Won.

  • Payments can be made via bank transfer, or in certain cases, installment plans may be arranged for large sums.

3. Foreign Exchange Considerations

Non-residents should be aware of currency exchange laws when transferring funds to or from Korea to settle tax liabilities.

4. Documentation Requirements

Key documents include:

  • Death certificate

  • Asset valuation reports

  • Proof of relationship to the deceased

  • Tax identification number (TIN) or alien registration number (if applicable)

🔑 Challenges and Solutions for Non-Residents

1. Double Taxation

Some countries have tax treaties with Korea that prevent double taxation. Check whether your country has such an agreement and consult a tax advisor.

2. Legal Assistance

Navigating inheritance laws in a foreign country can be daunting. Engaging a legal expert or tax consultant familiar with Korean tax laws is highly recommended.

3. Language Barrier

Official documents and communications with tax authorities are primarily in Korean. Hiring a bilingual professional ensures accurate filing and compliance.
