How Foreign Investors Open Securities Accounts in Korea 2025: Tax Rules & Compliance Guide

How Foreign Investors Can Open a Korean Securities Account & Tax Rules

South Korea’s stock market is one of Asia’s most dynamic and attractive for global investors. Foreign participation has been steadily growing, especially after reforms simplified registration and investment processes. This guide explains how a foreign investor can open a securities account in Korea, and the tax regulations that apply to dividends, capital gains, and reporting in 2025.

1. Market Access for Foreign Investors

Until recently, foreigners needed an **Investment Registration Certificate (IRC)** issued by the Financial Supervisory Service (FSS) to trade Korean securities. However, in **December 2023**, Korea abolished the IRC system, making it much easier for overseas investors to open accounts. ([fss.or.kr](https://english.fss.or.kr))

Now, foreigners can directly open a securities account by providing key identification documents and registering with a licensed broker.

2. Required Documents to Open a Securities Account

To open a securities account in Korea, foreigners generally need:

• Valid Passport
• Alien Registration Card (ARC) – required if resident in Korea
• Korean bank account (to fund investment and withdraw proceeds)
• Tax residency certificate (if seeking double tax treaty benefits)
• Basic investor information form – filled with the securities firm

Some brokers offer online application processes, but in many cases in-person verification is still required.

3. Account Types Available

• Individual Securities Account – most common for retail investors
• Corporate / Institutional Account – for hedge funds, asset managers
• Foreign Custody Account – for institutions using global custodians

4. Tax Rules for Foreign Investors (2025)

4.1 Dividend Income Tax

• Foreigners receiving dividends from Korean companies are subject to a **withholding tax of 22% (20% income tax + 2% local tax)**.
• Under double tax treaties, this rate may be reduced to **5%–15%** depending on the country. (e.g., U.S.–Korea treaty rate: 15%).

4.2 Capital Gains Tax

• Listed stock trading by non-resident foreigners is generally **exempt from capital gains tax**, except in cases where ownership exceeds 25% or the investor is a major shareholder. ([moef.go.kr](https://english.moef.go.kr))
• For major shareholders, capital gains tax applies at **22%** (20% + 2% local tax).

4.3 Interest Income from Bonds

• Coupon interest on Korean bonds is generally subject to **15.4% withholding tax**, unless reduced under a tax treaty.

5. Compliance & Reporting

• Foreign investors must designate a local custodian (securities company or bank) to handle settlement and tax withholding.
• Most taxes are withheld at source, so additional filing is often unnecessary for non-residents unless they seek treaty benefits.
• Foreign corporations may need to submit tax forms through local agents to claim reduced treaty rates.

6. Example Scenario

A U.S. investor buys shares of Samsung Electronics:

Item	Tax Treatment	Rate
Dividends	Withholding tax at source	15% (under U.S.–Korea tax treaty)
Capital Gains	Exempt (not a major shareholder)	0%

7. Key Tips for Foreign Investors

• Work with a licensed broker in Korea who supports foreign accounts.
• Check whether your country has a tax treaty with Korea to reduce withholding rates.
• Maintain proper tax residency documents to benefit from treaty relief.
• Understand major shareholder rules to avoid unexpected capital gains tax.
• Use custodians for smooth settlement and compliance.

8. Conclusion

Korea has significantly simplified access for foreign investors by eliminating the old IRC system. Now, opening a securities account requires only basic documents and working with a licensed broker. However, investors must still be aware of tax obligations: **dividend withholding, bond interest taxation, and capital gains rules for major shareholders**. With the right preparation and treaty knowledge, foreign investors can participate smoothly in the Korean market.
