Finding Forgotten Money in Korea (Official Services Only)

All screenshots are public pages captured on 2026-10-26; diagrams are self-made illustrations.

Old bank accounts, unclaimed tax refunds — you may have money you forgot about. You can check through official public and financial services.

Who this is for

• People who can’t remember all their old accounts
• People who moved or changed accounts and may have missed a refund
• Families checking an inheritance

Step 1. See all your accounts with AccountInfo

Based on the Korea Financial Telecommunications & Clearings Institute’s official AccountInfo page.

• See your bank accounts, cards and insurance in one place.
• Small, inactive accounts can be closed or moved right away.
• For Korean nationals aged 19+.
• Checking and transfers happen after identity verification (login). Help: KFTC customer center 1577-5500.

Step 2. Dormant money finder (Korea Inclusive Finance Agency)

Based on the agency’s official page.

• Money becomes “dormant” after: deposits 5 years, insurance payouts 3 years, cashier’s checks 5 years, unclaimed stock dividends 10 years.
• You can apply online for up to 20 million won in your own name (the dormant-money website or the “서민금융 잇다” app).
• You can also search via Gov24, AccountInfo, the insurance finder, and some bank apps.
• Center visits need a reservation via 1397.
• Heirs can search too.
• Applying happens after identity verification (login) (official page: online applications up to 20 million won).

Step 3. National Tax Service unclaimed refunds

Based on the NTS official page.

• Finds tax refunds you didn’t receive (e.g., due to account errors), within 5 years of the refund decision.
• Search with your resident registration number and name.
• Claim via Hometax/Sontax, ARS 1544-9944, or a tax office.

Step 4. Receive it into your own account

• Use only the official websites or apps (AccountInfo, the Korea Inclusive Finance Agency’s dormant-money service, NTS Hometax). Beware of phishing texts, calls and look-alike sites; no official service asks you to pay a fee or send money first.
• Be suspicious of anyone offering to “find your money” for a fee or asking for personal details.

Common mistakes

• Checking only one service (each shows different money)
• Using links from text messages — type the address or use the official app
• Giving personal info to “money finder” agents
