Did you know you might have unclaimed tax refunds sitting there? Income-tax and VAT refunds, EITC, overpaid local taxes — for various reasons, money you're owed sometimes never reaches your account. And after 5 years it expires. Here's how to check for unclaimed refunds in about 5 minutes.
Why refunds arise
| Type | Why |
|---|---|
| Income tax refund | Prepaid/withheld (3.3%) exceeds actual tax |
| Year-end settlement | Deductions made prepaid tax too high |
| VAT refund | Input VAT exceeds output VAT |
| Local tax overpayment | Car/property tax paid twice or wrong |
| EITC/child credit | Benefit paid after applying |
Account errors, address changes, or missed applications can leave it unpaid — so check directly. If you've moved, changed jobs/accounts, or done withholding as a freelancer, you're more likely to have some.

FAQ
Is checking free?
Yes — Hometax, WeTax, and Gov24 are all free. Beware texts/apps charging a "finder fee."
Why wasn't it deposited?
Usually a missing refund account or changed address. Register your account at Hometax.
Is a text about my refund real?
Smishing impersonating the tax office is common. Don't tap links — go to Hometax directly or call 126. The earned income and child credits are a separate pot of money worth checking in the same sitting.
Sources and where to check
- Seoul Metropolitan Government — unclaimed local tax refunds (May 2026). Seoul alone is holding 101,372 refunds worth about 12.2 billion won. They expire after five years, and you can check via ETAX, STAX, a district office or any Shinhan Bank branch.
- Financial Supervisory Service — FINE, the dormant-money portal. One place to search thirteen categories: dormant deposits and insurance payouts, unclaimed shares, overpaid car insurance premiums, card points, unclaimed money from failed institutions and unrefunded public charges.
- National Health Insurance Service — refunds of excess co-payments. You must claim within three years of receiving the claim form, and payment follows within seven days of filing.
Written as of July 2026. The scale of unclaimed local refunds, the five-year limit, FINE's coverage and the health-insurance procedure come from the sources above. Note that the expiry period differs by category — local tax is five years, but health insurance co-payment refunds expire in three. The five-year limit on national tax refunds could not be checked against a public-agency page. Amounts depend on your own lookup. Use only official channels and never enter personal data into impersonating texts or apps. See also amended returns and the tax calendar.
