Claim your pension back when you leave

If you worked in Korea on a payroll contract, both you and your employer paid into 국민연금, the National Pension Service. When you leave the country permanently, some nationalities receive that money back as a lump sum. Others do not — not because Korea kept it, but because their country has an agreement with Korea that keeps the contribution credit alive for a future foreign pension. Which side of that line you sit on decides everything else.

Two categories of country

Korea's Nationality-based treatment of foreign NPS members falls into three practical buckets. The exact assignment for your nationality is set on the NPS foreigners page and can change; use this only as an orientation.

• Refund-eligible. Nationals of countries with a lump-sum-refund provision, or where reciprocity applies, receive the full lump sum on departure. This has historically included nationals of the United States, Canada, India, the Philippines, Thailand, Indonesia, Vietnam and several others.
• Not refund-eligible; credit transferred. Nationals of countries whose social-security agreement transfers Korean contributions as credit toward the foreign pension. Contributions do not disappear — they count toward the qualifying period for a pension paid by the other country. Germany, France, the UK, several other European countries, Australia and Japan have historically been in this bucket in various forms.
• Not refund-eligible; no transfer. A small number of nationalities have neither refund nor totalization. Contributions remain in the NPS record and can be claimed if the person returns to Korea and eventually qualifies for a Korean pension.

How the amount is calculated

The lump-sum refund is the sum of:

• Your own employee contribution (currently 4.5% of insured monthly salary, employer matches with a further 4.5% — the total 9% is the NPS rate).
• The employer's matching contribution attributable to your account.
• Interest accrued from the date of contribution to the date of payment, at rates set periodically by NPS.

Contributions accrue on the insured monthly income, which is capped and floored by NPS; very high salaries do not increase the contribution above the ceiling.

Timing: start before you fly

Applications can be filed at a NPS branch in person before departure, at Incheon airport's NPS counter on the day of departure for some cases, or from abroad after leaving. In practice, the smoothest path is:

1. Two weeks before departure, visit an NPS branch with the documents below.
2. NPS calculates the refund and confirms the Korean bank account the payment will land in.
3. Payment is made after departure is confirmed — usually to a Korean bank account you keep open for the purpose, which you then close remotely, or to a designated foreign account under the electronic-remittance procedure.

Claims from abroad are possible but slower and involve consular certification of departure. In-person filing before departure is meaningfully faster.

Documents to bring

• Application for lump-sum refund (반환일시금 지급청구서), obtainable at any NPS branch or in the NPS mobile service.
• Passport (original) and residence card.
• Flight ticket showing the departure date, or, if applying from abroad, proof of departure (immigration record and a certificate of foreign resident registration marked as departed).
• Bank account information for the payment — either a Korean account or a designated foreign account with SWIFT and IBAN details.
• Where the refund is being paid to someone other than the applicant (rare), a power of attorney and identification of the recipient.

Tax on the refund

The lump sum is treated as retirement income for Korean tax purposes and is subject to withholding at a percentage set by the tax rules for retirement income. For nationals of countries with a Korea tax treaty, the withheld tax may be creditable against home-country tax on the same income; the mechanism is your home country's foreign-tax-credit provision, not a refund from Korea.

Where people get sent home — or lose money

• Claiming after closing the Korean bank account. Payment routes through a Korean IBAN by default; without one, the process moves to a foreign-remittance route that adds time and paperwork.
• Filing before you have actually left. A pre-departure claim is provisional until NPS sees the departure confirmed; move-out timing matters.
• Assuming eligibility. Nationals of totalization countries sometimes discover on departure day that they cannot take the lump sum — the credit is real, but not liquid.
• Waiting until you get home to start. Foreign-side documentation and postal times can stretch a two-week job into six months.

Common questions

Can I claim if I am on an ARC that has not expired?

You claim on the basis of permanent departure, not visa expiry. The residence card is cancelled at immigration on departure; that is the event that unlocks the lump-sum claim.

Can I combine my Korean contributions with a foreign pension later?

If your country has a totalization agreement, yes — Korean contributions can count toward the qualifying period for a pension paid by the other country, subject to the specific agreement's terms.

What if I might come back to Korea later?

Claiming the lump sum extinguishes your Korean pension record for the contributed period. If you return and re-enrol, contributions start fresh. If there is a realistic chance of long-term return, some foreign residents choose not to claim and keep the credit.

Can my employer claim on my behalf?

No. The claim is personal to the contributor. Employers can help gather documents but cannot file for you.
