US taxes & Social Security when you live in South Korea
What stays true for US citizens and green-card holders no matter where they move. General information, not tax or legal advice — confirm your situation with a cross-border tax professional. Reviewed July 2026.
- As a US citizen or green-card holder you keep filing a US federal tax return on your worldwide income even while living in South Korea — the US taxes based on citizenship, not where you live (www.irs.gov/individuals/international-taxpayers/us-citizens-and-resident-aliens-abroad).
- The US and South Korea have an income tax treaty in force (www.irs.gov/businesses/international-businesses/united-states-income-tax-treaties-a-to-z). A treaty can lower withholding on cross-border income like dividends, interest and pensions and set residency tie-breaker rules — it does not remove your US filing obligation.
- Double taxation is usually avoided with the Foreign Earned Income Exclusion (Form 2555, www.irs.gov/individuals/international-taxpayers/foreign-earned-income-exclusion) and/or the Foreign Tax Credit (Form 1116); which one is better depends on your income and South Korea's tax rates.
- If your foreign bank and financial accounts exceed US$10,000 combined at any point in the year, you must file an FBAR (FinCEN Form 114, www.fincen.gov/report-foreign-bank-and-financial-accounts); larger balances can also trigger FATCA Form 8938 with your return.
- The US and South Korea have a Social Security Totalization Agreement (www.ssa.gov/international/agreements_overview.html), so you generally contribute to only one country's social-security system instead of paying into both, and coverage periods can be combined toward benefits.
Moving to South Koreafrom the US: the American's checklist
How US citizens apply, whether your license transfers, and the things that catch Americans out. Reviewed July 2026 against official sources; always confirm current requirements before you act.
Applying for a visa
US citizens can enter visa-free for up to 90 days. Long-term residency visas must be processed and applied for at a South Korean consulate in the US prior to departure.
Visa-free entry: 90 days.
Main long-stay routes: F-2-7 (Points-Based Resident Visa), E-7 (Foreign National of Ability Visa), D-8 (Corporate Investor Visa).
Your US driver's license
Exchange rules vary by local authority
Reciprocity is state-specific. Around 23 US states (e.g., TX, FL, OR) have agreements allowing direct exchange of a US license for a Korean license after a physical check-up. Others must pass the written exam.
- South Korea has strict asset reporting rules. Residents must file a report on foreign financial accounts to the National Tax Service if the value exceeds KRW 500 million.
- The US-Korea Totalization Agreement prevents double social security taxation, allowing self-employed expats to pay only into the US SECA system.
- FATCA is fully implemented; Korean banks require extensive disclosure forms from US citizens.

- Immigration and visas run through the Korea Immigration Service / Hi Korea (www.hikorea.go.kr); common routes include the D-8 (investor), D-10 (job-seeker), E-7 (skilled worker) and F-series (family/residence) visas.
- Register for an Alien Registration Card (ARC) at an immigration office within 90 days of arrival — it's needed for banking, phone contracts and most services.
- National Health Insurance (NHIS, www.nhis.or.kr) is mandatory and long-stay foreigners are auto-enrolled after 6 months; the tax authority is the NTS (www.nts.go.kr).
- Renting typically uses jeonse (a large lump-sum deposit that is refunded) or wolse (a smaller deposit plus monthly rent). Main portals: Zigbang (www.zigbang.com), Dabang. Emergency 112 (police), 119 (fire/ambulance).
- Key figures (approximate — verify current values): wolse deposits commonly run ₩5–10 million with monthly rent on top, while jeonse deposits can be tens to hundreds of millions of won; the ARC issuance fee is ~₩30,000; NHIS contributions for foreigners have a monthly minimum.

Frequently asked questions
Do I still pay US taxes if I move to South Korea?
Yes. The US taxes citizens and green-card holders on worldwide income no matter where they live, so you keep filing a federal return. The Foreign Earned Income Exclusion and the Foreign Tax Credit usually reduce or eliminate double taxation, but the filing obligation itself does not go away.
Is there a US tax treaty with South Korea?
Yes. The US and South Korea have an income tax treaty in force, which can reduce withholding on cross-border income and set residency tie-breaker rules. It does not remove your US filing obligation, and you still use the Foreign Earned Income Exclusion or Foreign Tax Credit to avoid double taxation.
Will I pay into Social Security in both the US and South Korea?
Usually no. The US and South Korea have a Social Security Totalization Agreement, so you generally contribute to only one system and can combine coverage periods toward benefits.
Do I need a visa to move to South Korea?
