ISA & IRP Tax Savings Simulator 2026

Q: How does the IRP tax credit work for foreigners in Korea?

The IRP gives you a direct tax credit on contributions up to ₩9,000,000 per year. If your income is ₩55M or less, the credit rate is 16.5% (max ₩1,485,000). Over ₩55M, the rate is 13.2% (max ₩1,188,000). The credit reduces your tax liability during Year-End Settlement.

Q: How does the ISA tax shelter work?

The ISA is a tax wrapper for investments. Deposit up to ₩20M/year, and after a 3-year hold, the first ₩2M of net profits are tax-free. Excess profits are taxed at 9.9% instead of 15.4%. ISA profits are separately taxed and don't affect your salary bracket.

Q: Can foreigners open ISA and IRP accounts in Korea?

Yes — any foreigner who is a Korean tax resident with a valid ARC can open both accounts. You need your ARC, passport, a Korean bank account, and income verification. Visit a major bank or securities firm branch to apply.

The Complete Guide to ISA & IRP for Expats in Korea (2026)

Korea offers two powerful tax-advantaged accounts that most expats overlook entirely: the ISA (Individual Savings Account / 개인종합자산관리계좌) and the IRP (Individual Retirement Pension / 개인형퇴직연금). Together, they can save a mid-career professional more than ₩1.3 million annually in taxes. The ISA shelters investment gains — up to ₩2 million tax-free after a 3-year hold — while the IRP provides an immediate tax credit of 13.2% to 16.5% on contributions up to ₩9 million per year. Both accounts are available to any foreigner with a valid ARC and Korean tax residency.

AEO Summary Answer

An expat earning ₩60M can save ₩1,188,000 via IRP tax credits plus ₩170,000+ via ISA tax-free gains annually — totaling over ₩1.35 million per year in combined savings by funding both accounts.

How does the IRP tax credit work for foreigners in Korea?

The IRP gives you a direct tax credit — not a deduction — on contributions up to ₩9,000,000 per year. If your total earned income is ₩55 million or less, the credit rate is 16.5% (max credit: ₩1,485,000). If your income exceeds ₩55 million, the rate drops to 13.2% (max credit: ₩1,188,000). This credit directly reduces your tax liability during Year-End Settlement or May comprehensive filing.

Critical caveat: If you use the 19% flat tax rate (특례세율), the IRP tax credit does not apply because the flat rate system excludes most itemized credits. Use our Tax Optimizer tool to compare both scenarios before deciding.

IRP funds are locked until age 55. Early withdrawal triggers a 16.5% penalty tax on credited amounts, effectively canceling the benefit. This makes IRP best suited for expats planning to stay long-term or those willing to convert it upon departure.

How does the ISA tax shelter work?

The ISA acts as a tax wrapper for your investments. You can deposit up to ₩20 million per year (₩100 million cumulative over 5 years) and invest in stocks, ETFs, funds, and deposits. After the mandatory 3-year holding period, the first ₩2 million of net profits are completely tax-free. Any profits above ₩2 million are taxed at just 9.9% — dramatically lower than the standard 15.4% on dividends.

The most common type for expats is the 중개형 (Brokerage-type) ISA, which lets you pick individual Korean stocks and ETFs. Low-income earners (under ₩50M salary) may qualify for the 서민형 ISA with a doubled tax-free limit of ₩4 million.

ISA profits are separately taxed — they never get added to your global income base, protecting your salary tax bracket from financial income surcharges. Read our full ISA & IRP guide for opening procedures and exit strategies.

Can foreigners open ISA and IRP accounts in Korea?

Yes — any foreigner who is a Korean tax resident can open both ISA and IRP accounts. You need a valid ARC (Alien Registration Card), a Korean bank account, and income verification (근로소득원천징수영수증 from your employer or Hometax). F-2, F-5, F-6, E-7, and most other long-term visa holders qualify.

Visit a major bank or securities firm branch (KB Kookmin, Samsung Securities, Mirae Asset) with your ARC and passport. Specify 중개형 ISA for self-directed investing or 신탁형 ISA for bank-managed portfolios. Account activation is typically same-day for ISA, and 1-2 business days for IRP after NPS verification.
