Complete Guide to ETF Investing in Korean Pension Accounts (Pension Savings & IRP)

Both pension savings funds and IRP qualify as pension accounts in Korea, but they differ in eligibility and operating rules. Pension savings funds are open to anyone with an annual contribution cap of KRW 18 million. IRP is available to employed workers and self-employed individuals, with contributions combined with pension savings up to KRW 18 million annually.

The tax deduction cap is KRW 6 million for pension savings alone, or up to KRW 9 million including IRP (as of 2024). Taxpayers with total salary below KRW 55 million (or comprehensive income below KRW 45 million) receive a 16.5% tax credit, while those above receive 13.2%. For example, contributing KRW 9 million (6M pension savings + 3M IRP) at the 13.2% rate yields approximately KRW 1.188 million in tax savings.

Key differences: (1) Pension savings allow free mid-term withdrawals, while IRP restricts withdrawals to legally specified reasons. (2) IRP limits risk assets (equity ETFs, etc.) to 70% of the portfolio, while pension savings allow 100% in risk assets. (3) ETF trading within IRP is only available through securities firm accounts, not bank or insurance IRP accounts.

Not all ETFs can be traded in Korean pension accounts. Only domestically listed (KRX) ETFs are eligible — overseas-listed ETFs such as U.S.-traded VOO or QQQ cannot be purchased directly. Instead, investors use Korea-listed ETFs that track foreign indices.

The IRP 70% risk asset limit is crucial: equity ETFs, foreign index ETFs, and leveraged/inverse ETFs are classified as risk assets. The remaining 30% must be allocated to safe assets such as bond ETFs, deposits, or principal-guaranteed products. Note that leveraged and inverse ETFs are prohibited even in pension savings accounts.

Commonly used ETF categories in pension accounts include: (1) Domestic equity ETFs — KODEX 200, TIGER 200 tracking the KOSPI index; (2) Foreign equity ETFs — TIGER US S&P500, KODEX US Nasdaq100, ACE US S&P500; (3) Bond ETFs — KODEX KTB 10Y, TIGER Short-term Government Bonds; (4) TDF ETFs — KODEX TDF2045 with automatic asset allocation adjustments toward retirement date; (5) Dividend ETFs — TIGER US Dividend Dow Jones, KODEX High Dividend for steady income generation.

Pension investing is inherently long-term (10+ years), so low fees and stable diversification are paramount. Here are recommended combinations by account type.

**Pension Savings Portfolio (100% risk assets allowed)**

- Aggressive: TIGER US S&P500 (50%) + KODEX US Nasdaq100 (30%) + TIGER US Dividend Dow Jones (20%)

- Balanced: TIGER US S&P500 (40%) + KODEX 200 (20%) + KODEX US Nasdaq100 (20%) + KODEX KTB 10Y (20%)

- Conservative: TIGER US S&P500 (30%) + KODEX 200 (20%) + KODEX KTB 10Y (30%) + TIGER Short-term Gov Bonds (20%)

**IRP Portfolio (70% risk asset limit)**

- Aggressive (70:30): TIGER US S&P500 (40%) + KODEX US Nasdaq100 (30%) | KODEX KTB 10Y (20%) + TIGER Short-term Gov Bonds (10%)

- Balanced (60:40): TIGER US S&P500 (35%) + KODEX 200 (25%) | KODEX KTB 10Y (25%) + TIGER Short-term Gov Bonds (15%)

- Conservative (50:50): TIGER US S&P500 (30%) + KODEX 200 (20%) | KODEX KTB 10Y (30%) + TIGER Short-term Gov Bonds (20%)

Total expense ratios (TER) significantly impact long-term returns in pension accounts. Even among ETFs tracking the same index, fees can differ — always compare before choosing.

Here are the essential strategies for pension account ETF investing.

**1. Maximize Tax Deduction Limits**: Contribute the full KRW 9 million annually (KRW 6M pension savings + KRW 3M IRP). The tax credit alone provides an effective guaranteed return of 13.2–16.5%.

**2. Dollar-Cost Average to Reduce Timing Risk**: Set up automatic monthly transfers to buy ETFs regularly. Contributing KRW 750,000 per month over 12 months is generally better than lump-sum investing at the start of the year.

**3. Annual Rebalancing**: Rebalance when asset weights deviate more than 5 percentage points from targets. Within pension accounts, capital gains taxes are deferred, so rebalancing incurs no immediate tax cost.

**4. Plan Your Withdrawal Strategy**: Pension withdrawals begin at age 55 with a pension income tax rate of 3.3–5.5%, far lower than the standard financial income tax rate of 15.4%. Receiving distributions over 10+ years further reduces the rate.

**5. Leverage ISA-to-Pension Transfers**: When an ISA (Individual Savings Account) matures, transferring funds to a pension account provides an additional tax credit of 10% of the transferred amount (up to KRW 3 million). This ISA-to-pension relay strategy maximizes tax efficiency.
