Breaking a Korean private pension account early — either a yeongeum-jeochuk (pension savings account) or an IRP (Individual Retirement Pension) — triggers a flat 16.5% other-income tax on the contributions that earned a tax credit plus all investment gains accumulated inside the account. The rate does not vary with income. On the way in, the credit rate splits into two brackets, 16.5% or 13.2%, depending on salary. On the way out, everyone pays 16.5%. Anyone who earned above 55 million won and therefore received the 13.2% credit ends up returning more than they ever got.
There is one exception. If the withdrawal qualifies as an "unavoidable reason" under the Income Tax Act, the same money is taxed separately as pension income at 3.3% to 5.5%. What that fork is worth in actual won, and why a first-home purchase does not qualify for it, is the real variable behind the decision.
The bracket where you pay back more than you received
Two credit rates apply on the contribution side. According to Nongmin Shinmun, employment income up to 55 million won earns back as much as 16.5% at year-end settlement, while income above that ceiling earns up to 13.2%. Early termination, by contrast, applies 16.5% regardless of income level. The rate going in and the rate coming out simply do not match.
Put in numbers, the gap becomes concrete. Suppose someone contributed the full 6 million won annual credit ceiling for three years — 18 million won total — and the account grew 10%, adding 1.8 million won in gains. The taxable base on termination is the credited principal of 18 million plus the 1.8 million in gains, or 19.8 million won. At 16.5%, that is 3,267,000 won.
| Item | Salary up to 55M won | Salary above 55M won |
|---|---|---|
| Three-year contributions | 18,000,000 won | 18,000,000 won |
| Credit rate | 16.5% | 13.2% |
| Tax refunded over three years | 2,970,000 won | 2,376,000 won |
| Taxable base on termination | 19,800,000 won | 19,800,000 won |
| Other-income tax at 16.5% | 3,267,000 won | 3,267,000 won |
| Net result | -297,000 won | -891,000 won |
Strip the 10% gain out of the assumption and the lower bracket breaks exactly even (18 million × 16.5% = 2.97 million won), leaving only the upper bracket with a 594,000 won loss. Two things set the size of the damage: the 3.3 percentage-point rate gap created by the income bracket, and the size of the gains accumulated so far. The better the returns, the more expensive the exit — a genuine paradox of this account type. Contributions made beyond the credit ceiling never earned a credit in the first place, so they are not taxed on the way out.
The relationship between annual contributions and the credit ceiling is worked through in a separate calculation of the yeongeum-jeochuk and IRP credit limits.
Tax relief inside a pension account is deferral, not exemption. The moment the account breaks, the deferred amount comes due all at once.
Qualify as "unavoidable" and the rate falls by two thirds
The Financial Supervisory Service's consumer tips advise savers to check first whether the reason for withdrawal counts as an "unavoidable withdrawal" under tax law. An ordinary early withdrawal carries 16.5% other-income tax; a recognized unavoidable withdrawal is taxed separately as pension income at 3.3% to 5.5%.
The qualifying list is narrow and specific. As Mirae Asset Securities' IRP guide sets out, it covers natural disaster, death or emigration of the account holder, three months or more of medical care for the holder or a dependent, bankruptcy or personal rehabilitation proceedings, and suspension, license revocation, dissolution or bankruptcy of the financial institution holding the account. A procedural condition attaches as well: supporting documents must be filed within six months of the date the reason is confirmed. A valid reason filed late is taxed like any ordinary termination.
The applicable rate depends on the holder's age at withdrawal. Applying the same 19.8 million won base gives the following.
| Withdrawal type | Rate | Tax (won) | Saved vs. ordinary termination |
|---|---|---|---|
| Ordinary early termination | 16.5% | 3,267,000 | - |
| Unavoidable reason (age 55-69) | 5.5% | 1,089,000 | 2,178,000 |
| Unavoidable reason (age 70-79) | 4.4% | 871,200 | 2,395,800 |
| Unavoidable reason (age 80+) | 3.3% | 653,400 | 2,613,600 |
The same money withdrawn at the same time, and a single piece of paperwork moves the bill by more than two million won. In the 55-and-over band, 2,178,000 won equals 11% of the taxable base. Savers who simply click through the termination flow without checking are where much of the real loss happens.
Why a home purchase does not get the lower rate
This is where the most common misunderstanding arises. The Employee Retirement Benefit Security Act lists buying a home or funding a jeonse (lump-sum deposit lease) as a permitted ground for IRP early withdrawal. The withdrawal itself goes through. But the Income Tax Act's list of unavoidable reasons contains no housing item at all. The money comes out, and it is taxed at the same 16.5% as any other termination.
The gap exists because permission to withdraw and eligibility for the preferential rate sit in two different statutes. Hearing "yes, you can withdraw" at a bank counter does not confirm the tax treatment. The two questions have to be asked separately: can the money come out, and at which rate.
Severance money parked in an IRP follows yet another track. Retirement-benefit funds are taxed under the retirement income regime rather than as other income, and taking them as an annuity applies 70% of the retirement income tax rate (60% from the eleventh year of payments). Taking a lump sum forfeits that reduction. Reading it alongside how years of service drive retirement income tax makes the comparison easier to judge.
What to check before hitting terminate
Pension accounts have a withdrawal order fixed in law. As Hankyung explains, money contributed without claiming a tax credit is paid out first, and that money is not taxed at all. Transferred severance funds come next, and credited contributions plus investment gains come last. Anyone who contributed above the credit ceiling can therefore pull that portion out tax-free.
- Check the excess-contribution balance — any amount contributed above the 6 million won ceiling (9 million including IRP) comes out untaxed
- Test the unavoidable-reason list — medical care must run three months or longer, and documents are due within six months of the confirming date
- Partial withdrawal instead of full termination — taking only what is needed keeps the rest tax-deferred
- Consider pausing contributions — holding the account open while stopping payments triggers no tax at all
- Compare a pension-account secured loan — check whether the loan rate sits below the effective tax burden before deciding
- Count the years to age 55 — the closer the annuity start date, the higher the opportunity cost of terminating
