As the Korean National Pension start age approaches, one question dominates: take it early at a discount, or wait for more?
1. What is it worth to me. The same contribution record pays 70% (five years early) or 136% (five years deferred) — 1.94 times. This one decision nearly doubles a lifetime pension.
2. What is the risk. While claiming early, monthly average income above the A value (₩3,193,511 in 2026) suspends payment for that period. Even an on-time pension is cut for the first five years if income exceeds ₩5.19M, and the dependants' supplement is not paid at all during that time.
3. So what do I do. If your income falls in the reduction band, deferring is the better side — the same five years earn 7.2% a year instead of being cut. And an early claim is not final: a suspension application exists under Article 66(1)2.
How big is the gap — 70% against 136%
The source expresses early claiming as a payment rate, not a discount. It prints a worked example for someone born in 1966, whose early-claim age is 59.
| Age at claim | 59 | 60 | 61 | 62 | 63 |
|---|---|---|---|---|---|
| Payment rate | 70% | 76% | 82% | 88% | 94% |
Six percentage points a year. Five years early leaves 70% — a 30% cut, permanently. On the other side, deferral adds 7.2% for each deferred year (0.6% a month) under Article 62, so five years reaches 136%.
The same person with the same record can receive 70% or 136% — a factor of 1.94 (our calculation). This single decision comes close to doubling a lifetime pension. Compare your own figures in the national pension calculator.
From what age can I claim early
In the source's table (Act No. 8541, Supplementary Provision 8), the early age is exactly five years ahead of the normal one.
| Born | Old-age pension | Early old-age pension |
|---|---|---|
| 1953–1956 | 61 | 56 |
| 1957–1960 | 62 | 57 |
| 1961–1964 | 63 | 58 |
| 1965–1968 | 64 | 59 |
| 1969 or later | 65 | 60 |
“You can claim early from 60” is only true for those born from 1969. The full structure is in our National Pension guide.
Is an on-time pension safe from cuts
Focusing on early-versus-deferred hides a separate provision: reduction for work income (Article 63-2).
Even claiming on time, for the first five years your pension is reduced if your income is high.
The threshold is average monthly income at or above “the A value + 2 million won” — ₩5.19 million in 2026.
Check: 3,193,511 + 2,000,000 = ₩5,193,511, matching the source's “5.19 million.”
The dependant supplement is not paid at all during those years.
| Income above the A value | Reduction (source) | Monthly reduction | Monthly salary, if wages only |
|---|---|---|---|
| ₩2m to under ₩3m | ₩150,000 + 15% of the excess over ₩2m | ₩150,000–300,000 | ₩6,322,117 or more |
| ₩3m to under ₩4m | ₩300,000 + 20% of the excess over ₩3m | ₩300,000–500,000 | ₩7,374,749 or more |
| ₩4m or more | ₩500,000 + 25% of the excess over ₩4m | ₩500,000+ | ₩8,424,502 or more |
We divided the source's annual salary thresholds by twelve — 75,865,403 ÷ 12 = 6,322,116.9 → 6,322,117. All three round upward, consistently, matching the printed figures.
- The reduction is capped at half the old-age pension. However high the income, no more than 50% is lost.
- Income less than ₩2 million above the A value is excluded entirely (from 2025 income). ₩5.19 million is the real threshold.
- It ends after five years. The source: stopping work within five years of reaching the start age restores the unreduced pension.
Which points to a conclusion: anyone who would land in the reduction band is usually better off deferring. The five years that would be cut instead earn 7.2% a year. How gross pay becomes net is in our net pay table.
Do I have to defer all of it
- Available from acquiring the right until five years past the start age (five years maximum)
- Choose 50, 60, 70, 80, 90% or the whole amount — draw some for living costs and defer the rest
- The gain is calculated on the original pre-deferral amount, excluding the dependant supplement
- “Where deferral is applied for more than once, the increase from a previous deferral is not paid during a deferral period” — splitting it into several applications suspends the earlier gain
- “An increase from deferral may affect pension income tax, health insurance contributions and the basic pension” — the source warns of this directly
When does claiming early make sense
- You need the money now. The most realistic reason — if the alternative is borrowing or selling assets, the reduction may be worth it.
- Poor health or a shorter expected lifespan.
- Bridging a gap after leaving work — the interaction with unemployment benefit is in our unemployment benefit calculator.
The real trap in early claiming is “gainful work.” The source: “because the early old-age pension is paid ahead of the normal one on the premise that there is no income,” payment is suspended for any period with income. And the bar is average monthly income above the A value — ₩3,193,511 in 2026, far below the ₩5.19 million reduction threshold.
Is an early claim final
This is the part this article previously got wrong. The scheme rests on Article 66(1)2.
- Who: someone drawing an early old-age pension, below the normal start age, not engaged in gainful work
- Suspending makes you an insured member again, so you can pay contributions
- When payment restarts, the added insured months are included in a recalculated amount
The source does not say the reduction rate itself reverts. It goes as far as a recalculation reflecting longer coverage, and this article says no more than that.
Questions that remain
How long must I live for deferral to pay off?
This article no longer gives a break-even age. It used to say “early to mid-eighties,” but no such figure appears in the source and the calculation ignored indexation, tax and health insurance. What is certain is the rate — 70% against 136%, a factor of 1.94.
Do I pay more contributions while deferring?
No — deferral only moves the start date. Ways to actually add to the pension are in six ways to increase your pension.
Does a larger pension affect anything else?
Yes. The source names three: pension income tax, health insurance contributions and the basic pension. It gives no figures, so neither does this article.
What if I work part-time while claiming early?
Average monthly income above the A value (₩3,193,511 in 2026) counts as “gainful work” and payment stops for that period. Below it, payment continues.
What happens to the dependant supplement?
It is not paid during the five reduction years, and it is excluded from the base used to calculate the deferral gain.

Where to check further
- The break-even age. “How long must I live for deferral to win” turns on indexation, tax and health insurance premiums, none of which the source covers — the National Pension Service helpline (1355) runs it against your own record.
- How much a larger pension moves health insurance premiums and the basic pension. The source says only that it “may affect” them — the National Health Insurance Service (1577-1000) and the welfare helpline (129) can check your own case.
- Age-based reduction rates for those who acquired the right before 29 July 2015. The source gives only “differentiated by year, 50% to 10%” — a local Service branch can supply the figure for your acquisition date.
As of July 2026. The rates, thresholds and age tables are the National Pension Service's own; the ratios, conversions and checks are our arithmetic. Actual amounts and whether a reduction or suspension applies depend on your income and record — the Service's helpline (1355) is free.
