You hoped for a year-end tax refund — "the 13th paycheck" — but ended up owing instead. If that sounds familiar, the surest way to flip the outcome in Korea is pension savings and an IRP.
In short: contribute ₩9M a year combined to pension savings and an IRP, and depending on income you get back up to ₩1,485,000 (16.5%) straight off your tax. It's essentially the only item where you get a refund just for saving, not spending.
Why you get money back — a tax credit
This isn't a deduction that merely lowers your income — it's a tax credit taken directly off the tax you owe, so the effect is bigger. On top of that, gains inside the account aren't taxed now (tax deferral), and when received as a pension later they're taxed at a low rate (5.5% or less) — a double, triple benefit.
Limits and credit rate
Credit limit: ₩6M for pension savings + up to ₩9M combined with an IRP.
Rate: gross salary ₩55M or less (comprehensive income ₩45M or less) → 16.5%; above that → 13.2%.
Max out ₩9M and the lower-income side gets ₩1,485,000 back, the higher-income side ₩1,188,000. A ₩750,000 monthly auto-transfer adds up to exactly ₩9M.
Pension savings first, IRP second
Pension savings alone caps the credit at ₩6M, so the common approach is to fill ₩6M in pension savings, then ₩3M in an IRP. Pension savings allow slightly more flexible early withdrawal than an IRP.
Key cautions
- Deposit by December 31 to count for that year (a year-end lump sum is fine; for pension-savings funds, allow a few days since the trade date counts).
- Close it before age 55 and a 16.5% "other income" tax hits the credits and gains — effectively clawing back what you received. Treat this as money you leave until retirement.
Pension savings vs. IRP — the differences
| Tax credit limit | Pension savings ₩6M / ₩9M combined with IRP |
| Number of accounts | Pension savings: several / IRP: one per provider |
| Risk assets | Pension savings: no cap / IRP: up to 70% |
| Early withdrawal | Pension savings: possible (taxed) / IRP: restricted |
| Receiving severance | Pension savings: no / IRP: yes |
In short, pension savings are more flexible, while an IRP locks funds up but can hold your severance. The usual order is to fill the ₩6M pension savings limit first, then the remaining ₩3M in an IRP.
⚠️ Closing early costs more than you gained
Closing without a legally recognized reason triggers 16.5% other-income tax on the credited contributions and investment gains. You can end up paying back more than you received.
- Withdrawals as a pension start at age 55 — until then the money is locked.
- Never put emergency funds or money you'll need soon into these accounts.
- Forcing yourself to hit the limit and then closing early backfires. Contribute only spare funds.
FAQ
If I put all ₩9M into pension savings, is it all credited?
No. Pension savings alone caps at ₩6M. To get the other ₩3M credited, contribute it to an IRP.
Do the self-employed and freelancers qualify?
Yes — with income you qualify, applied at the May global income tax filing.
Pension-savings insurance or pension-savings fund?
The tax credit is identical. Want principal protection → insurance; want long-term growth → fund (ETFs, etc.). Choose by your risk appetite.
You prepare for retirement and get tax back at the same time. If you have spare money, fill the limit before year-end.
