💡 Pension savings and IRP aren’t competing options — they stack, and knowing which to fill first can meaningfully change how much you get back at tax time.
Two Accounts, One Ceiling — Here’s How the Stack Works
Here’s something that confused me for longer than I’d like to admit: a pension savings account and an IRP don’t have two separate caps. They share one.
The pension savings account allows a tax deduction of up to 6 million KRW per year. An IRP adds up to 3 million KRW more. Combined? 9 million KRW is the maximum deductible amount across both. For most people in their 30s earning under 55 million KRW, the deduction rate is 16.5% — meaning a fully maxed-out combined strategy delivers a refund of up to 1,485,000 KRW. Annually. Just from these two accounts.
Understanding this stack — and which account to fill first — is where a lot of people either win or quietly leave money on the table.

Liquidity — The Number That Changes Everything for Irregular Income
This is the part that matters most if your income varies month to month. And it’s also exactly the part that most financial product brochures gloss right over.
With a pension savings account, partial early withdrawal is allowed. The catch: the withdrawn portion gets taxed at 16.5% as “other income.” Not ideal — but in a cash crunch, it’s a real option. The rest of the account stays intact.
An IRP is stricter. Early withdrawal typically means closing the entire account (with narrow exceptions), and the amount withdrawn is taxed as miscellaneous income — potentially higher depending on your total earnings that year. For someone with variable freelance income, that unpredictability is a genuine risk, not just an abstract footnote.
A graphic designer I know — early 30s, runs her own studio — learned this lesson the hard way. She’d loaded up her IRP with two years of contributions, hit a slow quarter, and needed liquidity. The early exit cost her a meaningful chunk in taxes. Now she maxes her pension savings account to 6 million first, keeps IRP contributions modest and variable, and adjusts based on how the year is actually going. Much less stressful.
The point isn’t that IRPs are bad. It’s that they’re less forgiving. And for anyone whose income doesn’t arrive in a straight line every month, that flexibility gap has real financial value that the deduction numbers alone don’t show.
Which Account Wins Based on Your Situation
Short answer: pension savings first, IRP second. But the reasoning matters more than the order.
If your income is under 55 million KRW and you can only commit to one account right now, pension savings is the move. You get the larger deduction with a built-in escape valve if things get tight. The IRP’s additional 3 million deduction is worth pursuing — but only once your pension savings contributions are maxed.
Plot twist: for higher earners above 120 million KRW, the pension savings deduction cap actually shrinks to 3 million KRW. The IRP cap stays unchanged. At that income level, the IRP becomes proportionally more valuable — and the contribution priority can reasonably flip.
Running a Combined Strategy When Income Is Unpredictable
Here’s what actually works in practice for freelancers and self-employed professionals: anchor your pension savings contributions, treat IRP as a variable top-up.
Set a baseline monthly amount for your pension savings account — conservative enough that you can sustain it even in a slow month. Earlier this year I mapped this out across three income scenarios (strong year, average year, tough year), and the pattern held consistently: keeping the pension savings contribution steady and adjusting IRP contributions by quarter smoothed out the annual tax benefit without creating cash flow risk.
Strong quarter? Direct the surplus into your IRP. Lean month? Skip the IRP contribution entirely — your pension savings deduction is still secured. You don’t lose anything by pausing IRP contributions mid-year.

Am I the only one who finds the official product descriptions for these two accounts unnecessarily opaque? Every provider seems to market them as completely separate products. They’re not — and once you see them as a single stacking system with one shared ceiling, the whole contribution strategy gets a lot cleaner.
One last thing, especially for the self-employed: national pension contributions you pay yourself are deducted separately under social insurance — they don’t count toward the pension savings deduction limit. Don’t accidentally fold them into your mental accounting. It’s an easy mistake to make, and I’ve seen it throw off someone’s entire year-end tax calculation badly enough that they over-contributed to their pension savings account chasing a cap they’d already hit.
