💡 Claiming the pension tax deduction as a self-employed person takes about 30 minutes if you know exactly which steps to follow — here’s the full process from account setup to confirmed refund.
Why Self-Employed Individuals Often Miss This Deduction Entirely
Salaried workers have it easy. Their year-end tax settlement (yeongmal jeongsan) is handled mostly through their employer’s HR process. They submit a few documents, and the math gets done for them.
If you run your own business or work as a freelancer? You’re doing this yourself. And that’s exactly why so many self-employed individuals between 30 and 50 leave the pension tax deduction unclaimed year after year — not because they don’t qualify, but because the process feels like a maze the first time you try to navigate it.
I talked to someone I know who runs a small consulting practice. Sharp person, excellent with money — but she had never opened an IRP account because she assumed it was “only for office workers.” She was three years into running her business before someone corrected her. Three years of missed deductions.
Don’t be that person.

Step 1 — Open or Confirm Your IRP Account
Before anything else, you need a qualifying account. The two main options are:
- Pension savings account (yeongeumjeochuk) — available at banks, securities firms, and insurance companies
- IRP (Individual Retirement Plan / Gaein hyeoptong toejigeumje) — available at most financial institutions
As a self-employed individual, you’re eligible for both. The IRP in particular has no employer requirement — you open it yourself, contribute yourself, and claim the deduction yourself.
Opening one takes about 20 minutes online. Most major banks and securities firms (including Mirae Asset, Samsung Securities, KB, and Shinhan) offer the process entirely through their apps. You’ll need your national ID number and basic income documentation.
One thing worth knowing: if you already have an IRP from a previous employer that you rolled contributions into, check whether it’s still “active” for new contributions. Dormant accounts sometimes need to be reactivated before new contributions count for the current tax year.
Step 2 — Make Your Contribution Before the Deadline
Here’s where the tax-saving strategy gets real.
The contribution deadline for the current tax year’s deduction is December 31st. Not the filing date — the actual end of the calendar year. Contributions made in January 2025 count toward your 2025 taxes, not 2024.
So how much should you contribute? Let’s run the numbers.
Contributing the full 5 million KRW gives you the maximum deduction available under the pension savings account cap. If you have an IRP as well, you can go up to a combined 9 million KRW — though the pension savings portion is still capped at 5M (or 6M if you’re 50 or older).
Honestly, I was skeptical the first time I calculated this. It felt too straightforward. But the math checks out — and unlike most “tax strategies” you hear about, this one requires zero complicated structuring.
Step 3 — Submit Your Deduction Application
After contributing, you need to collect your contribution certificate (, napip hwagin-seo) from your financial institution. This is usually available as a PDF download directly from your bank or securities app, typically in January for the prior year’s contributions.
From there, the submission process depends on your filing method:
- Hometax ( — use “Hometax” in English): Log in at the National Tax Service portal, navigate to the income deduction section, and upload your contribution certificate.
- Local tax office: Bring printed copies of your contribution certificate and ID. Staff can walk you through the form.
- Through a tax accountant (sejumsa): If you already use one for your business filings, hand them the certificate and let them handle it.
The filing window for individual income tax (jonghabsodeuk jeongsansin-go) runs from May 1 to May 31 for the prior year. Mark it in your calendar now — it’s easy to miss if your business has you busy in spring.
Step 4 — Verify the Deduction on Your Tax Return
After submitting, you’ll want to confirm the deduction actually appears. On Hometax, you can check your submitted return and see the line item for pension savings deductions.
Am I the only one who finds this verification step genuinely satisfying? There’s something about seeing a 600,000 to 750,000 KRW credit line appear on an official tax document that makes the whole process feel worth it.
If the deduction doesn’t show up — and this does happen occasionally when account numbers or contribution dates have errors — contact your financial institution first, not the tax office. Most issues trace back to how the contribution was reported by the institution, not how you filed.

"1M KRW contributed → 150K saved" : 150
"3M KRW contributed → 450K saved" : 450
"5M KRW contributed → 750K saved" : 750
The entire process — account setup, contribution, filing, and verification — is something most people can complete in under two hours total, spread across the year. For 600,000 to 750,000 KRW back in your hands, that’s an exceptional return on your time.
