Korea's Pension Savings and IRP Tax Credit 2026: Contribute by December 31, Up to 9 Million Won, and Three Things to Check First
As the year winds down, a familiar question comes up among people who pay income tax in Korea: should I top up my pension savings account before December, and how much would I get back if I filled my IRP to the limit? The pension account tax credit is calculated on what you pay in between January 1 and December 31, so contributions for this year's credit have to land before the year ends.
There is a catch built into the deal, though. This money is, in principle, meant to be drawn as a pension from age 55. You get tax back in exchange for locking the money away for a long time. Before you aim for the maximum, decide how much you can actually afford to leave untouched.
Everything below was checked on October 12, 2026 against official guidance from the National Tax Service and the Financial Supervisory Service. It covers the limits, the credit rates and what you get back, how a pension savings account differs from an IRP, and three things to check before paying in. This is not a recommendation for any particular product.
1. The limits: 6 million won for pension savings, 9 million won with an IRP
Two limits overlap.
In practice, that gives three combinations:
You can pay up to 18 million won a year into a pension savings account, but only the amounts within the limits above earn the credit. Anything beyond that does not reduce this year's tax.
The retirement pension side includes an IRP (individual retirement pension) that you open yourself, and extra contributions you make yourself to a company defined-contribution (DC) plan. The contributions your employer makes to a DC plan do not count.
Moving a matured ISA raises the limit. If your Individual Savings Account (ISA) matures and you move that money into a pension account in the same year, your credit limit rises by 10% of the amount moved, up to 3 million won. This applies only in the year of the transfer.
2. The credit rate: 55 million won in total salary is the dividing line
The rate depends on income. The figures below include local income tax, so they reflect what you actually get back.
If you fill the limit, the credit works out as follows:
One point to keep in mind: a tax credit reduces the tax you owe. If your tax bill is small to begin with, you may not get back the full amount calculated above, so it is worth estimating this year's tax before deciding how much to contribute.
3. How a pension savings account differs from an IRP
Both earn the credit and both are designed to be drawn as a pension from 55. The biggest practical difference is whether you can take money out along the way.
An IRP generally does not allow partial withdrawals. Because it is a retirement pension account, money can come out early only for reasons set by law:
With either account, taking credited money out other than as a pension costs you. Contributions that earned the credit, along with their investment returns, are taxed at 16.5% at source if withdrawn outside of pension payments.
So whether to stop at pension savings or fill an IRP as well comes down to whether this money can genuinely stay put until you are 55.
4. Three things to check before you pay in
One: at the 13.2% rate, withdrawing early leaves you worse off
If your credit rate is 13.2% and you later withdraw that money early, it is taxed at 16.5%. You pay back more than you received. Even at the 16.5% rate, the returns are taxed too, so there is little left to gain. Emergency funds and money you may need within a few years do not belong here.
Two: drawing it as a pension has conditions
To get the lower pension tax rates later, three conditions apply:
If your pension income from these accounts is 15 million won a year or less, you can choose between separate taxation at 3.3% to 5.5% and adding it to your other income. Above 15 million won, the choice is between 16.5% separate taxation and comprehensive taxation.
Three: what counts is money paid in by December 31
The credit is based on what actually reaches the account within the year. Financial institutions have their own cut-off times at year end, so paying in by mid-December is safer than leaving it to the last day. Money moved in from another pension account, and untaxed money such as a retirement payout that has not yet been taxed, does not count as a contribution.
Summary
The credit is a real benefit, and its price is time. The goal is not to hit the limit. It is to decide how much you can lock away, and then claim the credit on that amount.
