Money put into pension savings and IRP qualifies for a tax credit on up to KRW 9 million per year. If your total salary is KRW 55 million or less, 16.5% of your contribution comes back in the year-end tax settlement; above that, 13.2%.
Employees enter their total salary; those with business or other income enter their comprehensive income amount. This determines your credit rate.
Enter what you have contributed or will contribute this year to pension savings and IRP, plus any ISA maturity transfer.
Check the remaining room under the limit and the monthly amount to split it into, and finish contributing before the last business day of December.
Tax credit for a salaried worker's own contributions to a pension savings account and an IRP, assuming enough tax is owed to use the full credit. Amounts are in Korean won.
US dollar figures are rough conversions at an illustrative rate of 1,400 won per dollar and are not live exchange rates. If the tax owed is lower than the credit, the refund stops at the tax owed.
Contributions qualify for the credit up to ₩6 million a year for pension savings and ₩9 million combined with an IRP. The credit rate is 16.5% for gross salary up to ₩55 million (comprehensive income up to ₩45 million) and 13.2% above that, both including local tax, for a maximum credit of ₩1.485 million or ₩1.188 million. Reference date: tax year 2026, checked October 3, 2026.
Only up to KRW 6 million of pension savings is eligible for the credit. To get the full KRW 9 million credit, you must put at least the remaining KRW 3 million into an IRP. Filling KRW 9 million with an IRP alone is possible.
The credit rate drops from 16.5% to 13.2%, a decrease of 3.3%p. If you contributed the full KRW 9 million, the maximum refund falls from KRW 1,485,000 to KRW 1,188,000. The threshold is based on total salary after excluding non-taxable allowances, not your annual salary.
No. The pension account tax credit applies only to amounts you paid yourself into accounts in your own name. Each spouse must fill the limit with their own account.
A tax credit is subtracted from determined tax, so if you owe no tax there is nothing to get back. In that case, contributions that did not receive a credit are excluded from taxation when you later receive them as a pension.
Yes. The credit is based on the total contributed over the year, so putting it in at once in December gives the same result. However, transfers pile up at year-end, so it is safer to deposit a few days before the deadline.
It applies in the year you move ISA maturity funds into a pension account within 60 days of maturity. 10% of the transferred amount, up to KRW 3 million, is added to the eligible base on top of the existing KRW 9 million limit.
