Benefit
Based on earned income attributed to 2025 (withheld at source July 2026 - June 2027, or paid in advance by end of June): 20% of the portion exceeding an income amount of KRW 18,980,000 (gross salary KRW 28,510,000) (25% for graduate school loans). Repayment is deferred if income is at or below the threshold. Deferral can be requested (online) in cases such as unemployment, parental leave or being enrolled in school.
Who is eligible
Holders of income-contingent student loans whose annual income exceeds the repayment threshold income.
When to apply
The National Tax Service sends notices every year in late April; advance payment by end of June; withholding from July to June of the following year.
How to apply
National Tax Service student loan repayment (icl.go.kr, Hometax), National Tax Service consultation 126.
Important notes
A deferral request must be made within the deadline; late payment incurs a surcharge. For amounts deferred during enrollment, check deadlines such as payment by Dec 31, 2030.
Note
For 2026 attribution (repayment in 2027), check the National Tax Service's final notice. The figure of KRW 30,370,000 in some sources is presumed to be a conversion from total salary and needs confirmation.
