Do I need to pay Korean pension if my contract is under three months?
Short answer: contract length by itself isn't the test. National Pension enrollment turns on your hours, how the contract is written, and your nationality, not on whether the paper says "three months."

If you've heard "under three months, no pension," you're thinking of the wrong rule. That three-month line comes from Korea's notice-period law, not the pension one. The relevant statutory anchor is LSA Article 26: employers are exempt from the 30-day termination-notice requirement only for an employee with less than three months of continuous service. That's about getting fired without notice. It has nothing to do with the National Pension Service (NPS).
What actually decides your pension enrollment
The NPS looks at how the job is structured, not the headline length of the contract. Per NPS's own guidance on workplace enrollment, the real exclusions are:
Daily workers or workers employed for a fixed term of less than one month are excluded, unless they work 8 or more days a month, 60 or more hours a month, or earn above a threshold set by the Ministry of Health and Welfare. Separately, part-time workers whose monthly working hours fall below 60 hours (an average of 15 hours a week) are also excluded, unless they're lecturers continuing for three or more months or opt in with their employer's agreement.
Notice what that means in practice: a full-time hagwon hire teaching 30+ hours a week on a two-month contract clears both thresholds easily. You're over 8 days a month, over 60 hours a month, and not a casual daily hire. That means enrollment, not exemption, is the default outcome, even with a short contract.
| Your situation | Likely pension outcome |
|---|---|
| Full-time hagwon job, contract under 1 month | Usually excluded, unless you hit 8+ days or 60+ hours that month |
| Full-time hagwon job, 1 to 3 month contract, 30+ hours a week | Enrollment required |
| Genuinely part-time, under 15 hours a week | Excluded, unless you opt in after 3 months with employer agreement |
| Your nationality is on NPS's reciprocity exclusion list | Excluded regardless of contract length |
Where nationality comes in
Even with hours and contract length sorted, your passport matters. Korea applies National Pension to foreign workers on a reciprocal basis: your home country has to offer something comparable to Korean nationals for you to be required to pay in. This is also why Americans sometimes expect a US-Korea agreement to exempt them from Korean pension the way it can with Social Security tax at home. It doesn't, for hagwon work specifically. The Agreement does not cover civil servants, military personnel, or private school teachers. So a hagwon teacher from the US still pays in like anyone else, and gets it back as a lump sum later. Foreign nationals from countries that have reciprocity agreements with Korea, including the United States, Canada and Australia, may apply for a lump-sum refund when permanently leaving Korea.
What to actually do with a short contract
- Ask whether the contract is being filed with NPS as a fixed-term hire under one month, or as a standard employment contract. The wording changes your status.
- Check your first payslip for a 4.5% pension line. If your hours are full-time and it's missing, ask why, in writing.
- Keep a copy of your enrollment confirmation (가입증명서) if NPS gives you one. You'll want it later when you apply for the lump-sum refund.
One thing we'll admit varies: the reciprocity list isn't something you can eyeball from a blog post, and we won
