Which Korean Social Insurances You Are Actually In

Two people do the same job at the same company for the same salary. Their payslips show different deductions. Both are correct.

That is not an anomaly in Korean payroll — it is the predictable result of four social insurances that each decide who is covered by a different test, only one of which works the way people expect nationality to work.

Establish enrolment before you argue about an amount.

National pension: three things at once

Being foreign neither guarantees coverage nor exempts you from it. The question runs on:

So a missing pension line on a foreign employee’s payslip is not evidence of an error. It is a prompt to check which of the three applies — and to make sure one of them actually does.

The refund is not a consequence of having paid

This is the single most consequential misunderstanding for anyone whose Korean stay is finite.

Contributions do not convert into a departure payment because they exist. A lump-sum refund requires one of three routes: your country pays equivalent benefits to Korean nationals, a social security agreement provides for the refund, or your status of stay is one the law specifies.

Across the two nationality routes the qualifying list currently runs to around fifty countries, split between agreement and reciprocity.

Health insurance does not follow the pension’s logic

Workplace health insurance is judged on the employment relationship meeting the statutory conditions — not on nationality reciprocity or a social security agreement in the way the pension is.

The employer must report the acquisition of subscriber status within 14 days of the day it begins.

Which produces the combination that confuses new arrivals most: no national pension line, and full health and long-term care lines, on the same payslip, correctly. Two statutes, two tests, two answers about the same person.

Family are not covered on arrival

Becoming a workplace subscriber does not sweep arriving family into the scheme.

Dependant status has relationship, income and property conditions, and for foreign nationals and overseas Koreans a six-month residence requirement applies in certain cases. How it lands varies with the relationship and the family member’s own residence status, so a spouse and a minor child are worth checking individually rather than assumed in either direction.

The exposure is the gap. A hospital visit before registration completes is billed at the uninsured rate, and Korean hospital pricing without insurance is not a rounding difference — what that looks like is in NHIS health insurance for foreigners.

Employment insurance: the table everyone gets wrong

Coverage is not uniform across foreign employees, and the shape of the rule is not “some visas in, some visas out”.

Being insured and being able to claim are different

Job-seeking benefit requires at least 180 insured days within the 18 months before leaving — and insured days are not calendar days of employment. They count days that were the basis for remuneration plus paid weekly holidays, and exclude unpaid days. A part-time or irregular schedule can therefore fall short after well over six months on the payroll.

The statutory conditions on the reason for leaving and on active job-seeking apply as well. And for a foreign claimant there is a second gate that is not in the Employment Insurance Act at all:

Employment insurance is also not only unemployment — parental leave benefit and maternity-related benefits run through it — but the same status-dependent application question governs those.

Industrial accident does not ask

An employee injured at work is not outside industrial accident protection because of their status of stay. The scheme is judged on the workplace and the employment relationship.

Where a person’s stay is irregular, the compensation question and the immigration question are assessed separately rather than as one. “You are foreign, so there is no industrial accident cover” is not a statement of the law, and it is worth recognising as such at the moment it is said — which is usually the moment someone is hurt and least able to argue.

Three checks, in order

Reading these deductions properly is not adding up what left your salary. It is establishing why you are in each scheme, what base and rate were applied, and what each one would actually pay if the risk it insures arrived — and for a foreign employee, whether the payroll team was ever told the status that decides it.
