Korea's Spousal Leave Rules Change on 18 September — What Payroll Has to Do Before Then

On 18 September 2026 three amendments to Korea’s Equal Employment Opportunity and Work-Family Balance Assistance Act commence at once, and a fourth already commenced on 20 August. Two of them change dates your payroll calendar depends on. One creates an entitlement that did not exist in Korean law before. None of them is optional, and the first employee to invoke any of them will do so with less notice than you would like.

The package matters more to a small foreign-owned entity than its size suggests. A twenty-person subsidiary with two expectant fathers is now exposed to leave patterns it has never planned around, and the reimbursement that offsets the cost is available only to employers who fall inside a definition most of them have never checked.

What actually changes on 18 September

The Ministry of Employment and Labor set out the detail when the Cabinet approved the two enforcement decrees on 11 August. Four items, three dates:

The fourth row is already live. If nobody in your Korean office has mentioned it, that is not evidence it has not been used — the benefit is claimed from the government, not from you, and the first you may hear of it is a week’s absence.

The spousal leave window moved backwards, not forwards

This is the change most likely to surprise a payroll administrator, because nothing about the entitlement itself moved.

Article 18-2 of the Equal Employment Act gives an employee whose spouse gives birth 20 days of leave, in full pay, splittable into up to three periods. That has been the position since the 2024 amendment and it is not changing. What changes is when the clock starts. Today the leave cannot begin until the child is born, and Article 18-2(3) closes the window 120 days after the birth. From 18 September the window opens 50 days before the expected date of delivery and still closes 120 days after the birth — a usable period of roughly six months rather than four.

The ministry also renamed it. 배우자 출산휴가 becomes 배우자 출산전후휴가 — spousal pre- and post-natal leave — and the Employment Insurance Act was amended in the same package to carry the new name through to the benefit provisions.

One feature is easy to misread if you are used to leave systems elsewhere. This is not an application the employer approves. Article 18-2(1) says the employer must grant the 20 days where the employee notifies it, and the enforcement decree specifies that the notification is a document stating the expected or actual date of birth and the days the employee intends to take. There is no discretion to refuse, and Article 18-2(5) separately prohibits dismissal or any disadvantageous treatment for taking it.

The entitlement that did not exist before

Article 18-4 is new. Where an employee’s spouse suffers a miscarriage or stillbirth, he may take up to five days of leave, of which the first three are paid.

There was no equivalent before. An employee in that position took annual leave, or unpaid leave, or nothing. So this is not a widening of an existing line in your leave register — it is a new row, and if your HR system enumerates leave types in a dropdown, someone has to add it.

The cost sits differently from most Korean statutory leave, and the split is worth understanding before your first case:

Where the workplace qualifies, the benefit is 100% of ordinary wages, subject to caps the ministry published alongside the decree: 84,210 won for one day, 168,420 won for two, 252,630 won for three. An employee whose daily ordinary wage exceeds 84,210 won — which at a monthly salary above roughly 2.5 million won it will — costs the employer the difference. That is a small number. The point of knowing it is that it is not zero, and it is not claimable at all by an employer outside the definition.

Whether you get reimbursed turns on a definition you have probably never checked

The Employment Insurance Act provision that funds the new leave, Article 76(1)4, is expressly limited to workplaces that are priority support enterprises (우선지원대상기업). The same limitation governs reimbursement of spousal birth leave. If you have been assuming the government pays for spousal leave, that assumption is conditional.

Article 12 of the Enforcement Decree of the Employment Insurance Act sets the test, and three features of it matter to a foreign-owned company:

It measures your Korean entity, not your group. Paragraph 5 counts the employees regularly used across all businesses of that employer. The employer is the Korean legal person that holds the employment insurance relationship. A subsidiary of a global parent with 40,000 staff is assessed on its Korean headcount against the industry thresholds in Table 1 to the decree. This is the opposite of the intuition most head offices arrive with.

The arithmetic is an average, and part-timers are discounted. You sum the headcount at each month-end across the previous year and divide by the number of months the business operated. A part-timer working 60 or more hours a month counts as half a person; one working under 60 hours is left out of the count entirely. Where a business’s insurance relationship was established during the year, paragraph 6 tests it as at the establishment date instead.

Falling out of the definition is gradual, but one exclusion is immediate. Paragraph 3 gives a company that grows past the threshold five further years of priority support treatment. Paragraph 4 has no such grace: a company in a cross-shareholding business group designated under the Monopoly Regulation and Fair Trade Act stops being a priority support enterprise from the insurance year after designation. Foreign-owned entities are generally not in those groups, which is a quiet advantage.

Childcare leave before the child arrives

The third September change is narrower and easier to administer wrongly. Until now a male employee could only take childcare leave after his child was born. From 18 September, where his pregnant spouse faces a health risk such as threatened miscarriage or premature birth, he may take childcare leave before the birth in order to care for her. The application must reach the employer at least seven days before the intended start date.

The government’s summary makes the point that using it this way does not consume one of the permitted splits of childcare leave — the period is taken without decrementing the split count. That is a deliberate design choice and it means an employee who uses leave during the pregnancy has not spent an option he will want later.

The change that already happened

Short-term childcare leave commenced on 20 August 2026, so it is live now.

An employee raising a child may take one or two weeks of childcare leave, once per year, where the child needs concentrated care — a nursery or school closure, a vacation period, or hospitalisation following illness or an accident. The days count against the maximum childcare leave period of 1.5 years but, again, not against the number of permitted splits. Childcare leave benefit is payable for the period.

The notice requirement is split by reason, and this is the operationally significant part: leave taken for a school vacation must be applied for 30 days in advance, but leave for a closure, illness or accident-related hospitalisation may be applied for to start the same day. A finance manager who expects 30 days’ notice for all absences has misread the rule in the direction that will cause the problem.

What this actually costs you

Less than the administrative noise suggests, provided the mechanics are set up.

The 20 days of spousal leave were already paid and already reimbursable. The new miscarriage leave adds at most three paid days per affected employee, largely reimbursed. Short-term childcare leave is unpaid by you and funded by employment insurance. The genuine cost is coverage — an unplanned two-week absence in a five-person finance team is a real problem, and the notice rules now permit it to arrive on the day.

What creates avoidable cost is the paperwork trail. A leave granted under the wrong code does not get reimbursed. A benefit claim filed after its deadline does not get paid. A handbook that contradicts the statute is the first document a labour inspector reads, and it is read alongside the four major insurances records that fund the leave in the first place. Our payroll outsourcing service carries these commencement dates on the compliance calendar precisely because they arrive in clusters like this one and none of them announces itself.

The honest limit: if you have three employees in Korea and none is likely to become a parent this year, nothing here needs to happen this month. Note the dates, and deal with them when the leave register is next opened. What you should not do is leave a filed Korean handbook asserting a rule that stops being true on 18 September, because that costs nothing to fix now and is awkward to explain later.
