One of the most common questions from parents sending a child to a foreign school in Korea is "does this tuition qualify for the year-end education expense tax credit?" Many assume that because the school mainly serves foreign nationals, a Korean parent won't qualify. The real test isn't the student's nationality — it's which law the school is accredited under. That's why two schools that both call themselves a "foreign school" can land on opposite sides of the credit.

How the education expense credit is defined in the first place

Under Korea's Income Tax Act, the education expense tax credit only applies to tuition paid to schools accredited under the Early Childhood Education Act, the Elementary and Secondary Education Act, the Higher Education Act, or a special act. Money paid to an unaccredited institution doesn't qualify, no matter how real the enrollment and payments are. A "foreign school" here is classified as a miscellaneous school under Article 60-2 of the Elementary and Secondary Education Act — and whether it holds that formal accreditation is the first fork in the road.

The common misconception — nationality vs. accreditation

Parents often assume that because a school is attended mostly by foreign-national students, a Korean-national parent can't claim the credit. But the National Tax Service's actual criterion is whether the school itself is accredited, not what passport the student holds. If a foreign school is properly accredited, a Korean-national student attending it generally still meets the requirement for the school to be credit-eligible. Conversely, if the school isn't accredited, it doesn't matter that every student enrolled is a Korean national — the credit still doesn't apply.

Jeju's international schools are recognized under a separate special law

Schools established under the Act on the Establishment of Jeju Special Self-Governing Province and the Development of Free International City — namely KIS Jeju (Korea International School) and NLCS Jeju (North London Collegiate School Jeju) — are explicitly credit-eligible because they're established under that special law. Unlike ordinary foreign schools, their legal founding basis is different within Korea's school system, so there's no need to separately verify whether tuition there qualifies. That said, not every line item on a Jeju international school's tuition bill counts as "education expense" under the tax code — the same distinction that applies to any accredited school still applies here.

For an ordinary foreign school, accreditation comes first

For any foreign school other than the Jeju international schools, the first thing to check is whether it holds miscellaneous-school accreditation under the Elementary and Secondary Education Act. On top of that, Korean nationals face separate admission restrictions. Under the presidential decree governing the establishment and operation of foreign schools and foreign kindergartens, a Korean national generally can only enroll if they've lived abroad for a total of three years or more, and the school's principal determines the student would otherwise struggle to adjust due to limited Korean-language ability or cultural differences. Korean nationals also cannot exceed 30% of total enrollment — going over that is a violation. (Some local governments have recently pushed ordinances to relax that cap, so it's worth checking whether your school's local regulation has changed.) The most reliable way to confirm a school is maintaining valid accreditation while meeting these conditions is to ask the school directly before enrolling.

If overseas residency history is part of the picture

If a child has moved between a foreign school and schools abroad because of a parent's overseas assignment, that residency history can end up mattering for more than just the tax credit — it can also intersect later with the residency requirements for the special admissions track for Koreans living abroad (the 1,095 overlapping days of work, enrollment, and residence). The two systems are reviewed by completely different bodies with different requirements, but both share one thing in common: they both require documentation of exactly which school you attended during which period. Keeping tuition payment certificates and enrollment certificates organized by school year can save time on both fronts.

How to tell which line items on the bill actually qualify

Even at an accredited school, not everything on the tuition bill counts as credit-eligible education expense. The fact that international school costs go well beyond tuition applies just as much when you're calculating the tax credit. Items like tuition and admission fees are typically recognized as "education expense" under the tax code, while items like a school development fund, donations, bus fees, or meal fees often are not — and both categories frequently appear on the same bill. Some foreign schools in particular bill part of the cost as a "donation," which falls under the separate donation tax credit rules rather than the education expense credit.

What to actually gather at tax time

Korea's year-end settlement simplified-filing service automatically pulls payment records from most accredited domestic institutions, but foreign schools are frequently missing from that automatic lookup. In that case, you'll need to request a tuition payment certificate directly from the school and submit it to your employer. Asking the school's administrative office in advance about the certificate format and when it's issued can save you from scrambling during filing season. If you're preparing for a transition to a Korean university after graduating from an international school, organizing tuition documentation for your entire enrollment period now can also come in handy later during the academic-credential recognition process.

Putting it in order

First, confirm with the school whether it's accredited as a miscellaneous school under Article 60-2 of the Elementary and Secondary Education Act, or established under a special law like the Jeju international schools. Second, if your child is a Korean national, also confirm the three-year overseas residency requirement and the 30% enrollment cap. Third, on the tuition bill, separate credit-eligible items like tuition and admission fees from excluded items like donations or a school development fund. Fourth, request a tuition payment certificate from the school's administrative office ahead of year-end filing season to avoid gaps in the automatic lookup.
