Two families pay the same academy fees, yet only one gets money back at tax time. The difference comes down to a single line: whether the child has started elementary school yet. Under Article 59-4 of Korea's Income Tax Act, the education expense tax credit splits its eligible items and caps by the dependent's status, and missing the exact boundary means quietly losing a 15% credit every year. Here is where the line falls, from university tuition down to preschool academy fees.

The credit rate is 15%, but the cap depends on who you're claiming for

The education expense tax credit isn't a deduction that lowers taxable income — it's a credit that subtracts 15% of what you spent directly from your calculated tax. The catch is that the spending ceiling this 15% applies to comes in three tiers depending on the dependent's status. Preschool children and elementary-through-high-school students are capped at 3 million won a year, a university-age child at 9 million won a year, and the wage earner's own education expenses have no cap at all. Even within the same 3-million-won tier, what counts as eligible spending is different for a kindergartener than for a high schooler — and that's where most people trip up.

Academy fees count only before elementary school — not after

This is the part parents miss most often. Tuition paid to an academy registered under the Act on the Establishment and Operation of Private Teaching Institutes and Extracurricular Lessons — for a course run at least once a week on a monthly basis — is eligible for the credit only for a child who has not yet started elementary school. The moment that child enrolls in Grade 1, the same academy and the same class stop qualifying. Korea's National Tax Service defines the eligible group explicitly as "children before elementary school entry," which is exactly why an English-academy or arts-academy bill for a first grader cannot be filed under a child's education expenses.

9 million won for a university-age child, 3 million for K-12

Because tuition bills are largest at university, that tier also carries the widest cap. University tuition qualifies for the 15% credit up to 9 million won a year, while a K-12 child's tuition, admission fees, school-meal costs, textbook costs, and after-school program fees (including books) are capped at a combined 3 million won a year. Households raising more than one child should also remember that the cap applies separately to each child — a university-age child and a high-schooler can each fill their own 9-million-won and 3-million-won ceilings independently, and this runs separately from income-tested education support programs such as therapy-service vouchers for students with special needs, so the two shouldn't be confused.

Why the wage earner's own education expenses have no cap

Unlike dependents, a wage earner's own education expenses carry no ceiling at all. Graduate school tuition, part-time university tuition, and vocational training institute fees all qualify — and so does principal and interest repaid on a student loan. Plenty of early-career workers paying down an income-contingent student loan don't realize that the amount withheld from their pay each month also qualifies for the 15% credit. It's still worth double-checking on Hometax before filing that the repayment isn't already claimed under a different income deduction or credit.

What happens the year a preschooler becomes an elementary student

This question comes up often for families whose child starts elementary school partway through the year. The answer: only spending before enrollment counts. For a child entering Grade 1 in March, academy fees paid in January and February — while the child was still technically preschool-age — remain eligible, but fees paid after enrollment do not, even at the same academy. This is exactly why year-end tax paperwork should be split by the enrollment month rather than filed as one lump sum for the year.

Paying academy fees by credit card can qualify for two credits at once

If a preschooler's academy fees are paid by credit card, the household can claim both the credit card spending deduction and the education expense tax credit on the same payment. The card spending goes toward the credit-card usage deduction, while the identical expense is separately claimed under the education expense credit. This overlap, however, applies only to academy fees — kindergarten and daycare tuition qualify for the education expense credit alone and are excluded from the credit-card deduction. Filing academy fees and kindergarten or daycare tuition under the same receipt category is a common way this calculation goes wrong.

Preschool academy fees don't show up automatically in the simplified service

Plenty of parents open Hometax's simplified year-end tax service, see nothing listed under academy fees, and give up on the credit entirely. A preschooler's academy fees are not an item that appears automatically in the Hometax simplified service. You have to request a tuition payment certificate directly from the academy and submit it separately to your employer's payroll team. Unlike support programs with a fixed application deadline, such as the national scholarship, the more common mistake here is a missing document rather than a missed date — so it pays to collect the certificate from each academy well ahead of time.

Summary

The education expense tax credit subtracts 15% of what you spent directly from your tax bill, but the cap is tiered — 3 million won for preschool and K-12 children, 9 million won for a university-age child, and no cap for the wage earner's own expenses — and academy fees stop qualifying once a child starts elementary school. Academy fees paid by credit card can claim both the spending deduction and the tax credit, but the fact that those fees never show up automatically in the simplified service is the detail most people miss. As with other education-cost support programs whose conditions change every year, such as the list of universities restricted from student loans, the exact caps and eligible items should be reconfirmed each tax year through the National Tax Service's Hometax year-end guidance.
