Even families already receiving Korea's education benefit voucher often don't know exactly when the balance on the card actually expires. Application timing varies by household, but the usage deadline is fixed at March 31, 2027 for everyone. Because leftover balances don't automatically carry into the next school year, now -- September -- is a good time to check your balance and deadline before any of it goes to waste.

The application window and the usage deadline are different dates

The 2026 education benefit voucher's application window runs from April 1, 2026 through February 28, 2027 -- open for nearly a full year. But no matter when you actually apply, the usage period runs from the date your voucher is issued through March 31, 2027, a fixed endpoint. A family that applied early in April and one that applied near year-end will have their vouchers issued on different dates, which means the actual length of time they have to spend it differs too.

Why the deadline is March 31, 2027 and not tied to the school year

The education benefit voucher's budget is organized by fiscal year. Unlike the academic calendar, budget execution follows something closer to the government's fiscal year than the school year, so the program closes out for the year on March 31 -- a bit after the new semester actually starts in early March, not aligned with it. That's why a family who applies mid-semester can feel like they should be able to use the voucher into the following semester, when in fact the usage deadline closes right along with the end of the fiscal year.

Why it doesn't roll over -- last year's balance gets used first

The education benefit voucher is separated by fiscal year, so you can't combine balances from two different years into a single payment. There is a rule to the payment order, though: if you have leftover 2025 voucher funds and leftover 2026 voucher funds at the same time, the prior year's balance is deducted first, and only once that's used up does the current year's balance kick in. A newly issued card doesn't automatically draw only from the most recent year's budget -- which is also why your balance-check screen shows amounts split out by year.

Unused balances expire -- they aren't refunded

Once the usage period ends, any remaining balance simply expires. It isn't refunded in cash and it doesn't automatically roll into next year's budget, so as March approaches, checking your balance and planning your spending is what prevents losing money outright. Families applying for education benefit and education cost support for the first time should learn about this expiration structure right from the application stage.

What the voucher actually covers

The voucher is designed to cover a wide range of purchases at card-company-designated merchants, not just the specific items listed under education benefit support like school supplies and supplementary materials -- but online payments or certain business categories can be restricted, so it's worth checking the card company's published list of eligible merchants each year. Eligible categories can be looked up on your issuing card company's page (Shinhan, BC, Hana, etc.), and balance inquiries go through the same channel. Items paid directly to the school rather than through the card -- like meal fees or the free after-school course voucher -- run through a separate program entirely, so checking only your card balance can give you the wrong impression that all your support has run out.

Don't confuse it with other voucher programs

Several support programs share the word 'voucher' in their name, which makes them easy to mix up. The developmental rehabilitation service voucher, for example, is a completely separate program where the co-payment scales with income level, and its application window, eligibility criteria, and usage deadline are all different from the education benefit voucher. If your child is receiving multiple types of support at once, you need to track the deadline and balance for each program separately to avoid confusion.

Why September is the right time to check

If your household applied early back in April, you're already past roughly half of your usage window. Checking your balance now lets you plan whether to use the voucher first or pay cash for second-semester school supplies and materials. Families who haven't applied yet should also check whether they can claim the education expense tax credit at year-end filing as well, since it's a completely separate program from this voucher.

Step by step

1) Check your balance and the year-by-year breakdown on your card issuer's page 2) Mark March 31, 2027 on your calendar as the usage deadline 3) Understand that any prior-year balance gets used up first 4) Recheck the eligible-merchant list from your card company's notice 5) Decide whether to use the voucher first for second-semester school supplies and materials. Eligibility criteria, amounts, and merchant rules can be adjusted year to year, so confirm the exact details with the education benefit call center or your issuing card company.
