Earned Income Tax Credit 2026 Apply by September 15

This content applies specifically to South Korea.
Facing Korea’s September 15, 2026 deadline for the first-half 2026 claim? You may choose the semiannual application if both you and your spouse have only earned income and meet the household, income, and property rules. Applications run from September 1 to September 15, and the assessed amount is scheduled for payment on December 17, 2026.
A notice is not proof of eligibility, and not receiving one does not prevent a direct Hometax application. Another easy mistake is treating the 35% payment formula as 35% of first-half wages.
Choose the application route that matches the income
Hometax is the Korean National Tax Service’s online tax portal. Notice recipients can use a mobile notice, its mailed QR code, ARS at 1544-9944, or Hometax; anyone without a notice can log in and select the direct-entry semiannual application.
If either spouse has business income or religious worker income, a regular application is required instead. A first-half application also counts as the second-half application, removing the need to submit again during the next second-half period.
How the Earned Income Tax Credit payment works
The December payment is based on 35% of the estimated annual calculated amount, not 35% of wages. Annual income is finalized and reconciled in June 2027. A higher final amount can produce an additional payment, while an overpayment may be recovered or offset.
A practical pre-submission checklist
- Confirm both spouses’ income types.
- Check household composition as of December 31, 2025 and property as of June 1, 2025.
- Prepare the notice authentication number or Hometax login, plus an account in the applicant’s name.
- Verify the current phone number, account number, and submission receipt.
This short check can prevent an incorrect filing choice or a delay caused by inaccurate account details.

Who should check first and what to do now
The couple’s combined 2025 total income and annualized 2026 earned income must be below KRW 22 million for a single-person household, KRW 32 million for a single-income household, or KRW 44 million for a dual-income household. Household property must be below KRW 240 million; liabilities are not deducted, and property of at least KRW 170 million reduces the calculated amount by 50%.
