(SOUTH KOREA) — South Korea’s government will distribute 1.8 trillion won in earned income and child tax credits to low-income working households under a restructuring announced June 24, 2026. The policy redirects child tax credit benefits from middle- and upper-income taxpayers toward households that need refundable support, with a maximum of 3.3 million won per household.

The restructuring marks a significant shift in how South Korea targets tax relief. Under prior policy, child tax credits functioned primarily as a tax-liability reduction for households with sufficient tax burden. That structure favored middle- and upper-income families who owed enough tax to benefit. The new framework makes the credit refundable for lower-income working households, meaning eligible families can receive payments even when their tax liability is zero.

Korean immigrants and visa holders in the United States who maintain financial ties to South Korea should understand how this policy compares to the U.S. tax credit system. Both countries operate earned income and child tax credits, but the eligibility rules, benefit amounts, and refundability structures differ in ways that affect dual-tax filers.

What Are the Earned Income Tax Credit and Child Tax Credit?

South Korea’s Earned Income Tax Credit (EITC), modeled loosely on the U.S. version, provides refundable support to low-income workers. The credit reduces tax liability and can result in a refund when the credit exceeds taxes owed. The Child Tax Credit (CTC) provides a per-child benefit that, under the new policy, is structured to reach households needing refundable support rather than only those with enough tax liability to use the credit.

The U.S. equivalents serve similar purposes but operate under different parameters. The U.S. EITC, claimed on Form 1040, is fully refundable for qualifying workers. For tax year 2026 (filed in 2027), the maximum U.S. EITC ranges from approximately $650 for filers with no children to roughly $8,100 for those with three or more qualifying children. The U.S. Child Tax Credit, governed by IRC Section 24, provides up to $2,000 per qualifying child under age 17, with up to $1,700 refundable as the Additional Child Tax Credit.

Korean nationals working in the U.S. on H-1B, L-1, or O-1 visas who meet the Substantial Presence Test are classified as tax residents and may claim both U.S. credits if they meet eligibility requirements. Nonresident aliens generally cannot claim the U.S. EITC, though some may qualify for the CTC under treaty provisions or if they elect resident status. IRS Publication 519, the U.S. Tax Guide for Aliens, details these residency classifications.

Eligibility and Qualification Criteria

South Korea’s restructured credits target low-income working households. Qualification depends on income thresholds, employment status, and household composition. The policy directs benefits to households with low tax liability, those who previously could not fully utilize non-refundable credits under the old system.

In the United States, EITC eligibility for tax year 2026 depends on earned income, filing status, and number of qualifying children. A single filer with one child must have earned income below approximately $50,000 to qualify. Married couples filing jointly get higher phase-out thresholds. Investment income cannot exceed approximately $12,000.

U.S. Child Tax Credit eligibility requires a qualifying child under 17 who lived with the filer for more than half the year. The filer must have a Social Security Number valid for employment. The credit begins phasing out at $200,000 adjusted gross income for single filers and $400,000 for married filing jointly.

⚠️ Warning: Korean immigrants filing U.S. returns cannot claim the U.S. CTC for a child who does not have an SSN issued by the tax return deadline. An ITIN is not sufficient for the CTC, though it works for other tax purposes.

How the 3.3 Million Won Maximum Is Calculated

South Korea’s 3.3 million won per-household ceiling combines earned income and child tax credits. The refundable portion depends on the household’s earned income and number of children. A family with two children and income near the lower threshold receives more than a single-child household at the same income level. The calculation phases out as income rises, consistent with how both the U.S. and Korean EITC structures operate.

For comparison, a U.S. family with two children earning $30,000 in tax year 2026 could receive roughly $6,100 from the EITC plus $4,000 from the CTC, with up to $3,400 refundable. That totals approximately $10,100, or about 13.5 million won at current exchange rates. The U.S. benefit ceiling is significantly higher, reflecting different policy goals and cost-of-living assumptions.

Comparison With Prior Years’ Tax Credit Policy

Previous South Korean policy favored middle- and upper-income households through child tax credits that reduced tax liability. Families without sufficient tax burden received little or no benefit. The shift to lower-income households represents the most significant restructuring of the Korean credit system in years and redirects an estimated 1.8 trillion won toward households that previously saw minimal benefit.

The U.S. underwent a similar debate during the expanded CTC period of 2021, when the credit became fully refundable and increased to $3,600 per child under 6. That expansion expired, and the CTC reverted to $2,000 with partial refundability. Both countries are now grappling with the same tension: whether child tax credits should function as tax relief for taxpayers with liability or as direct support for low-income families regardless of tax burden.

💡 Tax Tip: Korean nationals who are U.S. tax residents should check whether the U.S.-Korea tax treaty affects their ability to claim credits in both countries. Treaty Article 23 addresses double taxation relief but does not override credit eligibility rules in either jurisdiction.

Korean green card holders and long-term U.S. residents face additional complexity. The U.S. taxes worldwide income, including Korean-source earnings. Foreign tax credits claimed on Form 1116 may offset double taxation, but they do not interact directly with EITC or CTC eligibility. A household receiving Korea’s 3.3 million won credit while filing a U.S. return must still meet U.S. income and residency tests independently.

Several errors recur among cross-border filers. First, claiming the U.S. CTC for a child who lacks an SSN by the filing deadline disqualifies the credit entirely. Second, Korean residents who do not meet the U.S. Substantial Presence Test sometimes file Form 1040 instead of Form 1040-NR, incorrectly claiming refundable credits. Third, dual-status aliens in their first year of U.S. residency generally cannot claim the EITC, a rule in Publication 519 that catches many new arrivals.

📅 Deadline Alert: For tax year 2026 (filed in 2027), the U.S. filing deadline is April 15, 2027. The FBAR deadline is also April 15, 2027, with an automatic extension to October 15, 2027.

You Are Eligible If.

You may qualify for South Korea’s restructured credits if you are a low-income working household with earned income below the established thresholds, you have dependent children, and your prior tax liability was too low to fully benefit under the old non-refundable structure.

You may qualify for the U.S. equivalents if you are a tax resident through a green card or the Substantial Presence Test, you have earned income within EITC phase-out ranges, and your qualifying children have SSNs valid for employment by the filing deadline.

You are a dual-status alien if you changed visa status mid-year, such as moving from F-1 to H-1B. In that case, file Form 1040 with Form 1040-NR attached, and consult Publication 519 for dual-status filing rules. Dual-status aliens generally cannot claim the EITC.
