Child Tax Credit

The Child Tax Credit is the largest direct tax benefit for families with children — a per-child credit of $2,200 in 2026 that reduces your federal tax liability dollar for dollar. Up to $1,700 of that is refundable (the Additional Child Tax Credit), meaning families who owe less than the credit amount can still receive the refundable portion as a cash refund. The credit phases out for higher earners: $200,000 AGI for single filers, $400,000 for married couples. The current amounts reflect the permanent law enacted under the One Big Beautiful Bill Act, which increased the credit from the $2,000 TCJA baseline. For a family with three qualifying children, that's $6,600 in direct tax reduction — one of the most meaningful levers in household tax planning.

Current Law (2026)

The Child Tax Credit (CTC) provides a per-child credit against federal income tax liability for qualifying children under age 17.

Legal Authority

• 26 U.S.C. § 24 — Child tax credit
• IRC Section 24(d) — Additional Child Tax Credit (refundable portion)
• IRC Section 24(h) — TCJA modifications (higher credit, higher phase-outs)

How It Works

To claim the Child Tax Credit, each qualifying child must meet five tests: they must be under 17 at the end of the tax year, a U.S. citizen, national, or resident alien, claimed as your dependent on your return, have lived with you for more than half the year, and not have provided more than half of their own support. See Dependent Claiming Rules for the complete tests and tiebreaker rules that apply when two parents both claim a child. Each qualifying child also needs a valid Social Security number issued before the tax return due date — a child with only an ITIN qualifies for the $500 Other Dependent Credit, not the full $2,200 CTC.

The credit is also partially refundable through the Additional Child Tax Credit (ACTC), which can generate a refund even if you owe no income tax. The ACTC refundable amount is calculated as 15% of earned income above $2,500, capped at $1,700 per child in 2026. A family with $22,000 in earned income and one qualifying child can receive roughly $1,700 in ACTC ($22,000 - $2,500 = $19,500 × 15% = $2,925, capped at the $1,700 limit) even with no income tax liability. This makes the ACTC a major component of working-poor family support alongside the EITC.

For higher earners, the credit phases out at $50 for every $1,000 of AGI above the threshold — $200,000 for single filers, $400,000 for married couples filing jointly. A married couple at $420,000 AGI loses $1,000 of credit per child ($20,000 excess ÷ $1,000 × $50), reducing the credit from $2,200 to $1,200 per child. The phase-out continues until the credit is fully eliminated: for a family with two children, the MFJ credit phases out completely at approximately $480,000 AGI. This interacts with your effective rate shown in federal income tax brackets.

Dependents who don't qualify for the full CTC — children 17 and older, elderly parents, and qualifying relatives — may still generate a separate $500 Other Dependent Credit, which is non-refundable. This runs off a separate calculation from the ACTC refundable structure and doesn't phase in or increase with earned income.

Historical Context

• Pre-TCJA (2017): $1,000 per child, phase-out at $110,000 MFJ
• 2018-2025 baseline: $2,000 per child, phase-out at $400,000 MFJ, with a separate $500 credit for other dependents
• ARP (2021 only): Temporarily expanded to $3,000/$3,600, fully refundable, advance monthly payments, age limit raised to 18
• 2026+: Maximum credit rises to $2,200, with the $500 other dependents credit retained and the higher phase-out thresholds continuing under current law

How It Affects You

If you're a working family with children under 17: The Child Tax Credit is $2,200 per child in 2026 — one of the largest individual line items on a family's tax return. A married couple earning $100,000 with two children receives $4,400 in credits, reducing their tax bill dollar-for-dollar. The credit begins phasing out at $400,000 for married filers, so it covers the vast majority of American families. Children must have valid Social Security numbers; ITIN-only children qualify only for the $500 Other Dependent Credit.

If you're a lower-income family claiming the ACTC: The Additional Child Tax Credit (ACTC) — the refundable portion — can generate a refund even if you owe no tax. The refundable amount is 15% of earned income above $2,500, capped at the $2,200 credit amount. A family earning $22,000 with one child can receive approximately $2,925 in ACTC ($22,000 - $2,500 = $19,500 × 15% = $2,925, capped at $2,200). For working-poor families, the ACTC combined with the EITC forms the core of federal work support.

If you're stacking credits with the dependent care credit: The CTC and the child and dependent care credit cover different things — CTC is for having a child, the dependent care credit is for childcare costs that enable you to work. You can claim both, but only for different expenses. A family with $4,000 in childcare costs can apply those costs to the dependent care credit, claim the CTC separately, and also use the $5,000 DC-FSA — maximizing three separate federal benefits simultaneously.

If your income fluctuated significantly in 2025-2026: The CTC is based on tax year income, not advance payments (advance monthly payments expired after 2021). There's no reconciliation risk for most families in 2026 — just claim the credit on your return. If your income exceeds the phase-out threshold ($400,000 MFJ), the credit phases out at $50 per $1,000 of excess income. At $420,000 MFJ, the credit per child is reduced by $1,000 — from $2,200 to $1,200.

State Variations

Several states offer their own child tax credits, often targeting lower-income families:

• CA: Young Child Tax Credit ($1,117 for children under 6, income below ~$30,000)
• CO: Child Tax Credit (5-30% of federal credit for families under $75,000)
• CT: $250 per child
• ID: $205 per child
• ME: $300 per child
• MD: Up to $500 per child for families under $15,000-$25,000
• MN: $1,750 per child for qualifying families
• NJ: Up to $1,000 per child
• NM: $600 per child under 4 (refundable)
• NY: 33% of federal credit (up to $330 per child)
• OR: $1,000 per child under 6
• VT: $1,000 per child under 6

Implementing Regulations

Tax regulations for the child tax credit are primarily found in 26 CFR section 1.24-1 (child tax credit computation) and 26 CFR section 1.32 (earned income credit interaction). The IRS has issued extensive guidance through Revenue Procedures and Notices rather than formal regulations for many CTC provisions.

• 26 CFR 1.24-1 — Partial credit for other dependents (the $500 nonrefundable Credit for Other Dependents under § 24(h)(4) for dependents who don't qualify for the Child Tax Credit, including older dependent children and qualifying relatives)

• HR2763 — American Family Act — Monthly CTC payments, $500 dependent credit, advance payment system (Rep. DeLauro, D-CT)

• HR353 — Family First Act — Remake CTC, add prenatal credit, expand EITC, eliminate Head of Household filing status (Rep. Moore, R-UT)

• HR463 — Lower Your Taxes Act — Monthly CTC payments plus bigger EITC for workers; offset by corporate/investment tax increases (Rep. Sykes, D-OH)

• HR1308 — FISC Act — Replace CTC entirely with new SSA-run monthly cash benefit for pregnant people and caregivers (Rep. Golden, D-ME)

• HR547 — No Child Tax Credit for Illegals Act — Require SSA-issued SSN for CTC eligibility (Rep. Van Drew, R-NJ)

• HR746 — America First Act — Tie CTC and other benefit eligibility to citizenship or lawful presence (Rep. Arrington, R-TX)

• HR1697 — Extend refundable CTC to Puerto Rico residents (Rescom. Hernández, D-PR)

• HR570 (Rep. Griffith, R-VA) — Would allow the Child Tax Credit for stillborn children carried 20+ weeks, aligning ID and eligibility rules with live births

Recent Developments

• Higher credit now in force for 2026: The One Big Beautiful Bill Act increased the maximum child tax credit to $2,200 per qualifying child beginning with tax year 2026, while preserving the $400,000/$200,000 phase-out thresholds and the $500 credit for other dependents.
• Tax Relief for American Families and Workers Act aftermath: The bipartisan deal that passed the House in early 2024 (expanding the refundable portion and adjusting for inflation) stalled in the Senate. Its provisions were not enacted, but many of its ideas — particularly a higher refundable floor — continue to appear in 119th Congress proposals.
• Monthly payment proposals: Multiple 119th Congress bills (HR 2763, HR 463, HR 1308) would shift the CTC to monthly advance payments, echoing the 2021 ARP experiment. The IRS has maintained the infrastructure built for 2021 advance payments, making future monthly distribution technically feasible.
• Immigration eligibility restrictions: Several bills (HR 547, HR 746) would tighten CTC eligibility based on immigration status, requiring SSA-issued SSNs or proof of citizenship. Current law already requires an SSN for the $2,000 credit but allows the $500 other dependents credit with an ITIN.
