Introduction
The Child Tax Credit (CTC) is a U.S. federal tax benefit. It can cut the income tax a qualifying taxpayer owes, and its refundable portion can increase a refund.
It is not Australia's Family Tax Benefit, and it is not an Australian tax credit. This guide applies only if you have U.S. federal tax filing obligations, such as a U.S. citizen living in Australia.
Most families want five answers: how much, who qualifies, how income changes the credit, what changed under current law, and when refunds arrive.
Key Takeaways
- 2026 CTC is $2,200 per qualifying child, with up to $1,700 refundable as ACTC (caps are not additive).
- Qualifying child: under 17, claimed as a dependent, and holds a valid SSN.
- $3,000 and $3,600 figures are 2021 amounts or proposals, not 2026 law.
- File Form 1040 with Schedule 8812; your refund depends on the full return.
What Is the Child Tax Credit?
Credit versus deduction
A deduction reduces the income you are taxed on. A credit reduces the tax itself, dollar for dollar. That makes a credit generally more valuable than a deduction of the same size.
CTC versus ACTC
The CTC is nonrefundable. It can bring your tax to zero but no lower. The Additional Child Tax Credit (ACTC) is the refundable part: if the CTC exceeds your tax, some of the unused amount may come back as a refund, up to a cap and subject to earned-income rules.
That is why you can qualify for $2,200 per child yet receive less as a refund.
What "2026" means
The 2026 credit applies to tax year 2026, meaning income earned from January to December 2026. You generally file that return in 2027. Do not confuse it with the 2026 filing season, which covers tax year 2025.
How Much Is the Child Tax Credit for 2026? Key Updates and Proposals
Verified amounts
Public Law 119-21, section 70104, made the expanded CTC framework permanent. IRS Rev. Proc. 2025-32 confirms the 2026 figures, both unchanged from 2025:
- CTC: $2,200 per qualifying child
- ACTC cap: $1,700 per qualifying child (part of the $2,200)
The total credit is indexed for inflation after 2025, and the refundable cap has its own continuing adjustment. Increases round down to multiples of $100.
Income phase-out
The credit starts shrinking when modified adjusted gross income (MAGI) passes these thresholds:
| Filing status | Phase-out begins |
|---|---|
| Married filing jointly | $400,000 |
| Single, head of household, married filing separately | $200,000 |
The credit falls by $50 for every $1,000, or part of $1,000, above the threshold. Schedule 8812 rounds excess MAGI up to the next $1,000 and applies 5%. For example, $425 of excess becomes $1,000, and $1,025 becomes $2,000.
What changed
- Claimants now need an employment-valid SSN, beginning in 2025. Earlier instructions let taxpayers use ITINs.
- Qualifying children already needed employment-valid SSNs for CTC and ACTC.
- On a joint return, one spouse needs the valid SSN; the other needs a timely SSN or ITIN.
Proposals versus law
- $3,000 (ages 6-17) and $3,600 (under 6): temporary 2021 amounts under the American Rescue Plan Act (P.L. 117-2).
- American Family Act (H.R. 2763 / S. 1393): April 2025 bill still in committee; proposes monthly $300/$360 payments. Not law.
Treat any headline with higher figures as unenacted until the IRS confirms it. IRS 2026 instructions for Schedule 8812 are still a draft, so verify before filing.
Hypothetical example
Assume a married couple filing jointly, with MAGI of $90,000, two children under 17, and valid SSNs. Their potential CTC is $4,400.
If their income tax before credits is $3,000, the nonrefundable CTC wipes that out. The remaining $1,400 may be refundable as ACTC, if earned income supports it and it stays under the $3,400 combined cap ($1,700 × 2).
This is an illustration, not a guaranteed refund.
Who Qualifies for the Child Tax Credit in 2026?
Your child must meet every test below to claim the Child Tax Credit in 2026.
Qualifying child checklist
- Age: under 17 at year end
- Relationship: child, stepchild, eligible foster child, sibling, half-sibling, stepsibling, or a descendant of one of these
- Dependent: claimed as your dependent
- Residence: lives with you more than half the year
- Support: does not provide more than half of their own support
- Citizenship: U.S. citizen, U.S. national or U.S. resident alien
- Joint return: none filed, except solely to claim a refund of withheld or estimated tax
SSN requirement
The child needs an employment-valid SSN issued by the return's due date, including extensions. A child with only an ITIN or ATIN cannot receive the CTC, though they may qualify for the $500 Credit for Other Dependents.
Modified adjusted gross income (MAGI)
Phase-outs use MAGI. Start with adjusted gross income, then add back items such as excluded Puerto Rico income, foreign earned income and housing exclusions (Form 2555 lines 45 and 50), and American Samoa exclusions (Form 4563).
MAGI is not a single line on your return, so use the Schedule 8812 worksheet.
Special family situations
- Birth or death: residence is met if your home was the child's home for more than half the time they were alive.
- Temporary absences: illness, school, business, holidays, military service and juvenile detention can count as living with you.
Divorce or separation: the custodial parent is generally the one with more nights. With equal nights, the parent with higher AGI claims the child.
- Form 8332: lets the custodial parent release the CTC, ACTC and ODC claim. It does not transfer the EITC or care credit.
Filing from Australia
If you file from Australia, citizenship, residency, treaty and cross-border filing questions affect the whole return. Assess the CTC alongside your U.S. filing status and documentation, not on its own.
U.S. citizens in Australia may qualify for the CTC, but anyone filing Form 2555 cannot claim the ACTC. Expats generally get an automatic extension to 15 June, though interest on unpaid tax runs from April.
How to Claim the Child Tax Credit, ACTC, and Any Refund
Filing steps
- Report each qualifying child and their identification on Form 1040.
- Complete Schedule 8812.
- Use the schedule to calculate the nonrefundable and refundable portions.
How the ACTC is calculated
Part II-A of Schedule 8812 uses your unused CTC, the $1,700-per-child cap, and generally 15% of earned income above $2,500.
Filers with three or more qualifying children, and bona fide Puerto Rico residents, may use an alternative method in Part II-B based on Social Security and Medicare amounts less EITC. The result is still limited by unused credit and the per-child cap.
Credit versus refund
The credit amount is not your refund. The final figure depends on:
- Total tax liability
- Withholding and estimated payments
- Other credits and deductions
- The ACTC
- Any balance due
A family can claim the full credit and still owe tax.
Refund timing
Under the PATH Act (IRC 6402(m)), refunds on returns claiming the ACTC or EITC cannot be issued before 15 February for calendar-year filers. The hold covers the entire refund, not just the credit portion.
The IRS has said that most refunds issue within 21 days, with most eligible ACTC and EITC direct deposits expected by 2 March 2026. That is a filing-season benchmark for 2025 returns, not a promise for 2027. Use the IRS Where's My Refund? tool, which updates once daily.
Preparation checklist
- SSNs for you, your spouse and each child
- Proof of relationship and residence, where relevant
- Income records, including foreign income documents
- Form 8332 or custody paperwork
- Prior-year return
- Schedule 8812 and its instructions

Other Child-Related Credits and Australia-Specific Context
Credit for Other Dependents
The ODC is worth up to $500 per dependent and is nonrefundable. It covers dependents who do not qualify for the CTC, such as a 17-year-old or a child with an ITIN (Individual Taxpayer Identification Number). Phase-outs match the CTC: $200,000, or $400,000 jointly.
EITC and the Care Credit
The Earned Income Tax Credit is a refundable credit for taxpayers with low-to-moderate earned income. Maximum 2026 amounts, per IRS Rev. Proc. 2025-32:
| Qualifying children | Maximum EITC |
|---|---|
| None | $664 |
| One | $4,427 |
| Two | $7,316 |
| Three or more | $8,231 |
Form 2555 (Foreign Earned Income) filers cannot claim the EITC.
The Child and Dependent Care Credit covers work-related care costs for a child under 13 or an incapable dependent. In 2026 it is 20% to 50% of expenses, capped at $3,000 (one person) or $6,000 (two or more), so maximum credits are $1,500 and $3,000. It is nonrefundable.
You can claim the CTC, EITC and care credit on one return if you meet each credit's rules.
Not the Family Tax Benefit
Australia's Family Tax Benefit, run by Services Australia, is a separate two-part payment. Do not apply U.S. thresholds to Australian returns, and use official U.S. and Australian sources for any cross-border comparison.
Frequently Asked Questions
What is the maximum Child Tax Credit for 2026?
$2,200 per qualifying child, with up to $1,700 of that refundable as the ACTC. The actual benefit depends on eligibility, income, tax liability and current IRS rules.
Who is eligible for the Child Tax Credit in 2026?
The child must be under 17, your dependent, living with you over half the year, and a U.S. citizen, national or resident alien with a valid SSN. You also need a valid SSN, and income must fall within limits.
What are the income limits to qualify for the Child Tax Credit in 2026?
The phase-out starts at $400,000 MAGI for joint filers and $200,000 for everyone else. The credit drops $50 per $1,000 above that. Check the Schedule 8812 MAGI rules.
How will the Child Tax Credit affect my 2026 tax refund and when will refunds be issued?
The CTC reduces tax owed, and only the ACTC adds to a refund. Your full return determines the result. ACTC returns face a PATH Act hold, so check the IRS refund-status tool.
What are the major Child Tax Credit changes or proposals for 2026?
The $3,000 and $3,600 figures were temporary 2021 amounts. The American Family Act is a proposal only. Rely on IRS guidance rather than headlines.
What other child-related tax credits should I know about?
The ODC ($500, nonrefundable), EITC (refundable), and Child and Dependent Care Credit (nonrefundable) each have separate eligibility rules. They differ from the CTC and ACTC, and some can be claimed together.
