What is the Child Tax Credit?

The Child Tax Credit, or CTC, is a federal tax benefit for eligible taxpayers who have qualifying children. A tax credit reduces the amount of federal income tax owed, subject to the rules that apply to the tax year and the taxpayer.

The credit is different from a tax deduction. A deduction generally reduces taxable income, while a tax credit is applied against tax liability. Depending on the law and the taxpayer circumstances, some portion of a credit may be refundable, meaning an eligible taxpayer could receive a refund even when the credit exceeds the tax owed.

The amount, refundable portion and eligibility conditions can change when federal tax law changes. Families should use IRS instructions for the specific tax year rather than relying on an older article or a payment amount advertised for a previous year.

Which tax year does the 2026 Child Tax Credit cover?

The phrase 2026 Child Tax Credit can refer to the credit for income earned during the 2026 tax year. Most individual taxpayers report that income on a federal tax return filed in 2027.

This distinction matters because a return filed during 2026 generally reports income earned during the 2025 tax year. The applicable credit amount, income threshold, refundable rules and forms must match the tax year being reported.

If you are preparing a return now, check whether you need the IRS rules for tax year 2025 or tax year 2026. Do not use the rules for one year to calculate the credit for another year.

Who may qualify for the Child Tax Credit in 2026?

Eligibility depends on the child meeting the IRS qualifying child requirements and the taxpayer meeting the relevant tax and identification rules. The credit is not automatically available for every child who lives with a taxpayer.

• Age requirement: The child generally must be under age 17 at the end of the tax year for the Child Tax Credit.
• Relationship requirement: The child generally must be the taxpayer child, stepchild, eligible foster child, sibling, stepsibling or a descendant of one of these relatives under IRS rules.
• Residency requirement: The child generally must have lived with the taxpayer for more than half of the tax year, subject to exceptions.
• Support requirement: The child generally must not have provided more than half of their own support during the tax year.
• Dependent requirement: The child generally must be claimed as a dependent under the applicable IRS rules.
• Identification requirement: The child and taxpayer must meet the relevant Social Security number and taxpayer identification requirements.
• Income rules: The taxpayer must consider the modified adjusted gross income thresholds and phaseout rules.

Special rules may apply to children born during the year, children of divorced or separated parents, temporary absences, foster placements and certain other family situations. Review the IRS instructions if your household circumstances are unusual.

What counts as a qualifying child?

A qualifying child must meet several tests. The age test is only one part of the determination. The IRS also considers the relationship between the child and taxpayer, where the child lived, support rules and whether the child is eligible to be claimed as a dependent.

Use the IRS qualifying child guidance and the instructions for the relevant tax year if you are uncertain whether a child meets all required tests.

Child Tax Credit income limits and phaseout rules

The Child Tax Credit is subject to modified adjusted gross income limits. Above the applicable threshold, the credit is reduced under the phaseout rules. The relevant income figure is not necessarily the same as take-home pay or gross wages.

For tax years governed by the rules reinstated under federal legislation enacted in 2025, the commonly applicable phaseout thresholds are $200,000 for most filing statuses and $400,000 for married taxpayers filing jointly. These thresholds should be verified against the IRS instructions for the specific tax year and the taxpayer situation.

The phaseout thresholds are not the same as an income limit that automatically disqualifies every taxpayer above a particular salary. The reduction is calculated under the applicable rules. Use the correct tax-year form or tax software to determine the amount.

How much is the Child Tax Credit for tax year 2026?

The maximum credit depends on the federal law applicable to the 2026 tax year and the taxpayer eligibility details. Under legislation enacted in 2025, the Child Tax Credit maximum was increased to $2,200 per qualifying child for tax years beginning after December 31, 2024, subject to applicable requirements and inflation adjustments where provided by law.

The amount a family can actually claim may be lower because of income phaseouts, tax liability, qualifying child rules and refundable credit requirements. The maximum amount should not be interpreted as a guaranteed payment to every parent.

Before filing a 2026 tax return in 2027, confirm the final amount and instructions published by the IRS for that tax year. A taxpayer may qualify for the full credit, a reduced credit or no credit depending on the facts of the case.

Refundable Child Tax Credit and the Additional Child Tax Credit

A refundable tax credit can result in a refund when the allowed credit exceeds the taxpayer tax liability, provided the taxpayer meets the applicable rules. The Additional Child Tax Credit, or ACTC, is the refundable portion of the Child Tax Credit for eligible taxpayers.

Refundability is subject to conditions, including qualifying child requirements, earned income rules and identification requirements. It is not a separate automatic payment for every household with children.

Under the rules introduced by legislation enacted in 2025, the refundable amount is generally limited to $1,700 per qualifying child for the relevant tax years, subject to applicable requirements and adjustments provided by law. The exact amount and calculation should be confirmed in the IRS instructions for tax year 2026.

Why earned income matters

The ACTC calculation can depend on earned income and the number of qualifying children. A taxpayer who has little or no earned income may not qualify for the same refundable amount as a taxpayer who meets the applicable earned income requirements.

Use the applicable IRS schedule and instructions instead of estimating a refund from the maximum credit alone. The final tax calculation can also be affected by other credits, withholding and the rest of the tax return.

Social Security number and identification requirements

The Child Tax Credit has specific taxpayer identification requirements. Under federal rules applicable to recent tax years, the qualifying child generally must have a valid Social Security number issued by the Social Security Administration that meets the required conditions.

The taxpayer claiming the credit must also meet the applicable identification requirements. The rules for a taxpayer identification number, filing status and qualifying child documentation can affect eligibility, so check the instructions for the exact tax year.

• Check that the child name and Social Security number match official records.
• Review the IRS rules about when the Social Security number must be issued.
• Confirm the taxpayer identification requirements for the person claiming the credit.
• Do not use an incorrect or borrowed identification number on a tax return.
• Contact the Social Security Administration if a name or number record needs correction.

How to claim the Child Tax Credit on a tax return

Eligible taxpayers generally claim the Child Tax Credit by filing a federal income tax return and providing the information required for qualifying children. The forms and schedules depend on the tax year and the taxpayer circumstances.

1. Choose the correct tax year. If you are reporting income earned in 2026, use the 2026 tax-year rules when preparing the return in 2027.
2. Gather family information. Collect the names, dates of birth, Social Security numbers and residency information required for qualifying children.
3. Determine eligibility. Review age, relationship, residency, support, dependent and identification requirements.
4. Calculate modified adjusted gross income. Use the IRS definition and applicable worksheet rather than take-home pay.
5. Complete the required tax forms. Follow the IRS instructions for the Child Tax Credit and any applicable refundable credit schedule.
6. Review the full return. Check filing status, income, deductions, withholding and other credits before submitting.
7. File through an accepted method. Use IRS-supported electronic filing options, eligible tax preparation services or an accepted paper return method.
8. Keep records. Save a copy of the return and supporting documents in case the IRS requests additional information.

If you are unsure whether a child qualifies or how the refundable portion is calculated, consult the official IRS instructions or a qualified tax professional.

IRS filing information

Documents to prepare before filing

Keeping records organized can help reduce filing errors and make it easier to respond if the IRS requests verification.

Not every taxpayer needs every document. The IRS may request additional evidence in certain cases, especially when a child is claimed by more than one taxpayer or residency is unclear.

Special situations: Divorced parents, shared custody and new babies

Divorced or separated parents

Special rules can determine which parent may claim a child. In some circumstances, the custodial parent may release a claim to the noncustodial parent using the required IRS procedure. A custody agreement by itself may not satisfy all federal tax requirements.

Children born during the tax year

A child born during the year may qualify even though the child did not live with the taxpayer for a full calendar year, subject to the applicable IRS rules. Parents should ensure the child identification information is correct and follow the year-specific filing instructions.

A child claimed by another taxpayer

Only the taxpayer who meets the relevant IRS rules may claim the child for the credit. If two returns claim the same child, the IRS may ask for additional information or apply tie-breaker rules.

Older children

A child who is age 17 or older at the end of the tax year generally does not qualify for the Child Tax Credit. Depending on age, student status, support and other conditions, a taxpayer may qualify for a different dependent-related credit.

Common Child Tax Credit mistakes to avoid

• Using rules or credit amounts from the wrong tax year.
• Claiming a child who does not meet the age or dependent requirements.
• Entering a name or Social Security number that does not match official records.
• Assuming every taxpayer receives the maximum credit as a cash refund.
• Ignoring modified adjusted gross income phaseout rules.
• Claiming a child without checking custody and residency rules.
• Leaving out required forms or schedules for the refundable portion.
• Paying a preparer who promises a guaranteed refund regardless of eligibility.

A careful review before filing can reduce errors and help avoid processing delays. If the IRS questions a claim, respond to the notice using the stated deadline and submission instructions.
