The child tax credit (CTC) is one of the most valuable tax breaks for families with dependent children. Under current federal law, you can claim up to $2,000 per qualifying child under age 17 at the end of 2024. This credit directly reduces the amount of tax you owe, potentially bringing your tax bill to zero. However, the rules surrounding refundability and timing can cause confusion, especially for parents expecting a large refund.

How the Child Tax Credit Works

First established in 1997, the child tax credit was originally worth $400 per child. It was expanded significantly by the Tax Cuts and Jobs Act of 2017, which raised the maximum to $2,000 per child and made a portion refundable through the additional child tax credit (ACTC). The current $2,000 limit is scheduled to expire after 2025, reverting to $1,000 per child unless Congress extends it.

To claim the CTC, you must have a qualifying child who is your dependent, under 17 at the end of the tax year, and has a valid Social Security number. The credit phases out for higher-income taxpayers: for married filing jointly, the phaseout begins at $400,000 of modified adjusted gross income; for other filers, it begins at $200,000.

There are two components: the nonrefundable portion and the refundable portion. The nonrefundable part can reduce your tax liability to zero but no further. If your tax liability is less than $2,000 per child, you may be eligible for the refundable ACTC, which can give you money back even if you owe no tax. For 2024, the maximum refundable amount is $1,700 per child.

Why Your Refund Might Be Delayed

The IRS is required by law to hold refunds that include the ACTC or the Earned Income Tax Credit (EITC) until mid-February. This is an anti-fraud measure designed to give the agency time to verify claims and prevent improper payments. The Protecting Americans from Tax Hikes (PATH) Act of 2015 mandated this delay.

If you file your return early in the season and claim the ACTC, you won't receive your refund before February 15. For 2025, the IRS states that if you file online with direct deposit and claim either the EITC or ACTC, you should receive your refund by March 3, 2025. That timeline applies to returns filed and accepted by mid-February.

If you only claim the standard, nonrefundable child tax credit, there is no delay—your refund follows normal processing times, which are typically 21 days for e-filed returns with direct deposit. The ACTC delay is the only child credit–related hold-up.

History and Future of the Credit

The child tax credit has been a political football for decades. In 2021, the American Rescue Plan temporarily expanded the credit to $3,600 per child for children under 6 and $3,000 for older children, and made it fully refundable. That expansion expired at the end of 2021, returning the credit to its current $2,000 level with partial refundability.

Several proposals in Congress seek to restore the 2021 expansion or make it permanent. The Tax Relief for American Families and Workers Act of 2024 passed the House but stalled in the Senate. As of 2025, no new legislation has been enacted, so the current rules remain in effect. If you want to maximize your refund, it’s important to understand how the refundable portion works and which dependents qualify.

How to Claim the Credit

You claim the child tax credit by filing Form 1040 and attaching Schedule 8812 (Credits for Qualifying Children and Other Dependents). The form requires the child’s name, Social Security number, and relationship to you. You’ll also need to calculate your earned income, because the ACTC is limited to 15% of your earned income above $2,500.

For example, if you earned $20,000 and have one child, your ACTC would be 15% of ($20,000 – $2,500) = $2,625, but capped at $1,700. If you have multiple children, the total refundable amount is capped at $1,700 per child, subject to the earned income limitation.

You can claim the credit even if you have no tax liability, as long as you have at least $2,500 of earned income. If your earned income is less than $2,500, you may not qualify for the ACTC, but you can still claim the nonrefundable portion if you have tax liability.

What to Do If You Haven’t Filed Yet

With Tax Day (April 15, 2025) fast approaching, now is the time to file. If you expect a refund, filing early is beneficial, but be aware that if you claim the ACTC, your refund will be held until March 3 at the earliest. If you need the money sooner, consider filing without the ACTC if you don’t qualify, but that’s rarely advantageous.

To avoid errors that cause further delays, double-check the child’s Social Security number and ensure you meet all qualifications. The IRS provides a free tool called the Interactive Tax Assistant to help determine eligibility. Also consider using free tax software through the IRS Free File program if your adjusted gross income is $79,000 or less.

If you have already filed and claimed the ACTC, track your refund using the “Where’s My Refund?” tool on IRS.gov or the IRS2Go app. Refund status is usually updated within 24 hours of e-filing. If your refund doesn’t arrive by March 3, check for a notice from the IRS requesting additional information.

State-Level Child Tax Credits

Several states offer their own child tax credits, which can supplement the federal credit. States like New York, California, Colorado, and Maine have refundable credits that don’t delay refunds beyond normal state processing times. However, state rules vary widely, so check your state’s tax agency website. Some states require separate forms, and amounts are typically modest—often $100 to $500 per child.

If you live in a state with no income tax, you won’t get a state-level credit, but you still benefit from the federal credit. Military families should also note that the child tax credit applies to dependents regardless of the parent’s duty station, as long as the child meets the residency and relationship tests.

Common Mistakes to Avoid

One frequent error is claiming the credit for a child who is not a dependent or who turns 17 before December 31. The age cut-off is strict: the child must be under 17 at the end of the tax year. Another mistake is incorrectly calculating earned income for the additional child tax credit. The IRS may disallow the credit if your earned income isn’t properly reported.

Also, be careful when filing jointly with a nonresident alien spouse. The credit rules differ for mixed-status families. You may need to file Form 8833 if you are taking a treaty position. Finally, don’t forget to include the child’s Social Security number for each dependent. Missing or incorrect SSNs are a top reason for refund delays.

The child tax credit remains one of the most effective tools for reducing the financial burden of raising children. By understanding the difference between the refundable and nonrefundable portions, you can accurately anticipate your refund timeline. While the mid-February hold on refunds containing the additional child tax credit is an inconvenience, it is temporary. As long as you file accurately and electronically with direct deposit, your refund should arrive by early March.
