What is the Child Tax Credit (CTC)?

The Child Tax Credit (CTC) is a federal tax benefit designed to help families with the cost of raising children. It provides a dollar-for-dollar reduction in your tax bill for each qualifying child under age 17. The CTC was first introduced in 1997 and has since undergone several significant changes to expand its reach and impact for American families.

Key Legislative Changes:

• In 2021, the American Rescue Plan Act (ARPA) temporarily increased the CTC to up to $3,600 per child under age 6 and $3,000 per child ages 6–17, made the credit fully refundable, and allowed monthly advance payments.
• These enhancements expired after 2021, and for tax years 2022 through 2025, the CTC reverted to its pre-ARPA structure: up to $2,000 per qualifying child under age 17, with up to $1,700 of that amount refundable as the Additional Child Tax Credit (ACTC), indexed for inflation.
• Unless Congress acts, the CTC is set to decrease to $1,000 per child and phase out at lower income levels after 2025.

2024–2025 Updates:

• For 2025, the maximum Child Tax Credit remains at $2,000 per qualifying child, with up to $1,700 refundable for eligible families.
• The credit begins to phase out for single filers with modified adjusted gross income (MAGI) above $200,000 and for married couples filing jointly above $400,000.
• The child must have a valid Social Security Number (SSN) and meet all other qualifying criteria.

How Much is the Child Tax Credit Worth?

For the 2025 tax year, the Child Tax Credit (CTC) is worth up to $2,000 per qualifying child under age 17. This credit is designed to directly reduce your tax bill on a dollar-for-dollar basis, making it one of the most valuable tax breaks for families.

Refundable vs. Non-Refundable Portions

• Non-Refundable Portion: The CTC first reduces your tax liability. If the credit brings your tax bill to zero, any remaining unused portion may be refundable.
• Refundable Portion  (Additional Child Tax Credit, ACTC): For 2025, up to $1,700 per child can be refunded to you if your credit exceeds your tax liability and you meet certain income requirements. This ensures that even families with little or no tax owed can benefit from the credit.

Table: 2025 Child Tax Credit Breakdown

Example:
If you have two qualifying children and owe $1,500 in federal taxes, you could use $1,500 of your $4,000 total CTC ($2,000 x 2) to bring your tax bill to zero. If you meet the income and other requirements, you could receive up to $1,700 per child ($3,400 total) as a refund for the unused portion.

Note: The CTC is scheduled to revert to $1,000 per child after 2025 unless Congress extends the current provisions.

• Gather your income documents (W-2s, 1099s) and your tax return (Form 1040)

2. Fill Out Schedule 8812 (Form 1040)

• When preparing your 2025 tax return (filed in 2026), enter your dependents on Form 1040
• Complete and attach Schedule 8812 to calculate the refundable portion of the credit

3. Use Tax Software or Hire a Tax Preparer

• If your situation is complex or you want peace of mind, consider hiring a tax professional

4. File Before the Deadline

Common Mistakes to Avoid

Avoiding common mistakes when claiming the Child Tax Credit is essential to prevent delays or denials of your refund. Here are the top errors and how to fix them:

• Claiming a non-qualifying child
  • Mistake: Attempting to claim a child who does not meet IRS requirements (age, relationship, residency, support, or SSN criteria).
  • How to Fix: Double-check that your child meets all IRS eligibility tests before filing. Use tax software or consult a tax professional if you’re unsure.

• Incorrect SSN
  • Mistake: Entering an invalid, missing, or incorrect Social Security Number for your child. The IRS requires a valid SSN, not an ITIN, issued before the tax return due date.
  • How to Fix: Ensure you have your child’s official SSN before filing. For newborns or recent adoptions, wait until the SSN is issued. If you don’t have it by the deadline, file for an extension, but pay any taxes owed to avoid penalties.
• Overstating income
  • Mistake: Reporting income that is too high, which can phase out or eliminate your CTC eligibility.
  • How to Fix: Accurately report your Modified Adjusted Gross Income (MAGI) and review IRS phase-out thresholds. Use reliable tax software or a preparer to minimize errors.
• Forgetting to file Schedule 8812
  • Mistake: Not attaching Schedule 8812 with your Form 1040, which is required to calculate and claim both the refundable and non-refundable portions of the credit.
  • How to Fix: Always complete and attach Schedule 8812 when claiming the CTC. Tax software typically includes this automatically, but double-check before submitting your return.

Pro Tip: If your CTC claim is denied due to an error, you may need to file Form 8862 with your next return to reclaim the credit.

FAQs: Child Tax Credit 2025

1. Is the Child Tax Credit refundable in 2025?
   Yes, the Child Tax Credit is partially refundable in 2025. Up to $1,700 per qualifying child can be refunded to you through the Additional Child Tax Credit (ACTC), depending on your earned income and other eligibility requirements.
2. Can I claim the Child Tax Credit without income?
   You generally need at least $2,500 in earned income to qualify for the refundable portion of the credit. Without earned income, you cannot receive the ACTC, but you may still use the non-refundable portion to reduce your tax liability if you owe taxes.
3. What if my child was born in December?
   If your child was born at any point during the year, including December, you may claim the Child Tax Credit for that tax year as long as your child meets all other requirements, such as having a valid SSN and being your dependent.
4. How does the IRS verify dependents?
   The IRS matches the Social Security Number, date of birth, and relationship information you provide with government records. If there are discrepancies or duplicate claims, the IRS may request additional documentation.
5. What if both parents claim the same child?
   The IRS applies tie-breaker rules: the parent with whom the child lived the longest during the year gets the credit. If time is equal, the parent with the higher income claims the child. Duplicate claims can delay or deny the credit until resolved. 

Here are the detailed IRS answers to common questions about eligibility, dependents, and filing requirements for the Child Tax Credit.
