You likely qualify for the Child Tax Credit if you have a child under age 17 who lived with you for more than half the year, is a U.S. citizen with a Social Security Number, and you meet income limits. Under Internal Revenue Code Section 24, Congress created this credit to reduce federal income tax for working families with children. This tax benefit reduces your tax bill dollar-for-dollar, meaning a $2,200 credit cuts your tax owed by $2,200.
The credit does not reduce your taxable income like a deduction does. Instead, it directly lowers the actual tax you owe to the federal government. When your credit exceeds your tax liability, you may receive the difference as a refund through the Additional Child Tax Credit.
According to the National Taxpayer Advocate’s 2025 report, more than 40 million American families claim the Child Tax Credit each year, but low-income families miss out on thousands of dollars because they do not understand eligibility rules. The IRS denies over 18 million credit claims annually due to filing errors, incorrect documentation, or failure to meet qualification tests. These denials result in delayed refunds, lost money, and potential penalties of up to 20 percent of the excessive claim amount.

Understanding Internal Revenue Code Section 24
The Child Tax Credit exists under 26 U.S. Code Section 24, which Congress enacted in 1997 as part of the Taxpayer Relief Act. This federal statute created a nonrefundable credit to help middle-income working families offset the costs of raising children. The original credit amount was $400 per child, available only to families who owed federal income tax.
Over the years, Congress expanded the credit multiple times. The Tax Cuts and Jobs Act of 2017 increased the credit from $1,000 to $2,000 per qualifying child and raised income phase-out thresholds. This law also created the Additional Child Tax Credit, making up to $1,400 refundable for families with little or no tax liability.
The One Big Beautiful Bill Act, signed into law on July 4, 2025, made additional changes. This legislation increased the credit to $2,200 per child for tax year 2025 and beyond. The refundable portion increased to $1,700 per qualifying child.
The law also added new Social Security Number requirements. Both the child and the person claiming the credit must now have a valid SSN issued before the tax return due date. For married couples filing jointly, only one spouse needs an SSN to claim the credit.
The Eight Qualification Tests
Your child must pass eight separate tests to qualify for the Child Tax Credit. Missing even one test disqualifies the child from the credit. These tests ensure that only eligible dependents receive the benefit and prevent multiple taxpayers from claiming the same child.
Test 1: Age Requirement
Your child must be under age 17 at the end of the tax year. If your child turns 17 on December 31, 2025, they do not qualify for the credit for that year. The IRS counts the child’s age on the last day of the calendar year, not when you file your return.
A child who turns 16 on any date during the year qualifies for the full credit. A child born on January 1 counts as being one year older on the preceding December 31. This means a child born on January 1, 2009, would turn 17 on December 31, 2025, and would not qualify for the 2025 tax year credit.
If your child is 17 or older, you cannot claim the Child Tax Credit. However, you may qualify for the Credit for Other Dependents, worth up to $500. This nonrefundable credit applies to dependents who do not meet the age requirement for the Child Tax Credit.
Full-time college students aged 19 to 24 can still be claimed as dependents. They do not qualify for the Child Tax Credit but may qualify for the Credit for Other Dependents. Permanently disabled children of any age may also qualify for the Credit for Other Dependents.
Test 2: Relationship Requirement
The child must be related to you in one of the following ways. Your biological son, daughter, stepchild, or adopted child qualifies under this test. A legally placed foster child placed by an authorized agency or court order also meets the relationship requirement.
Your brother, sister, stepbrother, stepsister, half-brother, or half-sister qualifies. A descendant of any of these relatives qualifies, including your grandchild, niece, or nephew. This broad definition allows many family members to claim the credit for children in their care.
An adopted child is treated as your own child. A child lawfully placed with you for legal adoption qualifies, even if the adoption is not final by year-end. The IRS does not distinguish between biological children and legally adopted children for tax purposes.
A foster child must be placed with you by a state or local government agency, an Indian tribal government, a tax-exempt organization licensed by a state, or a court order. Informal foster care arrangements where you care for a relative’s child without legal placement do not meet the relationship test unless another relationship category applies.
Test 3: Support Test
The child cannot provide more than half of their own financial support during the tax year. You must calculate all sources of support, including money the child earns, scholarships, Social Security benefits, and gifts from others. If the child’s own contributions exceed 50 percent of their total support costs, they fail this test.
Support includes food, shelter, clothing, education, medical care, recreation, transportation, and similar necessities. You calculate the total cost of these items and determine what portion the child provided from their own funds. Savings accounts and investments in the child’s name do not count as support unless the child actually spends those funds.
Scholarships received by a full-time student do not count as support provided by the child. This exception helps families with children attending college. The IRS Publication 501 provides worksheets to help you calculate support percentages when the situation is complex.
If you and another person together provide more than half the child’s support, but neither of you alone provides more than half, special rules apply. You may be able to claim the child under a multiple support agreement if certain conditions are met.
Test 4: Dependent Status
You must claim the child as a dependent on your federal tax return. The child cannot file a joint return for the year, unless they file the return only to claim a refund of withheld taxes or estimated payments. A married child who files jointly with a spouse generally cannot be claimed as your dependent.
The child must be a qualifying child or qualifying relative as defined in Internal Revenue Code Section 152. This means they must meet all dependency tests, including the relationship, age, residency, support, and joint return tests. These requirements overlap with the Child Tax Credit tests but have some technical differences.
You must include the child’s name, Social Security Number, and relationship to you in the Dependents section of Form 1040. Checking the box that indicates the child qualifies for the Child Tax Credit is essential. Failure to properly claim the child as a dependent disqualifies you from the credit.
Only one taxpayer can claim a child as a dependent in any tax year. If two people claim the same child, the IRS uses tie-breaker rules to determine who has priority. These rules generally favor the parent with whom the child lived for more nights during the year.
Test 5: Citizenship Test
The child must be a U.S. citizen, U.S. national, or U.S. resident alien. A U.S. national refers to individuals born in American Samoa or the Commonwealth of the Northern Mariana Islands. These individuals have a special status under U.S. immigration law.
A U.S. resident alien is someone who meets the green card test or substantial presence test under Internal Revenue Code Section 7701(b). The green card test applies to individuals who are lawful permanent residents at any time during the calendar year. The substantial presence test requires the person to be physically present in the United States for at least 31 days during the current year and 183 days during a three-year period.
Children who are foreign nationals without green cards or substantial presence do not qualify. This includes children of undocumented immigrants and children on temporary visas who do not meet the substantial presence requirement. Congress created this restriction to limit the credit to children with strong connections to the United States.
Starting with tax year 2025, the child must also have a valid Social Security Number issued before the tax return due date. An Individual Taxpayer Identification Number (ITIN) or an Adoption Taxpayer Identification Number (ATIN) does not satisfy this requirement for the Child Tax Credit. However, children with ITINs or ATINs may still qualify for the Credit for Other Dependents.
Test 6: Residency Test
The child must live with you for more than half the tax year. This means more than 183 days in a 365-day year or more than 184 days in a 366-day leap year. The IRS counts every night the child slept in your home, including nights the child was absent for temporary reasons.
Your home is any location where you regularly live. It does not need to be a traditional house or apartment. If you and your child lived together in a homeless shelter for more than half the year, that counts as meeting the residency test.
Temporary absences count as time lived with you. These include absences for illness, hospitalization, school attendance, vacation, business, military service, or detention in a juvenile facility. The key is that the absence must be temporary with the intention that the child will return to your home.
A child who was born or died during the year is treated as living with you for the entire year if your home was the child’s home for the entire time the child was alive. This special rule helps parents who lose a child during the year to still claim the credit.
Special exceptions apply to children of divorced or separated parents. The custodial parent is the parent with whom the child lived for the greater number of nights. If the child lived with each parent for an equal number of nights, the parent with the higher adjusted gross income is considered the custodial parent.
Test 7: Income Thresholds
You qualify for the full credit if your Modified Adjusted Gross Income (MAGI) does not exceed certain thresholds. For tax year 2026, these thresholds are $400,000 for married couples filing jointly and $200,000 for all other filing statuses. These amounts remain the same for 2025.
Your MAGI equals your Adjusted Gross Income from Form 1040, line 11, plus certain exclusions added back. These exclusions include foreign earned income exclusion, foreign housing exclusion or deduction, and exclusion of income from Puerto Rico or American Samoa. Most taxpayers will find that their MAGI equals their AGI because these exclusions are uncommon.
The credit phases out at a rate of $50 for each $1,000 your MAGI exceeds the threshold. The IRS rounds up partial amounts to the next $1,000. If your MAGI is $201,500 as a single filer, the excess is $1,500, which rounds to $2,000. This reduces your credit by $100 ($50 × 2).
The credit completely phases out when your MAGI reaches a certain level. For one child, the credit disappears at $244,000 for single filers and $484,000 for joint filers. Each additional child extends the phase-out range because the base credit amount is higher.
Test 8: Social Security Number Requirement
Starting in 2025, both you and your child must have valid Social Security Numbers to claim the credit. This new requirement eliminates mixed-status families from eligibility unless at least one parent has an SSN. The SSN must be valid for employment in the United States.
Your child’s SSN must be issued before the due date of your tax return, including extensions. If you file on April 15 without an extension, the child must have received their SSN by that date. If you file for an extension until October 15, the child must receive their SSN by October 15.
For married couples filing jointly, at least one spouse must have a valid SSN. The other spouse can have an ITIN. This change particularly affects families where one spouse is a U.S. citizen and the other is not yet eligible for an SSN.
An ITIN does not qualify for the Child Tax Credit under the new rules. However, families with ITINs may still claim the Credit for Other Dependents, which has different identification requirements. The ITIN requirement for the Credit for Other Dependents remains unchanged.
Calculating Your Child Tax Credit Amount
The maximum credit is $2,200 per qualifying child for tax year 2025 and 2026. If you have three qualifying children, your base credit amount is $6,600 before any phase-out reductions apply. This calculation is straightforward when your income falls below the threshold amounts.
To calculate your actual credit, follow these steps. First, multiply the number of qualifying children by $2,200 to find your base amount. Second, calculate your MAGI by adding certain exclusions back to your AGI. Third, compare your MAGI to the threshold for your filing status.
If your MAGI exceeds the threshold, subtract the threshold from your MAGI. Round up the difference to the nearest $1,000. Multiply that number by $50. Subtract the result from your base credit amount to find your final credit.
Here is an example calculation for a married couple filing jointly with two children and MAGI of $425,000. Base credit: 2 children × $2,200 = $4,400. MAGI exceeds threshold by: $425,000 – $400,000 = $25,000. No rounding needed because $25,000 is a multiple of $1,000. Phase-out reduction: 25 × $50 = $1,250. Final credit: $4,400 – $1,250 = $3,150.
| Filing Status | Income Threshold | Credit Begins Phase-Out | Credit Fully Phases Out (1 Child) |
|---|---|---|---|
| Single | $200,000 | $200,001+ | $244,000+ |
| Head of Household | $200,000 | $200,001+ | $244,000+ |
| Married Filing Jointly | $400,000 | $400,001+ | $484,000+ |
| Married Filing Separately | $200,000 | $200,001+ | $244,000+ |
The child tax credit is nonrefundable. This means it can only reduce your tax liability to zero. If you owe $1,500 in tax and have a $2,200 credit, the credit wipes out your tax bill completely. However, you do not receive the remaining $700 as a refund through the nonrefundable portion.
Some taxpayers qualify for the Additional Child Tax Credit, which is refundable. This credit allows you to receive up to $1,700 per qualifying child as a refund, even if you owe no tax. Specific requirements apply to claim this refundable portion.
The Additional Child Tax Credit (ACTC)
The Additional Child Tax Credit is the refundable portion of the Child Tax Credit. You can receive up to $1,700 per child as a refund through this credit for tax years 2025 and 2026. This amount increases from $1,600 in 2024 and continues to adjust annually for inflation.
To qualify for the ACTC, you must first meet all eight qualification tests for the Child Tax Credit. Your child must be under 17, related to you, not provide more than half their own support, be claimed as your dependent, be a U.S. citizen or resident with an SSN, live with you for more than half the year, and you must meet income limits and SSN requirements.
You must also have earned income of at least $2,500 to claim the ACTC. Earned income includes wages, salaries, tips, professional fees, and net earnings from self-employment. Unearned income such as interest, dividends, capital gains, pensions, unemployment, and Social Security benefits does not count toward the $2,500 threshold.
The ACTC phases in at a rate of 15 percent of your earned income above $2,500. If you earned $20,000, your earned income above the threshold is $17,500. Your maximum ACTC would be $17,500 × 0.15 = $2,625. However, the ACTC is capped at $1,700 per qualifying child, so you would receive $1,700 per child.
Families with three or more qualifying children may calculate the ACTC using an alternate method based on their Social Security taxes. This method may result in a higher refundable credit. The IRS Schedule 8812 instructions provide worksheets to help you determine which calculation method gives you a larger credit.
The IRS will not issue ACTC refunds before mid-February. This delay results from the PATH Act, which Congress passed to combat fraud. The IRS uses this time to verify income, children, and other information before releasing refunds.
Three Common Scenarios: Who Qualifies and How Much
Understanding real-world scenarios helps you determine whether you qualify and how much you can receive. These three examples represent the most common situations taxpayers face when claiming the Child Tax Credit.
Scenario 1: Single Parent with Two Children, Low Income
Maria is a single mother with two children, ages 5 and 8. She works as a nurse and earned $45,000 in 2025. Her children lived with her all year, both are U.S. citizens with valid Social Security Numbers, and she claims them as dependents. Maria’s adjusted gross income is $45,000, which is well below the $200,000 threshold.
| Factor | Details |
|---|---|
| Number of Qualifying Children | 2 (ages 5 and 8) |
| Base Credit Amount | $4,400 (2 × $2,200) |
| MAGI | $45,000 |
| Phase-Out Reduction | $0 (below threshold) |
| Nonrefundable Credit Applied | $4,400 reduces tax to $0 |
| Tax Liability Before Credit | $2,800 |
| Tax After Credit | $0 |
| Remaining Credit | $1,600 |
| ACTC Calculation | ($45,000 – $2,500) × 0.15 = $6,375 |
| Refundable Amount | $1,600 (lesser of remaining credit or $3,400 ACTC limit for 2 children) |
Maria receives the full $4,400 credit. The credit first reduces her $2,800 tax liability to zero. The remaining $1,600 comes back to her as a refund through the Additional Child Tax Credit. She meets the earned income requirement because her salary of $45,000 exceeds $2,500.
Scenario 2: Married Couple with Three Children, High Income
David and Jennifer file jointly and have three children ages 4, 10, and 14. David works as an engineer earning $250,000. Jennifer works as a teacher earning $180,000. Their combined adjusted gross income is $430,000. All three children lived with them all year, are U.S. citizens with valid SSNs, and are claimed as dependents.
| Factor | Details |
|---|---|
| Number of Qualifying Children | 3 (ages 4, 10, and 14) |
| Base Credit Amount | $6,600 (3 × $2,200) |
| MAGI | $430,000 |
| Amount Above Threshold | $30,000 ($430,000 – $400,000) |
| Phase-Out Reduction | $1,500 (30 × $50) |
| Final Credit Amount | $5,100 ($6,600 – $1,500) |
| Tax Liability Before Credit | $48,000 |
| Tax After Credit | $42,900 ($48,000 – $5,100) |
| Refundable Portion | $0 (credit does not exceed tax liability) |
David and Jennifer receive a reduced credit of $5,100 because their income exceeds the $400,000 threshold for joint filers. The credit reduces their federal tax bill by $5,100. They do not receive any refundable portion because their tax liability exceeds the credit amount. Their high income disqualifies them from the Additional Child Tax Credit phase-in calculation.
Scenario 3: Divorced Parents with Shared Custody
Robert and Lisa divorced in 2023 and share custody of their son, age 12. The divorce decree does not specify who claims the child for tax purposes. Their son spent 180 nights with Robert and 185 nights with Lisa during 2025. Lisa earns $80,000 as a marketing manager. Robert earns $95,000 as an accountant.
| Factor | Lisa (Custodial Parent) | Robert (Noncustodial Parent) |
|---|---|---|
| Nights Child Lived With Parent | 185 nights | 180 nights |
| Custodial Parent Status | Yes | No |
| Default Right to Claim Credit | Yes | No with Form 8332 only |
| Income | $80,000 | $95,000 |
| Phase-Out Applies | No | No |
| Credit Amount If Claimed | $2,200 | $2,200 (if Form 8332 signed) |
Lisa is the custodial parent because their son lived with her for more nights. She has the default right to claim the child as a dependent and take the Child Tax Credit. Robert cannot claim the credit unless Lisa signs Form 8332, releasing her claim to the dependency exemption.
If Lisa signs Form 8332, Robert can claim the Child Tax Credit. However, Lisa retains the right to claim the Earned Income Tax Credit and Head of Household filing status because Form 8332 does not transfer those benefits. The custodial parent always keeps certain tax benefits regardless of who claims the dependency exemption.
Form 8332: Transferring the Credit Between Parents
Form 8332 is titled “Release/Revocation of Release of Claim to Exemption for Child by Custodial Parent.” The custodial parent uses this form to transfer the right to claim the dependency exemption to the noncustodial parent. When properly executed, this form allows the noncustodial parent to claim the Child Tax Credit.
The custodial parent is the parent with whom the child lived for the greater number of nights during the year. If the child lived with each parent for an equal number of nights, the parent with the higher adjusted gross income is the custodial parent. These rules apply even if the parents have a written custody agreement stating otherwise.
The custodial parent must sign and date Form 8332. The form allows the custodial parent to release the claim for the current year only (Part I) or for future years (Part II). If releasing for future years, the custodial parent must specify which years or state “all future years.”
The noncustodial parent must attach the signed Form 8332 to their tax return every year they claim the credit. A copy of a divorce decree or separation agreement generally does not substitute for Form 8332 unless the decree or agreement was executed before 2009 and meets specific requirements. Even then, the noncustodial parent must attach the relevant pages of the decree to their return.
Form 8332 transfers only certain tax benefits. The noncustodial parent can claim the child as a dependent, the Child Tax Credit, the Additional Child Tax Credit, and the Credit for Other Dependents. The custodial parent retains the right to claim Head of Household filing status, the Earned Income Tax Credit, the Child and Dependent Care Credit, and exclusion for dependent care benefits.
The custodial parent can revoke a previous release by completing Part III of Form 8332. The custodial parent must provide written notice to the noncustodial parent by the earlier of the due date of the noncustodial parent’s return or the date the noncustodial parent files. The custodial parent must attach the revocation to their tax return for the year they reclaim the exemption.
| Tax Benefit | Can Be Transferred with Form 8332 | Cannot Be Transferred (Custodial Parent Only) |
|---|---|---|
| Dependency Exemption | ✓ | |
| Child Tax Credit | ✓ | |
| Additional Child Tax Credit | ✓ | |
| Credit for Other Dependents | ✓ | |
| Earned Income Tax Credit | ✓ | |
| Child and Dependent Care Credit | ✓ | |
| Head of Household Filing Status | ✓ | |
| Dependent Care Flexible Spending | ✓ |
How to Claim the Child Tax Credit
You claim the Child Tax Credit by filing Form 1040 or Form 1040-SR and completing Schedule 8812. The process requires you to list your qualifying children in the Dependents section of Form 1040 and check the box indicating each child qualifies for the Child Tax Credit.
List each qualifying child’s name, Social Security Number, relationship to you, and check the appropriate box in the Dependents section. The IRS will deny your credit if the child’s SSN is missing, incorrect, or invalid. Make sure the name on your tax return exactly matches the name on the child’s Social Security card.
Complete Schedule 8812 to calculate your credit amount. Part I calculates the Child Tax Credit and Credit for Other Dependents. You enter the number of qualifying children, multiply by $2,200, and enter the result. You then apply any phase-out reduction based on your income.
Part II-A of Schedule 8812 calculates the Additional Child Tax Credit for most people. You enter your earned income and follow the worksheet to determine your refundable credit. Part II-B provides an alternate calculation for taxpayers with three or more qualifying children using Social Security taxes.
Attach Schedule 8812 to your Form 1040 when you file. If you file electronically, the software will automatically attach the schedule. If you file by paper, make sure to include the schedule or the IRS will reject your credit claim and delay your refund.
The IRS processes returns claiming the Additional Child Tax Credit more slowly. Federal law prohibits the IRS from issuing ACTC refunds before mid-February, even if you file in January. This delay allows the IRS to verify information and prevent fraud.
If the IRS previously denied or reduced your claim for the Child Tax Credit, you may need to file Form 8862. This form recertifies your eligibility after a disallowed claim. You must complete Form 8862 and attach it to your tax return before you can claim the credit again.
Documentation You Need to Claim the Credit
The IRS does not require you to submit documentation when you file your return. However, you must keep records proving your child’s eligibility in case the IRS audits your return. The IRS can audit your return up to three years after you file, so maintain these records for at least three years.
Essential documents include your child’s Social Security card or Social Security Number verification letter. The number on the card must match the number you enter on your tax return exactly. Any mismatch will result in a denied credit and possible audit.
Keep proof of your child’s relationship to you. Birth certificates, adoption papers, court documents for foster placement, or other official records establish the relationship. If the child is your grandchild, niece, or nephew, you need documentation showing both your relationship to the child’s parent and the parent’s relationship to the child.
Maintain proof that your child lived with you for more than half the year. School records showing your address, medical records, childcare provider statements, and other documents with dates and addresses establish residency. The IRS particularly scrutinizes the residency requirement during audits.
Keep copies of documents supporting the custody arrangement if you are divorced or separated. The divorce decree, separation agreement, custody order, and signed Form 8332 are essential if the noncustodial parent claims the credit. Both parents should keep copies of these documents in case the IRS questions either return.
Maintain records of financial support you provided. Receipts for food, housing, clothing, medical care, education, and other expenses help prove you provided more than half the child’s support. While you generally do not need to submit these records with your return, they become essential if the IRS questions your claim.
Mistakes to Avoid When Claiming the Child Tax Credit
Understanding common errors helps you avoid denied claims, delayed refunds, and potential penalties. The IRS reports that most errors involve incorrect age, missing Social Security Numbers, or residency problems. Each mistake has specific consequences that affect your refund and future claims.
Filing without a Social Security Number. Many parents file their tax return before their newborn receives an SSN. The IRS will deny the credit if you do not include a valid SSN issued before your return due date. The consequence is complete loss of the credit for that child for that year with no way to fix the problem after you file. Instead, apply for your baby’s SSN in the hospital when completing the birth certificate, then wait one to six weeks before filing your return. If you cannot obtain the SSN by the April deadline, file for an extension to delay your return until October.
Claiming a child who turns 17 before year-end. The IRS denies credits for children who are 17 or older on December 31. Many parents incorrectly believe that if their child was 16 for most of the year, they qualify for the credit. The consequence is a denied credit, a bill for taxes owed plus interest, and potential penalties if the IRS determines the error was reckless or intentional. Instead, check your child’s age on December 31, not their age when you file. If your child is 17 on that date, claim the Credit for Other Dependents instead of the Child Tax Credit.
Failing to meet the residency test. Children in split custody situations must live with you for more than 183 days, not exactly 183 days. Some taxpayers incorrectly believe that exactly half the year is sufficient. The consequence is the IRS will deny the credit and may assess the credit to the other parent if both parents claim the same child. Instead, count the nights carefully and maintain documentation showing your child spent at least 184 nights in your home (185 in leap years).
Not understanding Modified Adjusted Gross Income. Many high earners do not realize that certain exclusions add back to their AGI to calculate MAGI. Taxpayers working abroad who exclude foreign earned income often exceed the threshold when the exclusion is added back. The consequence is claiming too much credit, owing additional tax when the IRS corrects the error, plus interest and potential penalties. Instead, calculate your MAGI by adding back the foreign earned income exclusion, foreign housing exclusion, and other items specified in the IRS instructions before determining your credit amount.
Claiming a child with an ITIN instead of an SSN. Starting in 2025, children must have valid Social Security Numbers, not Individual Taxpayer Identification Numbers. Parents of children who previously qualified with ITINs now find those children ineligible. The consequence is losing the $2,200 credit and possibly owing money if you received advance payments. Instead, apply for a Social Security Number if your child is eligible, or claim the Credit for Other Dependents (which accepts ITINs) worth $500 instead of the $2,200 Child Tax Credit.
Both parents claiming the same child. When divorced parents both attempt to claim the credit, the IRS holds both refunds and requires both parents to provide documentation. The taxpayer who loses the dispute must repay the credit plus interest and may face a two-year ban from claiming the credit. The consequence includes delayed refunds for both parents, extensive documentation requirements, and potential penalties. Instead, the custodial parent should either claim the credit or properly complete Form 8332 to release the claim to the noncustodial parent before either parent files.
Ignoring the earned income requirement for ACTC. Many people with investment income incorrectly believe that all income counts toward the $2,500 earned income threshold. Interest, dividends, capital gains, unemployment, and Social Security benefits do not count as earned income. The consequence is claiming a refundable credit you do not qualify for, resulting in repayment with interest and possible penalties. Instead, calculate only your wages, salaries, tips, self-employment income, and certain disability payments when determining if you meet the $2,500 threshold.
Failing to file Form 8862 after a denied claim. If the IRS previously denied your credit, you cannot claim it again until you file Form 8862 to recertify your eligibility. Many taxpayers do not know about this requirement and wonder why the IRS denies their credit year after year. The consequence is automatic denial of your credit every year until you file Form 8862, causing you to lose thousands of dollars. Instead, carefully read any IRS notices about denied credits and complete Form 8862 when instructed, attaching it to your next tax return.
Do’s and Don’ts for the Child Tax Credit
Following these guidelines helps you maximize your credit, avoid errors, and prevent IRS problems. Each recommendation addresses common situations taxpayers face when claiming the credit.
Do’s
Do verify your child’s Social Security Number. Compare the number on your child’s Social Security card to what you enter on your tax return character by character. One wrong digit causes the IRS to deny your credit automatically. This verification takes less than one minute but prevents months of delayed refunds and IRS correspondence. If your child’s name legally changed due to adoption or marriage, update the Social Security Administration records before filing your return.
Do calculate the number of nights carefully. Create a calendar showing which parent the child slept with each night of the year. Count carefully because the parent with more nights has priority to claim the credit. Temporary absences for school, vacation, medical care, or detention count as nights with the parent who has custody during that period. Keep this calendar with your tax records as proof if the IRS questions your claim.
Do file Form 8332 if you are the noncustodial parent. Obtain a signed Form 8332 from the custodial parent before you file your return. Attach the original signed form to your paper return or upload it with your electronic return. Keep a copy for your records because you must attach Form 8332 to your return every year you claim the credit, even if the custodial parent released future years. A text message or email from the other parent is not sufficient; only the official form works.
Do use tax software or a professional preparer. The Child Tax Credit rules are complex, with eight separate qualification tests and multiple calculation steps. Tax software includes built-in error checks that catch common mistakes before you file. Professional preparers know the rules and can help you determine eligibility, especially in complicated situations involving divorce, split custody, or high income. The software or preparer fee is far less than the cost of losing the credit or paying penalties.
Do file for an extension if you are missing documentation. If you do not have your child’s Social Security Number by the April deadline, file Form 4868 to extend your return until October. This six-month extension gives you time to obtain the SSN while avoiding the credit denial that occurs when you file without it. Remember that an extension to file is not an extension to pay; you must estimate and pay any taxes owed by April to avoid penalties.
Do save all documentation for at least three years. The IRS can audit your return up to three years after you file. Maintain birth certificates, Social Security cards, school records, medical records, custody agreements, and any other documents proving your child meets all qualification tests. Organize these documents in a folder labeled with the tax year. If the IRS questions your credit, you can provide documentation quickly, avoiding delays and potential credit denials.
Don’ts
Don’t claim a child who fails any of the eight tests. All eight qualification requirements must be met. If your child fails even one test, you cannot claim the credit. Claiming a credit when you do not qualify results in penalties, interest, and possible bans on future credit claims. Instead, determine whether your dependent qualifies for the Credit for Other Dependents worth $500, which has different requirements.
Don’t assume your divorce decree transfers the credit. Court orders and divorce decrees do not automatically give the noncustodial parent the right to claim the credit. Only Form 8332 transfers the credit, regardless of what your divorce decree says. Many taxpayers lose credits or face audits because they relied on their decree instead of filing Form 8332. If you are the noncustodial parent, obtain a signed Form 8332 before filing, even if your decree says you can claim the child.
Don’t file a joint return with your spouse if that disqualifies your child. Some 19- to 24-year-old children file joint returns with their spouses. When they do, their parents cannot claim them as dependents unless the child filed the joint return only to claim a refund of withheld taxes. If your married child owes tax on their joint return, you cannot claim them as a dependent or take any credit for them. Plan carefully with your child to determine the best overall tax strategy.
Don’t claim the credit if you used Married Filing Separately. Starting in 2025, taxpayers filing with Married Filing Separately status cannot claim the Child Tax Credit. The One Big Beautiful Bill Act eliminated this option because many taxpayers incorrectly used this filing status. If you and your spouse live together, you must file jointly to claim the credit. If you are legally separated or live apart, you may qualify for Head of Household status instead, which allows the credit.
Don’t ignore IRS notices. If the IRS sends you a notice questioning your credit, respond by the deadline shown on the notice. Ignoring an audit letter results in automatic denial of your credit, repayment demands, and potential penalties. The IRS notice will explain what documentation you need to provide. Gather the requested documents and mail or upload them according to the notice instructions. If you need more time, call the IRS at the number on the notice to request an extension.
Don’t pay someone who promises an unusually large refund. Some tax preparers promise inflated refunds by incorrectly claiming credits you do not qualify for. This is tax fraud, and you remain responsible for the incorrect return even if a preparer filed it. The IRS will assess penalties against you, not the preparer. Choose a reputable preparer with credentials such as CPA, Enrolled Agent, or tax attorney. Avoid preparers who base their fee on your refund amount or who refuse to sign your return.
Don’t wait until the last minute to file. Returns filed in January or early February often experience faster processing and fewer errors. Filing early also helps you discover problems while you still have time to fix them. If the IRS questions your return, you have more time to respond before the April deadline. Additionally, filing early reduces your risk of tax refund identity theft because the IRS has your return on file before a criminal can submit a fraudulent one.
State Child Tax Credits
Some states offer their own child tax credits in addition to the federal credit. These state credits provide extra money to families with children. The rules, amounts, and eligibility requirements vary significantly by state.
As of 2025, fifteen states offer child tax credits. Eleven of these states offer refundable credits, meaning you can receive money back even if you owe no state tax. Four states offer nonrefundable credits that can only reduce your state tax to zero.
New York recently expanded its Empire State Child Credit. For 2025, New York provides $1,000 per child under age 4 and $330 per child ages 4 through 16. Starting in 2026, the credit increases to $1,000 per child under age 4 and $500 per child ages 4 through 16. The credit phases out for higher-income families earning more than $110,000 (joint filers) or $75,000 (single filers).
California offers the Young Child Tax Credit for children under age 6. Colorado provides a refundable credit equal to a percentage of the federal credit. Idaho, Maine, Maryland, Massachusetts, Minnesota, New Mexico, Oklahoma, Oregon, Utah, and Vermont also have state child tax credits with varying amounts and requirements.
State credits often have different qualification requirements than the federal credit. Some states allow older children to qualify. Some states base the credit on a percentage of the federal credit. Others provide a flat dollar amount per child. You must review your state’s specific rules to determine eligibility.
You claim state child tax credits on your state income tax return, not your federal return. The state credit is separate from the federal credit. Receiving a federal credit does not automatically give you a state credit. You must separately qualify under your state’s rules and claim the credit on the appropriate state form.
Check your state’s tax agency website for current information about child tax credits. States frequently change their credit amounts, phase-out thresholds, and eligibility rules. Some state credits are temporary and expire unless the legislature extends them. Your state may have enacted new credits or expanded existing ones since this article was published.
Penalties for Incorrect Claims
The IRS imposes penalties when you incorrectly claim the Child Tax Credit. These penalties range from minor accuracy-related penalties to severe fraud penalties. Understanding the penalties helps you avoid costly mistakes.
The Erroneous Claim for Refund or Credit penalty applies when you claim an excessive amount without reasonable cause. Under IRC Section 6676, the IRS assesses a penalty equal to 20 percent of the excessive amount. If you claim a $2,200 credit you do not qualify for, the penalty is $440 plus interest on the unpaid tax.
If the IRS determines your error was due to negligence or disregard of rules, you face an accuracy-related penalty under IRC Section 6662. This penalty equals 20 percent of the underpayment of tax. Negligence means you did not make a reasonable attempt to comply with the tax law or did not keep adequate records.
The IRS can ban you from claiming the Child Tax Credit for two to ten years. If you recklessly or intentionally disregard the rules, the IRS bans you for two years. If you fraudulently claim the credit, the ban extends to ten years. During the ban period, you cannot claim the credit even if you have qualifying children.
You must also repay the credit plus interest. The IRS calculates interest from the original return due date until you repay the amount. Interest rates change quarterly. As of 2025, the IRS interest rate is approximately 8 percent annually, though the rate fluctuates based on federal short-term rates.
The IRS pursues criminal prosecution in extreme cases. Tax fraud is a felony under IRC Section 7206. If convicted, you face fines up to $250,000 and imprisonment up to three years. The IRS typically reserves criminal prosecution for large fraudulent claims, repeated violations, or situations involving false documents.
If you made an honest mistake, respond promptly to IRS notices and cooperate with the audit. The IRS is more likely to waive penalties if you show reasonable cause for the error. Reasonable cause includes relying on incorrect advice from a tax professional, serious illness, death of a family member, or unavoidable absence when records were destroyed.
What Happens If You Don’t Claim the Credit
You do not face penalties for failing to claim the Child Tax Credit. The IRS does not care if you voluntarily forfeit tax credits you qualify for. However, you lose significant money that you are entitled to receive.
For a family with two children, the credit is worth $4,400. Missing this credit means paying $4,400 more in federal tax than necessary. For families with low income who qualify for the Additional Child Tax Credit, the loss is even greater because they miss out on a refund.
You can amend your tax return to claim the credit if you discover you qualified but did not claim it. File Form 1040-X, Amended U.S. Individual Income Tax Return, to correct your original return. The IRS allows you to amend returns for up to three years after the original filing deadline or two years after you paid the tax, whichever is later.
For example, if you filed your 2023 return by April 15, 2024, you have until April 15, 2027, to file an amended return claiming the credit. If you file an amended return, the IRS will process it and send you a refund check for the additional credit amount.
Some taxpayers intentionally choose not to claim a child to allow the child to claim education credits. If your income is too high to benefit from the American Opportunity Tax Credit, and your child has enough income to use the credit, it may make sense to not claim the child as your dependent. This strategy requires careful tax planning to determine the overall benefit.
Many low-income families do not file tax returns because they earned too little to owe tax. These families miss out on thousands of dollars in refundable credits. The IRS estimates that approximately 20 percent of eligible taxpayers do not claim the Earned Income Tax Credit and Child Tax Credit because they do not file returns.
Free tax preparation services help low-income families claim credits they qualify for. The Volunteer Income Tax Assistance (VITA) program provides free tax return preparation at community centers, libraries, and schools. IRS-certified volunteers prepare returns and help families claim all credits they qualify for.
