Tax breaks for dependents: the documents parents need for each credit
By Arthur Teboul, DokuTrak · Published
In brief
Tax deductions for dependents are mostly credits: the child tax credit, the credit for other dependents and the child and dependent care credit. Each one rests on documents: a valid SSN for each child, proof the child lived with you, and the care provider’s name, address and tax ID.

Tax deductions for dependents, and the papers behind each
Children cut your tax mainly through credits, not deductions. A credit is an amount taken off the tax itself, which is worth more than a deduction of the same size. Each credit asks for its own proof, so it pays to sort the papers by credit before you send them.
The table shows what each break is worth for 2025, the two care rules that change for 2026, and the document a preparer will ask for first. The sections below explain the tests that each document proves.
| Break | What it is worth | First document to gather |
|---|---|---|
| Child tax credit | 2025: up to $2,200 per child (IRS, Child Tax Credit) | Each child’s Social Security card |
| Refundable part of the child credit | 2025: up to $1,700 per child (IRS, Child Tax Credit) | Your Forms W-2 or other earned income records |
| Credit for other dependents | 2025: up to $500 each (IRS, Child Tax Credit) | SSN, ITIN or ATIN for the dependent |
| Child and dependent care credit | 2025: up to 35% of care costs (IRS Publication 503); 2026: rate starts at 50% (26 U.S.C. 21) | Provider name, address and tax ID |
| Dependent care benefits from work | 2025: up to $5,000 excluded (IRS Publication 503); 2026: up to $7,500 (26 U.S.C. 129) | Form W-2, Box 10 |
The child tax credit and the SSN rule
For the 2025 tax year, a qualifying child for this credit must be under 17 at the end of the year (IRS, Child Tax Credit). The child must also be your son, daughter, stepchild, sibling or a descendant of one, and must have lived with you for more than half the year (IRS Publication 501).
The SSN rule now reaches the parents too. You, or your spouse on a joint return, and each child must have an SSN valid for work and issued before the return’s due date (IRS, Child Tax Credit). A child with only an ITIN or an adoption ID cannot get the child tax credit, but can still count for the credit for other dependents (IRS, Child Tax Credit).
So the first request is simple: a clear copy of each Social Security card, with names that match. A newborn’s card can take weeks to arrive, so apply at the hospital and keep the receipt. The Social Security card guide lists which copies a preparer accepts.
Proving the relationship and where the child lived
A qualifying child is a child who passes the relationship, age, residency and support tests for you (IRS Publication 501). The age test is under 19, or under 24 for a full-time student, or any age if permanently and totally disabled (IRS Publication 501). Older children who fail it may still be a qualifying relative.
The relationship comes from a birth certificate, an adoption decree, or the placement papers for a child placed with you by an authorized agency. Residency comes from records with the child’s name and your address, such as school enrollment letters, medical bills or a lease that lists household members. Keep at least two for each child.
If the child works, add their own Forms W-2 or 1099. Their earnings help show who paid the child’s support. A child who provided more than half of their own support is not your qualifying child (IRS Publication 501). The gross income test applies only to a qualifying relative, so a student under 24 can earn any amount and stay your qualifying child if that support test holds (IRS Publication 501).
A working teen may still file to get withholding back. On their own 2025 return, a dependent’s standard deduction is the larger of $1,350 or earned income plus $450, capped at $15,750 (IRS Publication 501). For example, a 16-year-old with a $6,000 summer W-2 gets a $6,450 standard deduction, so no income tax is due on that pay (IRS Publication 501).
Divorced or separated parents: Form 8332
Only one parent can claim a child in a year. The custodial parent is the parent the child lived with for more nights during the year, and that parent claims the child by default. A custodial parent can use Form 8332 to release the claim so the other parent can claim the child (About Form 8332). The same form revokes an earlier release (About Form 8332).
The noncustodial parent attaches the signed release to their return (IRS Publication 501). Bring the signed Form 8332, the custody pages of the decree, and last year’s return to show who claimed each child. A mismatch between two parents’ returns is a common reason for an IRS letter, so settle it before filing.
Child care costs for Form 2441
The care credit covers care for a dependent under age 13, paid so you can work or look for work (IRS Publication 503). For 2025 the cost limit is $3,000 for one child or $6,000 for two or more (IRS Publication 503). Day camp can count, but overnight camp does not (IRS Publication 503).
Two rules change for 2026 care. The credit rate starts at 50% of costs, then steps down to 35% and, above $75,000 of AGI or $150,000 joint, toward 20% (26 U.S.C. 21). And an employer dependent care account can cover up to $7,500 tax-free, or $3,750 on a separate return (26 U.S.C. 129). If you raise your election for 2026, ask the provider for a statement that matches the larger claims.
Each provider must be named on the return with an address and a tax ID. Ask for it at the start of the year, before the last payment. If your employer ran a dependent care account, the amount shows in Box 10 of your W-2, and it lowers the costs you can count (IRS Publication 503).
Keep the invoices by child. For example, a daycare statement for a toddler and summer day camp receipts for an older child go in two piles.
College, adoption and the new Trump account
Older dependents bring their own forms. A college student brings Form 1098-T, and any withdrawal from a college savings plan comes with Form 1099-Q. If you adopted, keep the final decree and the receipts for fees and travel for Form 8839.
For children born after 2024 and before 2029, parents can open a Trump account on Form 4547 and elect a $1,000 pilot contribution (IRS Publication 503). The form can be filed with your 2025 return (IRS Publication 503). Bring the child’s SSN card and birth certificate if you plan to make that election.
Questions people ask
What are the requirements to claim a dependent?
A qualifying child must pass the relationship, age, residency and support tests; a qualifying relative must have gross income under $5,200 for 2025 and get more than half their support from you (IRS Publication 501).
Does my child need a Social Security number for the child tax credit?
Yes. Each child, and you or your spouse on a joint return, needs an SSN valid for work issued before the return due date (IRS, Child Tax Credit). A child with an ITIN may still qualify for the $500 credit for other dependents (IRS, Child Tax Credit).
Which parent claims the child after a divorce?
The custodial parent, unless they sign Form 8332 to release the claim to the other parent (About Form 8332). The noncustodial parent then attaches that release to their return (IRS Publication 501).
Can I claim my mother or father on the same return as my kids?
Yes, as a qualifying relative, even if they live elsewhere, when you pay over half their support and their gross income is under $5,200 for 2025 (IRS Publication 501). A parent brings the $500 credit for other dependents, not the child tax credit (IRS, Child Tax Credit).
What do I need for the child and dependent care credit?
The provider’s name, address and tax ID, the amount paid per child, and any dependent care benefits from your employer (IRS Publication 503). The care must let you work or look for work (IRS Publication 503).
