Can I Claim My Child as a Dependent If They Work?

Yes, you can claim your child as a dependent if they work. Federal tax law sets no income cap that automatically disqualifies a working child from being your dependent. What matters is the support test: if your child did not pay for more than half of their own living expenses during the year, you can generally still claim them, no matter what their paycheck looked like.

The Support Test Is What Actually Governs

The support test is the rule that decides most of these situations. It asks one question: did your child pay for more than half of their own support during the year?¹ If the answer is no, your child passes the test, and their wages are not the deciding factor.

“Support” means the real cost of keeping your child housed, fed, clothed, educated, and healthy. When you tally up what you provided, count the fair rental value of the room in your home, not just the cash you spent on housing. Health insurance premiums you pay on your child’s behalf count as support you provided.² Tuition, school supplies, car insurance, groceries, and clothing all belong in the calculation.

Here is the detail that makes the test easier to pass than most parents expect. Money your child earns but does not spend on their own living expenses is not counted as self-support. If your teenager makes $8,000 over the summer and puts most of it into savings, only the portion they actually spent on their own food, clothing, transportation, or other needs goes on their side of the ledger.³ A working child can build a real bank balance and still be your dependent, as long as you are still covering the majority of their day-to-day costs.

The Other Tests Your Child Still Has To Pass

A “qualifying child” has to clear a few other rules alongside the support test. The child must be your son, daughter, stepchild, foster child, or a descendant of one of them, such as a grandchild. They must live with you for more than half the year, and temporary absences for college, camp, or vacation still count as living with you.¹ They must also be younger than you (or your spouse, on a joint return).⁴

The age test draws firm lines. Your child must be under 19 at the end of the tax year, or under 24 if they are a full-time student.¹ A full-time student is someone enrolled full-time at a school with a regular faculty and curriculum for at least five months of the year.⁵ There is no age limit for a child who is permanently and totally disabled, meaning a physical or mental condition prevents them from working and is expected to last at least 12 continuous months or result in death.⁶

One more restriction: your child cannot have filed a joint return with a spouse for the year, unless that return was filed only to claim a refund.¹

Older Working Children: A Different Test With an Income Cap

Once your child ages out of the qualifying child rules, usually by turning 24 and leaving school, or turning 19 without being a student, they may still be claimable as a “qualifying relative.” This is where an income limit actually appears.¹

For a qualifying relative, the person’s gross income for the year must fall below a threshold the IRS adjusts annually. For the 2025 tax year, that limit was $5,200.³ Even a dollar over disqualifies them, no matter how much you provide. You must also pay more than half of their total support for the year, and this version looks at every source of support, not just what the child spent on themselves. In practice, this route works for adult children who are unemployed or working very little while you continue to cover their expenses.

What You Get by Claiming a Working Child

Claiming your child changes what tax credits you can take. The benefit depends on their age at year-end.

Child Tax Credit for a child under 17: up to $2,200 per child, with up to $1,700 refundable, meaning you can receive it even if you owe no federal income tax.⁷
Credit for Other Dependents for a child 17 or older who doesn’t qualify for the Child Tax Credit: a $500 nonrefundable credit.⁷

Both credits begin to phase out once your adjusted gross income exceeds $200,000, or $400,000 for married couples filing jointly.⁷

Your Child Can Still File Their Own Return

Your child filing a tax return does not stop you from claiming them. Both returns can happen in the same year. When your child files, they need to indicate on their Form 1040 that someone else can claim them as a dependent.⁸ If they miss that step, the IRS may flag both returns.

Being claimed also changes how your child’s standard deduction is calculated. Instead of the full single-filer standard deduction ($16,100 in 2026), a dependent’s deduction is limited to the greater of a set minimum or their earned income plus a small fixed addition, capped at the full single-filer amount.⁹¹⁰ For a child earning a few thousand dollars at a part-time job, withholding often exceeds their actual tax, and filing lets them recover the difference as a refund without affecting your claim.

Gig Work Has Its Own Filing Trigger

Children earning money through freelancing, ride-share driving, reselling online, or other independent work face a rule that doesn’t apply to W-2 jobs. If your child’s net self-employment earnings reach $400 or more, they must file a return and pay self-employment tax, even if their total income is well under the normal filing threshold.¹¹ They report the income on Schedule C and calculate the tax on Schedule SE. This obligation exists regardless of age and regardless of whether you claim them. The gig income itself does not disqualify your child; only the support test decides that.

Investment Income and the Kiddie Tax

If your child has investment income, a separate set of rules kicks in. When a dependent child’s unearned income (interest, dividends, capital gains) exceeds $2,700, the excess is taxed at the parent’s marginal rate rather than the child’s.¹² This is the “kiddie tax,” and it applies to children under 19, or full-time students under 24, who cross the threshold. It doesn’t change whether you can claim your child. It changes how much tax your child owes on that investment income, reported on Form 8615.

If You Get the Claim Wrong

If the IRS later decides your child didn’t qualify (for example, because they actually paid for more than half of their own support) you’ll owe the extra tax plus interest. The IRS can also add an accuracy-related penalty of 20% of the underpayment if the error is treated as negligence or a substantial understatement.¹³

Keep records. Save receipts for tuition, health insurance premiums, housing costs, and other major expenses you cover. If your child works, keep a rough tally of what they spent on themselves versus what they saved.
