Yes, you can usually claim your child as a dependent when they receive Social Security, but the benefits create one specific problem you have to plan around: money your child spends on their own living expenses counts as support they provided for themselves, and if that figure climbs past half of their total support, the dependency claim collapses. The type of benefit, how the money is used, and which dependency test you’re relying on all shape the answer.
Why the Support Test Is the Real Hurdle
The IRS treats Social Security benefits that a child spends on their own living expenses as support the child provided for themselves.1Internal Revenue Service. Publication 501 (2025), Dependents, Standard Deduction, and Filing Information – Section: Support Test (To Be a Qualifying Relative) Total support covers food, housing, clothing, education, medical and dental care, recreation, and transportation from every source. You add the whole year’s spending together and then look at who paid for what.
The threshold depends on which dependency path applies. For a qualifying child, the child’s own contributions just have to stay at or below half. For a qualifying relative, your contributions have to exceed half.
A concrete example shows how fast benefits sink the claim. Your child receives $1,200 a month in SSDI, $14,400 for the year, and spends all of it on rent, food, and personal expenses. Total support costs come to $24,000. The child covered $14,400, which is 60%. You covered $9,600, which is 40%. Both versions of the support test fail. The child provided more than half their own support, so they aren’t a qualifying child. You provided less than half, so they aren’t a qualifying relative either.
Save the Benefits, Pass the Test
The fix is simple to describe and takes discipline to execute: keep the Social Security benefits out of current spending. Only money actually spent on living expenses counts in the support calculation. Benefits deposited into a savings account, investment account, or ABLE account aren’t treated as support the child provided for themselves.
Run the same numbers with the benefits parked instead of spent. The $14,400 goes straight into savings. You pay the full $24,000 in living expenses from your own income. The child’s contribution to their own support is $0. Yours is 100%. Both support tests pass with room to spare.
Documentation is what makes this hold up. Keep bank statements showing the Social Security deposits landing in a separate account. Track your own spending on housing, food, medical care, and the rest. If the IRS asks, you need a clean paper trail showing the benefits stayed in savings while your money covered the bills.
An ABLE account is often the better place to put the money if your child has a qualifying disability. Achieving Better Life Experience accounts work like 529 plans but are built for people whose disability began before age 46. In 2026, up to $20,000 can be contributed annually, funds grow tax-free, and withdrawals for qualified disability expenses, including housing, education, transportation, health care, and personal support services, come out tax-free as well.2Internal Revenue Service. ABLE Accounts Can Help People with Disabilities Pay for Disability-Related Expenses For dependency purposes, routing benefits into an ABLE account does the same job as a regular savings account, with the added advantage of favorable treatment under SSI resource limits.
The Representative Payee Complication
If you’re your child’s representative payee, you can’t simply divert every benefit check into savings. The Social Security Administration requires that benefits go first toward day-to-day needs for food and shelter, then toward medical and dental expenses not covered by insurance, then toward personal needs like clothing and recreation. Only leftover funds after those priorities are met should be saved.3Social Security Administration. A Guide for Representative Payees
That rule bumps against the tax strategy of saving everything. In practice, many families cover most expenses out of their own income and use the benefits mainly for savings, but the SSA’s priorities can’t be ignored. Keep records showing the child’s basic needs are being met and that any saved funds are genuinely surplus.
Which Dependency Path Fits Your Child
The IRS recognizes two categories of dependents, and your child needs to meet all the requirements of at least one.
Qualifying Child
This is the easier path and the one that unlocks the biggest credits. A qualifying child must meet tests for relationship, age, residency, support, and joint return filing. The age test says the child must be under 19 at year-end, or under 24 if a full-time student. A child who is permanently and totally disabled qualifies at any age. The child must live with you more than half the year and must not file a joint return except to claim a refund of withheld taxes.4Internal Revenue Service. Dependents
There’s no gross income test for a qualifying child, so the amount of Social Security a child receives doesn’t matter for that part of the analysis. The support test is also the easier version: the child just can’t provide more than half of their own support.
Qualifying Relative
If your child fails the qualifying child tests, usually because of age, qualifying relative is the fallback. The requirements tighten in two ways. The child’s gross income must stay below a set threshold, which is $5,200 for the 2025 tax year and adjusted annually for inflation.5Internal Revenue Service. Publication 501 (2025), Dependents, Standard Deduction, and Filing Information And you must provide more than half of the child’s total support, which is a stricter version of the same support test.
The Disability Exception
For a child with a permanent and total disability, the age test for qualifying child status is waived entirely. A 35-year-old disabled child living with you can still be your qualifying child if the other tests are met.6Office of the Law Revision Counsel. 26 USC 152 – Dependent Defined The IRS defines permanent and total disability as the inability to engage in any substantial gainful activity due to a physical or mental condition that has lasted or is expected to last at least 12 continuous months, or is expected to result in death.7Internal Revenue Service. Publication 524 (2023), Credit for the Elderly or the Disabled
If the qualifying relative path is the only one open, income earned at a sheltered workshop doesn’t count toward the gross income threshold, as long as the person is there primarily for medical care and the income comes from activities connected to that care.6Office of the Law Revision Counsel. 26 USC 152 – Dependent Defined The support test, though, still applies in full. Benefits spent on living expenses still count as self-support.
SSI, SSDI, and the Gross Income Test
Before running numbers, identify which benefit your child receives, because the tax treatment is not the same. Supplemental Security Income (SSI) is a needs-based program and the payments are not taxable income. SSI never counts toward the gross income test in any context. Social Security Disability Insurance (SSDI) and survivor benefits are earned benefits based on a worker’s record, and they can become partially taxable if the child has enough other income.
For most children, SSDI and survivor benefits aren’t taxable at all. Taxability turns on provisional income: half the child’s Social Security benefits plus all other income, including tax-exempt interest. For a single filer, none of the benefits become taxable unless provisional income tops $25,000.8Internal Revenue Service. Social Security Income A child receiving $14,000 a year in survivor benefits with no other income has provisional income of $7,000, far below the threshold, so zero dollars count toward the gross income test.
The gross income test only matters for a qualifying relative, not a qualifying child. It becomes a real problem only when a child has significant wages, investment income, or other taxable income alongside the Social Security.
For the support test, both SSI and SSDI count as the child’s own support if spent on living expenses. The savings strategy works the same way for either program.
What the Dependency Claim Is Worth
The reason this analysis matters is the dollar value of the credits tied to claiming a child as a dependent.
The Child Tax Credit for the 2025 tax year is worth up to $2,200 per qualifying child, with up to $1,700 of that refundable. The child must be 17 or younger at year-end and must be claimed as a dependent who passes the qualifying child test.9Internal Revenue Service. Child Tax Credit The credit begins phasing out at $200,000 in modified adjusted gross income for single and head-of-household filers and $400,000 for married couples filing jointly.
If your child doesn’t qualify for the CTC, either because they’re over 17 or because they only pass the qualifying relative test, you can still claim the Credit for Other Dependents. That credit is nonrefundable and worth up to $500 per dependent.
An adult disabled child who qualifies as your qualifying child through the disability age waiver is eligible for the full Child Tax Credit, not just the smaller Credit for Other Dependents. That difference is why the qualifying child path matters so much for families with disabled dependents.
A Caveat if You Invest the Saved Benefits
If you save the child’s Social Security money by investing it, the investment returns can trigger the kiddie tax. When a dependent child’s unearned income (interest, dividends, and capital gains) exceeds $2,700, the excess is taxed at the parent’s marginal rate instead of the child’s lower rate.10Internal Revenue Service. Topic No. 553, Tax on a Child’s Investment and Other Unearned Income (Kiddie Tax) The taxable portion of Social Security benefits itself counts as unearned income for this purpose.11Internal Revenue Service. Instructions for Form 8615 (2025) – Tax for Certain Children Who Have Unearned Income
The kiddie tax doesn’t undermine the dependency claim itself, but it can erode the tax benefit of saving the benefits in a taxable brokerage account. ABLE accounts avoid the problem because their earnings grow tax-free. A regular savings account generating modest interest is unlikely to cross $2,700, but a brokerage account with years of accumulated benefits could.
