Social Security benefits paid on behalf of your child belong to your child for tax purposes, so if anything needs to be reported, it goes on a return in your child’s name and Social Security number, not on yours. In most cases, though, nothing needs to be reported at all: a child whose only income is Social Security almost never owes federal income tax, and usually is not required to file a return. Here is how to work through it.
Whose Return the Benefits Go On
IRS Publication 915 says Social Security benefits are taxable to “the person who has the legal right to receive the benefits.” When a child qualifies for dependent or survivor benefits, that person is the child. You may cash the checks as representative payee, but the money is your child’s income for tax purposes.1Internal Revenue Service. Publication 915 (2025), Social Security and Equivalent Railroad Retirement Benefits
The Social Security Administration confirms this by issuing Form SSA-1099 in your child’s name and Social Security number. That form is the starting document for any reporting. Adding your child’s benefits to your own Form 1040 would inflate your adjusted gross income and could push more of your own Social Security into the taxable range.
Is Any of It Actually Taxable?
Taxability turns on a figure the IRS calls provisional income: your child’s other income, plus any tax-exempt interest, plus half of the Social Security benefits from Box 5 of the SSA-1099. Compare that total to the thresholds in 26 U.S.C. § 86:2Office of the Law Revision Counsel. 26 USC 86 – Social Security and Tier 1 Railroad Retirement Benefits
- Below $25,000: none of the benefits are taxable. This is where the vast majority of children land.
- Between $25,000 and $34,000: up to 50% of the benefits may be included in taxable income.
- Above $34,000: up to 85% of the benefits may be taxable.
These are the single-filer thresholds, which is how a dependent child files. They are set by statute and have not been adjusted since 1994, so they still apply for the 2025 tax year. A child whose only income is a $12,000 annual benefit has provisional income of $6,000. Zero of the benefits are taxable.
To hit $25,000 in provisional income, a child would need significant wages, investment income, or trust distributions on top of the Social Security. That is uncommon for a minor, but it does happen, so run the number if your child has other income coming in.
Does Your Child Even Need to File?
Even when nothing is taxable, filing may still be required depending on total income. For 2025, a dependent child under 65 must file if any of these apply:3Internal Revenue Service. Publication 501, Dependents, Standard Deduction, and Filing Information
- Unearned income exceeded $1,350. Only the taxable portion of Social Security counts here. If none of the benefits are taxable, they do not push a child toward this threshold.
- Earned income exceeded $15,750 (wages, tips, self-employment).
- Gross income exceeded the larger of $1,350, or earned income (up to $15,300) plus $450.
Put these two rules together and the picture for most families is straightforward. If Social Security is your child’s only income and provisional income is under $25,000, the taxable amount is zero, unearned income for the filing test is zero, and no return is required. A summer job paying $800 does not change that; it is well below the earned-income floor.4Internal Revenue Service. Check If You Need to File a Tax Return
The picture shifts when a child holds investments, has a custodial account throwing off dividends, receives trust distributions, or works a substantial job. Then you run the provisional income calculation, see whether any of the benefits become taxable, and check the filing thresholds.
How to Report It When Filing Is Required
Start with your child’s Form SSA-1099. Box 5 shows net benefits for the year, meaning total benefits minus any repayments.5Social Security Administration. Social Security Administration POMS GN 05002.014 – Social Security Statement Box 5, Net Benefits
On your child’s Form 1040:
- Enter the Box 5 amount on Line 6a.
- Complete the Social Security Benefits Worksheet in the Form 1040 instructions (or the fuller version in Publication 915) to figure out the taxable portion.
- Enter the taxable amount on Line 6b.
The worksheet is just the provisional income math in step-by-step form: other income, plus tax-exempt interest, plus half of Box 5, compared against $25,000 and $34,000. Publication 915 has worked examples if you want to sanity-check the result.6Internal Revenue Service. 1040 (2025) Instructions1Internal Revenue Service. Publication 915 (2025), Social Security and Equivalent Railroad Retirement Benefits
File the return under your child’s Social Security number, not yours. Your own 1040 stays untouched by these benefits.
When the Kiddie Tax Applies
If your child has enough unearned income to file, the kiddie tax can also come into play. For 2025 and 2026, the first $1,350 of a child’s unearned income is covered by the standard deduction, the next $1,350 is taxed at the child’s own rate, and anything above $2,700 is taxed at the parent’s marginal rate. Crossing the $2,700 line means attaching Form 8615 to the child’s return.7Internal Revenue Service. Instructions for Form 8615 (2025)
Form 8615 applies when all of the following are true: the child had more than $2,700 in unearned income, is required to file a return, had at least one living parent at year-end, and did not file a joint return. Age-wise, it covers children under 18, 18-year-olds who did not earn more than half their own support, and full-time students aged 19 through 23 who also did not earn more than half their support.8Office of the Law Revision Counsel. 26 USC 1 – Tax Imposed
Taxable Social Security counts as unearned income for this test. A child with $3,500 in taxable benefits and $1,000 in dividends has $4,500 of unearned income, so the amount above $2,700 gets taxed at the parent’s rate. Rare in Social-Security-only households; more common when a custodial account or trust is in the mix.
Why Form 8814 Will Not Work Here
Form 8814 lets a parent report certain kinds of a child’s income on the parent’s own return, but the form is limited to interest, ordinary dividends, and capital gain distributions. Social Security benefits are not on that list.9Internal Revenue Service. Form 8814 – Parents Election To Report Childs Interest and Dividends
If your child has both Social Security and dividends, you still cannot fold the Social Security piece onto your return through Form 8814. The SSA-1099 is tied to your child’s Social Security number, and putting the amount on your return would generate an IRS mismatch notice.
Signing a Return for a Minor
A child too young to sign signs through a parent or guardian. The format the IRS uses: write the child’s name in the signature line, then “By,” then your signature, then your relationship, such as “parent” or “guardian.”10Internal Revenue Service. VITA/TCE Volunteer Resource Guide – Return Signature
E-file software walks through this by asking for the child’s information and then having the responsible adult sign. The child is the primary taxpayer on the return.
A Note on State Taxes
Most states either do not tax income at all or fully exempt Social Security. As of 2026, eight states tax Social Security to some degree: Colorado, Connecticut, Minnesota, Montana, New Mexico, Rhode Island, Utah, and Vermont. Each has its own exemptions, thresholds, and age-based rules, and a child’s benefits may still be fully exempt in those states. If you live in one, check the state’s department of revenue for how the rules apply at your child’s income level.
