You do not claim your child’s survivor benefits on your own tax return. Social Security survivor payments made to a child belong to the child for tax purposes, even when you are the representative payee who receives and manages the money. And for most families, there is nothing to report anywhere: a child whose only income is the survivor benefit almost never owes federal tax on it.
The Child’s Benefits Belong on the Child’s Return, Not Yours
This is the point that trips up most parents. You may cash the checks, deposit them, and spend them on the child’s housing, food, and school costs. You may claim the child as a dependent. None of that changes who the benefits belong to for tax purposes. The IRS states plainly that “the taxability of benefits must be determined using the income of the person entitled to receive the benefits.”1Internal Revenue Service. Social Security Income
So your income is not part of the calculation. The SSA-1099 that arrives in the child’s name in January is the child’s tax document, not yours. Do not add its numbers to your Form 1040. If a return needs to be filed for the child, you sign it on their behalf as parent or guardian.
Why Most Children Owe No Tax on These Benefits
Social Security benefits only become taxable once the recipient’s “combined income” crosses $25,000 for a single filer. Combined income is your other income for the year, plus any tax-exempt interest, plus half of your Social Security benefits.2Office of the Law Revision Counsel. 26 USC 86 – Social Security and Tier 1 Railroad Retirement Benefits A child with no job and no investment income has no other income to add. Half of the benefits is the whole calculation.
Consider a child receiving $1,500 a month, or $18,000 for the year. Half of that is $9,000. With no other income, combined income is $9,000, well under the $25,000 threshold. None of the benefits are taxable, and no return is required for the benefits alone. The IRS confirms this outcome as the norm, noting that “a child generally won’t receive enough additional income to make the child’s Social Security benefits taxable.”1Internal Revenue Service.

When a Portion Could Actually Be Taxable
The picture changes only if the child has meaningful income of their own. A teenager working a well-paying part-time job, a beneficiary of a trust throwing off dividends, or a child with substantial savings interest could see combined income climb toward the threshold. Once combined income passes $25,000, up to 50% of the benefits can be included in taxable income. Above $34,000, up to 85% can be. Even at the top, no more than 85% of the benefits is ever taxable; the remaining 15% stays tax-free.2Office of the Law Revision Counsel. 26 USC 86 – Social Security and Tier 1 Railroad Retirement Benefits
A child may also be required to file for reasons unrelated to Social Security, such as wages above the filing threshold or unearned income above $1,350. If a return has to be filed anyway, the SSA-1099 comes with it.
Where the Kiddie Tax Fits In
The Kiddie Tax is a separate rule aimed at investment income shifted from parents to children. It applies when a child’s unearned income (interest, dividends, capital gains) exceeds $2,700 for 2026, taxing the excess at the parent’s rate on Form 8615.3Internal Revenue Service. Instructions for Form 8615 For a child whose only income is survivor benefits, it has no effect, because those benefits are not taxable in the first place. It matters only when a child has both taxable Social Security benefits and significant investment income.4Internal Revenue Service. Topic No. 553 – Tax on a Childs Investment and Other Unearned Income (Kiddie Tax)
Filing a Return for the Child When One Is Needed
Each January, the Social Security Administration mails Form SSA-1099 to every beneficiary, including children. The 2025 form also becomes available online starting February 1, 2026.5Social Security Administration. Get Tax Form (1099/1042S) Box 5 shows net benefits for the year, the number used in the tax calculation.6Social Security Administration. Social Security Statement – Box 5, Net Benefits
If a return needs to be filed in the child’s name, the Box 5 total goes on Line 6a of the child’s Form 1040. The taxable portion, if any, goes on Line 6b.7Internal Revenue Service. 2025 Instructions for Form 1040 The Social Security Benefits Worksheet in the Form 1040 instructions or in Publication 915 walks through the combined income math and produces the exact figure for Line 6b. If the worksheet result is zero, enter $0.8Internal Revenue Service. Publication 915 – Social Security and Equivalent Railroad Retirement Benefits
Keep the SSA-1099 with the child’s tax records whether or not a return is filed. It is proof of what was paid and to whom.
Lump-Sum Back Payments
Survivor claims often produce a retroactive lump sum covering several months, sometimes stretching into a prior year. The taxable portion is included in the year the payment is received, not the year it was owed. Amending old returns to spread it back is not allowed.9Internal Revenue Service. Back Payments
An alternative calculation can soften the hit. If part of the lump sum covers a prior year, the child can figure the taxable amount as if that portion had been received in the earlier year, using that year’s income. If the result is lower, that method is used instead. To make the election, check the box on Line 6c of Form 1040 and complete the lump-sum worksheets in Publication 915.9Internal Revenue Service. Back Payments It is worth running the numbers whenever a retroactive award pushes combined income into a higher tier.
State Tax
Most states do not tax Social Security benefits. As of 2026, eight states impose some level of state income tax on Social Security income: Colorado, Connecticut, Minnesota, Montana, New Mexico, Rhode Island, Utah, and Vermont. Each has its own exemptions and thresholds, so benefits that are partially taxable federally may still be exempt at the state level. If you live in one of these states, check with the state tax agency for the current rules. Everywhere else, state tax on a child’s survivor benefits is not a concern.
