Child SSDI is taxable only if your child has other income or you file jointly

Your child's SSDI payment by itself does not trigger a tax bill. However, if your child has earned income (from a job) or unearned income (interest, dividends, or other SSDI), the combination of that income plus the SSDI may be taxable. The threshold depends on your child's age and filing status, and whether you claim your child as a dependent on your own return.

The IRS treats SSDI differently from other income. A portion of the benefit becomes taxable only when your child's "combined income" exceeds a certain amount. Combined income is calculated as adjusted gross income plus nontaxable interest plus half of the SSDI benefit. This formula is the same whether your child is 8 or 28.

If your child has no other income and you claim them as a dependent, their SSDI alone will not be taxed. But if your child works part-time, receives a pension, or has investment income, you will need to run the calculation or file a return to know for certain.

Key Takeaways

  • Child SSDI is not taxable unless your child has other income that pushes combined income above the IRS threshold.
  • Combined income includes half of the SSDI benefit plus all other income your child receives, including wages from work.
  • If your child is claimed as a dependent and has no earned or unearned income, you do not file a tax return for them.
  • If your child works or has other income, you may need to file a return even if no tax is owed, because the IRS uses the return to determine how much SSDI is taxable.
  • The taxable portion of SSDI can be 0%, 50%, or up to 85% of the benefit, depending on how much other income your child has.

How the IRS calculates taxable SSDI for a dependent child

The IRS uses a two-tier system. If your child's combined income is below a certain threshold, none of the SSDI is taxable. If combined income exceeds that threshold, up to 50% of the SSDI becomes taxable. If combined income is very high, up to 85% becomes taxable.

For a dependent child in 2024, the first threshold is $25,000 of combined income. If your child's combined income is $25,000 or less, no SSDI is taxable. If combined income is between $25,000 and $34,000, up to 50% of the SSDI is taxable. If combined income exceeds $34,000, up to 85% is taxable.

Combined income is not the same as total income. It is calculated as: adjusted gross income (wages, self-employment income, taxable interest, taxable dividends, capital gains, and other taxable income) plus nontaxable interest (such as interest from municipal bonds) plus half of the SSDI benefit received during the year.

Example: Your 16-year-old receives $12,000 in SSDI for the year and earns $8,000 from a summer job. Combined income is $8,000 (wages) + $0 (no other income) + $6,000 (half of $12,000 SSDI) = $14,000. Since $14,000 is below $25,000, none of the SSDI is taxable. Your child owes no federal income tax on the SSDI, though you may still need to file a return because of the $8,000 in wages.

When you must file a tax return for your child

You are required to file a federal income tax return for your dependent child if their earned income (wages) exceeds a certain amount, or if their unearned income (interest, dividends, SSDI, pensions) exceeds a certain amount. For 2024, the threshold for earned income is $14,600. The threshold for unearned income is $1,300.

If your child receives only SSDI and has no other income, you do not file a return. If your child works and earns $5,000, you must file a return even though no SSDI is taxable, because the earned income alone exceeds the filing threshold. If your child receives $2,000 in interest and $12,000 in SSDI, you must file because the unearned income exceeds $1,300.

Filing a return does not mean your child owes tax. It means you submit a form to the IRS so they can verify that no tax is owed and that your child is not may have access to to a refund (such as the Earned Income Tax Credit). Some families file even when no return is required, because a return can result in a refund of taxes withheld from wages.

SSDI and the Earned Income Tax Credit for your child

If your child works and earns wages, they may be may have access to to the Earned Income Tax Credit (EITC), even if they also receive SSDI. The EITC is a refundable credit, meaning the IRS can send your child money even if no tax is owed. The credit is based on earned income only; SSDI does not count toward the credit.

To claim the EITC, you must file a tax return. The credit amount depends on your child's filing status and how much they earned. For a single filer with no children in 2024, the maximum credit is $600 if earned income is between roughly $11,000 and $17,000. The exact amount changes each year.

If your child is claimed as a dependent on your return, they cannot also claim themselves on their own return. However, they can still file their own return to report wages and claim the EITC. The credit goes to your child, not to you, even though you claim them as a dependent on your return.

Reporting your child's SSDI on your own tax return

You do not report your child's SSDI on your own tax return. SSDI is not income to you; it belongs to your child. However, if you claim your child as a dependent, you may be able to claim a dependent exemption or credit, depending on the year and your income level. The rules for dependent credits change frequently, so check the IRS website or a tax preparer for the current year.

If you receive benefits as a parent caring for a child with a disability, those benefits are reported on your own return under your own Social Security number. Your child's SSDI is separate and reported only on your child's return (if a return is required).

Some parents worry that claiming a child as a dependent will affect the child's SSDI. It does not. The Social Security Administration does not reduce SSDI based on whether the child is claimed as a dependent for tax purposes. These are two separate systems.

State income tax on child SSDI

Most states do not tax SSDI, whether it is your own benefit or your child's. However, a few states tax SSDI under certain conditions. Vermont, Colorado, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, and Utah tax SSDI in some situations, usually when income is above a state-specific threshold.

If you live in one of these states, you may owe state income tax on your child's SSDI even if no federal tax is owed. State rules vary widely. Some states exempt SSDI entirely for residents over a certain age or with income below a threshold. Others tax SSDI the same way the federal government does.

Contact your state's department of revenue or a tax preparer familiar with your state's rules. The Social Security Administration's website lists state tax treatment of SSDI, but the rules change and you should verify the current rule for your state before filing.

What to do if your child's SSDI was already taxed

If your child's employer withheld federal income tax from wages, or if your child made estimated tax payments, they may be may have access to to a refund even if no tax was owed. This happens when the combination of SSDI and wages results in no taxable income, but tax was already paid.

File a federal income tax return for your child using Form 1040 or 1040-SR (if your child is 65 or older). Report all income, including wages and SSDI. The IRS will calculate whether any tax is owed and whether a refund is due. If a refund is owed, it will be sent to your child's address or deposited into their bank account if they provided direct deposit information.

You can file the return yourself using free tax software (the IRS Free File program is available to households under a certain income threshold), or you can hire a tax preparer. If your child's situation is straightforward — only wages and SSDI, no other income — free software is usually sufficient.

Frequently Asked Questions

Does my child's SSDI count as income when I claim them as a dependent?

No. Your child's SSDI does not affect your ability to claim them as a dependent. The IRS does not count SSDI as income to you. You can claim your child as a dependent as long as they meet the other requirements: they are your child (or a may have access to relative), they live with you for the entire year, and you provide more than half their financial support.

If my child works part-time, do I have to file a tax return for them?

Yes, if their earned income exceeds $14,600 in 2024. You must file a return even if no tax is owed, so the IRS can verify their income and process any refund they are may have access to to. If your child earned less than $14,600 and has no other income, you do not have to file.

Can my child claim themselves as a dependent if I already claim them?

No. Only one person can claim your child as a dependent. If you claim them on your return, your child cannot claim themselves, even if they file their own return to report wages or claim the Earned Income Tax Credit.

What if my child receives SSDI and also gets a pension or inheritance?

Pensions and inheritances are unearned income. They count toward the combined income threshold. If your child's combined income (pension or inheritance plus half of SSDI) exceeds $25,000, a portion of the SSDI becomes taxable. You will need to file a return and calculate the taxable amount, or use tax software or a preparer to do so.

Will filing a tax return affect my child's SSDI benefits?

No. Filing a tax return does not change your child's SSDI benefit amount. The Social Security Administration does not use tax returns to calculate benefits. However, if your child's income changes (such as starting a job), you must report that to Social Security, because earned income can affect SSDI under the Substantial Gainful Activity rules.
