Who Must File Taxes on a Child's SSDI Income

A child who receives SSDI benefits does not automatically have to file a tax return just because they get those payments. Whether your child must file depends on their total income for the year — not SSDI alone, but SSDI plus any other income they earned, such as wages from a job or interest from a bank account.

The threshold changes each year. For 2024, a child with no income other than SSDI does not have to file. However, if your child has earned income (money from work) of $1,150 or more, or unearned income (interest, dividends, or other non-work money) of $500 or more, they must file a return. If your child has both types of income, the rule is more complex — the IRS uses a combined calculation.

SSDI itself is not taxable income in most cases. This means you count it toward the income threshold that determines whether a return is required, but it does not create a tax bill on its own. The tax obligation comes from other income your child earned or received.

Key Takeaways

  • SSDI payments are not taxable, but your child must file a return if they have earned income of $1,150 or more, or unearned income of $500 or more in the same year.
  • You claim your child as a dependent on your own return if they live with you and you pay more than half their support, which affects the standard deduction they can claim.
  • The IRS Form 1040 or 1040-SR is the main return form; your child may also need Schedule 1 if they have self-employment income or certain other sources.
  • Filing by April 15 is required even if your child does not owe taxes, because they may be due a refund of withheld income.
  • The Social Security Administration does not report SSDI to the IRS as income, so you must report any other income your child received on their own return.

How Dependent Status Affects Your Child's Tax Filing

If your child lives with you and you pay more than half their living expenses for the year, you claim them as a dependent on your own tax return. This is true even though they receive SSDI. Being claimed as a dependent changes the standard deduction your child can claim on their own return.

When your child is your dependent, their standard deduction for 2024 is limited to the greater of $1,150 or their earned income plus $450 — not the full standard deduction that an independent person would get. This means if your child earned $2,000 from a job, their standard deduction would be $2,450 ($2,000 plus $450), not the full amount. This lower deduction means more of their income is subject to tax.

You must decide each year whether claiming your child as a dependent benefits your household overall. Claiming them reduces your taxable income and may lower your tax bill or increase your refund. However, it also raises the amount of your child's income that is taxable. A tax professional can help you compare the two scenarios.

What Forms and Documents You Need

Your child will file Form 1040 or Form 1040-SR (the standard individual income tax return). Most children use Form 1040. Form 1040-SR is for people age 65 or older and has slightly larger print, but the rules are the same.

If your child has self-employment income — money from work they did as their own boss, not as an employee — they also file Schedule C (Profit or Loss from Business) or Schedule C-EZ (simplified version). If they have income from sources other than wages or self-employment, such as interest or dividends, they file Schedule 1 (Additional Income and Adjustments to Income).

Gather these documents before you file:

  • Form W-2 from each employer (if your child worked as an employee)
  • Form 1099-INT for interest income from banks or savings accounts
  • Form 1099-DIV for dividend income from investments
  • Form 1099-MISC or 1099-NEC for other income, such as freelance work or prizes
  • Records of any federal income tax withheld from paychecks or other payments
  • Your Social Security number and your child's Social Security number

The Social Security Administration does not send a form reporting SSDI to the IRS. You do not report SSDI as income on the return.

Filing Your Child's Return Step by Step

You can file your child's return using tax software, by mail, or with the help of a tax professional. The IRS Free File program offers free software to households under a certain income threshold — check IRS.gov to see if your family qualifies.

If you use tax software: Enter your child's name, Social Security number, and date of birth. Select "dependent" when asked about filing status. Enter all income from W-2s and 1099 forms. The software will calculate whether your child owes tax or is due a refund. Review the return for accuracy before submitting it electronically.

If you file by mail: Complete Form 1040 by hand, attach copies of all W-2s and 1099s, and mail the package to the IRS address listed in the Form 1040 instructions (the address depends on your state). Keep a copy for your records. Mail by April 15 or request an extension using Form 4868 if you need more time.

If you use a tax professional: Bring all W-2s, 1099s, and records of withheld tax to their office. They will prepare the return and file it on your behalf. You will receive a copy to sign and keep.

important date and What Happens If You Miss Them

The important date to file a 2024 tax return is April 15, 2025. If your child owes tax and you do not file by this date, the IRS charges penalties and interest on the unpaid amount. If your child is due a refund, there is no penalty for filing late, but you lose the refund if you do not file within three years of the important date.

If you cannot file by April 15, you can request a six-month extension by filing Form 4868 (process for Automatic Extension of Time To File U.S. Individual Income Tax Return) before the important date. An extension gives you until October 15 to file, but it does not extend the important date to pay any tax owed. If your child owes tax, you must estimate the amount and pay it by April 15 to avoid penalties.

The IRS accepts returns filed electronically year-round. Paper returns filed after April 15 may take longer to process. If your child is due a refund, filing early — even in January or February — means the refund arrives sooner.

SSDI and Supplemental Security Income (SSI) Are Taxed Differently

SSDI (Social Security Disability Insurance) is not taxable. However, if your child receives Supplemental Security Income (SSI) instead of or in addition to SSDI, the rules are different. SSI is also not taxable as income, but it counts toward the income limits that determine whether your child must file a return.

Some children receive both SSDI and SSI. SSDI is based on a parent's or guardian's work record; SSI is a needs-based program for people with low income and resources. Neither is taxable, but both count when you calculate whether your child's total income triggers a filing requirement.

If you are unsure whether your child receives SSDI, SSI, or both, check the benefit statement the Social Security Administration sends each year. It will say "SSDI" or "SSI" on the document. You can also call Social Security at 1-800-772-1213 to confirm.

When Your Child Owes Tax or Gets a Refund

After you file your child's return, the IRS will either send a refund or a bill. A refund happens when your child had income tax withheld from paychecks or other payments but does not owe that much tax (or owes none). A bill happens when your child's income is high enough to owe tax but no tax was withheld.

If your child worked as an employee, their employer withheld federal income tax from each paycheck. The amount withheld depends on the W-4 form your child filled out when hired. If too much was withheld, your child gets a refund. If too little was withheld, your child owes tax.

If your child had self-employment income and did not pay estimated tax during the year, they may owe tax when they file. Self-employed people are expected to pay tax four times a year (quarterly estimated tax). If your child earned self-employment income, a tax professional can help you understand whether estimated payments are required next year.

Frequently Asked Questions

Does my child have to file if they only received SSDI and no other income?

No. SSDI alone does not require a tax return. Your child must file only if they have earned income of $1,150 or more, or unearned income of $500 or more in the same year. If SSDI is their only income, they do not have to file.

Can I claim my child as a dependent if they receive SSDI?

Yes, if your child lives with you and you pay more than half their living expenses. SSDI does not change the dependent rules. Claiming them as a dependent lowers your taxable income but also lowers the standard deduction your child can claim on their own return.

What if my child earned money from a part-time job and also receives SSDI?

You report only the job income on your child's tax return. SSDI is not reported as income. If the job income is $1,150 or more, your child must file. The SSDI does not count toward the $1,150 threshold, but it may affect other benefits — check with Social Security about work incentives before your child starts working.

Where do I report SSDI on the tax return?

You do not report SSDI anywhere on the return. SSDI is not taxable income. Report only other income your child received, such as wages, interest, or self-employment earnings.

What if I did not receive a W-2 or 1099 for my child's income?

Contact the person or business that paid your child and ask for the form. If they do not send it by January 31, you can file the return without it and report the income based on your own records. However, the IRS may contact you later if the amount does not match what the payer reported. It is better to get the form or written confirmation of the amount before filing.
