SSDI ends or changes when your child turns 18, but the exact date depends on whether they are still in high school

If you receive SSDI as a parent caring for a disabled child, or if you are the disabled person receiving benefits, you need to know that the rules change on the month your child turns 18. The Social Security Administration does not automatically stop payments, but it does review the case and may reduce or end benefits depending on school status and work activity. A child still enrolled in high school full-time can continue receiving SSDI through the month they turn 19, or until they graduate, whichever comes first. A child who has already left school, dropped out, or graduated before turning 18 loses SSDI the month they turn 18.

This is not a surprise termination—Social Security sends a notice before the change happens—but many families miss the notice or do not understand what it means. The key is understanding which rule applies to your situation and what you need to report to Social Security to keep benefits flowing if your child is still in school.

Key Takeaways

  • A child in high school full-time can receive SSDI until the month they turn 19 or graduate, whichever is earlier; a child who has left school loses benefits the month they turn 18.
  • You must report school status to Social Security before your child's 18th birthday, or the agency will assume they are not in school and stop payments.
  • Social Security counts only attendance at a public or accredited private high school; homeschooling, GED programs, and college do not extend benefits past 18.
  • If your child works and earns over the monthly limit (which changes yearly), SSDI will be reduced or stopped regardless of school status.
  • You have the right to request a new decision if Social Security stops benefits and you believe the decision was wrong.

The high school exception: how to keep benefits past 18

The only way SSDI continues past age 18 is if your child is enrolled full-time in an accredited high school and you report this to Social Security. "Full-time" means your child is taking a normal course load and attending classes regularly. Social Security does not count part-time enrollment, online-only high school programs, or alternative schools unless they are accredited and lead to a high school diploma.

You do not need to wait for Social Security to ask. Contact your local Social Security office or call 1-800-772-1213 at least two months before your child's 18th birthday and tell them your child is still in high school. Provide the school name, the expected graduation date, and confirmation that your child is enrolled full-time. Social Security will ask you to sign a form (usually the SSA-454, "Report of Earnings and Work Activity") confirming school status. Keep a copy of this form and any written confirmation from the school.

If you do not report school status, Social Security will assume your child is not in school and will stop SSDI the month they turn 18. Even if your child is sitting in class, the payment will end. You can request a new decision after the fact, but it is much faster to report before the birthday.

When SSDI stops at 18 regardless of school status

SSDI ends the month your child turns 18 if any of these explore: your child has already graduated from high school, your child dropped out of school, your child is attending college or a trade school, your child is homeschooled, or your child is working and earning over the monthly work limit.

The work limit changes each year. In 2024, the limit is $1,550 per month in earned income (wages from a job). If your child earns more than this in any month, SSDI is reduced or stopped for that month and any month after. This applies even if your child is still in high school. Social Security counts only wages from work, not money from family, gifts, or other sources.

If your child is in a GED program, a vocational school, or any post-secondary program, SSDI ends at 18. Social Security does not extend benefits for any form of education after high school, even if your child is not yet 19.

What to expect in the months before and after the 18th birthday

Social Security sends a notice called a "Redetermination Notice" or "Age-18 Redetermination" about 60 days before your child's birthday. This notice explains the rules and asks you to report whether your child is in school. You must respond to this notice, even if you have already called Social Security. Respond by mail, phone, or in person at your local office.

If your child is in school and you report it correctly, SSDI continues without interruption. The payment amount may change because the rules for how much a disabled child receives are different from the rules for a disabled adult, but benefits do not stop. If your child is not in school or you do not report school status, the final payment arrives the month your child turns 18. After that, no payment is issued unless you request a new decision and win.

If your child's case is closed and you believe it was closed in error, you have 60 days from the date on the notice to request a new decision. This is called a "reconsideration." You do not have to pay for this; it is free. Contact Social Security and ask for a reconsideration form, or submit a written request that includes your child's Social Security number, the date the decision was made, and why you think it was wrong.

What happens to parent benefits when the child turns 18

If you are receiving SSDI as a parent because you are caring for your disabled child, your benefits do not automatically stop when your child turns 18. However, your case will be reviewed. If your child's benefits end because they are not in school or are working, your benefits may also end or be reduced, depending on your own disability status and work history.

If you are receiving benefits only because you are the parent of a disabled child (called "parent's insurance benefit"), those benefits will end when your child's SSDI ends. If you are receiving SSDI on your own record as a disabled worker, your benefits continue regardless of what happens to your child's case.

Contact Social Security to understand your own situation. Bring your Social Security number, your child's Social Security number, and any notices you have received. Social Security staff can explain whether your benefits will change.

Reporting changes after age 18

If your child turns 18 and SSDI ends, but then your child re-enrolls in high school or circumstances change, you can report the change to Social Security. However, benefits do not restart automatically. You must request a new decision, and Social Security will review whether your child meets the rules for the extension.

If your child was working and earning over the limit, and then stops working or reduces hours below the limit, report this change when ready. SSDI may restart the following month. Keep records of your child's pay stubs, employer letters, or other proof of earnings or job loss.

Any change in school status, work status, living situation, or income should be reported to Social Security within 10 days. You can report by phone at 1-800-772-1213, by mail to your local office, or in person. Always ask for written confirmation of what you reported.

What to do if you receive a notice that SSDI is ending

Read the notice carefully and look for the reason SSDI is ending. Common reasons are: "beneficiary reached age 18 and is not in school," "beneficiary is working and earnings exceed the limit," or "beneficiary graduated from high school." The notice will include a date the payment stops and instructions for requesting a new decision.

If you disagree with the reason, you have 60 days from the date on the notice to request reconsideration. You do not need a lawyer to do this. Write a letter to your local Social Security office that includes your child's name, Social Security number, the date of the notice, and a clear explanation of why you think the decision is wrong. For example: "My child is still enrolled full-time at Lincoln High School and will graduate in June 2025" or "My child stopped working on [date] and has not earned income since then."

Include any proof you have: a school enrollment letter, a termination letter from the employer, recent pay stubs showing zero earnings, or a graduation diploma. Mail this letter to your local Social Security office or bring it in person. Ask for a receipt showing the date you submitted it.

Frequently Asked Questions

Can my child stay on SSDI if they go to college?

No. SSDI ends at 18 for anyone not in high school, including those attending college, trade school, or any post-secondary program. If your child plans to attend college, you may want to explore other programs, such as Supplemental Security Income (SSI) if your child has limited income and resources, or Medicaid, which may continue under different rules.

What if my child is homeschooled?

Homeschooling does not extend SSDI past 18. Social Security only recognizes enrollment in an accredited public or private high school. If your child is homeschooled, SSDI ends the month they turn 18, even if they are working toward a high school diploma.

Does my child have to tell Social Security about a part-time job?

Yes. Any earned income must be reported to Social Security within 10 days. If your child earns over the monthly limit (currently $1,550 in 2024), SSDI will be reduced or stopped. Even if your child is in school, work earnings can end benefits.

What if Social Security made a mistake and stopped SSDI too early?

You can request reconsideration within 60 days of the notice. Submit a written request with proof that your child was still in high school or that the reason for stopping was incorrect. If you miss the 60-day window, you can still appeal, but the process takes longer and you may not receive back pay.

Does my child's SSDI automatically restart if they drop out of college and re-enroll in high school?

No. You must request a new decision and provide proof of re-enrollment. Social Security will not restart benefits without a new process and review. Contact your local office as soon as your child re-enrolls to start the process.
