What happens to your child's SSDI when they turn 18

When your child turns 18, their SSDI does not stop automatically. However, Social Security treats them as an adult from that point forward, which changes how the agency verifies their disability and how much they can earn without affecting their benefit. The payment itself continues if they remain disabled under the adult definition — but that definition is stricter than the childhood standard, and Social Security will conduct a Continuing Disability Review (CDR) around the time of the 18th birthday to confirm they still may have access to.

The most important shift is that your child's own income and resources now count toward their benefit, rather than your household income. This matters most if they work or receive other benefits. Additionally, if your child was receiving benefits partly because of your disability or retirement, that arrangement ends when they turn 18 — they must may have access to on their own record going forward.

You will receive a notice from Social Security before or shortly after the birthday explaining what happens next. If the agency determines your child no longer meets the adult disability standard, benefits will stop, usually with a notice giving you time to request reconsideration or appeal.

Key Takeaways

  • SSDI continues past age 18 only if your child meets the adult disability standard, which requires more severe impairment than the childhood standard.
  • Social Security will review your child's case around age 18 and may stop benefits if the disability no longer meets adult criteria.
  • Once your child turns 18, their own earnings and resources affect the benefit amount, and your household income no longer matters.
  • If your child works, they can use work incentives like the Student Earned Income Exclusion (if still in school) or Impairment Related Work Expenses to protect part of their earnings.
  • Your child can request reconsideration or file an appeal if Social Security denies continued benefits at the age-18 review.

The adult disability standard and the age-18 review

Social Security uses a different definition of disability for adults than for children. A child's disability is measured partly by how much help they need and how much their condition limits their ability to function in daily life. An adult's disability is measured primarily by whether the condition prevents them from doing any substantial work — meaning work that earns more than a set monthly amount (currently $1,550 per month in 2024, though this figure changes yearly).

Because the adult standard is narrower, some children whose benefits were based on the childhood definition will not meet the adult standard when they turn 18. Social Security calls this the age-18 redetermination. The agency will send you a notice asking for updated medical records and information about your child's current functioning. You have the right to submit your own statement about your child's abilities and limitations.

If Social Security concludes your child no longer qualifies, the notice will explain why and tell you how to request reconsideration or appeal. You typically have 60 days from the date of the notice to request reconsideration, and you can ask for a hearing before an administrative law judge if you disagree with the reconsideration decision.

How your child's work and earnings affect their benefit

Once your child turns 18, Social Security counts their own wages against their SSDI benefit. For every dollar earned above a monthly threshold (currently $1,550 in 2024), the benefit is reduced by 50 cents. This is called the Substantial Gainful Activity (SGA) limit. If your child earns more than the SGA amount, Social Security may determine they are no longer disabled and stop benefits entirely.

However, several work incentives allow your child to earn money while keeping some or all of their benefit. The Student Earned Income Exclusion (SEIE) lets students under age 22 exclude up to $2,170 per month in wages (2024 figure) when calculating whether they have exceeded SGA — meaning they can earn that much without it counting against their benefit. The Plan to Achieve Self-Support (PASS) lets your child set aside income and resources for a specific work goal, such as training or education, without those amounts affecting their benefit. Impairment Related Work Expenses (IRWE) allow deductions for costs directly related to working — such as attendant care, medications, or transportation — that would not be necessary if your child were not working.

Your child should report all work and earnings to Social Security promptly. Failing to report can result in overpayments that must be repaid. Social Security has a Work Incentives Planning and information (WIPA) project in most states that offers free counseling on how work affects benefits; your local Social Security office can provide the contact information.

Medicare and Medicaid after age 18

Your child's Medicare coverage continues without change when they turn 18. They remain may have access to to Medicare Part A (hospital insurance) and Part B (medical insurance) as long as they receive SSDI, regardless of age. There is no separate process or renewal needed solely because of the birthday.

Medicaid is more complex because it is run by each state. In most states, your child's Medicaid continues automatically if they remain on SSDI. However, some states have different rules for adults, and a few states use income limits that might affect your child once they turn 18 and their own income is counted. Contact your state Medicaid agency or your local Social Security office to confirm your child's Medicaid status after the birthday.

If your child's SSDI stops because they no longer meet the adult disability standard, their Medicare and Medicaid may also stop. However, federal law allows a period of continued Medicaid coverage (usually up to 93 days) after SSDI ends due to work or earnings. Your child may also be able to purchase Medicare Part A and Part B if they lose coverage; Social Security can explain the options.

What you need to do before and after the 18th birthday

Before your child's 18th birthday, gather recent medical records and documentation of their current condition and functioning. Social Security will request these as part of the age-18 review, and having them ready speeds the process. If your child has been receiving special education or vocational rehabilitation services, ask the school or agency for a summary of their abilities and limitations.

After the birthday, watch for a notice from Social Security about the age-18 review. If you do not receive one within a few weeks, contact your local Social Security office to confirm the review is underway. Once you receive the notice, respond promptly with the requested information. If Social Security denies continued benefits, you have the right to request reconsideration and, if necessary, to appeal to an administrative law judge.

If your child is working or planning to work, report the job and earnings to Social Security right away. Ask about work incentives that might protect part of the earnings. If your child is still in school, the Student Earned Income Exclusion may allow them to work part-time without affecting their benefit.

Continuing benefits if your child has severe impairment

If your child has a condition that is clearly severe and permanent — such as total blindness, deafness, or a severe intellectual disability — Social Security may conduct a less intensive review at age 18. The agency calls this a medical improvement review standard (MIRS). Rather than asking whether your child currently meets the disability standard, the agency asks whether there has been medical improvement since the last review. If there has been no improvement, benefits typically continue without interruption.

Even with a MIRS, Social Security will still update your child's file and may request recent medical records. The process is usually faster and less uncertain than a full age-18 redetermination, but it is not automatic. You should still respond to any notice and provide current medical documentation.

Frequently Asked Questions

Can my child keep SSDI if they go to college?

Yes. SSDI is not affected by school attendance or enrollment status. However, if your child works while in college, the Student Earned Income Exclusion allows them to earn up to $2,170 per month (2024) without it counting against their benefit, as long as they are under age 22 and a full-time student. Report the job to Social Security so the exclusion is applied correctly.

What if Social Security says my child no longer qualifies at age 18?

You can request reconsideration within 60 days of the notice. If you disagree with the reconsideration decision, you can request a hearing before an administrative law judge. You have the right to submit new medical evidence and to have a representative (such as a lawyer or advocate) help you at the hearing. Many disability advocates and legal aid organizations offer free or low-cost representation.

Does my child's SSDI affect their SSI or other benefits?

SSDI and SSI are separate programs. Your child cannot receive both at the same time. If your child receives SSI (Supplemental Security Income) instead of SSDI, different rules explore at age 18. Contact Social Security to confirm which program your child is on and what changes to expect.

What happens if my child's condition improves?

If your child's condition improves significantly, Social Security may stop benefits. However, the agency must find that there has been medical improvement and that your child can now work. You have the right to appeal. Additionally, if benefits stop due to medical improvement, your child may be able to request expedited reinstatement if the condition worsens again within five years.

Can my child work and still receive the full SSDI benefit?

Not if earnings exceed the SGA limit ($1,550 in 2024). However, work incentives such as the Student Earned Income Exclusion, Impairment Related Work Expenses, and Plans to Achieve Self-Support can reduce or eliminate the impact of work on the benefit. A WIPA counselor can help your child figure out how much they can earn while keeping their benefit.
