Your SSDI payment stops when your child turns 18 in most cases

When your child reaches 18, the child's benefit — the money paid to them as your dependent — ends. Your own SSDI payment does not increase to replace it. The total household benefit goes down by whatever amount your child was receiving each month.

There is one exception: if your child is still in high school full-time, benefits can continue until they graduate or turn 19, whichever comes first. After that point, the benefit stops regardless of whether they have graduated.

If your child becomes disabled before age 22, they may be able to receive disabled adult child (DAC) benefits on your record instead. This is a separate program with its own rules and does not affect your own payment amount.

Key Takeaways

  • Your SSDI payment amount does not change when your child turns 18; only your child's benefit ends.
  • If your child is still in high school full-time, their benefit continues until graduation or age 19, whichever is earlier.
  • A child who becomes disabled before age 22 may may have access to for disabled adult child benefits, which is a separate benefit with its own payment amount.
  • You must notify Social Security within 10 days of your child's 18th birthday or high school graduation to avoid overpayment.

How the payment change works

Your SSDI benefit is calculated based on your own work record and disability. When you have a child under 18 receiving benefits on your record, Social Security pays you as the beneficiary and also pays your child a separate amount — typically 50 percent of your primary insurance amount (PIA), though the exact percentage depends on how many family members are receiving benefits.

When your child turns 18 and is no longer may be able to access, that child's payment stops. Your own payment continues unchanged. The household loses the child's portion of the benefit, which usually means a significant drop in total family income.

This is different from how some other benefit programs work. You do not receive a "makeup" payment or an increase to your own benefit to offset the loss of your child's benefit.

The high school exception and how to report it

Social Security allows benefits to continue for a child who is still enrolled full-time in high school after they turn 18. The benefit stops on the earlier of two dates: the month they graduate or the month they turn 19.

You must report your child's graduation to Social Security within 10 days. Call your local Social Security office, go in person, or report it online through your my Social Security account. If you do not report the graduation, Social Security will continue paying the benefit, and you will owe back the overpayment once they discover the error — even if the overpayment was not your fault.

If your child drops out of high school before turning 19, the benefit ends the month after they stop attending. You should report this change as well, though the rules are stricter: Social Security may ask for proof that your child is no longer enrolled.

Disabled adult child benefits as an alternative

If your child becomes disabled before age 22, they may may have access to for disabled adult child (DAC) benefits on your SSDI record. This is not automatic — you must report the disability to Social Security and they will make a separate information about whether your child meets the disability standard for adults.

DAC benefits are paid at the same rate as the child benefit was (typically 50 percent of your PIA), but they continue for life as long as your child remains disabled. The benefit does not depend on your child's age or school status once they turn 18.

To start the DAC process, contact Social Security and ask them to develop a claim for disabled adult child benefits. You will need medical evidence of the disability, including treatment records and a current diagnosis. The review process typically takes several months.

What to do before your child turns 18

Start planning for the income loss at least two months before your child's 18th birthday. Review your household budget and identify what expenses will change. Some families use the remaining time to help their child prepare for work or post-secondary training.

If your child has a disability that may may have access to for DAC benefits, gather medical records now rather than waiting until after the child benefit ends. Having documentation ready speeds up the DAC information process.

If your child is in high school and will turn 18 before graduation, make sure Social Security has the correct expected graduation date on file. You can verify this by logging into your my Social Security account or calling your local office.

Reporting changes to Social Security

You are responsible for telling Social Security when your child's circumstances change. The main changes that affect benefits are graduation, dropping out of school, turning 19, or becoming disabled.

You can report changes in three ways: by phone at 1-800-772-1213, in person at your local Social Security office, or online through your my Social Security account if you have set one up. When you report, have your child's Social Security number and the date of the change ready.

Keep a record of when you reported the change and who you spoke with. If Social Security later says you did not report it, you will have documentation to show you did.

Frequently Asked Questions

Can my child keep the benefit if they go to college?

No. Once your child turns 18 and is no longer in high school, the benefit ends regardless of whether they are in college, trade school, or any other type of education. Only full-time high school enrollment extends the benefit past 18.

What if my child turns 18 mid-month?

Social Security pays benefits for the entire month in which your child turns 18. The benefit ends the following month. For example, if your child turns 18 on June 15, you receive the full June payment, and the benefit stops in July.

Do I have to pay back the overpayment if I forget to report graduation?

Yes. If Social Security continues paying your child's benefit after graduation because you did not report it, you will owe back the overpayment. Social Security may recover it by reducing future payments or asking you to repay it directly. Report graduation within 10 days to avoid this.

Can my child work and still get the benefit after 18?

Only if they are still in high school full-time. Work does not affect the benefit as long as they are enrolled. Once they graduate or turn 19, the benefit ends regardless of work status.

What happens if my child becomes disabled after they turn 18?

If the disability began before age 22, your child can still file for disabled adult child benefits. The disability does not have to be the same one they had as a minor. Contact Social Security to start a DAC claim and provide medical evidence of the current disability.
