Your SSDI Continues, But the Rules Change

When a child receiving Supplemental Security Income (SSI) or Social Security Disability Insurance (SSDI) turns 18, the benefit does not stop. However, the Social Security Administration treats you as an adult from that date forward, which means your income and resources are counted differently, your parents' income no longer affects your payment, and you may be required to report changes that did not matter before.

The specific change depends on which program you receive. If you get SSI (the needs-based program for disabled children with limited family resources), your payment may increase, decrease, or stay the same because your parents' income and resources stop counting against you. If you get SSDI (based on a parent's or guardian's work record), your payment amount typically stays the same, but you now have your own work history and earnings limit to track.

Social Security does not automatically send you a notice explaining this transition. You need to understand what happens on your 18th birthday so you do not miss a reporting requirement or lose benefits by accident.

Key Takeaways

  • Your SSI or SSDI payment continues after you turn 18, but Social Security counts your own income and resources instead of your parents'.
  • If you receive SSI, your payment may change because parental income no longer reduces your benefit; you must report this change to Social Security.
  • If you receive SSDI, your payment usually stays the same, but you become responsible for reporting your own earnings and any work you do.
  • You must notify Social Security within 10 days of turning 18 if your living situation, income, or household changes.
  • If you work, you can earn up to a certain amount per month before your benefit is reduced, and this limit is the same whether you receive SSI or SSDI.

How SSI Changes When You Turn 18

If you receive SSI as a child, your benefit is calculated using your parents' income and resources. On your 18th birthday, Social Security stops counting your parents' money. This means your own SSI payment is recalculated based only on your income and what you own.

For most young adults, this change increases the payment because parental income is no longer reducing it. However, if you have your own job or savings, your payment may decrease or stop entirely. Social Security will send you a notice showing your new payment amount, usually within one to two months after your birthday. If you do not receive a notice, call Social Security at 1-800-772-1213 to confirm your new amount.

You must report any change in your living situation within 10 days. If you move out of your parents' home, live with a friend, or move into a group home, tell Social Security when ready. Your payment amount can change based on where you live and who pays for your food and shelter.

How SSDI Changes When You Turn 18

If you receive SSDI as a child (sometimes called Disabled Adult Child benefits), your payment is based on a parent's or guardian's Social Security record. When you turn 18, your payment amount does not change automatically. You keep receiving the same monthly amount as long as you remain disabled and meet the other program rules.

The key difference is that you now have your own earnings record. If you work, Social Security tracks your wages against the Substantial Gainful Activity (SGA) limit, which is the amount of monthly income that suggests you are working at a level that counts as substantial work. In 2024, this limit is $1,550 per month for non-blind disabled workers, though this amount changes each year. If your earnings exceed this limit for nine months in a rolling 60-month period, Social Security may determine you are no longer disabled and end your benefits.

You do not lose SSDI when ready if you earn above the SGA limit. Instead, Social Security reviews your case and may schedule a medical review to determine whether you still meet the disability standard. Report your earnings to Social Security as soon as you know they will exceed the limit.

Reporting Requirements and important date

After you turn 18, you become responsible for reporting changes to Social Security yourself. Your parents can no longer report on your behalf unless you give Social Security written permission for them to act as your representative.

You must report within 10 days if any of the following happen: you start or stop working, your income changes, you move to a new address, your living situation changes (such as moving in with a friend or into a group home), you marry, you have a child, or you are arrested or convicted of a crime. Failure to report can result in an overpayment — money Social Security paid you that you were not may have access to to — which you will be required to repay.

The easiest way to report is online through your my Social Security account at ssa.gov. You can also call 1-800-772-1213 or visit your local Social Security office in person. Keep a record of the date you reported and the name of the person you spoke with.

Work Incentives and Earnings Rules

Both SSI and SSDI have work incentives designed to let you earn money without losing your entire benefit when ready. However, the rules are different for each program.

If you receive SSI, you can earn up to $65 per month without any reduction to your benefit. After that, Social Security counts half of your remaining earnings against your payment. For example, if you earn $200 per month, Social Security subtracts $65 (the disregard), leaving $135. Half of $135 is $67.50, which reduces your SSI payment by that amount. You can also set aside money in a Plan to Achieve Self-Support (PASS), which lets you exclude certain income and resources from the SSI calculation if you are working toward a specific job goal.

If you receive SSDI, you can earn up to $1,550 per month (in 2024) without triggering a medical review. However, Social Security still tracks your earnings. If you consistently earn above this amount, Social Security will review whether you are still disabled. You may also be may have access to to a Trial Work Period, which lets you test your ability to work for nine months without any reduction to your SSDI payment, as long as you report your earnings.

Medical Reviews and Continuing Disability

When you turn 18, Social Security may schedule a medical review to determine whether you still meet the disability standard for adults. This is separate from the age-18 transition and can happen at any time, but it is common in the months before or after your birthday.

For this review, you will receive a notice asking you to submit medical evidence — recent doctor's reports, test results, or hospital records showing your current condition. You must respond within the important date given in the notice, usually 10 days. If you do not respond, Social Security may stop your benefits.

If you disagree with the decision, you can request reconsideration within 60 days. You have the right to submit new medical evidence, ask for a hearing before an Administrative Law Judge, or appeal further. Many people find it helpful to work with a benefits planning information program or a disability advocate during this process.

What to Do Before Your 18th Birthday

Start preparing for the transition at least one month before you turn 18. Gather recent medical records and make sure your doctor has current information about your condition. If you plan to work, research the earnings rules for your program and understand how much you can earn without triggering a benefit reduction or medical review.

If your parents have been managing your Social Security account, ask them to help you set up a my Social Security account in your own name at ssa.gov. This account lets you view your payment history, report changes, and receive notices from Social Security online. You can also authorize your parents or a trusted adult to be your representative payee if you need help managing your benefits, though this requires a formal request to Social Security.

If you receive SSI and your family's income situation is complex, ask Social Security whether a PASS plan might help you if you plan to work. A PASS plan can protect more of your earnings and resources, but it must be set up before you turn 18 or shortly after.

Frequently Asked Questions

Will my payment stop when I turn 18?

No. Your SSI or SSDI payment continues after you turn 18 as long as you remain disabled and meet the other program rules. The amount may change, especially for SSI, because your parents' income no longer counts, but the benefit itself does not end on your birthday.

What if I want to go to college or vocational school?

You can attend school and keep your SSI or SSDI. If you receive SSI, student earned income is treated more favorably than other income — you can exclude up to $7,770 per year (in 2024) if you are a full-time student under age 22. If you receive SSDI, school attendance does not affect your payment, but work you do while in school is still subject to the SGA limit.

Can my parents still help me manage my benefits after I turn 18?

Yes, if you authorize them. You can name your parents as your representative payee, which lets them receive and manage your benefit payment on your behalf. You can also give them power of attorney to handle Social Security matters. Both require written authorization to Social Security.

What happens if I do not report a change in my income or living situation?

Social Security may overpay you — send you more money than you were may have access to to receive. You will be required to repay the overpayment, which can happen through benefit reduction, a payment plan, or a demand letter. Reporting changes within 10 days prevents this.

Do I need a lawyer to handle my benefits after I turn 18?

You do not need a lawyer, but you may find it helpful to work with a disability advocate or benefits planning information program, especially if you plan to work or if Social Security schedules a medical review. Many programs offer free or low-cost help. Ask your local Social Security office for referrals.
