Social Security benefits for a child normally stop the month before the child turns 18. A full-time high school student can keep collecting until graduation or two months after turning 19, whichever comes first, and a child whose disability began before age 22 can continue receiving payments indefinitely on a parent’s work record. Marriage, certain earnings, and a failed SSI review at 18 can also cut payments off earlier.
The Default Cutoff Is Age 18
A child drawing benefits on a retired, disabled, or deceased parent’s record loses eligibility the month before turning 18, unless the child is a full-time student or has a qualifying disability.1eCFR. 20 CFR 404.352 – When Does My Entitlement to Child’s Benefits Begin and End? A child who turns 18 in July receives a final benefit for June.
One timing quirk trips families up. Social Security treats a child born on the first of the month as reaching the birthday in the prior month.2Social Security Administration. Retirement Age and Benefit Reduction So a child born August 1 is considered to turn 18 in July, and the last payable month is June rather than July.
Social Security sends a notice to the family about three months before the child’s 18th birthday explaining that benefits will end and what options remain.3Social Security Administration. Benefits for Children Watch for that letter, because the exceptions below all require paperwork.
Full-Time High School Students Can Collect Until 19
A child still in high school at 18 doesn’t have to give up benefits. A full-time student at an elementary or secondary school can keep receiving payments until graduation or two months after turning 19, whichever comes first.3Social Security Administration. Benefits for Children If the child turns 19 during a month when school is not in session, the last payable month is the month before the 19th birthday.4Social Security Administration. Frequently Asked Questions for Students
To count as full-time, the student must attend a school at the secondary level or below, be enrolled in a course lasting at least 13 weeks, and be scheduled for at least 20 hours a week. College coursework does not qualify. The student completes Form SSA-1372-BK, has a school official certify enrollment, and returns it to a local Social Security office. Changing schools means a new form with certification from the new school.4Social Security Administration. Frequently Asked Questions for Students
Summer Breaks
Payments continue through summer vacation if three things are true: the break is no longer than four months, the student was attending full-time immediately before it, and the student plans to return right after.4Social Security Administration. Frequently Asked Questions for Students A gap semester or a decision to leave school without re-enrolling ends benefits during that time.
Homeschooled Students
Home-schooled children can qualify if their state recognizes home schooling as a valid educational institution and the family complies with state requirements. The home school instructor signs Form SSA-1372-BK as the certifying school official. States may require a certificate of intent, documentation of mandated tests, proof of the instructor’s qualifications, and attendance records.5Social Security Administration. RS 00205.275 Home Schooling Compliance with state law is required even if the student is older than the state’s compulsory education age.
Disability Before Age 22 Removes the Cutoff
A child whose disability began before age 22 can keep collecting on a parent’s work record at any age, with no expiration, as long as the disability continues and the person remains unmarried.6Electronic Code of Federal Regulations. 20 CFR 404.350 – Who Is Entitled to Child’s Benefits? These payments are called Disabled Adult Child or Childhood Disability Benefits. The parent must be receiving retirement or disability benefits, or must have died, for the child to qualify.3Social Security Administration. Benefits for Children
This provision is easy to miss. A 40-year-old with a qualifying condition can collect on a retired parent’s record if the disability existed before age 22. Documenting when the disability began is what makes or breaks the claim, so gather medical records well before the 18th birthday.
Marriage generally ends these benefits, with one carve-out. If the disabled adult child marries someone who is also receiving certain Social Security benefits, such as another disabled adult child or a person collecting disability, neither person’s payments stop.7Social Security Administration. SSR 78-10c – Child’s Insurance Benefits, Termination, Marriage of Disabled Child Marrying someone who does not receive Social Security ends payments, even if that spouse has a disability of their own.
SSI Works Differently: The Age-18 Redetermination
Supplemental Security Income is a separate, needs-based program, and children on SSI face a distinct hurdle at 18. Social Security re-evaluates the young adult using adult disability standards rather than the childhood criteria they originally qualified under. The adult standard focuses on whether the person can earn a living; the childhood standard measures functional limitations in daily activities.8Social Security Administration. Qualifying for Benefit Continuation After You Turn 18 The adult test is harder to meet, and many young people lose SSI at this review.
There is a safety net. Under a provision known as Section 301, payments can continue even after a not-disabled finding if the person is actively participating in a vocational rehabilitation program, an individualized education plan (for those aged 18 through 21), a Ticket to Work program, or a Plan to Achieve Self-Support. Participation must have started before the month disability was found to have ended, and Social Security must determine that finishing the program will reduce the chance the person returns to the disability rolls.9Social Security Administration. Policy for Section 301 Payments to Individuals Participating in a Vocational Rehabilitation or Similar Program Getting enrolled before the redetermination is the difference between keeping payments and losing them.
Even after clearing the age-18 review, SSI recipients face Continuing Disability Reviews at least every three years for conditions expected to improve, and periodically for others. Payments end if a review finds the person is no longer disabled.10Social Security Administration. Continuing Disability Reviews
Marriage Ends Benefits and Usually for Good
For non-disabled children, marriage terminates Social Security child benefits regardless of age or student status. Benefits end the month before the month the child marries.11Social Security Administration. Child’s Benefits Termination of Entitlement A 17-year-old still in high school who gets married loses benefits immediately; the student rule doesn’t override the marriage rule.
The termination is usually permanent. A child whose benefits ended because of marriage cannot get re-entitled on the same parent’s record even after a divorce or the spouse’s death.12Social Security Administration. POMS RS 00203.015 – Requirements for Re-Entitlement to Child’s Benefits One narrow path remains: if the other parent has an eligible work record, the child could file for initial entitlement on that record, since divorce doesn’t block a first-time application.
An annulled marriage may undo the termination, but a voidable marriage that was valid under state law until a court declared it invalid generally does end benefits.13Social Security Administration. SSR 84-1 – Annulment of a Voidable Marriage, Effect on Entitlement to Benefits
Other Events That Cut Payments Off Early
Earnings
Disabled beneficiaries who consistently earn above the substantial gainful activity threshold lose payments. In 2026 that threshold is $1,690 per month for non-blind individuals and $2,830 per month for those who are blind.14Social Security Administration. Substantial Gainful Activity
Non-disabled child beneficiaries, such as students aged 18 to 19, face a different rule. In 2026, Social Security withholds $1 in benefits for every $2 earned above $24,480 per year.15Social Security Administration. 2026 Cost-of-Living Adjustment (COLA) Fact Sheet A child’s earnings affect only their own benefits, not those of other family members on the same record.16Social Security Administration. How Work Affects Your Benefits
Incarceration
A beneficiary convicted of a crime and confined for more than 30 continuous days has benefits suspended, with reinstatement possible starting the month after release.17Social Security Administration. What Prisoners Need to Know When a parent’s benefits are suspended for incarceration, a dependent child’s benefits continue as long as the child remains otherwise eligible.18Social Security Administration. Benefits After Incarceration: What You Need to Know
Stepparent Divorce
A stepchild collecting on a stepparent’s record loses benefits the month after a divorce between the stepparent and the child’s biological parent becomes final.11Social Security Administration. Child’s Benefits Termination of Entitlement This applies to divorces finalized in or after July 1996. A stepparent who legally adopted the child before the divorce keeps the child eligible as an adopted child on that record.
Before the 18th Birthday
Act on the notice Social Security mails about three months out. If the child is still in high school, submit the student certification form promptly to prevent a gap. If a disability began before age 22, make sure the medical file is complete before the birthday, because a strong record is what preserves eligibility as a disabled adult child.
Turning 18 also changes who receives the money. A child whose payments were managed by a parent as representative payee can begin receiving payments directly by showing the ability to manage their own finances.19Social Security Administration. Becoming an Adult Young adults with cognitive disabilities or similar conditions typically stay with a representative payee. For questions on any of this, call Social Security at 1-800-772-1213 or visit a local office.
For SSI recipients, the age-18 redetermination is where most cases fall apart. Enrolling in vocational rehabilitation or maintaining an individualized education plan before that review takes place is what preserves Section 301 protection if the adult disability standard isn’t met.
