Whether your child qualifies for SSI comes down to two tests applied together: a medical test showing the child has a severe, long-lasting disability, and a financial test showing your family’s income and assets fall below federal limits. Neither test alone is enough. A child with a serious diagnosis in a middle-income household often won’t qualify, and a low-income child without a qualifying impairment won’t either. In 2026, a child who passes both tests can receive up to $994 a month in federal SSI, plus a state supplement in some places.1Social Security Administration. 2026 Cost-of-Living Adjustment (COLA) Fact Sheet
Who Counts as a Child
SSI treats anyone under 18 as a child. The definition stretches to age 22 if the person is unmarried, not the head of a household, and regularly attending school or job training.2eCFR. 20 CFR 416.1856 – Who Is Considered a Child
The child must live in the United States, meaning the 50 states, the District of Columbia, or the Northern Mariana Islands, and must be a U.S. citizen or national. Some lawful permanent residents and other noncitizens qualify if they meet specific immigration criteria.3eCFR. 20 CFR Part 416 Subpart B – Eligibility
The Medical Test
For SSI, a child is disabled if they have a physical or mental impairment, or a combination of impairments, that causes “marked and severe functional limitations” and is expected to last at least 12 continuous months or result in death.4eCFR. 20 CFR Part 416 Subpart I – Definition of Disability This is a different standard than the one used for adults, which asks whether a person can work.
Matching a Listed Impairment
The SSA’s Listing of Impairments, commonly called the Blue Book, catalogs medical conditions that automatically meet the disability standard. Part B covers childhood conditions, organized by body system: musculoskeletal, neurological, cardiovascular, immune, and others.5Social Security Administration. Disability Evaluation Under Social Security If your child’s condition matches a listing, or is medically equivalent to one, the medical test is satisfied.
Functionally Equaling a Listing
Many children who don’t fit neatly under a listing still qualify. The SSA evaluates how the impairment affects the child’s day-to-day functioning across six domains:6Social Security Administration. Code of Federal Regulations 416.926a
- Acquiring and using information
- Attending and completing tasks
- Interacting and relating with others
- Moving about and manipulating objects
- Caring for yourself
- Health and physical well-being
To functionally equal a listing, the child must have “marked” limitations in at least two domains, or an “extreme” limitation in one. The comparison is against what is typical for children of the same age who do not have impairments. Medical records, therapy notes, school evaluations, IEPs, and reports from teachers and caregivers all feed into this analysis, which is why school records matter as much as medical ones.
The Financial Test
Because a child under 18 rarely has independent income, the SSA applies “deeming,” treating a portion of the parents’ income and resources as available to the child.7Social Security Administration. Understanding SSI – SSI for Children Not every dollar counts. The agency subtracts allowances for each parent and each non-disabled child in the home before deeming anything to the applying child. Some income is never deemed at all, including TANF payments, certain VA pensions, and court-ordered support the parent is paying out.8Social Security Administration. SSI Spotlight on Deeming Parental Income and Resources
Income
SSI looks at earned income (wages, self-employment) and unearned income (Social Security benefits, pensions, unemployment, interest). As a rough guideline, a family is unlikely to qualify if a single working parent earns more than about $2,073 a month, but the actual cutoff depends on household size, whether one or two parents live in the home, and whether any unearned income is also present.9Social Security Administration. Who Can Get SSI A two-parent home with several children has a higher threshold than a single parent with one child, because the allowance subtracted before deeming is larger.
If the child has their own earnings, such as a teenager with a part-time job, the SSA applies a student earned income exclusion. In 2026, up to $2,410 per month, and no more than $9,730 for the year, of a student’s earnings is disregarded.10Social Security Administration. Student Earned Income Exclusion for SSI
Resources
The SSA also counts assets, called “resources”: cash, bank accounts, stocks, bonds, life insurance, and real estate other than your primary home. One vehicle used for transportation is fully excluded regardless of value; additional vehicles count at equity value.11eCFR. 20 CFR Part 416 Subpart L – Resources and Exclusions The 2026 resource limit is $2,000 for an individual and $3,000 for a couple.1Social Security Administration. 2026 Cost-of-Living Adjustment (COLA) Fact Sheet Under deeming, parental resources count only to the extent they exceed the applicable limit.
ABLE Accounts
Families whose child’s disability began before age 26 can use an ABLE (Achieving a Better Life Experience) account to save above the usual limit. Up to $100,000 in an ABLE account is excluded from the SSI resource count.12Social Security Administration. POMS SI 01130.740 – Achieving a Better Life Experience (ABLE) Accounts A balance above $100,000 does count, and SSI payments are suspended, though not terminated, until the balance drops back below the threshold.
What Approval Means
The maximum federal SSI payment for an eligible child in 2026 is $994 per month.1Social Security Administration. 2026 Cost-of-Living Adjustment (COLA) Fact Sheet The actual payment depends on how much countable income remains after exclusions and deeming. Countable income reduces the payment dollar for dollar. Some states add a supplement, which varies by state and living arrangement.13Social Security Administration. How Much You Could Get From SSI
In most states, a child approved for SSI is automatically eligible for Medicaid, with no separate application, under Section 1634 of the Social Security Act.14Social Security Administration. Social Security Act Section 1634 A few states use different Medicaid eligibility criteria for SSI recipients, so check with your state’s Medicaid office if you’re unsure.
Initial disability decisions generally take six to eight months.15Social Security Administration. How Long to Get a Decision for Disability Benefits16Social Security Administration.

Qualifying Now Doesn’t Mean Qualifying Forever
SSI approval is not permanent. The SSA schedules continuing disability reviews at least every three years for children whose condition may improve, and reviews infants who qualified based on low birth weight before age one.17Social Security Administration. Continuing Disability Reviews
The bigger checkpoint comes at age 18. Within one year of the child’s 18th birthday, the SSA redetermines eligibility using the adult disability standard, which asks whether the person can perform substantial gainful activity rather than whether they have marked and severe functional limitations.18Social Security Administration. Code of Federal Regulations 416.987 – Disability Redeterminations for Individuals Who Attain Age 18 Some children who qualified as minors will not qualify as adults. If the redetermination goes against the individual, appealing within 10 days and requesting continued payments keeps benefits flowing during the appeal. Separately, Section 301 of the Social Security Act allows payments to continue for someone already participating in a vocational rehabilitation program, an IEP, or a similar career-preparation program before the cessation decision, provided the SSA is notified about the program at the start of the redetermination.19Social Security Administration. Section 301 – SBC
If the Application Is Denied
Denials are appealable. You have 60 days from receipt of the decision to request reconsideration, and 60 days at each subsequent level: reconsideration, a hearing before an Administrative Law Judge, Appeals Council review, and federal district court.20Social Security Administration. Code of Federal Regulations 404.911 Missing a deadline can end your appeal rights. Many families qualify for free representation through legal aid organizations; the Legal Services Corporation website lists local providers, and your Social Security field office can also refer you.
