The numbers that matter for childhood SSI
Here's what to do, in 4 steps.
Here's the order I'd work in if I were sitting at your kitchen table tonight. The application is its own task. The records you collect now will matter again at age eighteen.
-
Apply for SSI on your child's behalf
Start at ssa.gov or call 1-800-772-1213. The disability application includes medical questionnaires (Form SSA-3820) and parent-deeming detail. Have your child's medical records, school IEPs, and your tax return on hand.
Time: 1–2 hours initial; 3–6 months for decision Cost: Free SSA child disability starter kit
-
Gather medical records, evaluations, and IEPs
SSA needs evidence of marked and severe functional limitations. Pediatricians, specialists, therapists, and the school IEP team all generate documentation that strengthens the case. Don't wait — schools are slow to release records.
Time: 2–6 weeks Cost: Free (request copies) POMS DI 25201.001 — child disability evidence
-
Save every record — you'll need them at age 18
Continuous documentation matters. The age-eighteen redetermination uses the adult standard, and the case is much easier to win if you've been collecting evaluations and treatment notes the whole way through.
Time: Ongoing Cost: Free 20 CFR 416.987 (age-18 redet)
-
Prepare for the age-18 redetermination 6+ months early
About 30–40% of childhood SSI recipients lose benefits at the age-18 review because the adult standard is stricter. Start documenting your teen's adult-level functional limitations — work, daily living, social functioning — well before the eighteenth birthday. Consider a disability attorney if a denial seems likely.
Time: Begin 6–12 months before age 18 Cost: Free (attorneys take fee from back pay) 20 CFR 416.987 (age-18 redet)

I'm filming a walkthrough of the childhood disability rules — the six functional domains, the age-eighteen cliff, and what to bring to the application.
Which of these sounds more like you?
Pediatric SSI cases come in patterns. Pick the one closest to your situation.
My child has autismASD with documented functional impact
Many children with autism qualify under Listing 112.10 (Autism Spectrum Disorder, childhood) or by functional equivalence across the six domains. The IEP and school evaluations are gold here — they document exactly what SSA wants to see.
Gather speech and OT evaluations, behavioral evaluations, the most recent IEP, and any private psychological testing. SSA will look at how your child interacts with others, completes tasks, and cares for themselves compared to age-typical peers.
My child has Down syndromeTrisomy 21 — typically meets a listing
Children with non-mosaic Down syndrome typically meet Listing 110.06 (chromosomal disorders) on documentation alone — the genetic test result is the medical evidence. Mosaic Down syndrome is evaluated on functional impact under Listing 112.06 or by functional equivalence.
Bring the karyotype or chromosomal analysis report. The financial side (parent deeming, the SSI federal benefit rate, dedicated accounts for retroactive pay) is usually the bigger question for these families.
My child has serious behavioral issuesMental disorders, ADHD, conduct, mood
Listings 112.04–112.15 cover childhood mental disorders — mood, anxiety, ADHD, conduct, psychotic, and others. Many cases come down to functional equivalence rather than meeting a listing on the dot, because childhood mental conditions cross domains.
The key is documenting marked limitation in two domains or extreme in one — commonly interacting with others, attending to tasks, and caring for self. School discipline records, behavioral therapy notes, and psychiatric evaluations all matter.
We earn too much for SSIOr do you? Deeming has exclusions
Parent-to-child deeming reduces SSI based on parent income and resources, but the math has many exclusions: a portion of earned income, child support paid out, allowances for other children in the household, and more. Many families assume they're disqualified when they actually aren't.
Apply anyway. The denial letter, if it comes, will spell out the exact deeming math — and you may find a deduction or exclusion you missed.
My teen is turning 18 soonThe age-18 redetermination cliff
At 18, SSA redetermines disability using the ADULT standard — a stricter test that focuses on the ability to perform substantial gainful activity. About 30–40% of childhood SSI recipients lose benefits at this point.
Deeming also stops at 18, which sometimes increases the SSI payment for those who keep eligibility. If your teen is denied, file an appeal within sixty days — do not wait.
My child got approved — back pay is comingDedicated account rules apply
When SSA owes a child more than one thousand dollars in retroactive SSI, the money must go into a dedicated account at a financial institution. Funds can only be used for medical and educational expenses, special equipment, housing modifications, and certain therapies.
The representative payee (usually the parent) tracks every withdrawal. SSA may audit the account. Keep receipts.
I'm caring for a niece, nephew, or grandchildCustody, deeming, and rep-payee rules
If you have legal custody or guardianship of a child who isn't yours, SSI is still on the table for them. Whose income gets deemed depends on the legal arrangement: a guardian's income may not be deemed at all, while a stepparent's typically is.
You'll likely need to be the representative payee — the person who manages the child's SSI on their behalf. SSA reviews payee performance annually.
My situation isn't covered aboveTalk to someone who has the full picture
Pediatric SSI cases come in patterns, but every family is different. If your situation doesn't match any of the cards above, that doesn't mean your child doesn't qualify — it means a phone call to SSA or a free consultation with a disability attorney is the next move.
SSA's national line is 1-800-772-1213. Many disability attorneys offer free initial consultations and only charge if your case wins.
Everything parents ask me
What's the disability standard for children on SSI?
Per 20 CFR § 416.906, a child under 18 is disabled for SSI if they have a medically determinable physical or mental impairment that causes "marked and severe functional limitations" and that has lasted or can be expected to last at least 12 continuous months (or to result in death). This is more restrictive than the adult standard, which focuses on inability to perform substantial gainful activity.
What are the 6 functional domains?
Per 20 CFR § 416.926a and POMS DI 25225.001, when a child doesn't meet a listing, SSA evaluates functional equivalence across six domains: (1) Acquiring and using information; (2) Attending and completing tasks; (3) Interacting and relating with others; (4) Moving about and manipulating objects; (5) Caring for yourself; (6) Health and physical well-being. "Marked" limitation in two domains OR "extreme" limitation in one domain functionally equals a listing.
What is parent-to-child deeming?
Deeming is the rule that treats some of a parent's income and resources as if they belong to the child for SSI purposes (POMS SI 01310). The deeming math reduces or eliminates SSI based on parent finances, but it includes substantial exclusions — part of earned income, allowances for non-disabled siblings, child support paid out, and more.
What happens at age 18?
Per 20 CFR § 416.987, SSA conducts an age-18 redetermination using the adult disability standard — a stricter test focused on inability to perform substantial gainful activity. About 30–40% of childhood SSI recipients lose benefits at this review. Deeming also stops at 18, which sometimes increases the SSI payment for those who keep eligibility.
Can my child still get Medicaid if they lose SSI at 18?
Possibly. Section 1619(b) preserves Medicaid for some people who lose SSI due to earnings. Your state may also have a separate Medicaid pathway for adults with disabilities, and Disabled Adult Child (DAC) status on a parent's record can include Medicaid in some states. Talk to your state Medicaid office before assuming Medicaid stops.
What is a dedicated account?
Per POMS SI 02101.020 and 42 USC § 1383(a)(2)(F), when SSA owes a child more than $1,000 in retroactive SSI, the money must go into a dedicated account at a financial institution. Funds can only be used for medical care, education, special equipment, housing modifications, and certain therapies. The representative payee tracks every withdrawal; SSA may audit.
Does my child's IEP help the SSI application?
Yes. The Individualized Education Program (IEP) and any school evaluations document functional limitations across exactly the kinds of areas SSA reviews — academic performance, social interaction, attention, self-care. Bring the most recent IEP plus any related psychological, speech, or OT evaluations to your application.
Can a child receive both SSI and child support?
Yes, but child support counts as unearned income to the child and reduces SSI. Per 20 CFR § 416.1124(c)(11), one-third of child support payments is excluded; the remaining two-thirds reduces SSI dollar-for-dollar after the general $20 unearned income exclusion.
Does my child get Medicaid automatically with SSI?
In 1634 states (about thirty-three states), yes — SSI eligibility automatically establishes Medicaid. In 209(b) states, you may need to apply separately because the state uses its own (sometimes stricter) Medicaid disability rules. Even if your child loses SSI at age 18, the Medicaid history can matter — some states have special pathways that preserve Medicaid for adults who had SSI as children.
Can I appeal a denial?
Yes. The same four-level appeal process applies as in adult cases: reconsideration, ALJ hearing, Appeals Council, federal court. The deadline is 60 days at each level. Pediatric SSI denials have notable reversal rates at the ALJ level — don't give up after the first denial.
Other programs your family may qualify for
SSI rarely stands alone for a child with a disability. Medicaid, CHIP, special education services, and ABLE accounts often run alongside.
Disabled Adult Child (DAC)
If your child's disability began before age twenty-two and a parent later files for retirement or disability — or dies — your adult child may qualify for DAC benefits on the parent's record. DAC benefits do not have an asset test and may be substantially higher than SSI.
Medicaid (children's pathway)
Most children on SSI get Medicaid automatically (in 1634 states). Children who don't qualify for SSI may still qualify for Medicaid through the children's MAGI pathway, which uses different income rules.
CHIP (Children's Health Insurance Program)
If your family income is too high for Medicaid but you can't afford private insurance, your child may qualify for CHIP. State-administered; income limits vary.
SNAP (food assistance)
Households with a child receiving SSI often qualify for SNAP. Some states have streamlined SNAP enrollment for SSI households.
ABLE accounts
Tax-advantaged savings accounts for individuals whose disability began before age forty-six (per SECURE 2.0, effective 2026). Funds in an ABLE account up to one hundred thousand dollars don't count against the SSI resource limit.
Special education / IEP services
Under IDEA, your child has a federal right to a free appropriate public education with an Individualized Education Program (IEP) or 504 plan. The IEP also documents functional limitations — useful evidence for the SSI case.
