To apply for SSI for a child, call the Social Security Administration at 1-800-772-1213 or contact your local field office to start the claim; there is no fully online application for child SSI. A parent or guardian schedules an interview, completes the Child Disability Report, and provides medical, school, and financial records showing that the child has a severe qualifying disability and that the household’s income and resources fall below the program’s limits.
Start by Calling Social Security
The first move is a phone call, not paperwork. Call 1-800-772-1213 Monday through Friday, 8:00 a.m. to 7:00 p.m. local time, or contact your local Social Security office directly.1Social Security Administration. Contact Social Security By Phone Tell the representative you want to apply for SSI for your child. That contact can establish a protective filing date, which the SSA treats as your application date even if the full paperwork and interview take weeks to complete.2SSA – POMS. SI 00601.009 – Application Effective Date
Benefits can begin as early as the first day of the month after your application is filed, or the month after the child becomes eligible, whichever is later. Any gap between your first contact and a completed application can cost a month of benefits, so call as soon as you think your child may qualify. Don’t wait until every document is in hand.
Gather the Documents Before the Interview
The SSA publishes an SSI Child Disability Starter Kit that walks families through what to collect.3Social Security Administration. Disability Starter Kits Plan on assembling three kinds of records.
Medical Records
Compile the names, addresses, and phone numbers of every healthcare provider who has treated your child. Build a chronological list of doctor visits, hospitalizations, surgeries, and therapy sessions tied to the impairment, and include a complete list of current medications with dosages. This information feeds directly into the Child Disability Report (Form SSA-3820-BK), which asks how the condition affects daily activities compared to other children the same age.4Social Security Administration. Disability Report – Child – SSA-3820-BK
School Records
Educational records show how the child functions in a structured setting that medical files often miss. The SSA routinely requests Individualized Education Programs (IEPs) and Section 504 plans, academic performance records, psychological evaluations, attendance history, and standardized testing results.5Social Security Administration. Childhood Disability SSI Program – Guide for School Professionals Written observations from teachers about behavior, attention, and task completion also help.
Financial Records
Because SSI is need-based, the representative will ask about household finances. Have recent pay stubs, tax returns, bank statements, and information about any other assets ready. If a stepparent lives in the home, their income and resources come into the calculation too.
Complete the Interview and the Child Disability Report
You can fill out the Child Disability Report online ahead of time to create a digital record of your child’s medical history, but the actual application requires an interview with a Social Security representative by phone, video, or in person. During that interview the representative reviews your financial documents, verifies household information, and submits the completed application into the federal system.
Whether Your Household Income and Resources Qualify
Financial eligibility runs on a process called deeming, which counts a portion of the parents’ income and resources as though they belong to the child.6eCFR. 20 CFR Part 416 Subpart K – Deeming of Income Not every dollar counts. The SSA subtracts $20 from unearned income (or from earned income if unearned income is less), then subtracts $65 plus half of any remaining earned income. It also subtracts an allocation equal to the federal benefit rate for each parent and an allocation for each other ineligible child in the household. Only what remains after these deductions is deemed to the child.7Social Security Administration. 20 CFR 416.1165 – How We Deem Income to You From Your Ineligible Parents Many working families with modest incomes still qualify.
Countable resources must stay below $2,000 for an individual or $3,000 for a couple.8Social Security Administration. 2026 Cost-of-Living Adjustment (COLA) Fact Sheet Countable resources include bank accounts, stocks, bonds, cash value life insurance, and property beyond the primary home. Several important assets are excluded: the family’s primary home and the land it sits on don’t count regardless of value, and one vehicle used for transportation is fully excluded.9Social Security Administration. SSI Resources
An ABLE (Achieving a Better Life Experience) account gets special treatment. The SSA disregards the first $100,000 in an ABLE account, so only balances above that threshold count toward the resource limit.10Social Security Administration. Spotlight On Achieving A Better Life Experience (ABLE) Accounts The annual contribution limit is $19,000 in 2026, with a higher cap available to employed account holders in some circumstances.
What Counts as a Qualifying Childhood Disability
The disability standard for children differs from the adult standard. A child must have a medically determinable physical or mental impairment that causes “marked and severe functional limitations,” meaning the condition significantly restricts the child’s ability to do things typical for their age. The condition must have lasted, or be expected to last, at least 12 continuous months or be expected to result in death.11Office of the Law Revision Counsel. 42 USC 1382c – Definitions
The SSA evaluates cases using childhood-specific medical criteria called the Listing of Impairments, or Blue Book. The childhood listings cover 15 categories including low birth weight, musculoskeletal disorders, respiratory disorders, neurological disorders, mental disorders, cancer, and immune system disorders.12Social Security Administration. Listing of Impairments – Child Listings (Part B) A child whose condition meets or medically equals a listing qualifies. If the condition does neither, the SSA looks at whether it “functionally equals” a listing by causing extreme limitation in one area of functioning or marked limitations in two.
A child receiving SSI also cannot earn above the substantial gainful activity threshold, which is $1,690 per month in 2026.13Social Security Administration. Substantial Gainful Activity For SSI purposes, a “child” is someone under 18 who is not married and not the head of a household, though students regularly attending school may qualify up to age 22.14Social Security Administration. SSI for Children
Faster Payments for Certain Severe Conditions
Some children qualify for immediate SSI payments while the formal disability review is still pending. These presumptive disability payments can last up to six months and are paid at the regular SSI amount.15SSA – POMS. DI 23535.001 – Presumptive Disability and Presumptive Blindness Categories the field office can approve on the spot include:
- Down syndrome
- Intellectual disability or another neurodevelopmental condition such as autism spectrum disorder, with complete inability to independently perform basic self-care activities like eating, dressing, or bathing, in children at least 4 years old
- Infants under 1 year old with a birth weight below 1,200 grams (about 2 pounds, 10 ounces)
- Infants under 1 year old who meet specific combinations of gestational age and birth weight
- Symptomatic HIV or AIDS
- Terminal illness with a life expectancy of six months or less, confirmed by a physician or evidenced by hospice services16SSA – POMS. Field Office Presumptive Disability and Presumptive Blindness Categories Chart
If your child fits one of these categories, tell the representative during your first call.
What Happens After You File
The SSA sends the case to your state’s Disability Determination Services (DDS) office for the medical review. DDS physicians and psychologists examine the evidence you submitted. If existing records aren’t enough for a clear decision, DDS may schedule a consultative examination, an independent medical evaluation paid for by the government.17Social Security Administration. Disability Determination Process Your child must attend any consultative examination that is scheduled; skipping it can result in a denial.
An initial decision generally takes six to eight months from the date you filed.18Social Security Administration. How Long Does It Take to Get a Decision After I Apply for Disability Benefits The SSA mails an official notice either awarding benefits or denying the claim, and a denial letter explains the reasons and your appeal rights.
The maximum federal SSI payment for an eligible individual in 2026 is $994 per month.19Social Security Administration. SSI Federal Payment Amounts for 2026 Your child’s actual payment may be lower if countable household income remains after deeming. Many states add a supplemental payment on top of the federal amount, ranging from a few dollars to several hundred dollars per month. Ask your state’s social services agency whether a supplement is available where you live.
If the Claim Is Denied
You have 60 days from the date you receive the denial notice to appeal. The SSA assumes you received the notice five days after it was mailed, so the practical deadline is 65 days from the mailing date.20Office of the Law Revision Counsel. 42 USC 1383 – Procedure for Payment of Benefits Missing the deadline can mean starting the whole application over.
The first appeal level is reconsideration by a different DDS reviewer. If that is also denied, you can request a hearing before an administrative law judge, and further review by the Appeals Council and federal court is available after that.21Social Security Administration. Understanding Supplemental Security Income Appeals Process Most successful claims are won at the hearing stage. You can represent yourself or hire a representative; under an SSA-approved fee agreement, the representative’s fee cannot exceed 25 percent of past-due benefits or $9,200, whichever is less, and is paid from back benefits rather than out of pocket.22Social Security Administration. Fee Agreements
One Boundary: The Age-18 Redetermination
Children approved for SSI don’t stay on the childhood standard forever. During the one-year period beginning on the child’s 18th birthday, the SSA is required to redetermine eligibility using the adult disability standard, which asks whether the person is unable to perform any substantial gainful activity because of a qualifying impairment.23SSA – POMS. Requirements for an Age-18 Redetermination Some children who qualified under the childhood standard will not meet the adult standard.24Social Security Administration. The Age-18 Redetermination and Postredetermination Participation in SSI Keep medical records, IEPs, and any Section 504 plan current as that milestone approaches.
