The application process starts with Social Security, not your doctor

To apply for Supplemental Security Income (SSI) for a child with autism, you contact Social Security directly — by phone, in person at a local office, or online through their website. Social Security will ask for medical records, school records, and proof of your household income and resources. The process typically takes three to six months from application to a decision, though it can be longer if Social Security asks for additional information.

You do not need a diagnosis letter from your child's doctor to start. You do need to show that your child has a condition that significantly limits their ability to function — autism alone does not automatically may have access to. Social Security will review what your child can and cannot do: can they communicate, follow directions, care for themselves, attend school, interact with others. The medical and school records you submit become the evidence for that review.

Key Takeaways

  • You apply through Social Security by calling 1-800-772-1213, visiting your local office, or going to ssa.gov; the process takes three to six months.
  • You will need your child's birth certificate, Social Security number, medical records from doctors or therapists who have treated your child, school records or IEP, and proof of your household income and bank balances.
  • Social Security looks at whether your child's autism limits their ability to function in daily life — not just the diagnosis itself — so detailed records of what your child struggles with matter more than the label.
  • If Social Security denies your application, you can request reconsideration within 60 days; many families are denied the first time and approved on reconsideration or appeal.

What documents you need to gather before you call

Have these items ready before you contact Social Security. You will not need all of them immediately, but having them organized speeds up the process and prevents delays later.

Identity and citizenship documents: Your child's birth certificate and Social Security number. If your child does not have a Social Security number yet, Social Security can assign one during the application. You will also need your own ID and Social Security number, since you are the parent or guardian applying on your child's behalf.

Medical records: Any evaluations, diagnoses, or treatment summaries from doctors, psychologists, developmental pediatricians, or therapists who have worked with your child. Autism evaluations are especially important — include the full report if you have one, not just a letter saying your child has autism. Records should show when your child was evaluated, what specific behaviors or abilities were tested, and what the results were. If your child takes medication, include a list of current medications and what they treat.

School records: Your child's Individualized Education Program (IEP) if they have one, or a recent report card and teacher comments if they do not. The IEP is the most useful document because it lists the specific areas where your child needs support — communication, social skills, self-care, behavior — and shows what accommodations or services the school provides. If your child receives speech therapy, occupational therapy, or other services through school, include those records too.

Financial documents: Recent bank statements (usually the last two months), proof of income for all household members (pay stubs, tax returns, or a letter from your employer), and a list of any other resources like savings accounts or property. Social Security has income and resource limits; the limits vary by state but are roughly $2,000 in resources and $1,000 per month in income for a child living with parents.

How to start the application

You have three ways to apply: by phone, in person, or online.

By phone: Call Social Security at 1-800-772-1213 (TTY 1-800-325-0778 for deaf or hard of hearing). Tell them you want to apply for SSI for your child. They will schedule an appointment — either a phone interview or an in-person appointment at your local Social Security office. The wait time to reach someone can be long, especially early in the day; calling mid-morning or mid-afternoon often has shorter hold times.

In person: Visit your local Social Security office. You can find the address and hours on ssa.gov by entering your zip code. Bring your documents with you, or bring copies and leave them with the office. You do not need an appointment in most offices, but calling ahead to ask about wait times is common practice.

Online: You can start an application on ssa.gov under "Apply for Benefits." The online application asks basic questions about your child and your household. You will still need to provide documents and have an interview with Social Security, but starting online can shorten the overall timeline. After you submit the online application, Social Security will contact you to schedule an interview.

What happens during the interview

Social Security will ask detailed questions about your child's daily life: how your child communicates, whether they can dress or bathe themselves, how they behave around other children, whether they attend school and how they perform, what activities they can do independently, and what tasks require your help. They will also ask about your household income, who lives with your child, and whether your child receives any other benefits.

Bring your documents to the interview or have them ready if the interview is by phone. Social Security will make copies or ask you to mail them in. Be specific in your answers — instead of saying "my child has trouble with social skills," describe what that looks like: "my child does not make eye contact, does not respond when other children try to talk to them, and becomes upset in crowded places." The more concrete your descriptions, the clearer the picture Social Security has of how autism affects your child.

After the interview, Social Security sends your case to a medical reviewer who reads all the documents and decides whether your child meets the criteria for SSI. This part of the process usually takes one to three months. Social Security will mail you a decision letter.

What happens if Social Security says no

Many families receive a denial the first time. This does not mean your child does not may have access to — it often means Social Security needs more information or a clearer picture of your child's limitations.

You have 60 days from the date on the denial letter to request reconsideration. This means Social Security will review your case again, usually with a different medical reviewer. You can submit new documents during reconsideration — updated medical records, a new school evaluation, or a letter from your child's doctor describing how autism affects your child's functioning. Many families are approved on reconsideration.

If reconsideration is also denied, you can request a hearing before an administrative law judge. This is a more formal process where you can present evidence and argue your case. You can represent yourself or hire a lawyer. Many families win at the hearing stage. If you hire a lawyer, they typically take a percentage of your back pay (the money owed from the date you first applied) rather than charging you upfront.

Income and resource limits that affect your child

SSI has strict income and resource limits. If your household income or resources are too high, your child will not be approved, even if they have a severe disability.

Resource limits are usually around $2,000 for a child. Resources include cash, bank accounts, stocks, and property — but not your home or one car. Income limits vary by state but are roughly $1,000 per month for a child. Income includes wages, child support, and some benefits, but not all income counts the same way. Social Security has rules about what counts and what does not.

If your household income is over the limit, your child may still be able to receive SSI through something called a "deemed income" calculation, which counts only part of your household income toward your child's limit. The rules are complex; ask Social Security to explain how your specific income will be counted.

What your child receives if approved

If approved, your child receives a monthly cash payment and Medicaid. The monthly payment amount varies by state — it is usually between $600 and $900 per month, though some states add a small supplement. The payment goes to you as the parent or guardian, and you use it for your child's needs.

Medicaid covers medical care, therapy, medications, and some services that regular health insurance does not cover. Many children with autism use Medicaid to pay for speech therapy, occupational therapy, behavioral therapy, or other treatments. Medicaid coverage varies by state, so ask your state Medicaid office what services are covered for children with autism.

Your child can continue to receive SSI through age 18. At 18, Social Security will do a new review to see if your child still meets the criteria. If your child is still disabled and your household income is still low enough, SSI continues. If your child turns 18 and no longer meets the criteria, the payments stop.

Frequently Asked Questions

Does my child need a formal autism diagnosis to apply?

Yes. Social Security needs medical documentation that your child has autism, usually from a psychologist, developmental pediatrician, or neurologist who has evaluated your child. A school evaluation or a letter from a teacher is not enough on its own. If your child has been evaluated but you do not have the full report, contact the evaluator's office and request a copy.

Can I apply if my child is in regular school and doing okay academically?

Yes. SSI is not based on school performance or IQ alone. It is based on whether your child's autism significantly limits their ability to function in daily life — communication, self-care, social interaction, behavior, or independence. A child can be academically average but still struggle with social skills, sensory issues, or self-regulation enough to meet SSI criteria.

What if I have never worked or do not have recent tax returns?

Social Security can work with other proof of income: recent pay stubs, a letter from your employer, bank statements showing regular deposits, or a statement from a benefits program you receive. If you have no income, bring documentation of that — a statement from your employer saying you are not currently employed, or a letter explaining your situation. Social Security needs to know your household's financial situation, but they understand that not everyone has formal tax returns.

How long does my child stay on SSI?

Your child can receive SSI until age 18. At 18, Social Security reviews your child's case again to see if they still meet the criteria for disability. If your child continues to have autism that limits their functioning, your child may move to Social Security Disability Insurance (SSDI) or continue on SSI as an adult, depending on your household income and your child's situation at that time.

What if my child's condition improves or they no longer need services?

You must report changes to Social Security. If your child's condition improves significantly or you no longer think they meet the criteria, tell Social Security. They may stop your child's benefits or schedule a review. If you do not report changes and Social Security finds out later, you may have to repay benefits your child received while no longer meeting the criteria.
