What You Need Before You Start an SSI Application
Gather these documents first
Before you contact Social Security, collect your birth certificate, proof of citizenship or legal residency, a Social Security card if you have one, and recent pay stubs or tax returns showing your income. You will also need bank statements from the last two months and a list of any assets you own — a house, car, savings account, or anything else of value. Social Security needs these to confirm you meet the income and resource limits.
If you are applying because of a medical condition, bring medical records from your doctors, hospital visits, or mental health providers. These do not have to be official copies yet — you can bring what you have, and Social Security will request the official versions directly from your providers. Bring a list of all medications you take and the names and phone numbers of the doctors or clinics treating you.
If you are applying for a child, you will need the child's birth certificate and Social Security card, plus proof of the parent's or guardian's income and resources. If the child receives treatment from a school or clinic, bring those contact details too.
Key Takeaways
- Bring your birth certificate, proof of citizenship or legal residency, recent pay stubs or tax returns, and bank statements from the last two months to your first appointment.
- Medical records, medication lists, and doctor contact information speed up the process, though Social Security can request these directly from providers if you do not have copies.
- You can start the process online at ssa.gov, by phone at 1-800-772-1213, or in person at your local Social Security office — all three routes lead to the same application.
- The application itself takes 20 to 40 minutes, but the full decision process usually takes three to six months, or longer if Social Security needs more medical evidence.
- If you are denied, you can file a reconsideration request within 60 days, and most people who appeal eventually receive benefits.
Where to start the application
You have three ways to begin: online at ssa.gov, by calling 1-800-772-1213 (TTY 1-800-325-0778), or by walking into your local Social Security office. The online route is fastest if you have a computer and internet access — you can fill out the form at your own pace and submit it immediately. The phone line has wait times that vary by time of day and season, but you can schedule a callback instead of holding.
If you go in person, bring the documents listed above and plan to spend 30 minutes to an hour. The office will take your application that day. All three routes produce the same result: your application goes into the system, and a caseworker is assigned to your file.
If you are over 65, you may be applying for Supplemental Security Income (SSI) or for retirement benefits instead — Social Security will help you figure out which one you may have access to for during the application. If you are under 65 and have worked, you might may have access to for both SSI and retirement benefits, and Social Security will sort that out too.
What happens after you submit
Social Security sends you a notice within two weeks confirming they received your application and listing what documents they still need from you. If you did not bring medical records, they will request them from your doctors. If you did not provide proof of citizenship, they will ask for that. Read this notice carefully and respond within the deadline — usually 10 days — or your application may be delayed.
A caseworker then reviews your medical evidence and your income and resources. This takes two to six months on average, though cases involving complex medical conditions or missing records can take longer. You do not have to do anything during this time unless Social Security contacts you asking for more information.
Social Security will mail you a decision letter. If you are approved, the letter says when your first payment arrives and how much it will be. If you are denied, the letter explains why and tells you how to file a reconsideration request.
Income and resource limits you need to know
SSI has strict income limits. In 2024, the monthly income limit is $943 for an individual and $1,415 for a couple, though these amounts change each year. Income includes wages, self-employment earnings, unemployment benefits, and some other sources. Social Security counts some income differently — for example, the first $65 of monthly wages does not count, and neither does the first $20 of other income.
You can own no more than $2,000 in resources if you are single, or $3,000 if you are married. Resources include cash, bank accounts, stocks, and bonds. Your house and one car do not count toward this limit, and neither do household goods or personal items. If you own more than the limit, you will not may have access to for SSI, though you may may have access to for other programs.
If your income or resources are close to the limit, bring documentation showing exactly what you have. Social Security sometimes counts things differently than you expect, and having clear records helps them make the right decision faster.
If you are denied the first time
About 65 to 70 percent of first-time applications are denied. This does not mean you will never receive benefits — it means Social Security did not find enough medical evidence that your condition prevents you from working, or that your income or resources were too high. The denial letter explains which reason applies to you.
You have 60 days from the date on the denial letter to file a reconsideration request. This sends your case to a different caseworker who reviews it from scratch. You can submit new medical records, new test results, or a statement from your doctor explaining why your condition is disabling. Many people who are denied on the first try are approved on reconsideration, especially if they provide stronger medical evidence the second time.
If you are denied again, you can request a hearing before an administrative law judge. This is a more formal process where you can present evidence and answer questions, but you do not have to go to court. Many people win at the hearing stage.
What to do while you wait for a decision
Keep working with your doctors and follow their treatment plans. Social Security looks at whether you are receiving ongoing medical care and following medical advice. If you stop going to appointments or stop taking prescribed medication, it can hurt your case.
Keep records of your medical visits, test results, and any new symptoms or changes in your condition. Write down dates and what happened. If you see a new doctor or specialist, give them a copy of your previous medical records so they have the full picture.
Do not spend down your resources to get below the limit — Social Security can see transfers of money and may count them as resources anyway. If you have questions about whether something counts as income or resources, call Social Security and ask before you make a decision.

Frequently Asked Questions
Can I start an SSI application online if I do not have a computer?
Yes. Call 1-800-772-1213 to start by phone, or go to your local Social Security office in person. Both routes work just as well as the online application. If you need help filling out the form, a Social Security representative can walk you through it over the phone or at the office.
What if I do not have a birth certificate?
Contact the vital records office in the state where you were born and request a copy. This usually costs $10 to $30 and takes one to three weeks. While you wait, you can start your SSI application — Social Security can work with other forms of ID temporarily and will follow up if they need the birth certificate.
Do I need a lawyer to apply for SSI?
No. You can apply on your own at no cost. Many people are approved without a lawyer. If you are denied and file a reconsideration or hearing request, a lawyer can help, but you do not need one to start. If you do hire a lawyer later, they can only charge you if you win, and Social Security caps the fee at 25 percent of your back pay.
How much back pay will I receive if I am approved?
SSI does not pay back to the date you applied — it pays back only one month, to the first day of the month you applied. This is different from other Social Security benefits. Your first payment includes that one month of back pay plus the current month.
What if my income changes while I am waiting for a decision?
Tell Social Security right away. Call your caseworker or the main line at 1-800-772-1213. Changes in income can affect whether you may have access to or how much you receive, so reporting them quickly prevents overpayments or delays in your case.
