How to file for SSI
You file for Supplemental Security Income (SSI) by contacting Social Security directly — either online through their website, by phone, or in person at your local Social Security office. The online route is fastest: you can start an application on ssa.gov without waiting for an appointment. By phone, call 1-800-772-1213 (TTY 1-800-325-0778). In person, walk into any Social Security office with your documents ready.
The process takes weeks or months, not days. Social Security will ask for proof of your age, citizenship or legal residency, income, resources, and medical condition. You'll need to be thorough and honest — incomplete applications get denied and sent back. Once you file, Social Security assigns you a case worker who will contact you with questions.
SSI is different from Social Security Disability Insurance (SSDI). SSI is need-based, meaning your income and assets matter. SSDI is based on work history. You may be able to file for both at the same time, and Social Security will evaluate you for each program.
Key Takeaways
- You can start an SSI application online at ssa.gov, by calling 1-800-772-1213, or at your local Social Security office — online is usually fastest.
- Gather documents before you file: birth certificate, proof of citizenship or legal residency, recent pay stubs or tax returns, bank statements, and medical records related to your condition.
- SSI decisions can take two to four months, and most initial claims are denied — you have the right to request reconsideration or a hearing if yours is.
- Your income and assets affect whether you get SSI and how much you receive, so be prepared to report everything Social Security asks about.
- If you are under 18, a parent or guardian must file on your behalf, but you can authorize someone to represent you at any age.
Documents you need before you start
Gather these documents before you contact Social Security. Having them ready speeds up the process and reduces the chance your application gets delayed or denied for missing information.
Proof of age: Your birth certificate is the standard. If you don't have one, Social Security will tell you how to get a certified copy from your state's vital records office. A passport or driver's license also works.
Proof of citizenship or legal residency: U.S. citizens need a birth certificate, passport, or naturalization papers. If you are not a citizen, you need your green card, work permit, or other immigration documents showing you are lawfully in the country. Social Security can verify some of this electronically, but bring originals or certified copies.
Income records: Bring recent pay stubs (last two months), tax returns (last two years), and any letters showing benefits you receive — unemployment, workers' compensation, pension, child support. If you are self-employed, bring profit-and-loss statements or business tax returns.
Bank and asset statements: SSI has strict limits on how much you can own. Bring recent statements (within the last month) for all checking and savings accounts, investment accounts, and anything else of value. Social Security needs to see the account balance and your name on the account.
Medical records: Bring records from doctors, hospitals, therapists, or specialists who have treated your condition. Include dates of visits, diagnoses, test results, and current medications. If you don't have copies, ask your provider's office for them — this can take weeks, so start early.
Filing online through ssa.gov
The online application is called iClaim and is available at ssa.gov/applyforbenefits. You do not need to log in or create an account to start. The form asks for your personal information, work history, income, assets, living situation, and medical condition. You can save your progress and come back later if you need to gather more information.
The online form takes 15 to 30 minutes if you have your documents ready. At the end, you will see a confirmation number. Write it down or print the page. Social Security will contact you within a few days to schedule an appointment to verify your information and sign the official application.
Online filing does not mean you avoid talking to Social Security. You will still need to meet with someone (by phone or in person) to complete the process. But starting online means you skip the waiting room and get a faster appointment.
Filing by phone or in person
If you call 1-800-772-1213, a Social Security representative will walk you through the application over the phone. Have your documents nearby. The call usually takes 30 to 45 minutes. At the end, Social Security will schedule you for an in-person appointment to sign the official application and provide original documents.
If you go in person to your local Social Security office, bring all your documents and arrive early. Offices are often busy, and wait times vary. You can find your nearest office and check hours at ssa.gov/locator. Some offices let you make an appointment online; others work on a first-come, first-served basis. Call ahead to ask.
Whether you file by phone or in person, you will need to attend a follow-up appointment to sign the official application and provide proof of your information. Social Security will not process your claim until you do this.
What happens after you file
After you submit your application, Social Security sends you a notice with your claim number and the date you filed. Keep this notice. Your case worker may contact you by phone or mail to ask follow-up questions or request more documents. Respond quickly — delays in providing information can slow your case.
Social Security will also contact your doctors and employers to verify information you provided. This takes time, especially if your medical providers are slow to respond. You can speed this up by giving Social Security the contact information for your current doctors and asking them directly to send records.
A decision usually comes within two to four months, though some cases take longer. You will receive a written notice in the mail explaining whether you were approved or denied. If you are denied, the notice will explain why and tell you how to request reconsideration or a hearing.
If you are denied
Most people are denied on their first application. This does not mean you are ineligible — it often means Social Security needs more medical evidence or your case is borderline. You have the right to request reconsideration, which means Social Security will review your case again with new or additional information.
You must request reconsideration within 60 days of the denial notice. You can do this online, by phone, or in person. If reconsideration is also denied, you can request a hearing before an administrative law judge. A hearing gives you the chance to present your case in more detail, sometimes with a lawyer or representative.
Many people win on reconsideration or at a hearing. If you decide to pursue either, consider working with a representative — a lawyer or non-lawyer advocate who specializes in Social Security cases. They are paid only if you win, and their fee comes from your back pay, not from you upfront.
Using a representative or advocate
You can authorize someone to represent you at any stage of the SSI process. This can be a lawyer, a non-lawyer advocate, a family member, or a friend. You do not need a representative to file, but having one can help if your case is complex or if you are denied and need to appeal.
Representatives who are lawyers or accredited non-lawyers must be certified by Social Security. You can find certified representatives through the National Organization of Social Security Claimants' Representatives (nosscr.org) or by asking your local legal aid office. Many work on contingency, meaning they take a percentage of your back pay if you win — usually 25 percent, capped at a maximum amount set by Social Security.
To authorize a representative, you fill out Form SSA-1696 and give it to Social Security. Your representative can then contact Social Security on your behalf, request records, and represent you at hearings.
Frequently Asked Questions
Can I file for SSI if I am still working?
Yes. SSI is based on your total income, not whether you work. If you earn below the monthly limit (which changes yearly), you can still receive SSI. Social Security counts some work income differently — they allow you to earn a small amount before reducing your benefit. Report all income honestly when you file.
How much money and assets can I have and still get SSI?
SSI has strict resource limits. As of 2024, you can have no more than $2,000 in countable resources if you are single, or $3,000 if you are married. Some things don't count — your home, one car, household goods, and certain other items. Social Security will explain what counts when you file. These limits change yearly, so confirm the current amount when you apply.
What if I don't have a birth certificate?
Contact your state's vital records office (usually part of the health department) and request a certified copy. You will need to provide proof of identity and pay a fee, usually $10 to $30. This can take two to four weeks. While you wait, you can still start your SSI application online or by phone — Social Security will work with you on getting the birth certificate later.
Do I have to go to the Social Security office in person?
You will need to meet with someone from Social Security to sign the official application and verify your identity. This can happen by phone or video call in some cases, especially if you have a disability that makes travel difficult. Ask Social Security about your options when you file.
What if my condition gets worse while I am waiting for a decision?
Report any changes to your case worker immediately. Send updated medical records showing your current condition. Changes in your health can affect the decision, and Social Security needs current information to make an accurate information.
