Where to File and What Form to Use

You file for Social Security Disability Insurance (SSDI) or Supplemental Security Income (SSI) with the federal Social Security Administration, not with the state of California. Both programs are federal, though California has its own rules about how much money and property you can have and still receive SSI.

You have three ways to file: online at ssa.gov, by phone at 1-800-772-1213 (TTY 1-800-325-0778), or in person at your local Social Security office. The online method is fastest — you can complete the process in one sitting and submit it when ready. By phone, a representative will walk you through the questions, which takes 15 to 20 minutes. In person, you bring documents with you and file on the spot.

The form you use depends on which program you are filing for. For SSDI (based on your own work history or a parent's), you file Form SSA-16. For SSI (based on financial need, not work history), you file Form SSA-8000. If you are not sure which one you may have access to for, the Social Security representative on the phone or at your local office can tell you before you file.

Key Takeaways

  • File with the Social Security Administration, not California — you can start online at ssa.gov, by phone at 1-800-772-1213, or at your local Social Security office.
  • Gather your birth certificate, proof of citizenship or legal residency, tax returns or pay stubs, and medical records before you file, because you will need to reference them during the process.
  • The process itself takes 15 to 30 minutes, but the full review process takes three to six months on average, and many people are denied on the first decision.
  • If you are denied, you have 60 days to file a reconsideration request, which is your first appeal step and does not cost money.
  • California residents can contact Disability Rights California for free help understanding the process or preparing your case.

Documents You Need Before You Start

Have these documents ready or nearby when you file, whether online or by phone. You do not have to upload or mail them with the process itself, but Social Security will ask you questions about them, and you will need to send them later.

Start with proof of who you are: your birth certificate (original or certified copy) and a photo ID such as a driver's license or passport. If you were born outside the United States, bring your passport and proof of legal residency — a green card, visa, or I-94 arrival record. If you are a U.S. citizen born abroad, bring your Certificate of Naturalization or Certificate of U.S. Citizenship.

Next, gather financial records. Bring your most recent tax return (Form 1040) and pay stubs from the last month or two. If you are self-employed, bring your tax return for the last two years and a profit-and-loss statement for the current year. If you have not worked recently, bring a letter from your employer stating when you stopped working and why, if possible.

Finally, collect medical evidence. This is the most important part of your case. Bring a list of all doctors, therapists, hospitals, and clinics you have seen in the past three years, along with the dates of your visits. Bring copies of recent test results, imaging reports, hospital discharge summaries, and mental health treatment records. If you have not seen a doctor in a while, schedule an appointment before you file — Social Security needs current medical evidence, not just old records.

The Online process Process, Step by Step

Go to ssa.gov and look for the "explore for Disability" button on the homepage. You will be taken to a find portal where you create an account using your email address and a password. Save this password — you will use it to check the status of your case later.

The process has six sections. In the first, you enter your name, date of birth, Social Security number, and contact information. In the second, you describe your work history — every job you have held in the past 15 years, including the dates you worked, what you did, and how much you earned. Be as specific as possible; vague descriptions slow down the review.

The third section asks about your medical condition. You will list every condition that prevents you from working, describe when it started, and name the doctors treating it. The fourth section asks about your daily activities — can you cook, clean, shop, manage money, or care for yourself? Answer honestly. If your condition makes these tasks hard or impossible, say so.

The fifth section asks whether you have filed for disability before. If you have, provide the date and the decision you received. The sixth section is a declaration where you confirm that the information you provided is true. You sign it electronically and submit the process. You will receive a confirmation number when ready.

What Happens After You File

Social Security sends your process to a state agency called Disability information Services (DDS). In California, this is part of the Department of Social Services. DDS has your process reviewed by a disability examiner and a medical consultant who have never met you.

They will request your medical records directly from your doctors and hospitals — you do not have to send them. This process takes two to four weeks. Once they have your records, they review them against the Social Security "Blue Book," which lists conditions that automatically may have access to for disability. If your condition is not on the list, they assess whether your condition is severe enough to prevent you from doing any work.

The entire review takes three to six months on average. You can check the status of your case online using your ssa.gov account, or by calling 1-800-772-1213. Social Security will mail you a decision letter when the review is complete. The letter will say you are approved, denied, or approved for a different program than you applied for (for example, approved for SSI instead of SSDI).

If You Are Denied: Your Appeal Rights

About 65 to 70 percent of first-time applicants are denied. This does not mean you cannot receive benefits — it means you have the right to appeal the decision at no cost.

You have 60 days from the date on your decision letter to file an appeal. The first appeal step is called reconsideration. You submit a new request to Social Security saying you disagree with the decision and want it reviewed again. You can do this online, by phone, or in person. Include any new medical evidence you have gathered since your first process — new test results, a letter from your doctor, or records from a recent hospitalization all strengthen your case.

Reconsideration takes another three to six months. If you are denied again, you can request a hearing before an Administrative Law Judge (ALJ). This is a more formal process where you can present evidence and testify about your condition. You can bring a representative — a lawyer, a non-lawyer advocate, or a family member — to speak on your behalf. Many people are approved at the hearing stage, especially if they have strong medical evidence and a representative.

If you are denied after the hearing, you can appeal to the Appeals Council, and then to federal court. Each step takes several months. Throughout the entire process, you can work with a disability representative at no upfront cost — they are paid only if you win, and only from your back pay.

Getting Help in California

Disability Rights California is a free legal advocacy organization that helps people understand the disability process and prepare their cases. You can reach them at 1-800-776-5746 or through their website at disabilityrightsca.org. They do not file applications for you, but they can review your case, help you gather evidence, and represent you at a hearing.

Your local Social Security office can also answer questions about the process process. Find the office nearest you at ssa.gov/locator. Call ahead to ask if they have a wait time — some offices are very busy, and you may be able to schedule an appointment instead of walking in.

If you are low-income and need a lawyer to represent you at a hearing, contact your local legal aid office. California has several regional legal aid organizations that take disability cases for free if you meet their income limits. Search for "legal aid" plus your county name to find the office serving your area.

Frequently Asked Questions

Can I work while my disability case is being reviewed?

Yes. Working does not disqualify you from SSDI or SSI, but your earnings may affect your SSI payment amount. For SSDI, you can earn up to $1,550 per month (in 2024) without it affecting your benefits. If you earn more, Social Security will review whether you are still disabled. Report all work to Social Security — they will find out anyway through tax records.

What if I do not have medical records from the past few years?

Contact your doctors and ask them to send records to Social Security. If you have not seen a doctor recently, schedule an appointment before or shortly after you file. Social Security can work with recent records, but the longer the gap in treatment, the harder it is to prove your condition is disabling. If cost is a barrier, look for community health centers or free clinics in your area.

Do I need a lawyer to file for disability?

No. You can file on your own and many people do. A lawyer or representative is most useful if you are denied and need to appeal, especially if you are preparing for a hearing. At that stage, having someone who knows the process can significantly improve your chances of approval.

How much back pay will I receive if I am approved?

Back pay is the money Social Security owes you from the date you became disabled, not from the date you filed. The exact amount depends on when your disability began and what program you are approved for. Social Security will calculate this in your approval letter. If you have a representative, they will receive up to 25 percent of your back pay as their fee.

What is the difference between SSDI and SSI in California?

SSDI is based on your work history or a parent's work history. SSI is based on financial need — you must have limited income and resources. California adds extra money to SSI payments, so SSI recipients in California receive more than in other states. You may be approved for one, both, or neither depending on your work history and finances.
