Where to File and What You'll Need

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. There is no separate California disability program that replaces the federal one. 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.

Before you contact Social Security, gather these documents: your Social Security card, birth certificate, proof of citizenship or legal residency, W-2 forms or tax returns from the past year, and a list of all doctors and hospitals that have treated you. If you have medical records at home, bring those too—Social Security will request them from your providers, but having them ready speeds things up. You will also need to list all medications you take and describe how your condition affects your ability to work.

California residents can find their nearest Social Security office by visiting ssa.gov/locator or calling 1-800-772-1213. Many offices now require an appointment rather than walk-in service, so call ahead. If you cannot leave home due to your disability, you can request a phone interview or, in some cases, a home visit.

Key Takeaways

  • You file with the Social Security Administration (federal), not California state government, either online at ssa.gov, by phone at 1-800-772-1213, or at your local Social Security office.
  • Have your Social Security card, birth certificate, proof of residency, recent tax returns, and a complete list of all doctors and hospitals ready before you contact Social Security.
  • California's Disability information Services (DDS) will review your medical evidence and make the initial decision, which typically takes three to five months.
  • If Social Security denies your claim, you have 60 days to file a written appeal; most people who appeal with a lawyer or representative win on the second or third try.

The Role of California's Disability information Services

After you file, your case goes to California's Disability information Services (DDS), a state agency that contracts with Social Security to review medical evidence and make the initial decision on your claim. DDS is not a separate program—it is part of the federal SSDI and SSI process. The DDS office in your region will request medical records from your doctors, may order a consultative exam if your records are incomplete, and then writes a decision letter.

The DDS review typically takes three to five months, though it can take longer if your medical records are scattered across multiple providers or if you need additional testing. You do not need to do anything during this waiting period except respond promptly if DDS contacts you asking for more information. If you move during the process, notify Social Security when ready so your file does not get lost.

DDS will send you a decision letter in the mail. If approved, the letter will state your monthly benefit amount and when payments begin. If denied, the letter will explain the reason and tell you how to appeal.

Understanding SSDI vs. SSI in California

SSDI is based on your work history. You must have worked and paid Social Security taxes for a certain number of quarters (typically 20 of the last 40 quarters if you are under 31). There is no income or asset limit for SSDI, and you can have savings, a home, or a car without affecting your benefits. SSDI also gives you access to Medicare after two years of receiving benefits.

SSI is a needs-based program for people with low income and few assets. To receive SSI in California, your monthly income must be below a certain threshold (which changes yearly) and your countable resources must not exceed $2,000 for an individual or $3,000 for a couple. SSI recipients in California also receive Medi-Cal (the state Medicaid program) automatically. SSI payments are typically lower than SSDI payments.

You can receive both SSDI and SSI at the same time if your SSDI benefit is very small. When you file, Social Security will determine which program you are may have access to to based on your work history and current income and assets. If you are unsure which applies to you, Social Security staff can explain your situation during your initial interview.

What Happens After You File

Once you submit your process, Social Security sends you a notice confirming receipt. Keep this notice. You will receive updates by mail as your case moves through DDS review. If Social Security needs additional information—such as medical records from a provider you forgot to list, or clarification about your work history—they will contact you by mail or phone.

During the review, you may be asked to attend a consultative exam (CE), which is a medical appointment paid for by Social Security. This is not a test you can pass or fail; it is straightforward a way for Social Security to gather current medical evidence if your records are old or incomplete. The exam is usually with a doctor or psychologist you have never seen before. Bring a list of your medications and a written description of how your condition affects you daily.

If you are working while your case is pending, report your earnings to Social Security. For SSDI, you have a trial work period that allows you to earn money without losing benefits, but you must report it. For SSI, any earnings reduce your benefit dollar-for-dollar after a small monthly exclusion, so reporting is critical to avoid overpayment.

What to Do If Your Claim Is Denied

Social Security denies roughly 65 to 70 percent of initial SSDI and SSI claims. A denial does not mean you are ineligible—it usually means Social Security believes your medical condition does not meet their definition of disability, or your work history does not may have access to you for SSDI. You have the right to appeal.

You have 60 days from the date on your denial letter to file a written appeal. The appeal process has four stages: reconsideration (a different DDS examiner reviews your file), a hearing before an Administrative Law Judge (ALJ), Appeals Council review, and federal court. Most people who hire a lawyer or representative win at the hearing stage (stage three). Many lawyers work on contingency, meaning they take a percentage of your back pay (usually 25 percent, capped at $7,200) only if you win.

To appeal, write a letter to Social Security saying you disagree with the decision and want to appeal. Include your claim number (on your denial letter) and mail it to the address on the denial letter. Social Security will send you a form to complete and explain what happens next. Do not delay—the 60-day window is strict.

California-Specific Resources and Programs

While SSDI and SSI are federal programs, California offers additional support that may help while you wait for a decision or after you are approved. The California Department of Rehabilitation (DOR) offers vocational rehabilitation services—job training, assistive technology, and work support—at no cost to people with disabilities. You can contact DOR through your local office or at dor.ca.gov.

If you are approved for SSI, you automatically receive Medi-Cal in California. If you are approved for SSDI, you become may be able to access for Medicare after a two-year waiting period. During those two years, you may be able to enroll in Medi-Cal if your income is low enough. Contact your county social services office or visit dhcs.ca.gov to learn about Medi-Cal.

The California Protection and Advocacy (P&A) agency can help you understand your rights and navigate the disability system at no cost. You can reach them at 1-800-776-5746 or visit disabilityrightsca.org. They do not represent you in appeals, but they can answer questions about the process and connect you to legal resources.

Timeline and What to Expect

The entire initial process—from filing to receiving a decision—usually takes three to five months. Some cases move faster if your medical evidence is clear and recent; others take longer if records are hard to obtain or if your condition requires additional evaluation. There is no way to speed up the DDS review, but you can help by providing complete and accurate information when you file and by responding quickly to any requests for more information.

If you are denied and appeal, expect the reconsideration stage to take another two to three months. If you request a hearing before an ALJ, the wait is typically six to eighteen months depending on your local hearing office's backlog. During this entire time, you can continue to work and earn money (subject to trial work period rules for SSDI or income limits for SSI).

If you are approved, your first payment arrives the month after you are approved. For SSDI, you receive back pay going back to the date you filed (or the date your disability began, if later). For SSI, back pay is limited to one year before the month you filed. This back pay is paid in a lump sum or in installments depending on the amount.

Frequently Asked Questions

Can I file for disability online in California?

Yes. Go to ssa.gov/applyfordisability and complete the online process. You can also call 1-800-772-1213 or visit your local Social Security office in person. Online filing is often fastest because you can do it at your own pace and Social Security receives it when ready.

Do I need a lawyer to file for disability?

No. You can file on your own. However, if your claim is denied and you appeal to a hearing, having a lawyer or representative significantly increases your chances of winning. Many representatives work on contingency and charge only if you win.

What if I am still working when I file?

You can file while working. For SSDI, you have a trial work period that lets you earn up to a certain amount monthly without losing benefits. For SSI, earnings reduce your benefit, so report all work income to Social Security. Continuing to work does not hurt your claim.

How much will I receive in monthly benefits?

SSDI amounts depend on your work history and earnings record; the average is around $1,500 monthly, but it varies widely. SSI in California provides a maximum of around $943 monthly for an individual (amounts change yearly). Social Security will tell you your estimated benefit amount during your initial interview.

What if I disagree with the DDS decision?

You have 60 days from the date on your decision letter to file a written appeal. Mail a letter stating you disagree and want to appeal to the address on your denial letter, including your claim number. Social Security will send you forms and explain the next steps in the appeal process.
