If you're living with a serious health condition that prevents you from working, Social Security Disability Insurance (SSDI) can be a financial lifeline. For California residents, understanding how the program works and what it takes to qualify can make the difference between getting the help you need and facing unnecessary delays or denials.
This guide walks you through the key eligibility requirements, how the application process works, and what steps you can take to strengthen your claim.
What Is SSDI and Who Is It For?
SSDI is a federal program administered by the Social Security Administration (SSA). It provides monthly benefits to people who have a qualifying disability and have worked long enough to earn sufficient work credits through Social Security taxes.
Unlike Supplemental Security Income (SSI), which is based on financial need, SSDI is tied to your work history. That means your past earnings and tax contributions play a significant role in determining whether you're eligible.
The Two Main Eligibility Requirements
To qualify for SSDI in California, applicants must meet two core eligibility requirements set by the Social Security Administration. These requirements focus on your work history and the severity of your medical condition. Understanding both is essential before applying or filing an appeal.
1. You Must Have a Qualifying Disability
The SSA defines a disability as a physical or mental condition that prevents you from performing substantial gainful activity (SGA) and is expected to last at least 12 months or result in death. This is a strict definition — partial or short-term disabilities generally do not qualify.
Common qualifying conditions include, but are not limited to: chronic heart disease, cancer, severe mental health disorders, musculoskeletal problems such as back injuries, neurological conditions like multiple sclerosis or epilepsy, and autoimmune diseases.
The SSA uses a five-step evaluation process to determine whether your condition qualifies. They look at whether you're currently working, the severity of your condition, whether your condition matches their official list of impairments, your ability to do past work, and your ability to do any other type of work.
2. You Must Have Enough Work Credits
Work credits are earned through your employment history. In 2024, you earn one credit for every $1,730 in covered earnings, up to a maximum of four credits per year. Most people need 40 credits total — with 20 of those earned in the last 10 years before the disability began.
Younger workers may qualify with fewer credits. If you became disabled in your late 20s or early 30s, the SSA applies a different credit scale that takes your age into account.
California-Specific Considerations
While SSDI is a federal program, California residents should be aware of a few state-level factors that can affect your benefits and overall financial situation.
California does not tax SSDI benefits at the state level, which means you keep more of what you receive. Additionally, California has its own State Disability Insurance (SDI) program, which provides short-term benefits for workers who can't work temporarily. SDI and SSDI are separate programs — SDI is not a path to SSDI, but some applicants use SDI while their long-term SSDI claim is being processed.
California also has its own Medi-Cal program. If you're approved for SSDI, you'll typically become eligible for Medicare after a 24-month waiting period. In the meantime, Medi-Cal may help cover your healthcare costs.
How to Apply for SSDI in California
You can apply for SSDI in three ways: online at ssa.gov, by phone at 1-800-772-1213, or in person at the Social Security office in California. California has numerous SSA field offices across the state, from Los Angeles and San Francisco to Sacramento and San Diego.
When you apply, be prepared to provide:
- Your Social Security number and proof of age
- Medical records, doctor's notes, and test results related to your condition
- A list of all medications you're currently taking
- Your work history for the past 15 years
- Your most recent W-2 forms or federal tax returns if self-employed
- Bank account information for direct deposit
What Happens After You Apply in California?
After you submit your application, the SSA will review it and then send it to your state's Disability Determination Services (DDS) office. In California, the DDS evaluates the medical aspects of your claim. This process typically takes three to six months, though it can take longer depending on the complexity of your case and how quickly medical records are obtained.
It's important to note that most initial SSDI applications are denied. If yours is denied, you have the right to appeal. The appeals process has four levels: reconsideration, a hearing before an Administrative Law Judge (ALJ), review by the Appeals Council, and finally federal court review. Many successful claims are approved at the ALJ hearing stage, so don't give up after an initial denial.
Tips for Strengthening Your SSDI Claim
Building a strong claim from the start can improve your chances of approval and reduce the time you spend waiting. A few practical steps can make a significant difference.
Keep consistent and detailed medical records. Regular visits to your doctor create a documented history of your condition. Gaps in treatment can raise questions about the severity of your disability. Make sure your doctors understand how your condition limits your ability to work — a physician's statement that explains your functional limitations in specific terms is far more helpful than one that simply lists your diagnosis.
Be thorough and honest on your application. Describe how your disability affects your daily life — not just at your worst moments, but on a typical day. The SSA evaluates your ability to perform consistent, full-time work, so it helps to paint an accurate picture of your limitations.
Many Social Security disability attorneys work on a contingency basis, meaning they only get paid if you win your case. Having experienced legal representation — especially at the appeal stage — can significantly increase your chances of success
