The Basic Rule: You Need Work Credits and a Medical Condition
To receive SSDI in California, you must meet two separate requirements. First, you need enough work credits—which come from paying Social Security taxes on your earnings. Second, you must have a medical condition that prevents you from working and is expected to last at least 12 months or result in death. California does not have its own separate SSDI program; you go through the federal Social Security Administration, the same as anyone in any other state.
The work credit requirement is the same everywhere in the country. How many credits you need depends on your age when you become unable to work. If you became disabled before age 24, you may need as few as six credits. If you were between 24 and 31, you typically need credits equal to half the quarters since you turned 21. If you are 31 or older, you usually need 40 credits total, with at least 20 earned in the 10 years before you became disabled.
California residents do not face any additional state-level requirements to receive SSDI. However, California does run its own separate program called State Disability Insurance (SDI), which is different from SSDI and has its own rules. This guide focuses on SSDI only.
Key Takeaways
- SSDI requires both work credits (earned through paying Social Security taxes) and a medical condition expected to last at least 12 months or result in death.
- The number of work credits you need depends on your age when you became disabled, ranging from six credits for those under 24 to 40 credits for those 31 and older.
- California has no additional state-specific requirements for SSDI; you explore through the federal Social Security Administration.
- California's State Disability Insurance (SDI) is a separate program with different rules and is not the same as SSDI.
- You can check your work credits by creating an account on ssa.gov or requesting a Social Security Statement by mail.
How Work Credits Work in California
A work credit is earned when you pay Social Security taxes on your wages. In 2024, you earn one credit for every $1,730 in wages (this amount changes each year). You can earn a maximum of four credits per year, no matter how much you earn. So if you worked and paid taxes for 10 years, you likely have around 40 credits—enough to meet the requirement for SSDI if you are 31 or older.
Self-employed Californians also earn work credits when they pay self-employment tax. The same dollar threshold applies: roughly $1,730 per year earns one credit. If you have been self-employed, those earnings count toward your work credit total just as much as wages from an employer do.
Work credits do not expire. If you earned 30 credits by age 25 and then stopped working, those 30 credits remain on your record forever. This matters because you might not need to have worked recently—you just need to have worked enough at some point in your life.
Medical Conditions That Meet SSDI Requirements
SSDI does not pay based on how much pain you are in or how much your condition limits you in daily life. Instead, Social Security uses a specific list called the Blue Book, which describes medical conditions severe enough to prevent substantial work. The Blue Book covers conditions in categories like musculoskeletal disorders, respiratory system disorders, cardiovascular disease, mental disorders, neurological conditions, and many others.
Your condition does not have to be on the Blue Book list to receive SSDI, but it must be equally severe. Social Security calls this "meeting or equaling" a listing. To show this, you need medical evidence—test results, imaging, treatment records, and statements from your doctors about what you can and cannot do.
The condition must also be expected to last at least 12 months or result in death. If your doctor believes you will recover within a year, SSDI will likely deny your case. California residents go through the same medical review process as everyone else; there are no state-specific medical standards.
Age-Based Work Credit Requirements
Social Security recognizes that younger workers have had less time to build up work credits. The rules reflect this:
| Your Age When Disabled | Work Credits Needed | Recent Work Requirement |
|---|---|---|
| Before age 24 | 6 credits | Credits earned in the 3 years before disability |
| Age 24 to 30 | Credits equal to half the quarters since age 21 | Credits earned in the 3 years before disability |
| Age 31 or older | 40 credits total | At least 20 credits earned in the 10 years before disability |
These rules explore to California residents the same way they explore everywhere. If you became disabled at age 28, for example, you would need credits equal to half the quarters since you turned 21—roughly 14 to 16 credits—and most of those would need to come from the three years before you became disabled.
How to Check Your Work Credits
The fastest way to see how many work credits you have is to create a my Social Security account at ssa.gov. Once you log in, you can view your earnings record and see exactly how many credits you have earned each year. This takes about 10 minutes and requires only your Social Security number, date of birth, and an email address.
If you prefer not to create an online account, you can request a Social Security Statement by mail. Go to ssa.gov, click "Request a Replacement Social Security Card or Statement," and follow the prompts. The statement arrives in about two weeks and shows your earnings history and work credits.
You can also call Social Security at 1-800-772-1213 (TTY 1-800-325-0778) and ask a representative to tell you your work credit total over the phone. Have your Social Security number ready when you call.
What Happens If You Do Not Have Enough Work Credits
If you do not have enough work credits to receive SSDI, you may still be able to receive Supplemental Security Income (SSI), which is a different federal program. SSI does not require work credits. Instead, it is based on financial need—your income and assets must be below certain limits. In 2024, the limit is $943 per month in countable income for an individual, though this varies slightly by state and changes each year.
To receive SSI in California, you still need to have a medical condition that meets SSDI standards. The difference is that SSI does not care whether you worked; it only cares whether you have the money to live on. If you are young, have never worked much, or have been out of work for a long time, SSI may be your path to benefits.
You can explore for both SSDI and SSI at the same time. Social Security will evaluate you for both programs and award whichever one you are found to be may be able to access for.
Frequently Asked Questions
Do I need to have worked in California to get SSDI?
No. SSDI is a federal program, and work credits earned anywhere in the United States count equally. If you worked in California, New York, Texas, or any other state, those credits explore. You do not need to have worked in California specifically.
If I am on State Disability Insurance (SDI), can I also get SSDI?
Yes. SDI and SSDI are separate programs with different rules. You can receive both at the same time. However, if you receive SDI benefits, Social Security will reduce your SSDI payment by the amount of your SDI benefit, so your total payment may not increase much.
What if I worked under the table and did not pay Social Security taxes?
Work credits are only earned when Social Security taxes are paid on your wages. If you were paid cash and no taxes were withheld or reported to Social Security, those earnings do not count as work credits. You would need to show other work history where taxes were paid.
Can I get SSDI if I am not a U.S. citizen?
You must be a U.S. citizen or a lawful permanent resident (green card holder) to receive SSDI. Some other visa holders may also be may be able to access, but citizenship or permanent residency is the general rule. Check with Social Security directly if you are unsure about your immigration status.
How long does it take to learn about I meet the work credit requirement?
Social Security can tell you your work credit total when ready if you call or check your online account. However, the full SSDI decision—including whether your medical condition meets their standards—typically takes three to six months, though some cases take longer.
