Where to Start: Social Security Disability Insurance vs. State Disability Insurance
California offers two separate disability programs, and which one you use depends on your work history. Social Security Disability Insurance (SSDI) is federal and requires you to have paid Social Security taxes through work. State Disability Insurance (SDI) is California-only and covers workers who have earned recent wages in the state, even if they do not have enough work credits for SSDI. Most people are covered by one or both.
If you worked in California in the past 12 to 18 months and paid into the state disability fund through payroll deductions, you may be covered by SDI. If you worked long enough and recently enough to have Social Security credits, you can file for SSDI. You can file for both at the same time—they do not conflict, and approval for one does not affect the other.
The key difference: SDI pays faster (usually within two to four weeks if you are approved) but the monthly amount is lower. SSDI takes longer to process (three to six months on average) but the monthly payment is usually higher. If you are denied SDI, you can still pursue SSDI. If you are denied SSDI, you can still pursue SDI.
Key Takeaways
- California has two separate programs: SDI (state, faster, lower payment) and SSDI (federal, slower, higher payment), and you can file for both at the same time.
- To file for SDI, contact the California Department of Insurance online or by phone; to file for SSDI, contact Social Security directly or visit your local Social Security office.
- You will need medical records, work history, and proof of income; SDI requires recent California wages, SSDI requires enough work credits from your lifetime earnings.
- SDI decisions usually come within two to four weeks; SSDI decisions usually take three to six months, and most first-time applications are denied.
- If you are denied, you can request reconsideration for either program within 60 days of the denial letter.
Filing for California State Disability Insurance (SDI)
To file for SDI, go to the California Department of Insurance website at www.dir.ca.gov/dib or call 1-877-638-4992. You can file online, by phone, or by mail. Online filing is fastest—you can complete the process in one session and receive a confirmation number when ready.
You will need to provide your Social Security number, driver's license or ID number, the date your disability began, and a description of why you cannot work. You will also need to list your employer(s) from the past 12 to 18 months and your gross wages. Have your recent pay stubs or tax return handy.
After you file, the state will send you a form to have your doctor complete. This form asks about your medical condition, what you can and cannot do, and whether your condition prevents you from working. Your doctor must return it within 20 days. If your doctor does not return it, your claim may be delayed or denied, so follow up with your doctor's office after one week.
SDI pays a percentage of your average weekly wage—usually between 50 and 66 percent—up to a maximum amount that changes each year. Payments begin after a seven-day waiting period from the date your disability started. If you are approved, you will receive your first check within two to four weeks of approval.
Filing for Social Security Disability Insurance (SSDI)
To file for SSDI, visit your local Social Security office, call 1-800-772-1213, or go to www.ssa.gov and create an account to file online. Filing online through your Social Security account is the fastest method and you can save your progress and return later.
You will need your Social Security number, birth certificate, proof of citizenship or legal residency, and a complete work history going back 15 years. Bring W-2 forms or tax returns if you have them. You will also need to list all medical providers who have treated you for your condition, including their names, addresses, and phone numbers.
Social Security will request your medical records directly from your doctors and hospitals. You do not need to gather them yourself, but the process takes time. If you have records already (imaging, test results, specialist letters), you can bring copies to speed things up. Social Security will use these records to decide whether your condition meets their definition of disability.
SSDI requires you to have earned enough work credits based on your age and work history. Most people need 40 credits total, with at least 20 earned in the 10 years before you became disabled. If you are younger, you may need fewer credits. Social Security will tell you during your filing whether you have enough.

The Medical Review Process and What to Expect
Both SDI and SSDI will examine your medical records to decide whether your condition prevents you from working. For SDI, the state sends your doctor a form to complete. For SSDI, Social Security requests records from all your doctors and may send you to a doctor they choose for an examination (at no cost to you).
The medical review takes time. SDI usually completes it within two to four weeks. SSDI usually takes three to six months because they review more thoroughly and may order additional tests or evaluations. During this time, you will not hear much—no news does not mean your claim is denied.
If Social Security schedules you for a consultative examination (CE), you will receive a letter with the date, time, and location. Attend this appointment. If you miss it without calling ahead to reschedule, your claim may be denied. The doctor at the CE will ask about your symptoms, your daily activities, and what you can and cannot do physically or mentally.
After the medical review, you will receive a decision letter. If you are approved, the letter will state your monthly payment amount and when payments begin. If you are denied, the letter will explain why and tell you how to request reconsideration.
Timeline and Payment Start Dates
SDI moves faster than SSDI because the state only needs to confirm your recent work history and current medical condition. Most SDI decisions come within two to four weeks of filing. If approved, your first payment arrives within one to two weeks of approval, minus the seven-day waiting period from your disability start date.
SSDI takes longer because Social Security must verify your entire work history and confirm you have enough credits. The average time from filing to a decision is three to six months, though some cases take longer if additional medical evidence is needed. If you are approved, your first payment comes the month after approval is granted.
Both programs have a waiting period before payments begin. SDI has a seven-day waiting period from the date your disability started. SSDI has a five-month waiting period from the date your disability began (you do not receive payment for those first five months, even if approved). This means if you file for SSDI and are approved, your first check covers the sixth month of disability onward.
What Happens If You Are Denied
Most first-time SSDI applications are denied. This does not mean you are ineligible—it means Social Security needs more information or believes the medical evidence does not yet show you cannot work. SDI denials are less common but do happen.
If you are denied, you have 60 days from the denial letter to request reconsideration. This means a different reviewer will look at your case. You can submit new medical evidence, updated doctor's statements, or additional work history. Many people are approved on reconsideration.
To request reconsideration for SDI, contact the California Department of Insurance at the same number you used to file. To request reconsideration for SSDI, contact Social Security or visit your local office. The reconsideration process takes another two to three months for SDI and three to six months for SSDI.
If you are denied again after reconsideration, you can request a hearing before an administrative law judge. This is a formal process where you can present evidence and testimony. Many people win at the hearing stage, especially if they have new medical evidence or a lawyer representing them.
Frequently Asked Questions
Can I file for both SDI and SSDI at the same time?
Yes. They are separate programs with different rules, and approval for one does not affect the other. Filing for both gives you two chances to receive benefits and increases the likelihood that at least one will approve you. There is no penalty for filing for both.
What if I do not have recent pay stubs for SDI?
Contact your employer's payroll or human resources department and ask them to provide a wage statement or letter showing your earnings for the past 12 to 18 months. You can also use your tax return (Form 1040) or W-2 forms. If you are self-employed, bring your business tax returns.
Do I need a lawyer to file for disability?
No, you can file on your own. However, a lawyer or non-lawyer representative can help you gather medical evidence, prepare your case, and represent you at a hearing if you are denied. They are paid only if you win, and their fee is capped by law at 25 percent of your back pay (the money owed from when you became disabled).
What if my condition improves while I am waiting for a decision?
Tell the program when ready. If your condition improves enough that you can work, your claim may be denied or closed. If it improves only partially, you may still be approved. Being honest about changes in your condition is important—programs verify this through medical records and may schedule follow-up exams.
How much will I receive if I am approved?
SDI pays 50 to 66 percent of your average weekly wage, up to a maximum that changes yearly (in 2024, the maximum is around $1,450 per week, but this varies). SSDI payment depends on your lifetime earnings record and is calculated by Social Security. You can estimate your SSDI payment by creating an account at ssa.gov and viewing your earnings record.
