What form you actually need to submit for California SDI

The form you file depends on whether you are explore for the first time or you already receive SDI benefits. If you have never filed for State Disability Insurance, you submit Form DI 1 (process for Disability Insurance Benefits) to the California Department of Industrial Relations. If you are already receiving SDI and need to report a change — like returning to work part-time or a change in your medical condition — you use Form DI 3 (Report of Change in Condition) instead.

You can file Form DI 1 online through the SDI website, by mail, or in person at a local Employment Development Department (EDD) office. The online route is fastest: you can upload documents and track your case from your computer. If you mail it, send it to the address listed on the form itself, which varies by region.

Your doctor does not file anything on your behalf. You collect the medical evidence yourself — test results, visit notes, imaging reports — and include it with your form. The SDI office will also request records directly from your healthcare providers once they receive your process.

Key Takeaways

  • Form DI 1 is the process you file when you first explore for SDI; Form DI 3 is what you file if you are already receiving benefits and something has changed.
  • You can file online, by mail, or in person, and online filing is the fastest way to submit documents and track your case.
  • You gather your own medical records and attach them to the form; SDI will also request records from your doctors.
  • The form asks about your work history, the date your disability began, and what prevents you from working.

What information the form asks for

Form DI 1 requests basic personal information: your name, Social Security number, date of birth, and contact details. It also asks when your disability began and what date you stopped working or reduced your hours. You will need to list your employer at the time you became unable to work, including the company name and the dates you worked there.

The form includes a section where you describe your medical condition and what it prevents you from doing. This does not need to be lengthy — a few sentences explaining why you cannot perform your usual job duties is sufficient. For example: "I have a herniated disc that causes severe pain when I stand for more than 30 minutes, and my job requires standing at a cash register for eight hours."

You will also be asked whether you have filed for any other disability benefits, such as Social Security Disability Insurance (SSDI) or workers' compensation. Answer honestly; SDI coordinates with these programs, and they will find out anyway.

Documents to gather before you file

Collect medical records that show when your condition started and how it affects your ability to work. This typically includes doctor's visit notes from around the time you became unable to work, test results or imaging (X-rays, MRI scans), and any diagnoses your doctor has documented. If you see a specialist — a cardiologist, orthopedic surgeon, or psychiatrist — include their notes as well.

You will also need proof of your work history: your most recent pay stubs, a letter from your employer stating when you stopped working or reduced your hours, or tax returns if you are self-employed. If you have been out of work for several months, a recent pay stub may not exist; in that case, bring an employment verification letter from your employer or your final check.

Have your Social Security number and driver's license or state ID ready. If you are filing on behalf of someone else — a family member who cannot manage the paperwork — you will need a signed authorization form from that person.

How to file online, by mail, or in person

To file online, visit the SDI website and create an account or log in if you already have one. You will answer the same questions as Form DI 1, then upload your medical records and work documents as PDF or image files. The system will confirm receipt when ready and give you a case number to track your process.

If you prefer to mail the form, print Form DI 1 from the SDI website, fill it out by hand or typewriter, and attach copies of your medical records and employment verification. Do not send originals — keep those for your records. Mail it to the address shown on the form. Processing by mail typically takes longer than online filing because the form must be scanned and entered into the system by hand.

To file in person, locate your nearest EDD office using the office locator on the state website. Bring the completed form, your documents, and a photo ID. Staff can answer questions while you are there, though they cannot advise you on whether you will be approved.

What happens after you submit the form

Once SDI receives your process, they will send you a notice with your case number and the date they received it. This notice also lists what documents they still need from you. If your medical records are incomplete, they will request them from your doctors directly, which can add two to four weeks to the process.

An SDI examiner will review your medical evidence and work history to decide whether your condition prevents you from working. This review typically takes two to three weeks if all documents are in. If SDI approves your claim, they will notify you by mail and your benefits will begin. If they deny it, the notice will explain why and tell you how to request reconsideration or appeal.

While your case is being reviewed, you can check its status online using your case number, or call the SDI customer service line. Response times vary, but you should expect to wait at least two weeks before any decision is made.

If you need to report a change while receiving SDI

If you are already receiving SDI and your situation changes — you return to work part-time, your condition improves, or you move — you must report it using Form DI 3. SDI will reduce or stop your benefits if you earn more than a certain amount per week, so reporting work income promptly protects you from overpayment and the debt that follows.

You can file Form DI 3 online, by mail, or in person using the same methods as Form DI 1. If your medical condition has improved, include updated medical records showing the improvement. If you have returned to work, include recent pay stubs or a letter from your employer stating your hours and pay.

Frequently Asked Questions

Can I file the form if I am still working but working fewer hours?

Yes. SDI covers partial disability — you can work part-time and still receive benefits if your condition prevents you from working full-time. Report your current hours and income on the form, and SDI will calculate a reduced benefit amount. If you earn more than a weekly threshold (which changes yearly), your benefits may be reduced or stopped.

What if my doctor will not provide medical records?

SDI will request records directly from your healthcare providers once you file. If a provider does not respond, SDI may deny your claim based on insufficient medical evidence. Contact your doctor's office and ask them to send records to SDI; you can also sign a release form authorizing SDI to obtain them. If your doctor has retired or closed their practice, explain this in writing when you file.

Do I need a lawyer to file the form?

No. The form itself is straightforward and you can file it without legal help. However, if SDI denies your claim and you want to appeal, some people find it helpful to consult an attorney or advocate who specializes in disability claims. Many offer free initial consultations.

How long does it take to hear back after I file?

If all your medical records are on file, SDI typically makes a decision within two to three weeks. If they need to request records from your doctors, add two to four weeks. You can check your case status online using your case number at any time.

What if I file the form but then return to full-time work before SDI decides?

Contact SDI and let them know you have returned to work. You can withdraw your process, or SDI may deny it because you are no longer disabled. If you later become unable to work again, you can file a new process.
