How to Fill Out the Social Security Disability Application (Step-by-Step Guide)

How to Fill Out the Social Security Disability Application (Step-by-Step Guide)

Filing for Social Security Disability can feel overwhelming — especially if you're sick, injured, or unable to work. But if you’re applying for SSDI (Social Security Disability Insurance) or SSI (Supplemental Security Income) in 2025, this step-by-step guide will walk you through the process.

At Crossroads Disability, we help people like you file and win disability claims every day — and we’re here to make the process as smooth and stress-free as possible.

Step 1: Decide How You’ll Apply

You can apply:

• Online via the SSA website (ssa.gov)
• By phone: 1-800-772-1213
• In person at your local Social Security office

Applying online is often the fastest and most convenient option, but it can still be confusing — especially if you’re not sure what to say.

Step 2: Gather the Right Information

To complete the application, you’ll need:

• Your Social Security number
• Information about your medical conditions
• Names and contact info for all doctors and clinics
• List of all medications you take
• Work history for the past several years
• Details about education, training, and skills
• Any documents related to workers’ comp, military service, or long-term disability

Pro tip: Get medical records organized before applying — SSA won’t automatically collect everything.

Step 3: Understand the Main Forms

SSA will ask you to complete several key forms:

SSA-16: Application for SSDI

• Your personal info, work history, and dates you stopped working
• Any benefits you’re currently receiving

SSA-3368: Adult Disability Report

• The heart of your case — describes your conditions and how they affect your ability to work
• Requires details about doctors, symptoms, treatments, and daily limitations

SSA-827: Medical Release Form

• Authorizes SSA to request records from your healthcare providers

Step 4: Avoid Common Mistakes That Can Cause Denials

Most people are denied at the initial application stage — but many denials are preventable. Watch out for these common pitfalls:

• Failing to list all conditions
• Leaving out medical providers or hospitals
• Describing symptoms vaguely
• Not explaining how your condition impacts daily functioning or work
• Applying while still working full-time

SSA doesn't just look at what conditions you have — they care how those conditions limit your ability to work full-time.

Step 5: Consider Getting Legal Help from the Start

You are allowed to apply on your own, but working with an experienced disability lawyer can make a big difference. At Crossroads Disability, we:

• Help you gather and organize medical evidence
• Fill out your application for you
• Submit all forms correctly and on time
• Follow up with SSA so you don’t have to

And — you don’t pay us anything unless we win your case.

Step 6: Know What Happens After You Apply

Once SSA receives your application:

1. A Disability Determination Services (DDS) office reviews it
2. They may request more info or schedule a consultative exam
3. You’ll receive a written decision in 3 to 6 months (on average)

If denied, you have 60 days to appeal — and we can help with that too.

Bonus: What If You Can’t Finish the Application?

If you start applying online and get stuck, don’t worry. You can save your progress and call us to help you finish — we’ll take it from there.
