Essential SSDI Forms to Prepare

Here are the key documents and forms you’ll need when applying:

1. SSA-16: Application for Disability Insurance Benefits

This is the main application form for SSDI. It asks about your medical condition, work history, and basic personal details.

2. SSA-3368: Adult Disability Report

This form goes deeper into your disability, including:

• Diagnosed conditions
• Treatment providers
• Medications
• How your condition affects daily life and work

3. SSA-827: Authorization to Disclose Information

You must sign this form to allow SSA to contact your doctors, hospitals, and other sources to get your medical records.

Other Forms You May Need

Depending on your situation, SSA might request additional forms:

• SSA-3369: Work History Report – Details of your jobs over the last 15 years
• SSA-3373: Function Report – Describes how your condition limits your daily activities
• SSA-821 or SSA-820 – If you're working or self-employed, these assess your income and work activity

Where to Get the Forms

You can complete these forms:

• Online at SSA.gov
• By phone or in person at a Social Security office in Michigan
• With the help of an attorney, who can ensure all documentation is correct and complete

Why Accuracy Matters

Each form must be:

• Fully completed — missing details can delay your case
• Consistent — answers across all forms must match your medical records
• Clear and honest — exaggerating or minimizing symptoms can hurt your credibility
