What You Need to Apply for SSDI

Reduce the risk of delays by getting your documents together. You will need to provide Social Security with the following:

Your personal information 

Your Social Security number, date and place of birth, and bank account details for direct deposit if approved.

Your medical information 

This includes:

  • Names, addresses and contact details for all doctors, specialists and hospitals that have treated you
  • Dates of appointments
  • Names of medications you take 
  • Any medical records you already have access to

Your work history

The names and addresses of employers from the last five years, the dates you worked for each, and the date you stopped working due to your condition.

Having these ready before you begin means your application is more complete from the start, which is one of the most common reasons initial applications are delayed.

Use our SSDI screener to understand whether your situation meets the criteria or not.

After You Apply for SSDI: What to Expect

After you submit your application, Social Security sends it to your state’s Disability Determination Services (DDS) office, which reviews your medical evidence, and makes the initial decision on your claim.
1

The review period

DDS will contact your doctors and medical providers directly to gather records. The review process typically takes three to six months, though the timeline can extend if there is a backlog.

2

Keep doctors informed

Let the doctors treating you know that your SSDI claim is under review to ensure they respond promptly if DDS reaches out.

3

Receive the decision by mail

If approved, the letter will confirm your benefit amount and start date. If denied, the letter will explain why and outline your right to appeal. Most initial applications are denied, so a denial at this stage is not the end of your case.

Why Professional Help Can Make a Difference To Your Application

SSDI is a complex process where denials are not uncommon at first. Even if you qualify, your application may be denied if it doesn’t adequately show how your condition impacted your ability to work. Here’s how we can help:

  • Getting the evidence right. Social Security looks for specific documentation. Someone who knows the process can help you and your doctors present that evidence in a way that reflects your situation accurately and completely.
  • Having someone in your corner. From paperwork to hearings, having a knowledgeable advocate means you are not interpreting the requirements alone. There are no attorney fees unless your case is successful. 

Understanding your options even before you apply is crucial for getting your claim right.

Frequently Asked Questions

How can you apply for disability benefits?
You can apply for disability benefits through the Social Security Administration (SSA) online, by phone, or in person at your local SSA office. The online social security disability application is available at ssa.gov and is the fastest way to get started. You will need to provide medical records, work history, and personal identification. SSDI Answers and Disability Advocates Group can make the process significantly easier, helping you avoid common mistakes that lead to delays or denials.
You can apply for SSDI while working, but your earnings must fall below the SSA’s Substantial Gainful Activity (SGA) limit, which is $1,690 per month in 2026 for non-blind applicants. If you earn above this threshold, the SSA will generally find you ineligible regardless of your medical condition. If you are close to the limit, speaking with someone who offers help with SSDI applications can clarify how your income may affect your claim.
SSI and SSDI are two separate programs with different eligibility requirements. SSDI is based on your work history and the Social Security credits you have earned, while SSI is a needs-based program for people with limited income and resources regardless of work history. If you have worked consistently and paid Social Security taxes, SSDI is typically the right starting point. If you have little or no work history, SSI may be your primary option.

Yes, you can apply for SSI and SSDI at the same time. This is called a concurrent application and is common when someone meets the disability criteria for SSDI but may receive a low monthly benefit. In those cases, SSI can supplement the SSDI payment. The SSA will assess both applications together when you apply for social security and disability through a single submission.

You can apply for SSDI once your disabling condition has prevented you from working, or is expected to do so for at least 12 months. There is no mandatory waiting period before submitting your application, though a five-month waiting period applies before benefits can be paid. Applying early is advisable because the review process can take several months. 

Veterans apply for SSDI through the Social Security Administration, not the Department of Veterans Affairs. The process follows the same steps as a standard online social security disability application at ssa.gov, but veterans who became disabled while on active duty on or after October 1, 2001 may qualify for expedited processing. Having a VA disability rating does not automatically qualify you for SSDI, though your VA medical records can serve as strong supporting evidence for your claim.
There is no limit to how many times you can apply for SSDI. If your initial application is denied, which happens in many cases, you have the right to appeal through several stages: reconsideration, a hearing before an Administrative Law Judge, Appeals Council review, and federal court. Many applicants who are ultimately approved were denied at least once. Rather than reapplying from scratch after a denial, pursuing the appeals process is generally the more effective route.
You can complete the online application on the SSA website. The process involves answering questions about your medical conditions, work history, education, and daily activities. You will also need to provide information about your healthcare providers so the SSA can request your medical records. The online application saves your progress, so you can complete it across multiple sessions if needed. Some people find the application overwhelming, and SSDI Answers offers free guidance to help you navigate the process with confidence. In addition, working with experienced SSDI advocates like Disability Advocates Group can help ensure it is completed accurately and thoroughly from the start.
An initial SSDI application typically takes six to eight months for a decision, though timelines vary by state and case complexity. If your application is denied and you appeal to the hearing level, the total process can take one to two years or longer. Submitting thorough documentation from the start, including detailed medical records and physician statements, can help reduce unnecessary delays. Getting help with your SSDI application from an experienced advocate or attorney may also improve both speed and outcomes.
