Social Security Disability Insurance and Supplemental Security Income are two separate programs that provide monthly payments to people with disabilities. While they serve similar purposes, they have different rules about who can receive benefits and how much money they provide.

SSDI is based on your work history and the Social Security taxes you or a family member paid into the system. To receive SSDI, you must have worked and paid into Social Security for a certain number of years. The amount you receive depends on your work record and earnings history. According to the Social Security Administration, approximately 8.2 million people received SSDI benefits as of December 2023, with an average monthly payment of $1,550.
SSI is a needs-based program that does not require a work history. Instead, SSI looks at your current financial situation. To receive SSI, you must have limited income and resources. As of December 2023, about 7.3 million people received SSI benefits, with an average monthly payment of $943. The income and resource limits change each year. For 2024, the monthly income limit for SSI is $1,943 for individuals and $2,915 for couples, though some income is not counted toward this limit.
Both programs require that you have a medical condition that prevents you from working. The Social Security Administration defines disability as a condition that is expected to last at least 12 months or result in death. This is stricter than many other disability definitions you might encounter.
Practical takeaway: Learning the differences between SSDI and SSI helps you understand which program may be relevant to your situation and what documentation you might need to gather.
Your Social Security statement shows your earnings history and estimates of potential benefits. Checking this information regularly helps you catch errors and understand what benefits you might receive. The Social Security Administration maintains records of all wages you earned and Social Security taxes paid on your behalf.

You can create an account on the official Social Security website at ssa.gov to view your personal Social Security statement online. The account registration process asks for personal information like your name, date of birth, Social Security number, and address. Once you verify your identity, you can see your complete earnings record going back to 1937.
Your earnings record shows year-by-year information about your wages and the Social Security taxes paid. This is important because disability benefits are calculated based on your average earnings over your working years. The Social Security Administration uses your 35 highest-earning years to calculate your Primary Insurance Amount, which is the base amount used to determine your SSDI benefit.
Common errors on earnings records include missing earnings, earnings credited to the wrong person, or earnings with wrong amounts. According to the Social Security Administration, you should report any errors you find within three years, three months, and 15 days from the year the wages were earned. If you find an error, you will need to provide documentation such as W-2 forms or tax returns to correct it.
If you don't have an online account, you can request a paper copy of your Social Security statement by calling 1-800-772-1213 (TTY 1-800-325-0778) or visiting your local Social Security office. The Social Security Administration also sends statements by mail to people age 60 and older who don't have an online account.
Practical takeaway: Reviewing your Social Security earnings record now can help you identify any discrepancies before you need to file a claim, making the process smoother later.
Medical evidence is the foundation of any disability claim. The Social Security Administration needs detailed information about your condition, how it affects your ability to work, and what treatment you have received. Understanding what types of evidence matter helps you gather the right documents.

Medical evidence includes office visit notes from your doctors, hospital discharge summaries, test results, imaging reports, and treatment records. The Social Security Administration looks for specific information in your medical records, such as the date your condition started, what symptoms you experience, what medications or treatments you receive, and your doctors' observations about how your condition limits your activities.
Different conditions require different types of evidence. For a respiratory condition like chronic obstructive pulmonary disease, Social Security wants to see pulmonary function test results and oxygen saturation measurements. For mental health conditions like depression or anxiety, they need documentation of your psychiatric treatment, therapy notes, and any standardized assessment scores. For back pain or arthritis, they want imaging results like X-rays or MRI scans along with documentation of physical limitations.
The recency of your medical evidence matters. Social Security generally prefers records from the past 12 months, though they will review older records if your condition has been stable. If you have not seen a doctor in a long time, getting evaluated before filing a claim strengthens your case. In 2023, the average Social Security disability claim took 3 to 6 months to process at the initial level, and medical records were the most frequently requested additional information from claimants.
You should gather records from all doctors who treat your condition, including primary care physicians, specialists, therapists, and any hospitalizations. Each medical provider may have different information. Your primary care doctor might document how your condition affects your daily functioning, while a specialist provides detailed clinical assessment of your condition itself.
Practical takeaway: Start gathering and organizing your medical records now, even if you're not ready to file a claim, so you have a complete picture of your medical history available when needed.
Once you submit a disability claim, your case goes through several stages of review. Understanding this process helps you know what to expect and what information might be requested from you.

At the initial level, the Social Security Administration reviews your application, medical evidence, work history, and other information to make a determination. A disability examiner and medical or psychological consultant review your case together. The examiner verifies your work history and other non-medical information, while the consultant reviews your medical records and determines whether your condition meets Social Security's definition of disability. This initial review typically takes 3 to 6 months.
During this time, you may receive requests for additional medical records, additional information about your work history, or records of any criminal convictions. You should respond to these requests within the timeframe given, typically 10 days. Failing to respond can result in your claim being denied for insufficient information.
The Social Security Administration makes one of four possible decisions at the initial level: approval, denial, approval of a different claim type than you filed for, or dismissal of your claim. In 2023, the national average approval rate for initial disability claims was 32 percent, though this varies by state and type of disability.
If your claim is denied, you have the right to file an appeal. The first level of appeal is called a Request for Reconsideration. This goes to a different disability examiner who has not reviewed your case before. You can submit additional medical evidence or other information with your appeal. The reconsideration process typically takes 3 to 5 months.
If you are denied again, you can request a hearing before an Administrative Law Judge. At this hearing, you can present evidence, have a representative speak on your behalf, and question any vocational or medical experts the Social Security Administration presents. According to Social Security data, approval rates at the hearing level are significantly higher, with approximately 60 percent of cases approved after a hearing.
Practical takeaway: Keep copies of everything you send to Social Security and document the dates you send it, so you have a record of what information you have provided.
Social Security has programs that allow people receiving disability benefits to work and earn money while still receiving some benefits. These programs are designed to help people transition back to work without losing all their support immediately.

The Trial Work Period is available to people receiving SSDI. During this period, which lasts up to 9 months, you can work and earn any amount of money without affecting your disability benefits. The only requirement is that your work is considered "substantial gainful activity," which for 2024 means earning at least $1,550 per month. Any month you earn less than $1,550 counts as a trial work month, even if you work multiple months. Once you use all 9 trial work months
