If a medical condition is making it difficult to work, you may be wondering whether to apply for SSDI or SSI. The names sound similar, and both programs are administered by the Social Security Administration. But they have different eligibility requirements.

SSDI generally depends on your work history and disability insurance coverage. SSI depends on limited income and resources, along with age, blindness, or disability requirements. Some people qualify for both.

Understanding these differences can help you take the next step with greater confidence.

What Is SSDI?

Social Security Disability Insurance (SSDI) provides monthly benefits to eligible people whose medical conditions prevent them from working at the level Social Security considers substantial gainful activity.

For an SSDI claim based on your own earnings record, you generally must have worked long enough—and recently enough—in employment covered by Social Security. Younger workers may qualify with fewer work credits.

Your benefit amount is based on your Social Security earnings record. SSDI does not have SSI’s resource limit.

You can learn more through SSA’s explanation of how to qualify for Social Security disability benefits.

What Is SSI?

Supplemental Security Income (SSI) provides monthly payments to eligible adults and children with limited income and resources who meet the program’s other requirements.

You may qualify if you:

• Have a qualifying disability;
• Are blind; or
• Are age 65 or older.

People applying based on age 65 or older do not have to establish disability. Children are evaluated under separate childhood disability rules.

Unlike SSDI, SSI does not require your own work history. However, SSA reviews financial circumstances and other eligibility requirements.

Read SSA’s current guidance on who can get SSI.

SSDI vs. SSI at a Glance

Can You Receive SSDI and SSI Together?

Yes. Some people qualify for both programs, which SSA calls “concurrent” benefits.

For example, someone with a limited SSDI benefit may also qualify for SSI if they meet the financial and other requirements. However, SSDI generally counts as income when SSA calculates SSI. You should not expect to receive the full amount of each benefit added together.

SSA explains concurrent eligibility in its overview of SSDI and SSI disability programs.

Does My Diagnosis Automatically Qualify Me?

A diagnosis is an important starting point, but SSA also needs evidence showing the severity of your condition and how it affects your ability to function.

For adult disability claims, the medical condition generally must prevent substantial gainful activity and have lasted—or be expected to last—at least 12 consecutive months, or be expected to result in death. You do not have to wait 12 months to apply if your condition is expected to meet that duration requirement.

Your records and application should explain limitations such as difficulty:

• Sitting, standing, walking, lifting, or using your hands.
• Remembering instructions or maintaining concentration.
• Managing interactions or changes in routine.
• Completing tasks consistently and maintaining attendance.

Describe what happens when you attempt an activity, how long you can sustain it, and whether you need assistance, breaks, or recovery time.

What If You Haven’t Worked Recently?

Do not assume you have no options.

Your work history and the date your disability began can affect SSDI eligibility. SSI may be an option if you meet its financial and other requirements. Certain people may also qualify for benefits on a parent’s or deceased spouse’s Social Security record under separate rules.

A review of your circumstances can help identify which programs should be considered.
