SSDI vs SSI: Which program fits your situation?
If a health condition keeps you from working, you may be wondering whether SSDI or SSI is the right place to start. The names sound alike, but the programs have different rules about work history, income, and what you own.
SSDI is insurance workers pay for through payroll taxes. SSI is based on financial need and does not require a work history. You may qualify for one or both programs, and applying directly with Social Security is always free.

The main difference: work history vs financial need
Social Security Disability Insurance, or SSDI, covers eligible workers who paid into Social Security through payroll taxes. You need enough work credits, including recent work, and a condition that meets Social Security’s disability rules. SSDI generally does not limit your savings or count a spouse’s income when deciding your eligibility as a disabled worker.
Supplemental Security Income, or SSI, helps people with limited income and resources who are disabled, blind, or age 65 or older. Resources are things you own, such as cash and certain property. You do not need work credits, and some things, including the home you live in, generally do not count toward the resource limit.
Both programs are run by Social Security. SSI has additional residency and citizenship or eligible immigration status rules, so financial need alone does not establish eligibility.
How Social Security decides whether you have a disability
For adults applying based on disability, SSDI and SSI generally use the same medical standard. Your condition must prevent substantial work and be expected to last at least 12 months or result in death. You do not have to wait until you have been unable to work for a full year before applying.
Social Security considers your work activity, how serious your condition is, and whether it meets its medical requirements. It also considers whether you can do past work or adjust to other work, based on your limitations, age, education, and work experience. A diagnosis alone does not establish eligibility.
People age 65 or older may qualify for SSI without proving a disability if they meet the other rules. SSI also covers eligible children with disabilities, using different medical rules from those for adults.

Which program should you look into?
SSDI may fit if you have a long-term disabling condition and enough recent work covered by Social Security. Many adults need to have worked about five of the past ten years, along with meeting an overall work-credit requirement. Younger workers may qualify with less work.
SSI may fit if you have little income and few countable resources, even if you have never worked or have not worked recently. Social Security may count some income and resources from a spouse you live with or, for a child, from parents.
You can qualify for SSDI and SSI at the same time if you meet both programs’ rules. Ask Social Security to check both rather than assuming you must choose just one.
What evidence should you gather?
For a disability claim, gather the names and contact details of your doctors, treatment dates, diagnoses, test results, and medication list. Include information about side effects and specific limits, such as difficulty standing, concentrating, lifting, or keeping a regular schedule.
Prepare a work history that describes your job duties, hours, and when your condition affected your work. Your my Social Security account at ssa.gov can help you review your earnings record. Tell Social Security about missing or incorrect earnings.
For SSI, also gather records of income, bank accounts, other resources, and living arrangements. You can start the application process even if you do not yet have every medical record. Social Security can request records from your providers.

Call 1-888-663-7044Common mistakes that can cause confusion
Do not assume that being out of work automatically qualifies you for disability, or that a diagnosis guarantees approval. Explain what your condition prevents you from doing and how often those problems happen. If you cannot afford treatment or face other barriers to care, tell Social Security.
Do not assume that any work automatically rules you out, either. Social Security looks at earnings and the circumstances of your work. Report work activity honestly and ask how it affects your application.
Also, do not treat a website’s screening rules as Social Security’s final eligibility rules. Screening tools may serve a narrower group, and only Social Security can decide whether you qualify.
Your next step: check your options and apply
Visit ssa.gov or contact Social Security to discuss SSDI, SSI, or both. Applying directly with Social Security is always free. You do not need an attorney or advocate to apply.
QualifySSDI is an independent, non-government service that helps workers check whether they may qualify for SSDI. Its screening asks about age, whether you are currently employed, and whether you worked about five of the past ten years. It also asks whether you have a diagnosed condition expected to last at least 12 months, with current treatment or prescribed medication.
The screening also checks whether you already receive Social Security benefits or work with an attorney or advocate. These are QualifySSDI’s screening criteria, not a complete statement of Social Security’s rules. QualifySSDI is not Social Security or a law firm, and a screening result does not guarantee approval.
However your claim is going, a short call costs nothing and often saves months. Speak with an advocate today.
Call 1-888-663-7044Common questions
What is the difference between SSDI and SSI?
SSDI is insurance you pay for through payroll taxes, and eligibility depends on your work record and disability. SSI is based on limited income and resources and does not require a work history. SSI serves eligible people who are disabled, blind, or age 65 or older.
Can you get SSDI and SSI at the same time?
Yes, if you meet the rules for both programs. Social Security reviews your work record, disability, income, and resources to determine eligibility. Ask to be considered for both programs when you apply.
Can I get disability if I have never worked?
You generally cannot qualify for SSDI on your own work record without enough covered work. You may qualify for SSI if you meet its financial and other eligibility rules. Some people may also qualify for disability benefits on a parent’s or deceased spouse’s work record under separate rules.
Does my spouse’s income affect SSDI or SSI?
Your spouse’s income generally does not affect SSDI eligibility on your own work record. For SSI, Social Security may count some of a spouse’s income and resources if you live together. Explain your household situation when you apply.
Is SSI easier to get than SSDI?
For adults applying based on disability, the programs generally use the same medical standard. SSI adds financial eligibility rules, while SSDI requires enough work credits. People applying for SSI at age 65 or older do not have to establish a disability.
How do I apply for SSDI or SSI?
Start at ssa.gov or contact Social Security to learn which application steps apply to you. Have your medical provider details, work history, and any needed financial records ready, but do not delay just because something is missing. Applying directly with Social Security is always free.
