What is the difference between SSI and SSDI?
SSDI (Social Security Disability Insurance) is based on your work history and the Social Security taxes you paid. You must have earned enough work credits — generally 40 credits, 20 earned in the last 10 years. SSI (Supplemental Security Income) is need-based and does not require a work history. SSI is available to adults and children with limited income and resources who are disabled, blind, or 65 or older.
What are the income and asset limits for SSI?
SSI has strict financial eligibility limits. In 2025, you generally cannot have more than $2,000 in countable resources ($3,000 for couples). Income limits are also low — the SSA counts both earned income (wages) and unearned income (Social Security, pensions). Some assets are excluded: your primary home, one vehicle, household goods, and certain retirement accounts.
Can I receive both SSI and SSDI at the same time?
Yes. If you qualify for SSDI but your benefit amount is very low (below the SSI federal benefit rate, currently $943/month in 2025), you may also qualify for SSI to supplement your SSDI payment. This is called receiving "concurrent benefits." SSI fills the gap between your SSDI payment and the SSI maximum benefit rate.
What medical conditions qualify for SSI or SSDI?
Both programs use the same medical standard: your condition must prevent you from doing any substantial gainful activity (SGA) and must have lasted or be expected to last at least 12 months or result in death. The SSA's Blue Book lists hundreds of qualifying conditions, including musculoskeletal disorders, cardiovascular conditions, mental disorders, cancer, and neurological disorders. Conditions not in the Blue Book can still qualify through a medical-vocational analysis.
What is the Substantial Gainful Activity (SGA) limit?
SGA is the earnings threshold above which the SSA considers a person capable of working. In 2025, the SGA limit is $1,550/month for non-blind individuals and $2,590/month for blind individuals. If you earn more than the SGA amount, you generally do not qualify for disability benefits, regardless of your medical condition.
How do I apply for SSI?
Apply for SSI by calling 1-800-772-1213, visiting your local Social Security office, or applying online at ssa.gov/ssi for certain applicants. You will need to provide: proof of age (birth certificate); Social Security card; proof of citizenship or immigration status; bank account information; information about income and resources; and medical records documenting your disability. The SSA will also ask you to complete a Disability Report (SSA-3368).
How do I apply for SSDI?
Apply for SSDI online at ssa.gov/applyfordisability, by calling 1-800-772-1213, or at your local Social Security office. You will need: your Social Security number; birth certificate; work history for the past 15 years; W-2s or self-employment tax returns; medical records; names and contact information of all treating doctors; and a list of all medications. The process typically takes 3–6 months for an initial decision.
What happens if my SSI or SSDI application is denied?
Most initial applications are denied. The appeals process has four levels: Reconsideration (request within 60 days using SSA-561); Hearing before an Administrative Law Judge (request within 60 days of Reconsideration denial using SSA-501); Appeals Council Review; and Federal Court. The ALJ hearing level has the highest approval rate — roughly 45–55% of cases are approved at that stage.
How much does SSI pay per month?
The federal SSI benefit rate in 2025 is $943/month for an individual and $1,415/month for a couple. Your actual payment may be lower based on income and living arrangements, or higher in states that provide a state supplement. SSI benefits are automatically adjusted each January for cost-of-living increases.
How much does SSDI pay per month?
SSDI benefits are calculated based on your average lifetime earnings covered by Social Security — not your disability or financial need. The average SSDI payment in 2025 is approximately $1,537/month. The SSA provides a Social Security Statement on your my Social Security account (ssa.gov/myaccount) that shows your estimated SSDI benefit amount.
Does SSI or SSDI come with health insurance?
Yes. SSDI recipients automatically receive Medicare after a 24-month waiting period from the month they are entitled to benefits. SSI recipients in most states are automatically enrolled in Medicaid. Concurrent beneficiaries (receiving both SSI and SSDI) may have both Medicaid and Medicare. Many SSDI recipients also qualify for Medicaid during the 24-month Medicare waiting period through their state's disability Medicaid program.
Can children qualify for SSI?
Yes. Children under age 18 can receive SSI if they have a medically determinable physical or mental condition that causes "marked and severe functional limitations" and the family's income and resources are within SSI limits. The SSA evaluates a child's disability under a separate standard from adults. Common qualifying childhood conditions include Down syndrome, cerebral palsy, severe intellectual disability, and childhood cancer.
