SSDI is a federal program that pays monthly benefits to people who cannot work because of a disability
SSDI stands for Social Security Disability Insurance. It is a program run by the Social Security Administration that sends monthly payments to people whose medical condition prevents them from working. The money comes from payroll taxes you and your employer paid into Social Security while you were working.
SSDI is different from other disability programs. It is not based on how much money you have or don't have. It is based on your work history — specifically, whether you paid enough into Social Security through your job. If you meet the work requirements and have a condition that meets Social Security's definition of disability, you can receive SSDI payments.
The program also covers certain family members. If you are approved for SSDI, your spouse, ex-spouse, or children may be able to receive benefits based on your work record, even if they have never worked.
Key Takeaways
- SSDI pays monthly cash benefits to people who cannot work due to a medical condition that is expected to last at least 12 months or result in death.
- You must have worked long enough and recently enough to have earned enough work credits, which you build by paying Social Security taxes through your job.
- Social Security will review your medical records, test results, and doctor's statements to decide whether your condition meets their definition of disability.
- Family members including your spouse, ex-spouse, and children may receive benefits based on your work record once you are approved.
- SSDI is separate from SSI (Supplemental Security Income), which is a needs-based program for people with low income and few resources.
How SSDI differs from other disability programs
SSDI is often confused with SSI (Supplemental Security Income), but they are two separate programs. SSI is for people with low income and limited resources, regardless of work history. SSDI is for people who have worked and paid into Social Security. You cannot receive both at the same time, though you may switch from one to the other under certain circumstances.
SSDI is also different from workers' compensation or short-term disability insurance. Those programs typically cover injuries or illnesses that happen on the job or are expected to heal within a set time. SSDI covers any medical condition — whether it happened at work or not — as long as it prevents you from working and is expected to last at least 12 months or result in death.
Some people receive SSDI while also collecting unemployment benefits or workers' compensation, depending on the state and the specific circumstances. The rules vary, so it is worth asking Social Security directly if you are receiving other benefits.
What Social Security means by "disability"
Social Security has a strict definition of disability. Your condition must prevent you from doing any substantial work — not just your current job, but any job you could reasonably do given your age, education, and work experience. The condition must be expected to last at least 12 months or result in death.
Social Security does not approve SSDI based on your own statement alone. They will request medical records from your doctors, hospitals, and any specialists you have seen. They may order their own medical examination. They look for objective evidence — test results, imaging, lab work, clinical notes — not just your description of pain or fatigue.
Some conditions are on Social Security's list of conditions that automatically meet the disability standard if you have the right medical evidence. These are called "compassionate allowances" and include conditions like terminal cancer, ALS, and severe intellectual disability. Even if your condition is on the list, you still need to provide the medical evidence that shows you have it.
The work credits you need to may have access to
To receive SSDI, you must have earned enough work credits through your job. You earn one work credit for every $1,730 of wages you earn in a year (this amount changes each year). You can earn up to four work credits per year.
How many credits you need depends on your age when you become disabled. If you become disabled before age 24, you generally need 6 credits earned in the 3 years before you became disabled. If you are between 24 and 31, you need credits for half the time between age 21 and when you became disabled. If you are 31 or older, you typically need 40 credits total, with at least 20 earned in the 10 years before you became disabled.
The exact requirement depends on your age and when you last worked. Social Security can tell you how many credits you have and how many you need. You can check your work record online through your Social Security account, or call Social Security at 1-800-772-1213 to ask.
How the SSDI decision process works
When you submit your SSDI request, Social Security sends it to a state agency called Disability information Services (DDS). This agency reviews your medical records and decides whether your condition meets Social Security's definition of disability. The DDS is not part of Social Security's local office — it is a separate state agency that handles all disability decisions in your state.
The DDS will contact your doctors and ask for your medical records. They may order a consultative examination — a medical exam paid for by Social Security — if they need more information. This process typically takes 3 to 6 months, though it can take longer if your case is complex or if records are hard to obtain.
If DDS denies your request, you have the right to appeal. Most people who are denied the first time are approved on appeal, especially if they provide additional medical evidence. You can appeal on your own or with help from a representative.
What happens after you are approved for SSDI
Once you are approved, Social Security will tell you when your benefits start. There is a 5-month waiting period from the date your disability began — you do not receive payments for those first 5 months. After that, you receive a monthly payment. The amount depends on your work record and earnings history.
While you receive SSDI, you can work part-time and earn a small amount without losing your benefits. Social Security has a program called Trial Work Period that lets you test your ability to work for 9 months without any reduction in benefits. After that, there is a 36-month period where you can earn more money and still receive some benefits, depending on how much you earn.
You must report any changes to Social Security, including if you start working, if your medical condition improves, or if you move. Your benefits can continue as long as your condition prevents you from working and you meet the other program rules.
Family members who can receive benefits on your record
If you are approved for SSDI, certain family members may receive benefits based on your work record. Your spouse can receive benefits at any age if they are caring for your child who is under 16, or at age 62 or older. Your ex-spouse can receive benefits at age 62 or older if you were married for at least 10 years.
Your unmarried children can receive benefits until age 19 if they are in high school full-time, or until age 18 if they are not in school. Children who were disabled before age 22 can receive benefits for life, as long as they remain disabled by Social Security's definition.
The total amount paid to your family cannot exceed a certain limit, which is usually 150 to 180 percent of your benefit amount. If your family members' combined benefits would exceed this limit, each person's payment is reduced proportionally.
Frequently Asked Questions
Can I get SSDI if I have never worked?
No. SSDI requires work credits earned through a job where you paid Social Security taxes. If you have never worked or did not work long enough, you may be able to receive SSI instead, which is a needs-based program. SSI does not require a work history, but it does have income and resource limits.
What if my condition is not on Social Security's list?
Most conditions are not on the list. Social Security will still review your medical evidence and decide whether your condition prevents you from doing any substantial work. Having a condition that is not on the list does not mean you cannot receive SSDI — it just means the decision takes longer and requires more detailed medical evidence.
Can I work part-time while receiving SSDI?
Yes. You can work and earn money while receiving SSDI, as long as your earnings stay below a certain limit (called substantial gainful activity). In 2024, that limit is $1,550 per month. You can also use the Trial Work Period to test your ability to work for 9 months without any reduction in benefits.
How long does it take to get approved for SSDI?
The initial decision usually takes 3 to 6 months. If you are denied and appeal, the appeal process can take several more months. Some appeals go to a hearing before an administrative law judge, which can add another 6 to 12 months. Having strong medical evidence from the start can speed up the process.
What is the difference between SSDI and SSI?
SSDI is based on your work history and the taxes you paid. SSI is based on your current income and resources. You cannot receive both programs at the same time. SSDI has no income or resource limits, while SSI does. If you have worked enough to may have access to for SSDI, you will receive SSDI instead of SSI.
