SSDI is a federal insurance 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 (SSA), a federal agency. SSDI pays monthly cash benefits to workers who have a medical condition severe enough that they cannot do substantial work, and to certain family members of those workers.
The key word is "insurance." You do not explore for SSDI the way you might explore for welfare or food information. Instead, SSDI is funded by payroll taxes — the same taxes that fund regular Social Security retirement benefits. If you worked and paid those taxes, you have already paid into the system. SSDI is there if you become disabled before retirement age.
SSDI is different from SSI (Supplemental Security Income), which is a separate program for people with disabilities who have little or no work history or income. The two programs have different rules, different payment amounts, and different resource limits. This article covers SSDI only.
Key Takeaways
- SSDI requires that you have worked long enough and paid Social Security taxes, and that your medical condition prevents substantial work for at least 12 months.
- The Social Security Administration decides whether your condition meets their definition of disability, not your doctor alone.
- SSDI payments are based on your own work record, not on how severe your condition feels or how much money you need.
- Family members — including spouses, ex-spouses, and children — may receive benefits based on your work record even if they have never worked.
- You must report changes in your medical condition, work activity, and living situation to SSA, or your benefits can be stopped.
How SSDI differs from other disability programs
SSDI is one of several programs that help people with disabilities. Understanding which one applies to you matters because the rules are not the same.
SSI (Supplemental Security Income) is a needs-based program. It does not require a work history. SSI pays a federal base amount (which varies by state) to people with disabilities, blindness, or age 65 and older who have very little income or resources. If you have never worked or worked very little, SSI may be the program you need instead of SSDI.
Workers' Compensation covers injuries or illnesses that happen on the job. It is run by your state, not by Social Security. If your disability came from a work injury, you may be able to claim workers' compensation instead of or in addition to SSDI.
VA Disability Benefits are for military veterans with service-connected disabilities. The Department of Veterans Affairs runs this program separately from Social Security. You can receive both SSDI and VA benefits at the same time.
What "disability" means under SSDI rules
SSDI has a specific legal definition of disability. It is not the same as what your doctor might call a disability, and it is not based on how much pain you are in or how much your condition limits you in daily life.
Under SSDI rules, you have a disability if you have a medical condition (physical, mental, or both) that:
- Prevents you from doing substantial work — meaning work that earns more than a certain monthly amount (the amount changes each year, but in 2024 it is $1,550 per month for non-blind workers).
- Is expected to last at least 12 months, or is expected to result in death.
The SSA does not decide based on your job title or the job you had before. Instead, they ask whether your condition prevents you from doing any kind of substantial work that exists in the national economy, taking into account your age, education, and work skills. This is a high bar. Many people with serious medical conditions do not meet it because SSA determines they could still do some type of work.
How your work history affects SSDI may be able to access
SSDI is an insurance program, so you must have worked and paid Social Security taxes to be covered. SSA calls this having "insured status."
The basic rule is that you need 40 work credits, and at least 20 of those credits must have been earned in the 10 years before you became disabled. A work credit is earned by paying Social Security taxes on your wages — in 2024, you earn one credit for every $1,730 in wages (the amount changes each year). Most full-time workers earn four credits per year.
If you are younger than 31, the rules are different and usually easier to meet. If you became disabled before age 31, you may need only 20 work credits total, with half of them earned in the three years before you became disabled.
If you do not have enough work credits, you cannot receive SSDI. You may be able to receive SSI instead, if you meet that program's income and resource limits.
Who can receive benefits based on your SSDI record
SSDI is not just for the worker. Family members can receive benefits based on your work record, even if they have never worked themselves.
Your spouse can receive benefits at any age if they are caring for your child who is under 16 or disabled. A spouse age 62 or older can also receive benefits based on your record. The amount they receive is a percentage of your benefit amount.
Your ex-spouse can receive benefits if you were married for at least 10 years, you are at least 62 years old (or any age if caring for your disabled child), and you have been divorced for at least two years. Your ex-spouse does not need your permission.
Your 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. A child can receive benefits past age 18 if they became disabled before age 22 and remain disabled.
The total amount that can be paid to your entire family is usually between 150 and 180 percent of your own benefit amount. If family benefits would exceed that limit, each family member's payment is reduced proportionally.
What happens after you receive SSDI
Receiving SSDI is not permanent unless your condition is expected to never improve. SSA conducts periodic reviews to check whether you still meet the definition of disability. How often they review depends on whether your condition is expected to improve, stay the same, or get worse.
You must report certain changes to SSA. If you start working, even part-time, you must report it. If your medical condition improves, you must report it. If you move, marry, divorce, or have a child, you must report it. If you do not report changes, SSA can stop your benefits or demand repayment of overpayments.
If SSA decides you no longer meet the disability definition, they will send you a notice. You have the right to request reconsideration, and later to request a hearing before an administrative law judge. Many people win at the hearing stage even after being denied twice.
How SSDI payments are calculated
Your SSDI payment amount is based on your own earnings record, not on how much money you need or how severe your condition is. SSA calculates your "Primary Insurance Amount" (PIA) using a formula based on your average earnings over your working years.
The formula is progressive, meaning it replaces a higher percentage of earnings for workers who earned less. A worker who earned $20,000 per year will receive a higher percentage of that amount than a worker who earned $100,000 per year. However, there is a maximum SSDI benefit amount, which changes each year.
In 2024, the average SSDI benefit is around $1,550 per month, but individual amounts vary widely. You can see your own estimated benefit amount by creating an account on ssa.gov and viewing your Social Security Statement.
Frequently Asked Questions
Can I receive SSDI if I have never worked?
No. SSDI requires that you have worked and paid Social Security taxes. If you have never worked or do not have enough work credits, you may be able to receive SSI instead, which does not require a work history. SSI has strict income and resource limits, but it is available to people with disabilities who have little or no work record.
Does SSDI cover mental health conditions?
Yes. Mental health conditions including depression, anxiety, bipolar disorder, schizophrenia, and others can may have access to for SSDI if they are severe enough to prevent substantial work for at least 12 months. SSA evaluates mental health conditions using the same standard as physical conditions — can you do any substantial work despite the condition?
What is the difference between SSDI and regular Social Security retirement?
SSDI is for people who are disabled before retirement age. Social Security retirement is for people age 62 and older. At full retirement age, SSDI automatically converts to retirement benefits, but the payment amount usually stays the same. The programs are funded by the same payroll taxes, but the may be able to access rules are different.
Can I work while receiving SSDI?
You can do some work and still receive SSDI, but there are limits. In 2024, if you earn more than $1,550 per month, SSA may consider you able to do substantial work and stop your benefits. There are also work incentive programs that allow you to test your ability to work without when ready losing benefits, but you must report all work activity to SSA.
How long does it take to get a decision on an SSDI claim?
Initial decisions usually take three to five months, though some cases take longer. If SSA denies your claim, you can request reconsideration (another three to five months), then a hearing before a judge (usually six months to two years depending on your local hearing office's backlog). Many people are approved at the hearing stage after being denied initially.
