Disability Insurance Covers Lost Wages When You Cannot Work

Social Security Disability Insurance (SSDI) replaces part of your income if a medical condition prevents you from working. You do not receive a lump sum or one-time payment — instead, you get a monthly check for as long as you remain disabled and meet the program's rules.

SSDI is different from workers' compensation (which covers job injuries) and from Supplemental Security Income or SSI (which is based on income and assets, not work history). To receive SSDI, you must have worked long enough and paid Social Security taxes during those years. The Social Security Administration (SSA) calls this having enough work credits.

The amount you receive each month depends on your earnings record — specifically, how much you earned in the years you worked. A higher lifetime earnings history means a higher monthly payment. Your family members may also receive payments based on your work record if you are approved.

Key Takeaways

  • SSDI requires both a severe medical condition that prevents work and a sufficient work history with Social Security tax contributions.
  • You must have earned enough work credits before your disability began, with the number required depending on your age at the time you became disabled.
  • Monthly payments are based on your lifetime earnings record, not on how much money you have or your current expenses.
  • The SSA reviews your case periodically to confirm you still meet the disability definition, and payments stop if you return to substantial work.

How Work Credits Connect to SSDI may be able to access

Work credits measure how long you have worked and paid into Social Security. You earn one credit for each quarter (three-month period) in which you earned at least a certain amount in wages — in 2024, that amount is $1,705 per quarter, though this figure changes yearly. You can earn a maximum of four credits per year, regardless of how much you earn above that threshold.

SSDI requires you to have earned a minimum number of credits before your disability began. For someone under 24, the requirement is lower — typically six credits earned in the three years before disability. For someone 24 to 31, you generally need credits equal to half the quarters between age 21 and the age you became disabled. For someone 31 or older, you usually need 40 credits total, with at least 20 earned in the 10 years before disability.

If you have not worked long enough to meet these requirements, you cannot receive SSDI, even if your medical condition is severe. In that case, you may be able to receive SSI instead, which does not require a work history but does have strict income and asset limits.

The Medical Condition Must Prevent Substantial Work

Having a diagnosis is not enough. The SSA must find that your condition prevents you from doing any substantial work — meaning work that pays more than a set monthly amount. In 2024, that amount is $1,550 per month for non-blind individuals and $2,590 for blind individuals. If you earn more than this while receiving SSDI, your benefits will be reduced or stopped.

The SSA evaluates whether your condition meets or equals one of its listed impairments in the Blue Book, a reference guide of conditions the agency recognizes as disabling. If your condition is not listed, the SSA will assess whether it prevents you from doing your past work or any other work that exists in the economy, considering your age, education, and work skills.

You do not have to be unable to work at all — you must be unable to work at a substantial level. This distinction matters because some people with disabilities can do part-time or lower-wage work. SSDI allows you to earn a small amount (called the trial work period) without losing benefits, but only for nine months within a rolling 60-month period.

How the SSA Verifies Your Work History

The SSA has a record of your earnings and work credits based on the Social Security taxes your employers withheld from your paychecks. When you file for SSDI, the agency pulls your earnings record automatically — you do not have to provide pay stubs or tax returns for every year you worked, though you may need to provide them if there are gaps or discrepancies.

If you are self-employed, the SSA uses your tax returns to calculate credits. Self-employed earnings are treated differently: you need $1,705 in net self-employment income per quarter to earn one credit, and the SSA counts your income based on what you reported to the IRS.

If you worked outside the United States or for an employer who did not pay Social Security taxes (such as some government employees hired before 1984), those years may not count toward your credits. You can request a statement of your earnings record from the SSA to verify what they have on file before you file for SSDI.

What Happens to Your Benefits If You Return to Work

SSDI includes protections that allow you to test your ability to work without when ready losing all your benefits. The trial work period lets you work and earn any amount for nine months (not necessarily consecutive) within a 60-month window without affecting your benefits. After the trial work period ends, the SSA enters an extended may be able to access period of 36 months during which you can still receive benefits in any month your earnings fall below the substantial work level.

If your earnings stay above the substantial work level for a full month, your benefits stop for that month. If you later drop below that level again, your benefits restart without a new process — the SSA calls this a reinstatement. You have five years from the month your benefits stopped to request reinstatement based on your prior approval.

You must report any work activity to the SSA, including self-employment, volunteer work that you are paid for, and unpaid work-related activities. Failing to report work can result in overpayments that you will be required to repay.

Periodic Reviews Confirm You Still Meet the Definition

SSDI is not permanent. The SSA conducts periodic reviews — called continuing disability reviews (CDRs) — to confirm that your condition still prevents substantial work. How often you are reviewed depends on whether your condition is expected to improve. If improvement is expected, you may be reviewed every one to three years. If improvement is not expected, reviews may happen every five to seven years or less frequently.

During a review, the SSA requests updated medical evidence from your doctors. You must provide this information or the SSA may stop your benefits. If the SSA finds that your condition has improved enough that you can work, it will send you a notice explaining the decision and your right to appeal.

If your benefits are stopped and you disagree, you can request reconsideration within 60 days of the notice. You can also request a hearing before an administrative law judge if reconsideration is denied.

Family Members May Receive Benefits on Your Record

If you are approved for SSDI, your spouse, ex-spouse (if married at least 10 years), and unmarried children under 19 (or 19 if still in high school) may receive benefits based on your work record. Each family member receives their own monthly payment, calculated as a percentage of your benefit amount.

There is a family maximum — a cap on the total amount all family members can receive combined. This maximum is usually 150 to 180 percent of your own benefit amount. If the total would exceed the maximum, each family member's payment is reduced proportionally.

Family members do not need their own work history to receive benefits. They must meet age or disability requirements, and they cannot be working above the substantial work level. If a family member works and earns above that threshold, their portion of the benefit is reduced or stopped.

Frequently Asked Questions

Can I get SSDI if I have not worked in several years?

Only if you earned enough work credits before you stopped working. The SSA looks at whether you had the required credits at the time your disability began, not at the time you file. If you became disabled while still working or shortly after, you may have enough credits even if years have passed since then.

Does my age affect how much SSDI I receive?

Your age does not directly change your monthly payment amount. Your payment is based on your lifetime earnings record. However, age affects how many work credits you need: younger workers need fewer credits than older workers.

What if I worked for a railroad instead of a regular employer?

Railroad workers have their own retirement and disability system, the Railroad Retirement Board (RRB), separate from Social Security. If most of your work was in railroad employment, you file with the RRB instead of the SSA. If you have both railroad and non-railroad work, the SSA and RRB coordinate to determine which agency handles your claim.

Can I receive SSDI and workers' compensation at the same time?

Yes, but your SSDI payment may be reduced. If you receive workers' compensation for the same condition, the SSA offsets your SSDI benefit so that the combined amount does not exceed 80 percent of your average current earnings before disability. You must report all workers' compensation payments to the SSA.

What if the SSA says I do not have enough work credits?

You can request that the SSA review your earnings record for errors. If your record is correct and you do not have enough credits for SSDI, you may be able to receive SSI instead, which does not require work credits but has income and asset limits. You can file for both programs at the same time.
