Before Social Security looks at your medical condition for SSDI, it usually checks your work record.
That check uses something called work credits. Credits come from jobs where Social Security taxes were taken out of your pay. If you do not have enough credits, Social Security generally cannot pay SSDI, even if your condition is serious.
This is general information. It is not legal or medical advice.
What a work credit is
You earn work credits when you work and pay Social Security taxes. Credits are based on how much you earn in a year, not on how many weeks you clocked.
In general, you can earn up to four credits in one year. The amount of earnings needed for each credit changes a little each year. Social Security publishes the current amount on its official website.
Credits stay on your record even if you change jobs or stop working for a while.
The two tests for SSDI
For disability benefits, Social Security generally looks at two work tests:
- A recent work test — enough credits in the years just before your disability began.
- A duration of work test — enough credits over your working life to show you worked long enough under Social Security.
Both matter in most adult claims. Special rules can apply in some cases, such as statutory blindness. Social Security decides how the rules fit your record.
The common rule for many adults
Many people who become disabled at age 31 or older need, in general, enough total credits for their age (often building toward 40 over a full career) and at least 20 credits in the 10 years right before their disability began.
People often hear this as "40 credits, with 20 in the last 10 years." That shorthand is close for many older workers, but the exact count depends on your age when the disability began.
Younger workers usually need fewer credits
If your disability began at a younger age, the recent work test is usually lighter.
In general, according to Social Security:
- Before age 24: You may need six credits earned in the three years before your disability began.
- Age 24 through 30: You generally need credit for working about half the time between age 21 and the time your disability began. For example, if disability began at age 27, that often means about three years of work (12 credits) out of the six years between ages 21 and 27.
- Age 31 or older: You generally need at least 20 credits in the 10 years immediately before your disability began, plus enough total credits for the duration of work test.
The duration of work test also rises with age. Social Security publishes tables with examples by age. Those tables are estimates and do not cover every situation.
When insured status can run out
Work credits do not always stay "active" for SSDI forever after you stop working.
In plain words: after you leave covered work, there can come a point when you no longer meet the recent work test. Social Security sometimes calls the end of that window your date last insured.
If that date has already passed, Social Security generally looks at whether your disability began while you were still insured. Medical evidence usually needs to show the condition met Social Security's rules by that time.
Checking your record after you stop working helps you see whether you still meet the recent work rules.
How to check your credits
The clearest way is to open a free my Social Security account on the Social Security Administration's official website. Your Social Security Statement shows your earnings by year and helps you see your work history.
Look for:
- Years with no earnings that you know you worked
- Years with amounts that look far too low
- Gaps that do not match your real jobs
If something looks wrong, gather W-2s, pay stubs, or tax returns and ask Social Security to review the record. Fixing errors early is easier than fixing them in the middle of a claim.
Checking your Statement is one of the basic steps before you file. Our guide on how to apply for SSDI for the first time covers that check in the wider application path.
If you do not have enough credits
Not having enough SSDI credits does not always mean there is no program for you.
SSI (Supplemental Security Income) is a different program. It is based on financial need and other rules, not on a long work record. Some people qualify for SSI, some for SSDI, and some for both in certain situations.
Read our guide on the difference between SSDI and SSI if you are unsure which path fits.
Credits are only the first gate
Enough credits get you past the work-history check. They do not decide the medical side of your claim.
Social Security still uses a strict definition of disability. In general, your condition must keep you from doing substantial work and must have lasted, or be expected to last, at least 12 months, or be expected to result in death. Gaps in work history can also cause problems later; see why SSDI claims get denied.

You can review your Statement and apply on your own at no cost.

Frequently asked questions
How many work credits do I need for SSDI?
It depends on your age when your disability began. Many people age 31 or older need at least 20 credits in the prior 10 years, plus enough total credits for their age. Younger workers often need fewer. Check your Statement for your own record.
Can I earn more than four credits in a year?
No. In general, four is the maximum in one year, even if you earn more than the amount needed for four credits.
Do credits expire?
Credits stay on your earnings record. For SSDI, though, the recent work test can stop being met after you leave covered work. That is the "date last insured" idea in plain words.
What if I was self-employed?
Self-employment can still earn credits when you report net earnings and pay Social Security taxes. Special rules can apply at low levels of net earnings. Your tax returns matter for those years.
What if I do not have enough credits for SSDI?
You may still want to learn about SSI, which is need-based. See SSDI vs SSI. You can also confirm your earnings record in case credits are missing.
