A fair number of the people who call our office open with some version of: I do not think I worked enough to get anything. They are sick, they are out of options, and they have talked themselves out of applying before anyone looked at their earnings record.
Sometimes they are right. Often they are not, and the reason is that the rule is not the one most people picture. Social Security Disability Insurance (SSDI) is an insurance program you paid premiums into through payroll taxes, and whether you are covered comes down to work credits. Here is how they actually work, how many you need at your age, and what to do if the answer is that you do not have enough.
What a work credit is
A work credit, called a quarter of coverage in Social Security Administration (SSA) documents, is the unit SSA uses to measure whether you have worked recently and long enough to be insured. In 2026 you earn one credit for every $1,890 in covered earnings, up to a maximum of four credits a year, which you hit at $7,560.
Two things surprise people here. First, the timing does not matter. Despite the old name, credits have not been tied to calendar quarters since 1978. If you earned the entire $7,560 in a single month of seasonal work and nothing the rest of the year, you still get all four credits for that year. Second, credits have nothing to do with the size of your check. Your monthly benefit is calculated from your lifetime average earnings. Credits only answer a yes-or-no question: are you insured?
The threshold moves each year with average wages. It was $1,810 in 2025 and $1,890 in 2026.
The two tests you have to pass
SSDI applies two separate tests, and both must pass before anyone reads a single medical record.
The duration of work test asks whether you have worked long enough over your lifetime. For most adults disabled at 31 or older, that means 40 credits, which is ten years of covered work.
The recent work test asks whether you worked recently enough. For most adults 31 and older, the rule of thumb is 20 credits earned in the ten years before your disability began, which is five of the last ten years. This is the test that surprises people, and it is the one that quietly ends claims from workers who stopped years before applying.
Younger workers need far fewer credits
Nobody expects a 26-year-old to have a decade of work behind them, and the rules reflect that. The requirements slide down with age:
- Before age 24: generally 6 credits earned in the three years before your disability began. That is roughly a year and a half of work.
- Ages 24 through 30: generally credits for half the time between age 21 and when your disability began. Disabled at 27, for example, that is three years of work out of the six-year span.
- Age 31 and older: at least 20 credits in the last ten years, rising with age toward 40 credits total.
If you are in your twenties and assumed SSDI was out of reach, check before you conclude that. Younger claimants qualify more often than they expect.
Date last insured: the deadline nobody tells you about
Because of the recent work test, your SSDI coverage expires after you stop working. That expiration has a name: the date last insured, or DLI. Roughly speaking, coverage runs about five years past the end of your covered work.
This matters enormously, and here is the version that trips people up. To win SSDI, you do not have to prove you are disabled today. You have to prove you became disabled before your date last insured. Someone who stopped working in 2019 with a DLI of December 2024, applying today in 2026, must show the disability began on or before that 2024 date, using medical records from back then. We take these cases regularly, and the work is archaeological: pulling old treatment records, hospital charts, and statements that establish how bad things were during the insured window.
If you have been out of work for years and are only now considering a claim, the honest advice is to stop reading and go check your DLI. Every month of delay makes the proof harder.
A worked example
Take a 44-year-old Colorado warehouse worker who becomes disabled in 2026. He worked steadily from 2004 to 2021, then stopped. Over 17 years of full-time work he banked the maximum four credits a year, well past the 40 he needs, so the duration test is satisfied comfortably.
The recent work test is the problem. Looking back ten years from 2026 to 2016, he worked 2016 through 2021, which is six years at four credits each, or 24 credits. He needs 20. He passes, with four to spare. Now change one fact: if he had stopped in 2019 instead, he would have 2016 through 2019, or 16 credits, and he would fail the recent work test as of 2026. Same career, same illness, different answer, entirely because of when the work ended. That is why the DLI question comes first in every consultation.
How to check your own record in ten minutes
Do not guess at this. Create or log into your my Social Security account at ssa.gov and open your Social Security Statement. It lists your earnings year by year, tells you how many credits you have, and states plainly whether you currently meet the requirements for disability benefits.
While you are in there, read the earnings history line by line. Missing years happen more often than people expect, especially after a name change, with self-employment income, or when an employer misreported wages. A missing year can be the difference between insured and not, and SSA will correct errors when you bring documentation. Old W-2s and tax returns are the fix.
If you do not have enough credits
This is not the end of the conversation, and it is where a lot of people give up too early. Supplemental Security Income (SSI) is the needs-based program, funded by general revenue, and it requires no work credits at all. Eligibility turns on income and resources instead: in 2026 the federal payment is $994 a month with countable resources under $2,000 for an individual. Someone who fails every work-credit test can still be approved for SSI on the identical medical standard. Our plain-English guide to SSDI versus SSI lays out which one fits your situation.
Two other doors worth knowing. If you are an adult whose disability began before age 22 and a parent is receiving Social Security or has died, you may qualify on a parent’s record through Disabled Adult Child benefits, again with no work history of your own; our parent’s guide to SSI and DAC covers it. And disabled widows and widowers can sometimes claim on a late spouse’s record. Families sorting through these options will find the rest of our material for them in the caregiver hub.
Working while you apply
Counterintuitively, earning a little can help and a lot can hurt. Work in 2026 that grosses $1,690 or more a month generally counts as substantial gainful activity and stops a claim at step one of the five-step process, regardless of your credits. Below that line, part-time work is permitted and still earns credits toward future coverage. If you are considering a return to work while a claim is pending, talk to your representative first; short attempts that fail because of the illness can often be treated as unsuccessful work attempts rather than evidence you can work.
The Colorado angle
Two patterns come up constantly in our Colorado caseload. The first is seasonal and construction work, where earnings are compressed into part of the year. Good news: because credits depend on annual totals rather than monthly consistency, a strong summer on a Front Range job site can bank all four credits for the year. The second is self-employment, which is common among ranchers, contractors, and gig workers on the Western Slope. Self-employed people earn credits the same way, at $1,890 per credit, but only on net earnings actually reported and taxed. Years of underreporting to reduce a tax bill translate directly into missing credits, and that bill comes due at exactly the wrong moment.
If the record needs correcting, the Denver SSA field office and the other Colorado offices handle earnings corrections, and the initial application is where the insured-status question gets settled for good.
Quick answers
Do credits expire? The credits themselves stay on your record permanently. Your insured status for disability does expire, which is the date last insured problem above.
Does military service count? Yes, and service members may receive additional wage credits for certain periods. Bring your service dates to the consultation.
Do more credits mean a bigger check? No. Beyond the number needed to qualify, extra credits change nothing. The benefit amount comes from your lifetime earnings average.
I worked under the table for years. Does any of it count? Only earnings on which Social Security taxes were paid. It is a painful answer, and it is why the SSI and DAC paths matter so much for people in that situation.
Find out where you stand before you rule yourself out
Insured status is a yes-or-no question with a checkable answer, and it takes us about five minutes on a free call. If you are in Denver, on the Front Range, or anywhere in Colorado and you have been assuming you did not work enough to qualify, let us look before you decide.
