The Work Credit Timeline for SSDI

Social Security Disability Insurance requires you to have worked long enough and recently enough to build up work credits. The number of years that matters is not how long you worked total, but how many credits you earned in the years just before you became disabled. Most people need 40 credits, with at least 20 of them earned in the 10 years before disability began.

A work credit is earned by paying Social Security taxes on your wages. In 2024, you earn one credit for each $1,730 of wages you make (this amount changes yearly). You can earn up to four credits per year, which means you can build your full 40-credit requirement in as little as 10 years of work. But the timing matters as much as the total.

If you became disabled at age 24, you might need only 6 credits total, with 3 earned in the 3 years before disability. If you became disabled at age 31, you would need 20 credits, with 10 earned in the 10 years before disability. The younger you are when disability begins, the fewer credits you need — but you still need to have earned them recently.

Key Takeaways

  • Most SSDI applicants need 40 work credits total, with at least 20 earned in the 10 years before disability began.
  • You earn one credit per $1,730 of wages in 2024 (the amount adjusts yearly), and you can earn up to four credits per year.
  • The younger you are when you become disabled, the fewer total credits you need, but you still must have earned them within a recent time window.
  • Work credits are based on wages you paid Social Security taxes on — self-employment income, cash work, and informal jobs do not count.
  • Social Security keeps a record of your earnings history; you can view your work credits on your my Social Security account online.

How Work Credits Connect to Your Age at Disability

Social Security uses a sliding scale. The older you are when disability begins, the more credits you need. Here is how it breaks down:

If you became disabled between ages 24 and 30, you need 6 credits, with 3 earned in the 3 years before disability. At age 31, you need 8 credits with 4 in the past 2 years. By age 38, you need 16 credits with 8 in the past 5 years. At age 42 and older, you need the full 40 credits with 20 in the past 10 years. The rule is designed so that younger workers do not lose coverage if they become disabled early, but older workers have had more time to build credits and are expected to have done so.

This matters because it means a 26-year-old with only 8 work credits might still may have access to for SSDI if they became disabled today, while a 45-year-old with 8 credits would not. The same work history produces different outcomes depending on when the disability began.

What Counts as a Work Credit and What Does Not

A work credit is earned only when you pay Social Security taxes on your income. If you work for an employer who withholds Social Security tax from your paycheck, those wages count. If you are self-employed and pay self-employment tax, that counts too. But cash payments, informal work, and jobs where no Social Security tax was paid do not count toward credits, even if you worked full-time.

This is why some people who have worked for many years still do not have enough credits. A person who worked off-the-books for 15 years, or who worked only for employers who did not withhold Social Security tax, would have zero credits. Conversely, someone who worked part-time at a regular job for 10 years and paid taxes would have the full 40 credits.

Social Security has a record of every credit you have earned. You can see your work history and credit count by creating an account on my Social Security (ssa.gov) and viewing your Social Security Statement. This statement shows your earnings year by year and the credits you earned in each year.

The Recent Work Requirement and Why It Exists

Even if you have 40 credits, you must have earned at least 20 of them in the 10 years before your disability began. This is called the recency requirement. The rule exists because Social Security assumes that if you have not worked recently, you may not actually be disabled — you may straightforward have left the workforce for other reasons.

For example, someone who worked steadily from age 18 to 35, then stopped working and did not work again, would have 40 credits but would not meet the recency requirement if they applied for SSDI at age 50. They would need to have earned 20 of those 40 credits between ages 40 and 50. If they only earned credits between ages 18 and 35, they would not may have access to, even though they worked for 17 years.

There is one exception: if you are blind, you do not have to meet the recency requirement. You need only 40 credits total, earned at any point in your life. This is the only SSDI rule that does not require recent work.

How to Check Your Work Credit Record

Social Security maintains an earnings record for every person with a Social Security number. You can view your record online through my Social Security, which is free and does not require you to call or visit an office. To access it, go to ssa.gov, click "Create my Social Security account," and follow the steps to verify your identity. Once you are logged in, you can see your earnings history and the number of credits you have earned in each year.

If you see an error — a year where you worked but no earnings are recorded, or earnings that are too low — you can request a correction. You will need to provide documents like W-2 forms, pay stubs, or tax returns that show the correct earnings. Social Security has a time limit for correcting errors, usually three years, three months, and 15 days after the year in which the earnings were supposed to be recorded.

If you do not have online access or prefer to speak with someone, you can call Social Security at 1-800-772-1213 (TTY 1-800-325-0778) and ask for a copy of your Social Security Statement. They will mail it to you, and it will show your earnings history and work credits.

What Happens If You Do Not Have Enough Credits

If you do not have enough work credits when you explore for SSDI, Social Security will deny your claim. The denial will state how many credits you have and how many you need. You cannot appeal based on the work credit requirement itself — it is a rule, not a judgment call. But you can reapply later if you return to work and earn more credits.

Some people who do not have enough SSDI credits may be able to receive Supplemental Security Income (SSI) instead. SSI is a needs-based program that does not require work credits. It is based on your current income and resources, not your work history. If your household income and assets are below the limit (which varies by state), you may may have access to for SSI even if you have zero work credits. SSI payments are typically lower than SSDI, and the rules are stricter, but it is an option if you do not meet the work credit requirement.

How Earnings Affect Your Credits After You Start Receiving SSDI

Once you are approved for SSDI, the work credits you earned in the past do not change. But if you return to work while receiving SSDI, your benefits may be affected by the Substantial Gainful Activity (SGA) limit. In 2024, SGA is $1,550 per month for non-blind beneficiaries. If you earn more than that, Social Security may determine that you are no longer disabled and stop your benefits.

However, SSDI has work incentives that allow you to test your ability to work without when ready losing benefits. The Trial Work Period lets you earn any amount for nine months without affecting your benefits. After that, there is a Continued Medicaid Coverage period and other programs like Impairment Related Work Expenses (IRWE) and Plan to Achieve Self-Support (PASS) that can help you keep working and keep some or all of your benefits. These are separate from the work credit rules, but they matter if you are thinking about returning to work after you start receiving SSDI.

Frequently Asked Questions

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

It depends on your age and how many credits you earned before you stopped working. If you are under 42 and have enough credits for your age, you may may have access to even if you have not worked recently. But if you are 42 or older, you need 20 of your 40 credits to have been earned in the past 10 years. If you have not worked in five years, you would need all 20 of those recent credits to have been earned in the five years before that.

Do credits expire if I do not use them?

No, work credits do not expire. Once you earn a credit, it stays on your record forever. But the recency requirement means that for most ages, you need to have earned credits recently. The credits you earned 20 years ago still count toward your total of 40, but they do not satisfy the requirement that 20 credits be earned in the past 10 years.

What if I worked for a government agency that does not pay into Social Security?

Some federal, state, and local government employees do not pay Social Security tax. If you worked for one of these employers, those years do not count toward SSDI credits. However, if you also worked for a private employer or a government employer that does pay Social Security tax, those years do count. You can see which employers withheld Social Security tax by checking your earnings record on my Social Security.

Can I count credits from work I did outside the United States?

Generally, no. Social Security credits are based on wages you earned in the United States and paid U.S. Social Security tax on. Work you did in another country does not count, even if you paid taxes there. However, some countries have agreements with the United States that allow work in those countries to count toward Social Security credits. You would need to contact Social Security directly to learn about your country has such an agreement.

If I am denied for SSDI because of work credits, can I appeal?

You can appeal the denial, but the appeal cannot change the work credit requirement itself. If Social Security determines you do not have enough credits, the only way to overturn that is to show that Social Security made an error in counting your credits or calculating your earnings. If your credits are correct, the denial stands. Your option is to reapply later if you earn more credits, or to explore whether you may have access to for SSI instead.
