What "Do Disability" means in the context of work credits

Do Disability is the term Social Security uses to describe the rules that decide whether your work history qualifies you for SSDI (Social Security Disability Insurance). It is not a separate program or a thing you do—it is the calculation Social Security runs to see if you have earned enough work credits to be insured for disability benefits.

When you work and pay Social Security taxes, you earn credits toward SSDI coverage. The "Do Disability" rules tell you how many credits you need, how recent those credits must be, and what happens if you do not have enough. Understanding these rules matters because they determine whether you can even explore for SSDI, regardless of how severe your condition is.

The rules are straightforward but strict. You cannot get SSDI without meeting the work credit requirement first. This is different from SSI (Supplemental Security Income), which does not require work credits at all—only income and asset limits.

Key Takeaways

  • You need 40 work credits total to be insured for SSDI, with at least 20 of those credits earned in the 10 years before you became disabled.
  • You earn one work credit for every $1,550 of wages you earn in a year (the dollar amount changes each year, so the exact figure varies).
  • If you do not have enough credits, you cannot receive SSDI no matter how disabled you are, but you may be able to receive SSI instead.
  • Social Security checks your work record automatically when you explore, so you do not have to calculate your credits yourself.
  • If you worked outside the United States, some of that work may count toward your credits under agreements Social Security has with other countries.

How many work credits you need

The standard requirement is 40 work credits total, with at least 20 of those credits earned in the 10 years before you became disabled. This second rule is sometimes called the "recent work" requirement, and it is the one that trips up people who worked steadily years ago but have not worked recently.

If you became disabled in 2024, for example, you need at least 20 credits earned between 2014 and 2024. Credits you earned before 2014 count toward your total of 40, but they do not count toward the "recent work" part. This means you could have 30 credits from the 1990s and 10 credits from 2020–2024, and you would not meet the requirement—you would need 20 from that recent 10-year window.

There is one exception: if you became disabled before age 24, you need only 6 credits earned in the 3 years before you became disabled. This rule exists because young people have not had time to build a full work history.

How you earn work credits

You earn work credits by earning wages and paying Social Security taxes. In 2024, you earn one credit for every $1,550 you earn in a year. You can earn a maximum of 4 credits per year, which means you need to earn at least $6,200 in a year to max out your credits for that year.

The dollar amount that triggers each credit changes every year because it is tied to the national average wage. In 2023, it was $1,470 per credit. In 2022, it was $1,365. Social Security publishes the current year's amount on their website each October.

Self-employment income counts the same way as wages, as long as you pay self-employment tax. Work you do "under the table" or without paying taxes does not count, because Social Security has no record of it.

What happens if you do not have enough credits

If you do not meet the work credit requirement, Social Security will deny your SSDI process. The denial letter will tell you exactly how many credits you have and how many you need. This is not a temporary setback—you cannot receive SSDI without meeting this requirement.

However, you may have other options. If you do not have enough work credits but you have very low income and few assets, you may be able to receive SSI (Supplemental Security Income) instead. SSI does not require work credits. It is a needs-based program, meaning it looks at your income and assets, not your work history. The monthly payment is usually smaller than SSDI, and the rules are stricter about how much money you can have, but it is available to people who do not may have access to for SSDI.

You can explore for both SSDI and SSI at the same time. Social Security will evaluate you for both programs and tell you which one you may have access to for, if any.

How Social Security verifies your work credits

You do not have to count your credits yourself. When you explore for SSDI, Social Security pulls your earnings record from their database. This record is built from the W-2 forms your employers send in and from self-employment tax returns you file.

Social Security compares your earnings record against the work credit requirement and tells you in writing whether you meet it. If there is a mistake—if an employer reported your wages under the wrong name or Social Security number, for example—you can dispute it by contacting Social Security with proof of the correct information.

You can also check your own earnings record before you explore by creating a my Social Security account on the Social Security website. Your statement shows every year of earnings Social Security has on file and how many credits you have earned so far. This is useful if you want to know where you stand before you explore.

Work credits and international employment

If you worked in another country, some of that work may count toward your SSDI credits. Social Security has totalization agreements with about 30 countries. These agreements let you combine work credits from the United States with work credits from the other country to meet the requirement.

The countries with totalization agreements include Canada, the United Kingdom, France, Germany, Italy, Japan, South Korea, and many others. If you worked in one of these countries and paid into their social security system, you can ask Social Security to count that work toward your SSDI requirement.

To use a totalization agreement, you will need to provide proof of your work and contributions in the other country. This usually means getting a statement from that country's social security agency. The process takes longer than a standard SSDI process, so plan for extra time if you are using work from another country.

What "Do Disability" does not cover

Meeting the work credit requirement is only the first step. Having enough credits means you are insured for SSDI—you are allowed to explore. It does not mean you will be approved. Social Security will still evaluate whether your condition is severe enough to prevent you from working, whether it is expected to last at least 12 months, and whether it meets the medical criteria in their rules.

Many people meet the work credit requirement but are denied SSDI because their condition does not meet Social Security's definition of disability. The "Do Disability" rules only answer the question "Are you insured?" They do not answer "Are you disabled?"

Frequently Asked Questions

Can I get SSDI if I have not worked in 15 years?

Not if you became disabled after those 15 years. You need at least 20 credits earned in the 10 years before you became disabled. If you became disabled in 2024 and your last work was in 2009, you do not meet the recent work requirement. You may be able to receive SSI instead if your income and assets are low enough.

Do credits expire if I stop working?

No. Credits you earned stay on your record forever. However, the "recent work" requirement means you need to have earned credits recently enough. If you earned 40 credits but none in the last 10 years, you are not insured for SSDI.

If I work part-time, how long will it take me to earn 40 credits?

You can earn a maximum of 4 credits per year, so it takes a minimum of 10 years to earn 40 credits. If you earn less than $6,200 per year, it will take longer. The exact timeline depends on how much you earn each year.

What if Social Security has the wrong earnings on my record?

You can dispute it by contacting Social Security with proof of your correct earnings, such as W-2 forms or tax returns. You have a limited time to correct errors, so contact them as soon as you notice a mistake. You can also see your earnings record for free on my Social Security.

Do I need to be a U.S. citizen to earn work credits?

No. You can earn work credits if you have a valid Social Security number and work legally in the United States, regardless of citizenship status. However, citizenship or immigration status may affect whether you can receive benefits once you are approved for SSDI.
