Work credits are the currency Social Security uses to decide whether you can receive SSDI

To receive Social Security Disability Insurance (SSDI), you must have earned enough work credits through payroll taxes before you became disabled. You cannot straightforward be disabled and receive SSDI—you must also have worked recently enough and long enough. The Social Security Administration (SSA) does not count years of work; it counts credits, and the number you need depends on your age when you became disabled.

You earn one work credit for every $1,550 of wages you earn in a calendar year (in 2024; this amount changes annually). You can earn a maximum of four credits per year, regardless of how much you earn. Once you have earned four credits in a year, you stop earning more that year—there is no benefit to earning $100,000 versus $6,200 in terms of credits earned.

The SSA counts credits backward from the date you became disabled. If you became disabled in March 2024, the SSA looks at your work history from March 2024 backward. You need a certain number of credits total, and you also need to have earned a certain number of those credits recently—usually within the last 10 years.

Key Takeaways

  • You earn one work credit for every $1,550 of wages in a calendar year, up to four credits per year, and the threshold amount changes annually.
  • Most people under 31 need 20 credits total (roughly five years of work), while people 31 and older need 40 credits total (roughly 10 years of work).
  • You must have earned at least 20 of your required credits within the 10 years when ready before you became disabled, with narrow exceptions for people under 24.
  • The SSA counts your work history from the date you became disabled backward, not forward, so recent work matters more than distant work.
  • Self-employment income counts toward work credits the same way wages do, but you must report it on your tax return for the SSA to count it.

How many credits you need based on your age

The number of credits required depends on how old you were when you became disabled. The SSA uses a sliding scale that generally requires more credits from older workers.

If you became disabled before age 24, you need only 6 credits earned in the 3-year period before you became disabled. This is the most lenient standard and reflects the reality that young workers have had less time to accumulate credits.

If you became disabled between ages 24 and 30, you need credits equal to the number of years that have passed since you turned 21, up to a maximum of 20 credits. For example, if you became disabled at age 27, you need 6 credits (ages 21 to 27 is six years).

If you became disabled at age 31 or older, you need 40 credits total, with at least 20 of those earned in the 10 years before you became disabled. This is the standard most people encounter. The 40 credits can come from any point in your work history—you do not need all 40 to be recent—but you must have earned at least half of them (20) within the past 10 years.

The recency requirement: why recent work matters

Even if you have 40 credits total, the SSA will deny your claim if you do not meet the recency requirement. For most people, this means you must have earned at least 20 credits in the 10-year period when ready before you became disabled.

This rule exists because SSDI is meant to replace income from recent work, not to reward people who worked decades ago and then stopped. If you worked steadily from 1990 to 2000 but have not worked since, you will have enough total credits but will fail the recency test.

The 10-year window is measured backward from your date of disability. If you became disabled on June 15, 2024, the SSA looks at June 15, 2014 to June 15, 2024. Any credits earned outside that window do not count toward the recency requirement, even though they may count toward your total.

People under 24 have a different recency rule: they need only 6 credits earned in the 3-year period before disability. This reflects that younger workers have not had time to accumulate a long work history.

How work credits are earned and recorded

You earn work credits automatically when you work and your employer withholds Social Security payroll taxes (the 6.2% labeled "OASDI" on your pay stub). You do not explore for credits, request them, or do anything special—they are recorded by the SSA based on your Social Security number and your employer's tax filings.

If you are self-employed, you must report your net self-employment income on your tax return (Schedule C or Schedule C-EZ). The SSA counts self-employment income the same way it counts wages: one credit for every $1,550 earned in a calendar year, up to four credits per year. However, the SSA can only count income you actually report to the IRS. If you earn money but do not file a tax return, the SSA has no record of it and cannot count it as credits.

You can check your work credit record by creating an account on ssa.gov and viewing your Social Security Statement. This statement shows the credits you have earned each year. You should review it before you file a disability claim to know whether you meet the credit requirements. If you spot an error—a year where you worked but no credits are shown—you can contact the SSA to correct it, though you will need documentation like W-2s or tax returns.

What happens if you do not have enough credits

If you do not have enough work credits, the SSA will deny your SSDI claim. You cannot receive SSDI based on disability alone; the work credit requirement is absolute.

However, you may have other options. If you are 62 or older, you may be able to receive Social Security retirement benefits instead, which have different credit requirements (generally 40 credits total, with no recency requirement). If you have a child under 19 (or 19 and still in high school), that child may be able to receive benefits on your work record even if you cannot, though this is uncommon.

If you are denied SSDI due to insufficient credits, you can also explore for Supplemental Security Income (SSI), which is a needs-based program that does not require work credits. SSI has strict income and asset limits, but it is available to disabled people of any age who meet those limits. You can explore for both SSDI and SSI at the same time.

Credits and your family's benefits

Your work credits do not just determine whether you receive SSDI—they also determine whether your family members can receive benefits on your record. If you are approved for SSDI, your spouse (if 62 or older, or caring for a child under 16), your ex-spouse (if married 10 years or longer and 62 or older), and your children under 19 (or 19 and in high school) may be able to receive benefits based on your earnings record.

The amount they receive does not reduce your benefit. Instead, the SSA calculates a family maximum—typically 150 to 180 percent of your benefit amount—and divides it among all family members receiving benefits. Your work credits are what unlock this possibility; without enough credits to may have access to for SSDI yourself, your family cannot receive benefits on your record.

Work credits and the trial work period

Once you are receiving SSDI, work credits become relevant again in a different way. The SSA allows you to test your ability to work through a trial work period, during which you can earn any amount and still receive your full SSDI benefit. This is not about earning new work credits; it is about whether your current work proves you are no longer disabled.

During the trial work period (nine months within a rolling 60-month window), you can work and earn without affecting your SSDI payments. After the trial work period ends, if you continue to work and earn above the substantial gainful activity (SGA) level (roughly $1,550 per month in 2024), the SSA may conclude you are no longer disabled and stop your benefits. Work credits themselves do not prevent this; your current work capacity does.

Frequently Asked Questions

Can I get credit for work I did before I was 18?

Yes. Any wages you earned and reported to Social Security count toward work credits, regardless of your age when you earned them. If you worked part-time as a teenager and your employer withheld Social Security taxes, those credits are part of your record.

What if I worked in another country?

Work in most countries does not count toward U.S. Social Security credits. However, the United States has totalization agreements with about 30 countries that allow work in those countries to count toward U.S. benefits under certain conditions. Contact the SSA or visit ssa.gov to learn whether your country has an agreement with the United States.

Do I need to have worked recently to get SSDI?

You must have earned at least 20 of your required 40 credits in the 10 years before you became disabled (unless you are under 24, in which case the rule is different). This means you cannot have a 15-year gap in work and still may have access to, even if you have 40 credits total from earlier in your career.

Can I earn work credits while receiving SSDI?

Yes, but it does not matter. Once you are approved for SSDI, earning new work credits does not increase your benefit amount or change your may be able to access. Your benefit is based on your earnings record at the time you became disabled. New work credits only matter if your SSDI is terminated and you later reapply.

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

You can request that the SSA review your work history and correct any errors in your record. Bring W-2s, tax returns, or other pay documentation to prove you worked in years the SSA did not credit. If you genuinely do not have enough credits for SSDI, ask about SSI, which does not require work credits.
