What Work Credits Are and How They Count Toward SSDI

A work credit is a record of earnings that Social Security uses to measure whether you have worked enough to may have access to for SSDI. You earn one work credit for every $1,550 of wages or self-employment income you report in a calendar year (the dollar amount changes each year—it was $1,550 in 2024). You can earn a maximum of four work credits per year, regardless of how much you earn.

Social Security does not count the total amount you have earned over your lifetime. Instead, it counts how many years you have worked and reported income. The system is designed to measure whether you have been in the workforce recently enough and long enough to may have access to. Most people need 40 work credits total to may have access to for SSDI, with at least 20 of those credits earned in the 10 years before you become disabled.

The reason Social Security uses this system is to may support that SSDI goes to people who have a genuine work history, not to people who have never worked or who worked only briefly decades ago. The "recent work" requirement—those 20 credits in 10 years—also reflects the program's purpose: to replace income for people who were actively working when they became unable to work.

Key Takeaways

  • You earn one work credit for every $1,550 of reported wages or self-employment income in a calendar year, up to four credits per year.
  • Most SSDI applicants need 40 total work credits, with at least 20 earned in the 10 years before the onset of disability.
  • Work credits are based on income you report to Social Security, not on hours worked or the type of job you held.
  • You can check your work credit record by creating a my Social Security account and viewing your Statement of Earnings.
  • If you do not have enough work credits, you may still may have access to for Supplemental Security Income (SSI) based on financial need rather than work history.

The Annual Dollar Threshold and How It Changes

Each January, Social Security announces the dollar amount needed to earn one work credit for that year. In 2024, that amount is $1,550. In 2023, it was $1,510. In 2022, it was $1,470. The threshold rises most years because it is tied to the national average wage index.

This means that if you earned $1,550 or more in 2024, you have earned at least one work credit for that year. If you earned $3,100, you have earned two credits. If you earned $6,200, you have earned four credits. If you earned $10,000, you still have only four credits—the maximum for one year.

The dollar threshold applies to reported income only. If you were paid in cash and did not report it to Social Security, it does not count toward work credits. Self-employment income counts, but only if you report it on your tax return and pay self-employment tax. This is why Social Security can verify your work credits by looking at your tax records.

How to Read Your Work Credit Record

Your work credit history is recorded on your Statement of Earnings, which Social Security maintains in your file. You can view this statement by creating a free account at my Social Security (ssa.gov/myaccount). Once you log in, you can see how many work credits you have earned in each year since you began working.

The statement shows the year, the amount of wages or self-employment income you reported, and the number of work credits you earned that year. If you see a year with no income listed, Social Security has no record of you working that year. If you know you worked but Social Security shows no record, you may need to contact Social Security with documentation—a W-2, tax return, or pay stubs—to correct the record.

Errors on your Statement of Earnings can affect your SSDI decision. If you spot a year where your income is listed as lower than it actually was, or a year that is missing entirely, report it to Social Security before you file for SSDI. Correcting the record takes time, and you want it accurate before your claim is reviewed.

Work Credits for People Who Became Disabled Before Age 31

If you became disabled before age 31, Social Security uses a different rule. You do not need 40 total work credits. Instead, you need 20 work credits earned in the 10 years before your disability began. This rule recognizes that younger workers have not had time to accumulate 40 credits.

For example, if you became disabled at age 28, Social Security will look at the 10 years from age 18 to 28 and count how many work credits you earned in that period. If you have at least 20, you meet the work credit requirement. If you have fewer than 20, you do not may have access to for SSDI based on your own work record (though you might may have access to for benefits as a family member of someone else who receives Social Security).

This rule is one reason why younger applicants sometimes have an easier time meeting the work credit requirement than older applicants who have gaps in their work history. A 28-year-old with 20 credits in 10 years meets the standard. A 55-year-old with 20 credits in 10 years does not, because they need 40 total.

What Happens If You Do Not Have Enough Work Credits

If you do not have enough work credits to may have access to for SSDI, you may still have other options. The most common alternative is Supplemental Security Income (SSI), which is a needs-based program. SSI does not require work credits. Instead, it looks at your current income and assets. If you have little income and few assets, you may may have access to for SSI even if you have never worked or worked only briefly.

Another option is to may have access to for benefits as a family member. If your spouse, parent, or adult child receives Social Security retirement or disability benefits, you may be able to receive benefits on their work record instead of your own. This is called a "family benefit" or "auxiliary benefit." You would need to meet other requirements—such as age or disability status—but you would not need your own work credits.

If you are close to having enough work credits, you might also consider whether continuing to work is an option. If you can work part-time or in a limited capacity, earning income for another year or two could give you the credits you need. Social Security has work incentive programs that allow you to test your ability to work without when ready losing benefits, which is covered in detail in other resources on this site.

How Self-Employment Income Counts Toward Work Credits

If you are self-employed, your work credits are based on your net self-employment income—the amount you report on your tax return after business expenses. You do not earn credits based on gross revenue. A self-employed person who grosses $50,000 but has $48,000 in expenses has only $2,000 in net income, which would earn one work credit in 2024 (since $2,000 exceeds the $1,550 threshold).

You must also pay self-employment tax on your net income for it to count. If you report self-employment income on your tax return but do not pay self-employment tax, Social Security may not count it toward work credits. This is one reason why it is important to file a complete tax return each year, even if you owe little or no income tax.

If you have been self-employed for many years but did not file tax returns for some of those years, those years will not count toward your work credits. Correcting this after the fact is difficult. If you are self-employed and plan to explore for SSDI, make sure your tax records are complete and accurate before you file your claim.

Checking Your Work Credits Before You explore

The best time to check your work credit record is before you file for SSDI. This gives you time to correct any errors and to understand whether you meet the work credit requirement. If you do not have enough credits, you can explore SSI or family benefits before you invest time in an SSDI process.

To check your record, create a my Social Security account and request your Statement of Earnings. Review it carefully for each year you worked. If you see missing years or years with income that seems too low, gather your documentation—W-2s, tax returns, pay stubs—and contact Social Security to request a correction. Social Security can usually correct records if you provide evidence, but the process takes several weeks.

If you are unable to create an online account 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 Statement of Earnings to be mailed to you. You can also visit a local Social Security office in person. Having your work credit record in hand before you explore makes the SSDI process clearer and faster.

Frequently Asked Questions

Can I earn work credits after I become disabled?

No. Work credits are based on income you earned before your disability began. Once Social Security determines that you became disabled on a specific date, only income earned before that date counts. If you continue to work after becoming disabled, that income does not add to your work credit total for SSDI purposes, though it may affect your benefits under work incentive rules.

Do I need to have worked every year to get 40 work credits?

No. You can earn four credits per year, so you need only 10 years of work to accumulate 40 credits. You do not need to have worked every year. You could have worked 10 years and been out of the workforce for 20 years and still have enough credits, as long as you meet the "recent work" requirement of 20 credits in the 10 years before disability.

What if my Statement of Earnings shows income I did not report?

Contact Social Security when ready to dispute the error. Bring documentation such as W-2s or tax returns. If the income is incorrect, Social Security will correct it. If the income is correct but you did not report it, you may owe back taxes, but correcting your Social Security record is still important for your SSDI claim.

Do military service years count as work credits?

Military service does not automatically create work credits. However, if you received wages during military service, those wages count toward work credits the same way civilian wages do. Some military service members also receive deemed wage credits for certain periods, but this is rare and applies only to specific service dates. Ask Social Security about your specific service record.

Can I get work credits for unpaid work like volunteering or caregiving?

No. Work credits are based only on reported income. Volunteer work, caregiving for family members, or other unpaid work does not generate work credits, even if it was full-time and demanding. Only wages or self-employment income that you report to Social Security counts.
