What Work Credits Are and How You Earn Them

Work credits are units of work history that Social Security uses to measure whether you have worked enough to be insured for disability benefits. You earn them by paying Social Security taxes on your wages or self-employment income. One work credit is earned for every $1,550 of wages or self-employment income you report in a calendar year (this dollar amount changes each year, so the threshold varies). You can earn a maximum of four work credits per year, no matter how much you earn above that threshold.

The amount you earn does not have to come all at once. If you earn $6,200 in a year, you will earn four credits that year. If you earn $1,550 in one month and nothing else that year, you will earn one credit. The credits accumulate in your Social Security record and stay there permanently — you do not lose them if you stop working.

Work credits are different from the amount of money you have earned. Social Security is not measuring your income level; it is measuring whether you have a consistent work history. A person who earned $10,000 in one year and a person who earned $100,000 in that same year both earn the same four credits.

Key Takeaways

  • You earn one work credit for every $1,550 of wages or self-employment income reported to Social Security in a calendar year, up to four credits per year.
  • The dollar amount required per credit changes annually, so you should check the current year's threshold on the Social Security website.
  • Most people explore for SSDI need 40 work credits total, with at least 20 earned in the 10 years before they become disabled.
  • Work credits do not expire once earned — they remain on your record even if you stop working for years.
  • If you became disabled before age 24, you may need fewer credits than someone who became disabled at 35 or older.

How Many Credits You Need for SSDI

The number of work credits required depends on your age when your disability begins. Social Security uses a formula based on the assumption that most people work steadily from their early twenties onward.

If you are age 31 or older when you become disabled, you generally need 40 work credits total, with at least 20 of those credits earned in the 10 years when ready before your disability began. This is the most common requirement. The 20 credits in the last 10 years rule means you must have worked roughly five of the past ten years — not necessarily consecutive, but spread across that decade.

If you became disabled between ages 24 and 30, you need 20 work credits total, with half of them earned in the years after you turned 21 and before your disability began. If you became disabled before age 24, you need only six work credits earned in the three years before your disability began. Blindness has its own rules: if you are blind, you need 40 credits total but no requirement that they be recent.

Checking Your Work Credit Record

Your work credits are recorded in your Social Security account. You can view them by creating a my Social Security account at ssa.gov, signing in, and selecting "Earnings Record." The page will show you the wages or self-employment income reported for each year and the number of credits you earned that year.

Check this record before you file for SSDI. If you see missing years, incorrect amounts, or years where you know you worked but no credits appear, contact Social Security to correct your record. Corrections can take several months, so do this early. Bring your tax returns or W-2 forms as proof if Social Security disputes your earnings.

If you are self-employed, make sure you reported your net self-employment income on your tax returns. Social Security pulls your earnings from IRS records, so if you did not file taxes or underreported income, those years will not count toward your credits.

Work Credits and Recent Work Requirements

Having 40 work credits is not enough on its own if you are over 31. Social Security also requires that at least 20 of those 40 credits were earned in the 10 years before your disability began. This rule exists because Social Security wants to may support you have a recent connection to the workforce.

The 10-year window is measured from the month your disability began. If you became disabled in March 2024, the 10-year window runs from March 2014 to March 2024. You need 20 credits earned somewhere in that span. You do not need to have earned them consecutively or in any particular pattern — they just need to fall within those 10 years.

If you have 40 credits but fewer than 20 were earned in the past 10 years, you will not meet the requirement. For example, if you worked steadily from 1995 to 2005 and earned 40 credits, but have not worked since 2005, and you become disabled in 2024, you do not have enough recent credits. The 20 credits you need must be recent enough to show you were still attached to the workforce.

What Happens If You Do Not Have Enough Credits

If you do not have enough work credits when you file for SSDI, Social Security will deny your claim based on insured status. This is different from a medical denial — it means you have not worked long enough, not that your condition is not severe enough.

You can reapply once you have earned more credits. If you are still working and can earn additional credits, you may become insured in the future. Social Security will tell you in the denial letter how many more credits you need and by what date you could earn them if you continue working.

If you cannot work and do not have enough SSDI credits, you may be able to file for Supplemental Security Income (SSI) instead. SSI is a needs-based program that does not require work credits — it requires only that your income and resources fall below certain limits. SSI has different rules and typically pays less than SSDI, but it is an option if you are disabled and have limited work history.

How Work Credits Change Year to Year

The dollar amount needed to earn one work credit is adjusted each year based on changes in average wages. In 2024, you need $1,550 in earnings to earn one credit. In 2023, the amount was $1,470. In 2022, it was $1,510. Social Security announces the new amount each October for the following year.

This means the threshold for earning credits goes up most years, but not every year. If you are working and tracking your progress toward SSDI, check the current year's amount on ssa.gov to know how much you need to earn to reach four credits that year. The amount does not affect credits you have already earned — those are locked in at the rate that applied when you earned them.

Frequently Asked Questions

Can I earn work credits while receiving unemployment benefits?

No. Work credits require wages paid to you by an employer or net income from self-employment. Unemployment benefits do not count as earnings for Social Security purposes. You must be actively working or self-employed to earn credits.

Do volunteer work or unpaid caregiving count toward work credits?

No. Only wages reported to Social Security or self-employment income reported on your tax return count. Volunteer work, caring for family members, or other unpaid work does not generate work credits, even if it is full-time.

What if I worked in another country before moving to the United States?

Work you did in another country generally does not count toward U.S. Social Security credits. However, some countries have agreements with the United States that allow work history to be combined. Contact Social Security to ask whether your country has a totalization agreement.

If I have enough credits now, can I stop working without losing them?

Yes. Credits do not expire or disappear. Once you have earned 40 credits, they remain on your record permanently. However, if you become disabled before age 31, you may need recent credits, so stopping work could affect whether you meet the recency requirement.

How do I know if my employer reported my wages correctly to Social Security?

Check your my Social Security account earnings record. It should match your W-2 forms. If there is a discrepancy, contact Social Security with your W-2 as proof. Corrections can take several months, so report errors as soon as you notice them.
