What Work Credits Are and Why They Matter

Work credits are the measure Social Security uses to decide whether you have worked enough to receive SSDI. You earn them by paying Social Security taxes on your wages — one credit per quarter (three-month period) when you earn at least a set amount. The Social Security Administration does not count your total earnings; it counts how many quarters you worked and paid taxes.

The number of credits you need depends on your age when your disability begins. Younger workers need fewer credits than older workers. Once you have earned enough credits, you keep them — they do not expire. This means if you worked steadily for several years and then stopped, you may still have enough credits to may have access to for SSDI later, even if you have not worked recently.

Key Takeaways

  • You earn one work credit per quarter when you earn at least a minimum amount (which changes yearly); in 2024, that amount is $1,550 per quarter.
  • Most people need 40 credits total, with at least 20 earned in the 10 years before disability begins, but younger workers may need as few as 6 credits.
  • Work credits do not expire once earned, so past employment counts even if you have not worked recently.
  • Self-employment income counts toward work credits the same way wages do, as long as you report it and pay self-employment tax.
  • You can check your exact work credit record by creating a my Social Security account or requesting a Statement of Earnings from the Social Security Administration.

How Many Credits You Need Based on Your Age

The Social Security Administration uses a sliding scale. If you become disabled at age 31 or older, you typically need 40 credits, with at least 20 of those earned in the 10 years when ready before your disability began. This is the most common requirement.

If you become disabled before age 31, the requirement drops. At age 24, you need only 12 credits, with 6 earned in the 3 years before disability. At age 22, you need 12 credits with no time requirement. Before age 22, you need only 6 credits earned in the 3 years before disability. The younger you are, the fewer credits the Social Security Administration requires, because younger workers have had less time to build a work history.

Blind individuals have different rules: if you are blind and age 55 or older, you need only 20 credits, with at least 15 earned in the 20 years before disability. If you are blind and under 55, you follow the age-based scale above.

How to Earn Work Credits

You earn work credits automatically when you work and pay Social Security taxes on your wages. Your employer withholds Social Security tax from your paycheck. For 2024, you earn one credit for each $1,550 you earn in a quarter; this amount increases most years. You can earn a maximum of four credits per year, one per quarter, regardless of how much you earn.

If you are self-employed, you earn credits the same way, but you must report your net self-employment income on your tax return and pay self-employment tax. The Social Security Administration counts your net earnings (income minus business expenses) toward credits. You still earn a maximum of four credits per year.

Work credits are tied to the calendar year and quarters, not to when you actually receive payment. If you earn $1,550 in January through March (the first quarter), you earn one credit for that quarter, even if your employer pays you in April.

Checking Your Work Credit Record

The Social Security Administration maintains a record of your earnings and work credits. You can view this record yourself by creating a my Social Security account at ssa.gov. Once logged in, you can see your earnings history and the number of credits you have earned each year.

If you do not have an online account, you can request a Statement of Earnings by mail. Call the Social Security Administration at 1-800-772-1213 (TTY 1-800-325-0778) and ask them to mail you a statement, or visit your local Social Security office in person. The statement shows your earnings year by year and your total credits.

Review your record carefully. If you see missing earnings or credits that should be there, contact the Social Security Administration with your tax returns or W-2 forms as proof. Errors can be corrected, but it is easier to catch them before you file for SSDI.

Work Credits and Recent Work Requirements

Having enough total credits is only part of the requirement. If you are 31 or older, the Social Security Administration also requires that at least 20 of your 40 credits were earned in the 10 years before your disability began. This is called the "recency of work" requirement.

The 10-year window is measured from the date your disability is deemed to have started, not from the date you file. If you stopped working in 2015 and file for SSDI in 2024, your 10-year window runs from 2014 to 2024. Any credits you earned before 2014 do not count toward the recency requirement, even though they count toward your total of 40.

This rule exists because Social Security wants to may support that people receiving SSDI have been in the workforce recently enough to have a genuine work history. If you have 40 credits but only 15 were earned in the past 10 years, you do not meet the requirement, even though you have enough total credits.

What Happens If You Do Not Have Enough Credits

If you do not have enough work credits when you file for SSDI, the Social Security Administration will deny your claim based on insufficient work history. This is a separate decision from whether your medical condition qualifies as a disability.

You can reapply later if you return to work and earn additional credits. Each quarter you work and earn the required amount adds one more credit to your record. If you are close to the threshold, even a few quarters of work can make the difference.

If you do not meet SSDI requirements but have very limited income and resources, you may be able to receive Supplemental Security Income (SSI) instead. SSI does not have work credit requirements; it is based on financial need. You can explore both programs by contacting the Social Security Administration.

Self-Employment and Work Credits

Self-employment income counts toward work credits, but only if you report it on your tax return and pay self-employment tax. The Social Security Administration uses your net self-employment income (revenue minus business expenses) to calculate credits, not your gross income.

If you earn $1,550 or more in net self-employment income in a quarter, you earn one credit for that quarter, up to four credits per year. You must file a Schedule C (Profit or Loss from Business) with your tax return to report this income. If you do not file taxes or do not report self-employment income, the Social Security Administration has no record of it and cannot count it toward your credits.

Keep detailed records of your business income and expenses. If you later file for SSDI, you will need to show the Social Security Administration proof of your self-employment earnings — usually your tax returns for the years in question.

Frequently Asked Questions

Do work credits expire or disappear after a certain time?

No. Work credits do not expire. Once you earn a credit, it stays on your record permanently. This means you can work for several years, stop working, and still have those credits count toward SSDI many years later, as long as you meet the recency requirement if you are 31 or older.

Can I earn work credits while receiving SSDI?

Yes. If you return to work while receiving SSDI, you continue to earn work credits. However, your earnings may affect your SSDI payment amount or trigger a work incentive program review. Contact the Social Security Administration before returning to work to understand how it affects your benefits.

What if I worked in another country — do those credits count?

Credits earned in most other countries do not count toward SSDI. However, the United States has totalization agreements with some countries that allow workers to combine credits from both countries. Contact the Social Security Administration to learn whether your country has an agreement and how it applies to your situation.

How do I know if I meet the recency requirement?

Check your my Social Security account or your Statement of Earnings to see how many credits you earned in each year. Count backward 10 years from when your disability began. If at least 20 of your credits fall within that 10-year window, you meet the recency requirement (assuming you have 40 total credits).

Can I get credits for time I was not working, such as raising children or caring for a parent?

No. The Social Security Administration only counts credits you earned through paid work (wages or self-employment income). Caregiving, volunteering, or other unpaid work does not earn credits. However, some people may be able to receive benefits as a family member of someone who receives SSDI or retirement benefits, which is a different program.
