The Work Credit Requirement Depends on Your Age When You Become Disabled
Social Security counts your work history in work credits, not years of work. You earn one credit for each $1,730 of wages you report to Social Security in 2024 (this amount changes yearly). Most people need between 20 and 40 credits total to receive SSDI, but the exact number depends on how old you are when you become unable to work.
The younger you are, the fewer credits you typically need. A 22-year-old needs only 12 credits; a 30-year-old needs 20 credits; a 50-year-old needs 38 credits. The rule is that you need one credit for each year since you turned 21, up to a maximum of 40 credits (which you need if you are 62 or older when you file).
You can earn up to four credits per year, so you have some flexibility in when you earn them. You do not have to earn them all in recent years — Social Security looks at your entire work history, not just the last five years.
Key Takeaways
- You need one work credit for each year since you turned 21, with a minimum of 12 credits and a maximum of 40 credits required.
- A work credit is earned when you report $1,730 in wages to Social Security in 2024; you can earn up to four credits per year.
- Your age at the time you become disabled determines how many credits you need, not your age when you file.
- Self-employed income counts toward work credits the same way wages do, as long as you report it to Social Security.
Work Credit Requirements by Age
Social Security publishes the exact credit requirement for each age. If you become disabled at age 24, you need 14 credits. At age 28, you need 16 credits. At age 32, you need 20 credits. The pattern continues: add one credit for each year of age above 21, until you reach age 62, when the requirement caps at 40 credits.
The age that matters is the age you were when your disability began, not the age you are when you file for SSDI. If you became disabled at 26 but did not file until age 35, Social Security still counts you as disabled at 26 and uses the 18-credit requirement for that age.
| Age When Disabled | Credits Needed |
|---|---|
| 22 | 12 |
| 24 | 14 |
| 28 | 16 |
| 32 | 20 |
| 40 | 28 |
| 50 | 38 |
| 62 or older | 40 |
You can check your exact work credit count by creating a my Social Security account online at ssa.gov. Your account shows your earnings history and the number of credits you have earned so far. If you do not have an online account, you can request a paper statement by mail.
How Work Credits Are Earned and Counted
You earn one work credit for every $1,730 in wages you report to Social Security in 2024. This dollar amount is set by federal law and increases most years. In 2023, the amount was $1,640; in 2022, it was $1,550. You can earn a maximum of four credits per year, which means you need at least $6,920 in reported wages in a single year to earn the maximum four credits.
The wages must be reported to Social Security through payroll taxes (FICA). If you work for an employer, they report your wages automatically. If you are self-employed, you must report your net self-employment income on your tax return, and Social Security counts that income toward your work credits the same way.
Work credits do not expire. If you earned 30 credits by age 35 and then stopped working, those 30 credits remain on your record forever. You do not have to earn all your credits in recent years or in a row. Social Security looks at your entire work history from age 21 onward.
What Happens If You Do Not Have Enough Credits
If you do not have the required number of work credits for your age, you cannot receive SSDI. There is no exception or workaround based on financial need or the severity of your condition. The work credit requirement is a threshold you must meet.
However, you may be able to receive Supplemental Security Income (SSI) instead, which is a separate program that does not require work credits. SSI is based on financial need and disability, not work history. You can be receiving SSI while you continue to work toward the credits you need for SSDI, or you can receive SSI permanently if you never earn enough credits.
If you are close to having enough credits, you might be able to work part-time or return to work temporarily to earn the remaining credits you need. Even a few months of work can generate one or two additional credits if your earnings are high enough.
Recent Work Requirements: The 20/40 Rule
SSDI has a second requirement beyond the total credit count: you must have earned at least 20 of your required credits in the last 10 years (this is called the 20/40 rule). This rule applies to most people under age 31. For people 31 and older, the rule is slightly different but still requires recent work.
The purpose of this rule is to may support that you have worked recently enough that your disability is not from decades of inactivity. If you earned 30 credits but all of them were between ages 18 and 25, and you are now 50 and disabled, you would not meet the 20/40 requirement because your credits are too old.
The exact recent-work requirement depends on your age. Social Security publishes the specific rules for each age group. Your my Social Security account will show whether you meet this requirement, or you can ask a Social Security representative when you file.
How to Check Your Work Credit Count
The fastest way to see how many credits you have earned is to log into your my Social Security account at ssa.gov. You will need to create an account with a username and password, or sign in using your existing credentials. Once logged in, select "Earnings Record" to see your reported wages by year and your total credit count.
If you do not want to create an online account, you can request a paper statement by mail. Call Social Security at 1-800-772-1213 and ask for a Statement of Earnings. The statement will arrive in about two weeks and will show your earnings history and work credits.
If you see an error in your earnings record — for example, wages you earned but do not see reported — you can correct it by contacting Social Security with documentation like W-2 forms or tax returns. Corrections can take several months, so report errors as soon as you notice them.
Work Credits for People Who Became Disabled Young
If you became disabled before age 22, you have a separate rule. You need only six credits earned in the three years before your disability began. This rule exists because young people have not had time to build a long work history.
For example, if you became disabled at age 19, you need six credits earned between ages 16 and 19. If you became disabled at age 20, you need six credits earned between ages 17 and 20. The credits must be recent — they cannot be from years before your disability started.
If you do not meet the six-credit requirement, you may still be able to receive SSI based on your disability and your family's financial situation. SSI does not require work credits and can provide support to disabled people of any age.
Frequently Asked Questions
Can I earn work credits after I become disabled?
Yes. If you work while receiving SSDI, you can earn additional credits. However, your earnings may affect your SSDI payment amount or trigger a work incentive review. Report any work to Social Security so they can calculate your benefits correctly.
Do credits from other countries count toward SSDI?
Generally, no. Social Security only counts credits earned from U.S. wages reported to Social Security. However, some countries have agreements with the U.S. that allow credits to be combined. Ask Social Security whether your country has a totalization agreement.
What if I worked under different names or Social Security numbers?
Contact Social Security when ready. Wages earned under a different name or number may not appear on your record. Social Security can correct this if you provide documentation like marriage certificates or name-change orders, but the process takes time.
Do I need 40 credits if I am already receiving retirement benefits?
No. If you are already receiving Social Security retirement benefits, you do not need to meet the SSDI work credit requirement. You can switch to SSDI if your condition meets the disability definition, and your payment will be based on your retirement benefit amount.
What happens to my credits if I do not work for several years?
Your credits do not disappear. Work credits are permanent once earned. However, you may fail to meet the recent-work requirement (the 20/40 rule) if you have not worked recently enough. Check your account to see whether you still meet both the total credit count and the recent-work requirement.
