The Work Credit Requirement for SSDI
To receive Social Security Disability Insurance (SSDI), you must have earned enough work credits through payroll taxes. The number you need depends on your age when your disability began. Most people under 62 need 40 credits total, with at least 20 of those credits earned in the 10 years before the disability started. If you became disabled before age 24, the requirement is lower.
Work credits are not the same as years worked. You earn one credit for every $1,550 of wages you report to Social Security in 2024 (this amount changes yearly). You can earn a maximum of four credits per year, which means you need at least 10 years of work history to reach 40 credits, but the work does not have to be continuous.
Social Security counts the credits you have already earned. You do not need to earn them all before you file. If you have 20 credits in the past 10 years and are under 62, you meet the recency requirement even if your total is below 40.
Key Takeaways
- Most people need 40 work credits total, with 20 earned in the 10 years before disability began.
- You earn one credit per $1,550 of reported wages (in 2024), and you can earn up to four credits per year.
- If you became disabled before age 24, you may need as few as 6 credits, with half earned in the three years before disability.
- Work credits are based on wages you reported to Social Security through payroll taxes, not on the jobs you held.
How Work Credits Are Earned and Counted
A work credit is tied to your reported wages, not to time on the job. When your employer withholds Social Security tax from your paycheck, those wages are reported to your Social Security account. Self-employed workers report earnings on their tax return. Social Security converts your annual earnings into credits based on a threshold that changes each year.
In 2024, you earn one credit for each $1,550 of wages. In 2023, the threshold was $1,470. The threshold typically rises each year with national wage growth. Because you can earn only four credits per year (one per quarter), you need a minimum of 10 years of work to accumulate 40 credits, but those years do not have to be recent or consecutive.
Social Security keeps a record of your earnings history. You can view your own record online through your my Social Security account or by requesting a Statement of Earnings from Social Security. This record shows how many credits you have earned to date and is the basis Social Security uses to determine whether you meet the work credit requirement.
Credit Requirements by Age at Disability
The number of credits you need depends on how old you were when your disability began. Social Security uses age brackets to set different thresholds for younger workers, because they have had less time to build a work history.
| Age When Disability Began | Total Credits Needed | Credits Needed in Past 10 Years |
|---|---|---|
| 31 or older | 40 | 20 |
| 24 to 30 | 32 to 39 | 20 |
| 21 to 23 | 20 | 20 |
| Under 21 | 6 | 6 in past 3 years |
If you were 24 to 30 when disability began, the exact number of credits you need falls between 32 and 39, based on your specific age. Social Security will calculate the precise requirement for your age. The key point is that younger workers do not need the full 40 credits, but they still must have earned most of those credits recently.
If you were under 21 when disability began, you need only 6 credits, and all 6 must have been earned in the three years before the disability started. This is the lowest threshold and reflects the reality that very young workers have had minimal time to build a work history.
What Happens If You Do Not Have Enough Credits
If you do not have enough work credits, you cannot receive SSDI based on your own work record. However, you may be able to receive benefits as a family member of someone else who is receiving or may have access to to Social Security. A spouse, ex-spouse, or adult child of a disabled worker may be able to claim on that worker's record if they meet other requirements.
If you are close to meeting the work credit requirement, you may want to continue working if you are able to do so. Each quarter you work and report wages, you earn additional credits. Some people delay filing until they have accumulated enough credits, though this is only an option if your condition allows you to work.
If you have never worked or have very few credits, you may be able to explore for Supplemental Security Income (SSI) instead. SSI is a needs-based program that does not require work credits. It has different rules and lower income and resource limits, but it may be an option if you are disabled and have limited income and assets.
How Social Security Verifies Your Work Credits
When you file for SSDI, Social Security pulls your earnings record automatically. The agency has records of all wages reported to your Social Security number by employers and self-employment income you reported on tax returns. You do not have to submit pay stubs or W-2 forms to prove your credits, though you may be asked to provide them if there is a discrepancy.
If you believe your earnings record is incomplete or incorrect, you can request a Statement of Earnings and ask Social Security to correct it. You have a limited time to challenge earnings from past years, so if you notice missing or wrong information, contact Social Security as soon as possible. Corrections can take several months, so it is worth checking your record before you file.
Social Security will tell you in your decision letter whether you meet the work credit requirement. If you do not, the letter will explain why and may mention other programs you might be able to use instead.
Work Credits and Continuing may be able to access
Once you are approved for SSDI, your work credits do not affect your ongoing benefits. You do not need to maintain a certain number of credits to keep receiving SSDI. However, if you return to work and earn above a certain amount, your benefits may be reduced or stopped under the substantial gainful activity (SGA) rules, which are separate from work credit requirements.
If your SSDI benefits are stopped because you returned to work, you may be able to restart them later if you stop working and your condition has not improved. The rules for restarting benefits are complex and depend on how long you worked and how much you earned.
Frequently Asked Questions
Can I use work credits from a job I had 20 years ago?
Yes, if you are 31 or older. All 40 credits count toward your total, no matter when you earned them. However, you still need 20 of those credits to have been earned in the 10 years before your disability began. Credits from 20 years ago can count toward the 40-credit total but not toward the recency requirement.
What if I worked part-time or had gaps in employment?
Part-time work counts as long as you reported wages to Social Security. Gaps in employment do not hurt you — credits are based on wages reported, not on continuous work. You can earn credits in some years and not others, and still reach 40 credits over time.
Do military service credits count toward SSDI?
Military service before 1968 may earn you deemed credits. If you served on active duty before 1968, Social Security may add credits to your record. You do not have to request this — Social Security adds them automatically if you are may have access to to them. Military service after 1968 does not earn deemed credits unless you were disabled in service.
If I am self-employed, how do I earn work credits?
Self-employed income is reported on your tax return (Schedule C or Schedule SE). Social Security counts your net self-employment income the same way it counts wages from an employer. You must report at least $1,550 in net self-employment income in 2024 to earn one credit. The threshold changes yearly.
Can I check how many work credits I have before I file?
Yes. Create a my Social Security account online at ssa.gov, or call Social Security at 1-800-772-1213 to request a Statement of Earnings. The statement shows your earnings history and the number of credits you have earned. Checking before you file can help you know whether you meet the requirement.
