The Basic Credit Requirement for SSDI
You 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 Social Security Administration (SSA) calls this the "recent work requirement," and it exists because SSDI is meant to replace income you would have earned if you could work.
A work credit is not the same as a paycheck. You earn one credit for every $1,550 of wages you report to Social Security in 2024 (this dollar amount changes each year). You can earn a maximum of four credits per year, which means you reach four credits by earning $6,200 in a single year. The SSA counts credits based on your Social Security earnings record, which is built from the taxes withheld from your paychecks or self-employment income.
The 40-credit rule applies to most people under 62. If you became disabled before age 24, the rules are different and require fewer credits. If you are explore for SSDI as a widow, widower, or adult child of a worker who died, you do not need to meet the credit requirement yourself — your parent's or spouse's record is what matters.
Key Takeaways
- You need 40 work credits total, with at least 20 earned in the 10 years before you became disabled.
- You earn one credit for every $1,550 of reported wages in 2024; the dollar amount increases slightly each year.
- You can earn a maximum of four credits per year, so the 40-credit requirement takes at least 10 years of work to meet.
- If you became disabled before age 24, you may need only six to 18 credits depending on your exact age.
- Your Social Security earnings record must show the work history; credits earned but not reported to SSA do not count.
How the 10-Year Recent Work Window Works
The "recent work" part of the rule means that 20 of your 40 credits must come from the 10-year period when ready before you became disabled. This requirement prevents someone from working steadily 30 years ago, then explore for SSDI decades later without any recent work history.
The 10-year window is measured backward from the date SSA considers you disabled, not from the date you file your claim. If you stopped working in January 2024 due to illness, SSA looks back to January 2014 as the start of your 10-year window. Any credits you earned before January 2014 count toward your 40-credit total, but they do not count toward the 20-credit recent work requirement.
This means you could theoretically meet the requirement with work spread unevenly across the decade. For example, you might have earned 15 credits between 2014 and 2019, then earned five more credits between 2020 and 2024. Both groups count toward the 20-credit recent work requirement because both fall within the 10-year window.
Credit Requirements for Younger Workers
If you became disabled before age 24, you do not need 40 credits. The SSA uses a sliding scale based on your age at the time you became disabled.
| Age When Disabled | Credits Needed |
|---|---|
| Before age 24 | Six credits (earned in the three years before disability) |
| Age 24 to 30 | Credits equal to the number of years from age 21 to the age you became disabled, with a minimum of six |
| Age 31 or older | 40 credits (20 earned in the 10 years before disability) |
For someone who became disabled at age 26, for example, SSA would require five years of work history (from age 21 to 26), which translates to roughly 20 credits. The exact calculation depends on your birth month and the month you became disabled, so SSA will compute this for you when you file.
How Credits Appear on Your Earnings Record
Your credits are recorded on your Social Security earnings record, which you can view online through your my Social Security account at ssa.gov. The record shows the year, the amount of wages you reported, and the number of credits you earned that year. You should review this record before you file for SSDI because errors can delay your claim.
Credits only count if the wages were reported to Social Security. If you were paid in cash and never reported the income, or if your employer failed to report your wages, those earnings do not create credits. Self-employed workers must report their net self-employment income on their tax return; SSA pulls the information from your tax records.
If you spot an error on your earnings record — a missing year of work, wages listed under the wrong year, or wages that seem too low — you can request a correction. You will need to provide documents like W-2 forms, pay stubs, or tax returns as proof. SSA has a time limit for corrections, so address errors as soon as you notice them.
The Annual Dollar Amount for Credits Changes Each Year
The amount of wages you need to earn one credit is adjusted each year based on national wage trends. In 2024, you need $1,550 in wages to earn one credit. In 2023, the amount was $1,470. In 2022, it was $1,510.
This annual adjustment means that the total wages needed to earn four credits in a year also changes. In 2024, you need $6,200 in total wages to earn the maximum four credits for that year. If you earned $6,200 or more in 2024, you automatically earned four credits for that year, regardless of how the wages were distributed across the months.
SSA publishes the annual credit amount in October for the following year. If you are working and tracking your progress toward the 40-credit requirement, you can check the current year's amount on the SSA website or ask your local Social Security office.
What Happens If You Do Not Have Enough Credits
If you do not meet the credit requirement, SSA will deny your SSDI claim. You cannot receive SSDI benefits, but you may be able to receive Supplemental Security Income (SSI) instead, which is a needs-based program that does not require work credits. SSI has its own rules about income and resources, and the monthly payment is usually lower than SSDI.
If you are close to meeting the credit requirement, you might be able to delay your claim. For example, if you have 38 credits and are still working, you could earn two more credits in the next year or two and then file. However, delaying only makes sense if you can continue working without worsening your condition. If your disability prevents you from working now, you should file even if you are short a few credits, because SSA will make a information based on what you have.
Some people become disabled while still building their work history. If you do not have 40 credits yet but expect to reach that number through continued work, you can ask SSA about your progress. They can tell you exactly how many more credits you need and when you might reach that goal if your work continues at the current pace.
Credits for Family Members on Your Record
If you are receiving SSDI, your spouse, ex-spouse, and children may be able to receive benefits on your work record without needing their own credits. These are called auxiliary benefits, and they are based entirely on your credit history and earnings record, not theirs.
Your spouse can receive benefits at age 62 or at any age if they are caring for your child under age 16. Your ex-spouse can receive benefits at age 62 if the marriage lasted at least 10 years. Your unmarried children can receive benefits until age 19 if they are in high school full-time, or until age 18 if they are not in school. Children with disabilities can receive benefits for life, regardless of age.
The total amount paid to your family members comes from your benefit amount and is called the family maximum. It is usually between 150 and 180 percent of your monthly SSDI payment. If multiple family members are receiving benefits, each person's payment is reduced so the total does not exceed the family maximum.
Frequently Asked Questions
Can I earn credits from work I did before I was 18?
Yes. Any wages you reported to Social Security count toward your credits, regardless of your age when you earned them. If you worked part-time as a teenager and your employer reported your wages, those credits count. You can view your complete earnings record, including teenage work years, on your my Social Security account.
What if I worked in another country before moving to the United States?
Work you did in another country generally does not count toward SSDI credits unless you were a U.S. citizen at the time or the country has a totalization agreement with the United States. SSA has totalization agreements with about 30 countries that allow work in both countries to be combined. Contact your local Social Security office to ask whether your country has an agreement.
Do I lose credits if I do not work for several years?
No. Credits you have already earned stay on your record permanently. If you earned 30 credits by age 35, then did not work for 10 years, you still have those 30 credits. However, you would need to earn 10 more credits within the 10-year window before you became disabled to meet the recent work requirement.
Can I check how many credits I have right now?
Yes. Create a my Social Security account at ssa.gov and view your earnings record. It shows the credits you earned each year. You can also call Social Security at 1-800-772-1213 or visit your local office to ask how many credits you have and how many more you need.
What if SSA says I have fewer credits than I think I earned?
Request a detailed earnings record and compare it to your W-2 forms or tax returns. If there is a discrepancy, file a request for correction with SSA. You will need to provide documents showing the wages you earned. SSA has a time limit for corrections, so act quickly if you find an error.
