The Basic Work Credit Requirement for SSDI
To receive Social Security Disability Insurance (SSDI), you must have earned enough work credits by the time you become disabled. The Social Security Administration (SSA) does not count years of work directly. Instead, it counts credits you earn each year you pay Social Security taxes on your wages.
In 2024, you earn one work credit for every $1,730 in wages you make (this amount changes each year). You can earn a maximum of four credits per year, which means you need at least $6,920 in annual earnings to max out your credits for that year. Most people who work a regular job earn four credits per year without thinking about it.
The total number of credits you need depends on your age when you become disabled. Younger workers need fewer credits than older workers. The SSA uses a formula: you generally need 40 credits total, with at least 20 of those credits earned in the 10 years before you became disabled.
Key Takeaways
- You earn work credits by paying Social Security taxes on your wages, not by straightforward working a certain number of years.
- You need 40 total work credits to may have access to for SSDI, with at least 20 earned in the 10 years when ready before your disability began.
- If you became disabled before age 24, you may need as few as 6 credits earned in the 3 years before disability.
- Self-employed income counts toward work credits if you pay self-employment tax, and you can earn up to four credits per year regardless of how much you earn above the threshold.
- The SSA will review your complete earnings record when you file, so you should request a Statement of Earnings from SSA to verify your credits before explore.
How Work Credits Accumulate Over Time
Work credits are tied to your earnings record, which the SSA maintains based on your Social Security number. Every time you work and your employer withholds Social Security tax (6.2% of your wages), you are earning credits toward SSDI. If you are self-employed, you pay self-employment tax (15.3% total, which includes both the employer and employee portions), and those earnings also count.
The credit threshold changes annually. In 2023, you needed $1,640 per credit; in 2024, it rose to $1,730. The SSA announces the new amount each October for the following year. This means the amount of money you need to earn per credit increases slightly most years, but the number of credits you need (40 total) stays the same.
Once you earn a credit, you keep it forever. If you worked for five years, stopped working for ten years, then worked again, the credits from your first five years still count. The SSA does not remove old credits from your record just because time has passed.
Different Credit Requirements by Age at Disability
The SSA uses your age when you became disabled to determine how many credits you actually need. This is called the "recency of work" requirement, and it exists because younger workers have had less time to build a work history.
| Age When Disabled | Total Credits Needed | Credits Needed in Last 10 Years |
|---|---|---|
| Before age 24 | 6 credits | 6 credits in last 3 years |
| Age 24–30 | 12 credits | 12 credits in last 3 years |
| Age 31–42 | 20 credits | 20 credits in last 10 years |
| Age 43 or older | 40 credits | 20 credits in last 10 years |
A 22-year-old who becomes disabled needs only 6 credits, which could be earned in roughly 1.5 years of full-time work. A 45-year-old needs 40 credits total, but only 20 of those need to be from the past 10 years. This means an older worker could have worked steadily in their 20s and 30s, taken time off, and still have enough credits if they worked recently enough.
How to Check Your Work Credits
The SSA keeps an official record of your earnings and the credits you have earned. You can view this record by creating a my Social Security account at ssa.gov. Once you log in, you can see your Statement of Earnings, which lists your reported earnings for each year and the credits you earned.
You should review your Statement of Earnings before you file for SSDI, especially if you have worked for multiple employers, changed your name, or worked in different states. Errors on your record are not uncommon—a missing year of earnings, a misspelled name, or an employer who did not report your wages correctly can reduce your credit count.
If you find an error, you can file a correction request with the SSA. You will need to provide documents such as W-2 forms, pay stubs, or tax returns that show the correct earnings. The SSA typically has a three-year window to correct errors, though some corrections can be made outside that window in certain circumstances.
Work Credits for Self-Employed Workers
If you are self-employed, your work credits are based on your net self-employment income reported on your tax return (Schedule C for sole proprietors). You must pay self-employment tax to earn credits. The income threshold for self-employment credits is the same as for wage earners: in 2024, you need $1,730 in net self-employment income to earn one credit.
Self-employed workers can also earn up to four credits per year, just like wage earners. If your net self-employment income is $6,920 or more in a year, you earn the maximum four credits for that year. If your income is lower, you earn fewer credits proportionally.
One important difference: if you are self-employed and become disabled, the SSA may scrutinize your work history more closely. You will need to provide tax returns, business records, and documentation of when your disability actually began. The SSA wants to confirm that you were genuinely working and earning income, not just reporting inflated figures.
What Happens If You Do Not Have Enough Credits
If you do not have enough work credits when you become disabled, you cannot receive SSDI. However, 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 different rules: it looks at your current income and assets, not your work history.
If you are close to having enough credits but not quite there, you might consider whether waiting a few more months or years is possible. Each additional year of work adds up to four more credits to your record. However, this only makes sense if your condition allows you to continue working and if you can afford to wait.
Another option is to file for SSDI anyway. The SSA will review your complete record and let you know if you are denied due to insufficient credits. If you are denied, you can appeal, though the appeal process cannot change the credit requirement itself—only the SSA's calculation of your credits can be appealed.
Frequently Asked Questions
Do I need to work for a certain number of years in a row to get SSDI?
No. Your work credits do not need to be consecutive. You can work for three years, take ten years off, work for two more years, and still use all those credits. What matters is the total number of credits and, for older workers, whether at least 20 of them were earned in the 10 years before your disability began.
If I worked part-time, can I still earn four credits per year?
Yes. The number of credits you earn depends on your total earnings for the year, not on whether you worked full-time or part-time. If you earned $6,920 or more in 2024 (whether over 12 months or a shorter period), you earned four credits. If you earned $3,460, you earned two credits.
What if I worked in another country before moving to the United States?
Work you performed outside the United States generally does not count toward SSDI credits, with limited exceptions. The SSA has totalization agreements with some countries that allow work in those countries to count, but you would need to contact the SSA directly to learn about your country is included.
Can my spouse's work credits help me get SSDI?
No. SSDI is based only on your own work record. Your spouse's credits do not transfer to you. However, if you are denied SSDI but your spouse receives Social Security retirement or disability benefits, you may be able to receive spousal benefits based on their record instead.
Do I lose my work credits if I do not work for several years?
No. Once you earn a credit, it stays on your record permanently. You do not need to work continuously to keep your credits. However, if you become disabled and do not have enough recent credits (at least 20 in the past 10 years, for most workers), you will not meet the recency requirement even if you have 40 total credits.
