What work credits are and how they count toward SSDI
Work credits are the currency Social Security uses to measure whether you have worked enough to be covered by SSDI. You earn one credit for every $1,730 of wages you make in a year (this dollar amount changes each year, so the threshold will be different in 2025 than it was in 2024). You can earn a maximum of four credits per year, no matter how much you earn above that threshold.
The reason Social Security uses credits instead of just counting years worked is that it rewards consistent work over time. Someone who worked full-time for five years earns the same number of credits as someone who worked part-time for ten years, as long as both earned enough in each year to get four credits. The system is designed so that you do not have to work every single year of your life to may have access to.
When you explore for SSDI, Social Security will count up all the credits you have earned since you turned 21 (or since 1978, whichever is later). That total determines whether you meet the work requirement for your age group.
Key Takeaways
- You earn one work credit for every $1,730 you earn in wages during a year, with a maximum of four credits per year.
- The dollar amount needed to earn one credit increases most years, so you should check the current year's threshold before calculating your own credits.
- Self-employment income counts toward work credits the same way wages do, but you must report it on your tax return.
- Social Security keeps a record of your earnings history, and you can view your estimated credits on your personal my Social Security account online.
- You do not need to have worked recently to may have access to for SSDI — credits you earned years ago still count toward your total.
How the dollar threshold works each year
Social Security announces the credit threshold each October for the coming year. In 2024, you needed to earn $1,730 to get one credit. In 2023, it was $1,640. The amount goes up most years because of wage growth, but it does not go down.
The way the math works: if you earned $6,920 in a year, you would get four credits (one for each $1,730). If you earned $3,460, you would get two credits. If you earned $1,729, you would get zero credits for that year — you have to hit the threshold to get the credit.
You do not need to earn all four credits' worth in a single job. If you worked two part-time jobs and earned $1,730 combined, that counts as one credit. The only thing that matters is your total earnings for the year.
Self-employment income and work credits
If you are self-employed, your net self-employment income counts toward work credits the same way wages do. You calculate this as your gross income minus business expenses. Social Security will use the amount you report on your federal tax return (Schedule C if you file as a sole proprietor).
Self-employed people often miss this because they think only W-2 wages count. They do not. As long as you file taxes and report your self-employment income, those earnings build work credits just like any other job would.
If you have not filed taxes on your self-employment income, you will need to file back returns to get those years credited. This is worth doing if you are close to meeting the work requirement for SSDI, because the credits can make the difference between approval and denial.
Checking your work credit record
Social Security maintains an earnings record for every person with a Social Security number. You can see your own record by creating an account on my Social Security, the official Social Security website. Once you log in, you can view your estimated work credits and your year-by-year earnings history.
This record is important to check before you explore for SSDI, because errors do happen. If Social Security has you down as earning less than you actually did in a particular year, your work credit count will be wrong. You have the right to correct the record if you find a mistake.
If you spot an error, you will need to contact Social Security with proof of your actual earnings — usually a tax return, W-2, or pay stub from that year. Social Security can then update your record. This process can take several weeks, so it is worth doing early if you are planning to explore for SSDI.
How many credits you need based on your age
The number of credits required depends on how old you are when you become disabled. Generally, the younger you are, the fewer credits you need — but you still need to have worked some in recent years.
If you are 31 or older, you typically need 20 credits earned in the 10 years before you became disabled. This is the most common requirement. If you are between 24 and 30, the requirement is lower — usually half the credits needed for someone your age to retire. If you became disabled before age 24, you may need as few as 6 credits earned in the 3 years before you became disabled.
There is also a "recency" rule: you generally need to have earned at least 20 of your required credits in the 10 years right before you became disabled. This means you cannot rely entirely on credits you earned 20 years ago. Social Security wants to see that you were working relatively recently.
What counts and what does not count toward credits
Only earned income counts toward work credits. This means wages from a job and net self-employment income. Investment income, rental income, unemployment benefits, disability benefits, and Social Security retirement benefits do not count.
Volunteer work does not count, even if you were paid a small stipend. Work done for a family business where you are also an owner may not count, depending on the circumstances. If you are unsure whether a particular type of income counts, you can ask Social Security directly or check your earnings record to see whether they have already counted it.
Work you did before you turned 21 does not count toward SSDI work credits (though it may count toward other Social Security benefits). Social Security starts counting your work history from age 21 forward.
Credits you earned years ago still count
One of the most important things to understand is that work credits do not expire. If you earned four credits in 2010 and have not worked since, those credits are still there when you explore for SSDI in 2025. They count toward your total just as much as credits you earned last year.
This matters because many people think they have to have worked recently to may have access to for SSDI. That is not true. You need to have worked recently enough to meet the "recency" requirement (usually 20 credits in the past 10 years), but the older credits you earned still add to your total.
If you became disabled and have not worked in several years, your old credits are still there. The question is whether you have enough total credits and whether you meet the recency requirement for your age. Social Security will look at your entire work history to answer that.
Frequently Asked Questions
Do I need to have worked in the year I became disabled?
No. You need to meet the recency requirement, which usually means 20 credits earned in the 10 years before you became disabled, but you do not need to have worked in the exact year you became disabled. If you became disabled in June and had not worked since January, the credits you earned earlier in that year would still count.
What if I worked under a different Social Security number?
Contact Social Security and explain the situation. You will need to provide proof of your identity and your work history under the other number. Social Security can consolidate earnings records, but you have to report it so they know to look for the other account.
Can I earn credits while receiving unemployment benefits?
No. Unemployment benefits do not count as earned income and do not generate work credits. Only wages or self-employment income count. If you are working part-time while receiving unemployment, the wages from that work do count.
How do I know if my earnings record is correct?
Log into my Social Security and review your year-by-year earnings history. Compare it to your tax returns and W-2s from the same years. If you see a difference, contact Social Security with proof of your actual earnings. They can correct the record if you provide documentation.
Do credits I earned before age 21 count toward SSDI?
No. Social Security only counts work credits you earned from age 21 onward for SSDI purposes. Work you did as a teenager does not count, even if you paid into Social Security through payroll taxes.
