Do Social Security Work Credits Expire?
The short answer is that Social Security work credits do not expire for retirement benefit eligibility, but they are subject to specific recency requirements for disability benefits. This critical distinction is based on the type of benefit you are applying for. The Social Security Administration (SSA) uses work credits as a measurement of your work history and contributions to the system, not as a time-sensitive currency that can disappear.
For retirement benefits, the rule is straightforward. If you were born in 1929 or later, you need a total of 40 credits, which is equivalent to about 10 years of work. These credits do not need to be consecutive, and they will stay on your record indefinitely, even if you leave the workforce for an extended period. The credits simply serve as an eligibility gate, and once you've met the 40-credit threshold, you are considered "fully insured" for retirement.
For Social Security Disability Insurance (SSDI), the rules are more complex and depend on your age. To qualify for SSDI, you must pass both a "duration of work" test and a "recent work" test. The recent work test is where the concept of a credit's recency becomes important. It's not that the credits disappear, but that you must have earned a certain number within a specific time frame just before the onset of your disability. This is to ensure that a claimant has a recent connection to the workforce. This recent work requirement is what many people mistake for credits expiring.
Credit Accumulation and Requirements
To understand eligibility, you first need to know how credits are earned. For the year 2025, you receive one credit for every $1,810 in covered earnings, with a maximum of four credits per year. This dollar amount adjusts annually based on average wage increases. No matter how high your income, you can never earn more than four credits in a single year.
Requirements for Different Benefits
The number of credits you need varies by the type of benefit you are applying for:
- Retirement Benefits: You need a total of 40 credits, or about 10 years of work. There is no time limit for when these credits were earned.
- Disability Benefits (SSDI): The number of credits and the recency of your work are both factors. For most workers aged 31 or older, the rule requires 20 credits in the 10 years leading up to the disability. For younger workers, the requirements are less stringent.
- Survivors Benefits: The number of credits needed depends on the deceased worker's age at the time of death, but it can be as few as six credits earned in the three years before death for certain family members. No one ever needs more than 40 credits.
The "Date Last Insured" for Disability
An important concept related to disability benefits is the Date Last Insured (DLI). This is the last date that you are considered insured for disability benefits under Social Security. For most workers who have stopped working, their insured status for disability typically lasts about five years after they stop paying FICA taxes. If your disability begins after your DLI, you will generally not be eligible for SSDI, regardless of how many total lifetime credits you have.
Retirement vs. Disability Credit Rules
The rules for retirement and disability are fundamentally different regarding the permanence of credits. Here is a comparison to clarify the key points:
| Feature | Retirement Benefits | Disability Benefits (SSDI) |
|---|---|---|
| Credit Expiration | Credits never expire once earned. | Credits for the "recent work" test can become too old to count for eligibility. |
| Recency Requirement | No recency requirement. Credits can be from any point in your work history. | Yes, a "recent work" test applies, especially for workers over 31. |
| Credits Needed | A lifetime total of 40 credits is required for most. | Varies by age. Workers 31+ generally need 20 credits in the last 10 years. |
| Key Concept | "Fully Insured" status based on lifetime earnings. | "Recent work test" and "Date Last Insured" (DLI) are critical factors. |
| Benefit Calculation | Based on your highest 35 years of indexed earnings. | Based on your average lifetime earnings, but only if you are insured at the time of disability. |
What to Do If You Have a Work Gap
If you have a gap in your employment history, here's what you need to know:
- For Retirement: A gap in work will not cause your existing credits to expire. When you return to the workforce, you will simply continue adding to your lifetime credit total. However, years with low or no earnings will be counted as zeros when the SSA calculates your average lifetime earnings, which may result in a lower monthly benefit. Working more years can replace those zero-earning years with higher amounts, potentially increasing your eventual benefit.
- For Disability: A work gap is more problematic for SSDI eligibility. If you become disabled after your DLI has passed (typically five years after you stop working), you may no longer be eligible for SSDI benefits, even if you have far more than 40 lifetime credits. In this case, you might need to explore other options, such as Supplemental Security Income (SSI), which is a needs-based program and does not depend on work credits.
Conclusion
Ultimately, the lifespan of Social Security work credits depends on the benefit in question. For retirement, credits are permanent and do not expire. A lifetime total of 40 credits is all that is needed for eligibility. For disability, the rules are more complicated, and the recency of your work is a critical factor. The Date Last Insured (DLI) can effectively make older credits irrelevant for SSDI if your disability onset is too far after you stop working. This distinction is crucial for financial planning, especially for those considering leaving the workforce or who may face a future disability.
To monitor your status, the SSA recommends creating a secure online account to view your Social Security Statement and review your credited earnings. It is essential to ensure your earnings record is accurate to protect your future eligibility for all types of benefits.

How Can I Check My Work Credit Status?
To see how many credits you have accumulated, you can create a personal "my Social Security" account on the Social Security Administration's website (ssa.gov). This account allows you to view your Social Security Statement, which includes a detailed record of your credited earnings.
What Are Social Security Work Credits?
Social Security work credits are units earned by working and paying FICA taxes. For the year 2025, you earn one credit for each $1,810 in earnings, up to a maximum of four credits per year. Credits are used to determine eligibility for retirement, disability, and survivors benefits, but do not affect the amount of your benefit.
What if I Stop Working for Many Years?
If you stop working for several years, your earned credits for retirement benefits will not expire. However, for disability benefits, you may lose your "insured" status if your disability begins more than five years after you stop working. For retirement, years without earnings will be included as zeros in your benefit calculation, potentially lowering your monthly payment.
Do I need 40 credits for every type of Social Security benefit?
No, you do not need 40 credits for every benefit. While retirement benefits generally require 40 credits, disability and survivors benefits have different, and sometimes lesser, credit requirements based on the worker's age.
How do credits work if I'm self-employed?
If you are self-employed, you earn Social Security credits in the same way as an employee by paying self-employment taxes. As long as you report your net earnings, you can earn up to four credits annually.
Can I still receive benefits if I don't have enough credits?
Yes, there are a few options. If you don't have enough work credits for retirement, you may still be eligible for spousal or survivors benefits based on your spouse's work record. If you have limited income and resources, you may be eligible for Supplemental Security Income (SSI), a needs-based program that does not depend on work credits.
How do Social Security credits affect Medicare eligibility?
Your work credits also count towards premium-free Medicare Part A. If you or your spouse have 40 work credits, you will likely be eligible for premium-free Part A when you turn 65.
