The Basic Rule: Work Credits, Not Years
Social Security Disability Insurance (SSDI) does not require you to work for a set number of years. Instead, the Social Security Administration counts work credits — which you earn by paying Social Security taxes on your wages. You need a certain number of credits to be found may be able to access for SSDI, and the number depends on your age when your disability begins.
You earn one work credit for every $1,730 of wages you earn in a year (this dollar amount changes each year). You can earn a maximum of four credits per year, regardless of how much you earn. This means the fastest path to gathering credits is to work and earn at least $6,920 in a single year — but most people accumulate credits over many years at a slower pace.
The connection between years worked and credits earned is loose. You could work part-time for 15 years and have fewer credits than someone who worked full-time for 5 years. What matters is the total number of credits you have accumulated, not the calendar span.
Key Takeaways
- You need between 20 and 40 work credits to be found may be able to access for SSDI, depending on your age when disability begins.
- You earn one credit for every $1,730 of wages in a year (as of 2024), with a maximum of four credits per year.
- Most people under 30 need 20 credits; people 31 to 42 need 20 plus additional credits based on age; people 43 and older need up to 40 credits.
- You can check your exact credit count by creating an account on ssa.gov or requesting a Social Security Statement by mail.
- Credits do not expire, but you must have earned them within a recent time window — usually within the last 10 years — to count toward SSDI.
Credit Requirements by Age at Disability Onset
The Social Security Administration uses a sliding scale based on how old you are when your disability begins. Younger workers need fewer total credits because they have had less time to accumulate them.
| Age When Disability Begins | Work Credits Needed |
|---|---|
| Before age 24 | 6 credits (earned in the 3 years before disability) |
| Age 24–30 | 20 credits |
| Age 31–42 | 20 credits, plus 1 additional credit for each year after age 21 (up to 40 total) |
| Age 43 and older | 40 credits |
For example, if you become disabled at age 35, you need 20 credits plus 14 additional credits (one for each year from age 21 to age 35), which totals 34 credits. If you become disabled at age 50, you need the full 40 credits.
The Social Security Administration also requires that you have earned a certain number of credits recently. For most people, you must have earned at least 20 of your required credits in the 10 years before your disability began. This "recency" rule prevents someone from working briefly decades ago and then claiming SSDI without recent work history.
How to Calculate Your Own Credit Count
You can see exactly how many credits you have earned by checking your Social Security record. The fastest way is to create a my Social Security account at ssa.gov. Once you log in, your earnings record and credit count appear under the "Earnings Record" tab. The page shows which years you earned credits and how many you earned each year.
If you do not have an online account, you can request a Social Security Statement by mail. Visit ssa.gov/myaccount and select "Create an Account," or call 1-800-772-1213 to request a paper statement. The statement arrives in about two weeks and lists your earnings year by year and your total credit count.
Your earnings record may contain errors — a wage reported under the wrong name or Social Security number, or a year of work that was not reported at all. If you spot a mistake, contact Social Security with documentation (pay stubs, W-2 forms, or tax returns). Corrections can take several months, so report errors as soon as you notice them.
The Difference Between Recent Work and Total Credits
Social Security requires both a total number of credits and recent work history. You might have 40 credits in your record but still not meet the recency requirement if most of those credits were earned 15 years ago.
The recency rule is: you must have earned at least 20 of your required credits in the 10-year period ending when your disability began. If you need 40 credits total but only 5 of them were earned in the past 10 years, you do not meet the recency test, even though you have enough total credits.
This rule is why someone who worked steadily for 20 years, then stopped working and became disabled 12 years later, might not be found may be able to access. The older credits do not count toward the recency requirement. You would need to have earned recent credits to bridge the gap.
What Happens If You Do Not Have Enough Credits
If you do not have the required number of credits or do not meet the recency requirement, you cannot be found may be able to access for SSDI based on your own work record. However, you may be found may be able to access based on someone else's record — a spouse, ex-spouse, or parent — if you meet other conditions.
You can also explore Supplemental Security Income (SSI), a separate program that does not require work credits. SSI is based on financial need rather than work history. To be found may be able to access for SSI, your income and resources must fall below certain limits set by Social Security. The income and resource limits vary by state and change each year.
If you are close to having enough credits, you might consider whether returning to work — even part-time — would help you reach the threshold. Each year you work and earn at least $1,730, you add one credit. However, this decision depends on your health, your ability to work, and whether working would affect any other benefits you receive.
Credits and Your Family Members' Benefits
If you are found may be able to access for SSDI, your family members may also receive benefits based on your work record. Your spouse, ex-spouse, and children can each receive a portion of your benefit amount. The number of work credits you have does not change their benefit amounts — only your own may be able to access for SSDI determines whether they can receive anything at all.
Family members have their own may be able to access rules. A spouse must be at least 62 years old (or any age if caring for a child under 16). Children must be under 19 (or 19 if still in high school full-time). An ex-spouse must have been married to you for at least 10 years and must be at least 62 years old.
Frequently Asked Questions
Do credits expire or disappear after a certain time?
Work credits do not expire once you earn them. They stay on your Social Security record permanently. However, for SSDI purposes, you must have earned at least 20 of your required credits within the 10 years before your disability began. Older credits count toward your total but not toward the recency requirement.
If I worked under different names or Social Security numbers, will those credits count?
Credits earned under a different name or number may not appear on your current record. Contact Social Security with documentation of the work (W-2 forms, pay stubs, or tax returns) and proof of your identity. Social Security can sometimes consolidate earnings records, but this process takes time and requires evidence.
Can I earn credits while receiving unemployment benefits?
No. Unemployment benefits are not wages subject to Social Security tax, so they do not generate work credits. Only earnings from employment — wages, self-employment income, or certain other types of compensation — count toward credits.
What if I worked for a government employer that did not pay Social Security taxes?
Some government employees, particularly those hired before certain dates, were not covered by Social Security. If your government employer did not withhold Social Security taxes, those years do not generate credits. You may be covered by a different pension system instead. Contact your former employer's benefits office to confirm your coverage status.
Can I check my credits before I explore for SSDI?
Yes. Create a my Social Security account at ssa.gov to view your earnings record and credit count anytime. This is the best way to know whether you meet the credit requirement before you contact Social Security about SSDI. If you spot errors, you can report them before you explore.
