The basic requirement: 10 years of work in the last 15 years

To receive Social Security Disability Insurance (SSDI), you generally need to have worked and paid Social Security taxes for at least 10 years (40 work credits) in the 15 years before you become unable to work. This is the most common path to SSDI may be able to access.

The exact timing matters. Social Security counts backward from the year you stop working due to disability. If you stopped working in 2024, the agency looks at whether you earned enough credits between 2009 and 2024. You do not need those 10 years to be consecutive — gaps are fine as long as you have 40 credits within that 15-year window.

The work does not have to be full-time. Part-time jobs, self-employment, and seasonal work all count toward your credits. What matters is that you paid Social Security taxes on your earnings, which happens automatically for most employees and self-employed people.

Key Takeaways

  • You need 40 work credits, which typically means 10 years of work in the 15 years before you become unable to work.
  • One work credit requires you to earn a certain amount in a calendar year; in 2024, you earn one credit for each $1,730 in wages (the amount changes yearly).
  • You can earn up to four credits per year, so you cannot earn 40 credits in a single year no matter how much you earn.
  • If you became disabled before age 31, you may need fewer credits — as few as six credits earned in the three years before disability.
  • Your work history is verified through your Social Security record, which you can review for free at ssa.gov.

How work credits are earned and counted

A work credit is not the same as a year of work. You earn one credit for each amount of earnings you report to Social Security in a calendar year. In 2024, you earn one credit for every $1,730 you earn; in 2023, it was $1,640. The dollar amount increases most years to keep pace with wage growth.

You can earn a maximum of four credits per year, no matter how much you earn. This means you cannot compress 10 years of work into five years by earning double. If you earned $6,920 in 2024, you would receive four credits for that year — the maximum — even though you earned enough for more if the system worked that way.

Self-employed people count the same way. Your net profit from self-employment (after business expenses) is what counts toward credits. You still pay Social Security taxes on that income, and those taxes generate credits just as an employee's wages do.

Younger workers and reduced credit requirements

If you became unable to work before age 31, you do not need 10 years of work history. The requirement drops based on your age at the time of disability.

If you were between 24 and 30 when you became disabled, you need six credits earned in the three years when ready before disability. If you were 21 to 23, you need six credits earned in the one-year period before disability. If you were under 21, you need only six credits earned in the three-year period ending when you became disabled — and those credits do not have to be recent.

These younger-worker rules exist because someone who has worked since age 16 or 17 may not yet have accumulated 10 years of work history. The rules recognize that a teenager or young adult who becomes disabled should not be locked out of SSDI straightforward because they have not had time to build a full work record.

How Social Security verifies your work history

Social Security maintains a record of your earnings and work credits based on what your employers (or you, if self-employed) report to the Internal Revenue Service. You do not have to submit pay stubs or employment letters unless Social Security questions your record.

You can view your own work history for free by creating an account at ssa.gov and accessing your Social Security Statement. This shows the credits you have earned each year and your total to date. Checking this before you explore for SSDI is wise — if there are errors or missing years, you can request a correction while you still have time.

If you find gaps or missing credits, you can ask Social Security to investigate. Bring W-2 forms, pay stubs, or tax returns as proof. Self-employed people should have their tax returns. The agency can sometimes add credits that were not originally reported, though there are time limits on how far back corrections can go.

Work credits and your family members

Your work credits determine your own SSDI benefit amount, but they also matter for your family. If you are approved for SSDI, your spouse and unmarried children under 19 (or 19 if still in high school) may be able to receive benefits based on your work record. The more credits you have, the higher your benefit amount, and the higher the family benefits tied to your record.

Your family members do not need their own work history to receive these benefits. They are paid from your SSDI benefit, which is calculated from your earnings record and work credits. This is different from their own potential SSDI claims — they would need their own work history to claim SSDI as disabled workers themselves.

What happens if you do not have enough work credits

If you do not meet the work credit requirement, you cannot receive SSDI. Social Security will deny your claim based on insufficient work history. This is a permanent bar unless your situation changes — for example, if you return to work and earn more credits, or if you were denied as a young adult and later meet the age-based requirements.

If you do not have enough credits for SSDI but you are over 62, you may be able to receive Supplemental Security Income (SSI) instead, which is a needs-based program that does not require work history. SSI has different rules and lower benefit amounts, but it can provide income if you meet the financial and disability requirements.

Some people who do not may have access to for SSDI may also have a claim through a family member's work record — for example, as a widow or widower, or as a dependent child. These are separate from SSDI based on your own work history.

Frequently Asked Questions

Do I need 10 consecutive years of work, or can there be gaps?

Gaps are fine. You need 40 credits in the 15 years before disability, but those credits do not have to be earned year after year. You could work five years, take five years off, then work five more years and still meet the requirement if you have 40 credits total within the 15-year window.

If I worked part-time, do I still earn work credits?

Yes. Part-time work counts the same as full-time work. You earn one credit for each $1,730 you earn in 2024 (the amount varies by year), regardless of whether you worked 10 hours a week or 40 hours a week. You can earn up to four credits per year at any hours.

What if I worked in another country before moving to the US?

Work outside the US generally does not count toward SSDI credits unless you were a US citizen or resident alien at the time. Some countries have agreements with the US that allow work credits to be combined, but this is complex and depends on your citizenship and the specific country. Contact Social Security directly to discuss your situation.

Can I earn work credits after I become disabled?

No. Social Security counts your work credits only up to the month you become unable to work. Work or earnings after that date do not add credits to your SSDI record. However, if you return to work while receiving SSDI, you may be able to continue benefits under work incentive programs.

How do I know if my work credits are correct?

Create a free account at ssa.gov and view your Social Security Statement. It shows your credits by year. If you see missing years or incorrect amounts, contact Social Security with proof like W-2 forms or tax returns. Corrections can usually be made within a certain time frame, so check early.
