The basic requirement: 5 of your last 10 years

To receive Social Security Disability Insurance (SSDI), you generally need to have worked and paid Social Security taxes for at least 5 of the last 10 years. This is the most common threshold, and it applies to most people under age 31.

Those 5 years do not have to be consecutive. You could have worked 2 years, taken time off, then worked 3 more years — and that counts. What matters is that you accumulated enough work credits during that 10-year window. Each quarter you work and pay taxes, you earn up to one credit per quarter, and you need 40 credits total to ever be insured for disability benefits.

The Social Security Administration (SSA) checks your earnings record when you file. They look at what you reported to the IRS through your employer's payroll taxes, or through self-employment tax if you are self-employed. If the record shows you met the requirement, you move forward in the process.

Key Takeaways

  • Most people need 5 years of work in the last 10 years, plus 40 total work credits earned at any point in your life, to be insured for SSDI.
  • Younger workers (under 31) may need fewer credits — as few as 6 credits if you became disabled before age 24.
  • The SSA verifies your work history using your Social Security number and your tax records, so you do not need to gather pay stubs yourself.
  • If you do not meet the work requirement, you may still be able to receive Supplemental Security Income (SSI), which has no work history requirement.
  • Work credits are earned only when you pay Social Security taxes, not when you volunteer, care for family, or work off the books.

How work credits are earned and counted

A work credit is earned when you work and your employer (or you, if self-employed) pays Social Security taxes on your wages. In 2024, you earn one credit for every $1,730 in wages, up to a maximum of 4 credits per year. That amount changes slightly each year, so the threshold is different if you worked in 2020 versus 2024.

Self-employed people earn credits the same way — by paying self-employment tax on their net income. The SSA counts this automatically when you file your tax return; you do not have to report it separately to Social Security.

Work done without paying Social Security taxes does not earn credits. This includes volunteer work, caring for a family member without pay, informal or under-the-table work, and work outside the United States (with some exceptions for U.S. citizens working abroad). If you worked but your employer did not report your wages to Social Security, you can contact the SSA with documentation like pay stubs or a letter from your employer, and they can correct your record.

Younger workers and reduced work requirements

If you became disabled before age 31, you may not need the full 5 years of recent work. The SSA uses a sliding scale based on your age at the time you became unable to work.

For example, if you became disabled at age 24, you need only 6 work credits in the 3 years before your disability began — not 5 years of work. At age 26, you need 12 credits in the 4 years before disability. At age 28, you need 16 credits in the 5 years before disability. By age 31, you need the standard 40 credits with 5 of the last 10 years worked.

The SSA calculates your specific requirement based on your date of birth and the date your disability began. When you file, they will tell you whether you meet the requirement for your age group.

The 40-credit lifetime requirement

Beyond the recent work requirement, you also need 40 work credits total earned at any point in your working life. This is a separate rule from the "5 of the last 10 years" requirement — you must meet both.

If you worked steadily for 10 years at any point, you almost certainly have 40 credits. But if you had gaps in employment or worked part-time for much of your life, you may not. The SSA will show you your total credits on your Social Security statement, which you can view online at ssa.gov or request by mail.

Credits do not expire. If you earned 30 credits between ages 18 and 28, then stopped working, those 30 credits remain on your record. If you return to work later and earn 10 more credits, you now have 40 total and meet the lifetime requirement.

What happens if you do not meet the work requirement

If you do not have enough work credits or recent work history, you cannot receive SSDI. However, you may be able to receive Supplemental Security Income (SSI) instead, which is a different federal program with no work history requirement. SSI is based on financial need, not work credits.

To receive SSI, you must have limited income and resources (the limits vary by state and change each year), and you must have a disability that meets the SSA's definition. You can explore for both SSDI and SSI at the same time, and the SSA will determine which one you may receive based on your work history and finances.

If you are close to meeting the work requirement but not quite there, you might also consider whether waiting a few more months or years to file would help. If you return to work and earn additional credits, you could become insured. However, this is only an option if your disability allows you to work — and the SSA will evaluate whether any work you do is substantial gainful activity, which could affect your benefits.

How the SSA verifies your work history

You do not have to prove your work history by gathering pay stubs or employment letters. The SSA has access to your earnings record through your Social Security number. When you file for SSDI, they pull your record automatically and check it against what you reported on your process.

If there is a discrepancy — for example, you worked somewhere but it does not appear in your record — you can contact the SSA with documentation. Acceptable proof includes W-2 forms, pay stubs, a letter from your former employer on company letterhead, or a copy of your tax return. The SSA can then correct your record if the documentation supports the correction.

This process usually takes a few weeks. If you are filing for SSDI and you believe your record is incomplete, mention it when you explore. The SSA will investigate before making a decision on your case.

Work credits and your family members

Your work credits affect not only your own SSDI benefits but also what your family members may receive. If you are approved for SSDI, your spouse, ex-spouse (if married 10 years or longer), and children under 19 (or 19 if still in high school) may be able to receive benefits based on your work record.

The amount they receive depends on your Primary Insurance Amount (PIA), which is calculated from your lifetime earnings. The more you earned and the more credits you accumulated, the higher your PIA, and the higher the family benefit. However, there is a family maximum — the total amount all family members can receive together is usually 150 to 180 percent of your own benefit amount.

Frequently Asked Questions

Do I need to have worked for the same employer for 5 years?

No. Your 5 years of work can be spread across many different employers. The SSA only cares that you worked and paid Social Security taxes during those years, not where you worked or how long you stayed in each job.

If I worked outside the United States, do those years count?

Usually not, unless you are a U.S. citizen working for a U.S. employer or the U.S. government. Work done for a foreign employer in a foreign country typically does not earn Social Security credits. There are some exceptions for specific countries with Social Security agreements with the United States, so contact the SSA if you worked abroad.

Can I get SSDI if I have not worked in 15 years?

Not based on your own work record. However, you may be able to receive SSI if you have limited income and resources and meet the disability definition. You could also potentially receive benefits as a spouse or ex-spouse of someone who is insured for SSDI, if you meet the age and relationship requirements.

What if my employer did not report my wages to Social Security?

Contact the SSA with proof of your employment and earnings, such as pay stubs, W-2 forms, or a letter from your employer. The SSA can correct your record and add the credits you earned, though this process may take several weeks.

Do years I was in school or unemployed count toward the 5 years?

Only if you worked and paid Social Security taxes during those years. Time spent in school or unemployed without working does not earn credits. However, if you worked part-time while in school, those earnings do count.
