What Work Credits Are and Why They Matter

Work credits are the record Social Security keeps of your earnings over time. To receive SSDI (Social Security Disability Insurance), you must have earned enough work credits before you became disabled. Unlike SSI, which is based on financial need, SSDI is based on your own work history—you cannot receive it without having worked and paid Social Security taxes.

You earn one work credit for every $1,550 you earn in a year (this dollar amount changes each year, so the threshold will be different in 2024 or 2025 than it was in 2020). You can earn a maximum of four work credits per year, regardless of how much you earn. This means you need to work in at least 10 calendar years to accumulate the 40 credits most people need for SSDI.

The Social Security Administration (SSA) counts only earnings on which you paid Social Security tax. Self-employment income counts, as does W-2 wage income. Cash payments, informal work, or income from sources other than employment do not count toward work credits.

Key Takeaways

  • You need 40 work credits total, earned over at least 10 different calendar years, to meet the work credit requirement for SSDI.
  • You earn one credit for every $1,550 you earn in a year (the threshold amount changes annually), with a maximum of four credits per year.
  • Only earnings subject to Social Security tax count—wages from a job, self-employment income, and farm income all count, but cash payments and informal work do not.
  • The SSA has a record of your earnings on file; you can check your work credit count by creating a my Social Security account online or requesting a statement by mail.
  • If you do not have 40 credits, you may still be able to receive SSI (Supplemental Security Income) if your income and resources are low enough, though SSI is a different program with different rules.

How to Check Your Current Work Credit Count

The fastest way to see how many work credits you have is to log into your my Social Security account at ssa.gov. You will need to create an account using your Social Security number, email address, and a password. Once logged in, you can view your earnings record and see exactly how many credits you have accumulated and in which years you earned them.

If you do not want to create an online account, you can request a paper statement by mail. Call the SSA at 1-800-772-1213 (TTY 1-800-325-0778) and ask for a Statement of Earnings. The SSA will mail it to you within two weeks. This statement shows your earnings year by year and your total work credit count.

Check your record carefully. If you see missing earnings or years where you worked but no credits appear, you can file a correction with the SSA. Bring W-2 forms, tax returns, or pay stubs as proof. The SSA has a limited time window to correct old records, so do not delay if you spot an error.

Work Credits for People Who Became Disabled Young

If you became disabled before age 24, you do not need 40 work credits. Instead, you need only six credits earned in the three-year period before you became disabled. This is called the recent work requirement. You still earn credits the same way—one credit per $1,550 earned in a calendar year, up to four per year—but the timeline is much shorter.

If you became disabled between ages 24 and 31, you need credits equal to half the time between age 21 and the age you became disabled, with a minimum of six credits. For example, if you became disabled at age 28, you would need credits for 3.5 years of that seven-year span, which rounds to four credits.

After age 31, the standard 40-credit rule applies. The SSA will calculate which rule benefits you most and use that one.

What Happens If You Do Not Have Enough Work Credits

If you do not have 40 work credits and you are over 31, you cannot receive SSDI based on your own work record. However, you may be able to receive benefits as a family member of someone who is receiving or may have access to to SSDI. A spouse, ex-spouse, or adult child of a disabled worker can sometimes receive benefits on that person's record, even if they have no work credits of their own.

You may also be able to receive SSI (Supplemental Security Income) instead. SSI does not require work credits at all. Instead, it is based on your current income and resources. If you have a disability, are blind, or are 65 or older, and your monthly income is below a certain limit (which varies by state), you may be able to receive SSI. The income and resource limits are much stricter than SSDI, but SSI requires no work history.

If you are close to having enough credits—for example, you have 38 credits and are still working—you may want to continue working long enough to earn two more credits before you file. This is a decision to make with a representative who knows your full situation, because working can affect your disability status in other ways.

How Work Credits Affect Your Benefit Amount

Work credits determine whether you can receive SSDI, but they do not determine how much you receive. Your monthly benefit amount is based on your Primary Insurance Amount (PIA), which is calculated from your average earnings over your highest-earning 35 years. The more you earned during those years, the higher your benefit.

This means that having exactly 40 credits and having 50 credits results in the same may be able to access—but your earnings history determines the payment. A person with 40 credits and high earnings will receive more than a person with 40 credits and low earnings.

If you worked for many years but some years had very low earnings, those low-earning years still count in the 35-year average. The SSA drops your five lowest-earning years from the calculation, but years with zero earnings (years you did not work) count as zero and cannot be dropped.

Reporting Work Credits When You File for SSDI

When you file for SSDI, you do not need to submit proof of your work credits. The SSA already has your earnings record from your tax returns and your employer's reports. However, you should bring documents that show your work history in case there are gaps or errors in the SSA's record.

Bring recent W-2 forms, tax returns, or pay stubs. If you are self-employed, bring copies of your tax returns for the past several years. If you worked for an employer that no longer exists or you cannot locate your documents, the SSA can often verify your earnings through its own records or through the IRS.

If the SSA's record shows fewer credits than you believe you earned, you can dispute it during the filing process. Provide whatever documentation you have. The SSA will investigate and correct the record if your evidence supports it.

Frequently Asked Questions

Can I earn work credits after I become disabled?

No. Work credits must be earned before the month you become disabled. Once the SSA determines your disability onset date, no credits earned after that date count toward SSDI. However, if you return to work while receiving SSDI, you may be able to continue receiving benefits for a trial period under the Ticket to Work program.

Do I need to have worked in the last year to get SSDI?

Not necessarily. You need 40 work credits earned over at least 10 different years, but those years do not have to be recent. However, if you became disabled before age 31, you do need recent work credits (six credits in the three years before disability). The SSA will tell you which rule applies to you.

What if I worked in another country?

Work performed outside the United States generally does not count toward Social Security work credits, with limited exceptions for U.S. citizens working for the U.S. government or certain international organizations. If you worked abroad, contact the SSA to find out whether your specific situation qualifies.

Can my spouse's work credits help me get SSDI?

No. SSDI is based on your own work record only. However, if your spouse is receiving or may have access to to SSDI, you may be able to receive benefits as a spouse on their record, regardless of your own work history. This is a different benefit from SSDI on your own record.

What if I have a gap in my work history?

Gaps in your work history do not prevent you from earning work credits. You earn credits based on what you earned in each year you worked, not on whether you worked every year. As long as you have 40 credits spread across at least 10 different calendar years, the gaps do not matter for SSDI purposes.
