A work credit is a record that you worked and paid Social Security taxes in a given quarter

A work credit is not money. It is a unit of proof that the Social Security Administration uses to verify you worked and paid into the system. You earn one work credit for each quarter (three-month period) in which you earned at least a certain amount of wages and paid Social Security tax on them. In 2024, you earn one work credit for each $1,680 in covered earnings in a quarter. That threshold changes each year.

The Social Security Administration tracks these credits automatically through your employer's tax filings and your own self-employment tax returns. You do not explore for them or do anything to "set up" them. They appear on your Social Security record whether you know about them or not.

The reason work credits matter for SSDI is straightforward: the program is insurance, not welfare. You must have paid into it long enough and recently enough to be covered. Work credits are how the government measures that. Without enough of them, you cannot receive SSDI, no matter how disabled you are.

Key Takeaways

  • You earn one work credit per quarter for each $1,680 in covered earnings (the dollar amount changes yearly).
  • You can earn a maximum of four work credits per year, one per quarter, even if you earn much more than the threshold.
  • SSDI requires you to have earned enough credits overall and to have earned credits recently enough—the exact number depends on your age when you become disabled.
  • Work credits are recorded automatically by Social Security based on your tax filings; you do not need to request them or prove them yourself.
  • If you have not worked enough quarters to earn the required credits, you cannot receive SSDI, but you may be able to receive Supplemental Security Income (SSI) instead.

How many work credits you need depends on your age

The Social Security Administration uses a formula based on your age at the time you become disabled. Generally, you need between 20 and 40 work credits total, depending on when your disability began. The younger you are, the fewer credits you typically need—but you also need to have earned them more recently.

If you become disabled at age 24, you need only 6 credits earned in the three years before your disability began. If you become disabled at age 31, you need 20 credits total, with at least half earned in the 10 years before your disability began. If you become disabled at age 62 or older, you need 40 credits total, with at least 20 earned in the 10 years before your disability began.

The Social Security Administration publishes a detailed chart showing the exact requirement for each age. You can request a statement of your earnings record and current credit count from your my Social Security account online, or by calling 1-800-772-1213 and asking for a Social Security Statement.

You can earn only four work credits per year, no matter how much you earn

Even if you earn $100,000 in a single quarter, you still earn only one work credit for that quarter. The maximum is four credits per year—one per quarter. This means that if you work part-time or seasonally, you may earn fewer than four credits in a year, and it may take you longer to build up the total you need.

Conversely, if you work full-time and earn well above the quarterly threshold, you are not "wasting" earnings by earning more. The extra money does not translate to extra credits, but it does increase your Primary Insurance Amount (PIA)—the dollar amount of your monthly SSDI payment if you are approved. Higher lifetime earnings mean a higher monthly benefit.

The earnings threshold changes every year

The amount you must earn in a quarter to receive one work credit is adjusted each January based on the national average wage index. In 2023, the threshold was $1,640 per quarter. In 2024, it rose to $1,680. In 2025, it will likely be higher again, though the exact figure is not set until late in the previous year.

This annual adjustment means that the cost of earning a credit rises slightly each year, but it also means that wages keep pace with inflation. If you are working, your wages are likely rising too, so the threshold remains roughly proportional to what workers actually earn.

Self-employment income counts toward work credits

If you are self-employed, you must pay self-employment tax (Social Security and Medicare tax on your net business income) to earn work credits. The threshold is the same: you need at least $1,680 in net self-employment income in a quarter to earn one credit in 2024.

Self-employed people often file taxes once a year rather than quarterly, so you may earn all four credits in a single tax year if your annual net income is high enough. The Social Security Administration counts your net self-employment income (after deducting the self-employment tax itself) toward the quarterly thresholds, so keep careful records of your business income and expenses.

Work credits do not expire, but recency matters

A work credit you earned 20 years ago still counts toward your total. However, the SSDI rules require that you have earned credits recently as well as overall. For most people under 62, you must have earned at least half your required credits in the 10 years before your disability began. This "recency" rule ensures that SSDI covers people who have been in the workforce recently, not only those who worked long ago.

If you stopped working 15 years ago and then became disabled, you might have enough total credits but not enough recent credits, and you would not be approved for SSDI. However, you might be able to receive Supplemental Security Income (SSI) instead, which does not require work credits.

If you do not have enough work credits, SSI may be an option

Supplemental Security Income (SSI) is a separate program that does not require work credits. Instead, it requires that you have limited income and resources (less than $2,000 in countable resources for an individual, as of 2024). SSI is means-tested, meaning your own money and assets matter, whereas SSDI does not care how much you have saved.

If you do not have enough work credits for SSDI but you meet the disability standard and have low income and resources, you can pursue SSI. You can also pursue both programs at the same time—the Social Security Administration will evaluate you for both. Many people receive both SSDI and SSI simultaneously, though the total payment is usually capped at the federal SSI rate.

Frequently Asked Questions

Can I check how many work credits I have right now?

Yes. Create a free account at ssa.gov/myaccount and view your earnings record and work credit count. You can also call 1-800-772-1213 and request a Social Security Statement by mail, though this takes longer. Your record shows credits earned in each year and your total to date.

If I work part-time, will I earn fewer work credits?

Not necessarily. You earn one credit per quarter if you earn at least $1,680 in that quarter, regardless of whether you work part-time or full-time. If you earn $1,680 in one month and then stop working, you still earn one credit for that quarter. If you earn $1,680 spread across three months, you earn one credit. The timing does not matter—only the total per quarter.

What happens if I become disabled before I turn 22 and have never worked?

You may be able to receive benefits as a disabled adult child on your parent's Social Security record, rather than on your own work record. This is called a "disabled adult child" (DAC) benefit and does not require your own work credits. You must have become disabled before age 22 and your parent must be retired, disabled, or deceased.

Do volunteer hours or unpaid work count toward work credits?

No. Only work for which you paid Social Security tax counts. Volunteer work, family business work without formal wages, and work "off the books" do not generate work credits. Your employer must report your wages to the Social Security Administration for the credits to be recorded.

If I earned work credits in another country, do they count?

Generally, no—unless you worked for the U.S. government or a U.S. employer abroad. However, some countries have totalization agreements with the United States that allow work credits earned in those countries to count toward U.S. Social Security benefits. Ask the Social Security Administration whether your country has such an agreement.
