The basic timeline: work credits and time in the workforce

You need a certain number of work credits to may have access to for SSDI, and how many you need depends on your age when you become unable to work. Social Security counts work credits based on your earnings history, not on how long you've held a job. You earn one credit for each $1,470 of wages you make in a year (this dollar amount changes each year, so the exact figure varies). You can earn a maximum of four credits per year, no matter how much you earn.

Most people need between 20 and 40 work credits total to may have access to for SSDI. If you became disabled before age 24, you may need as few as 6 credits. If you're between 24 and 31, you typically need credits equal to the number of years from age 21 to your current age, up to a maximum of 20 credits. If you're 31 or older, you generally need 40 credits, with at least 20 of them earned in the 10 years before you became disabled.

The time it takes to accumulate these credits depends entirely on your work history and earnings. If you work full-time at any wage level, you'll earn four credits per year. At that pace, you could earn 40 credits in 10 years of steady work. However, if you've worked part-time, had gaps in employment, or earned below the credit threshold in some years, it will take longer to reach the required number.

Key Takeaways

  • You need between 6 and 40 work credits depending on your age, with most people needing 20 to 40 total.
  • You earn one credit for each $1,470 of annual earnings (adjusted yearly), up to four credits per year maximum.
  • At full-time work, you can earn 40 credits in approximately 10 years, but part-time work or employment gaps will extend this timeline.
  • Social Security looks at your most recent 10 years of work to verify you have current work history, not just old credits from decades ago.
  • You can check your exact work credit count by creating a my Social Security account or requesting a Statement of Earnings from Social Security.

Why recent work matters as much as total credits

Having enough total work credits is only half the requirement. Social Security also requires that your work be recent. This is called the "recency test," and it's separate from your total credit count. For most people under 31, you need to have earned at least half your required credits in the 10 years when ready before you became disabled. For people 31 and older, you need at least 20 credits earned in the 10 years before disability.

This means you cannot straightforward work for 10 years in your twenties and then stop working, even if you accumulated 40 credits. If you become disabled at age 50 without having worked in the past 10 years, you will not meet the recency requirement, and you will not may have access to for SSDI. Social Security wants evidence that you were recently part of the workforce, not that you worked a long time ago.

The recency requirement is why people who took time out of the workforce for caregiving, education, health issues, or other reasons may find themselves short on credits even if they worked steadily before the break. If you're explore for SSDI and you have a gap in your work history, Social Security will look at whether you have enough recent credits to meet the test.

How to find out how many credits you have

You don't have to guess or count your own credits. Social Security maintains a record of every credit you've earned based on your tax returns and W-2 forms. The fastest way to see your work credit count is to create a my Social Security account at ssa.gov. Once you log in, you can view your earnings record and see exactly how many credits you've earned each year.

If you don't want to create an online account, you can request a Statement of Earnings by mail. Fill out Form SSA-7050-F and send it to your local Social Security office, or call 1-800-772-1213 to request one by phone. Social Security will mail you a document showing your earnings history and your current work credit total. This usually takes two to four weeks.

When you review your earnings record, check it for accuracy. If you see years where you worked but Social Security shows no earnings, or if the amounts look wrong, contact Social Security right away. Errors in your earnings record can lower your credit count and reduce your future benefit amount. You have a limited window to correct these errors, so don't wait if something looks off.

What happens if you don't have enough credits yet

If you're disabled now but don't have enough work credits to may have access to for SSDI, you have a few options. First, if you're able to work even part-time, continuing to work will add credits to your record. Each year you work and earn above the credit threshold, you add up to four more credits. Even a few months of part-time work can sometimes make the difference.

Second, you might be able to receive Supplemental Security Income (SSI) instead of SSDI. SSI is a needs-based program that does not require work credits. It's available to disabled people with limited income and resources, regardless of work history. The monthly payment is usually lower than SSDI, and it comes with different rules about what you can own and earn, but it's an option if you don't meet SSDI's work credit requirement.

Third, if you're waiting to accumulate more credits, you can still file for SSDI now. Social Security will review your case, and if you're denied because of insufficient credits, you can appeal or reapply later once you've earned more credits. There's no penalty for filing early, and the date you file can affect when your benefits begin if you eventually may have access to.

How work credits work if you're self-employed

If you're self-employed, you earn work credits the same way as W-2 employees: one credit for each $1,470 of net self-employment income (the amount varies yearly). You can still earn a maximum of four credits per year. However, self-employed people must report their income on Schedule C of their tax return, and Social Security pulls your credit information from your tax records.

This means if you underreport income or don't file tax returns, Social Security won't count that income toward your work credits. If you're self-employed and planning to explore for SSDI, make sure your tax returns accurately reflect your earnings. If you've had years where you worked but didn't file taxes, you may need to file amended returns to get those credits added to your record.

Self-employed people should also be aware that if they continue working while receiving SSDI, their earnings will be tracked carefully. SSDI has rules about how much you can earn while still receiving benefits, and self-employment income counts toward those limits.

The difference between work credits and benefit amount

Work credits determine whether you can receive SSDI at all. Once you have enough credits, a separate calculation determines how much your monthly benefit will be. Your benefit amount is based on your Primary Insurance Amount (PIA), which is calculated from your average earnings over your entire working life. The more you earned and the longer you worked, the higher your benefit will be.

This is why having exactly 40 credits is not the same as having a high benefit. Someone who worked 10 years at high wages might have 40 credits and receive a larger monthly payment than someone who worked 30 years at low wages and also has 40 credits. Social Security looks at your lifetime earnings average, not just whether you crossed the credit threshold.

If you're concerned about your future benefit amount, you can see an estimate on your my Social Security account. The estimate shows what your SSDI payment would be if you became disabled today, based on your current earnings record. Keep in mind that this is an estimate and will change if you continue working and earning more credits.

Frequently Asked Questions

Can I get SSDI if I haven't worked in five years but I have 40 credits?

Not automatically. You need both enough total credits and recent work history. If you're 31 or older, you need at least 20 of your 40 credits earned in the 10 years before you became disabled. If you haven't worked in five years, you likely don't meet the recency requirement. However, if you earned 20 credits in the five years you did work, you may still may have access to depending on when your disability began.

How much do I need to earn each year to get four work credits?

In 2024, you need to earn $1,470 per quarter (three-month period) to earn one credit, for a total of $5,880 per year to earn all four credits. This amount increases slightly each year. You don't have to earn it evenly throughout the year—you could earn all $5,880 in one month and still get four credits for that year.

If I worked under the table and didn't pay taxes, can I still get SSDI credits?

No. Social Security bases work credits on your official earnings record, which comes from tax returns and W-2 forms. Work you did without reporting it to the IRS will not count toward your credits. If you're planning to explore for SSDI, you'll need documented work history.

Do military service years count as work credits?

Military service before 1968 may count as work credits under certain conditions. If you served on active duty before 1968, you may receive credits for that service even if you didn't pay Social Security taxes. Contact Social Security directly to learn about your military service qualifies, as the rules vary by service dates and branch.

What if Social Security says I have the wrong number of credits on my record?

Request a detailed Statement of Earnings and review it carefully against your own tax records and W-2s. If you find errors, file a Request for Correction of Earnings Record (Form SSA-7050-F4) with Social Security. You generally have three years, three months, and 15 days from the end of the year in which you earned the income to correct errors, though some exceptions exist.
