The Work Credit Requirement for SSDI

To receive Social Security Disability Insurance (SSDI), you must have earned enough work credits through payroll taxes. The number you need depends on your age when your disability began. Most people need between 20 and 40 credits, with the exact amount tied to how old you were when you became unable to work.

Work credits are not the same as years worked. You earn one credit for every $1,550 of wages you report to Social Security in a calendar year (this dollar amount changes annually). You can earn a maximum of four credits per year, regardless of how much you earn. This means you cannot bank extra credits by working more in a single year.

The Social Security Administration (SSA) checks your earnings record when you file for SSDI. They count back from the year you became disabled to see whether you have enough credits to meet the requirement for your age group.

Key Takeaways

  • You earn one work credit for every $1,550 of reported wages in a calendar year, with a maximum of four credits per year.
  • Most SSDI applicants need 20 to 40 work credits, depending on their age when the disability began.
  • The SSA automatically reviews your earnings record when you file; you do not need to calculate credits yourself.
  • If you do not have enough credits, you may still be able to receive Supplemental Security Income (SSI) based on financial need instead.

Work Credit Requirements by Age

The SSA uses age brackets to determine how many credits you need. If you became disabled before age 24, you need only six credits earned in the three years before your disability began. This is the lowest threshold and reflects that younger workers have had less time to build a work history.

If you became disabled between ages 24 and 30, 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 roughly 3.5 years of work.

If you became disabled at age 31 or older, you need 20 credits. This is the most common requirement. Twenty credits typically means you worked and paid Social Security taxes for at least five years, though not necessarily five consecutive years.

The SSA publishes a detailed chart showing exact credit requirements for each age. You can request a copy from your local Social Security office or view it on the SSA website.

How the SSA Counts Your Work Credits

The SSA pulls your earnings record from your Social Security account. Every time you work and your employer withholds Social Security tax, that wage gets reported to Social Security under your Social Security number. Self-employed workers report their earnings when they file taxes.

The SSA counts credits based on the calendar year in which you earned the wages, not the year you reported them. If you earned $6,200 in 2023, you would receive four credits for 2023 (the maximum), even if you did not report those earnings until 2024.

Credits do not expire. If you earned 15 credits between 2010 and 2015 and then stopped working, those credits remain on your record. If you return to work later and earn more credits, they add to your total.

What Happens If You Do Not Have Enough Credits

If you do not have enough work credits for SSDI, you cannot receive SSDI benefits based on your own work record. However, you may be able to receive Supplemental Security Income (SSI) instead, which is a needs-based program that does not require work credits. SSI is available to disabled people with limited income and resources, regardless of work history.

You may also be able to receive benefits as a family member on someone else's work record. If your spouse, parent, or adult child has enough credits and is receiving SSDI or Social Security retirement benefits, you may be able to claim benefits based on their record. This is called a "deemed" claim and has different rules than claiming on your own record.

If you are close to having enough credits, you might consider returning to work temporarily to earn the remaining credits you need. Even part-time work can generate credits if your earnings meet the annual threshold. The SSA can tell you exactly how many more credits you need.

Checking Your Work Credit Record

You can view your work credits and earnings record by creating a my Social Security account on the SSA website. Log in and select "Earnings Record" to see the wages reported for each year and the credits you have earned. This is free and takes about 10 minutes.

You can also request a paper copy of your earnings record by calling Social Security at 1-800-772-1213 or visiting your local Social Security office in person. Bring your Social Security card and a photo ID. The SSA will mail you a statement showing your credits and earnings history within two weeks.

If you see errors in your earnings record—wages you earned but that do not appear, or wages attributed to you that you did not earn—report them to Social Security when ready. Errors can delay your SSDI decision or reduce your benefit amount. You have a limited window to correct errors, so do not wait.

Work Credits and Your Benefit Amount

Work credits determine whether you can receive SSDI, but they do not determine how much you receive each month. Your monthly benefit amount is based on your Primary Insurance Amount (PIA), which is calculated from your average earnings over your lifetime. Higher lifetime earnings result in a higher monthly benefit.

This means that having exactly 20 credits and having 40 credits both make you may be able to access for SSDI, but the person with higher lifetime earnings will receive a larger monthly check. The SSA calculates your PIA automatically when you file.

Frequently Asked Questions

Can I earn work credits while receiving SSDI?

Yes. If you return to work while receiving SSDI, you continue to earn work credits. These credits do not affect your current SSDI benefits, but they can increase your benefit amount if your new earnings are higher than your previous average earnings. The SSA recalculates your benefit annually.

Do I need to have worked recently to get SSDI?

Not necessarily. If you have enough total credits, the SSA does not require that you earned them recently. However, if you became disabled before age 31, you must have earned credits within a specific time window before your disability began. For older workers, credits earned decades ago still count.

What if I worked in another country?

Work performed in another country generally does not count toward Social Security credits unless you were a U.S. citizen or resident alien working for a U.S. employer. Some countries have agreements with the United States that allow work credits to transfer. Contact Social Security to discuss your specific situation.

Do military service credits count toward SSDI?

Yes. If you served on active duty in the U.S. military before 1968, you receive deemed wage credits. From 1968 onward, military service counts only if you paid Social Security taxes on your military pay. The SSA automatically includes military credits in your record if you are may be able to access.

How often does the annual credit amount change?

The dollar amount needed to earn one work credit changes each year based on average wage growth. In recent years it has increased by $50 to $150 annually. The SSA announces the new amount in October for the following calendar year. This change does not affect credits you have already earned.
