How long do I have to work to apply for SSDI? To be eligible for Social Security Disability Insurance (SSDI), you must have worked and paid Social Security taxes for a certain period. This requirement is measured in work credits, which are earned based on your annual earnings. Generally, you need about 20 work credits in the last 10 years, but the exact number depends on your age at the time you become disabled. Understanding how long you must work is crucial for meeting the SSA’s eligibility rules and successfully applying for SSDI benefits.

Please answer a few questions to help us determine your eligibility.


Understanding Work Credits for SSDI

Work credits are earned by:

  • Paying Social Security taxes through employment or self-employment.
  • Credits accumulate based on your yearly amount of earnings.
  • You can earn up to 4 credits per year, depending on income.
Basic Eligibility Timeframe

The SSA requires:

  • You to have earned roughly 20 credits within the past 10 years before your disability began.
  • Younger applicants may need fewer credits based on age.
  • The number of credits needed generally increases with age.
Age-Related Credit Requirements

Depending on your age when disabled:

  • If you become disabled before age 24, you may only need 6 credits earned in the last 3 years.
  • Applicants 24-31 typically need credits for half the years between age 21 and the disability onset.
  • Those over 31 usually require around 20 credits in the last 10 years.
Special Rules for Younger Workers

Younger workers with less work history might:

  • Qualify with fewer work credits if they meet disability duration requirements.
  • Still need to have paid into Social Security through employment.
Why Work History Matters

The SSA uses your work history to:

  • Evaluate if you have paid sufficient Social Security taxes to qualify.
  • Determine the amount of benefits based on your past earnings.
Common Challenges

Applicants often face issues such as:

  • Counting insufficient work credits to meet the minimum.
  • Confusion about how past employment years count toward eligibility duration.
  • Needing documentation of earnings and employment history for SSA verification.
