SSDI Work Credits in South Dakota Explained

Social Security Disability Insurance (SSDI) provides critical financial support to South Dakota residents who become unable to work due to a qualifying disability. However, eligibility for these benefits depends heavily on your work history, specifically the number of work credits you have earned through employment covered by Social Security. Understanding how work credits function is essential for anyone considering applying for SSDI benefits in South Dakota.

How Work Credits Are Earned

Work credits represent the foundation of SSDI eligibility. The Social Security Administration uses these credits to determine whether you have worked long enough under Social Security to qualify for disability benefits. You earn credits based on your annual wages or self-employment income.

As of 2024, you earn one credit for each $1,730 in wages or self-employment income, up to a maximum of four credits per year. This threshold adjusts annually for inflation. For example, if you earn $6,920 or more in a calendar year, you automatically earn the maximum four credits for that year, regardless of when during the year you earned the income.

South Dakota workers earning credits follow the same federal standards as workers nationwide. Whether you work in agriculture, healthcare, retail, or any other industry in South Dakota, your covered employment generates these crucial credits. Self-employed individuals in South Dakota, including ranchers, farmers, and independent business owners, also earn credits when they pay self-employment taxes on their net earnings.

Work Credit Requirements for SSDI Eligibility

The number of work credits you need to qualify for SSDI depends primarily on your age when you become disabled. Generally, you need 40 credits, 20 of which must have been earned in the last 10 years ending with the year you become disabled. This is often referred to as the "recent work test."

However, younger workers in South Dakota face different requirements:

  • Before age 24: You need 6 credits earned in the 3-year period ending when your disability begins
  • Age 24 to 31: You need credits for working half the time between age 21 and the time you become disabled
  • Age 31 or older: You generally need the standard 40 credits, with 20 earned in the last 10 years

This sliding scale recognizes that younger workers have had less time to accumulate work credits. A 25-year-old worker in Sioux Falls or Rapid City who becomes disabled would not be held to the same 40-credit standard as a 45-year-old worker.

The Duration of Work Test

Beyond the recent work test, SSDI applicants must also satisfy the "duration of work test," which examines your total work history. This test ensures you have worked long enough under Social Security overall, not just recently. The required number of total credits increases with age:

  • Age 28-30: 10 credits needed
  • Age 32: 12 credits needed
  • Age 34: 14 credits needed
  • Age 42: 20 credits needed
  • Age 50: 28 credits needed
  • Age 60: 38 credits needed
  • Age 62 or older: 40 credits needed

South Dakota residents with gaps in their employment history should carefully review their work record. If you stopped working for several years to raise children, care for family members, or pursue education, you may find that your credits do not meet the recent work requirement even if you have sufficient total credits.

Special Considerations for South Dakota Workers

Certain employment situations common in South Dakota warrant special attention. Agricultural workers, who represent a significant portion of the state's workforce, must ensure their employment is covered under Social Security. While most farm employment is covered, some agricultural workers may have been employed in positions not covered by Social Security, which means those wages did not generate work credits.

Tribal members working for tribal enterprises should verify whether their employment is covered. Some tribal employment is not subject to Social Security taxes and therefore does not generate work credits. If you have worked both on and off tribal lands in South Dakota, your work credit calculation may be more complex.

Military service also affects work credits. South Dakota veterans may have earned special wage credits for military service before 1957 and from 1957 through 2001. These additional credits can help veterans meet the work requirements for SSDI even if their civilian work history alone would be insufficient.

Checking Your Work Credits and Taking Action

South Dakota residents can verify their work credits by creating a my Social Security account at ssa.gov or by requesting a Social Security Statement. This statement shows your earnings history and the number of credits you have earned. Reviewing this information before applying for SSDI helps identify any discrepancies or missing credits that need correction.

If your work credit review reveals you are short of the required credits, you have limited options. Unlike some Social Security programs, you cannot "buy" work credits. However, if you are close to meeting the requirement and your medical condition allows for some limited work activity, continuing to work while documenting your limitations might enable you to earn the additional credits needed.

Errors in your earnings record should be corrected immediately. The Social Security Administration may have incomplete records, especially for older employment or self-employment. Gather W-2 forms, tax returns, pay stubs, and other documentation proving your earnings to correct any inaccuracies in your work history.

For South Dakota residents who do not have sufficient work credits for SSDI, Supplemental Security Income (SSI) may provide an alternative. SSI does not require work credits but instead has strict income and resource limits. Many South Dakotans who cannot qualify for SSDI due to insufficient work history may still receive disability benefits through SSI.

Understanding work credits is just one component of SSDI eligibility. You must also meet Social Security's strict definition of disability and provide extensive medical evidence supporting your claim. The application process can be complex, and the majority of initial applications are denied. Having a clear understanding of your work credit status before applying helps you assess your likelihood of approval and plan accordingly.
