Applying for Social Security Disability Insurance (SSDI) is more than showing a medical condition prevents work. The Social Security Administration (SSA) also looks at work history using a system of work credits. These credits reflect contributions to Social Security through payroll taxes over the years. For Indiana residents with a disability, understanding work credits can help clarify SSDI eligibility.
The difference between SSDI and SSI
Understanding the difference between SSDI and Supplemental Security Income (SSI) is important when considering disability benefits. While SSDI requires work credits, SSI does not.
SSI is a program based on financial need for those with limited income and resources, regardless of work history. Some people may qualify for both programs at the same time. Indiana residents applying for either program must meet federal SSA requirements.
The role of work credits in SSDI eligibility
Work credits can form the basis for SSDI eligibility. The SSA uses these credits to track a person’s work history and contributions to the Social Security system through payroll taxes. Without enough work credits, even individuals with severe disabilities may not qualify for SSDI benefits.
A worker earns one credit for each $1,890 in earnings per year. The maximum number of credits in a single year is four at $7,560.
Work credit requirements based on age
The age at which a disability begins affects how many work credits are needed to qualify for SSDI. Generally, the SSA requires applicants to have 40 credits. Workers must earn 20 of those credits in the 10 years before their disability begins.
Younger workers may qualify with fewer credits. The SSA recognizes that younger workers have had less time to get credits compared to older workers. It also considers whether credits were earned recently before the disability began.
Common situations that affect work credits
Individuals who took time off to raise children, care for family members or pursue education may have gaps in their work history. Similarly, those who worked part-time or had periods of unemployment may have fewer credits than full-time workers.
Self-employed individuals also earn work credits. However, they must report their income accurately on tax returns. The SSA calculates credits based on net earnings from self-employment.
Getting help with your SSDI application
Determining SSDI eligibility can feel overwhelming, especially when dealing with a serious medical condition. In such cases, professional guidance can prepare a strong application. A thorough, well-organized submission ensures that the SSA has everything it needs to evaluate your claim.
