At our initial meeting with clients who are denied Social Security benefits, we are often asked why Social Security sent two copies of the same denial letter. Although the letters appear to be the same, they actually pertain to different benefits. When you apply for disability benefits, you apply for two types of benefits: (1) Social Security Disability and (2) Supplemental Security Income (SSI).
Social Security Disability benefits are based upon the work credits that you earn each year in which Social Security taxes are deducted from your paycheck. Supplemental Security Income (SSI) benefits is based upon your financial need. In both cases, Social Security will determine whether you medically are disabled, but with SSI, Social Security will also determine whether you meet the financial requirements to be eligible for benefits.
