Social Security will consider all assets a person has and all income available in a household in calculating whether someone qualifies for SSI or if there is a reduction. Each state has different income standards so I will not be able to comment on Arkansas standards, but most likely the problem is that the $900 i over and above what can be earned in a household without a reduction of SSI benefits. Supplemental Security Income is a needs based program -- you have to not olny be disabled, but not have assets/income above a certain level. Social Security Disability Income on the other hand is a disability program that workers pay in based on their wages and have to be medically qualified to draw benefits.
