An applicant's total gross income received on a regular basis, such as monthly or quarterly, is added together. Some examples of income are: Social Security benefits, Veteran's benefits, pensions, annuities, and interest income.
A recent law allowed the exclusion of income money if the income money is placed in an income qualifying trust, called a Miller Trust. This trust allows those persons who are over the current Medicaid income limit to set up a trust so that they are then income eligible. These trusts must be irrevocable, and you would need to contact a lawyer before beginning the application process for Medicaid.
