Your eligibility for food stamps--a program which renamed the Supplemental Nutrition Assistance Program in 2009--is based on how many people live and cook together in your home, the amount of your monthly expenses and how much money comes into your home. You must provide proof of both earned and unearned income when you apply to be considered, and there are many different types of paperwork you can bring as proof.
Earned income includes any sort of income you work for, such as wages, tips and salary. Any proof of earned income cannot be more than four weeks old at the time of your application, according to GettingSNAP.org. Proof of income usually means a pay stub, but you also can get your employer to furnish a written statement of how much you've earned over the past four weeks before taxes.
Unearned income includes sources such as Supplemental Security Income, Social Security payments, child support payments, disability assistance and unemployment payments, according to the Social Security Administration. Bring proof of any of these payments, which can include a copy of an award letter or a copy of a payment check.
Proving your income when you self employed can be tough, but the SNAP program makes it easy. If you're self employed, instead of having to furnish weekly pay stubs, you only need to provide a copy of your latest tax return, according to GettingSNAP.org. Your tax return must show at least three months worth of self-employment income. Bring in the Schedule C Form.
Your allotment amount is the term for the money you can get each month for food, depending upon your need and the number of people in your home. The maximum starts at $200 for a one-person family and goes up for larger families, according to the U.S. Department of Agriculture.
