The main purpose of this legislation is to amend the Food and Nutrition Act of 2008. It aims to ensure that certain types of income, specifically those resulting from cost of living adjustments and supplementary payments, do not count when determining eligibility and benefits for the Supplemental Nutrition Assistance Program (SNAP). This change is intended to help individuals and families who rely on these benefits by preventing their assistance from being reduced due to increases in their income from these adjustments.
