The purpose of the SNAP BACK Act of 2025 is to ensure that state agencies are financially supported when they continue to administer the Supplemental Nutrition Assistance Program (SNAP) during periods when federal funding is temporarily unavailable. This legislation aims to provide stability and assurance to both the states and the individuals relying on SNAP benefits. The key provision of the Act requires the Secretary of Agriculture to reimburse state agencies for any costs they incur while managing the SNAP program during a lapse in federal appropriations.
