DCF’s payment error rate exceeded federal standards in fiscal years 2023 and 2024 for multiple reasons including high staff turnover, the complexity of the SNAP eligibility rules, and inconsistent verification efforts. The Supplemental Nutrition Assistance Program (SNAP) is a federal program that provides monthly funds to low-income families to buy food. Individuals must submit an application and provide extensive financial and other information to the Department for Children and Families (DCF) to qualify for SNAP benefits. DCF takes several steps to process and verify each application. The SNAP benefit eligibility determination is complex, and errors can occur at many points. The federal government monitors states’ SNAP benefit payments to ensure accuracy. DCF’s SNAP payment error rate has exceeded the federal payment error rate threshold of 6% since 2019. In the 2 years we reviewed, most of the nearly 300 errors that contributed to the payment error rate were related to miscalculating an applicant’s income and resources. Staff turnover, the complexity of SNAP eligibility rules, and inconsistent verification efforts appear to be significant factors in the department’s SNAP payment errors. DCF told us modifications to KEES might reduce SNAP payment errors but it’s unclear how much impact additional actions might have. Across the 2 years we reviewed, we identified several hundred additional errors that were not included in the federal payment error rate because the dollar value of the error was less than the federal reporting threshold. Last, changes in federal law could result in the state paying for a larger share of SNAP costs.
