US SB3583

Establishes a 5-year pilot program allowing up to 5 states to consolidate funding from multiple federal antipoverty programs—including SNAP, TANF, child care subsidies, LIHEAP, housing assistance, and workforce programs—into single "Upward Mobility Grants" administered by HHS

Requires participating states to design benefit structures that limit Marginal Effective Tax Rates to no more than 50% to reduce benefit cliffs, with priority given to applications demonstrating strongest work incentives and employment outcome improvements

Mandates SNAP work requirements apply to pilot participants and requires states to implement program integrity measures including fraud prevention, data privacy protections, and clear auditable records

Requires independent third-party evaluations measuring upward mobility outcomes including employment rates, earnings increases, poverty reduction, and decreased dependence on direct assistance, using rigorous experimental designs with random assignment preferred

Grants states broad waiver authority from statutory and regulatory requirements related to eligibility, program design, and funding allocation, while prohibiting waivers for civil rights protections, labor standards, health and safety, environmental protections, and religious freedom provisions
