A sweeping overhaul of the federal food stamp program is set to shift billions of dollars in costs onto state governments beginning in fall 2027, putting the fiscal future of SNAP in question for tens of millions of Americans who depend on it. The changes, enacted through the One Big Beautiful Bill Act, represent the most significant restructuring of the program in decades.

What Changed — and What It Will Cost

For the first time in the program’s history, states will be required to fund a portion of SNAP benefit payments themselves. Under the new law, states whose payment error rates exceed 6 percent — counting both overpayments and underpayments, not just fraud — must cover between 5 and 15 percent of their total benefit costs. As many as 36 states are expected to face these cost-sharing requirements when they take effect.

The cumulative financial exposure is substantial. States collectively could owe more than $9 billion, according to available projections. Nearly half of the states facing new obligations are expected to owe at least $100 million annually. The largest burdens fall on the most populous states: Michigan faces roughly $300 million per year, Texas could owe an estimated $725 million, and New York may be on the hook for more than $1 billion annually.

The scale of existing improper payments underscores why federal officials pushed for this accountability mechanism. States made a collective $10.1 billion in improper SNAP payments during fiscal year 2025 alone.

The Accountability Argument

Agriculture Secretary Brooke Rollins has defended the cost-sharing structure as a necessary corrective. “These payment error rates are further proof that state accountability is severely lacking in SNAP,” Rollins said.

The federal government’s position is that states have had limited financial incentive to tighten their administration of the program because Washington bore the full cost of errors. Requiring states to share in the financial consequences, proponents argue, will push state agencies to improve their systems and reduce improper disbursements.

The law also tightened eligibility criteria and added new work requirements, changes that have already affected program enrollment. More than 4 million Americans have lost SNAP benefits under the new rules.

States Push Back

State officials are pushing back sharply, particularly against the error-rate penalty structure. New Jersey’s Human Services Commissioner, Stephen Cha, argued that the financial penalties are unlikely to achieve the stated goal. “Penalizing states will do nothing to improve payment accuracy or meaningfully address waste, fraud, or abuse,” Cha said.

New Jersey’s situation illustrates the complexity of the error-rate calculation. The state cut its error rate nearly in half — from 14.33 percent down to 6.86 percent — through sustained administrative effort. Yet even at that improved rate, New Jersey could still owe around $100 million annually under the new threshold.

A survey conducted by the Urban Institute and the American Public Human Services Association found that 39 states responded to questions about their concerns. Nearly a third of participating states flagged eligibility-narrowing policies as a potential risk to their programs, while 11 percent went further and identified the possibility of states withdrawing from SNAP participation altogether as a concern.

Administrative Complexity in Some States

The new cost-sharing structure adds another layer of difficulty for the 10 states — including California, New York, Ohio, and North Carolina — that administer SNAP through county agencies rather than a centralized state office. Coordinating fiscal responsibility across dozens of county governments while meeting the new federal benchmarks could prove especially challenging.

Idaho administers SNAP through the state Department of Health and Welfare. The department has recently been exploring federal rural grant opportunities that could affect how smaller Idaho communities access public services, a sign that state agencies are actively managing federal funding relationships on multiple fronts.

What Comes Next

The fall 2027 deadline gives states roughly a year to prepare financially and administratively. State legislators in many affected states will likely need to consider budget adjustments or program modifications before cost-sharing kicks in.

For states weighing their options, the survey data suggests the choices range from absorbing the new costs to narrowing who qualifies for benefits — each carrying significant political and practical consequences. Whether Congress revisits any provisions before the deadline remains an open question, but no legislative action appears imminent.
