A major federal overhaul of food assistance is shifting more Supplemental Nutrition Assistance Program costs from Washington to state budgets. In Tennessee, that change could leave state government responsible for tens of millions of dollars in new spending, with outside estimates putting the total annual exposure as high as $243 million. The change stems from the One Big Beautiful Bill Act of 2025 and the federal rules now being implemented around it.
Tennessee’s potential SNAP bill now includes two separate cost shifts
The new federal framework changes both how SNAP administrative costs are shared and when states may have to help pay for benefits that were historically covered entirely by the federal government. According to the U.S. Department of Agriculture’s Food and Nutrition Administration, the federal share of annual SNAP administrative costs drops from 50 percent to 25 percent beginning in fiscal year 2027, which starts October 1, 2026. That means Tennessee, like other states, would be responsible for 75 percent of approved administrative costs instead of half.
The Sycamore Institute, a nonpartisan Tennessee policy research center, reported that Tennessee’s SNAP administrative costs totaled about $256 million in federal fiscal year 2023. Based on that shift alone, the institute said the Tennessee Department of Human Services estimates it would need an additional $77 million in recurring state funds to cover the higher state share. NewsChannel 5 in Nashville also reported this month that the Tennessee Fiscal Review Committee put the added administrative cost at roughly $77 million annually.
A second cost shift begins in federal fiscal year 2028, or October 1, 2027, and depends on a state’s SNAP payment error rate. Sycamore reported that, using Tennessee’s federal fiscal year 2024 SNAP benefit spending, the state could owe between $81 million and $243 million toward benefit costs if its error rate remains above 6 percent. That is the figure behind the higher-end warning now circulating in Tennessee policy discussions.
For Tennessee, the practical impact is budgetary, not a confirmed immediate reduction in monthly benefits. Robin Yeh of The Sycamore Institute told Tennessee Lookout in a June 29, 2026, report that the new rules do not necessarily change the amount of benefits people receive, but they could affect how the state administers the program and verifies eligibility. Tennessee Lookout reported that states with payment error rates between 8 percent and 10 percent could be required to cover 10 percent of benefit costs under the law.
Federal data show Tennessee has recently posted error rates above the new 6 percent threshold. USDA’s fiscal year 2024 SNAP payment error data listed Tennessee at 9.47 percent, and a later USDA release on fiscal year 2025 error rates showed Tennessee at 9.44 percent. Under the law described by the Associated Press, states can use either their 2025 or 2026 error rates to determine what share of SNAP benefit costs they must pay starting in October 2027.
What is not yet known is the exact amount Tennessee will ultimately owe once the cost-sharing rules take effect. The final bill will depend on future benefit totals and which payment error rate applies under federal law. State officials also have not publicly released a final statewide spending plan showing how Tennessee would absorb the maximum estimated exposure.
The cost shift is rooted in federal legislation enacted in 2025 and the rulemaking that followed. USDA said the administrative funding change was made in response to Section 10106 of Public Law 119-21, the One Big Beautiful Bill Act of 2025. The Associated Press reported the broader work and cost-share provisions were designed to increase state accountability and generate federal savings.
The key measurement driving the benefit-cost penalty is the SNAP payment error rate, which does not necessarily mean fraud. USDA says the rate measures how accurately states determine eligibility and benefit amounts, including overpayments and underpayments found through quality control reviews. Tennessee’s own Department of Human Services explains on its SNAP quality review page that cases are checked under federal quality control rules and may require interviews and documentation review.
For Tennessee households using SNAP, the immediate takeaway is that benefits continue while state officials prepare for higher program costs and closer scrutiny of eligibility decisions. Analysts and advocates have said the state’s response could focus on reducing payment errors before October 1, 2027, when benefit cost-sharing begins. As of now, the most concrete near-term date is October 1, 2026, when the higher 75 percent state share for SNAP administrative costs is scheduled to start.
