Every SNAP benefit ceiling now on the books traces back to a single grocery list USDA priced out in 2021, and a provision buried in last year’s tax-and-spending law keeps that list locked in place until at least October 2027. The rule does not touch the income and deduction math that decides who qualifies for food assistance. It freezes the ingredient list and price tag behind the maximum monthly allotment itself — the Thrifty Food Plan, the model diet USDA uses to calculate how much a household of a given size can receive. For anyone counting on that benefit, the ceiling is now set by 2021 grocery prices carried forward with inflation, not by a fresh look at what a cart of groceries costs today.
How a 2021 Grocery List Became Today’s Benefit Ceiling
The Thrifty Food Plan is USDA’s model for a minimally adequate, budget-conscious diet, and it has doubled as the basis for the maximum SNAP allotment since the program’s modern benefit formula took shape. The plan’s last full makeover came in August 2021, when USDA concluded that a nutritious, practical diet cost 21% more than the existing plan assumed and raised the average per-person benefit by $36.24 a month — the first time in 45 years the agency let the plan’s cost rise faster than inflation, according to USDA’s own announcement of the change.
Every fiscal year’s maximum allotment since October 2021 has descended from that repricing, nudged annually for inflation but never rebuilt from scratch. That single decision has been the fault line in SNAP funding debates ever since, because a benefit tied to a revalued market basket moves differently than one tied purely to a price index.

What Section 10101 Actually Freezes
Section 10101 of Public Law 119-21, the tax-and-spending act President Trump signed on July 4, 2025, rewrites how often and how far that market basket can move. According to USDA’s Food and Nutrition Service implementation memo issued to state SNAP agencies on September 4, 2025, the provision amends Section 3(u) of the Food and Nutrition Act to limit future re-evaluations from increasing the cost of the Thrifty Food Plan, and it sets October 1, 2025 as the effective date for that limit. The memo states plainly that the market baskets “may be reevaluated no earlier than October 1, 2027.”
That is a floor, not a promise of action in 2027 — USDA is barred from repricing the plan sooner, but nothing compels a repricing the moment the window opens. And when a re-evaluation does eventually happen, the same provision caps what it can do: it can no longer function as a vehicle for raising the plan’s cost the way the 2021 review did. The law also writes the household-size adjustments used to scale the maximum allotment directly into statute, taking that formula out of USDA’s regulatory discretion.
The October Adjustment That Doesn’t Stop
Freezing full re-evaluations is not the same as freezing the dollar figure. The same section of the memo requires an annual adjustment each October to reflect the change in the Consumer Price Index for All Urban Consumers, published by the Bureau of Labor Statistics, over the most recent 12-month period ending in June. That CPI-U pass-through is the mechanism carrying maximum allotments forward year to year while the underlying market basket stays fixed. FNS’s current OBBB provisions page, last updated June 11, 2026, still lists Section 10101 as an active implementation item and links out to the agency’s fiscal year 2026 cost-of-living adjustment memorandum — confirmation that the annual inflation update, not a new market-basket review, is what has been moving benefit ceilings since the freeze took hold.
Why the 2021 Repricing Became the Fight
The gap between an inflation adjustment and a full re-evaluation is exactly what made the 2021 change contentious in the first place. A 2018 farm bill directed USDA to reassess the plan by 2022, but earlier law had required any update to stay cost-neutral. USDA’s 2021 review dropped that constraint and concluded the diet cost more than the CPI alone would have shown, which is why the benefit increase that October ran well ahead of ordinary inflation adjustments. Section 10101 responds directly to that precedent: it keeps the CPI-U mechanism running every year but takes the cost-neutral guardrail the 2018 farm bill removed and writes a version of it back into law through 2027 and beyond.
What the Statute Locks In for Households
For a household applying for or renewing SNAP benefits between now and October 2027, the practical effect is a benefit schedule that moves with the government’s own measured inflation but not with any broader reassessment of food prices, food composition data or consumption patterns — the same inputs USDA used to justify the 2021 increase. The statute’s household-size adjustment tables, now fixed in law rather than agency regulation, apply on top of that inflation-only baseline. Barring new legislation, the next point at which USDA could revisit the market basket itself — and only within the cost limits Section 10101 imposes — is the date FNS’s own implementation memo fixes in writing: October 1, 2027.
Keeping a SNAP Case Current While the Formula Stays Fixed
None of the math above changes the paperwork a household still has to file to keep receiving the benefit that formula produces. Recertification periods, reporting deadlines and the documents a caseworker asks for do not pause because the market basket behind the allotment is frozen through 2027. The deadline that determines whether a case stays open rarely gets printed next to the rule that sets the benefit amount, which is where a renewal record instead of a rule summary becomes the practical next step.
