The Centers for Medicare & Medicaid Services has proposed a rule that would tighten how much states can tax hospitals, nursing homes and other health care providers to help pay for Medicaid. CMS estimates the change would cut federal Medicaid spending by roughly $246 billion over the next ten years, mostly by closing financing arrangements the agency says function as disguised refunds to providers. The rule has not been finalized, and the public comment period is still open. For households, the stakes are indirect but real: provider taxes are one of the main ways states raise their share of Medicaid funding, and a smaller pool of state money for the program tends to show up later in eligibility rules, covered benefits or what providers get paid.
How the Indirect Hold Harmless Threshold Works
Medicaid’s provider-tax rules trace back to section 1903(w) of the Social Security Act, which lets states tax hospitals, nursing facilities, managed-care plans and other provider classes to help draw down federal matching dollars, as long as the tax is broad-based, applies uniformly within the class, and doesn’t function as a disguised refund. CMS enforces that last condition with what it calls an indirect hold harmless test: if a state effectively guarantees providers get their tax money back, through Medicaid payments or other state funds, the tax no longer qualifies as legitimate financing. Historically, that test has generally been satisfied as long as the tax stays at or under 6 percent of a provider class’s net patient revenue. The proposed rule, published July 23, 2026, would replace that single flat line with thresholds tied to whether a state’s tax on a given provider class was “enacted and imposed” as of July 4, 2025. A state with no such tax on the books as of that date would face a threshold of zero for that provider class going forward, while a state that already had a tax in place would get a threshold based on what that tax actually raised as a share of net patient revenue on that date.

Why CMS Says the Change Is Worth $246 Billion
The dollar figure comes from CMS’s Office of the Actuary, which projects the new thresholds would reduce federal Medicaid expenditures by about $246 billion from 2026 through 2035, according to the agency’s own fact sheet on the proposal. The estimate is large in part because provider taxes are common: CMS says 49 states and the District of Columbia currently levy at least one health care-related tax, and many of those taxes sit at or near the levels this rule would eventually restrict. The proposed effective dates are staggered. For most provider classes and states, the new thresholds would take effect October 1, 2026, the start of the next state fiscal year for much of the country. States that expanded Medicaid to the broader adult population would get an extra year on most permissible classes, with those particular thresholds not taking effect until October 1, 2027. Both dates depend on the rule actually being finalized in something close to its current form, which has not happened.
Why States Lean on Provider Taxes to Fund Medicaid
Medicaid is a federal-state partnership: Washington matches a share of what a state spends, but the state has to come up with its own share first. Provider taxes have become one of the most common tools for doing that, because the tax revenue can be counted toward a state’s own share, letting the state draw down more federal matching money without raising general tax revenue elsewhere. When federal rules narrow what counts as a legitimate provider tax, states lose some of that financing tool and generally respond in one of a few ways: trimming who qualifies for coverage, narrowing which services or providers get paid what, or finding other state revenue to fill the gap. None of that happens automatically under this proposal, which is a rule about how CMS evaluates a financing mechanism, not a rule that itself changes anyone’s Medicaid eligibility or benefits today. But because the mechanism funds a meaningful share of many state Medicaid budgets, a shift this size tends to work its way into state budget decisions over time.
New Rules for Insurer Taxes and State Reporting
Beyond the threshold change, the proposed rule would also formally establish “services of health insurers” as its own permissible tax class, which would bring existing state taxes on health insurers under the same federal oversight and limits that already apply to taxes on hospitals or nursing homes. It also proposes new reporting requirements, requiring states to submit detailed data on their health care-related taxes so CMS can calculate the new thresholds and monitor compliance going forward. A separate piece of the same rule would eliminate an alternative test, sometimes called the 75/75 test, that has let some taxes above the 6 percent line remain permissible under certain conditions. That specific change, and what it could mean for hospital financing in particular, is significant enough on its own to warrant a closer look at the underlying math.
What Happens Next, and the September 21 Deadline
Because this is a proposed rule and not a final one, none of the new thresholds are actually in effect yet. CMS opened a formal comment period when it published the rule, and members of the public, state Medicaid agencies, hospital associations and other stakeholders can submit comments through the Federal Register docket. Those comments are due by September 21, 2026. After that date, CMS is expected to review the input and decide whether to finalize the rule as proposed, revise it, or take some other action, though the agency has not committed to a timeline for issuing a final rule. CMS had previewed some of its thinking on the “enacted” and “imposed” definitions earlier, in a November 2025 guidance letter to state Medicaid directors, before revising that interpretation in this newer proposal, a reminder that the details here have already shifted once and could shift again before anything is final.
