The One Big Beautiful Bill Act freezes every state’s Medicaid provider taxes at the rates in place on July 4, 2025, and for states that expanded Medicaid under the Affordable Care Act it phases the maximum allowable tax rate down from 6 percent to 3.5 percent between fiscal years 2028 and 2032. The law also tightens the rules that let states impose non-uniform taxes by waiver, and federal analysts project the combined changes will cut federal Medicaid spending by roughly $226 billion over ten years.1Library of Congress.

The Freeze That Took Effect in July 2025
As of July 4, 2025, no state can create a new provider tax or raise the rate of an existing one. The moratorium covers all 19 classes of healthcare providers that federal law allows states to tax, from hospitals and nursing facilities to managed care organizations, physician services, ambulance services, and prescription drugs.2Library of Congress. Medicaid Provider Taxes
If your state was taxing hospitals at 5 percent on the date the law was enacted, it cannot move that rate to 5.5 percent, even though 5.5 would still sit below the old 6 percent safe harbor. If your state taxed hospitals and nursing homes but never imposed a managed care organization tax, it cannot add one now. Starting October 1, 2026, the door closes further: no newly enacted provider tax will qualify for the federal safe harbor at all.1Library of Congress. Health Coverage Provisions in One Big Beautiful Bill Act (H.R. 1)
The Congressional Budget Office estimated the freeze alone would reduce federal Medicaid spending by about $87 billion over ten years, the single largest savings item among the law’s provider tax changes. States that had already built out their tax structures before July 2025 are locked in at a higher base than states that still had room to grow.
The Safe Harbor Drop for Medicaid Expansion States
For states that expanded Medicaid under the ACA, the law goes past a freeze and actively cuts the safe harbor threshold. Beginning in fiscal year 2028, the maximum provider tax rate that avoids a federal penalty falls by half a percentage point each year:
- FY 2028: 5.5 percent
- FY 2029: 5.0 percent
- FY 2030: 4.5 percent
- FY 2031: 4.0 percent
- FY 2032 and after: 3.5 percent
The reduction reaches most provider classes, including hospitals, managed care organizations, physician services, and ambulance services. Two categories keep the old 6 percent ceiling regardless of expansion status: nursing facilities and intermediate care facilities for individuals with intellectual disabilities.1Library of Congress. Health Coverage Provisions in One Big Beautiful Bill Act (H.R. 1)
Non-expansion states are not subject to the phase-down. Their taxes stay frozen at current levels, and the 6 percent ceiling remains in place. The split treatment is deliberate and ties a financial consequence to the expansion decision itself.
The reach is broad. According to the most recent federal data, 45 states and the District of Columbia had at least one provider tax above 3.5 percent of net patient revenue, and 32 states had at least one tax above 5.5 percent.3Medicaid and CHIP Payment and Access Commission. Health Care-Related Taxes in Medicaid At least 25 expansion states have one or more provider taxes above the eventual 3.5 percent floor and will need to restructure how they finance their share of Medicaid.
Tighter Rules for Non-Uniform Tax Waivers
Federal law has long required provider taxes to be broad-based and uniform, meaning they apply to every provider in a given class at the same rate. States that wanted to charge different rates within a class could apply to the Department of Health and Human Services for a waiver, which was granted if the tax was “generally redistributive.”4Social Security Administration. Social Security Act 1903
The Big Beautiful Bill narrows that pathway. Under the new rules, a tax is automatically disqualified from being considered generally redistributive if either of the following is true:
- The tax rate on a provider’s Medicaid revenue, bed days, or member months is higher than the rate applied to its non-Medicaid equivalents.
- Providers with a smaller share of Medicaid patients pay a lower tax rate than providers with a larger share.
States also cannot use indirect proxies for Medicaid volume, such as tax tiers keyed to geography or facility size, to get the same result.5Federal Register. Preserving Medicaid Funding for Vulnerable Populations – Closing a Health Care-Related Tax Loophole Several states had built multi-tier structures that passed the older statistical test while charging higher effective rates to Medicaid-heavy providers, and CMS characterized those designs as a loophole. Under the final rule, CMS also changed its posture from “automatically” approving qualifying waivers to treating them as “approvable,” which gives the agency more room to review individual state designs.
Hold Harmless Enforcement Bites Harder
Federal law bars states from guaranteeing that taxed providers get their money back. The prohibited arrangements take three forms: direct payments to taxpaying providers correlated to what they paid in tax, guarantees that Medicaid reimbursement will offset the tax, and, when the tax exceeds the safe harbor threshold, a presumption that providers are being indirectly held harmless.4Social Security Administration. Social Security Act 1903
CMS guidance treats both formal contracts and informal understandings among providers to redistribute Medicaid payments after receipt as covered by the prohibition.6Medicaid.gov. Health Care-Related Taxes and Hold Harmless Arrangements Involving the Redistribution of Medicaid Payments If CMS finds a hold harmless arrangement, it reduces the state’s claimable Medicaid expenditures before calculating the federal match, so the state loses federal dollars on top of the revenue it already spent.5Federal Register. Preserving Medicaid Funding for Vulnerable Populations – Closing a Health Care-Related Tax Loophole
As the safe harbor threshold drops for expansion states, the margin between a compliant tax and one that trips the hold harmless test shrinks. A state that was safely below 6 percent may soon be near or over 3.5 percent, and the same enforcement rule will apply at the lower ceiling.
Compliance Deadlines States Are Working Against
The final rule implementing the provider tax provisions took effect on April 3, 2026. Different taxes face different deadlines to come into compliance with the uniformity and waiver rules:
- Managed care organization taxes with a waiver approved within two years before April 3, 2026 must comply by January 1, 2027.5Federal Register. Preserving Medicaid Funding for Vulnerable Populations – Closing a Health Care-Related Tax Loophole
- Managed care organization taxes with a waiver approved more than two years before April 3, 2026 must comply by the first day of the state’s fiscal year 2028 (July 1, 2027 for a state on a July-through-June fiscal year).
- All other provider taxes must comply by the first day of the state’s fiscal year 2029, but no later than September 30, 2028.
The Secretary of Health and Human Services may grant a transition period of up to three fiscal years for states whose existing waiver taxes are newly disqualified under the tighter generally-redistributive standard.1Library of Congress. Health Coverage Provisions in One Big Beautiful Bill Act (H.R. 1) The discretion is not guaranteed, and states should not assume they will receive the full three years.
The safe harbor phase-down for expansion states runs on its own clock, starting in fiscal year 2028 and stepping down annually through fiscal year 2032, which gives states somewhat more runway on rate reductions than on waiver compliance.
What This Means for State Budgets and Coverage
The combined restrictions are projected to reduce federal Medicaid investment by nearly $226 billion over ten years. States are already weighing how to absorb the loss. Options on the table include cutting reimbursement rates paid to hospitals and doctors who treat Medicaid patients, trimming eligibility for certain populations, and eliminating coverage for optional services such as dental or behavioral health care.
An estimated 2.4 million people could lose Medicaid coverage over the next decade as a result. The impact falls harder on expansion states, which face both the freeze and the shrinking safe harbor. Non-expansion states avoid the phase-down but still cannot grow their provider tax revenue to keep pace with rising healthcare costs.
The nursing home carve-out gives some states a partial cushion. Because nursing facilities and intermediate care facilities for individuals with intellectual disabilities keep the 6 percent safe harbor, states that lean on nursing home taxes for long-term care financing retain more flexibility there. Hospital taxes, managed care organization assessments, and most other provider class taxes face the full weight of the new limits, and the alternatives for replacing lost revenue, whether raising general taxes, cutting other budget priorities, or reducing Medicaid benefits, are all politically and legally difficult.
