Duval County Medicaid Bill Hits $22.7M as Property Tax Cut Looms

Jacksonville and Duval County will contribute $22,663,520 to Florida's Medicaid program during the current fiscal year, according to new state projections released this week by Florida's top economists. The figure makes Duval the fifth-largest county contributor statewide, behind Miami-Dade, Broward, Hillsborough, and Orange counties.

The Medicaid obligation comes as local governments across Florida brace for a potentially dramatic squeeze on property tax revenue. If voters approve Amendment 3 in November, cities and counties would see nearly $5 billion in revenue cuts in the first year alone — meaning services that include healthcare, public safety, parks, and infrastructure would compete for a shrinking pool of tax dollars.

What's happening

State economists meeting this week finalized projections showing Florida's 67 counties will collectively pay nearly $420 million toward Medicaid in the current fiscal year. The total is expected to climb to approximately $452 million a year from now, when Amendment 3 would take effect if passed by voters. County-specific projections for next year are not yet available.

Florida law requires counties to contribute to the state's share of Medicaid costs. How much each county pays depends on a formula based on the number of Medicaid enrollees in that county as a percentage of the state's total Medicaid population. Twenty-nine "fiscally constrained counties" receive state offsets to reduce their burden, with offset amounts calculated by the Florida Department of Revenue.

As of June 30, 2026, Florida had nearly 3.9 million residents enrolled in Medicaid, the joint federal-state health insurance program for low-income individuals, the elderly, and people with disabilities. Unlike Medicare, which is entirely federally funded, Medicaid requires states — and in Florida's case, counties — to share the cost.

Amendment 3, which goes before voters in November, would dramatically expand the homestead exemption for existing Florida residents. The exemption for non-school ad valorem taxes would increase from the current $50,000 to $250,000 by 2028, with the Legislature authorized to raise it further thereafter. The Florida Association of Counties opposes the amendment.

Impact on Jacksonville and Duval County services

Duval County's nearly $23 million Medicaid payment represents a mandated expense the local government cannot reduce, even as overall revenue may shrink. If Amendment 3 passes, the county would face the challenge of meeting this fixed healthcare obligation while absorbing a share of the statewide $5 billion revenue reduction in year one.

The collision of rising mandatory costs and falling revenue would force difficult choices about county services. Police and fire protection, road maintenance, parks and recreation, library operations, and environmental programs would all draw from the same diminished tax base. Services that are discretionary or lack dedicated funding streams could face deeper cuts as fixed obligations like the Medicaid contribution consume a larger share of available dollars.

Jacksonville's consolidated city-county government structure means the revenue squeeze and competing priorities would play out in City Council budget deliberations. With both municipal services and traditional county functions funded from the same property tax base, the council would need to balance neighborhood-level concerns — such as fire station staffing and park hours — against countywide mandates like the Medicaid payment.

What it means for public hospitals and healthcare access

County tax dollars help sustain Florida's large public hospital systems, including UF Health Jacksonville, which serves as the region's safety net hospital and trauma center. These facilities use local funding to maintain positive operating margins while providing critical services that don't generate revenue, such as emergency care for uninsured patients and specialized trauma services.

Justin Senior, chief executive officer of Safety Net Hospital of Florida, told Florida Public Radio that reduced county revenue could force health systems to make difficult decisions about which services to continue offering. Emergency departments, burn units, neonatal intensive care, and other high-cost, low-margin services depend on the financial cushion that public support provides.

For Northeast Florida residents, the potential impact extends beyond UF Health Jacksonville. The regional healthcare network includes county-supported community health centers, mental health crisis services, and programs addressing substance abuse and homelessness — services that often operate on thin margins and serve populations with limited ability to pay. A revenue crunch at the county level would likely mean reduced capacity in exactly the programs that serve the Medicaid population the county is required to help fund.

The arithmetic creates a particularly tight bind: Duval County must pay its share to support statewide Medicaid enrollment while simultaneously facing pressure on the local tax revenue that helps hospitals and clinics serve those same Medicaid patients and uninsured residents.

Property tax politics and local control

Amendment 3 represents the latest chapter in Florida's ongoing tension over property taxes and local government funding. Supporters of the amendment argue that rising property values — driven by in-migration and a hot real estate market in recent years — have increased homeowners' tax bills even when millage rates stay flat, and that a larger exemption would provide relief to long-term residents.

Opponents, including the Florida Association of Counties, counter that the amendment would severely constrain local governments' ability to respond to growth-driven demands for infrastructure and services. In fast-growing areas like Northeast Florida, new roads, expanded water and sewer systems, additional school capacity, and more fire stations represent real costs that property taxes have traditionally funded.

The proposed exemption applies only to non-school ad valorem taxes, meaning school district revenue would not be directly affected. However, cities and counties fund services that indirectly support quality of life and economic development — the factors that drive the school performance and livability metrics attracting new residents in the first place. Reducing those services could undermine the growth engine even as growth continues to demand new infrastructure.

For Jacksonville and Duval County, the political dimension is particularly complex. The consolidated government serves both urban core neighborhoods with aging infrastructure and sprawling suburban growth areas demanding new capacity. Amendment 3 would reduce the revenue available for both, forcing elected officials to choose between maintenance and expansion,core services and quality-of-life amenities.

What happens next

Voters will decide Amendment 3's fate in the November 2026 general election. If it passes, the homestead exemption increase would phase in, reaching the full $250,000 by 2028. The nearly $5 billion first-year revenue reduction to cities and counties would begin when the amendment takes effect.

Duval County's Medicaid obligation for the next fiscal year — projected at part of the statewide increase to $452 million — will become clearer when county-specific numbers are released. The county and City Council will incorporate both the Medicaid payment and any Amendment 3 impact into budget planning for the fiscal year beginning October 1, 2027.

If the amendment fails, county governments would retain current revenue structures but still face the rising Medicaid costs built into state projections. Either way, local officials will be navigating the challenge of funding mandated state contributions while meeting voters' expectations for police, fire, roads, and parks.

As Northeast Florida continues to absorb thousands of new residents each year — drawn by affordability, job growth, and quality of life — the debate over Amendment 3 frames a fundamental question about how growth is financed. The region's ability to build the infrastructure and services that make it attractive depends on local revenue that the amendment would significantly reduce, even as state-mandated costs like the Medicaid contribution continue to rise.
