Martin County staff warn proposed homestead-exemption amendment could cut $40–50 million in local ad valorem revenue

Martin County staff told the Community Redevelopment Agency on Thursday that a proposed statewide constitutional amendment to expand homestead exemptions would materially reduce local ad valorem revenue and require policy decisions by county leaders.

"It is proposed to happen January 1st, 2027," said Susan Corrales of the Office of Community Development, summarizing the amendment language, which she said would increase homestead exemptions in steps (an initial exemption at $150,000, then $250,000 with later indexing) and also specify what ad valorem revenue counties and municipalities may spend that money on. Corrales said the proposal lists permitted uses such as public safety (law enforcement, fire service, EMS), funding for public schools, road and stormwater infrastructure, natural‑resource projects (including flood control), local bonds and debt service, retirement benefits for local employees, and operations and administration of county offices.

George Stokas, a county staff member who led the fiscal description, told the CRA the county is estimating "about a 40 to 50 million dollar general ad valorem fund reduction" if the measure passes under the scenarios discussed. Stokas said the estimate accounts for the stepped implementation in 2027 and 2028 and does not yet include downstream effects on MSTUs/MSBUs and other dedicated assessments.

Board members and staff discussed the practical options if the referendum passes. Corrales and staff said a “tax shift” could take multiple forms: raising millage on non‑homesteaded property, establishing or increasing fee‑based revenue (beach parking, park fees, library fees), or expanding special taxing units. They also cautioned that some municipalities and programs — especially those that rely on tax increment financing (TIF) tied to CRAs — could face particular stress. "We are an obligation of the county per statute," Corrales said, noting the Board of County Commissioners could choose to modify CRA arrangements.

Stokas gave an example of service‑level exposure: under the initial exemption scenario the county estimates a roughly $9.2 million shortfall in the fire‑rescue MSTU. He said whether that gap would be backfilled from other sources or shown as a service reduction is a policy choice for the Board of County Commissioners. He also emphasized that many capital projects rely on ad valorem dollars as local matches for grants; losing those funds would reduce the county’s ability to leverage 50/50 and other matching grants and could end or delay projects.

Corrales noted a legal challenge over ballot language is being filed; she referenced a complaint reportedly brought by a group identified in the materials as Save Our Voters From Misleading Ballot Language, Inc., and pointed board members to local commentary summarizing the complaint. The referendum remains scheduled for the statewide ballot in November; implementation dates discussed by staff begin in January 2027 and expand in 2028.

Public commenters and board members raised micro‑examples of local effects. Gary Earler, speaking from Port Salerno, asked how local property improvement grants should be protected if recipients later sell properties: "If we're putting out 20 grand ... I want our 20 grand back," he told the board. Other speakers warned that long‑delayed projects could be further postponed if matching funds disappear.

Next steps: staff said they are inventorying projects to determine which fit the amendment’s permitted uses, preparing outreach materials permitted under state law, and will present budget options during the normal 2027 budget process (decisions and prioritization are expected to begin in July 2027). The referendum is on the November ballot; the county will not implement changes until the statutory valuation and budget cycle dates the staff described.
