Florida’s November property-tax fight gained a major financial backer this week as Florida Realtors poured $10 million into Vote Yes on 3, the political committee supporting Amendment 3.

The contribution gives supporters their first major campaign war chest less than two months before Election Day. Florida Realtors, which has more than 230,000 members, formally endorsed the measure last month and argues that reducing the continuing property-tax burden can make homeownership more attainable.

What Amendment 3 Would Do

Under implementing legislation approved by lawmakers, qualifying Floridians who maintained permanent residence as of December 31, 2026, would receive a homestead exemption from non-school property taxes of up to $150,000 beginning January 1, 2027. That amount would rise to as much as $250,000 beginning January 1, 2028, with positive inflation adjustments beginning in 2029.

The school-district portion of a homeowner’s property-tax bill would not receive the expanded exemption.

The proposal also changes taxation of non-homestead property. The amendment would limit annual increases in assessed value for those properties to 5 percent, down from the current constitutional 10 percent cap.

For people establishing Florida residency on or after January 1, 2027, the implementing legislation creates a different phase-in. Those homeowners would initially receive up to a $50,000 exemption from non-school levies, adjusted for inflation, and could become eligible for the larger exemption after maintaining Florida residency for five years.

Why The Fight Is Intensifying

Supporters say Florida homeowners need substantial property-tax relief after years of rising housing costs and property values. The $10 million Florida Realtors contribution gives the campaign significant resources to make that case to voters statewide.

Opposition has come from organizations representing local-government and public-safety interests. Sheriffs, police and firefighter organizations have warned that reducing property-tax collections could put pressure on the local revenue used for law enforcement, fire protection, emergency medical services and other services.

The amendment also has faced a legal fight over the wording voters will see. A judge ruled in August that portions of the original ballot language were not sufficiently neutral and ordered the state to rewrite it. The ruling did not remove Amendment 3 from the ballot.

What It Could Mean In Indian River County

For Indian River County homeowners, the practical effect would depend on a property’s assessed value, homestead status, applicable taxing authorities and future millage rates.

That distinction matters. A home’s market value is not necessarily its taxable value, and the expanded exemption would apply to non-school levies rather than the entire tax bill. Because future millage rates and individual assessments vary, a simple home-price calculation cannot accurately predict every homeowner’s savings.

What is clear is that a homeowner with sufficient taxable homestead value could have substantially more of that value removed from county, municipal and other non-school property-tax calculations once the amendment is fully phased in.

The other side of the equation will be closely watched by Indian River County, Vero Beach, Sebastian, Fellsmere and other local taxing authorities. A larger exemption means less taxable value available to those governments unless growth, millage changes or other revenue offsets make up the difference.

That sets up the central argument Florida voters will decide in November: whether substantially lowering the property-tax burden on qualifying homeowners outweighs concerns about the effect on local-government revenue.

Amendment 3 requires approval from at least 60 percent of Florida voters to become part of the state Constitution.
