Florida TaxWatch launched a Property Tax Resource Center website to present data on Amendment 3, the November ballot initiative that would raise the homestead exemption to $250,000 by 2028 and requires 60% voter approval.

The amendment proposes to increase the homestead exemption, which TaxWatch estimates would reduce local property tax collections by about $45.8 billion over five years. The organization notes that the change could affect municipal budgets and property tax rates across the state.

The website provides a county‑by‑county map showing projected fiscal impacts and ranks each county by the estimated loss in tax revenue. TaxWatch Chairman David Casey said the center offers independent, data-driven research to help legislators, policymakers, voters and journalists understand the measure’s effects. President and CEO Lt. Gov. Jeff Kottkamp said some voters may be uncertain about what the amendment entails. TaxWatch argues that the current proposal was advanced without adequate review and suggests using the Florida Taxation and Budget Review Commission, which meets every two decades but will convene next year. Republican gubernatorial candidate Byron Donalds said he would ask the commission to consider property tax changes even if the ballot measure fails in November. The microsite follows a court‑ordered revision by Attorney General James Uthmeier that removed promotional language from the official ballot wording. A survey conducted by Sachs Media found that voters responded favorably to the new resource.

The amendment must achieve a 60% majority to pass, and its ultimate impact on homeowner taxes and local government finances remains undetermined.
