PropertyTaxImpact.com now live for all Florida counties

PropertyTaxImpact.com, a free public tool launched by Fort Lauderdale resilience firm Brizaga, provides homeowners and local governments with a detailed breakdown of the proposed Amendment 3's impact on property taxes. The site, now live for all 67 Florida counties, calculates the amendment's effect on individual property tax bills and city and county budgets, using public tax rolls and adopted budgets as its data source.

The proposed Amendment 3, which would raise the homestead exemption on non-school property taxes to the first $250,000 of assessed value by 2028, has been a topic of debate in Florida. Supporters argue it would be a tax cut, while opponents contend it would create a budget hole. Neither perspective fully explains the impact on homeowners or local governments.

Brizaga, a civil and coastal engineering and adaptation consulting firm, has developed PropertyTaxImpact.com to address this gap. The tool allows residents to look up the amendment's effect on their own property and the cities and counties that serve them. Every figure on the site is derived from public property records and adopted budgets, not statewide estimates. This transparency aims to provide a clearer picture of the amendment's financial implications.

Amendment 3 will be on Florida's ballot on November 3, 2026. It would raise the homestead exemption on non-school property taxes to the first $250,000 of assessed value by 2028. This change would lower tax bills for homesteaded properties and reduce the amount of property taxes collected by cities and counties.

Brizaga's free tool, PropertyTaxImpact.com, shows how Amendment 3 would affect individual homeowners' property tax bills and the city and county budgets those taxes support. The site now covers all 67 Florida counties. Residents can enter their address to see the amendment's effect on their property and the local governments that serve them. The tool pulls the parcel's assessed value directly from the county property appraiser's roll, ensuring no estimates or typing are required.

The tool presents the loss in a clear, standardized format for each jurisdiction. It includes the estimated dollar impact for 2027 and 2028, the share of that government's General Fund the loss represents, and a line-by-line breakdown of the General Fund, with the largest items listed first. Some pages carry a Verified mark, indicating that the government's finance office has confirmed the figures against what it reported to the state.

The effect of Amendment 3 is uneven across Florida's 67 counties. How much a government loses depends on how much of its tax base is homesteaded and how heavily its budget relies on property tax. Brizaga's first release covered 158 city and county governments in seven counties. Their first-year (2027) figures include:

- Broward County: The county government would lose an estimated $192.6 million in 2027 and $333.5 million in 2028. Its 32 city and county governments together would lose $401.9 million in the first year. Five Broward cities (Tamarac, Lauderdale Lakes, West Park, Margate, and North Lauderdale) could not recover the loss even by raising their millage to the state's 10-mill ceiling. - Miami-Dade County: 35 local governments would lose $277.3 million in the first year. - Palm Beach County: 40 local governments would lose $221.8 million in the first year. The county government would lose $384.3 million across 2027 and 2028 combined. The Village of Westlake would lose 58.4% of its General Fund, the steepest share of the 158 governments in the first seven counties. - Hillsborough and Pinellas counties: 29 local governments would lose $348.7 million in the first year. - Orange and Seminole counties: 22 local governments would lose $203.1 million in the first year. Seminole County's government would lose 22.3% of its General Fund, the steepest share of the seven county governments first analyzed.

The figures on PropertyTaxImpact.com trace back to public sources, including each county's 2026 preliminary tax roll, adopted millage rates, and local governments' audited financial statements and budget filings reported to the state. Brizaga calculates the tax change for every homesteaded parcel individually and rolls those changes up to the city and county level. It then measures each total against the General Fund that property taxes support.

Before running the model on this year's numbers, Brizaga calibrated it against certified tax rolls. It reproduced certified countywide totals to within 0.4% and every individual city to within 2%. Where local officials have published their own estimates, Brizaga's independently built figures land close to them.

Brizaga's work centers on resilience: how a community handles shocks and stressors, and whether it keeps functioning and recovers. That work usually involves storms, flooding, and extreme heat. But a community's finances face shocks too, and Brizaga's team saw Amendment 3 as a clear example of one. No individual city or county chose it, yet each would have to absorb it. How hard it hits depends on how much of each government's budget rests on the tax it would reduce.
