The headline number is an estimate with stated conditions. Florida TaxWatch applies a statewide average non-school tax rate of US$10.50 per US$1,000 of taxable value and concludes that homes assessed above US$250,000 would save US$1,035 in 2027 and US$2,085 in 2028, a method set out in its Property Tax Resource Center. Three conditions are built in: the owner is a homesteader, the home is assessed above the full exemption, and the local rate matches the state average. Change any one and the saving changes.
The arithmetic is easy to reproduce. "Roughly US$50,000" is, for the 2026 tax year, exactly US$51,411: a US$25,000 exemption that applies to every levy, plus a second, inflation-indexed portion of US$26,411 that applies to non-school levies only, according to the Florida Department of Revenue's adjustment table. Raising the non-school exemption from US$51,411 to US$150,000 removes US$98,589 of taxable value. At US$10.50 per US$1,000, that is about US$1,035. Raising it to US$250,000 removes US$198,589, or about US$2,085. Our reconstruction matches the published estimate to the dollar.
School taxes sit outside all of this. Florida TaxWatch puts them at approximately 40 per cent of the average bill, and county property appraisers note that only the first US$25,000 of a homestead's assessed value would remain exempt from school levies, as it is today. The larger exemption works on the other 60 per cent.
The table describes the proposal as county appraisers and Florida TaxWatch have summarized it. Every row from 2027 onward is conditional on the vote and on implementing legislation.
