Duval County's 2025 total millage runs about 17.86 mills. Florida changed how it can set that rate on June 24, 2026, and your August TRIM notice is where you will see it. Enter the four numbers from your notice to find out whether your proposed bill is above or below the rolled-back rate.
Your TRIM (Truth in Millage) notice arrives in August. It is not a bill, it is the preview, and it is where the new state law shows up. It lists last year's taxable value and taxes, this year's proposed taxable value, the rolled-back rate, the proposed millage each Duval County taxing authority wants to adopt, and the date of the public budget hearing where you can speak. The decoder above turns those numbers into a plain answer: is the proposed rate above or below rollback. Duval County's 2025 total millage is about 17.86 mills, of which roughly 6.34 fund schools and about 11.52 cover county, city, and special-district services. On a homesteaded $350,000 home that lands near $5,518 a year today.
The state-level change is the same in every county. On June 24, 2026 the Governor signed SB 4F, which strips the per-capita personal income adjustment from the maximum millage, requires a two-thirds vote to adopt any rate above the rolled-back rate (and a unanimous vote or referendum to exceed 110 percent of it), and forces a budget-cutting exercise before adoption. For the full plain-English explanation, the methodology, and the law sources, see the statewide rollback rate and TRIM decoder.
