Reading your Miami-Dade County TRIM notice.

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 Miami-Dade 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. Miami-Dade County's 2025 total millage is about 17.59 mills, of which roughly 6.63 fund schools and about 10.96 cover county, city, and special-district services. On a homesteaded $350,000 home that lands near $5,444 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.

Miami-Dade County: common questions.

What is the rollback rate in Miami-Dade County?
The rolled-back rate is the millage that would raise the same total revenue this year as last year on this year's taxable values, excluding new construction. Miami-Dade County's 2025 total millage is about 17.59 mills, but its 2026 rolled-back rate is set during this summer's budget process and printed on your August TRIM notice. Compare the proposed millage on that notice to the rolled-back rate: above it means more revenue from existing property, at or below means not.
Did property taxes go down in Miami-Dade County in 2026?
It depends on your jurisdiction's vote and your own taxable value. SB 4F, signed June 24, 2026, lowers the maximum rate Miami-Dade County and its cities can adopt without a supermajority and requires a budget-cutting exercise first, which pushes toward lower rates. But each authority sets its own millage at its August and September hearings, and a rising assessed value can still raise your bill. Enter your TRIM numbers above to see your real result.
How much is property tax on a $350,000 home in Miami-Dade County?
On a homesteaded $350,000 home with the standard $50,000 exemption, Miami-Dade County's 2025 total millage of about 17.59 mills works out to roughly $5,444 a year. Your exact bill varies by city, CDD, and special district. See the full breakdown on the Miami-Dade County property tax page.
