Collier County property taxes
Collier County — Naples, Marco Island and the western Everglades — pairs one of Florida's LOWEST average total millages with some of its highest home values, which is why bills here can still run large at a low rate. It is also a BUYER-pays county for the owner's title policy by local custom. County record searches run through the county's own portal — the lookup tool links you straight to the official pages.
The 2025 numbers
Collier County's average total millage on the 2025 certified roll is 9.8185 mills — about $9.82 for every $1,000 of taxable value — the 65th-highest countywide average of Florida's 67 counties. It splits like this:
| Levy group | Mills | What it funds |
|---|---|---|
| School district | 4.249 | School board operating and debt levies — the portion the additional homestead exemption does not reduce |
| Non-school | 5.5695 | County commission, municipal, water management, independent and special districts |
| Average total | 9.8185 | Taxable-value-weighted countywide average, Florida DOR "Millage and Taxes Levied Report," 2025 roll |
This is a countywide average — a planning number, not your bill. Actual millage depends on the taxing districts covering the parcel (city, MSTU, special districts), and real bills add non-ad-valorem assessments (fire, solid waste, CDD) that no millage math captures.
What that means in dollars
Engine-computed examples at Collier County's average millage, using the school/non-school split above:
| Scenario | Estimated annual tax |
|---|---|
| $300,000 assessed value, homestead (both exemptions) | ≈ $2,552.99 |
| $500,000 assessed value, homestead (both exemptions) | ≈ $4,516.69 |
| $300,000 assessed value, no homestead (investment or second home) | ≈ $2,945.55 |
The homestead rows apply the first $25,000 exemption (§196.031(1)(a), all levies) and the additional exemption up to $26,411 (§196.031(1)(b), non-school levies only, 2026 CPI-indexed) — nothing else. Widow/widower, disability, veteran, senior and other programs stack on top: the buyer estimator models all eleven.
Buying in Collier County? The listing's bill is not your bill
Florida assessed values reset to market at sale (§193.155) — the seller's Save Our Homes cap dies at closing, and your first full bill is computed from what you paid, not what they paid. Non-homestead property carries its own 10 percent assessment cap (§193.1554), which also does not transfer. Run the buyer estimator with Collier County pre-selected, and if you're moving a Florida homestead, the portability calculator computes what you can carry with you.
At closing, local custom in Collier County puts the owner's title-insurance premium on the buyer's side (custom, not law — the contract controls). The title calculator and seller net sheet both carry the county custom.
