Collier County Property Tax Calculator
Estimate your Collier County property tax in seconds — plus the current millage rate, how your bill is calculated, the exemptions that cut it, and the deadlines that matter.
Collier County sits in Southwest Florida — Naples, Marco Island, and the surrounding communities. Like the rest of Florida, there is no state property tax; your bill is set entirely by local taxing authorities. Collier County’s combined rate is on the lower end for Florida, so understanding it before you buy matters.
How this calculator works
This calculator uses Collier County’s approximate combined rate of 11.2 mills and the same method the property appraiser uses: your home value, minus the $50,000 homestead exemption if it’s your primary residence, divided by 1,000 and multiplied by the millage. That mirrors a new buyer’s first-year bill, because Florida reassesses a home to its purchase price the January after it sells. Long-time owners often pay less, since the Save Our Homes 3% cap holds their assessed value below market. Uncheck the homestead box for a second home, rental, or investment property. Your exact bill still depends on your city, school-district levies, and any special or community-development districts.

How Much Is Property Tax in Collier County?
Collier County’s median home value is roughly $610,000 (2026 estimate). Long-time homesteaded owners protected by Florida’s Save Our Homes 3% cap often pay an effective rate near 1% of market value, because their assessed value sits below today’s market price.
A brand-new purchase is different. The home is reassessed to its sale price, so a new buyer’s first-year bill runs closer to the full 11.2-mill rate. Estimated first-year tax on a homesteaded home in Collier County:
| Home Value | Taxable (after homestead) | Est. Annual Tax | Est. Monthly |
|---|---|---|---|
| $300,000 | $250,000 | $2,800 | $233 |
| $400,000 | $350,000 | $3,920 | $327 |
| $500,000 | $450,000 | $5,040 | $420 |
*Assumes the home is your homesteaded primary residence ($50,000 exemption) and reassessed to the purchase price. Estimates only — confirm with the Collier County Property Appraiser.
Amendment 3 could change this bill. It would raise the homestead exemption on non-school taxes to $150,000 in 2027 and $250,000 in 2028. Of Collier County’s 9.8185 total mills, 5.5695 are non-school — so a homesteaded home assessed at $250,000 or more would save about $557 a year in 2027 and $1,114 from 2028. You must be a Florida resident by December 31, 2026 to qualify as it phases in. Run the Amendment 3 property tax calculator →

The Collier County Property Tax Rate (Millage)
Property tax rates are expressed in mills — 1 mill equals $1 of tax per $1,000 of taxable value. Collier County’s approximate average combined millage is about 11.2 mills, versus a statewide county average near 16 mills. The combined rate stacks the county, your city or municipality (Naples and Marco Island set their own), the school board, the water management district, and any special assessment or community-development districts (CDDs) that cover your parcel — which is why two homes of the same price can carry different bills.
At 11.2 mills, Collier County sits below the statewide county average of ~16 mills — among the lower property-tax counties in Florida. Your exact rate depends on your city and the special districts that cover your parcel.
Property Taxes by City in Collier County
Millage varies across Collier County because each city layers its own municipal rate on top of the county, school-board, and water-management levies. Communities such as Naples, Marco Island, and Immokalee can carry different combined rates, so two similarly priced homes in different parts of the county aren’t always taxed the same. For the exact rate on a specific parcel, use the Collier County Property Appraiser’s TRIM estimator.
How Are Collier County Property Taxes Calculated?
Florida uses one formula everywhere:
Taxable Value × Millage Rate ÷ 1,000 = Annual Property Tax

Homestead & Other Exemptions That Lower Your Bill
- Homestead exemption — up to $50,000 off the taxable value of your primary residence. File with the Collier County Property Appraiser by March 1.
- Save Our Homes — caps annual assessed-value increases at 3% once homesteaded, protecting long-term owners from market spikes (it resets to market value when the home sells).
- Senior, veteran, disability & widow(er) exemptions — additional reductions for qualifying homeowners, including a low-income senior exemption and total exemptions for certain disabled veterans.
- Portability — if you sell one Florida homestead and buy another, you may transfer up to $500,000 of your accumulated Save Our Homes savings.
Key 2026 Collier County Property Tax Dates

How to Appeal Your Collier County Property Taxes
If you believe your assessed value is too high — higher than what your home would sell for — you have the right to challenge it. In Florida the process runs through the county Value Adjustment Board (VAB), and it’s the same each year:
- Read your TRIM notice (mailed mid-August). It shows your proposed assessed value, exemptions, and estimated taxes — and the exact petition deadline.
- Call the Property Appraiser first. Many issues are fixed informally — ask the Collier County Property Appraiser to review your assessment and bring recent comparable sales or any errors in your property record (square footage, condition, etc.).
- File a VAB petition if it’s not resolved. File with the Collier County Value Adjustment Board (through the Clerk of the Circuit Court) by the deadline printed on your TRIM notice — typically about 25 days after it’s mailed (mid-September). There’s a small filing fee (about $15 per parcel).
- Assemble your evidence. Recent comparable sales below your assessed value, a private appraisal, photos of condition problems, or documented errors in the appraiser’s record all help.
- Attend the hearing. A special magistrate weighs your evidence against the appraiser’s. You can appear in person, by phone, or submit in writing.
- Get the decision. If the VAB lowers your assessed value, your tax bill drops proportionally — and, if homesteaded, Save Our Homes caps future increases.
Grounds that work: your assessed value exceeds market value, an exemption you qualify for was denied, or there’s a factual error in your property record. Filing does not require a lawyer or a paid service — you can petition the VAB yourself for the filing fee.
Paying your bill: Florida tax bills mail November 1, and paying that month earns a 4% discount, stepping down to 1% by February. See the Florida property tax discount schedule.

Bills mail around November 1 and are due by March 31, with early-payment discounts (4% Nov down to 1% Feb). They become delinquent April 1.
How do I lower my Collier County property taxes?
File for the homestead exemption (up to $50,000 off taxable value) by March 1, and apply any senior, veteran, or disability exemptions you qualify for. Save Our Homes then caps future increases at 3% a year.
Why did my taxes go up after I bought?
The property is reassessed to its sale price the January 1 after closing, so the prior owner’s Save Our Homes savings disappear and your bill resets higher. This is why estimating before you close matters.
