Property tax in Naples, FL is set by stacking the millage rates of Collier County, the City of Naples (if you’re inside city limits), the Collier County School Board, the South Florida Water Management District, and any special districts that cover your parcel, then applying that combined rate to your property’s assessed value after exemptions. One mill equals one dollar of tax per $1,000 of taxable value.1Collier County Tax Collector. Real Estate For fiscal year 2026, Collier County’s own aggregate millage is roughly 3.77 mills before the other authorities are added on.2Collier County Government. FY 2026 Final Budget Public Hearing Two homes a few blocks apart can carry different total rates depending on which districts overlap.
How Your Bill Is Calculated
The Collier County Property Appraiser sets your property’s just (market) value as of January 1 each year. Exemptions come off that figure to produce taxable value, and the combined millage rate is applied to the result. A $300,000 taxable value at a combined 10.0 mills works out to $3,000.
In August, you’ll receive a Truth in Millage (TRIM) notice from the appraiser’s office. It lists each taxing authority’s proposed rate, shows your estimated tax, and tells you when and where each authority holds its budget hearing so you can speak before rates become final.3Florida Dept. of Revenue. Truth in Millage (TRIM) School board hearings typically run into September.4Collier County Public Schools. School Tax Information The TRIM notice is also the first chance to spot a valuation you disagree with.
Homestead Exemption
If the Naples property is your permanent residence as of January 1, the homestead exemption reduces its taxable value by up to $50,000. The structure is quirky. The first $25,000 of assessed value is fully exempt from all property taxes. The next $25,000 (from $25,001 to $50,000) gets no exemption. A second $25,000 then kicks in above $50,000, but that portion applies only to non-school taxes.5Florida Legislature. Florida Code 196.031 – Exemption of Homesteads For most Naples homes, which are assessed well above $75,000, the practical result is $25,000 off everything and another $25,000 off everything except school district levies.
Apply with the Collier County Property Appraiser on form DR-501 by March 1. The form asks for your Florida driver’s license or ID number, Florida vehicle tag number, Social Security number, voter registration if you’re a U.S. citizen, and proof that your declared domicile matches the property address.6Florida Department of Revenue. DR-501 – Original Application for Homestead and Related Tax Exemptions Late applications are accepted until the tax rolls are certified, but approval isn’t guaranteed.
Other Exemptions Worth Checking
Several additional exemptions stack on top of the standard homestead benefit. Most share the March 1 deadline, and each needs its own application.
Seniors 65 and Older
Owners 65 and up whose household income falls below an annually adjusted threshold (originally $20,000, raised each year for inflation) may qualify for an added exemption of up to $50,000. The exemption must be authorized locally by Collier County or the City of Naples.7FindLaw. Florida Code 196.075 – Additional Homestead Exemption for Persons 65 and Older A second version can eliminate property tax entirely for seniors 65 and older who have owned and lived in the homestead for at least 25 years, had a just value under $250,000 when they first qualified, and meet the income limit.
Disabled Veterans
Veterans with a service-connected total and permanent disability certified by the U.S. Department of Veterans Affairs receive a complete homestead exemption.8Florida Legislature. Florida Code 196.081 – Exemption for Certain Permanently and Totally Disabled Veterans and for Surviving Spouses of Veterans A surviving spouse keeps it while holding title, living in the home, and not remarrying, and can transfer the exemption amount to a new primary residence after a sale.
Surviving Spouses of First Responders
The surviving spouse of a first responder killed in the line of duty qualifies for a total homestead exemption, continuing as long as the spouse does not remarry and uses the property as a permanent residence.8Florida Legislature. Florida Code 196.081 – Exemption for Certain Permanently and Totally Disabled Veterans and for Surviving Spouses of Veterans
Disability Exemptions
Florida residents who are quadriplegic, paraplegic, hemiplegic, legally blind, or permanently confined to a wheelchair may qualify for a full homestead exemption, with income limits on some categories. A separate $5,000 exemption is available to residents certified by a licensed physician as totally and permanently disabled who don’t fall into those categories. Physician certification is required, and the March 1 deadline applies.
Save Our Homes: The Assessment Cap
Once you have the homestead exemption, your assessed value cannot rise by more than 3% a year or the change in the Consumer Price Index, whichever is lower.9Florida Legislature. Florida Code 193.155 – Homestead Assessments In a market where Naples values can jump sharply in a single year, that cap steadily opens a gap between assessed value and market value, and long-term owners end up with tax bills that look nothing like what a new buyer across the street pays.
The accumulated savings reset at a sale. The new owner’s assessed value resets to full market value as of the next January 1, and the cap starts over.9Florida Legislature. Florida Code 193.155 – Homestead Assessments If you’re buying, don’t estimate your bill from what the seller was paying. Ask for current assessed value and run the math against market value.
If you’re moving within Florida, you can carry up to $500,000 of Save Our Homes savings to a new primary residence. File DR-501T with your new homestead application by March 1 of the year you want it to apply. You have up to three tax years after abandoning the old homestead to use the transfer. Downsizing reduces the transferred amount proportionally rather than applying it dollar for dollar.9Florida Legislature. Florida Code 193.155 – Homestead Assessments
Investment properties, second homes, and commercial real estate don’t get the 3% cap, but non-homestead property is held to a 10% annual increase in assessed value, which also resets at sale.10Florida Legislature. Florida Code 193.1554 – Assessment of Nonhomestead Residential Property
Non-Ad Valorem Charges on the Same Bill
Your Collier County tax bill isn’t only property tax. Non-ad valorem assessments are flat charges for specific services and don’t depend on value. In Collier County, that typically includes solid waste collection and disposal, stormwater management, street lighting, and fire rescue. Solid waste alone runs roughly $256 per residential unit, with a not-to-exceed cap of $330 through 2029.11Collier County Government. Solid Waste Mandatory Collection and Disposal Non-Ad Valorem Assessment FAQ These charges are collected with your property taxes, and skipping them has the same consequences as skipping taxes.

What Happens If You Don’t Pay
Delinquent taxes trigger a 3% penalty on April 1, and the balance is a first lien on your property, ahead of your mortgage and every other lien.17Florida Legislature. Florida Code 197.122 – Property Taxes, a First Lien In May, the tax collector advertises delinquent properties in the local paper. By June 1, a tax certificate sale is held, where investors bid for the right to pay your delinquent taxes in exchange for a lien that accrues interest. Bidding starts at 18% annual interest and moves downward, with the certificate going to whoever accepts the lowest rate; if nobody bids, the county takes the certificate at 18%.18Florida Senate. Florida Code 197.432 – Sale of Tax Certificates After two years, the certificate holder can apply for a tax deed, which can end in loss of the property. In a market like Naples, delinquent parcels draw aggressive bidders.
Challenging Your Assessment
If you think the Property Appraiser overvalued your home, you can petition the Collier County Value Adjustment Board.19Collier Clerk of the Circuit Court & Comptroller. Collier County Value Adjustment Board – The 2025 Tax Year File a petition with the Clerk of the Circuit Court along with a filing fee of up to $50 per parcel.20Florida Legislature. Florida Code 194.013 – Filing Fees for Petitions There’s no fee for appealing a denied homestead exemption.
A special magistrate hears evidence from you and from the appraiser and decides whether the assessed value reflects fair market value as of January 1. Useful evidence includes comparable sales, a recent independent appraisal, and documentation of defects that affect value. Written decisions must be issued within 20 calendar days after the board’s final session, delivered by mail or electronically depending on what you selected when you filed.21Florida Legislature. Florida Code 194.034 – Hearing Procedures and Decision of the Value Adjustment Board A reduction is reflected on the tax roll before your final bill goes out.
