Updated October 21, 2026: When buying a home in Naples or Marco Island, the seller's current property-tax bill may not predict what the new owner will pay. Florida assessment rules, homestead eligibility, Save Our Homes protection, portability and local taxing authorities can all affect the future bill.
Why the seller's tax bill may be misleading
A long-time Florida homeowner may have a homestead exemption and years of Save Our Homes assessment protection. According to the Collier County Property Appraiser, when a homesteaded property is sold or conveyed to a new owner, its assessed value generally becomes full market value for the new assessment cycle. If the new owner qualifies for homestead, the assessment-limitation process then begins for that owner.
This is why buyers should not simply copy the seller's annual tax amount into their long-term budget. A purchase can change the relationship between market value, assessed value and taxable value.
Three property values buyers should understand
- Just or market value: The property appraiser's estimate of value as of January 1, based on Florida appraisal requirements.
- Assessed value: The value after any applicable assessment limitations, including Save Our Homes for qualifying homestead property.
- Taxable value: The assessed value after applicable exemptions are subtracted. Different taxing authorities may calculate taxable value differently because some exemptions do not apply to every levy.
Property taxes are calculated from taxable value and the millage rates imposed by the applicable taxing authorities. Non-ad valorem assessments can also appear on a tax bill and are not calculated from property value in the same way.
Florida homestead exemption basics
The Florida Department of Revenue states that someone who owns a Florida property and makes it a permanent residence, or the permanent residence of a dependent, may qualify for a homestead exemption that reduces taxable value by as much as $50,000 under the general statewide framework.
The first $25,000 generally applies to all property taxes, including school district taxes. The additional exemption applies to assessed value above the statutory threshold and generally does not apply to school district levies. Eligibility and the exact benefit are determined by the county property appraiser.
For a new Florida homestead, the owner must meet the applicable ownership and permanent-residence requirements as of January 1 and file with the county property appraiser. The regular timely filing deadline is March 1.
What Save Our Homes actually limits
Save Our Homes does not cap the tax bill itself. It limits annual increases in the assessed value of qualifying homestead property. Florida law generally limits the annual assessment increase to the lower of 3 percent or the applicable change in the Consumer Price Index, subject to statutory exceptions.
Millage changes, new construction, added improvements, changes in exemptions and non-ad valorem assessments can still affect the amount due. The Collier County Save Our Homes FAQ specifically explains that the cap applies to assessed value, not directly to taxes paid.
How portability may help Florida homeowners who move
Florida portability can allow an eligible homeowner to transfer all or part of the Save Our Homes assessment difference from a previous Florida homestead to a new Florida homestead. The maximum transferable benefit is generally $500,000, subject to eligibility and the calculation required when moving to a higher- or lower-valued home.
The Florida Department of Revenue explains that the new homestead generally must be established within three years of January 1 of the year the prior homestead was abandoned. The owner must also file the portability application with the new homestead application. The regular filing deadline is March 1 of the first year after the move.
Portability calculations can become more complicated when ownership is shared, spouses combine separate homesteads, owners separate into different homes or the new property has a lower value. Buyers should request a property-specific determination from the Collier County Property Appraiser rather than assuming the full amount will transfer.
A practical tax-planning checklist for buyers
- Review the parcel record. Confirm the property's current market, assessed and taxable values and identify existing exemptions.
- Do not use the seller's bill as your only estimate. Ask how a change in ownership could affect the next assessment.
- Identify all taxing components. Review both ad valorem taxes and non-ad valorem assessments shown on the bill.
- Check homestead eligibility early. If the home will be your permanent Florida residence, review filing requirements before the March 1 deadline.
- Ask about portability. If you are moving from another Florida homestead, gather the prior parcel information and discuss the potential transfer with the property appraiser.
- Build a conservative housing budget. Include property taxes, homeowners and flood insurance where applicable, association charges, CDD assessments, maintenance and utilities.
What sellers should know
Sellers should avoid promising that a buyer will receive the same tax treatment or annual bill. The existing bill reflects the current owner's assessment history and exemptions. A buyer's future taxes depend on the new assessment, eligibility, exemptions, millage rates and any applicable portability benefit.
When marketing a Naples or Marco Island home, providing accurate parcel information can help buyers ask better questions, but the county property appraiser and tax collector remain the authoritative sources for assessment and billing information.
Frequently asked questions
Will my property taxes equal the seller's current taxes?
Not necessarily. A change in ownership can cause the assessed value to reset toward market value for the next assessment cycle. Your exemptions and portability eligibility may also differ from the seller's.
Does the Save Our Homes cap mean taxes can rise only 3 percent?
No. The limitation generally applies to assessed value, not directly to the tax bill. Millage rates, improvements, exemptions and non-ad valorem assessments can affect the final amount.
Can I transfer my homestead exemption to another Florida home?
The exemption itself is not transferred. An eligible homeowner may be able to transfer, or port, all or part of the Save Our Homes assessment difference to a new Florida homestead.
Where should I verify Collier County property-tax information?
Use the Collier County Property Appraiser for parcel values, exemptions and assessment questions. Tax bills and payment information are handled by the appropriate tax collector.
