Quick Answer: Treasure Island FL property taxes are calculated at a combined millage rate of approximately 18 to 22 mills for 2026, covering Pinellas County, the school board, the city, and other districts. On a $700,000 assessed value with homestead exemption, annual taxes are roughly $12,000 to $14,000. Florida's homestead exemption, Save Our Homes cap, and portability provisions provide significant long-term savings for primary residents.
How Treasure Island Property Taxes Are Calculated
Florida property taxes are calculated by multiplying the taxable value of a property by the combined millage rate and dividing by 1,000. One mill equals $1 per $1,000 of taxable value. The taxable value is the assessed value minus any applicable exemptions.
For a Treasure Island property:
- The Pinellas County Property Appraiser determines the just (market) value of your property as of January 1 each year.
- Any applicable exemptions (homestead, senior, veteran, disability) are subtracted to produce the taxable value.
- The taxable value is multiplied by the combined millage rate and divided by 1,000 to produce the annual tax bill.

Florida Homestead Exemption
Florida's homestead exemption is one of the most significant property tax benefits available in the state. To qualify, the property must be your primary residence as of January 1 of the tax year, and you must hold legal title to the property.
The exemption works in two tiers:
- First $25,000: Applies against all levying authorities, including the school board. This saves roughly $500 per year for every mill the school board charges.
- Second $25,000: Applies against all non-school levies only. On a combined 14-mill non-school rate, this saves an additional $350 per year.
Total annual savings from the full $50,000 exemption are typically $1,000 to $1,500 depending on the specific millage breakdown. Apply at the Pinellas County Property Appraiser's office by March 1 of the tax year. Applications are available at pinellaspao.org or in person at 315 Court Street, Clearwater, FL 33756.
Save Our Homes Cap
Once homestead exemption is in place, the Save Our Homes (SOH) cap limits annual increases in a property's assessed value. Each year, the Property Appraiser compares the just value of your property to the prior year's assessed value. Your new assessed value cannot exceed the lesser of: just value, or prior assessed value plus 3%, or prior assessed value plus the CPI increase (whichever of 3% or CPI is lower).
In a rising market, this creates a growing gap between just value and assessed value. A long-term Treasure Island homeowner who purchased in 2010 at $400,000 might now have a just value of $850,000 but an assessed value that has only increased 3% per year since purchase, creating a SOH benefit of potentially $200,000 to $300,000.
This benefit is lost when the property is sold. A new buyer will have their assessed value set at just value in the first year, then the SOH cap applies going forward once they establish homestead.
Portability: Transferring Your SOH Benefit
Florida's portability provision allows homestead owners to take their accumulated SOH benefit with them to a new Florida primary residence. The rules:
- The maximum transferable benefit is $500,000.
- You must have abandoned the prior homestead within the three years preceding January 1 of the tax year for the new property.
- You must apply for portability at the same time as you apply for homestead exemption on the new property.
- If your new property's just value is lower than your prior property's just value, the portability benefit is proportionally reduced.
Portability is particularly relevant for Treasure Island buyers who are relocating from other Florida communities. A buyer coming from a long-held homestead in St. Petersburg or Clearwater may be able to apply hundreds of thousands of dollars in SOH benefit to their new Treasure Island home, significantly reducing their first-year assessed value and tax bill.
Additional Exemptions
Senior Citizen Exemption
Low-income seniors (65 and older with household income below $35,167 for 2026, adjusted annually) may qualify for an additional local exemption up to $50,000 from county and city levies, but not from school levies. Apply at the Property Appraiser's office.
Veteran Disability Exemption
Veterans with a service-connected disability of 10% or more receive an additional exemption proportional to their disability rating. A 100% disabled veteran pays no property taxes. Surviving spouses of military personnel killed in action also qualify for exemption.
Widow/Widower Exemption
A $500 exemption is available to widows and widowers who have not remarried. It applies to all taxing authorities.

How to Appeal Your Property Assessment
If you believe the Pinellas County Property Appraiser has assessed your Treasure Island property above fair market value, you have the right to contest the assessment through the Value Adjustment Board (VAB).
Step 1: Review Your TRIM Notice
The TRIM (Truth in Millage) notice arrives in August and shows your proposed assessed value, exemptions, and estimated tax bill. Review it carefully when it arrives.
Step 2: Informal Conference
Before filing a formal petition, you can request an informal conference with the Property Appraiser's office. Many assessment disputes are resolved at this stage. Bring comparable sales data: closed sales of similar properties in the past 12 months in the same area and property type.
Step 3: File a VAB Petition
If the informal conference does not resolve the dispute, file a petition with the Pinellas County VAB. The filing deadline is typically 25 days from the date on the TRIM notice. The filing fee is $15 per parcel for residential properties. You will be assigned a hearing date.
Step 4: Attend the Hearing
At the hearing, you present comparable sales data, appraisal reports, or other evidence supporting a lower value. The special magistrate (an independent appraiser or attorney) reviews both your evidence and the Property Appraiser's data and issues a recommendation to the VAB.
