How Are Property Taxes Calculated on Siesta Key?
Florida property taxes are calculated by multiplying the assessed value by the applicable millage rate, then subtracting any exemptions. Siesta Key is unincorporated Sarasota County, so you pay the county millage rate (there is no additional city millage). The Sarasota County Property Appraiser determines the assessed value of your property based on market data. The Value Adjustment Board hears appeals.
Sarasota County Millage Breakdown (Unincorporated, Approximate)

Note: Millage rates are set annually by each taxing authority and can change. The figures above are approximate based on recent years. Verify current rates with the Sarasota County Property Appraiser's office before closing. Taxing authorities set new millage each fall for the following year.

Does the Homestead Exemption Apply on Siesta Key?
Most Siesta Key property owners do not qualify for Florida's homestead exemption because the property is not their primary residence. Homestead requires that the property be your permanent residence as of January 1 of the tax year, supported by Florida driver's license, voter registration (if registered), and a Declaration of Domicile filed with the Clerk of Courts.
If you do establish Siesta Key as your primary residence, the homestead exemption provides a $50,000 reduction in assessed value (first $25,000 applies to all tax rates; second $25,000 applies to non-school millage). At a combined rate of approximately 13.5 mills, this saves approximately $550-$600 per year (because the full exemption does not reduce school district taxes). The more significant benefit is the Save Our Homes cap.
Save Our Homes Cap and How It Works
Once you establish homestead, the Florida Save Our Homes (SOH) amendment limits your annual property tax assessment increase to 3% or the rate of CPI inflation, whichever is lower. Over 10-15 years in a rising market, this creates a substantial gap between your assessed value and market value, significantly reducing your tax bill relative to a new buyer.
Example: If you buy a Siesta Key home for $2M as your primary residence and establish homestead, your assessment is capped at 3% growth per year. After 10 years in a market where values grew 5-7% annually, your assessed value might be $2.5M while market value is $3.5M, saving you $13,500+ per year in taxes versus a new buyer assessed at market.
When you sell, the new buyer loses the SOH cap and is assessed at the new market value. SOH savings are transferable to a new Florida homestead via portability within three years.

What is the property tax rate on Siesta Key?
Siesta Key is in unincorporated Sarasota County. The combined millage rate for unincorporated Sarasota County properties is approximately 13.0-14.0 mills total (county general, school district, fire, mosquito control, and other special districts). At 13.5 mills, the effective rate on a $1M home without homestead exemption is approximately $13,500/year, or about $1,125/month.
Does the homestead exemption apply on Siesta Key?
The Florida homestead exemption applies to primary residences only. Because the majority of Siesta Key homes are second homes, vacation properties, or investment rentals, most owners do not qualify. If Siesta Key is your permanent primary residence (Florida voter registration, driver's license, and declaration of domicile all pointing to Siesta Key), you can apply for the $50,000 homestead exemption and the Save Our Homes 3% annual cap.
When do I need to apply for the homestead exemption?
The deadline to apply for Florida homestead exemption is March 1 of the tax year in which you want the exemption. You must own the property and establish it as your primary residence by January 1 of that year. Apply with the Sarasota County Property Appraiser's office.
What is Save Our Homes and how does it affect Siesta Key owners?
Save Our Homes (SOH) is a Florida constitutional amendment that caps annual property tax assessment increases at 3% or the rate of inflation (whichever is lower) for homesteaded properties. Over years, this creates a gap between the assessed value and market value. When you sell and buy again, the new owner loses the SOH cap. Portability allows you to transfer accumulated SOH savings to a new Florida homestead within three years of selling.
How do Siesta Key property taxes compare to other Florida barrier islands?
Sarasota County's millage rates are moderate compared to some coastal Florida counties. Properties in unincorporated Sarasota County pay approximately 13.0-14.0 mills. Properties in Pinellas County barrier island communities (St. Pete Beach, Indian Shores, Clearwater Beach) often pay 15-19+ mills, so Sarasota County's rate is comparatively lower on a mill-for-mill basis, though property values on Siesta Key are very high, which drives the absolute tax dollar amounts.
