Property Taxes and the True Cost of Owning on Siesta Key

Property Taxes

Siesta Key properties fall under Sarasota County jurisdiction. The millage rate includes county, school district, and special district levies. Florida's homestead exemption reduces taxable value by $50,000 for primary residences — a roughly $575/year savings. Non-homesteaded properties (investment or seasonal homes) do not receive this exemption and pay the full assessed value.

Insurance Adds Up Fast

Flood insurance runs $2,500–$6,000+ per year for most island properties. Windstorm insurance adds $3,000–$10,000+ annually for waterfront homes. Condo owners face HOA fees of $400–$1,200+ per month, which typically include the building's share of windstorm and hazard coverage.

Maintenance: The Coastal Premium

Maintenance costs on a barrier island run higher than mainland equivalents due to salt air corrosion, humidity, and storm exposure. Exterior paint, metal fixtures, HVAC systems, and roofing all have shorter useful lives.

The Total Picture

For a typical $850,000 Siesta Key condo as a primary residence: property taxes around $9,175 after homestead, HOA $7,200–$14,400, flood $3,000–$5,000, HO-6 $800–$1,500, plus miscellaneous maintenance and assessments. Annual carrying costs excluding mortgage routinely land in the $20,000–$30,000+ range.

Florida's Tax Advantages

Florida has no state income tax, no estate tax, and no inheritance tax. For high earners or retirees with substantial investment income, state income tax savings can partially or fully offset the higher insurance and property tax costs of barrier island living.
