Learn moreOkaloosa County Millage
Okaloosa County's ad valorem millage rate has held at 3.8308 mills since 2017 -- flat for what county reporting describes as either the 8th or 9th consecutive year depending on the source, a minor discrepancy disclosed here rather than resolved arbitrarily. The county's Municipal Services Taxing Unit (MSTU) millage was slightly lowered from 0.299 to 0.288 mills for the current budget cycle. The county's typical total millage, including school and municipal portions layered on top, runs around 12.89 mills, and the FY2025-26 county budget of roughly $687 million is projected to generate about $117.8 million in gross ad valorem revenue, per Mid Bay News and getthecoast.com reporting.
City of Fort Walton Beach Municipal Millage
The Fort Walton Beach City Council set a tentative millage of 4.3282 mills for the FY2025-26 budget -- unchanged in rate from the prior year, but about 6.62% above the 4.0596-mill rollback rate, meaning rising property values (citywide taxable value grew about 9.71% to over $2.41 billion) will generate more revenue at the same nominal rate. The city's preliminary FY2025-26 budget totals $65.2 million, per Mid Bay News reporting on the council's budget votes.
Homeowners and Flood Insurance
Estimates for Fort Walton Beach homeowners insurance vary widely by source: Bridgeway Insurance cites a typical range of $1,800-$4,500 a year depending on a home's age, construction, roof condition, and coastal proximity; a separate estimate puts the average closer to $2,000 a year (well below Florida's statewide $4,400 average per Insure.com, 2025); and yet another source cites a much lower $1,006-$1,366 range. Statewide, Florida premiums rose 15-20% in 2025, though the Florida Office of Insurance Regulation reported early signs of 2026 rate relief and new-carrier market entry -- stabilization that does not guarantee a decrease for every homeowner, particularly coastal, older-roof, or prior-claim properties.
Flood Zones and Storm Surge
Okaloosa County sits directly in the Gulf hurricane strike zone, with many homes mapped in FEMA's high-risk Zone AE (1% annual flood chance); storm surge is the greatest flood threat to Fort Walton Beach specifically, with surge heights potentially reaching 10-20 feet along the most exposed coastal areas. Standard homeowners insurance excludes flood damage, and a separate flood policy is federally required for homes with a mortgage in a high-risk zone.
