See your real year-1 property tax in Santa Rosa County at purchase, not the seller's capped bill, and how much you would save if Governor DeSantis’s proposed $250,000 homestead exemption passes. Santa Rosa County's 2025 total millage runs about 12.81 mills.
Santa Rosa County sits in Panhandle. Its 2025 total millage is about 12.81 mills, of which roughly 5.38 mills fund schools and the rest covers county, city, and special-district services. On a homesteaded $350,000 home with the standard $50,000 exemption, that lands near $3,976 a year, about $331 a month. The millage figure is the Florida TaxWatch 2025 county average, so treat it as a close estimate rather than an exact rate. The bill moves with your purchase price, the city you buy in, and any CDD or special-district millage, so treat it as a close estimate and run your own number above.
The number that trips up Santa Rosa County buyers is the seller's tax line on the listing. A long-time owner has years of Save Our Homes protection holding their assessed value below market, so their bill looks low. When you take ownership that cap resets to what you paid, and your first bill is usually higher. Pricing your carrying cost off the seller's old tax is one of the most common Florida buying mistakes.
Under the proposed exemption, the non-school portion of a $350,000 Santa Rosa County bill would fall by about $1,485 a year, leaving $2,491. School taxes of about 5.38 mills stay in place, which is why the bill does not reach zero. The amendment (CS/HJR 1F) passed the Legislature on June 2, 2026 and goes to voters in November 2026, where it needs 60% to pass. The exemption phases in at $150,000 for 2027 and $250,000 for 2028, and new residents who establish Florida residency after December 31, 2026 wait five years for the full amount. See both phases for any price in the Florida amendment calculator, and price your home on today's real bill, treating the savings as upside.
The savings above are real for you. They are also revenue Santa Rosa County stops collecting. Each homesteaded $350,000 home that takes the full exemption removes about $1,485 a year from the Santa Rosa County non-school tax base, at the county’s non-school rate of about 7.43 mills. The amendment protects school funding, so the gap falls on county and city services like police, fire, parks, and roads. Statewide the Florida House staff analysis puts the reduction at about $4.6 billion in the first year, growing to about $8.4 billion a year at full phase-in.

Two costs sit outside the millage math. The school district levies the school portion of every bill in the county. Master-planned and newer communities can add CDD or special-district assessments, often $1,000 to $2,500 a year, billed on the same statement, and some cities carry their own additional millage on top of the county rate. Layer homeowners insurance and any HOA dues on top of all of it for a true monthly carrying cost. Our CDD and carrying cost calculator totals it, and the mortgage payment calculator folds the tax into a full monthly payment.
