How Do Florida Property Taxes Work for Buyers?

How Florida Property Taxes Are Calculated

Florida doesn’t have a state income tax, but it does have property taxes — and for most homeowners they’re the single largest recurring cost after the mortgage payment. Understanding how the system works before you close is the best way to avoid sticker shock.

The formula is straightforward:

(Assessed Value − Exemptions) × Millage Rate = Annual Tax Bill

Each piece of that formula has a wrinkle worth knowing.

Assessed Value vs. Market Value

Florida’s property appraiser sets the “just (market) value” of your home as of January 1 each year. From that, the appraiser applies any available exemptions and caps to arrive at a lower “taxable value.” The tax bill is then calculated on taxable value, not market value.

When a property sells, the just value is typically reset to the sale price — or close to it. This is the core reason why a new buyer almost always pays more in property taxes than the seller was paying: the seller had years of Save Our Homes protection holding down assessed value, and that protection doesn’t transfer with the deed (portability is a separate process — more on that below).

What Is a Millage Rate?

A millage rate is a tax per $1,000 of taxable value. One mill = $1 per $1,000. Rates are set by multiple overlapping taxing authorities — the county, the school board, any municipalities, and special districts such as CDDs (Community Development Districts) and water management districts.

The total rate on your TRIM notice is the sum of every applicable authority. Here’s how Sarasota and Manatee counties compare at the county and school district levels in 2026:

Taxing Authority	Sarasota County (mills)	Manatee County (mills)
County general fund	~3.34	~6.43
School district operating	~4.81	~4.76
School capital (voter-approved)	~0.50	~0.50
Typical combined total (unincorporated, no CDD)	~15–17 mills	~17–20 mills

Note: Rates include municipal, fire, EMS, and water management levies where applicable. CDD assessments — common in master-planned communities in both counties — are separate line items that can add $1,000–$4,000+ per year on top of ad valorem taxes.

On a $500,000 taxable value, 17 mills produces an $8,500 annual tax bill. At 20 mills, that’s $10,000. Run the math on your specific purchase price before you make an offer.

Homestead Exemption: $50,000 Off Your Taxable Value

If you occupy the property as your primary Florida residence on January 1 of the tax year, you qualify for the homestead exemption. It works in two layers:

• First $25,000 — reduces taxable value for all taxing authorities, including school taxes.
• Second $25,000 (on values between $50,000 and $75,000) — reduces taxable value for all authorities except school taxes.

The practical effect: a $500,000 assessed home with full homestead gets taxed as if it’s worth $450,000 for most purposes, and $475,000 for school taxes. At a blended 17-mill rate, that $50,000 reduction saves roughly $850 per year.

Deadline to apply: March 1 of the year in which you want the exemption to take effect. Miss March 1 and you wait another full year. Apply through the Sarasota County Property Appraiser (if the home is in Sarasota County) or the Manatee County Property Appraiser.

Save Our Homes Cap: 3% Assessment Limit

Once your homestead exemption is in place, the Save Our Homes (SOH) cap limits how much the property appraiser can increase your assessed value each year — a maximum of 3% or the rate of inflation (CPI), whichever is lower.

If property values in your neighborhood jump 12% in a given year, your assessed value still rises no more than 3%. Over a decade, this produces a significant gap between market value and assessed value, which is exactly what you see when you look at a long-time neighbor’s tax bill and wonder how they pay so little.

Critical timing point: The SOH cap does NOT apply until the second full tax year after you establish homestead. In year one, your assessed value is set at (or near) the sale price with no cap protection. Year two is when the 3% limit engages. Budget accordingly.

Portability: Taking Your SOH Savings With You

If you’re a Florida homeowner selling one homestead property and buying another in Florida, you can transfer up to $500,000 of your accumulated SOH benefit to the new home. This is called portability.

Here’s how it works:

• Your “portability benefit” is the difference between your current home’s just (market) value and its assessed value.
• You apply that benefit to reduce the assessed value of your new home, up to a $500,000 maximum transfer.
• You must apply for portability when you file for homestead on the new property.
• You must establish homestead on the new property within two tax years of selling the old one, or you lose the benefit.

Example: You sell a Sarasota home with a $600,000 market value and a $350,000 assessed value — that’s $250,000 of SOH savings. You buy a new home in Manatee County for $800,000. You can apply the $250,000 portability benefit, bringing your starting assessed value down to $550,000 instead of $800,000. At 18 mills, that’s a $4,500/year difference on day one.

Portability is one of the most underused tax tools for move-up buyers in Florida. Most people don’t realize they’re leaving thousands of dollars on the table.

The TRIM Notice: Read It Every August

Each August, Florida property appraisers mail a Truth in Millage (TRIM) notice to every property owner. This is not a bill — it’s a preview of your proposed taxes before the local governments finalize their budgets in September.

The TRIM notice shows:

• Your property’s just (market) value as of January 1
• Your assessed value (after SOH cap, if applicable)
• All exemptions applied
• Your taxable value
• Every taxing authority’s proposed millage rate
• The resulting proposed tax amount

The TRIM notice also includes the deadline to file a formal objection with the Value Adjustment Board if you believe your assessed value is too high. That window is usually 25 days from the date the notice is mailed — typically mid-August through mid-September. Most homeowners ignore this deadline and overpay for years.

The Year-2 Tax Ratchet: The Surprise Nobody Warns You About

Here’s a scenario that catches buyers off guard, especially in high-appreciation markets like Sarasota and Manatee counties.

You buy a home in 2026 for $650,000. The seller had owned it for 15 years with a $280,000 assessed value (SOH cap compounding at 3% for years while the market tripled). The seller’s annual tax bill was roughly $4,500. You budget $4,500.

Reality: your assessed value resets to ~$650,000 the moment the deed transfers. With homestead exemption applied, your taxable value is around $600,000. At a combined 17-mill rate, your bill is approximately $10,200 — more than double what the seller was paying.

Then in year two, if Sarasota property values rise another 8%, your assessed value can only go up 3% — but it’s going up 3% from $650,000, not from $280,000. The SOH protection is valuable over time, but it takes years to build.

The takeaway: always base your tax estimates on your own purchase price, not on what the current owner pays. Zillow and Redfin often display the seller’s tax bill, which is useless for budgeting your costs.

CDD Assessments: The Line Item Nobody Reads

Many newer communities in Sarasota and Manatee counties are built inside a Community Development District. CDDs issue bonds to finance infrastructure — roads, utilities, amenity centers — and recoup those costs through annual assessments that appear on the property tax bill.

CDD assessments are separate from the ad valorem (millage-based) taxes. They are not reduced by the homestead exemption. They are not capped by Save Our Homes. And they don’t go away when the bonds are paid off — the CDD typically transitions to ongoing maintenance assessments.

In some master-planned communities in Lakewood Ranch (Manatee County) and similar developments, CDD fees add $2,000–$5,000 or more per year to the tax bill. Always ask for the full tax bill breakdown — both ad valorem and non-ad valorem assessments — before closing.

What Clients Say About Team Renick

We bought two units from Mike and Eric and sold one over the last four years. One thing that made life much easier for us was how they understood our feelings and situation regarding pricing. They knew where the other party was coming from, which made the process faster without all the back and forth. Once the contract was signed, their staff was great; I literally had to do nothing other than decide what color pen to sign with. Eric wasn’t just out to make a sale; he was tremendously helpful to us. Every week, he checks our apartment without asking for money, and when we had a storm, he even moved our car to safety. It wasn’t just about the sale; he became a friend and helped us out after the sale, just because we don’t live here.

When we discuss Florida real estate our sentence always begins with “We have friends who sell real estate in Longboat Key “ . Mike and Eric didn’t start off as our personal friends but after working with them for three real estate transactions, we feel they are not just “ our local real estate professionals” , but our friends as well. Team Renick – Mike Renick and Eric Teoh combined their years of real estate experience with their knowledge of the Longboat Key/Sarasota marketplace guiding us through every step of the buying and selling process with ease. They are easy to talk to, always available and quick to respond to all our calls almost immediately. After the sale has been just as important as the sale itself, especially since we don’t live in Longboat Key full time, from simple tasks that only a friend would help with to answering involved real estate investment questions. We have recommended Mike and Eric to our family and friends, and recommend them to you. If we ever choose to buy or sell again they will be our first choice in real estate professionals.
