How Does Florida Property Tax Reassessment Work?
Quick Answer
When you buy a Florida home, the property gets reassessed at market value as of January 1 of the year following the sale. This means your property taxes can jump significantly from what the seller was paying — especially if they had a long-term homestead exemption holding down their assessed value under Save Our Homes.
Florida’s Save Our Homes cap limits annual assessment increases for homesteaded properties to 3% or the CPI, whichever is lower. But that protection does not transfer to a new buyer. Estimate your actual post-purchase tax bill before you close, not after.

Why Property Tax Reassessments Surprise Florida Buyers
Florida’s property tax system has a feature that creates a hidden cost trap for buyers: the assessed value on the seller’s tax bill is almost never what you’ll actually pay. Sellers who have owned their home for years — especially those with homestead exemptions — have had their assessed values kept artificially low by Save Our Homes. The moment you buy the property, that protection disappears and reassessment happens at market value.
In Sarasota and Manatee counties, this reassessment effect can be dramatic. A home that sold for $600,000 where the seller was paying taxes on a $320,000 assessed value will be reassessed to market value — potentially doubling the annual tax bill overnight for the new owner.
How Florida Property Assessment Works
Florida property is assessed by the county Property Appraiser every year as of January 1. For homesteaded properties, the Save Our Homes amendment caps annual assessment increases at 3% or the Consumer Price Index, whichever is lower. Over many years of ownership, this creates a large gap between assessed value and market value — called SOH savings or portability benefit.
When a property changes hands, the SOH cap resets. The Property Appraiser reassesses the property at its full market value as of January 1 of the year after the sale. If you bought in May 2025, you’d be reassessed at market value as of January 1, 2026.
The Homestead Exemption: What Buyers Need to Apply For
As a new Florida homeowner who occupies the property as your primary residence, you can apply for the homestead exemption — a $50,000 reduction in assessed value ($25,000 applied to all taxes, $25,000 applied to non-school district taxes). This reduces your tax bill but does not eliminate the reassessment effect.
To receive the homestead exemption for the 2026 tax year, you must apply with the county Property Appraiser by March 1, 2026. You must own the property and have it as your primary residence as of January 1, 2026. Applications in Sarasota County are filed with the Sarasota County Property Appraiser’s office.
Calculating Your Actual Post-Purchase Tax Bill
Here’s how to estimate what you’ll actually pay after purchasing a Florida home:
- Find the market value: The county Property Appraiser will assess at approximately your purchase price (for arm’s-length sales).
- Subtract the homestead exemption: Deduct $50,000 from assessed value if you qualify and apply.
- Apply the millage rate: Multiply the taxable value by the applicable millage rate. In unincorporated Sarasota County, the combined millage rate is approximately 11.47 mills (per $1,000 of taxable value). City of Sarasota is approximately 14.88 mills.
- Example: $600,000 purchase price — $50,000 homestead exemption = $550,000 taxable value. At 11.47 mills: $550,000 x 0.01147 = $6,309/year in unincorporated Sarasota County.
Portability: Moving Your SOH Benefit to a New Home
Florida allows homesteaded owners to transfer (“port”) their accumulated Save Our Homes benefit to a new Florida homestead — up to $500,000 in SOH savings. If you are selling your current Florida homestead and buying another, you may be able to significantly reduce the assessed value on the new property.
Portability must be applied for within 3 years of establishing the new homestead and is not automatic. Work with the Sarasota County Property Appraiser’s office to confirm your portability eligibility and the amount you can transfer.
Non-Homestead Properties: Investment and Vacation Homes
For properties that are not your primary residence — investment rentals, vacation homes, second homes — Florida does not limit annual assessment increases to 3%. Non-homestead properties are capped at 10% per year, but there is no homestead exemption available. This makes non-homestead properties more exposed to rising assessed values in hot markets like Sarasota.
How to Challenge a Florida Property Assessment
If you believe the Property Appraiser’s assessed value exceeds the market value of your home, you can file a petition with the Value Adjustment Board. Deadlines are tight — typically within 25 days of receiving the TRIM (Truth in Millage) notice, which arrives in August. Successful challenges require comparable sales data showing your assessment is above market.

Questions Clients Actually Ask
How much will my property taxes go up when I buy in Florida?
It depends on how long the seller has owned the home and how much market values have appreciated. If the seller had a homestead exemption for 15 years in a market that doubled, their assessed value could be roughly half their sale price. Your taxes will reset to full market value — effectively doubling their annual bill. Always calculate your own tax estimate from the purchase price, not the listing’s current taxes.
When is the deadline to apply for homestead exemption in Florida?
March 1 of the year for which you want the exemption. You must own the property and have it as your primary residence as of January 1 of that year. Miss the March 1 deadline and you wait a full year. In Sarasota County, applications are filed with the Sarasota County Property Appraiser.
What is Florida portability and do I qualify?
Portability lets Florida homesteaded owners transfer up to $500,000 of their Save Our Homes benefit to a new Florida homestead. If you’re selling a Florida home you’ve homesteaded and buying another in the state, you may carry a significant assessed-value reduction to your new home. Apply for portability within 3 years of establishing the new homestead.
Do property taxes in Sarasota County vary by city?
Yes. The millage rate you pay depends on where the property is located: unincorporated county, City of Sarasota, Venice, North Port, or another municipality. City of Sarasota properties pay a higher millage rate than unincorporated county properties. The county Property Appraiser’s website shows millage rates by location.
Can I fight a high property assessment in Sarasota?
Yes. If you believe the Property Appraiser’s market value exceeds what your property is actually worth, file a petition with the Value Adjustment Board within 25 days of receiving your TRIM notice (typically August). Bring comparable sales data. Many challenges succeed when backed by solid market evidence.
