A buyer closes on a home. The closing disclosure shows a property tax line that looks manageable because it reflects what the seller paid, often under a homestead exemption they held for a decade. Eleven months later, the buyer opens their first Truth in Millage (TRIM) notice, and the number has nearly doubled. Nothing went wrong procedurally. The disclosure that warned them was buried in Paragraph 10 of the contract they signed, worded almost exactly like a statute because that’s precisely what it is.
This is one of the more predictable sources of post-closing buyer frustration in Florida real estate, and it has almost nothing to do with the transaction itself. It’s a structural feature of how Florida taxes homesteaded property, and understanding it separates an agent who can explain a tax bill from one who gets a confused phone call the following January.
What the Statute Actually Requires
Florida Statute 689.261 requires that every prospective buyer of residential property receive a Property Tax Disclosure Summary at or before signing the contract. In the FAR/BAR contract, this isn’t a separate form; the required language is built directly into the contract itself, which is why most agents have seen the wording without necessarily registering its significance. In substance, it states that the buyer should not rely on the seller’s current property taxes as an indication of what the buyer will owe the following year, because a change of ownership triggers reassessment.
That single sentence is doing a lot of quiet work. It exists because Florida’s property tax system does something most buyers, and more than a few agents, don’t fully anticipate: it decouples the assessed value used for taxation from the market value of the home, but only for as long as the same owner keeps the homestead exemption in place.
The Mechanism Behind the Surprise
Under Florida Statute 193.155, once a homeowner has a homestead exemption, the assessed value of their property can increase by no more than 3% per year, or the change in the Consumer Price Index, whichever is lower. This is the Save Our Homes cap, created by a 1992 constitutional amendment. Over years of ownership, especially in a market where home values have appreciated quickly, the gap between assessed value and actual market value can become substantial. A home might carry a market value of $650,000 while its assessed value, frozen for tax purposes over a decade of 3% annual caps, sits closer to $400,000.
That gap doesn’t transfer with the deed. When the property sells, the assessed value resets to full market value for the new owner. The cap doesn’t reappear until the new owner applies for and receives their own homestead exemption, and even then, it only limits future increases; it doesn’t restore the discount the previous owner had accumulated. Non-homestead property follows a parallel but separate rule under Florida Statute 193.1554, capping annual increases at 10% rather than 3%, which produces a smaller version of the same effect.
The result is mathematically simple but easy to miss in the moment: the tax bill a buyer sees reflected in the seller’s most recent bill, or prorated at closing, is often not close to what the buyer will actually owe once the county reassesses the property under new ownership.
Where This Becomes a Real Problem
Consider a buyer purchasing a long-held homestead property from a seller who bought it fifteen years earlier. At closing, taxes are prorated based on the seller’s current assessed value; a routine, correct step required under the contract. The buyer, working from that prorated figure and the seller’s most recent tax bill, budgets their monthly payment accordingly, including in a mortgage pre-approval that assumed taxes near that number.
The following year, the county reassesses at market value. The buyer’s TRIM notice arrives showing a significant increase, sometimes changing the effective monthly payment by several hundred dollars once escrow reprojects. For a buyer operating close to their debt-to-income ceiling, that shift isn’t cosmetic, it can affect refinancing plans, household budgeting, or in some cases, whether the loan remains comfortably affordable.
None of this violates the contract. The Property Tax Disclosure Summary language was there, in writing, exactly as the statute requires. But a disclosure that’s technically present and a disclosure that’s actually understood are two different things, and the difference shows up in the phone call an agent gets eleven months after closing.
What an Informed Agent Does Differently
The disclosure satisfies the legal requirement. It doesn’t, by itself, prepare a buyer for the number they’ll actually see. An agent who understands how Save Our Homes and the 10% non-homestead cap function can do something the statute doesn’t require but the buyer genuinely needs: give a realistic estimate of post-sale taxes, using the county property appraiser’s site to check what the new assessed value would likely be at market rate, rather than letting the buyer anchor on the seller’s number.
This matters even more in transactions where the buyer is relocating from out of state and has no prior frame of reference for how Florida’s assessment system works, or where the seller’s tax bill is unusually low due to long-term ownership. In both cases, the gap between “what the closing statement shows” and “what the buyer will actually pay” tends to be largest, and the disappointment sharpest, if no one flags it in advance.
Agents representing sellers with substantial Save Our Homes benefits should also be aware of portability: under a 2020 constitutional amendment, a homesteaded seller who buys a new Florida homestead within three years can transfer some or all of their accumulated Save Our Homes benefit to the new property. That’s a separate conversation from the buyer-side disclosure, but it’s often relevant in the same transaction, and agents who understand both sides are better positioned to have a more complete conversation with both parties.
The CCC Connection
The Property Tax Disclosure Summary is one line of contract language most agents read past without a second thought. Understanding what sits behind it, the mechanics of Save Our Homes, the non-homestead cap, and how reassessment plays out after a sale, is the kind of contract literacy that keeps a transaction from turning into a difficult conversation months later. Inside CCC Society, Tiffany and Natalie walk through disclosures like this one in the context of real transactions, not just statute text, so agents understand not only what the contract requires, but what it actually means for the people signing it.
Frequently Asked Questions
Why does a home’s property tax bill change after it’s sold?
Florida’s Save Our Homes cap limits annual assessed value increases to 3% (or CPI, whichever is lower) for homesteaded property, but only while the same owner holds the exemption. When the property sells, the assessed value resets to full market value, which is often significantly higher than the prior owner’s capped assessment.
Is the Property Tax Disclosure Summary a separate document?
Not usually. Under Florida Statute 689.261, the required disclosure language can be built directly into the sales contract rather than provided as a standalone form, and the FAR/BAR contract includes it this way.
Does the non-homestead cap work the same way?
Similarly, but not identically. Non-homestead property is capped at a 10% annual increase in assessed value under Florida Statute 193.1554, compared to 3% for homesteaded property, so the reassessment gap after a sale is typically smaller but still meaningful.
Can a seller transfer their Save Our Homes savings to a new home?
Yes, within limits. Portability rules allow a homesteaded seller to transfer some or all of their accumulated Save Our Homes benefit to a new Florida homestead property, provided they establish the new homestead within three years of leaving the old one.
How can an agent estimate a buyer’s actual post-sale tax bill?
By checking the county property appraiser’s website for the property’s current market value and applying the local millage rate, rather than relying on the seller’s existing tax bill, which reflects the seller’s capped assessment, not what the buyer will be assessed.
