Florida's Save Our Homes Cap: The Tax Reset Hiding in the Seller's Low Bill

Florida listings love to brag about a low tax bill, and in a long-owned home that bill is real — for the seller. It is also the single most misleading number in the listing, because the discount behind it is personal to the seller, not attached to the house. The mechanism is called Save Our Homes, and the day the home sells, it stops applying.

In Florida, the seller's low tax bill does not transfer. Save Our Homes caps a homesteaded owner's assessed value growth at 3% a year, but a sale resets the assessment to full market value on January 1 — so budget from the purchase price, not the seller's bill, and file homestead by March 1.

How Save Our Homes builds the gap

Florida county property appraisers set each home's just (market) value every January 1. For an owner who has filed homestead exemption on a primary residence, the Save Our Homes cap then limits how fast the assessed value — the number the tax is actually calculated on — can rise: 3% a year or the change in the Consumer Price Index, whichever is lower. In a market where values climb faster than 3%, the assessed value falls further behind the just value every year the owner stays.

Homestead also takes value off the bill directly: a $25,000 exemption against all levies, plus an additional exemption of up to $25,000 — $26,411 for 2026, inflation-adjusted — on value above $50,000 for non-school levies. The filing deadline is March 1. Stack a decade or two of capped growth on top of those exemptions and a seller can be paying tax on a fraction of what their house is worth. That fraction is the trap: none of the cap benefit is the house's. It belongs to the seller's tenure, and it ends at the closing table.

What happens the year you buy

A sale resets the assessment. The property appraiser re-bases the home toward its full just value, and your first full tax bill is calculated on that reset value — minus whatever homestead exemption you file for yourself, with your own Save Our Homes cap starting from zero. This is the Florida version of the national pattern we document in the property-tax reset every buyer should expect: the seller's bill is history, not a forecast.

The practical damage usually arrives through escrow. If your lender sets the monthly escrow deposit from the seller's capped bill — a common shortcut — the first reset bill creates a shortage, and your payment jumps in year two to cover both the higher bill and the shortfall. Buyers experience that as a surprise. It is printed in the county record before you ever make an offer: just compare the home's just value to its assessed value. The gap between those two numbers is, roughly, the tax increase already scheduled for the next owner.

Worked example 1: a 30-year hold in West Palm Beach

One West Palm Beach home in our report files (354 Edmor Road, ZIP 33405) last changed hands in August 1995 for $84,000. Three decades of Save Our Homes did the rest. The county's 2025 figures: just value $579,685, assessed value $133,611 — the seller was taxed on 23% of the home's county market value. The seller's actual bills tell the story: $2,016 in 2023, $2,084 in 2024, $2,162 in 2025.

Our report's buyer estimate for the same address, labeled an estimate in the report itself: $18,000–$22,000 a year after reassessment toward market value at the combined city/county millage on the expected purchase value. That is roughly ten times the seller's bill, on the same house, with nothing about the house changing. Every dollar of that difference was visible in the county record — assessed value vs. just value — before an offer was written.

Sources: Palm Beach County Property Appraiser records as compiled in the address's CurbFacts report file (parcel record, 2025 values and 2023–2025 tax history, checked November 2026). The buyer figure is the report's labeled estimate, not a county quote.

Worked example 2: the same reset at a starter-home price

The reset is not a luxury-home problem. A second Palm Beach County report file (5377 Gene Circle, ZIP 33415, last sold in 2000) shows the seller paying $3,890 a year on a Save Our Homes-capped assessment of $168,022 against a county just value of $263,708. The report's buyer tax budget for that address: an estimated $4,800–$6,200 a year — a 23% to 59% increase over the seller's bill, labeled an estimate, on a home listed under $400,000. Smaller numbers, same mechanism, and the increase lands on buyers with the least room in their monthly budget to absorb it.

How to size up any Florida listing in five minutes

• Find the county property appraiser's page for the parcel. Our Palm Beach County records guide routes to the right offices; every Florida county publishes just value and assessed value side by side.
• Subtract. Assessed value subtracted from just value is the seller's accumulated cap benefit — the amount your assessment is scheduled to climb toward. A small gap means a small reset. A six-figure gap means the listing's tax line is fiction for you.
• Budget from value, not from the seller's bill. Apply the local millage to a value near the purchase price, subtract the homestead exemptions you will qualify for, and treat the result as an estimate until the appraiser confirms it in writing.
• File homestead the week you close — the deadline is March 1, and filing is also what starts your own Save Our Homes cap. Our step-by-step: homestead exemption — file it the week you close.
• Check where Florida sits nationally. Florida is one of the full-reset states in our 50-state roundup, which states reset property taxes at sale — worth reading if you are comparing a Florida purchase against a home in a cycle-based state.

The rest of the Florida record file — flood zone vs. the listing, disclosure duties, registry, permits — is gathered in the Florida records guide and the Florida seller disclosure guide. Every CurbFacts report runs this same just-vs.-assessed comparison for the address and prints the reset estimate with its sources, the way the two cases above were built. You can see the format in the sample report, or run your own address through the free preview.

FAQ

Does the seller's Save Our Homes cap transfer to the buyer?

No. The cap is tied to the seller's homestead. When the home sells, the assessment resets toward full just (market) value, and the buyer's own cap only begins once the buyer files homestead and the capped years start accumulating.

How big can the Florida tax reset be?

It depends on how long the seller held the home and how fast values rose. In one documented Palm Beach County case, the seller paid $2,162 on a $133,611 assessed value against a $579,685 just value, and the buyer's estimated bill was $18,000–$22,000 a year. Long tenure plus a hot market is where the extreme gaps live.

When do I file for homestead exemption in Florida?

By March 1, for a home you own and occupy as your permanent residence. File as soon as you close rather than waiting for the deadline — filing activates both the exemption (a $25,000 exemption, plus up to $26,411 for 2026 on value above $50,000 for non-school levies) and your Save Our Homes cap.

Why did my mortgage payment jump a year after I bought in Florida?

Most likely escrow. If the lender based your escrow deposits on the seller's capped tax bill, the first reset bill creates a shortage, and the lender raises the monthly payment to cover the new bill plus the shortfall. The reset itself was predictable from the county's just value vs. assessed value before you bought.

Where can I see a home's just value and assessed value?

On the county property appraiser's website — every Florida county publishes both figures per parcel, free. The assessed value is what the current owner is taxed on; the just value is the county's market value, and the gap between them is the reset waiting for the next buyer.
