Palm Beach County Property Tax Portability for Relocating Buyers

A relocating buyer sits down with a listing sheet for a home in Palm Beach County. The tax line reads a few thousand dollars a year, lower than the buyer expected for a home at that price. The buyer's agent explains, gently, that the number belongs to the seller, not to them. The buyer nods, adjusts the budget slightly upward, and moves on.

That adjustment is usually too small. The gap between what the seller pays and what the buyer will pay has almost nothing to do with the home and everything to do with a Florida tax mechanic that resets at every sale, then partially un-resets for some buyers and not others, depending entirely on where they lived before they signed the contract.

The number on the sheet was never a promise

Florida's Save Our Homes law caps how fast a homesteaded property's assessed value can climb each year, at 3 percent or the rate of inflation, whichever is lower. A home bought decades ago can have a market value far above its assessed value, because the assessed side has been climbing on the capped track while the market climbed at whatever pace the neighborhood set. That gap is what makes a long-time owner's tax bill look modest next to a comparable listing two doors down.

The Palm Beach County Property Appraiser's own exemption rules are direct about what happens next. When ownership changes, the assessed value resets to market value. Any accumulated cap savings the seller built up are removed. A seller's homestead exemption can technically remain on the property through the rest of the calendar year of the sale, but it belongs to the seller, not the new owner, and it disappears as of January 1 of the following year. The buyer starts over.

This applies to every buyer. It is not a Florida-versus-out-of-state distinction. It is simply how the reset works. What differs by origin is what happens next.

Portability sounds like a fix. For out-of-state buyers, it isn't one at all

Florida does have a mechanism that lets a homeowner carry some of that accumulated benefit forward. It is called portability, and it lets a homesteaded owner transfer up to $500,000 of the gap between market and assessed value to a new Florida homestead. The filing is a separate form, DR-501T, submitted alongside the new homestead application, and the transfer has to happen within three tax years of giving up the old homestead, a window that was extended from two years by a 2020 constitutional change.

Here is the detail that changes the math for anyone relocating from outside Florida. Portability only moves between Florida homesteads. A buyer relocating from out of state can apply for Florida homestead once residency is established, the same as anyone else, but there is no prior Florida homestead to port anything from. The three-year window, the $500,000 cap, the DR-501T form, none of it is reachable for someone whose prior home was in Georgia, New York, or anywhere else outside the state.

That means two buyers can close on nearly identical homes in the same Palm Beach County zip code, at the same price, in the same month, and carry two entirely different tax trajectories going forward, for reasons that have nothing to do with either house.

The reset is identical for all three. The recovery is not. A buyer moving within Florida is rebuilding on top of years of prior protection. A buyer moving in from another state is starting the entire clock at zero, with the new home's full market value as the assessed value for year one, no exceptions.

Where you land inside the county moves the number again

The reset problem sits on top of a second variable that has nothing to do with Save Our Homes at all: which of Palm Beach County's municipalities the home sits in. The county contains dozens of separate taxing jurisdictions, and the combined millage, the county, school, city, and special district rates added together, differs by town. The Town of Palm Beach carries one of the county's lower effective rates, close to 1.49 percent. Other municipalities in the county, including Riviera Beach, run above 2.2 percent. Florida's statewide effective rate averages closer to 1.1 percent, for comparison.

On a multi-million-dollar purchase, the spread between a 1.49 percent town and a 2.2 percent town is tens of thousands of dollars a year, not a rounding error. On a more modest purchase, the same spread still moves the monthly number enough to matter for a mortgage qualification. A buyer comparing two towns on lifestyle alone, without checking which taxing authorities cover each parcel, is comparing incomplete numbers.

The clock the county just started

If you already own here, the mechanism above is not theoretical this week. Palm Beach County mails its Notice of Proposed Property Taxes, commonly called the TRIM notice, in mid-August, and it lands with the full picture: last year's assessed value, this year's proposed assessed value, and the market value the Property Appraiser is using as of January 1. For the 2026 tax year, the Value Adjustment Board's petition filing deadline is September 14, 2026, twenty five days after the notice goes out.

The Property Appraiser and the Clerk's office are both clear on one procedural point that trips people up. Calling the Property Appraiser's office for an informal review does not pause the 25-day clock. If there is any real question about the assessed value on that notice, the petition has to be filed before the deadline regardless of how those informal conversations are going. A filed petition can be withdrawn later if the informal review resolves things.

For a buyer under contract right now, the TRIM notice a seller just received is worth asking for directly. It shows the seller's current assessed value next to market value, which is the clearest illustration available of exactly how large a gap is about to disappear when the sale closes.

What November's ballot measure changes, and what it doesn't

Florida voters will decide on a constitutional amendment this November, the "Save Our Homes from Excessive Property Taxes" measure, which passed the Legislature during a June 2026 special session. If it clears the 60 percent threshold, the non-school homestead exemption rises from today's $50,000 to $150,000 starting January 1, 2027, then to $250,000 the following year, with inflation adjustments after that.

The amendment sits on top of the existing Save Our Homes cap and portability rules rather than replacing any part of them. It does not change the $500,000 portability ceiling, does not extend portability across state lines, and does not change the fact that assessed value resets to market at every sale. A separate proposal that would have removed the $500,000 portability cap entirely, HJR 211, died in the regular session and is not on this year's ballot. A relocating buyer waiting for November to solve the reset problem is waiting on the wrong measure.

Questions worth asking before you write an offer

1. Where did you last hold a Florida homestead, if anywhere, and can you document the assessed and market values on that property?
2. Which municipality, not just which county, will your new home sit in, and what is that municipality's combined millage?
3. Has the seller shared their most recent TRIM notice, and what does it show for market value versus assessed value?
4. If you do qualify for portability, is your new home purchase happening inside the three-tax-year window from when you gave up your prior Florida homestead?
5. Have you asked your lender to model your first full year of property tax at reset assessed value, rather than at the seller's current bill?

None of this is legal or tax advice, and a CPA or the Property Appraiser's own staff can confirm the specifics for a given parcel. But knowing which questions to ask before you're under contract is the difference between a budget built on the seller's number and one built on your own.
