The $500,000 Tax Break Most Florida Homeowners Don't Know They Can Take With Them
When Florida homeowners sell one home and buy another, many of them quietly lose a tax benefit worth tens of thousands of dollars — not because the law took it away, but because nobody told them to fill out a single form.
That form is DR-501T, and it lets you carry your "Save Our Homes" benefit from your old homestead to your new one.
A quick refresher on Save Our Homes
Once you claim Florida's homestead exemption on your primary residence, the Save Our Homes amendment caps the annual increase in your property's assessed value at 3% (or the change in the Consumer Price Index, whichever is lower). Market value can climb at whatever pace the market sets. Assessed value, the number your tax bill is actually based on, cannot.
Stay in the same home long enough and a gap opens between the two. That gap is your Save Our Homes benefit. In Southwest Florida, where market values have run hard for years, I regularly see clients sitting on $100,000, $250,000, even the full $500,000 statutory maximum.
What portability does
Sell the home and that benefit doesn't have to evaporate. Florida law lets you "port" up to $500,000 of accumulated Save Our Homes savings to your next Florida homestead. If you're upsizing to a home of equal or greater market value, you can transfer the entire amount up to the cap. If you're downsizing, you transfer a proportional share — your old assessed value divided by your old market value, applied to the new home's market value.
The result is a lower assessed value on the new home from day one, and a lower tax bill every year you live there.
The DR-501T form
To claim portability you have to actually ask for it. Filing for the homestead exemption on your new property using Form DR-501 is step one. Filing Form DR-501T, the Transfer of Homestead Assessment Difference, is step two, and it is not automatic. The property appraiser will not chase you down to remind you.
The deadline is March 1 of the tax year you want the transfer to take effect. You file with the property appraiser in the county where your new homestead sits, even if your previous homestead was in a different county.
The three-year window
Florida voters approved Amendment 5 in November 2020, which extended the portability window from two years to three. The clock runs from January 1 of the last year your previous home received the homestead exemption. Sell in 2026 and you have until January 1, 2029 to establish a new Florida homestead and port the benefit. Miss the window and the benefit is gone.
Where this gets missed
In my practice I see portability slip past people in a few predictable ways. The homeowner builds a new home and construction drags past the deadline. A couple divorces and neither spouse realizes they need Form DR-501TS to allocate the benefit between them before either can port. A surviving spouse downsizes and assumes the property appraiser will handle it. Snowbirds finally make Florida their permanent residence, sell the northern home, and don't realize the Florida exemption they had on their vacation property could have been carrying a benefit they were entitled to claim.
None of these are exotic situations. They are ordinary life events, and the cost of overlooking the form is real money every year for as long as you own the next home.
The takeaway
If you have owned a Florida homestead for more than a year or two and you are thinking about selling, moving, or building, ask your closing agent, your CPA, or your estate planning attorney about portability before the sale closes — and certainly before March 1 of the year after you establish your new homestead. The form is two pages. The savings can run into six figures over time.
If you'd like a second set of eyes on your situation, our office handles this question regularly as part of estate and elder law planning. A short call can confirm whether you have a benefit worth porting and whether the timing still works.
