Florida Homestead Exemption and Save Our Homes Portability, Worked End to End: What Tampa Bay Move-Up and Downsize Owners Need to File by March 1

How does Save Our Homes portability work when you move within Florida?

Florida lets you transfer — “port” — up to $500,000 of your accumulated Save Our Homes tax savings from one Florida homestead to the next. You file Form DR-501T alongside your new homestead application (Form DR-501) with the property appraiser in your new county, and you must establish the new homestead within three tax years of giving up the old one. If you're buying a higher-priced home, the full differential moves with you up to the cap. If you're downsizing, a proportional share transfers. Miss the March 1 filing deadline and you can lose a year of the benefit.

 

One of the most expensive misconceptions I hear from longtime Tampa Bay owners is this: “If I sell, I lose my low tax bill and start over.”

Not quite. You do start over on market value — but Florida lets you carry your accumulated Save Our Homes benefit to the next home. For an owner who's held a Palma Ceia or Snell Isle property for 10 or 15 years, that benefit is often worth thousands of dollars a year, every year, for as long as you own the next home. It's one of the strongest financial arguments for making the move you've been putting off — and it's routinely left on the table because the paperwork wasn't filed on time.

Here's the whole system, worked end to end.

The two benefits you're protecting: the exemption and the cap

Florida homestead comes with two distinct pieces, and portability only applies to one of them.

The homestead exemption reduces your taxable value. For 2026, the first $25,000 applies to all levies, including school taxes. A second exemption applies to the assessed value between $50,000 and $75,000 (a band that itself adjusts upward with the exemption) and covers non-school levies only — and thanks to Amendment 5, passed in November 2024, that second piece now adjusts annually for inflation. For 2026 it stands at $26,411, putting the total exemption at up to $51,411 for a fully qualified homestead.

The Save Our Homes cap is where the real money accumulates. Once your home has a homestead exemption, its assessed value can rise no more than 3% per year or the change in the Consumer Price Index, whichever is lower — regardless of what the market does. For 2026, the cap is 2.7%.

Over a decade of Tampa Bay appreciation, that cap opens a wide gap between what your home is worth (just value) and what you're taxed on (assessed value). That gap is your Save Our Homes differential — and the differential is what portability lets you take with you.

This is the number I check first with any long-tenured move-up or downsize client. I've had sellers port a substantial Save Our Homes benefit to the next home, and the difference it made to the new tax bill changed how they thought about the entire move.

You'll see all three numbers — just value, assessed value, and taxable value — on the TRIM notice your county mails each August. If you've owned a high-end South Tampa or St. Petersburg property since the mid-2010s, don't be surprised if the differential runs into six figures.

Porting the differential: the $500,000 cap and the three-year window

When you sell (or otherwise abandon) your homestead and establish a new one in Florida, you can transfer up to $500,000 of that differential to the new home. This works statewide — Hillsborough to Pinellas, Pasco to Hillsborough, Miami-Dade to Pinellas. Portability is a Florida-to-Florida benefit, not a county-specific one.

Two rules govern the transfer:

• The cap. If your differential is larger than $500,000, the excess doesn't transfer. If it's smaller, you port what you have.
• The window. You must establish the new homestead within three tax years of abandoning the old one. The clock runs on tax rolls, not calendar months: if your old home was your homestead on the January 1, 2026 roll and you sell during 2026, you generally have until January 1, 2029 to be on the roll at the new property. Sell and rent for a year or two while you shop, and the benefit survives. Wait too long, and it's gone.

Upsizing: the full differential moves

If the new home's just value is equal to or higher than the old home's, the entire differential transfers, up to the cap.

Worked example. Say you've owned a Palma Ceia home since 2012. Its 2026 just value is $1.6M, but the Save Our Homes cap has held your assessed value to $1.1M — a $500,000 differential, right at the limit. You buy on Davis Islands for $2.4M. Your new assessed value starts at $1.9M instead of $2.4M.

At combined Tampa-area millage rates — which typically land just under 2% of taxable value — a $500,000 differential is worth on the order of $9,000 to $10,000 a year. That's not a one-time credit. It's an annual reduction that then grows again under the cap at the new home.

Downsizing: a proportional share moves

If the new home's just value is lower than the old home's, you don't keep the dollar amount — you keep the percentage relationship. The formula: your new assessed value equals the new home's just value multiplied by the ratio of your old assessed value to your old just value.

Worked example. You own an Old Northeast home with a just value of $2.0M and an assessed value of $1.2M — you're being taxed on 60% of market value, with an $800,000 differential. You downsize to a $1.0M condo in downtown St. Petersburg. Your new assessed value is 60% of $1.0M, or $600,000. You've ported $400,000 of benefit — proportionally identical, even though the dollar figure shrank.

For move-down owners, that proportional treatment is the piece most people have never heard of, and it changes the math on downsizing more than most sellers expect. Before you commit in either direction, it's worth running your actual numbers — this calculation is part of what I walk sellers through when we discuss net proceeds and carrying costs on the next home. If you're timing a sale and purchase together, the sequencing questions in buying before you sell in Tampa Bay interact directly with the portability window.

The filing calendar, worked end to end

Portability isn't automatic. Here's the sequence:

1. January 1 — the status date. You must own the new property and occupy it as your permanent residence on January 1 of the year you're claiming. Close in December and move in, and you can claim for the new year. Close in January, and your first eligible tax roll is the following year.
2. File Form DR-501 — the homestead application. This establishes the exemption at the new home. Hillsborough, Pinellas, and Pasco all accept online filing through their property appraiser sites (hcpafl.org and pcpao.gov both run e-file portals).
3. File Form DR-501T at the same time. This is the Transfer of Homestead Assessment Difference — the portability application. It identifies your previous homestead so the two appraiser offices can coordinate the differential. Filing DR-501 without DR-501T is the classic mistake: you get the exemption but leave the differential behind.
4. March 1 — the deadline. Both forms are due to the property appraiser in your new county by March 1 of the claim year.
5. August — verify on the TRIM notice. When the notice arrives, confirm the ported differential actually appears in your assessed value. If the numbers look wrong, you have a limited window to act — the Value Adjustment Board petition process runs on a 25-day clock from the TRIM mailing date.

If you miss March 1, all may not be lost — Florida law gives property appraisers discretion to accept late applications up to 25 days after the TRIM notices are mailed, typically putting the true outside deadline in mid-September. But late acceptance generally requires documented extenuating circumstances, and approval isn't guaranteed. Treat March 1 as the real deadline.

A few situational notes worth knowing:

• Two owners, two directions. When co-owners split — a divorce, or two owners buying separate homes — the differential can be divided, but how it divides depends on ownership structure and requires the right designation paperwork with the property appraiser. If you're transferring property within a family instead, the deed and homestead rules around gifting a Tampa Bay home carry their own Save Our Homes consequences.
• The buyer's side of your sale. Your buyer doesn't inherit your assessed value. The property resets to just value on the January 1 after the sale — which is why a new buyer's tax bill can be dramatically higher than the seller's last bill, and why estimating taxes off the seller's TRIM notice misleads.

One more thing on the calendar: November 2026

Florida voters will decide a significant property tax amendment this November: Amendment 3, placed on the ballot by HJR 1-F during the 2026 session. It would raise the homestead exemption for non-school levies to $150,000 in 2027 and $250,000 in 2028, with inflation indexing beginning in 2029 — and it needs 60% approval to pass. One wrinkle for relocating buyers: owners who establish Florida residency on or after January 1, 2027 would start with a $50,000 non-school exemption (inflation-adjusted from 2028) for their first four years, with the full exemption beginning in year five. The amendment would also cut the assessment cap on non-homestead property from 10% to 5% — relevant if you're keeping the old home as a rental.

If it passes, the value of holding a Florida homestead grows substantially. It doesn't change anything about how portability works, and it's no reason to delay a filing — the homestead you establish now is the one any expanded exemption would attach to. It's simply worth watching if you're modeling long-term carrying costs on a purchase.

Frequently Asked Questions

Do I lose my Save Our Homes savings when I sell my Florida home?

No — not if you act within the window. You can transfer up to $500,000 of your accumulated Save Our Homes differential to a new Florida homestead, as long as you establish the new homestead within three tax years of abandoning the old one and file Form DR-501T with your new county's property appraiser by March 1.

Can I transfer my homestead benefit between Florida counties?

Yes. Portability works anywhere in Florida — moving from Hillsborough to Pinellas, or from South Florida to Tampa Bay, doesn't reduce the benefit. You file both the homestead application (DR-501) and the portability application (DR-501T) with the property appraiser in your new county, and the two counties coordinate the transfer.

How does portability work if I'm downsizing to a less expensive home?

You keep the same percentage benefit rather than the same dollar amount. Your new assessed value equals the new home's just value multiplied by the ratio of your old assessed value to old just value. If you were taxed on 60% of your old home's market value, you'll start at 60% of the new home's value.

What happens if I miss the March 1 filing deadline?

Florida property appraisers have discretion to accept late homestead and portability applications up to 25 days after TRIM notices are mailed in August — a deadline that usually lands in mid-September — but you'll generally need to document extenuating circumstances, and acceptance isn't guaranteed. If the application is denied, you can petition the county's Value Adjustment Board.

How much is the Florida homestead exemption in 2026?

Up to $51,411. The first $25,000 applies to all property tax levies, including schools. The second exemption — $26,411 in 2026 — applies to assessed value between $50,000 and $75,000 (as adjusted) and excludes school levies. It rises with inflation each year under Amendment 5, approved by voters in 2024.

 

Portability is one of the few places in a Florida transaction where a single form filed on time is worth thousands of dollars a year, indefinitely. The mechanics aren't hard — but the sequencing matters, and the deadline is unforgiving.

If you're weighing a move within Tampa Bay — upsizing, downsizing, or relocating across the bay — and want the tax math worked into your actual selling strategy and purchase numbers, a direct conversation usually clears more up than another search.
