If you’ve owned your Tampa Bay home for ten or fifteen years, there’s a good chance you’re sitting on a tax benefit that may be worth more than you realize.
Florida’s Save Our Homes cap has likely been working quietly in the background, limiting how much your assessed value can increase each year. Over time, that can create a significant gap between what your home is worth and what you’re actually taxed on.
For many long-term homeowners in Brooksville, Spring Hill, Lutz, Land O’Lakes, Tampa, Clearwater, and surrounding areas, that gap can be worth tens of thousands — sometimes even hundreds of thousands — of dollars.
The good news?
If you sell your Florida homestead and buy another Florida homestead, you may be able to take that tax savings with you.
That benefit is called Save Our Homes portability.
What Is Save Our Homes Portability?
Florida’s Save Our Homes amendment limits the annual increase in a homestead property’s assessed value to 3% or the change in the Consumer Price Index, whichever is lower.
That means your market value can rise sharply, but your assessed value — the number used to calculate your property taxes — is capped.
Over time, that creates what’s called an assessment difference.
For example:
| Item | Amount |
|---|---|
| Current market value | $580,000 |
| Assessed value | $390,000 |
| Save Our Homes benefit | $190,000 |
That $190,000 difference may be portable when you sell and buy another homesteaded property in Florida.
In simple terms, portability allows you to transfer some or all of that accumulated assessment savings to your next Florida homestead.
Why This Matters for Tampa Bay Sellers
Many homeowners hesitate to sell because they’re afraid their property taxes will reset too high on the next home.
That concern is valid.
When a new buyer purchases your home, their assessed value generally resets closer to market value. That’s why buyers relocating to Florida are often surprised by their first tax bill.
But if you already have a Florida homestead, your Save Our Homes benefit does not necessarily disappear when you sell.
You may be able to carry it with you.
That can make a major difference when deciding whether to move up, downsize, or relocate within Tampa Bay.
How Portability Works When You Buy a More Expensive Home
If your new Florida homestead has a market value equal to or higher than the home you sold, you may be able to transfer your full Save Our Homes benefit, up to the current portability cap.
Here’s a simple example:
| Item | Amount |
|---|---|
| Old home market value | $500,000 |
| Old home assessed value | $400,000 |
| Save Our Homes benefit | $100,000 |
| New home market value | $700,000 |
| New assessed value after portability | $600,000 |
In this scenario, the homeowner transfers the full $100,000 benefit to the new property.
That means the new home is not assessed at the full $700,000 market value for tax purposes. Instead, the portability benefit reduces the assessed value to $600,000.
How Portability Works When You Downsize
Portability works differently when you move into a less expensive home.
If your new home is worth less than your previous home, you usually transfer a proportional share of the benefit.
Here’s an example:
| Item | Amount |
|---|---|
| Old home market value | $500,000 |
| Old home assessed value | $400,000 |
| Save Our Homes benefit | $100,000 |
| Benefit percentage | 20% |
| New home market value | $300,000 |
| Portable benefit | $60,000 |
| New assessed value | $240,000 |
This is one of the biggest surprises for downsizing sellers.
Many assume the entire dollar amount transfers. It usually does not. Instead, the benefit is applied proportionally based on the value of the new home.
That’s why it’s important to run the numbers before making a move.
The Three Deadlines Sellers Need to Know
Portability is powerful, but it’s not automatic. Missing a deadline can cost you.
1. You Have a Three-Year Window
You must establish your new Florida homestead by January 1 of the third year after abandoning your previous homestead.
For example, if you sell your homestead in 2026, you generally have until January 1, 2029, to establish your new Florida homestead.
If you rent for too long or delay purchasing, you could lose the benefit.
2. You Must File by March 1
To receive portability, you must file for your new homestead exemption and submit the portability application by March 1 of the year you want the benefit to apply.
The key forms are:
| Form | Purpose |
|---|---|
| DR-501 | Florida homestead exemption application |
| DR-501T | Transfer of homestead assessment difference, also known as portability |
3. You Have to Specifically Request Portability
Portability does not happen automatically just because you file for homestead.
You must specifically apply for the transfer using form DR-501T.
This is where many homeowners make a costly mistake. They assume filing for homestead handles everything. It does not.
What About the November 2026 Ballot Question?
There is a proposed change on the November 2026 Florida ballot that could affect portability.
HJR 211 proposes removing the current $500,000 portability cap. If approved by Florida voters, homeowners with very large accumulated Save Our Homes benefits may be able to transfer more than the current limit.
For many Tampa Bay homeowners, the existing cap may already be enough. But for long-term owners of high-value homes, especially those who have owned their property for decades, this could become a meaningful issue.
The important point is this:
Even if the cap changes, the deadlines still matter.
You still need to establish the new homestead on time, file the correct forms, and request portability.
Where to File in Tampa Bay
Portability is a statewide Florida benefit, but you file through the property appraiser’s office in the county where your new homestead is located.
For many Tampa Bay homeowners, that may include:
| County | Property Appraiser Website |
|---|---|
| Hernando | hernandopa-fl.us |
| Pasco | pascopa.com |
| Hillsborough | hcpafl.org |
| Pinellas | pcpao.gov |
Most counties allow you to file online, by mail, or in person.
You’ll typically need the address of your previous Florida homestead, the date you abandoned it, and information about your new homestead.
What I Tell My Move-Up Sellers Before We List
When I’m working with a Tampa Bay homeowner who is thinking about selling and buying another home in Florida, the portability conversation needs to happen early.
Not after the closing.
Not after the next tax bill arrives.
Before we list.
Here are the steps I recommend:
Pull Your TRIM Notice
Your TRIM notice shows your property’s market value, assessed value, and taxable value.
The difference between market value and assessed value gives you a starting point for estimating your Save Our Homes benefit.
Know Whether You’re Upsizing or Downsizing
The math changes depending on whether your next home is more expensive or less expensive than your current home.
Upsizing may allow you to transfer the full benefit, subject to the cap.
Downsizing usually means the benefit is transferred proportionally.
Map Out Your Timeline
Selling, renting temporarily, building a home, or waiting for the right property can all affect your portability window.
You do not want to accidentally lose the benefit because the timing was not planned correctly.
Build the Filing Into Your Closing Checklist
Do not assume your title company, lender, or agent will automatically handle this for you.
You should personally confirm that your homestead exemption and portability application are filed with the correct county property appraiser by March 1.
Frequently Asked Questions
How long do I have to use Florida homestead portability?
You generally must establish your new Florida homestead by January 1 of the third year after abandoning your previous homestead. You also need to file the portability application by March 1 of the year you want the benefit to apply.
Can I use portability if I move out of Florida?
No. Portability only applies when transferring a Save Our Homes benefit from one Florida homestead to another Florida homestead.
If you move out of state, the benefit does not transfer.
What is the maximum amount I can transfer?
Currently, the maximum portability amount is $500,000 of assessment difference.
There is a proposed amendment on the November 2026 ballot that could remove that cap if approved by voters.
Does portability happen automatically?
No.
You must specifically apply for portability using form DR-501T.
Filing for homestead alone is not enough.
Can divorcing spouses split portability?
In some cases, yes. Florida law allows portability benefits to be split under certain conditions, but the process requires proper documentation. If this applies, it’s smart to speak with the property appraiser’s office or a Florida real estate attorney before filing.
Before You List, Run the Numbers
For many Tampa Bay homeowners, Save Our Homes portability can make the difference between moving comfortably and being surprised by a much higher property tax bill.
If you’re thinking about selling your home in Brooksville, Spring Hill, Lutz, Land O’Lakes, Tampa, Clearwater, or anywhere in the Greater Tampa Bay area, this is something worth looking at before you make a move.
