There is a number that most Florida homeowners never see on any tax form, never hear about at closing, and never think to ask their accountant about. For some people, that number is $100,000. For others, it is closer to $500,000. And because nobody mentioned it at the right time, it simply vanished the moment they signed the deed to their new home.
That number is your Save Our Homes portability benefit. And if you own a Florida home that you have lived in for more than a few years, there is a very real chance you are sitting on one right now without knowing it.
A few weeks ago, I wrote about the big property tax conversation happening in Tallahassee and what Florida’s potential elimination of property taxes would actually mean for your wallet. Today I want to zoom into something smaller in scale but just as consequential in practice, because this one does not require waiting on a legislative vote. It is already available to you. You just have to know how to use it before the clock runs out.
What Save Our Homes Actually Does
Let’s start at the beginning, because the foundation matters here.
Florida’s Save Our Homes amendment, codified under Florida Statute 193.155, limits how much your homestead property’s assessed value can increase each year. The cap is the lesser of 3% or the change in the Consumer Price Index. For 2026, that figure is effectively holding steady at around 3%.
So what does that mean in real life? It means that even when your home’s market value jumps by 15% in a hot year, your tax bill only climbs by a fraction of that. Over time, those annual savings stack up. The gap between what your home is actually worth on the open market and what the county taxes you on grows wider every year you hold the property.
That gap is your Save Our Homes benefit. It lives inside your home like equity you never had to earn. It just accumulated quietly, year after year, while the market did what Florida markets do.
The Gap Adds Up Faster Than You Think
Here is a real-world example to make this concrete.
Suppose you purchased a home in Weston in 2014 for $450,000. Your market value today might be somewhere around $850,000 or more, depending on the neighborhood. However, because of the Save Our Homes cap working on your behalf every single year, your assessed value might only be around $550,000. That means $300,000 of your home’s value is currently shielded from taxation.
At Broward County’s effective millage rate, that gap translates to roughly $4,500 to $6,000 per year in tax savings compared to what a new buyer of the same home would pay. That is not a small number… it’s actually the size of a car payment or a family vacation. That is real money.
And here is the part that most people do not realize until it is too late: when you sell that home and buy a new one, all of that protection resets to zero for you at your new address. Unless you take one specific step to prevent it.
The Concept of Portability (And Why It Exists)
Florida created portability in 2008 through Amendment 1 precisely because of this problem. The idea was straightforward: long-term homeowners should not be financially punished for moving within the state.
Under current Florida law, when you sell your homestead and purchase a new one in Florida, you can transfer up to $500,000 of your accumulated Save Our Homes benefit to the new property. This is what the state calls portability, and it is one of the most genuinely useful tax protections available to Florida homeowners.
However, it does not happen automatically. Not even close. You have to apply for it separately, on a specific form, by a specific deadline, filed with the correct county office. Miss any one of those steps and the benefit disappears as if it never existed.
The single most expensive mistake a Florida homeowner can make when moving is not knowing that portability exists until after they’ve already lost it.
How the Math Works When You Move
The calculation depends on whether you are upsizing or downsizing. Both scenarios benefit from portability, but the math works a little differently.
If you are moving to a home worth at least as much as your current one, you can transfer your full Save Our Homes benefit, up to the $500,000 cap. In our earlier example, that $300,000 gap follows you to the new property. Instead of your new home being taxed at its full $900,000 market value, it might open at an assessed value closer to $600,000. You have preserved years of accumulated protection in a single filing.
If you are downsizing, the calculation becomes proportional. The state applies the percentage of your old home’s market value that transferred to the new home, and then applies that percentage to your accumulated benefit. For example, moving from a $700,000 home down to a $490,000 home means roughly 70% of your benefit can move with you. It is not the full amount, but it is far better than starting at zero, which is exactly where you end up if you miss the filing.
The Deadlines That Kill the Benefit
This is the part I want you to read twice, because this is where the benefit actually disappears for most people.
First, you have a three-year window from January 1 of the year you last held the homestead exemption on your old property to establish a new homestead in Florida. Note that this window starts from January 1, not from your actual moving date or sale date. If you sold your home in August 2024, your three-year clock started on January 1, 2024, which means your new homestead must be in place by January 1, 2027.
Second, once you have established your new homestead, you must file Form DR-501T, the Transfer of Homestead Assessment Difference. File this by March 1 of the year following your move. You also need to file Form DR-501 for the homestead exemption itself at the same time. These are two separate applications. Filing one without the other is a common mistake. Both go to the property appraiser in the county where your new home is located, not where your old home was.
Third, your new home must be your actual primary residence as of January 1 to qualify for that tax year. Move in on February 1 and your benefits do not kick in until the following January. Timing your move matters more than most people realize when they are focused on closing dates and moving trucks.
What Happens to Homeowners Who Just Arrived in Florida
This is a question that comes up often, and it is worth addressing directly.
If you recently moved to Florida from another state, you do not have a Save Our Homes benefit yet. You cannot port something you have not built. However, you start accumulating it immediately once you establish homestead exemption on your new Florida home. Every year you stay, your protection grows. The longer you plan to be here, the more valuable this becomes.
For someone who moved to South Florida in the last year or two, the most important thing to understand is that your neighbor across the street, the one who has lived here for ten years, may be paying dramatically less in property taxes than you are on a nearly identical home. That is not an accident or an oversight. That is Save Our Homes working exactly as intended. Your job now is to start building your own benefit and protect it carefully when the time comes to move.
The good news is that Florida voters have been expanding these protections. A ballot measure in November 2026 could potentially remove the $500,000 cap on portability entirely under HJR 211, which would make the benefit even more powerful for long-term owners. However, that requires 60% voter approval and does not take effect before January 1, 2027 at the earliest. For now, the $500,000 cap remains the current law.
The Step Most Homeowners Skip
I want to be very clear about one thing, because I have seen this go wrong enough times that it bears repeating.
Portability is never automatic. Your county property appraiser does not look up your old home, calculate your benefit, and apply it to your new assessment on your behalf. That is not how it works. You have to initiate it. You have to file the right forms. And you have to do it by the March 1 deadline.
Most people who lose this benefit do not lose it because they were irresponsible or careless. They lose it because their real estate agent did not know to mention it, their title company was focused on the closing paperwork, and their accountant found out about the move in April when it was already too late.
If you are currently thinking about selling your Florida home, or if you have moved within the last year and have not yet filed, this is the thing to check immediately. The Broward County Property Appraiser’s office handles all portability applications for homes in this area, and the DR-501T form is available directly through their website. If your new home is in a different county, you file with that county’s property appraiser instead.
One More Thing Worth Knowing
Florida’s homestead exemption and the Save Our Homes cap work together as a system. The exemption reduces your taxable value by up to $50,000 at the starting point. The cap limits how fast that taxable value can grow over time. Portability lets you carry the accumulated benefit of the cap from one home to the next.
All three of these tools exist specifically to protect long-term Florida homeowners. But none of them reward passivity. They require you to file the right paperwork, meet the deadlines, and understand what you are entitled to before someone else’s negligence, or your own, costs you thousands of dollars a year.
If you want a broader view of how Florida’s property tax picture is evolving and what changes might be coming at the state level, my earlier piece on property tax elimination picks up where this one leaves off. These two articles are really one larger conversation about understanding the state you chose to live in and making sure that choice is working in your financial favor.
The Bottom Line
Florida gives long-term homeowners one of the most generous property tax protection systems in the country. The Save Our Homes cap, the homestead exemption, and portability together can save you tens of thousands of dollars over the life of a home, and potentially up to $500,000 in transferred benefit when you move.
But the system does not run on autopilot. The people who benefit most from it are the ones who understand the rules, meet the deadlines, and file the right forms at the right time. The people who lose the benefit are not less deserving. They are simply less informed.
Understanding the tax system that protects your biggest asset is not optional. It is the foundation everything else is built on.
