Homestead portability in Tampa Bay lets you carry your property tax savings from your old home to your new one. You can transfer up to $500,000 in saved value when you move within Florida. Many sellers forget this benefit, and it can cost them thousands of dollars each year.
I have helped many families move within Hillsborough and Pinellas County. When they use portability, they often keep a big part of their tax savings. That one step can change what your new home costs you every single year.
This guide explains how portability works. It covers the $500,000 cap, the three tax year window, and the March 1 deadline. My goal is to help you feel prepared and supported before you move.
What Is Homestead Portability in Tampa Bay?
Homestead portability is a Florida rule that lets you move your Save Our Homes savings to a new home. It applies when you sell one homesteaded property and buy another one in Florida.
Florida caps how much your assessed value can rise each year on a homesteaded home. This is called the Save Our Homes benefit. Over time, your assessed value grows slower than your market value. The gap between the two is your savings.
When you move, portability lets you take that gap with you. Without it, you would start over at full market value on the new home. That would mean a much higher tax bill.
The Difference Between Market Value and Assessed Value
Your market value is what your home would sell for. Your assessed value is the number the county uses to figure your taxes. Save Our Homes keeps your assessed value lower than your market value.
Here is a simple example:
- Market value of your current home: $500,000
- Assessed value after Save Our Homes: $350,000
- Your portability savings: $150,000
That $150,000 gap is what you can move to your next home.
How Much Can You Transfer? The $500,000 Cap
You can transfer up to $500,000 in Save Our Homes savings to your new home. This is the most Florida allows, no matter how large your gap is.
The transfer works in two ways. It depends on whether you buy a more expensive home or a less expensive one.
Upsizing to a More Expensive Home
If your new home costs more than your old one, you move the full dollar amount of your savings. You simply subtract your gap from the new home's market value.
- Old home market value: $500,000
- Old home assessed value: $350,000
- Savings gap: $150,000
- New home market value: $600,000
- New assessed value: $600,000 minus $150,000 = $450,000
Downsizing to a Less Expensive Home
If your new home costs less, you transfer a percentage of your savings instead. You divide your gap by your old market value. Then you apply that percentage to the new home.
- Savings percentage: $150,000 divided by $500,000 = 30%
- New home market value: $400,000
- Transferred savings: 30% of $400,000 = $120,000
- New assessed value: $400,000 minus $120,000 = $280,000
What Is the Three Tax Year Window?
You have three tax years to move your portability benefit to a new home. The clock starts on January 1 of the year after you leave your old homestead.
This part confuses many sellers. The window is measured in tax years, not a simple 36 months. A tax year in Florida runs from January 1 to December 31.
Here is how the timing works:
- You sell or leave your homestead in a given year.
- The count begins on January 1 of the next year.
- You must have a new homestead within three tax years.
Because of this rule, timing matters. If you wait too long between selling and buying, you can lose the benefit. I always talk through this window with clients so no one runs out of time.
A Timing Example for Hillsborough and Pinellas Sellers
Say you sell your St. Petersburg home in 2026. Your three tax year window would generally run through the end of 2028. If you buy a new Tampa Bay home in that window and file on time, you keep your savings.
The March 1 Filing Deadline Sellers Miss
You must file for portability by March 1 of the year you claim it on your new home. This deadline is the one most sellers forget.
Portability is not automatic. You must fill out a form and turn it in to your county property appraiser. In Tampa Bay, that means the Hillsborough County Property Appraiser or the Pinellas County Property Appraiser.
You will need two forms:
- Form DR-501: the homestead exemption application for your new home.
- Form DR-501T: the transfer of homestead assessment difference, which is the portability form.
If you miss March 1, you may have to wait a full year to claim the benefit. That can mean a higher tax bill for that year.
Portability in Hillsborough vs. Pinellas County
Portability works the same way in both counties, but you file with the county where your new home sits. The rule is a state law, so the cap and window do not change.
Detail | Hillsborough County | Pinellas County |
|---|---|---|
Where to file | Hillsborough Property Appraiser | Pinellas Property Appraiser |
Filing deadline | March 1 | March 1 |
Transfer cap | $500,000 | $500,000 |
Time window | 3 tax years | 3 tax years |
If you move from Tampa to St. Petersburg, you file in Pinellas. If you move from St. Pete to Odessa, you file in Hillsborough. The forms are the same in both places.
Steps to Claim Your Homestead Portability
Follow these steps to protect your tax savings when you move. Doing them in order keeps you on track.
- Confirm your current home has a homestead exemption.
- Ask your county appraiser for your assessed value and market value.
- Subtract the two numbers to find your savings gap.
- Buy and move into your new Florida home within three tax years.
- File Form DR-501 and Form DR-501T by March 1.
- Keep copies of everything for your records.
I am always glad to help clients gather these numbers before a move. A little planning early can save a lot of money later.
