Florida Homestead Portability Explained: How to Take Your Save Our Homes Benefit to Your Next Home
Florida homestead portability allows an eligible homeowner to transfer all or part of the Save Our Homes assessment difference from a previous Florida homestead to a new Florida homestead.
You do not transfer your old Homestead Exemption. Instead, you apply for Homestead Exemption on the new property and separately apply to transfer your qualifying Save Our Homes assessment difference.
Under current Florida law, the maximum transferable assessment difference is $500,000, subject to eligibility and calculation rules.
For Miami-Dade homeowners who have owned a homesteaded property for many years, that distinction can matter considerably when deciding whether to move, downsize, or purchase another home in Florida.
Key Takeaways
- Florida portability transfers a qualifying Save Our Homes assessment difference, not your Homestead Exemption.
- The maximum transferable assessment difference is currently $500,000.
- You must establish a qualifying new Florida homestead within the statutory portability period.
- The three-year rule is based on Florida's January 1 assessment framework, not simply three years from your closing date.
- Moving to a more expensive home and moving to a less expensive home use different portability calculations.
- You generally apply for portability when you apply for Homestead Exemption on the new home.
- The normal filing deadline is March 1.
- You file with the property appraiser in the county where your new homestead is located.
- Portability works across Florida county lines. It is not limited to moves within Miami-Dade.
- The seller's existing tax bill does not automatically become the buyer's tax bill.

What Is Florida Homestead Portability?
Florida homestead portability is a property-tax provision that may allow an eligible homeowner to transfer some or all of the assessment difference created by the Save Our Homes limitation from one Florida homestead to another.
Florida's Save Our Homes system can create a gap between a home's just value, commonly called market value, and its lower assessed value.
For example:
|
Value on Previous Homestead |
Amount |
|
Just or market value |
$700,000 |
|
Assessed value |
$475,000 |
|
Save Our Homes assessment difference |
$225,000 |
That $225,000 difference is the important number for portability.
It is not $225,000 in cash and it is not a $225,000 tax credit. It represents an assessment difference that an eligible homeowner may be able to apply toward the assessment of a new Florida homestead.
Does Your Homestead Exemption Transfer When You Move?
No. Florida's Homestead Exemption itself does not transfer from one property to another.
The Florida Department of Revenue specifically distinguishes the two benefits: the Homestead Exemption is nontransferable, while an eligible homeowner may be able to transfer the Save Our Homes assessment difference.
When you establish a new permanent residence, you apply for a new Homestead Exemption on that property.
Portability is a separate but related application involving your previous assessment history.
A simple way to remember the distinction is:
|
Benefit |
What Happens When You Move? |
|
Homestead Exemption |
You apply again on the new qualifying homestead |
|
Save Our Homes assessment difference |
An eligible amount may be transferred through portability |
|
Seller's Homestead/SOH benefit |
Does not simply pass to the buyer |
If you need a refresher on the exemption itself, see my guide to Miami-Dade Homestead Exemption.
What Does Portability Actually Transfer?
Portability transfers an eligible portion of the difference between the previous homestead's just value and assessed value.
Florida Statute 193.155 calls this the assessment limitation difference.
Suppose your previous home has:
- Just value: $650,000
- Assessed value: $400,000
- Assessment difference: $250,000
Your potential portability benefit begins with that $250,000 difference.
Whether the entire $250,000 transfers depends on the new property's value, the ownership circumstances, and other statutory requirements.
The maximum transferred assessment difference is currently $500,000.
This is why portability should not be described as simply “taking your old tax bill with you.”
You are transferring an assessment benefit, not a tax rate, tax bill, exemption amount, purchase price, or dollar-for-dollar tax savings.
Who May Qualify for Florida Homestead Portability?
Under current Florida law, a person establishing a new homestead can qualify for portability when that person received a Florida Homestead Exemption as of January 1 of one of the three immediately preceding years, provided the other statutory requirements are met.
In practical terms, the typical homeowner must:
- Have had a qualifying Homestead Exemption on a previous Florida residence.
- Abandon that previous homestead.
- Own and establish a new qualifying Florida homestead within the portability period.
- Apply for Homestead Exemption on the new property.
- Apply to transfer the eligible assessment difference.
Portability applies to moves within Florida. Moving from Miami-Dade to Broward, Palm Beach, Monroe, Orange, Hillsborough, or another Florida county does not automatically eliminate eligibility.
Moving outside Florida is different because the new property would not be a Florida homestead for purposes of Florida's portability system.
Ownership situations involving spouses, former spouses, multiple owners, different prior homesteads, or divided ownership interests can involve additional rules under Florida Statute 193.155.
For a complicated ownership situation, the safest course is to ask the relevant county property appraiser to review the facts before relying on an estimated portability amount.
How Much Save Our Homes Benefit Can You Port?
Florida currently limits the transferable assessment difference to $500,000.
But $500,000 is a maximum, not an automatic benefit.
Your actual portability amount depends primarily on:
- your previous property's just value,
- its assessed value,
- the resulting Save Our Homes assessment difference,
- the new property's just value,
- whether you are effectively upsizing or downsizing, and
- applicable ownership rules.
How Does Portability Work When You Buy a More Expensive Home?
When the new homestead's just value is greater than or equal to the prior homestead's just value, Florida law generally subtracts the qualifying assessment difference from the new home's just value, subject to the $500,000 maximum.
The Miami-Dade Property Appraiser provides this straightforward example:
Example: Moving Up
Previous homestead
- Just value: $250,000
- Assessed value: $150,000
- Save Our Homes assessment difference: $100,000
New homestead
- Just value: $400,000
- Portability benefit: $100,000
- Initial assessed value after portability: $300,000
The basic calculation is:
$400,000 − $100,000 = $300,000 assessed value
This example assumes the full $100,000 qualifies for transfer.
Miami-Dade uses essentially this example in its official portability guidance.
Remember that this is an assessment calculation. It does not mean the homeowner receives a $100,000 exemption from the tax bill itself.
How Does Portability Work When You Buy a Less Expensive Home?
Downsizing works differently.
If the new homestead's just value is less than the previous homestead's just value, Florida generally preserves the proportional relationship between assessed value and just value rather than transferring the entire dollar difference.
Miami-Dade provides an excellent example.
Example: Downsizing
Previous homestead
- Just value: $250,000
- Assessed value: $150,000
- Assessment difference: $100,000
The previous assessed value represents:
$150,000 ÷ $250,000 = 60%
Now assume the new home has a just value of $150,000.
The calculation becomes:
$150,000 × 60% = $90,000 assessed value
The resulting assessment difference on the new home is:
$150,000 − $90,000 = $60,000
So although the previous home had a $100,000 assessment difference, the downsized property's calculated portability benefit becomes $60,000 in this example.
This calculation appears in the Miami-Dade Property Appraiser's official portability guidance.
Why is the benefit smaller when downsizing?
Because Florida's formula generally carries over the assessment ratio when the new homestead is worth less than the prior homestead.
That distinction is particularly important for longtime Miami-Dade homeowners considering selling a higher-value home and purchasing a smaller condominium, townhouse, or single-family home.
Do not assume that a $300,000 Save Our Homes assessment difference on your current residence automatically means a $300,000 reduction in assessed value on a substantially less expensive replacement home.
What Is the Three-Year Portability Rule?
The portability period is one of the most important rules to understand correctly.
The Florida Department of Revenue states that an eligible homeowner must establish the new homestead within three years of January 1 of the year the previous homestead was abandoned. It specifically warns that the rule is not simply three years from the sale date.
Florida Statute 193.155 expresses the rule by requiring the person establishing the new homestead to have received a Homestead Exemption as of January 1 of one of the three immediately preceding years.
Example
Suppose you had Homestead Exemption on your Miami-Dade residence on January 1, 2026 and sold or abandoned that homestead later in 2026.
A new homestead established as of January 1, 2029 can potentially remain within the statutory three-year framework because January 1, 2026 is one of the three immediately preceding January 1 dates.
The important lesson is this:
Do not calculate portability eligibility by simply adding three years to your closing date.
Florida property-tax rules revolve heavily around January 1 assessment dates.
If you are near the end of the portability period, verify the exact dates with the property appraiser before making assumptions.
What Is the Filing Deadline for Portability?
The normal filing deadline for Homestead Exemption and the Transfer of Homestead Assessment Difference is March 1.
Florida's portability application is Form DR-501T, Transfer of Homestead Assessment Difference, which is filed with the Homestead Exemption application.
For a new Miami-Dade homestead, the Miami-Dade Property Appraiser provides an online application system that includes Homestead Exemption and portability.
What if you miss March 1?
Do not assume that missing March 1 automatically gives you an ordinary extension.
Florida Statute 193.155 provides a limited procedure for qualified applicants who miss the deadline. A taxpayer may seek relief through the Value Adjustment Board within the statutory period following the mailing of the property-tax notice, and the law requires qualifying circumstances for late relief.
Miami-Dade also provides a late-file process involving extenuating circumstances, with supporting documentation due within the applicable period following mailing of the TRIM Notice.
Florida law also allows certain otherwise-qualified taxpayers to apply in a subsequent year, but the portability reduction applies when first approved and prior-year taxes generally are not refunded under that provision.
Practical advice: treat March 1 as the deadline and file on time whenever possible.
Where Do You File for Portability?
You file with the property appraiser for the county where your new homestead is located.
That is true even when your previous homestead was located somewhere else in Florida.
For example:
- Previous homestead: Miami-Dade County
- New homestead: Palm Beach County
You apply with the Palm Beach County Property Appraiser because that is where the new homestead is located.
The new county then communicates with the property appraiser in the previous county.
Under Florida Statute 193.155, when the prior homestead is in another county, the new county's property appraiser transmits the necessary information to the prior county. The prior county supplies the assessment information needed to determine the transferable difference, and the new county property appraiser calculates and applies the transfer.
That process is one reason you generally do not need to personally recreate your entire assessment history.
You should still provide accurate information about the prior homestead when applying.
What Happens If You Move Within Miami-Dade County?
The same statewide Florida portability rules apply.
If you sell a homesteaded home in Kendall and establish a new qualifying homestead in Pinecrest, Coral Gables, Miami Lakes, Homestead, or elsewhere in Miami-Dade, you are still dealing with the Miami-Dade Property Appraiser.
You apply for the new Homestead Exemption and portability on the new property.
Because both properties are in the same county, Miami-Dade already maintains the relevant assessment records.
The underlying benefit, however, is a Florida statewide property-tax provision, not a special Miami-Dade program.
What Happens If You Move to Another Florida County?
Portability can cross county lines.
For example, a qualifying Miami-Dade homeowner who establishes a new Florida homestead in Broward County may apply to transfer an eligible Save Our Homes assessment difference.
The homeowner files in the county of the new residence.
The new county requests and receives the necessary assessment information from the county of the previous homestead. Florida law directs the new county property appraiser to calculate the transferable amount based on that information.
Your accumulated benefit therefore does not necessarily disappear simply because you leave Miami-Dade.
It does, however, remain subject to statewide eligibility, timing, calculation, and ownership rules.
Does Portability Mean You Keep Your Old Property-Tax Bill?
No. Portability does not transfer your old property-tax bill to your new home.
This misconception can cause major budgeting errors.
Your new property may have:
- a different just value,
- a different assessed value,
- different taxing jurisdictions,
- different millage rates,
- different exemptions,
- different non-ad valorem assessments, and
- a different portability calculation.
Portability affects the assessed value of the new homestead. It does not copy the old home's entire tax calculation.
A homeowner who paid $5,000 per year on the previous property should not assume the new home will also generate a $5,000 tax bill.
Why Should Buyers Not Rely on the Seller's Property-Tax Bill?
The same principle applies when evaluating a home you are buying.
The seller's current property taxes may reflect years, or even decades, of accumulated Save Our Homes protection.
When a normal change of ownership occurs, Florida law generally requires reassessment at just value on the following January 1, subject to applicable exceptions and any portability benefit belonging to the new owner.
The Miami-Dade Property Appraiser specifically cautions that current or previous taxes may not accurately forecast future property taxes. If a property was receiving a Save Our Homes cap, that cap may be removed after the property is sold.
That is why I strongly recommend understanding why property taxes can go up after buying a Miami home before using the seller's current bill to estimate your future housing costs.
Your own portability benefit may help reduce the new assessment, but the seller's Save Our Homes history generally does not become yours.
How Can Portability Affect a Decision to Move?
Portability can change the financial picture for homeowners who have accumulated a substantial Save Our Homes assessment difference.
Consider a homeowner who has lived in the same Miami-Dade property for many years.
The home might have:
- Just value: $900,000
- Assessed value: $520,000
- Assessment difference: $380,000
Without considering portability, the homeowner might compare a potential replacement property's current seller tax bill with the taxes on the existing residence and conclude that moving will create an enormous property-tax increase.
That comparison may be incomplete.
If the homeowner qualifies to port a meaningful portion of the $380,000 assessment difference, the assessed value of the replacement homestead could be lower than a simple purchase-price comparison suggests.
The reverse is also important.
A homeowner should not assume portability eliminates all tax consequences of moving.
The actual result depends on the new property's value, applicable tax rates, exemptions, non-ad valorem assessments, and the portability calculation.
Portability can be especially relevant when:
- moving from a longtime homestead to a more expensive home,
- downsizing after retirement,
- relocating from Miami-Dade to another Florida county,
- selling and renting temporarily before buying another Florida home,
- evaluating whether a move still makes financial sense after considering future taxes.
Portability is therefore one piece of the housing-cost calculation, not the entire calculation.
Where Can You See the Portability Benefit After It Is Applied?
Your annual Notice of Proposed Property Taxes, commonly called the TRIM Notice, provides important information about the assessment of your property.
That notice helps you review your:
- just or market value,
- assessed value,
- assessment reductions,
- exemptions,
- taxable value, and
- proposed taxes.
If you recently transferred a Save Our Homes assessment difference, reviewing these numbers can help you confirm whether the assessment appears consistent with what you expected.
My guide to the Miami-Dade TRIM Notice explains how to read that notice and what homeowners should check.
If the portability application is denied, or if necessary prior-county information has not been obtained, Florida law also provides procedures involving the property appraiser and Value Adjustment Board.
Common Misunderstandings About Florida Portability
Myth: My Homestead Exemption moves to my new house.
Reality: You apply for Homestead Exemption on the new home. Portability concerns the Save Our Homes assessment difference, not the exemption itself.
Myth: I get to transfer my old property-tax bill.
Reality: Portability affects assessed value. Your new home's final taxes depend on additional factors.
Myth: Everyone gets $500,000 of portability.
Reality: $500,000 is the statutory maximum assessment difference that can be transferred. Your actual qualifying amount may be much lower.
Myth: If I downsize, my entire assessment difference automatically transfers.
Myth: I have exactly three years after my closing date.
Myth: Portability only works within the same county.
Reality: A qualifying Save Our Homes assessment difference can be transferred between Florida counties. The new county coordinates with the prior county.
Bottom Line
Selling your Miami-Dade homestead does not necessarily mean losing the entire Save Our Homes benefit you accumulated while living there.
Florida portability may allow you to carry all or part of your eligible assessment difference to your next Florida homestead, up to the current $500,000 maximum.
But portability does not transfer your Homestead Exemption, your tax rate, or your old tax bill.
The amount can also change when you downsize, and the January 1 timing rules and March 1 filing deadline matter.
If you are considering selling a longtime Miami-Dade homestead and buying another Florida home, portability deserves to be part of the conversation before you estimate your future property taxes.

Frequently Asked Questions
What is Florida homestead portability?
Florida homestead portability allows an eligible homeowner to transfer all or part of the Save Our Homes assessment difference from a previous Florida homestead to a new Florida homestead. The benefit reduces the new property's assessed value rather than transferring the previous property's tax bill.
How much Save Our Homes benefit can I transfer in Florida?
The current maximum transferable Save Our Homes assessment difference is $500,000. The actual amount may be lower depending on the previous assessment difference, the value of the new home, ownership circumstances, and Florida's portability calculation.
Can I transfer my Homestead Exemption to another Florida home?
No. Florida's Homestead Exemption itself is not transferable. You apply for Homestead Exemption on your new qualifying residence and separately apply to transfer your eligible Save Our Homes assessment difference.
How long do I have to use Florida portability?
Under current law, the person establishing the new homestead must have received Homestead Exemption as of January 1 of one of the three immediately preceding years. The Florida Department of Revenue explains this as establishing the new homestead within three years of January 1 of the year the prior homestead was abandoned. It is not simply three years from the sale date.
What is the deadline to apply for portability in Florida?
The normal deadline is March 1. Form DR-501T, Transfer of Homestead Assessment Difference, is generally filed with the Homestead Exemption application for the new home. Limited late-filing procedures may exist, but homeowners should not rely on them as routine extensions.
Can I transfer my Save Our Homes benefit from Miami-Dade to another Florida county?
Yes, if you otherwise qualify. You file with the property appraiser in the county of your new homestead. That office obtains the required information from the property appraiser in the county of your previous homestead.
What happens to portability if I buy a less expensive home?
When the new homestead has a lower just value than the prior homestead, Florida generally applies a proportional calculation. This means the dollar amount transferred may be smaller than the full assessment difference you accumulated on the previous home.
Does the seller's Save Our Homes benefit become mine when I buy the house?
Generally, no. In a normal sale, the seller's accumulated Save Our Homes assessment history does not simply transfer to the buyer. The buyer's new assessment and any portability benefit are based on the buyer's own circumstances.
