What Is Portability in Florida and How Does It Work?

Florida portability lets you transfer up to $500,000 of your accumulated Save Our Homes property tax savings from one Florida homestead to another when you move. The savings come from the gap between your home’s market value and its lower assessed value under the Save Our Homes cap, and portability keeps that gap working for you at your new home instead of resetting your tax bill to the new property’s full market value. You have three years from January 1 of the year you leave your old homestead to establish a new one and claim the benefit, and you have to file a separate form to do it.¹

What You’re Actually Transferring

Portability only makes sense once you understand what the Save Our Homes (SOH) cap does. Under Article VII, Section 4 of the Florida Constitution, once your home has a homestead exemption, the county property appraiser cannot raise your assessed value by more than 3% per year or the change in the Consumer Price Index, whichever is lower.¹ When the market jumps 8% or 10% a year, your assessed value creeps up slowly while the market value runs ahead. The difference between those two numbers is your SOH benefit.

Say you bought in 2018 for $250,000. By 2026, the market puts the house at $400,000, but the SOH cap has held your assessed value at $300,000. Your SOH benefit is $100,000. That is the number you port. Long-term owners in fast-appreciating areas routinely build six-figure benefits, which is why portability can save thousands of dollars a year in property taxes after a move.

How Much You Can Transfer

The math depends on whether your new home is worth more or less than the old one.

If You Upsize

When the new home’s market value equals or exceeds the market value of the home you left, you transfer the full SOH benefit, dollar for dollar, up to the $500,000 cap.² Using the numbers above, if your old home had a $400,000 market value and a $300,000 assessed value, the full $100,000 benefit moves with you. If the new home has a $500,000 market value, the appraiser subtracts your $100,000 benefit and starts your assessed value at $400,000.

If You Downsize

When the new home’s market value is lower than the old one’s, the benefit shrinks proportionally. Divide the new home’s market value by the old home’s market value, then multiply by your SOH benefit.² If your old home’s market value was $300,000 with a $100,000 SOH benefit, and the new home is worth $180,000, the calculation is $180,000 ÷ $300,000 = 60%, so $60,000 of your benefit transfers. The $500,000 cap still applies to the reduced number.

After the Transfer

Once the benefit is applied, the 3% SOH cap starts protecting your new, lower assessed value going forward.¹ Your transferred benefit becomes permanent and begins growing again as the market continues to outpace the capped assessment.

Who Qualifies

Four conditions all have to be true:

Your previous property had a homestead exemption with at least one year of SOH cap protection. Sell in the year you first got the exemption and there’s no accumulated benefit to port.
You abandoned the old homestead as your permanent residence. The property appraiser looks at objective facts (whether you moved your belongings, changed your address, stopped living there), not just stated intentions.³
You qualify for and receive the homestead exemption on the new property, meaning it is your permanent, primary residence as of January 1 of the year you apply.
You establish that new homestead within three tax years of leaving the old one.

Portability works across county lines. The old and new homes do not need to be in the same county; the new county’s property appraiser coordinates with the old county to verify your SOH benefit.⁴

One trap: renting out the old homesteaded property. If you stop using it as your permanent residence and put tenants in, you lose the homestead exemption entirely, not just portability.⁵ A temporary absence for work or health reasons will not disqualify you, as long as you genuinely intend to return and don’t rent the place out while you’re gone.³

The Three-Year Window

The statute gives you three years, counted from January 1 of the year you abandoned your old homestead, to establish a new one and file for portability.¹ The technical test is whether you held a homestead exemption on January 1 of any of the three years immediately before you establish the new homestead.

In practice: if you leave your old home in March 2024, you held homestead as of January 1, 2024. You then have until January 1, 2027, to establish the new homestead, with a March 1, 2027 filing deadline.⁵ Wait until 2028 and you are outside the window. The three preceding January 1 dates (2027, 2026, 2025) no longer include a year when you had homestead on the old property.

The benefit you transfer is calculated as of January 1 of the year you abandoned the old homestead, not the year you apply.⁵ If your old home’s market value dropped between the day you left and the day you file at the new place, that doesn’t change your calculation. The number is locked at the point of abandonment.

How to Apply

Portability requires a separate application on top of the standard homestead exemption. You file two forms with the property appraiser’s office in the county of your new home:

Form DR-501, the standard homestead exemption application.
Form DR-501T, the Transfer of Homestead Assessment Difference form.⁶

Both forms are due by March 1 of the year you want the benefit to take effect.⁶ Most property appraiser offices accept online or in-person filing, and filing both forms together is standard practice.

If You Miss March 1

Missing the deadline does not automatically kill the benefit for the year. Florida law allows a late application if you can show extenuating circumstances or that you were unable to file on time. The late application must be filed by the 25th day after the property appraiser mails the annual TRIM (Truth in Millage) notices, which typically go out in mid-August.⁷ The property appraiser decides whether your circumstances justify a late filing. If the appraiser denies it, you can petition the Value Adjustment Board.

There is also a safety net for people who received the homestead exemption on time but didn’t apply for portability specifically. If you already have homestead on the new property but didn’t file the DR-501T within the three-year window, you may still be able to apply at a later date.⁵ This is a frequently overlooked provision that catches people who didn’t realize portability was a separate filing.

Joint Owners, Divorce, and Combining Households

Portability gets complicated when more than one person has a stake in the old homestead.

Joint Owners Splitting Up

When two or more people abandon a jointly owned homestead and each establishes a separate new homestead, each person gets a share of the SOH benefit equal to the total benefit divided by the number of owners who held the exemption. If the deed lists specific ownership percentages, the split follows those percentages.¹ Married couples can designate their own split when they both abandon the property.

Watch for this trap: if only one owner moves and the other stays, the homestead has not been abandoned. The person who left cannot transfer any portability benefit, because the old homestead still exists.⁸

Two Households Becoming One

When two people who each had their own homestead buy a single new property together, they don’t get to add both SOH benefits. The reduction is limited to the larger of the two individual benefits, and the $500,000 cap still applies.¹

Divorce

Divorce follows the same rules as any joint-owner separation. If both spouses leave the marital home and each buys a new property, each takes half the SOH benefit to port separately. The Florida Department of Revenue has taken the position that these shares cannot be traded, sold, or reassigned between spouses through a settlement agreement; each person takes their statutory share. If one spouse stays in the marital home, that spouse keeps the exemption and all accumulated SOH benefit, and the departing spouse has no portability to carry.

Common Reasons Portability Is Denied

Property appraisers deny applications for specific, identifiable reasons:

No homestead on the old property on January 1 of any of the three years before you established the new homestead.⁸
The old homestead was never abandoned, because you still own and occupy it or because another co-owner remains there.
The new homestead was not established by January 1 of the application year. Closing on January 15 means missing portability for that year.
You are outside the three-year window.
The property appraiser could not identify your prior homestead or verify the SOH benefit amount, often because the old and new properties sit in different counties and records didn’t match.⁸

The “not established by January 1” issue catches the most buyers off guard. Florida determines homestead eligibility based on your status on January 1, not when you close or when you file. A short delay at closing pushes your eligibility out a full year.

How to Appeal a Denial

If the property appraiser denies your portability application, you have the right to challenge the decision at the Value Adjustment Board (VAB). The appraiser must send you a Notice of Denial (Form DR-490PORT) with the reasons by July 1.⁸

To appeal, file Form DR-486PORT (Petition to the Value Adjustment Board, Transfer of Homestead Assessment Difference) within 30 days of receiving the denial notice.⁹ The form asks for parcel identification numbers and addresses for both your old and new properties, plus a description of why you believe the denial was wrong. If you disagree with the calculated benefit amount rather than an outright denial, state the amount you believe should be transferred and explain your math.

VAB petitions carry a filing fee, typically $15, though it can vary by county. If your petition is still pending when property taxes come due, you must pay at least 75% of the ad valorem taxes plus all non-ad valorem assessments before the delinquency date, generally March 31. Failing to make that partial payment results in automatic denial of the petition.⁹

If a Hurricane Damaged or Destroyed Your Home

Florida added a special provision for homeowners whose property is significantly damaged or destroyed by a named tropical storm or hurricane. You can elect to treat the property as abandoned on the date of the storm, even if you technically held the homestead exemption through the following January 1.¹ This election is available only if you establish a new homestead by January 1 of the third year after the storm. The provision applies to damage from storms occurring on or after January 1, 2017.

Separately, if storm damage makes your home uninhabitable but you intend to repair and return, your homestead is not considered abandoned, provided you notify the property appraiser of that intent and start repairs within three years.³ That protection preserves your existing SOH benefit on the damaged property while you rebuild, which is different from porting the benefit to a new home.
