How Does Save Our Homes Portability Work in Florida?

Save Our Homes portability in Florida lets you carry up to $500,000 of your accumulated property tax savings from an old homestead to a new one anywhere in the state. You file Form DR-501T alongside your homestead exemption application at the new county’s property appraiser by March 1, and you must establish the new homestead within three tax years of abandoning the old one. Done right, your new home’s assessed value starts well below its market value, and your tax bill reflects that from year one.

What You’re Actually Transferring

The Save Our Homes cap limits annual increases in your homestead’s assessed value to the lower of 3% or the change in the Consumer Price Index.¹² Over years of ownership, the market value of your home usually rises faster than the cap allows the assessed value to grow. The gap between the two figures is your Save Our Homes benefit.

An example makes it concrete. If your home would sell for $400,000 today but the property appraiser has it assessed at $280,000, your SOH benefit is $120,000. Your taxes are calculated on the lower number.

Selling normally wipes that benefit out. When ownership changes, the assessed value resets to full market value for the new buyer.² Portability is the mechanism that lets you, the departing owner, take the $120,000 gap with you and apply it against the market value of your next Florida homestead.³

Two boundaries worth setting now. Portability works only between Florida homesteads; move out of state and the benefit stays behind. And portability sits on top of the standard homestead exemption, which reduces taxable value by up to $50,000. You want both, and they are separate applications.

The Three-Year Window and the January 1 Clock

You have three tax years from the date you abandoned your old homestead to establish a new one. The clock starts on January 1 of the year you left, not the date you closed the sale.³

That January 1 rule catches people. Sell in December 2026 and your last qualified homestead date is January 1, 2026, so you have until January 1, 2029 to qualify for a new homestead. That is barely over two years from the actual sale, not three.⁴ Sell in early January and you get closer to the full three years. If you plan to rent between homes, factor this in before you list.

You do not have to buy immediately. Renting for a year or two is fine as long as your new homestead is established before the window closes.

How Much of Your Benefit Transfers

The amount that moves with you depends on whether your new home costs more or less than your old one. The statute treats the two situations differently.²

Upsizing to a More Expensive Home

If your new home’s market value equals or exceeds the old home’s, your entire SOH benefit transfers, capped at $500,000. Suppose the old home had a market value of $250,000 and an assessed value of $150,000, giving you a $100,000 benefit. The new home is worth $400,000. The full $100,000 subtracts from that, and your new starting assessed value is $300,000.⁵

Downsizing to a Less Expensive Home

If the new home costs less than the old one, the benefit is prorated. The formula: divide the new home’s market value by the old home’s market value, then multiply by the old home’s assessed value. The result is your new assessed value.²

Same old home ($250,000 market, $150,000 assessed, $100,000 benefit), but the new home is worth $150,000. The math: $150,000 ÷ $250,000 × $150,000 = $90,000 assessed value. You keep $60,000 of the original $100,000 benefit.⁵ You bought a home worth 60% of the old one, so you keep 60% of the tax benefit.

Filing the Application

Portability requires Form DR-501T (Transfer of Homestead Assessment Difference), submitted with Form DR-501 (the standard homestead exemption application). Both go to the property appraiser in the county where your new home is located. Both are due by March 1 of the year you are claiming the new homestead exemption.³

The most common filing mistake is applying for the homestead exemption alone and assuming portability tags along. It does not. If you skip DR-501T, you get the basic homestead exemption and lose the SOH transfer for that year. Some counties allow both forms to be e-filed together, which reduces the chance of an oversight.

The form asks for the old and new property addresses, the date you abandoned the old homestead, and the relevant assessed values. Your old county’s property appraiser verifies the SOH figure through their own records, so you do not need an independent appraisal, but keeping your last TRIM notice from the old property helps if anything needs sorting out.

If You Miss March 1

Missing the deadline does not automatically end your chance for that year. Florida allows a late-filing route: you can submit the application up to 25 days after the property appraiser mails the annual TRIM notices, which typically go out in August. You must show extenuating circumstances that explain why you missed March 1.⁶

The property appraiser can accept or reject a late filing. “I forgot” is rarely enough. Serious illness, a natural disaster, or documented postal errors carry weight. If the appraiser rejects the late application, you can petition the Value Adjustment Board within 30 days of the denial. That petition uses Form DR-486PORT and carries a nonrefundable $15 filing fee.⁶⁷

The same 30-day VAB window applies to any straight denial of a portability application, not just late-filing rejections. Common denial grounds include missing the three-year window and gaps in the ownership chain between old and new properties. Bring documentation of dates, ownership, and prior homestead status to the hearing rather than relying on memory.

Divorce, Death, and Joint Owners

When married couples jointly own a homestead and both live there, both are treated as having received the exemption, even if only one name is on the application.² Each spouse can independently use portability if they set up separate homesteads later.

In a divorce where both spouses leave the jointly owned home, the SOH benefit can be divided between them by ownership percentage. Fifty-fifty owners each port up to half the benefit, with a $250,000 ceiling per spouse.⁸²

When a homestead owner dies, a transfer to a surviving spouse does not trigger a reassessment. The existing SOH protection continues on that home, no portability filing needed.² The same rule covers title passing by operation of law to a surviving spouse or minor child. If the surviving spouse later sells and buys elsewhere in Florida, standard portability rules then apply to the accumulated benefit.

Mistakes That Cost Real Money

File portability with your homestead application, not as an afterthought. The property appraiser will not transfer your SOH benefit unless you request it on DR-501T.
Watch the timing of your sale. A December closing shrinks your effective transfer window because the three-year clock started the previous January.
Keep your last TRIM notice from the old property. Verification is done between county appraisers, but having your own records resolves discrepancies faster.
Do not confuse portability with the homestead exemption itself. The standard exemption knocks up to $50,000 off taxable value; portability is a separate reduction on top of it. Claim both.
