Homestead Portability in Florida: Move Without a Property Tax Shock

What is homestead portability in Florida, and how much can you transfer?

Homestead portability in Florida lets you move up to $500,000 of accumulated Save Our Homes assessment savings from a home you are selling to the next Florida homestead you buy. Save Our Homes caps the annual increase in your assessed value at 3 percent or the change in the Consumer Price Index, whichever is lower, so a long-held Florida home usually carries a large gap between market value and assessed value. Portability moves that gap with you. You must establish the new homestead within three tax years of January 1 of the year you abandoned the old one, and you must file form DR-501T with your county property appraiser — it is not applied automatically.

Key takeaways

• Homestead portability lets you carry up to $500,000 of Save Our Homes assessment savings to your next Florida homestead.
• You must establish the new homestead within three tax years of abandoning the old one, and homestead portability is claimed on form DR-501T — it is never automatic.
• Upsizing transfers the full differential up to the cap; downsizing transfers a proportional share of your homestead portability benefit.

This is the single most valuable thing most long-time Florida homeowners do not know about moving. I have sat with sellers in Coral Gables and Pinecrest who assumed that moving within the state meant surrendering twenty years of tax protection and starting over. It does not, and the difference is often five figures a year.

Why the gap exists in the first place

Florida’s Save Our Homes amendment caps how fast the assessed value of a homesteaded property can rise: 3 percent a year, or the CPI change, whichever is lower. Market value is under no such cap. Over a decade of appreciation in Miami-Dade, the two diverge sharply.

The difference between market value and capped assessed value is your Save Our Homes benefit. On a home that has been homesteaded since the mid-2000s in a strong Miami-Dade neighborhood, that benefit is frequently several hundred thousand dollars of shielded value — and it resets to zero for any new owner, which is why the buyer’s tax bill after closing looks nothing like the seller’s.

How portability is calculated

The mechanics depend on whether you are moving up or down in market value.

• Upsizing. If the new home’s just value is greater than or equal to the old home’s, you transfer the full Save Our Homes differential, capped at $500,000.
• Downsizing. If the new home is worth less, you transfer a proportional share: the new home’s just value divided by the old home’s just value, multiplied by your differential — again capped at $500,000.

The transferred amount reduces the assessed value of your new homestead. The standard homestead exemption, which reduces taxable value by as much as $50,000, applies separately and on top. The Florida Department of Revenue sets out the exemptions and the portability transfer in its guide to property tax exemptions and additional benefits.

The three-year window, and how it is actually counted

This is where people lose the benefit. You must establish your new homestead within three tax years of January 1 of the year in which you abandoned the previous one. Because the count runs on tax years rather than on a rolling thirty-six months, an owner who sells late in one calendar year has meaningfully less real time than an owner who sells in January.

If you sell now and rent for two years while you look, the window is likely still open. If you rent for four, it is likely gone. Anyone planning an interim rental in Miami should map the dates before listing, not after.

Filing: the step that is easy to miss

Portability requires two filings with your county property appraiser: the standard homestead exemption application, form DR-501, and the transfer of homestead assessment difference, form DR-501T. Both are generally due by March 1 for that tax year. Neither happens automatically because you closed on a house.

Spouses who each held a homestead before marrying, or who are separating, follow specific allocation rules. Two former co-owners splitting a homestead each carry a portion of the differential. If your situation is anything other than a straightforward single-household move, confirm the treatment with the Miami-Dade County Property Appraiser before you close on the replacement.

What portability means when you are selling

For sellers, this changes the arithmetic of moving. Owners frequently stay in a home that no longer fits because they believe moving means a punitive tax reset. Once they see the portable amount quantified, the decision often flips.

It also matters for how you present your home. The tax figure on the public record is your capped number, not what a buyer will pay, and buyers who anchor on it are unpleasantly surprised in year two. Setting that expectation early prevents a renegotiation later; it belongs in the same preparation as everything else in the seller’s guide.

Portability, closing costs and carrying costs together

Portability lowers your ongoing assessment. It does nothing for your transaction costs, which are separate and immediate — the documentary stamp tax, title, prorations and the rest, all detailed in who pays closing costs in Florida.

It also does nothing for non-ad-valorem assessments. If your next home sits in a newer master-planned community, the CDD assessment arrives on the tax bill regardless of how much Save Our Homes benefit you carried over. The right comparison across two candidate homes is the full annual carrying cost, with portability applied, rather than the exemption in isolation. The broader Miami tax picture is in Miami luxury real estate taxes and homestead.

Portability would not change under the property tax measure on the November 2026 ballot. See our guide to Florida Amendment 3 for what the proposed homestead exemption increase would mean for your next home.

Frequently Asked Questions

How much homestead portability can I transfer in Florida?

Up to $500,000 of your Save Our Homes assessment differential. If you buy a home of equal or greater just value you transfer the full differential up to that cap; if you downsize you transfer a proportional share.

Do I have to sell my old home to use portability?

You have to abandon the homestead, which normally means selling, but the benefit is tied to abandoning the exemption rather than to the closing itself. If you keep the property as a rental you must still formally abandon the homestead, and the property loses the Save Our Homes cap going forward.

Is homestead portability automatic when I buy in Florida?

No. You must file form DR-501T along with your homestead exemption application with the county property appraiser, generally by March 1. Missing the filing means losing the benefit for that year.

Can I use portability moving between Florida counties?

Yes. Portability applies statewide, so a move from Broward to Miami-Dade or from Orange to Miami-Dade transfers the same way as a move within one county. It does not apply to a move out of Florida.

What happens to my property taxes if I do not qualify?

Your new home is assessed at just value with no carried-over differential, and the Save Our Homes cap begins accruing from that new baseline. For a long-held Florida home, that difference can easily be five figures in the first year.
