If you are moving your Florida homestead, the money at stake is not the exemption itself — it is the Save Our Homes assessed-value savings you may be able to carry forward. For buyers and sellers in Miami-Dade, Broward, and Palm Beach, portability can be the difference between keeping a lower taxable value on your next home or resetting to a much higher one.
Bottom line: Portability does not transfer your homestead exemption like a moving sticker. It transfers the Save Our Homes differential — the gap between just value and assessed value — so your next homestead may start with a lower taxable value.
In Florida, the homestead exemption reduces taxable value, but portability of homestead exemption Florida is about preserving the assessment savings created by the Save Our Homes cap. That cap limits how much a homestead’s assessed value can rise each year, generally to 3% or the change in CPI, whichever is lower. Over time, the gap between market value and assessed value can become substantial.
That gap is called the Save Our Homes differential. When you move from one Florida homestead to another, you may be able to transfer some or all of that differential to the new property. The new county property appraiser then uses that transferred benefit to lower the assessed value of your replacement homestead.
| Term | Meaning | Why it matters |
|---|---|---|
| Just value | Market value used for assessment purposes | This is the starting point for the new home |
| Assessed value | The value after assessment caps and allowable adjustments | This is the value that portability helps preserve |
| Save Our Homes differential | The difference between just value and assessed value on the prior homestead | This is the portable benefit |
Important distinction: you are not transferring a tax bill. You are transferring the benefit created by the assessment cap. That is why portability can matter even when your new home is in a different South Florida county.
The calculation starts with your old homestead’s Save Our Homes differential. The county appraiser then determines how much of that differential can be transferred to the new homestead based on the new property’s just value and whether the new home is higher or lower in value than the old one.
| Move type | How the calculation works | Practical result |
|---|---|---|
| Upsizing | Transfer the prior Save Our Homes differential, capped at $500,000 | Your new assessed value may stay significantly below market value |
| Downsizing | The transferable benefit is generally reduced proportionally when the new homestead has a lower just value | You may not carry over the full differential, but you can still preserve part of it |
| Different county | The statewide portability rule still applies | Moving across county lines does not cancel portability |
Use this structure if you are moving to a larger or more expensive home in Miami-Dade, Broward, or Palm Beach:
In an upsizing move, the key tax-saving move is simple: the bigger the old differential, the more valuable portability becomes. If your new home is in a higher-priced South Florida neighborhood, preserving that differential can keep the taxable value much lower than a fresh assessment would allow.
Downsizing works differently because the new home has a lower just value. In that case, the portable benefit is generally reduced proportionally.
This is why downsizing does not mean you lose the benefit completely. You may still preserve part of the savings you built up on the prior homestead. For a condo-to-condo move, or a single-family home downsize in Palm Beach County, the county calculation can still meaningfully reduce the new assessed value.
Takeaway: If your old home had a large Save Our Homes gap, portability can materially reduce the assessed value of your next homestead — even when you move to a different county.
To compare current neighborhood price levels before you file, review South Florida neighborhood data at brokerone.io/neighborhoods. That helps you estimate whether you are moving up, moving down, or staying roughly flat in just value before the county applies the portability formula.
| Form or document | Purpose | When you need it |
|---|---|---|
| DR-501T | Requests portability of the Save Our Homes benefit | When filing for the new homestead exemption |
| New homestead exemption application | Establishes the new property as your primary residence | Required for portability to matter |
| Prior homestead information | Allows the appraiser to verify the old differential | Used during the portability review |
Yes. Florida portability is statewide. You can move from Miami-Dade to Broward, from Broward to Palm Beach, or anywhere else in Florida, and the portability rule still applies as long as the new property qualifies as your homestead and you meet the timing requirement.
| County | Can you port there? | Who handles the filing? | What South Florida buyers should remember |
|---|---|---|---|
| Miami-Dade | Yes | The county property appraiser for the new homestead | Use the new home’s just value in the portability calculation |
| Broward | Yes | The county property appraiser for the new homestead | Cross-county moves do not block the benefit |
| Palm Beach | Yes | The county property appraiser for the new homestead | File on time and keep the old homestead records |
If you are comparing neighborhoods across counties, review Broker One neighborhood data before you lock in the new homestead. The portability formula is statewide, but the market value of the next home will decide how much of your saved assessed value actually helps you.
Bottom line: Different county is not a problem. Different residency status is the problem. The new home must be your Florida homestead.
Florida portability is based on the Save Our Homes differential, which is the difference between the old homestead’s just value and assessed value. If the new homestead has a higher just value, you can generally transfer the prior differential up to $500,000. If the new homestead has a lower just value, the portable amount is generally reduced proportionally. The county property appraiser performs the final calculation.
There is no stated lifetime limit on how many times you can use portability. You can use it again each time you move from one qualifying Florida homestead to another, as long as you meet the homestead and timing rules each time.
You can transfer the benefit created by the homestead assessment cap, not the exemption itself. In practical terms, portability lets you carry over the Save Our Homes savings to a new Florida homestead. The new property still needs its own homestead exemption filing.
Do not wait until the last minute. The safest approach is to apply for portability when you file for the new homestead exemption. If the old homestead is already sold, that does not automatically disqualify you. What matters is whether you are still within the required 2-tax-year window and whether the new property qualifies as your homestead.
Yes. Portability works across Florida county lines. A move from Miami-Dade to Broward, or from Broward to Palm Beach, can still qualify if the new property is your Florida homestead and the paperwork is filed correctly.
Not directly, unless the property becomes the owner’s Florida homestead. Portability is a homestead benefit, so it does not apply to a rental or a standard investment property that is not your primary residence.
