Portability is a powerful Florida property tax benefit that allows homeowners to transfer their accumulated “Save Our Homes” (SOH) tax savings from one homesteaded property to another within the state. Introduced via constitutional amendment in 2008, it helps long-time homeowners avoid massive tax increases when they move.
If you’ve benefited from the Save Our Homes cap on your current home, portability lets you “port” that advantage to a new Florida home—potentially saving thousands of dollars annually on property taxes.
Understanding Save Our Homes (SOH) and Why Portability Matters
Florida’s Save Our Homes amendment caps the annual increase in assessed value of a homesteaded property at 3% or the Consumer Price Index (CPI), whichever is lower. Over time, this creates a significant gap between your home’s market value (what it’s worth) and its assessed value (what it’s taxed on).
Without portability, selling your long-owned home and buying a new one would reset the assessed value to the current market value, causing your property taxes to jump dramatically. Portability solves this by letting you transfer up to $500,000 of that assessment difference to your new home.
How Does Portability Work in Florida Real Estate?
When you move, you transfer the Homestead Assessment Difference—the gap between your old home’s just/market value and its capped assessed value.
The amount you can port depends on whether you’re upsizing (new home has higher market value) or downsizing (new home has lower market value):
- Upsizing: You can transfer the full SOH benefit (up to the $500,000 cap).
- Downsizing: You transfer a proportional share of the benefit based on the ratio of the new home’s market value to the old home’s market value.
Example:
- Old home: Market value $400,000, assessed value $250,000 → $150,000 SOH benefit.
- New home (upsizing): Market value $600,000 → You can port the full $150,000, reducing the new assessed value.
- New home (downsizing): Market value $300,000 → You port a percentage of the $150,000 benefit.
This lowers the taxable value of your new home and keeps future assessments capped under SOH rules.
Key Eligibility Requirements for Portability
To qualify for portability in Florida real estate:
- You must have had a homestead exemption on your previous Florida home.
- You must establish a new homestead exemption on the replacement home within three tax years (by January 1 of the third year after abandoning the old homestead).
- All owners on the old homestead must abandon it (special rules apply for divorces or partial ownership).
- You must apply for portability when filing for the new homestead exemption.
Note: The three-year window is based on tax years, not the sale date. For instance, if you abandon your homestead in 2025, you generally have until January 1, 2028, to establish the new one.

How to Apply for Portability
Portability is not automatic. You must:
- File Form DR-501 (Homestead Exemption Application).
- Submit Form DR-501T (Transfer of Homestead Assessment Difference) at the same time.
Most county property appraisers offer online applications. Apply by March 1 of the year you want the benefit. Contact your county property appraiser’s office for exact details, as they calculate and approve portability.
Many counties also provide portability estimators on their websites to preview potential savings. For example, these links will take you to the Portability Calculator sites for Palm Beach, Broward, and Miami Dade counties.
Major Benefits of Using Portability
- Significant Tax Savings: Especially valuable in high-appreciation areas like South Florida.
- Flexibility to Move: Encourages downsizing, upsizing, or relocating within Florida without tax penalties.
- Cumulative Advantage: Long-term homeowners with large SOH benefits see the biggest impact.
- Statewide Application: Works when moving between any Florida counties.
Limitations and Important Considerations
- Maximum transfer: $500,000.
- You must own and reside in the new property as your primary residence.
- Portability applies only to homestead properties.
- If your new home’s market value is much higher, the benefit is capped at $500k.
- Once used, the transferred benefit becomes part of the new home’s assessment history.
- Changes in ownership (e.g., adding/removing spouses) may require special forms like DR-501TS.
Common Questions About Florida Portability
Can I use portability if I move from a condo or townhouse? Yes, as long as it was your homesteaded primary residence.
What if I haven’t lived in my old home for a couple of years? As long as you had homestead in one of the three preceding years, you may still qualify.
Is portability available for investment or second homes? No — only primary residences with homestead exemption.
Does portability affect the $50,000+ homestead exemption? No. You still receive the standard homestead exemption on the new property in addition to the ported benefit.
Final Thoughts: Is Portability Right for You?
Portability is one of Florida’s most homeowner-friendly real estate tax provisions. It rewards long-term residency and makes moving more affordable in a state with rapidly rising property values.
Before buying or selling, consult your county property appraiser or a knowledgeable Florida real estate attorney to run the numbers. Many homeowners discover that porting their SOH benefit can offset a large portion of higher mortgage payments on a new home.
If you’re planning a move in Florida, understanding portability could save you tens of thousands over the years you own your next property. Check with your local property appraiser’s office for personalized calculations and the latest rules.
