What Orlando Homeowners Lose If They Don't Transfer Their Save Our Homes Portability

If you bought a home in Orange County in 2026, a single form filed by March 1, 2027 could cut your taxable value by six figures. Here’s the math, the paperwork, and what your Realtor probably didn’t tell you.
Imagine you bought a home in Dr. Phillips in 2010 for $350,000. Fifteen-plus years later, that house has a just value approaching $700,000. Thanks to Florida’s Save Our Homes cap, your assessed value has crept up only a few percent each year — the gap between those two numbers is somewhere around $200,000 to $250,000. That gap is years of tax protection that kept your bill manageable while the market ran away from you.
Now you’ve sold that house and closed on a $480,000 home in Windermere in 2026. You also just walked away from $200,000-plus in accumulated tax protection that is either going to follow you to your new address or disappear forever. Whether it transfers depends entirely on one two-page form filed at one specific office by March 1, 2027.
This is not a footnote in your closing packet. It’s the largest single tax decision you’ll make in connection with your move, and the overwhelming majority of Orange County homeowners make it without knowing it exists.
What the Save Our Homes Cap Actually Is
Florida’s Save Our Homes law — codified at Florida Statute § 193.155 — caps annual increases in a homesteaded property’s assessed value at 3 percent or the Consumer Price Index, whichever is lower. The cap applies only to properties with an active homestead exemption, meaning the home must be your primary residence and you must have filed for the exemption with the county property appraiser.
The result is a growing gap between what the market says your home is worth and what the county is allowed to tax you on. That gap is the Save Our Homes differential.
Orlando’s housing market ran particularly hard between 2012 and 2024. Median prices in Winter Park, College Park, and the Dr. Phillips corridor have more than doubled since 2012. A homeowner who bought in Dr. Phillips at $350,000 and now sees a just value approaching $700,000 has a differential well above $200,000 — potentially worth $4,000 or more per year in tax savings. That savings simply vanishes if portability is abandoned.
The homestead exemption itself — the base $50,000 deduction every Florida homeowner knows to file — is a separate benefit from portability and widely understood. Portability is the piece that slips through the cracks. (If you haven’t yet filed for a homestead exemption on your new Orange County home, that filing also carries a March 1 deadline and requires its own form. CityDesk has previously covered that process in detail.)
How Portability Actually Works
Portability is Florida’s mechanism for letting a homeowner take their accumulated Save Our Homes differential to a new homesteaded property. The differential doesn’t stay with the old house. It follows you — but only if you claim it, and only within limits set by statute.
The statutory cap on a portable SOH differential is $500,000 under current law. Advocacy efforts to raise or eliminate that cap have been active in recent legislative sessions, so confirm the current figure with the Florida Department of Revenue or OCPA before doing any serious planning around it. For most Orange County homeowners, that ceiling won’t matter. Their differential falls well below it.
If you’re upsizing or buying at equal value: You can transfer your full SOH differential up to the statutory cap. Here’s the worked example this piece has been building toward.
Prior home: just value $450,000, assessed value $250,000, SOH differential $200,000. New home in Orange County: just value $480,000.
Without portability, your new taxable value is $480,000 minus the $50,000 homestead exemption — that’s $430,000. With portability: $480,000 (new just value) minus $200,000 (transferred SOH differential) minus $50,000 (homestead exemption) equals $230,000 taxable value. A $200,000 reduction in assessed value on day one. That’s not a rounding error.
To convert that into actual dollars, you need your specific millage rate. Orange County’s total effective rate — combining countywide general, library, fire/rescue, and other levies — runs around 20 mills for unincorporated areas, though it varies by taxing district, and incorporated cities like Windermere and Winter Park add their own municipal millage on top. Check your TRIM notice from OCPA for the exact rate on your parcel. At 20 mills ($20 per $1,000 of taxable value), a $200,000 reduction in assessed value saves roughly $4,000 in year one. Every $100,000 of reduced assessed value is worth around $2,000 annually.
If you’re downsizing: Florida law prorates the transferable differential. The formula is (New Just Value ÷ Prior Just Value) × Prior SOH Differential = Transferable Amount. Moving from a home with a just value of $450,000 and a $200,000 SOH differential to a home with a just value of $320,000, you’d transfer roughly $142,000 — not the full amount, but not nothing either. Even a significant downsize preserves a meaningful chunk of your accumulated protection.
One thing worth emphasizing: portability reduces your assessed value from the first day your new homestead is in effect. There’s nothing to file annually after the initial form. It simply becomes part of your property record.
The DR-501T Form and What You Need
The form is called the DR-501T, “Transfer of Homestead Assessment Difference.” Download it from the Florida Department of Revenue’s website or pick it up directly from the Orange County Property Appraiser’s office.
Most important: you file DR-501T with your new county’s property appraiser, not the county you moved away from. If you sold in Orange County and bought in Orange County, you file with OCPA. If you moved to Osceola or Seminole, you file with that county’s appraiser.
Orange County Property Appraiser — main office: 200 S. Orange Ave., Suite 1700, Orlando, FL 32801. Phone: 407-836-5044. Website: ocpafl.org. OCPA has expanded its digital services in recent years; check ocpafl.org to confirm whether DR-501T can be submitted through the online portal before making the trip downtown.
The deadline is unambiguous: March 1 of the year following the year you established your new homestead. Closed in 2026, established homestead January 1, 2027. Deadline: March 1, 2027. There is no grace period and no late-filing provision for portability under current Florida statute.
What you need to file:
- Completed DR-501T form
- Your prior year TRIM notice from your previous county, which shows both the just value and the assessed value of your prior home — this is what establishes your SOH differential on paper
- If you’ve lost your TRIM notice, call OCPA at 407-836-5044 first; they can often coordinate with the prior county’s appraiser to pull the record, but don’t assume that happens automatically
Buyers who closed on builder homes in Lake Nona, Horizon West, or anywhere along the Dr. Phillips new-construction corridors are at particular risk here. The builder’s closing coordinator or the title company handles the deed, title insurance, and closing disclosure. They do not file DR-501T. They’re not required to. Many new-construction buyers assume that because the closing process was professionally managed, the tax filings were handled too. They’re wrong, and typically nobody corrects that assumption until after the March 1 deadline has passed and the portability benefit is gone. This gap appears consistently in our legal & finance coverage of Florida homeowner tax obligations.
The Three-Year Window and When It Closes
Florida Statute § 193.155(8)(f) contains the rule that catches homeowners most off guard. Portability is only available if the new homestead is established no later than January 1 of the third tax year after the prior homestead was abandoned. Sold your home in 2024: you must establish a new homestead by January 1, 2027. Sold in 2025: by January 1, 2028. Hard cutoffs, no exceptions.
The window’s starting point is where this gets genuinely tricky. The clock doesn’t necessarily start on the day you close on the sale. It starts when the prior homestead exemption is removed — which may be the year you stopped using the property as your primary residence, not the year you sold it.
This matters specifically for homeowners who rented out their former primary residence before eventually selling — a common move in a market where Orlando rents stayed elevated. If you converted your Dr. Phillips home to a rental in 2021 and sold it in 2023, the county likely removed your homestead exemption in 2021. Your portability clock may have started then. If so, your window to establish a new homestead closed January 1, 2024, regardless of when the sale recorded. If you’re in that situation and thought you still had time, you need to call OCPA this week.
Confirm the specific trigger date that applies to your situation directly with OCPA at 407-836-5044. This is the question where a five-minute phone call can save or cost you thousands of dollars a year.
Cross-County Portability
Most Orlando-area homeowners relocating within the metro assume portability only works within the same county. It doesn’t. Florida Statute § 193.155(8) makes portability available statewide.
Moving from Orange County to Osceola County — Kissimmee, St. Cloud, Celebration, Harmony — means filing DR-501T with the Osceola County Property Appraiser at 407-742-5000. Relocating to Seminole County (Oviedo, Lake Mary, Longwood, Sanford, Winter Springs), file with the Seminole County Property Appraiser. Confirm current contact details directly with each office before filing.
When you file DR-501T with your new county’s appraiser, they’ll request your prior property’s assessment records from OCPA. You’re not generally required to separately contact your old county’s appraiser. That said, confirm this directly with your new county’s office at the time of filing — inter-office coordination can lag, and any gap that leaves your file incomplete by March 1 is your problem to fix, not theirs.
If you moved from Orange County to Seminole or Osceola in 2024 or 2025 and never filed DR-501T, your window may still be open. Call your new county’s property appraiser immediately. Don’t assume the deadline is gone. And don’t assume it isn’t.
What Realtors and Title Companies Get Wrong
This is the gap in the system that costs Orange County homeowners real money every year. It’s genuinely hard to assign blame — it’s not really anyone’s fault structurally, which somehow makes it worse.
Florida title agents are responsible for clean title transfer, lender compliance, and proper deed recording. They’re not tax advisors, and they have no statutory obligation to explain portability. The DR-501T is not in the standard closing packet. No one hands it to you at the table. Real estate agents face the same structural gap: tax filings that happen after closing sit outside what the transaction requires them to address. Some agents know the portability rules cold and explain them proactively. Many don’t — or they mention it in passing, one item in a conversation already stuffed with disclosures and loan terms. A casual “you might want to look into the portability thing” doesn’t land the same way as knowing you’re about to permanently forfeit $4,000 a year.
The fix is simple: treat DR-501T as a post-closing task you complete yourself, in the same category as updating your driver’s license or forwarding your mail. If you bought a new home in 2026, put March 1, 2027 in your calendar right now with a note that says “file portability form.” Call OCPA at 407-836-5044 to confirm what documents you need before you go. If you can submit online through ocpafl.org, do it early. The filing itself isn’t complicated. But it’s not automatic, it’s not triggered by your home purchase, and no one in your transaction is responsible for doing it for you. Buyers navigating Orange County’s new-construction market may also want to review what Orlando condo buyers must check before making an offer, which covers other post-closing tax and fee obligations that frequently catch new owners off guard.
Before March 1
If you bought a home in Orange County in 2026 and your prior home was homesteaded for any meaningful period, you almost certainly have a Save Our Homes differential worth transferring. The math isn’t hard. Find your prior year TRIM notice, look at the gap between just value and assessed value, and that’s your transferable amount. File DR-501T with OCPA — 200 S. Orange Ave., Suite 1700, or online at ocpafl.org — before March 1, 2027.
At current Orange County millage rates, a $200,000 differential saves around $4,000 annually from the first year of the new homestead onward. For an Orlando homeowner who bought before 2016 and is moving now, that’s a completely realistic number. It’s not a tax strategy. It’s filling out a form before a deadline. The only reason to miss it is not knowing it exists.
For filing hours, current online submission options, and your specific millage district rate, visit ocpafl.org or call 407-836-5044. For portability questions involving a move to Osceola County, contact the Osceola County Property Appraiser at 407-742-5000. For moves to Seminole County, contact the Seminole County Property Appraiser directly — confirm current contact details before filing.
