When the pale green envelope from the Orange County Property Appraiser lands in your mailbox in late August, most homeowners give it a ten-second glance and file it under the refrigerator magnets. That’s an expensive habit.
The Truth in Millage notice—TRIM, in Florida tax shorthand—is not a bill. It’s not a courtesy. It is the starting gun on a 25-day legal window during which you can formally challenge your property’s assessed value before the Orange County Value Adjustment Board. Miss that window and you forfeit your appeal rights until next August, regardless of how wrong the numbers are. The deadline is fixed by state statute, not county policy, and no one in the system is required to remind you it’s running.
This piece is designed to be read the week your notice arrives. By the end of it, you’ll know what every number on that form actually means, whether you have a legitimate basis to contest, exactly what to file and where, and what to expect if your case goes to a hearing.
What to Do the Moment Your Notice Arrives
Write down the mailing date printed on the envelope. Your petition deadline is 25 days from that date—not from the day you opened it. In 2025, Orange County Property Appraiser Amy Mercado’s office mailed notices on approximately August 24, putting the deadline around September 18. For 2026, verify the exact mailing date at ocpafl.org once notices go out; it shifts slightly each year. Then read the notice carefully against the guidance below before deciding whether to act.
Three Numbers on the Notice and Why They’re All Different
Every Orange County TRIM notice prints three dollar figures in the assessment box. The gap between them confuses homeowners every year, and it’s easy to see why.
Just value is the Orange County Property Appraiser’s estimate of what your home would sell for on the open market as of January 1. This comes from OCPA’s mass-appraisal model, which uses recent comparable sales, neighborhood trend data, and property characteristics. Just value is meant to reflect actual market value. Orange County saw dramatic appreciation from 2020 through 2023, so just values in many neighborhoods rose sharply and haven’t fully retreated.
Assessed value is the figure your taxes are actually calculated on. For most longtime homeowners it’ll be substantially lower than just value—Florida’s Save Our Homes law is why. Once you have homestead exemption, the annual increase in assessed value is capped regardless of what the market does. The result, after several years of ownership, is a growing cushion between what your home is worth and what you’re taxed on. This is the most consequential number on the notice for your actual tax bill. It’s also not the number you directly challenge at the VAB, which surprises a lot of people.
Taxable value is what remains after exemptions are subtracted from assessed value. Most commonly that’s the standard $25,000 homestead exemption and, for eligible homeowners, a second $25,000 that applies to non-school millage. Taxable value is what gets multiplied by your millage rate to produce your bill. Just value, by contrast, is the number the Value Adjustment Board can address—and it’s the starting point for everything else.
How the Save Our Homes Cap Appears on Your Notice
Florida’s Save Our Homes law, codified at §193.155, F.S., caps the annual increase in assessed value for homesteaded properties at the lesser of 3 percent or that year’s Consumer Price Index change. When CPI rises 4 percent and your neighborhood jumps 12 percent, your assessed value still only moves 3 percent. The 2025 cap held at 3.0 percent.
On your TRIM notice, the difference between just value and assessed value is the Save Our Homes differential. That gap is real money.
A concrete example: a home in the College Park area carries a current just value of $420,000. The owner has had homestead exemption for several years and has ridden through the 2020–2023 appreciation run with assessed value held to 3 percent annually. The assessed value on the notice reads $310,000. That $110,000 gap is not an error—it’s the accumulated benefit of years of capped increases while the market ran.
What does $110,000 in sheltered value actually save? Orange County’s combined millage rate for most unincorporated residential properties runs roughly 19 mills, though it varies by municipality and special district—use the rate printed on your own notice. At 19 mills, $110,000 in sheltered value is about $2,090 in annual savings. Year after year.
The neighborhoods where these differentials grew largest after the appreciation surge are exactly the ones that appreciated fastest. Windermere and the Dr. Phillips corridor saw extraordinary gains on waterfront and golf-course properties. Baldwin Park moved sharply between 2019 and 2022. Pockets of College Park and Delaney Park outran what the cap could follow. Longtime owners in those areas are sitting on differentials that may exceed $100,000—sometimes much more on high-value properties. Recent buyers next door have nothing.
Save Our Homes cuts against what many homeowners assume in two important ways.
First: new buyers lose the protection entirely in year one. If you purchased your Orange County home in 2023 or 2024, your assessed value was reset to just value at the time of sale. You inherit no differential from the previous owner. Your cap starts building from zero. This is why your TRIM notice, as a recent buyer, shows an assessed value essentially equal to just value. This is why your tax bill is dramatically higher than your neighbor’s for an identical house. I’ve heard from homeowners who were convinced their notice was misprinted. It wasn’t. That’s just how the statute works, and it explains more disputes than any other single factor in Orange County.
Second: if you sell and buy another Florida homesteaded property, you may be eligible to transfer your accumulated differential to the new home through portability. The portable benefit is capped at $500,000 and requires a separate application with OCPA by March 1 of the year following your move. If you bought a new primary residence in Orange County in 2024 and missed the March 1, 2025 deadline, that transfer opportunity is gone. Calendar March 1 now.
How to Tell Whether Your Notice Contains an Error Worth Contesting
This is the most important filter in this piece. Filing a Value Adjustment Board petition costs $15 and several hours of your time. Filing one with no realistic chance of success wastes the magistrate’s time and yours.
Longtime homeowners whose assessed value is already well below market value should generally not file on market-value grounds. Here’s why: if your just value is $420,000 and your assessed value is $310,000, even if you believe your home is only worth $380,000, winning that argument at the VAB doesn’t touch your tax bill. You’d need to drive just value below your assessed value before it matters—a high bar that’s the wrong strategy for most homeowners sitting on a substantial Save Our Homes differential.
The situations that genuinely warrant a challenge are more specific.
Your just value exceeds what you could realistically sell the home for. This most commonly affects recent buyers who paid near the top of a market that has since softened, or owners of homes with condition problems the mass-appraisal model didn’t catch. If comparable sales in your immediate neighborhood over the past six months support a materially lower value—typically more than 5 to 10 percent lower to make the fight worthwhile—you have something to work with.
A homestead or other exemption is missing or incorrectly applied. Check the exemption line carefully. If you’ve owned your home for years and the standard $25,000 homestead exemption isn’t showing, that’s an error OCPA can typically correct quickly. It hits your taxable value directly.
The property is misclassified. Wrong square footage, incorrect bed and bath counts, agricultural classification errors, tangible personal property mistakes—these are all grounds for a challenge that have nothing to do with market value and everything to do with whether OCPA has basic facts right.
Condition or deferred maintenance the model can’t see. Worth pausing on this one. OCPA’s mass-appraisal model processes thousands of properties using public records, permit history, and neighborhood comps. It cannot see that your HVAC failed last fall. It cannot see that your roof is at the end of its rated life, that your foundation has settling cracks, or that every comp in your neighborhood that sold recently was fully renovated while yours has original contractor-grade finishes throughout. If your home’s condition puts it meaningfully below the average for its comp set, you can document that gap with photos, repair estimates, and contractor assessments. That’s exactly the kind of evidence that can move a magistrate. For broader context on what roof condition and age can mean for your finances, our coverage of what Orlando homeowners are actually paying for a new roof in 2026 illustrates how significant deferred maintenance can be as a dollar figure.
If none of these apply—if your assessed value is already well below market and your exemptions are correctly listed—your TRIM notice is not an opportunity to contest. File it somewhere more accessible than the refrigerator, use it as your annual tax budget checkpoint, and move on.
The Free Step Most Homeowners Skip
Before filing a formal petition, Orange County homeowners have access to something that’s poorly publicized and genuinely useful: a free informal conference with an appraiser at the Orange County Property Appraiser’s office.
OCPA is at 200 S. Orange Ave., Suite 1700, Orlando. The main number is 407-836-5044. Walk-ins are accommodated during normal business hours, but calling ahead is wise in the weeks right after notices go out, when volume spikes. Staff appraisers can review your specific parcel, look at the underlying data, and in some cases correct errors or reduce values on the spot. No cost. No formal hearing.
A missing exemption, a data entry error on square footage, a condition issue that’s obvious from photos—all of these are things OCPA staff can address directly and quickly. Many legitimate disputes end right here.
The critical caveat: the informal conference does not stop the 25-day VAB clock. If you schedule a conference on September 10 and the petition deadline is September 18, you may need to file the formal petition simultaneously as a protective measure, then withdraw it if the informal process resolves your issue. Calling OCPA’s office does not buy you more time with the VAB clerk.
The 25-Day Deadline, the Form, and Where to File
Florida law gives homeowners 25 days from the date TRIM notices are mailed—not delivered, mailed—to file a petition with the Value Adjustment Board. Every year, homeowners find the notice buried in vacation mail on September 15 and assume they have 25 days from that moment. They don’t.
The form is DR-486, available through the Orange County VAB clerk or at floridarevenue.com.
File through the Orange County Value Adjustment Board, administered by the Orange County Clerk of Courts. Use the portal at myorangeclerk.com or call the VAB clerk at 407-836-5115 to confirm current procedures before the deadline. The process is updated annually—don’t assume last year’s instructions still apply. The filing fee is $15 per parcel; verify the current amount with the VAB clerk before filing.
Submit supporting documentation with your petition. Pull comparable sales from ocpafl.org—OCPA’s own data carries credibility with magistrates. Include photos of condition issues. If you’re arguing deferred maintenance, attach a contractor estimate. Write a brief statement of your grounds. You don’t need to present your full case at filing; you do that at the hearing. But submitting initial documentation establishes your position and sometimes moves resolution faster before a formal proceeding becomes necessary.
What a VAB Hearing Actually Looks Like
If your petition isn’t resolved before the hearing, your case goes before a special magistrate—not a judge, not a courtroom. Orange County’s VAB magistrates are licensed Florida appraisers or property tax attorneys appointed to hear cases and make recommendations to the full board. The proceedings are administrative. If you’re picturing a trial, stop. It’s closer to a structured meeting in a conference room: a table, a magistrate, a county appraiser on the other side, and you. Less intimidating than people expect, though the county’s appraiser will show up prepared, so you should too.
Expect your hearing to be scheduled between January and April of the following year. Orange County processes a significant volume of petitions annually. A petition filed in September will not be heard in October. Accept that timeline now.
Bring comparable sales from ocpafl.org. Identify sales of genuinely similar properties—similar square footage, age, condition, and location, closed in the six months before January 1 of the tax year in question. Using the appraiser’s own public database carries real weight with a magistrate. Bring dated photographs documenting condition issues: deferred maintenance, functional obsolescence, physical depreciation that distinguishes your home from the comps OCPA used. Contractor estimates for significant deficiencies help. A licensed independent appraisal is the strongest evidence available, but commission one only if the potential savings over multiple years justify the cost—for most straightforward residential cases, they don’t.
Organize your argument in a written summary. Magistrates hear many cases in a day. One clear page that walks through your evidence is practical, not theatrical.
Florida law places the initial burden on you to overcome the presumption that OCPA’s assessment is correct. That doesn’t mean you need a professional appraiser—it means you need credible, organized evidence. Magistrates see plenty of self-represented homeowners. Prepared ones with solid comparables win.
Property tax consulting firms in Orange County will take residential cases on contingency, typically at 30 to 40 percent of first-year tax savings. For most straightforward residential petitions, that fee will exceed what a prepared homeowner would recover on their own. For complex commercial cases, or for owners who genuinely can’t invest the time, a contingency arrangement makes sense. Do the math before signing anything.
After the hearing, the magistrate issues a recommendation to the full VAB. If you disagree with the outcome, you have 60 days to appeal to circuit court—a formal legal proceeding that almost always involves an attorney, and rarely worth pursuing for the dollar amounts typical in residential cases.
Exemptions and Why You Can’t Add New Ones Through a VAB Petition
This is one of the most common misconceptions about the process. A homeowner turns 65 in the spring, receives their TRIM notice in August, reads about the senior exemption, and assumes they can add it to their petition. They can’t.
Exemption applications run on a completely separate track with a completely separate deadline: March 1 of the tax year for which you want the exemption applied. Homestead, senior, widow/widower, disability, deployed military—all of them. A VAB petition filed in September addresses the assessed value for a year whose exemption window has already closed nine months earlier. The two processes don’t intersect.
What you should do right now is use your TRIM notice as an exemption checklist. Confirm that every exemption currently shown is correct. Then ask whether any new exemptions apply to your situation and whether you need to act by March 1.
The standard homestead exemption saves roughly $475 annually at a 19-mill rate—it requires only that the property be your primary residence and that you establish Florida domicile. The additional $25,000 exemption applies to non-school millage only, worth approximately $285 per year. The senior low-income exemption provides up to $50,000 in additional exemption for homeowners 65 or older with household income below approximately $36,614 for 2025 (adjusted annually; verify at ocpafl.org). Widow and widower exemptions reduce assessed value by $500. Disability determinations from FDVS or Social Security can qualify you for partial or full exemption depending on circumstances. Deployed military service members and first responders with total and permanent line-of-duty disabilities have their own pathways.
If you turned 65 this year, were widowed, sustained a qualifying disability, or became newly eligible for any exemption, put March 1 in your calendar today. Contact OCPA at 407-836-5044 before that date. The deadline is statutory and is extended in only very narrow circumstances.
One more check: if your homestead exemption itself is missing—which can happen after a refinance, estate transfer, or ownership change that didn’t trigger automatic re-application—file for reinstatement with OCPA immediately, separately from any VAB action. A missing homestead exemption is a direct hit to your bill and warrants fast action outside the formal appeal system. Don’t wait for a hearing date.

Millage Rate Your total millage rate is printed on your TRIM notice and reflects county, municipal, school board, and special district levies combined. For most unincorporated Orange County residential properties it runs in the range of 18 to 20 mills, but it varies meaningfully by municipality and district. Use the rate on your own notice for any calculation.
Senior Exemption Income Threshold Approximately $36,614 for 2025; adjusted annually. Verify the current figure at ocpafl.org before applying.
The TRIM notice is one of the few moments each year when Florida’s property tax system puts real information in your hands and gives you a legal mechanism to act on it. The window is 25 days. That’s it. If you have a legitimate basis to contest—a just value that exceeds what your home would actually sell for, a missing exemption, a condition the model didn’t capture—the VAB process is more accessible than it sounds. If you don’t have a legitimate basis, check your exemptions, mark March 1 on your calendar, and put the notice somewhere you can find it next year.
