Property taxes are one of the biggest “quiet costs” of homeownership in Orlando. They are not a mortgage cost, but they often get paid through your monthly mortgage payment (via escrow), which means a property-tax increase can feel like a surprise payment jump even if your loan rate never changes.
This guide explains Orlando-area property taxes in plain English—how the bill is calculated, what “assessed value” really means, what your TRIM notice is telling you, why bills rise, how appeals work, and which exemptions matter most in Florida. It is written for general education and uses publicly available U.S. and Florida sources.
1) Orlando property taxes: the simple formula
In Florida (including Orlando/Orange County), your annual property tax bill is driven by three core pieces:
Annual Property Tax Bill ≈ (Taxable Value ÷ 1,000) × Total Millage Rate + Non-Ad Valorem Assessments
Key terms (plain English)
- Taxable Value: Your home’s value after exemptions (like Homestead) are subtracted.
- Millage Rate: The combined tax rate set by local taxing authorities.
- “1 mill” = $1 of tax per $1,000 of taxable value.
- Non-Ad Valorem Assessments: Flat or fee-based charges that are not calculated by millage (examples can include solid waste, stormwater, fire assessments, lighting districts—these vary by location).

Important Orlando detail: Your total bill depends on where the property sits (City of Orlando vs unincorporated Orange County vs another municipality), because each location can have different taxing authorities and rates.
2) “Market value” vs “assessed value” vs “taxable value”
A lot of confusion comes from mixing these up:
Market value (what buyers think about)
This is the “what would it sell for?” idea. It moves with the real estate market, interest rates, and buyer demand. It’s what you see on listing sites and comps.
Assessed value (what Florida property taxes usually lean on)
Florida’s assessed value is a value used for taxation and can be limited by caps (especially for Homestead properties). Two households can have similar market values but very different assessed values if one owner has had the home longer under Homestead caps.
Taxable value (what you actually get taxed on)
Taxable value = assessed value minus exemptions (Homestead, additional exemptions, etc.).
Florida’s exemption structure is a big reason why “my neighbor pays less tax than I do” happens so often—even for similar homes.
3) What is a TRIM notice, and why it matters
In Orange County, property owners receive a TRIM notice (Truth in Millage) that is not a tax bill. It’s an official notice that shows:
- Your property’s values (market/assessed/taxable)
- Your exemptions
- Proposed tax rates by each taxing authority
- An estimate of what your taxes would be under proposed rates
- When and where public budget hearings will happen for those taxing authorities
Then later, you receive the actual tax bill from the tax collector (typically in the fall/winter cycle).

Why you should read the TRIM notice
The TRIM notice is your best “early warning” for:
- Assessment changes
- Lost exemptions
- Proposed millage changes
- New or changed non-ad valorem assessments
If something is wrong (incorrect exemptions, incorrect classification, etc.), the TRIM window is when most owners act.
4) Why Orlando property tax bills go up (even if you didn’t buy or refinance)
Property tax bills rise for multiple reasons—some tied to your home, some tied to your local budget environment.
- A) Your taxable value increased
This can happen due to:
- Market value increases
- Assessed value increases (subject to caps if Homesteaded)
- Losing an exemption
- Changes to property classification (primary residence vs non-primary)
- B) The total millage rate changed
Local government budgets change year to year. If taxing authorities raise millage, the tax bill can rise even if values stayed flat. TRIM shows proposed changes authority-by-authority. (Source: Orange County Property Appraiser TRIM newsletter)
- C) Your non-ad valorem assessments changed
These can change based on service areas or local funding mechanisms, and they don’t scale the same way as millage.
- D) You bought recently (the “reset effect”)
When a home sells, the assessed value can “reset” closer to market—especially if the previous owner had long-term Homestead caps. New owners often see higher taxable values than the prior owner had, simply because the cap history doesn’t transfer the same way.
5) Florida Homestead: what it is, how it works, and why it’s a big deal
Florida’s Homestead rules can materially reduce taxable value and help limit annual increases for qualifying primary residences.
The Homestead exemption (up to $50,000 in many cases)
Florida provides a Homestead exemption up to $50,000 on a qualifying primary residence (structure and land), with the first portion applying broadly and part of the additional amount not applying to school taxes (details vary by levy).
Source: Florida Department of Revenue—general exemption guidance; Homestead up to $50,000; and official Homestead application (DR-501).
The Save Our Homes (SOH) cap (why taxes can differ between neighbors)
For many Homestead properties, annual assessed value increases are limited (often described as capped based on CPI changes or a maximum percentage cap). This is one reason long-time owners often have much lower assessed values than recent buyers for similar houses.
Practical implication (educational): If you’re comparing “property taxes” between two Orlando homes, you’re often comparing two different histories of assessment caps and exemptions—not just two similar properties.
6) Who sets Orlando-area property taxes?
Property taxes are typically shaped by multiple local authorities, such as:
- County government
- City government (if inside a city boundary)
- School board
- Special districts (water management, etc.)
The property appraiser generally determines value and exemptions; taxing authorities set millage; the tax collector sends bills and collects taxes. TRIM is designed to help taxpayers see this separation of duties. (Source: Orange County Property Appraiser TRIM newsletter)
7) Florida appeal basics: what you can challenge (and what you can’t)
Many homeowners assume “appeal” means “ask for a lower bill.” In reality, appeals generally target:
- Value (market/assessed value determination)
- Exemption decisions (approved/denied status)
- Classification issues (e.g., primary vs non-primary status)
- Certain portability or cap issues (where applicable)
Timing matters
Florida’s Value Adjustment Board (VAB) process is time-sensitive. Orange County VAB guidance emphasizes filing within the deadline window tied to the TRIM notice and other determinations.

Educational note: A strong appeal typically relies on clear evidence (factual errors, comparable sales, condition issues, classification mistakes) rather than general frustration with taxes.
8) Orlando-specific “why my bill changed” checklist (quick diagnostic)
If your Orlando/Orange County property taxes rose, these are common “first checks”:
- Did your Homestead exemption stay active?
Florida Homestead is powerful; losing it can move taxable value materially. (Source: Florida DOR Homestead guidance and application) - Did assessed value rise within cap rules?
Even capped increases can add up over time. - Did a non-ad valorem assessment change?
These can move for reasons unrelated to value. - Did local millage change?
The TRIM notice shows proposed and prior-year comparisons. - Did you buy recently?
New ownership can change the assessed baseline relative to the prior owner’s capped value.
9) What the data suggests about housing costs pressure (why taxes feel bigger now)
Property taxes don’t exist in a vacuum. They hit households alongside insurance, maintenance, utilities, and (for many) higher mortgage rates than in prior years.
At a county level, housing costs and values vary widely. The U.S. Census Bureau QuickFacts (derived from the American Community Survey) provides Orange County context such as median owner-occupied housing value and other housing indicators. (Source: U.S. Census Bureau QuickFacts—Orange County, FL)
Why this matters: When home values rise and local budgets rise, taxable values and millage pressure can translate into higher annual bills—especially for newer owners without years of capped assessments.
10) Escrow reality: why “property taxes in Orlando” can raise your monthly payment
Many homeowners pay property taxes through a mortgage escrow account, meaning the lender collects estimated taxes monthly and pays the bill when due.
If property taxes rise, two things can happen:
- Your monthly escrow portion increases to cover the higher bill.
- You may also see an escrow “shortage” adjustment if the prior year collection was too low.
Educational takeaway: Even though property taxes are “annual,” the impact often shows up in monthly payment changes.
11) Common myths about Orlando property taxes (and the reality)
Myth 1: “The property appraiser raises taxes.”
Property appraisers typically determine values and exemptions—not the tax rates. Taxing authorities set millage. TRIM exists partly to clarify this. (Source: Orange County Property Appraiser TRIM newsletter)
Myth 2: “If Zillow/Realtor.com says my home value is X, my property taxes will match that.”
Online estimates track market perceptions. Property tax values follow statutory rules, exemptions, caps, and local assessment processes. They don’t automatically match a portal estimate.
Myth 3: “Appealing means the county just lowers your bill.”
Appeals are about valuation/exemptions/classifications with evidence and deadlines—not general negotiation.
12) Orlando homeowner action steps
For many owners, the “best practices” are process-oriented:
- Read the TRIM notice carefully each year.
- Confirm exemptions (especially Homestead) are correct and active.
- Compare year-over-year values: market vs assessed vs taxable.
- Separate millage vs value vs assessments so you know what actually changed.
- If challenging something, watch deadlines and use evidence-based documentation. (Source: Orange County VAB petition timing guidance)
