Your Windermere home has appreciated, which is wonderful. The market values keep climbing, and your property is worth more than ever. Then you open your mail in August and see your TRIM notice (Truth in Millage) from Orange County, and the assessment has jumped significantly. Your first instinct is probably to accept it as the cost of owning valuable real estate, but here's what many homeowners don't realize: you don't have to.

Research shows that 30 to 60 percent of U.S. residential properties are overassessed, yet fewer than 5 percent of homeowners ever file an appeal. If your property taxes in Windermere feel like they've skyrocketed, you likely have options. The good news is that while you can't negotiate the tax rate itself, you absolutely can challenge the assessed value of your property.

Understanding Your Assessment Notice

When your TRIM notice arrives each August, it's not actually a bill yet. This isn't your tax bill — it's a proposal showing what your taxes could be. This notice is your opportunity window to review and potentially challenge the county's valuation before taxes are finalized.

In Orange County, where Windermere is located, with a median home price of $536,608, homeowners in Windermere face property tax bills that can vary significantly, ranging from $4,559 at the 25th percentile to $18,250 at the 90th percentile. These numbers highlight just how much your individual assessment matters to your actual tax obligation.

When you look at your notice, pay close attention to what's listed about your property. The assessor uses the information on your record card to determine your property's market value. The card contains information like square footage, the condition of the property, and property features. If any of this information is incorrect, the assessor's valuation could be off.

Who Decides Your Assessment Matters Less Than You Think

Many homeowners assume their local tax assessor sets their tax rate, but that's not quite how it works. The Property Appraiser establishes the value of property in Orange County and approves exemptions, including Homestead. Based on the values and exemptions assessed, the Property Appraiser certifies the Tax Roll to the Tax Collector. The actual tax rate is set by the county commissioners, school board, and other taxing authorities. What you can control is your property's assessed value, which directly impacts your bill.

Start With an Informal Conference

Before filing a formal appeal, consider reaching out to Orange County's Property Appraiser's Office. Start with an informal review. Many errors are corrected without a formal hearing. If unresolved, you can petition the Value Adjustment Board (VAB) — an independent review body.

An informal conference with the appraiser's office is a conversation, not a legal proceeding. Sometimes simple errors like incorrect square footage or missing information get corrected right away without you needing to file a petition. For Orange County, you can schedule this meeting by contacting the Property Appraiser at (407) 836-5205 for residential properties.

The Formal Appeal Process in Orange County

If the informal review doesn't resolve your concerns, you can file a formal petition with the Value Adjustment Board (VAB) is an independent board of local government officials who hear and decide property valuation disputes.

The appeal deadline in Orange County is strict. The filing deadline for petitions related to valuation issues is no later than 5:00 p.m. (11:59 p.m. if filed online) on the 25th day following the mailing of the Truth in Millage (TRIM) Notice. Since your TRIM notice typically arrives in August, this usually means you have until mid-September to file your petition.

The VAB clerk's office can be reached at (407) 836-5447 if you have questions about the process. You can file your petition in person, by FedEx, or UPS at: Orange County Value Adjustment Board, 109 E. Church St, 4th Floor Suite 450, Orlando, FL 32801. They also accept online filings, which many people find more convenient.

What Evidence You'll Need

The strongest evidence in a property tax appeal is data on comparable properties. The most convincing evidence in a property tax appeal is data on comparable properties (comps) that sold for less than your TRIM Notice Market Value. Without strong comparable sales data, even legitimate concerns about your assessment are difficult to prove to a Value Adjustment Board magistrate.

Look for recent sales of similar properties in your Windermere area or surrounding neighborhoods that sold for less than your assessed value. Properties with similar square footage, age, condition, and features are the most helpful. You'll also want to document any issues that might lower your property's value, such as needed repairs, property condition problems, or unique challenges that aren't reflected in the assessment.

Industry studies suggest 40%–60% of property tax appeals lead to some reduction in assessed value. That makes the effort worthwhile, especially for higher-value homes like many in Windermere.

Important Things to Remember

Even if you're appealing your assessment, you should still make your property tax payments on time. If you petition the VAB, you must still pay all your non-ad valorem assessments and the required portion of your ad valorem taxes before they become delinquent, usually on April 1. Pay taxes to avoid penalties while your appeal is in process. If your appeal succeeds, you'll typically receive a refund for any overpayments.

Once you file your VAB petition, don't expect an immediate decision. VAB hearings are generally scheduled between November and April of the following year. From the date of filing to the conclusion of the hearing, property owners should expect a timeline of approximately seven (7) months. This gives you plenty of time to gather evidence and prepare your case.

When You Should Seriously Consider an Appeal

Not every tax increase warrants an appeal, but certain situations make an appeal more likely to succeed. If your property's assessment has increased significantly more than nearby comparable properties, if there are factual errors in your property description, or if recent comparable sales show your home is valued higher than the market dictates, those are all legitimate reasons to appeal.

For Windermere properties specifically, consider whether your home's condition and features truly match the assessed value. The Windermere real estate market is dynamic, and assessments sometimes lag behind or misrepresent current market conditions. If you suspect your property is overvalued, that's your signal to investigate further.
