Monroe County Property Tax Appeal, Florida

Travis BunnTravis Bunn·Updated July 22, 2026

Monroe County is the southernmost county in Florida, encompassing the famous Florida Keys from Key Largo to Key West. With a 2026 population estimated at approximately 78,800, the county has a median home value of $503,900 and an effective property tax rate of 0.53%, resulting in a median annual property tax bill of $2,673. While Monroe County's effective rate is significantly below Florida's state median of 0.86% and well below the national median of 1.02%, the county ranks 235th nationally in median property taxes due to its extremely high property values. Property tax appeals are particularly important here given the county's expensive real estate market, where even modest overassessments can result in substantial overpayments.

On the typical Monroe County home, valued near $503,900 at the county’s effective tax rate of 0.53%, an over-assessment of even 10% means you are overpaying year after year until you appeal it. Here is how to find out if yours qualifies.

2026 Appeal Deadline: 25 days from the TRIM notice mailing date (typically early to mid-September 2026)

Monroe County mails TRIM (Truth in Millage) notices in August each year. Property owners have exactly 25 days from the mailing date (not the date you receive it) to file a petition with the Value Adjustment Board. For 2026, if TRIM notices mail around August 11-18, the deadline would fall in early to mid-September. This deadline is strictly enforced with no extensions.

How Monroe County Assesses Property

100%of market value

Assessed by: Monroe County Property Appraiser

Assessment cycle: annual

Notices typically mailed: August (TRIM notices)

Florida law requires Monroe County to assess properties at 100% of just (market) value as of January 1st each year, subject to Save Our Homes and other constitutional protections. This means your assessed value should equal your property's fair market value. For example, if your home's market value is $503,900 (Monroe County's median), at Florida's 100% assessment ratio your assessed value would be $503,900, resulting in approximately $2,670 in annual taxes at the county's effective rate of 0.53%. However, homestead properties with Save Our Homes protection may have assessed values capped at 3% annual increases, creating a difference between market and assessed values.

The Appeal Process

Appeals are heard by the Value Adjustment Board (VAB). Monroe County VAB hearings are conducted by independent Special Magistrates (licensed appraisers or attorneys) in a quasi-judicial setting. You'll have 5-15 minutes to present your case with evidence. The magistrate makes a recommendation to the full VAB board, which consists of two county commissioners, one school board member, and two citizen members.

1

Step 1: Review your TRIM notice carefully when it arrives in August. Compare the assessed value to recent comparable sales and check for errors in property details (square footage, bedrooms, lot size). Note the 25-day filing deadline printed on the notice.

2

Step 2: Request an informal review with the Monroe County Property Appraiser's office at (305) 292-3420 before filing a formal appeal. Many disputes are resolved at this stage without a hearing. Bring comparable sales data, photos, and documentation of any property issues.

3

Step 3: If informal review doesn't resolve your concerns, file Form DR-486 with the Monroe County Clerk of Court - VAB within 25 days of the TRIM notice mailing date. Include the $50 filing fee per parcel (no fee for exemption denials). Attach all supporting evidence: comparable sales, photos, repair estimates, and appraisal reports.

4

Step 4: Attend your scheduled hearing before a Special Magistrate appointed by the Value Adjustment Board. Hearings typically occur in October-November. Present your evidence professionally in 5-15 minutes, focusing on comparable sales and factual errors. The magistrate will make a recommendation to the VAB.

5

Step 5: The Value Adjustment Board reviews the Special Magistrate's recommendation and issues a final decision. If your appeal is denied, you can appeal to circuit court within 60 days, or if you prevail but the Property Appraiser disagrees, they may appeal to circuit court as well.

Frequently Asked Questions

What is the deadline to appeal my property taxes in Monroe County for 2026?
You must file your property tax appeal within 25 days from the mailing date of your TRIM (Truth in Millage) notice, not from when you receive it. Monroe County typically mails TRIM notices in mid-August, making most 2026 deadlines fall in early to mid-September. The exact deadline date is printed on your TRIM notice. This deadline is strictly enforced by Florida law with no extensions or exceptions, so if you file on day 26, your appeal will be automatically denied regardless of merit.
How much does it cost to file a property tax appeal in Monroe County?
The filing fee for a property tax value appeal in Monroe County is $50 per parcel, payable to the Monroe County Clerk of Court. However, if you are appealing the denial of a homestead exemption or other ad valorem tax exemption, no filing fee is required. The fee can be waived if you demonstrate eligibility for temporary assistance through the Department of Children and Family Services by providing appropriate documentation with your petition. Make checks payable to Monroe County Clerk of Court and submit with Form DR-486.
How do I file a property tax appeal in Monroe County?
To file an appeal, complete Florida Form DR-486 (Petition to the Value Adjustment Board) and submit it to the Monroe County Clerk of Court - VAB within 25 days of your TRIM notice mailing date. You can file in person at any Clerk office location in Key West, Marathon, or Plantation Key, or mail to P.O. Box 1980, Key West, FL 33041-1980. Include the $50 filing fee and all supporting evidence. Note that Monroe County does not accept petitions by email or fax, and postmarks are not sufficient - the petition must be physically received by the deadline.
What is the homestead exemption worth in Monroe County?
Florida's homestead exemption can reduce your Monroe County property's taxable value by up to $50,000. The first $25,000 applies to all property taxes including school district taxes, while the additional $25,000 applies to assessed values between $50,000 and $75,000 (excluding school taxes). For a Monroe County home at the median value of $503,900, the full homestead exemption could save approximately $250-265 annually at the 0.53% effective rate. Once granted, the exemption automatically renews each year as long as you continue occupying the property as your primary residence. Apply by March 1st at the Monroe County Property Appraiser's office.
What happens at a Value Adjustment Board hearing in Monroe County?
Monroe County VAB hearings are conducted by independent Special Magistrates who are licensed real estate appraisers or attorneys hired by the board. The hearing is a quasi-judicial proceeding where you'll have approximately 5-15 minutes to present your evidence showing your property is overvalued. You should bring comparable sales data, photographs, repair estimates, and any other documentation supporting your claim. The Property Appraiser's office will also present evidence defending their assessment. After hearing both sides, the Special Magistrate makes a recommendation to the full Value Adjustment Board, which consists of two county commissioners, one school board member, and two citizen members who make the final decision.
Should I try to resolve my appeal informally before filing with the VAB in Monroe County?
Yes, Monroe County strongly encourages property owners to schedule an informal review with the Property Appraiser's office before filing a formal VAB petition. You can call (305) 292-3420 to request a meeting where you can present comparable sales, photos, and other evidence. Many assessment disputes are resolved at this informal stage, saving both time and the $50 filing fee. However, requesting an informal review does not extend your 25-day deadline to file with the VAB, so if the informal meeting doesn't resolve your concerns, you must still file your DR-486 form before the deadline expires.
Can I appeal my Monroe County property taxes if I have Save Our Homes protection?
Yes, you can and should appeal even with Save Our Homes (SOH) protection if you believe your property's market value is overstated. While SOH limits your assessed value increases to 3% annually for tax purposes, the Property Appraiser still determines your property's full market value each year. If you successfully appeal and reduce the market value, you'll benefit when you eventually sell and move, as the SOH differential is calculated based on the difference between market and assessed values. A lower market value today means more portability benefit to transfer to your next Florida homestead. Additionally, new homeowners without SOH protection definitely benefit from appealing during their first year.
What evidence do I need to win a property tax appeal in Monroe County?
The strongest evidence for Monroe County property tax appeals includes recent comparable sales of similar properties in your area sold within the past 6-12 months. Focus on properties with similar size, age, condition, location, and features. Also gather photographs documenting any property condition issues, deferred maintenance, or damage; written repair estimates from licensed contractors for needed work; and documentation of any factual errors in the property record such as incorrect square footage, wrong number of bedrooms, or features you don't have. Professional appraisals carry weight but aren't required if you have strong comparable sales data. Organize your evidence professionally and be prepared to present it concisely at your hearing within the 5-15 minute timeframe typically allowed.
