What Is a Florida TRIM Notice? How to Read It, Meet Deadlines, and Prepare an Appeal

Your Florida TRIM Notice shows the proposed value of your property, tax rates, and estimated taxes. This guide walks you through every key field on the form, the 25-day VAB appeal deadline, and what to do in the first week to build a strong case.

Key Takeaways

• **25-day appeal window starts on mailing date**: Your deadline to file a VAB petition is 25 days from the mailing date printed on your TRIM notice, not from when you open it
• **TRIM is not a tax bill**: The Notice of Proposed Property Taxes (Form DR-474) shows the appraiser's proposed values and estimated taxes, but final bills come later after budget hearings
• **Check just value and exemptions immediately**: Verify the appraiser's market value estimate, your homestead and Save Our Homes cap, and look for errors in square footage or property details
• **Rolled-back millage reveals tax increases**: Compare the rolled-back rate (same revenue as last year) to the proposed rate to see whether your local government is actually raising taxes
• **Contact the appraiser before filing**: An informal review with the Property Appraiser can resolve obvious errors faster than a formal VAB hearing, but it does not extend your 25-day deadline

If you own property in Florida, a TRIM Notice is one of the most important pieces of mail you'll get each year. TRIM stands for "Truth in Millage," and the official form is called the Notice of Proposed Property Taxes (Form DR-474). The notice tells you the property appraiser's proposed values, the proposed tax rates from each local government, estimated taxes, and where and when budget hearings will happen. It also starts the clock for appealing your assessment. (See Florida Department of Revenue TRIM materials: https://floridarevenue.com/property/Documents/dr474.doc and https://floridarevenue.com/property/Documents/trimregwb.pdf.)

Why this matters: if the appraiser's value looks too high, you have a limited window to challenge it. Understanding your TRIM Notice gives you the chance to fix mistakes or launch a formal appeal to the Value Adjustment Board (VAB).

The legal basics — plain language version

• The TRIM process comes from Florida law. Chapters 193 and 194 cover how property is assessed and how appeals work. Chapter 193 explains how values get set; Chapter 194 explains the appeal process and deadlines. (Florida Statutes: https://www.flsenate.gov/Laws/Statutes/2022/Chapter193/All and https://www.flsenate.gov/Laws/Statutes/2024/194.011.)
• Truth in Millage timing rules are in s. 200.065 and in the Department of Revenue TRIM workbook. These rules set the timing for notices and hearings. (See s. 200.065: https://www.leg.state.fl.us/statutes/index.cfm?Appmode=DisplayStatute&URL=0200-0299/0200/Sections/0200.065.html and DOR guide: https://floridarevenue.com/property/Documents/homeownerguidemillage.pdf.)

Typical timeline — when you'll get the notice and how deadlines work

• When TRIM notices are mailed: Counties usually mail TRIM Notices in mid-to-late August. The Department of Revenue requires notices be mailed in time for the public hearing process, which commonly results in mailing by about August 24 each year. (See TRIM Compliance Workbook: https://floridarevenue.com/property/Documents/trimregwb.pdf.)
• VAB filing deadline: You must file a petition with the Value Adjustment Board within 25 days after the TRIM Notice mailing date printed on your notice. That 25-day window comes from Chapter 194. Always use the mailing date on your notice to compute the deadline—count 25 days from that date. (Statute: https://www.flsenate.gov/Laws/Statutes/2024/194.011.)
• County variations: The 25-day rule is statewide, but exact calendar dates vary because counties mail notices on slightly different days. Counties publish their exact deadlines each year; check your county's property appraiser page. Examples: Miami-Dade, Broward, and Hillsborough post TRIM and appeal info annually: Miami-Dade TRIM page (https://www.miamidadepa.gov/pa/propertytrimnotice.asp), Broward TRIM (https://bcpa.net/trim.asp), Hillsborough Truth in Millage (https://www.hcpafl.org/Property-Info/Truth-In-Millage).

Key fields on your TRIM Notice — what to check right away

When your TRIM Notice arrives, scan and verify these items immediately:

• Mailing date: This is the most important date. Your 25-day appeal window starts here.
• Parcel and owner information: Make sure the property listed is yours and the address is correct.
• Just value (market value) and assessed value: The appraiser's opinion of market value is shown. If this looks wrong, gather evidence. (Form DR-474: https://floridarevenue.com/property/Documents/dr474.doc.)
• Taxable value: This is the value after exemptions and assessment caps (like Save Our Homes) are applied.
• Exemptions and assessment limitations: Check that homestead, senior, or other exemptions are listed correctly and that any Save Our Homes cap or portability transfer appears if applicable.
• Rolled-back millage and proposed millage: The rolled-back rate shows the tax rate that would bring in the same revenue as last year. Compare it to the proposed rate to see whether your local government is increasing taxes. (Homeowner guide: https://floridarevenue.com/property/Documents/homeownerguidemillage.pdf.)
• Proposed taxes: Your estimated dollar amount of taxes under the proposed budgets. Compare last year's taxes to the proposed amount.
• Public hearing dates, times, and locations: These are the budget hearing dates for the county, city, school district, and any taxing authorities.
• VAB filing instructions and fees: The notice will tell you how to file a petition and where to get forms. It often suggests contacting the property appraiser first for an informal review.
• Non-ad valorem assessments: If you pay special assessments (like sanitation or stormwater), those often appear separately—check accuracy.

(You can see a sample DR-474 and field explanations in the DOR form and TRIM workbook: https://floridarevenue.com/property/Documents/dr474.doc and https://floridarevenue.com/property/Documents/trimregwb.pdf.)

What you should do in the first 7 days

• Read the mailing date and mark your calendar for 25 days later. That's your VAB deadline.
• Compare the TRIM values and exemptions to last year's bill. Note any big increases.
• If you see an obvious error (wrong square footage, wrong exemption, wrong ownership), contact your county property appraiser immediately and request an informal review. Counties encourage this first step. (See Miami-Dade appeals info: https://www.miamidadepa.gov/pa/appealingassessmentVAB.asp.)
• If the appraiser won't fix it, prepare to file a petition with the VAB within the 25-day window.

Tips to prepare a stronger appeal

• Gather comparable sales: Look for recent sales of similar nearby homes. Sales within the last 6–12 months help most.
• Document physical condition: If the property has damage, deferred maintenance, or major differences from comps, photograph and document it.
• Check exemptions: If a homestead exemption was removed or reduced, collect documents (deeds, utility bills) to prove eligibility.
• Keep copies: Save the TRIM Notice, appraisal records, photos, repair estimates, and any emails or letters with the appraiser.
• Consider timing: An informal conference with the appraiser can sometimes fix issues faster and cheaper than a formal VAB hearing.
• Know filing methods and fees: Counties vary on filing fees and whether you can file online, by mail, or in person. Check your county's VAB instructions. (Examples: Broward: https://bcpa.net/value.asp; Hillsborough appeal info: https://www.hcpafl.org/Property-Info/The-Appeal-Process.)

Timeline at a glance

• Mid–late August: TRIM Notices are usually mailed (dates vary by county). (DOR TRIM workbook: https://floridarevenue.com/property/Documents/trimregwb.pdf.)
• Day TRIM mailed: Start counting the 25 days.
• Within 25 days of mailing: File a petition with your county VAB (if you plan to contest value or exemptions). (See s. 194.011: https://www.flsenate.gov/Laws/Statutes/2024/194.011.)
• After filing: Schedule or await VAB hearing; follow your county's instructions for evidence submission and hearing format.

Final note — why you shouldn't wait

A TRIM Notice gives you a short, fixed window to act. If you miss the 25-day deadline, you usually lose the right to challenge that year's assessment. Read the notice, check the mailing date, and start with an informal talk with your property appraiser if anything looks off. If you still disagree, file with the Value Adjustment Board before the deadline.

The laws and forms behind TRIM are technical, but the steps you need to take are straightforward: read, verify, contact the appraiser, and file on time if needed. If you want county-specific filing steps and a checklist of evidence to gather, use your county property appraiser website or the Department of Revenue TRIM materials listed above.

Frequently Asked Questions

What does TRIM stand for in Florida property taxes?

TRIM stands for Truth in Millage. The TRIM Notice, officially called the Notice of Proposed Property Taxes (Form DR-474), shows your property's assessed value, proposed tax rates from each local government, estimated taxes, and public hearing dates.

When are Florida TRIM Notices mailed each year?

Florida counties typically mail TRIM Notices in mid-to-late August. The exact date varies by county, but the Department of Revenue requires notices be mailed in time for the public hearing process, which commonly results in mailing by about August 24.

How long do I have to appeal my TRIM Notice assessment?

You have 25 days from the mailing date printed on your TRIM Notice to file a petition with your county's Value Adjustment Board (VAB). This deadline comes from Florida Statute Chapter 194 and applies statewide.

What is the difference between just value, assessed value, and taxable value on a TRIM Notice?

Just value is the property appraiser's estimate of your property's market value. Assessed value may be lower if you have assessment caps like Save Our Homes. Taxable value is the assessed value minus any exemptions such as homestead, and is the amount used to calculate your tax bill.

Should I contact the property appraiser before filing a formal VAB appeal?

Yes. Counties encourage homeowners to request an informal review with the property appraiser first. This can resolve errors like wrong square footage, missing exemptions, or incorrect ownership faster and at no cost before you need to file a formal VAB petition.

What evidence do I need to appeal my Florida property assessment?

Gather comparable sales from the last 6 to 12 months of similar nearby properties, photographs documenting your property's condition, documents proving exemption eligibility, and copies of your TRIM Notice and past tax bills. Keep all correspondence with the property appraiser as well.
