Florida TRIM Notice 2026: What to Do When Your Property Tax Assessment Arrives

Every August, roughly 10 million Florida property owners open a single-page notice from their county property appraiser and have exactly 25 days to decide whether to fight it. It is called the TRIM notice, and it is the most important piece of property tax mail you will get all year. Most homeowners skim it, assume the number is final, and file it away. It is not final. You have a statutory right to challenge it, and if your assessment is too high, the window to do something about it closes fast.

Here is exactly what a Florida TRIM notice is, when it arrives in 2026, what to look for, and how to file a petition with the Value Adjustment Board before the deadline.

What a TRIM notice actually is

TRIM stands for Truth in Millage. Your TRIM notice, formally the Notice of Proposed Property Taxes, is mailed by your county property appraiser under Florida law. It is not a bill. It is a preview: it tells you what the appraiser thinks your property is worth, what exemptions have been applied, what the proposed tax rates (millage) from each taxing authority are, and roughly what your tax bill will be if nothing changes.

The notice exists to give you a chance to react before the tax roll is finalized. That chance is the whole point, and it has an expiration date printed right on the page.

When Florida TRIM notices mail in 2026

County property appraisers mail TRIM notices in mid-to-late August 2026. Exact dates vary by county, but most Florida homeowners will have the notice in hand by the last week of August. Miami-Dade, Broward, Palm Beach, Hillsborough, Orange, Pinellas, and the other large counties all follow the same August cycle.

The critical date is not the mailing date. It is the petition deadline, which under Florida Statutes §194.011(3)(d) is 25 days after the TRIM notice is mailed. In practice that lands in mid-to-late September 2026, commonly cited around September 15 to 18. Do not guess: the exact deadline is printed on your TRIM notice. Circle it the day it arrives.

Miss that date and you generally forfeit your right to petition the Value Adjustment Board for the 2026 tax year.

The three values on your TRIM, and which one to fight

Florida TRIM notices list three different values, and confusing them is the number one mistake homeowners make.

• Just (market) value. This is the property appraiser's estimate of what your home would sell for on January 1, 2026. This is the number a petition challenges.
• Assessed value. For a homesteaded property, this is the just value after the Save Our Homes cap, which limits annual assessment increases to 3% or the change in CPI, whichever is lower.
• Taxable value. Assessed value minus your exemptions (homestead, senior, veteran, and so on). This is what your millage rate is actually applied to.

Because Save Our Homes can hold your assessed value well below market, a homesteaded owner sometimes sees a high just value but a much smaller taxable value. That does not mean you have no case. Under Florida Statutes §194.011, a petition challenges the just value. If the appraiser's just value is above what comparable homes actually sell for, that is your opening, and correcting it protects you in future years as the cap unwinds.

What to look for on your 2026 TRIM notice

Spend fifteen minutes with the notice and check four things:

1. Is the just value higher than recent comparable sales? Look up 3 to 5 similar homes near you that sold in the last 12 months. If they sold for less than your just value, you are likely over-assessed.
2. Did your just value jump more than the local market did? Mass-appraisal models apply broad neighborhood increases. If your number moved more than nearby sales justify, flag it.
3. Are all your exemptions applied? Confirm your homestead exemption is on the notice. Missing homestead, senior, widow/widower, disability, or veteran exemptions are common and worth challenging on their own.
4. Are the property details right? Wrong square footage, wrong bed/bath count, a pool that no longer exists, or condition problems the appraiser does not know about all inflate value.

Any one of these is a reason to act.

How to challenge it: informal review first

Before you file anything formal, call your county property appraiser's office and ask for an informal review or conference. Bring your comparable sales. Many Florida assessment disputes are resolved here without a petition, because the appraiser can correct an obvious error directly.

Do this early. The informal conference does not extend or replace your VAB petition deadline, so if August is ending and you have not reached an agreement, file the petition to preserve your rights and keep talking afterward.

How to file a DR-486 petition with the Value Adjustment Board

If the informal route does not fix it, you file a petition with your county's Value Adjustment Board (VAB), an independent body separate from the property appraiser. The mechanics:

• Form DR-486. This is the standard petition to the VAB for a reduction in assessed value. Your county VAB site has it, and most counties let you file online.
• Filing fee. Up to $15 per parcel, set by county.
• Deadline. Within 25 days of the TRIM mailing (§194.011(3)(d)), the date printed on your notice.
• Grounds. State that the just value exceeds market value. You can also petition over a denied exemption or classification using the related DR-486 series forms.

After you file, the VAB schedules a hearing before a special magistrate, an independent appraiser or attorney who hears both sides. You present your comparable sales and argument, the property appraiser presents theirs, and the magistrate recommends a value to the board.

The evidence that wins a Florida petition

Under Florida Statutes §194.301, the property appraiser's assessment gets a presumption of correctness, but that presumption can be overcome with competent, substantial evidence that the just value is wrong. What that means in practice:

• Comparable sales. 3 to 5 arm's-length sales of similar homes, similar in size, age, and location, sold close to January 1, 2026, for less than your just value. This is the core.
• Condition evidence. Photos and repair estimates for anything that reduces market value: roof, foundation, flooding history, dated systems.
• A clean one-page summary. Magistrates see stacks of these. A tidy comparable-sales table beats a stack of loose printouts.

The 2026 timeline at a glance

• Mid-to-late August 2026: TRIM notices mailed.
• August into September: request informal review, gather comps.
• 25 days after mailing (mid-to-late September 2026): VAB petition deadline. File DR-486.
• Fall through winter 2026-2027: special magistrate hearings.
• Tax bills mailed November 2026; a pending petition protects your right to a refund if the value is reduced.

Check before the deadline runs

The single biggest reason Florida homeowners overpay is not a weak case. It is missing the 25-day window because the TRIM notice looked like junk mail. When your 2026 TRIM arrives in August, do not file it away. Read it, compare your just value to real sales, and decide within the first week whether to act.

You can check whether your Florida property is over-assessed against comparable properties in about 30 seconds, free and with no signup, using our free calculator. If the comps show you are over the mark, you have the start of a DR-486 case.

Your TRIM notice is a 25-day invitation to lower your tax bill. Do not let it expire in a pile of mail.
