Understanding Your TRIM Notice

TRIM = Truth in Millage (your official assessment)

What to Look For:

1. Market Value: What county thinks it's worth
2. Assessed Value: After exemptions
3. Taxable Value: What you're taxed on
4. Save Our Homes Cap: Your protection
5. Exemptions Applied: Homestead, senior, etc.

The Miami-Dade Twist:

• Values in English and Spanish
• Multiple taxing authorities
• Special districts common
• Non-ad valorem assessments

Step 2: Evidence Exchange

• Submit with petition or later
• County provides their evidence
• You can respond
• No surprises at hearing

Step 3: Hearing Options

• Informal setting
• 15-30 minutes typical
• Recommendation to VAB

Option B: VAB Direct

• Final decision

Most choose magistrate - more favorable

The Bottom Line

Miami-Dade's unique market dynamics - foreign investment, climate risks, building issues - create both assessment challenges and appeal opportunities.

Success requires understanding local factors: your municipality matters, building condition is crucial, and hurricane history affects value. With proper evidence and professional presentation, VAB magistrates are reasonable.

Don't let Miami-Dade's complexity discourage you. The 25-day deadline is tight, but the savings last forever.

In Miami-Dade County, where property values swing wildly and climate change is reality not theory, accurate assessment isn't just about fair taxation — it's about recognizing true market value in a unique, challenging environment.
