Florida TRIM Notice Explained

1 Verify Your Property Owner Information

The first section shows your name, mailing address, and property address. This might seem basic, but errors here can cost you money and create legal issues.

Common Issues to Check:

• • Deceased spouse still listed as owner
• • Missing spouse who should be on the deed
• • Incorrect mailing address (you'll miss important notices)
• • Misspelled names that don't match your deed

If you need to add your spouse to the deed for maximum exemptions, consider an enhanced life estate deed. For recently married couples, learn how to add your spouse to the deed. If you're divorced or widowed, you may need to remove a spouse from the deed.

Action Item: Contact your property appraiser's office immediately if any information is incorrect. Deed changes may require legal assistance.

2 Understanding Millage Rates: What You're Actually Paying

Millage rates are how your tax is calculated. One mill equals $1 of tax for every $1,000 of taxable value, as explained in the Florida Department of Revenue's millage guide. Your TRIM notice shows separate rates for county, city, school district, and special districts.

Typical Florida Millage Breakdown:

• • School District: 6-8 mills (often the largest portion)
• • County: 4-6 mills
• • City: 2-4 mills (if you live in a city)
• • Special Districts: 0.5-2 mills (fire, water, etc.)

Important: School taxes are calculated on your full assessed value because most exemptions don't apply to school millage. This is why school taxes often represent 40-50% of your total bill, even though recent legislative efforts aim to reduce this burden.

Your Rights: You can attend public hearings to challenge proposed millage rate increases. Dates and times are listed on your TRIM notice.

3 How Your Property's Market Value is Determined

Your property's market value is assessed as of January 1st each year. Property appraisers use comparable sales, replacement cost, and income approaches to determine what your property would sell for in the current market.

Assessment Methods:

• • Sales Comparison: Recent sales of similar nearby properties
• • Cost Approach: Replacement cost minus depreciation
• • Income Approach: For rental properties only

If your market value seems too high, you have the right to appeal. The Value Adjustment Board (VAB) process allows you to challenge your assessment, but you must file within 25 days of receiving your TRIM notice. Learn the complete appeal process here.

Time-Sensitive: You only have 25 days from the TRIM notice date to file an appeal. There's typically a $15 filing fee, waived if your property value is under $100,000.

4 Save Our Homes: Your 3% Annual Increase Cap

Save Our Homes (SOH) is Florida's constitutional protection that limits annual increases in your homestead property's assessed value to 3% or the inflation rate, whichever is lower. Originally passed in 1992 as Amendment 10, this landmark constitutional amendment creates a significant difference between market value and assessed value for longtime homeowners.

How Save Our Homes Saves You Money:

The assessed value is what most of your taxes are calculated on (except school taxes). If you move, you can transfer some of this tax savings to a new Florida home through Save Our Homes portability—voters extended the portability window to three years in 2020. Calculate your portability savings here.

Important: Save Our Homes only applies to homestead properties. Investment properties don't receive this protection.

5 Exemptions You Have (And Ones You're Missing)

This section lists all exemptions currently applied to your property. Exemptions directly reduce your taxable value, which means immediate tax savings. Many Florida homeowners are missing exemptions they qualify for.

Missing Exemptions Checklist:

• • Homestead Exemption: $50,722 off assessed value (first $25k off all taxes, next $25,722 off non-school taxes)
• • Senior Exemption: Additional exemption for homeowners 65+ with income limits
• • Veteran Exemptions: Various exemptions for military service
• • Disability Exemptions: For qualifying disabilities
• • Additional Homestead: Extra exemption for seniors with income limits

If you don't see the homestead exemption listed, you're missing significant savings. You can download the official DR-501 homestead application form or learn how to apply for homestead exemption. Seniors should also check if they qualify for additional senior exemptions.

Quick Check: Use our free exemption calculator to see which exemptions you might be missing and estimate your potential savings.

6 From Taxable Value to Your Tax Bill

This is where everything comes together. Your taxable value is your assessed value minus exemptions. This final number is multiplied by the millage rates to calculate your actual tax bill.

The Math:

Remember that school taxes are calculated differently—they use your full assessed value (minus only homestead exemption) because most other exemptions don't apply to school millage.

Payment Options: Property taxes are typically due by March 31st, but most counties offer discount for early payment (up to 4% discount if paid in November).

7 How to Challenge Your Assessment or Millage Rates

Your TRIM notice includes information about public hearings where you can challenge proposed millage rate increases. You also have the right to appeal your property's assessed value through the Value Adjustment Board (VAB) process—the Florida DOR's PT-101 guide explains the complete petition process.
