How to Read Your Miami-Dade TRIM Notice Without Panicking

 

 

If you just opened your Miami-Dade TRIM notice and the numbers made you nervous, start with the most important fact:

Your TRIM notice is not a property tax bill.

It is the annual Notice of Proposed Property Taxes sent by the Miami-Dade County Property Appraiser. It shows your property's values and exemptions, proposed tax rates and taxes, non-ad valorem assessments, and information about upcoming taxing-authority budget hearings.

Miami-Dade mails TRIM notices to property owners by August 24. The actual property tax bill is generally mailed in November.

That does not mean you should ignore the notice.

August is actually one of the most important times of the year to check that your property information, exemptions, and assessed value appear correct, because some review and appeal deadlines are time-sensitive.

What Does TRIM Mean?

TRIM stands for Truth in Millage.

Florida's Truth in Millage process is designed to show property owners which taxing authorities are proposing taxes and millage rates before those rates and budgets become final. It also gives taxpayers information about public budget hearings.

In plain language, your TRIM notice is a preview.

It tells you:

• What Miami-Dade currently says your property is worth for tax purposes
• Which exemptions and assessment benefits are being applied
• Which taxing authorities are charging taxes
• Their proposed tax rates
• Approximately what those taxes would produce
• Certain non-ad valorem assessments
• When taxing authorities will hold budget hearings

Think of the TRIM notice as an annual property-tax checkup, not an invoice.

What Should You Look at First?

You do not need to understand every line immediately.

Start with these five areas:

What to Check	Why It Matters
Market or just value	Shows the Property Appraiser's estimate of your property's value
Assessed value	Reflects applicable assessment limitations such as Save Our Homes
Exemptions	Confirms benefits such as Homestead are being applied
Taxable value	This is the value used by taxing authorities to calculate ad valorem taxes
Proposed taxes and assessments	Shows what different authorities may charge and any listed non-ad valorem assessments

Then compare those items with last year's notice.

A change does not automatically mean something is wrong. The goal is to understand what changed and why.

What Is Market Value on a Miami-Dade TRIM Notice?

The Property Appraiser may refer to this as market value or just value.

It represents the Property Appraiser's estimate of the property's value for assessment purposes.

Miami-Dade uses recognized valuation approaches, including market, cost, and income methods depending on the property.

This number is not necessarily:

• Your asking price
• What Zillow says your home is worth
• What a buyer would offer tomorrow
• Your mortgage appraisal
• A Realtor's comparative market analysis

Those figures serve different purposes.

Your TRIM market value is a property-tax valuation, not a promise of what your home would sell for.

If you are trying to understand what your home might actually sell for, see how much your Miami home is worth.

What Is Assessed Value?

Your assessed value is the value after applicable assessment limitations are considered.

For many longtime Miami-Dade homeowners, this number is lower than market value because of Florida's Save Our Homes benefit.

Save Our Homes limits annual increases in the assessed value of qualifying homestead property to 3% or the Consumer Price Index, whichever is lower.

For the 2026 tax year, Miami-Dade's current tax comparison system reflects a 2.70% Save Our Homes assessment limitation for qualifying homestead property.

That cap applies to the assessed value, not necessarily to the final tax bill.

This distinction matters.

Save Our Homes limits assessment growth. It does not guarantee that your total property taxes can never increase by more than that percentage.

Tax rates, exemptions, non-ad valorem assessments, property changes, and other factors can also affect the final amount.

What Is Taxable Value?

Taxable value is the amount to which a particular taxing authority applies its tax rate.

A simplified way to think about it is:

Market value → assessment limitations → assessed value → exemptions → taxable value

But the taxable value may differ between taxing authorities because not every exemption applies equally to every authority.

Miami-Dade's TRIM guidance specifically notes that taxable values can vary by taxing authority because some exemptions do not apply to all authorities.

That is why you may see several taxable-value figures instead of one universal number.

What Is the Homestead Exemption?

Florida's Homestead Exemption provides property-tax benefits to qualifying owners who make the property their permanent residence and meet the applicable requirements.

Miami-Dade homeowners should check the exemptions section of their TRIM notice carefully to confirm that the Homestead Exemption and any other benefits they expect are actually listed.

Do not assume that because Homestead appeared last year, every detail on this year's notice must be correct.

Look for:

• Homestead Exemption
• Senior exemptions, if applicable
• Disability or veteran exemptions, if applicable
• Portability benefits, when applicable
• Other exemptions for which you qualified

If an expected exemption is missing, contact the Miami-Dade Property Appraiser promptly.

What Is Save Our Homes?

Save Our Homes, often abbreviated SOH, is an assessment limitation tied to qualifying Florida homestead property.

Once the benefit applies, annual increases in assessed value are generally limited to 3% or the Consumer Price Index, whichever is lower.

Over many years, this can create a significant difference between:

Market value and assessed value

Miami-Dade calls that accumulated difference the Save Our Homes benefit.

For example, a longtime homeowner might have:

• Market value: $650,000
• Assessed value: $410,000

That does not mean the home is worth only $410,000. It means assessment limitations have kept the taxable assessment below current market value.

Why Should You Verify Homestead and Save Our Homes?

Because these benefits can materially affect your property taxes.

If you expect Homestead and Save Our Homes to apply, check your notice rather than assuming everything carried forward correctly.

This is especially important after:

• A purchase
• A transfer of title
• Marriage or divorce
• A move
• Changes in ownership
• Applying for portability
• Adding or removing an owner
• Changes in how the property is used

Miami-Dade specifically encourages homeowners to review their August TRIM notice to confirm exemption changes.

If something does not look right, contact the Property Appraiser rather than waiting for the November tax bill.

Why Are There So Many Different Taxing Authorities?

Your property tax is not created by one single agency.

Different taxing authorities use the taxable value established by the Property Appraiser and apply their own proposed millage rates.

Depending on where your property is located, your TRIM notice may include taxes associated with entities such as:

• Miami-Dade County
• Miami-Dade County Public Schools
• Your city or municipality
• The Children's Trust
• Other special or regional taxing authorities

The Property Appraiser determines property values and exemptions, but does not set the millage rates and does not collect your property taxes.

That distinction matters if you disagree with the amount.

If the issue is your property value or exemption, the Property Appraiser is the appropriate starting point.

If the issue is a proposed millage rate, the taxing authority is responsible for that rate.

The Miami-Dade Value Adjustment Board cannot reduce a millage rate simply because a homeowner believes the resulting tax is too high.

What Are Non-Ad Valorem Assessments?

Not every charge on your property-tax notice is based on property value.

Miami-Dade describes non-ad valorem assessments as special assessments or service charges that are not calculated from your property's value.

These may pay for services such as:

• Garbage collection
• Lighting
• Security
• Landscaping
• Special districts
• Certain infrastructure

Because they are not based on your property's taxable value, lowering a property valuation does not necessarily reduce these charges.

What Is a CDD Assessment?

Some Miami-Dade properties are located within a Community Development District, or CDD.

A CDD is a special-purpose local governmental district used to finance and manage infrastructure or community improvements. These can include roads, utilities, water systems, parks, clubhouses, and other infrastructure.

CDD charges are generally treated as non-ad valorem assessments, meaning they are not calculated from the property's market value.

Depending on the property, a CDD assessment may appear on the August TRIM notice and later on the November tax bill.

If your proposed total looks unusually high, check the non-ad valorem section rather than assuming the entire increase came from property value or millage.

A CDD charge can increase your total property-tax bill even though it is not an ad valorem property tax.

Why Might My Proposed Taxes Be Higher Than Last Year?

There are several possible reasons.

Your taxable value increased

This could result from normal assessment changes, new construction, improvements, or a reassessment following a change in ownership.

A taxing authority changed its proposed millage rate

Your assessed value can remain relatively stable while a proposed tax rate changes.

Your exemption changed

A missing, reduced, or changed exemption can affect taxable value.

You recently purchased the property

This is one of the most important situations to understand.

A non-ad valorem assessment changed

Garbage, special district, CDD, or other assessments can change independently of the property's value.

Your property was improved

Certain improvements or additions may affect assessed value.

A higher number deserves an explanation, but it does not automatically mean an error was made.

And if you are considering selling, property taxes are only one part of the picture, so it also helps to understand the hidden costs Florida homeowners forget before selling. 

What Should New Miami-Dade Homeowners Pay Special Attention To?

New homeowners should be particularly careful when comparing their taxes with what the previous owner paid.

Florida law specifically warns buyers not to rely on the seller's current property taxes as an estimate of what the buyer will owe after the purchase. A change of ownership can trigger reassessment.

That potential tax change is also one reason buyers should look beyond the purchase price when calculating the true cost of buying a home in Miami.

Miami-Dade explains that if you purchase after January 1, you may temporarily inherit the seller's Homestead Exemption and assessment limitation for that tax year.

The following year, however, the previous owner's exemption and Save Our Homes limitation are removed. The property can then be reassessed at market value before the new owner's qualifying benefits are applied.

This is why a new owner can receive a TRIM notice that looks dramatically different from the seller's previous tax history.

It does not necessarily mean the county made an error.

If the property is your permanent residence and you qualify, make sure you filed for your own Homestead Exemption by the applicable deadline.

The seller's property-tax history belongs to the seller's ownership situation. It does not automatically transfer to the buyer.

What If I Think Miami-Dade's Property Value Is Too High?

Start by reviewing the property information used by the Miami-Dade Property Appraiser.

Ask yourself:

• Is the square footage correct?
• Is the property type correct?
• Are the bedroom and bathroom counts accurate?
• Are improvements being attributed correctly?
• Are there factual errors?
• Does the valuation appear inconsistent with relevant market evidence?
• Are the exemptions correct?

Miami-Dade encourages property owners who disagree with an assessment to contact the Property Appraiser and request an informal review.

If the issue cannot be resolved, a property owner may have the option to petition the Miami-Dade County Value Adjustment Board, or VAB.

For the 2026 tax year, the deadline to file a timely Miami-Dade VAB petition is September 18, 2026.

The deadline is important.

Do not assume that calling the Property Appraiser automatically extends the time to file a VAB petition.

What Can the Value Adjustment Board Review?

The VAB can hear certain disputes involving:

• Market or assessed value
• Denied exemptions
• Certain classifications
• Portability and other qualifying issues

The VAB does not have authority to reduce a taxing authority's millage rate merely because the resulting tax amount feels too high.

For 2026, a standard VAB petition generally carries a $15 filing fee per folio, subject to exceptions for certain petition types.

Because appeal rights and procedures are time-sensitive, rely on the Miami-Dade Property Appraiser and Miami-Dade Clerk of the Court and Comptroller for current instructions.

What Should I Do When My TRIM Notice Arrives?

Here is the simple process I recommend.

Step 1: Do not treat it as a bill

The actual tax bill comes later.

Step 2: Confirm the property information

Check the owner name, property address, folio, and basic characteristics.

Step 3: Compare market and assessed value

Look at this year versus last year.

Ask why each changed.

Step 4: Verify your exemptions

Make sure Homestead and any other expected exemptions appear correctly.

Step 5: Check Save Our Homes

If you are an established homestead owner, review the assessed-value change and make sure the benefit appears consistent with your situation.

Step 6: Review each taxing authority

Determine whether an increase comes from value, tax rates, or both.

Step 7: Look at non-ad valorem charges

Check for garbage, special district, CDD, or other assessments.

Step 8: Pay extra attention if you bought recently

Do not compare your future tax obligation directly with the seller's old tax bill.

Step 9: Ask questions quickly if something looks wrong

Contact the Miami-Dade Property Appraiser.

Step 10: Watch the deadline

For tax year 2026, the Miami-Dade VAB petition deadline is September 18, 2026.

Do not put the notice in a drawer if something looks incorrect. TRIM season is the time to investigate.

A Simple TRIM Notice Checklist

When your notice arrives, check:

• Property address and folio
• Market value
• Assessed value
• Taxable value
• Homestead Exemption
• Save Our Homes benefit
• Other exemptions
• Proposed millage rates
• Proposed taxes by taxing authority
• Non-ad valorem assessments
• Any CDD assessment
• Public hearing dates
• VAB filing deadline
• Changes compared with last year

If you understand why each major number changed, the notice becomes much less intimidating.

Can I Help You Understand Your TRIM Notice?

Yes, with an important limitation.

I am a Realtor, not a tax professional or attorney, and I cannot determine your tax liability, give tax advice, or advise you on a legal appeal.

But I do work with Miami-Dade property records regularly.

If your TRIM notice arrives and something looks confusing, incorrect, or simply much higher than you expected, you are welcome to send me a clear photo or screenshot. For privacy, feel free to cover personal information you do not want to share.

I can help you identify what section you are looking at, compare it with publicly available property information, and point you toward the appropriate Miami-Dade Property Appraiser, Value Adjustment Board, tax professional, attorney, or other official resource when something deserves closer attention.

There is no pressure and no obligation.

Sometimes the most useful first step is simply understanding which number is causing the concern and who can answer the question.

The Bottom Line

Your Miami-Dade TRIM notice is not a tax bill.

It is your annual opportunity to review the county's property valuation, assessed value, exemptions, proposed taxes, taxing authorities, and certain non-ad valorem assessments before the final tax bill arrives.

Pay particular attention to:

1. Market value
2. Assessed value
3. Taxable value
4. Homestead Exemption
5. Save Our Homes
6. Proposed tax rates
7. Non-ad valorem and CDD assessments
8. Changes following a recent purchase

A higher proposed amount does not automatically mean something is wrong.

But if something is wrong, August and September are important months to address it.

For 2026, Miami-Dade's timely VAB petition deadline is September 18, 2026, so homeowners with valuation or exemption concerns should review their notice promptly and use the official county resources for formal guidance.

Frequently Asked Questions

Is the Miami-Dade TRIM notice a property tax bill?

No. The TRIM notice is the Notice of Proposed Property Taxes. Miami-Dade states clearly that it is not a bill. The final property tax bill is generally mailed in November.

What does TRIM stand for?

TRIM stands for Truth in Millage. Florida's TRIM process informs property owners about proposed property taxes, millage rates, and public budget hearings before rates become final.

When does Miami-Dade send TRIM notices?

Miami-Dade mails TRIM notices to property owners by August 24 each year.

What is the difference between market value and assessed value?

Market value is the Property Appraiser's valuation of the property. Assessed value reflects applicable assessment limitations such as Save Our Homes.

What is taxable value?

Taxable value is the amount to which a taxing authority applies its millage rate after applicable assessment limitations and exemptions are considered.

What should I do if my Homestead Exemption is missing?

Contact the Miami-Dade Property Appraiser promptly. Exemption and appeal procedures have deadlines, so do not wait until the November tax bill arrives.

What is Save Our Homes?

Save Our Homes limits annual increases in the assessed value of qualifying homestead property to 3% or the CPI, whichever is lower. The 2026 Miami-Dade cap reflected in the Property Appraiser's system is 2.70%.

Why are my property taxes higher after buying a home?

A change in ownership may reset the property's assessed value. The seller's Homestead Exemption and Save Our Homes benefit generally do not become the buyer's permanent benefits.

What is a CDD charge?

A Community Development District charge is generally a non-ad valorem assessment used to fund infrastructure or services within a district. It may appear on the TRIM notice and later on the property tax bill.

Can I appeal my Miami-Dade property value?

Property owners can first request an informal review with the Property Appraiser. If the issue is not resolved, eligible disputes may be brought to the Value Adjustment Board.

What is the Miami-Dade VAB deadline for 2026?

The deadline for a timely 2026 Value Adjustment Board petition is September 18, 2026.

Can the Value Adjustment Board lower my tax rate?

No. The VAB can address certain valuation, exemption, classification, and related disputes, but it cannot change a taxing authority's millage rate.
