If you own a home in Pinellas County, you probably received a very official-looking piece of mail in August called a Notice of Proposed Property Taxes, commonly known as your TRIM Notice.
Before you file it away — or panic because you think it’s your tax bill — there are a few things worth checking.
First, your TRIM notice is NOT your property tax bill. Your actual tax bill comes from the Pinellas County Tax Collector around November 1.
What the TRIM notice does give you is an early look at your property’s value, exemptions, proposed tax rates, and estimated property taxes.
Here’s what I recommend homeowners look at.

1. CHECK YOUR HOMESTEAD EXEMPTION
Look at the exemptions listed on the notice and make sure the ones you expect to see are actually there.
This is particularly important if you purchased your home recently.
If you bought your home after January 1 and the TRIM notice shows a Homestead Exemption, keep in mind that the exemption may belong to the previous owner. Homestead Exemption doesn’t automatically transfer to you when you purchase a home.

BOUGHT YOUR HOME THIS YEAR?
The Homestead Exemption shown on your TRIM notice may actually belong to the previous owner.
2. UNDERSTAND THE THREE DIFFERENT “VALUES”
This is where homeowners often get confused.
Your home’s market value, assessed value, and taxable value can be three different numbers.
MARKET OR JUST VALUE
This is the Property Appraiser’s estimate of your property’s value as of January 1.
ASSESSED VALUE
This is the value after applicable assessment limitations, such as Save Our Homes for qualifying homesteaded properties, have been applied.
TAXABLE VALUE
This is generally your assessed value minus applicable exemptions. The taxing authorities apply their millage rates to taxable value to calculate your property taxes.
So, seeing a market value of $700,000 on your TRIM notice does NOT necessarily mean you’re being taxed on $700,000.

3. LOOK AT YOUR PROPOSED PROPERTY TAXES
Don’t stop at the property value.
Your TRIM notice also shows proposed tax rates and taxes from the different local taxing authorities.
An important distinction: the Property Appraiser determines property values but does not set your tax rates. Those rates are established by the individual taxing authorities.
Your notice also provides information about their public budget hearings.
So, if you’re trying to understand why your proposed taxes changed, look at both your property values and the proposed rates.
4. RECENTLY BOUGHT YOUR HOME? PAY EXTRA ATTENTION.
This is probably one of the biggest surprises I see with newer Florida homeowners.
A seller may have owned a home for many years and benefited from Florida’s Save Our Homes assessment limitation. Their assessed value — and therefore their property taxes — could be substantially lower than the home’s current market value.
When that property changes ownership, the previous owner’s Homestead Exemption and Save Our Homes benefit don’t simply transfer to the buyer. A change in ownership generally resets the capped assessed value to market value for the following year.
That’s why looking at what the previous owner paid in property taxes isn’t necessarily a good way to estimate what youwill pay after purchasing the home.
It’s also one of the reasons I caution buyers against assuming the property taxes shown on a real estate listing will be their future tax bill.

5. YOUR TRIM VALUE ISN’T NECESSARILY WHAT YOUR HOME WOULD SELL FOR TODAY
This is one of the biggest misconceptions I hear.
The Property Appraiser’s market value is based on the property’s value as of January 1.
But the real estate market doesn’t freeze on January 1.
Homes continue to sell. Inventory changes. Buyer demand changes. Renovations, condition, location within a neighborhood, lot, view, flood zone, and dozens of other factors can affect what a buyer would actually pay for a particular home.
So, while the Property Appraiser’s market value serves an important purpose for taxation, it isn’t necessarily the same as what your home would sell for in the current market.
If you’re looking at your TRIM notice and wondering whether the value makes sense compared with what homes are actually selling for in your neighborhood, send it to me. I’m always happy to take a look.
WHAT IF SOMETHING LOOKS WRONG?
Start by contacting the Pinellas County Property Appraiser’s Office.
If you disagree with the proposed value, the Property Appraiser actually encourages homeowners to speak with the area appraiser listed on their TRIM notice.
If the issue involves an exemption, their office can also help determine whether an exemption is missing or incorrect.
There is also a formal process through the Value Adjustment Board (VAB) for challenging certain property value and exemption decisions.
READING THIS AFTER THE 2026 DEADLINE?
For the 2026 TRIM cycle, September 11, 2026 was the deadline to file a Value Adjustment Board petition or late-file for Homestead Exemption.
If you’re reading this after that date and something looks wrong, I still wouldn’t ignore it.
Contact the Pinellas County Property Appraiser’s Office directly, explain the issue, and ask what options may still be available based on your particular circumstances.
THE BOTTOM LINE
Your TRIM notice isn’t exactly exciting reading, but it’s one piece of mail Florida homeowners shouldn’t automatically toss into a pile.
Take five minutes and check:
• Your exemptions
• Your market, assessed, and taxable values
• Your proposed taxes
• Whether anything looks substantially different from what you expected
And if it’s the market value that has you scratching your head, that’s where I can help.
I spend every day looking at what buyers are actually paying for homes throughout Palm Harbor, Dunedin, Safety Harbor, Tarpon Springs, Clearwater, and Tampa and the surrounding counties.
If you’d like to know how your TRIM value compares with your home’s current real-world market value, reach out. I’m happy to pull the recent neighborhood sales and give you some context — no sales pitch attached.
