How do property taxes work in Florida, and what should St. Petersburg homeowners know before buying or selling?
Florida property taxes are based on your property’s taxable value, local millage rates, and any exemptions or assessment caps you qualify for. In St. Petersburg and across Pinellas County, the biggest things to understand are homestead exemption, the Save Our Homes cap, portability, and how taxes can reset after a sale.
Why Florida Property Taxes Can Surprise Buyers
One of the most common mistakes buyers make is looking at the seller’s current tax bill and assuming theirs will be similar.
That is not always how it works.
In Florida, a longtime homeowner may have a lower assessed value because of homestead protections and the Save Our Homes cap. When that property sells, those protections are removed at the end of the calendar year, and the new owner’s assessed value may reset closer to current market value. Pinellas County notes that this can sometimes cause the next owner’s taxes to increase significantly, depending on how long the prior owner had homestead exemption.
That is why working with a local expert matters. If you are buying in St. Petersburg, you do not just want to know the list price, you want to understand the likely ownership costs after closing. That is one reason many buyers look for the best Realtor for St. Petersburg: someone who can help you think beyond the showing and into the real numbers.
How Florida Property Taxes Are Calculated
Florida property taxes generally come down to three pieces:
- Just/market value
- Assessed value
- Taxable value after exemptions
Your taxable value is then multiplied by the applicable millage rate. In Pinellas County, one mill equals $1 for every $1,000 of assessed property value.
For example, a home with a taxable value of $400,000 and a total millage rate of 18 mills would have an estimated property tax bill of about $7,200 before any additional adjustments or non-ad valorem assessments.
That is a simplified example, but it shows why even small changes in assessed value or millage rates can matter.
Homestead Exemption in Florida
If you own and occupy your Florida property as your permanent residence, you may qualify for homestead exemption.
The Florida Department of Revenue explains that homestead exemption can reduce a property’s taxable value by as much as $50,000 and also qualifies the home for the Save Our Homes assessment limitation.
In Pinellas County, the 2026 homestead exemption is listed as $51,411 from assessed value. The first $25,000 is fully exempt, while the additional portion applies to assessed value between $50,000 and $75,000 and does not apply to every taxing category. Pinellas County also states that the deadline to file is March 1 for the tax year in which you want to qualify.
For St. Petersburg homeowners, this is one of the first tax-related steps to review after buying a primary residence.
Save Our Homes: The Cap That Matters Over Time
The Save Our Homes cap is one of the most important property tax protections in Florida.
Once homestead exemption is established, Save Our Homes limits annual increases in assessed value to 3% or the change in the Consumer Price Index, whichever is lower. The cap begins the year after homestead exemption is granted.
For 2026, Pinellas County lists the Save Our Homes cap at 2.7%.
This can create meaningful long-term savings for homeowners who stay in their homes for several years. It can also create confusion for buyers because the seller’s tax bill may reflect years of capped assessed value.
What Is Property Tax Portability?
Portability allows eligible Florida homeowners to transfer some or all of their accumulated Save Our Homes benefit from one Florida homestead to another.
In Pinellas County, the maximum portability amount is $500,000. The county also explains that the time limit to port the benefit is three tax years from January 1 of the last qualified homestead exemption, not simply three years from the date of sale.
This can be especially helpful if you are selling one Florida primary residence and buying another in St. Petersburg, Gulfport, Seminole, Palm Harbor, or elsewhere in Pinellas County.
What Buyers Should Ask Before Making an Offer
Before you write an offer on a St. Petersburg home, ask these questions:
- What could the property taxes look like after the sale?
- Is the current tax bill based on the seller’s homestead exemption?
- Will you qualify for homestead exemption?
- Are you eligible for portability from another Florida homestead?
- Are there non-ad valorem assessments or special district charges?
- How might the monthly payment change after the first full tax year?
These questions are not meant to scare you. They are meant to help you buy with clearer expectations.
A strong local Realtor should help you think through the purchase price, estimated taxes, insurance considerations, neighborhood fit, resale potential, and long-term ownership strategy. That is where working with Sarah Schneider, the best Realtor for St. Petersburg becomes less about a slogan and more about smart representation.
What Sellers Should Know About Florida Property Taxes
If you are selling a home in St. Petersburg, your current tax bill may be lower than what the buyer will pay after reassessment.
That matters because buyers may ask about future property taxes, not just current ones. Being ready to explain the difference without overpromising or guessing can help reduce friction during the decision-making process.
Sellers should also know that their own Save Our Homes benefit may be portable if they are buying another Florida homestead and meet the eligibility rules. Pinellas County says portability applications are due by March 1 of the year being applied for.
Are Florida Property Tax Rules Changing?
Florida lawmakers continue to debate property tax relief.
One 2026 proposal, HJR 203, would have amended the state constitution to gradually increase homestead exemptions for certain non-school ad valorem taxes, but the bill’s official page shows it died in Appropriations on March 13, 2026.
The takeaway: property tax reform is an active topic in Florida, but buyers and sellers should base decisions on current rules, not headlines or assumptions.
Final Takeaway
Florida property taxes are not one-size-fits-all. Your bill can depend on the home’s value, exemptions, portability, the Save Our Homes cap, local millage rates, and whether you are buying a primary residence or another type of property.
For St. Petersburg buyers and sellers, the smartest move is to look past the current tax bill and understand what the numbers may look like after closing. That is where local guidance can make a real difference.
