Tampa property tax: how a Hillsborough County bill is built

How a Tampa property tax bill is calculated

The Florida Department of Revenue reduces the whole system to three lines: assessed value equals just value minus assessment limits; taxable value equals assessed value minus exemptions; and the tax equals taxable value times the millage rate. Each step has its own office and its own date.

One detail confuses many owners: a homestead has two taxable values. The Property Appraiser's 2026 TRIM guide explains that the first $25,000 of the homestead exemption applies to every levy, while the additional homestead exemption does not apply to school taxes. So the school line is figured on a higher taxable value than the county and city lines. Who qualifies and the 2026 amounts are in Florida homestead exemption requirements.

Hillsborough County property tax rates by district: 2025 final millage

Where the home sits decides which levies apply. The Property Appraiser publishes the final millage for four main tax districts. The latest table on its Truth in Millage page, as of late October 2026, is for the 2025 tax year, the bills mailed in November 2025.

Because the 6.3400 school mills apply to the higher school taxable value, you cannot multiply one taxable value by the total. City homes pay a city operating levy, while unincorporated homes pay the county MSTU instead, so compare the district for each address you are considering. The where to downsize pages describe the areas themselves.

For 2026, each taxing authority proposed a rate on the August TRIM notice and adopted a final rate after public hearings; those rates are printed on the November 2026 bill. Some parcels also carry non-ad valorem assessments, which the Tax Collector describes as charges based on the benefit to specific parcels, set by the local governing board rather than by millage.

A hypothetical Tampa property tax bill, step by step

Every figure in this section is hypothetical. It applies the 2025 final City of Tampa millage above and the 2025 homestead exemption amounts: $25,000 against all levies plus an additional $25,722 against non-school levies, the 2025 figure the Department of Revenue lists. It leaves out non-ad valorem assessments and any other exemption. Your own bill will use the year's actual rates and your values.

Take a house inside the City of Tampa with a homestead exemption and an assessed value of $300,000:

• School taxable value: $300,000 minus $25,000 = $275,000. At 6.3400 mills: $275,000 ÷ 1,000 × 6.3400 = $1,743.50
• Non-school taxable value: $300,000 minus $25,000 minus $25,722 = $249,278. All other City of Tampa levies total 13.5028 mills: $249,278 ÷ 1,000 × 13.5028 = $3,365.95
• Total ad valorem tax: $5,109.45. Paid in November with the 4 percent discount, it would be $4,905.07.

Now the downsizing question. Suppose the same house has a just value of $600,000, the owner sells and buys a City of Tampa condo with a just value of $360,000. The portability formula in our homestead portability guide gives the condo an assessed value of $180,000 in that case. Here is what each version of the bill looks like at 2025 rates:

The spread is the point. A smaller home can cost more in tax than the larger one it replaces if the owner does not file for homestead and portability, and the seller's current bill tells a buyer almost nothing. The portability and net proceeds calculator runs the assessed-value part with your own figures.

Using a Florida property tax calculator for a Hillsborough home

Many online Florida property tax calculators apply one average rate to a price. That misses the district, the split between school and non-school taxable value, the reset after a sale and any portability you bring. The 2026 TRIM guide tells buyers to use the Property Appraiser's online tools, including its tax estimator, before purchasing. Or do the arithmetic yourself with the steps above. Either way, treat the result as a planning number: the Property Appraiser sets just value, which is not necessarily the price you pay, and rates change every year.

The Hillsborough TRIM notice: what to check in August

The Notice of Proposed Property Taxes, known as the TRIM (Truth in Millage) notice, should reach every owner by the end of August, according to the Property Appraiser. It is not a bill. The Property Appraiser's 2026 guide walks through each part, and four of them deserve a close read:

• The value information. Market value, assessment reductions, assessed value, exemptions and taxable value, shown separately for county, school, municipal and other levies. Check that each exemption you applied for is listed.
• Last year's taxable value and final taxes. A comparison point, not your current tax.
• Taxes if no budget change is made next to taxes if the proposed budget change is made. The gap shows how much of the change comes from proposed budgets rather than your value.
• The public hearing notice. Taxing authorities hold hearings before they adopt final budgets and rates. That is where to speak about a rate. The Value Adjustment Board, the guide notes, does not set millage.

If you think the value is wrong, call the Property Appraiser first at (813) 272-6100 or use its value review form; the office says owners can expect to be contacted within 3 to 5 business days. If that does not resolve it, you may petition the Value Adjustment Board. The Property Appraiser's important dates page gives 25 days from the mailing of the TRIM notice, and the exact deadline is printed on the notice. In a value dispute, the issue is market value as of January 1, so sales before that date are the useful evidence.

Why a homestead bill rises when the market is flat

The Save Our Homes page of the Property Appraiser answers this directly. Under the recapture rule, adopted by the Department of Revenue in 1995, the assessed value of a homestead that sits below full market value is raised each year by the lower of 3 percent or the change in the Consumer Price Index. So a long-time owner's assessed value keeps climbing toward market value even in a year when prices stand still. Section 193.155 also says the assessed value can never exceed just value; if the market falls far enough, the assessed value is lowered to match.

A bill can also move because a taxing authority changes its millage, a non-ad valorem assessment changes or you add on. The Property Appraiser says new construction and additions are assessed at full market value on the first January 1 after they are substantially completed, then fall under the cap.

Hillsborough County property tax due dates and discounts

Under section 197.333, taxes are due and payable on November 1, or as soon after as the certified roll reaches the Tax Collector, and become delinquent on April 1 of the following year. Section 197.162 sets the early-payment discount: 4 percent in November, 3 percent in December, 2 percent in January, 1 percent in February and none in March. If a discount period ends on a weekend or legal holiday, it extends to the next working day for payments delivered to the Tax Collector's office. The Tax Collector's installment plan, with an April application deadline, is summarized in our seniors guide linked below. If you are juggling two homes, know what an unpaid bill sets off:

• The Tax Collector adds 3 percent interest and advertising costs once taxes are delinquent, and publishes the delinquent list in May.
• A tax certificate is then sold on the parcel at an online auction, with interest of up to 18 percent accruing from June 1. The certificate is a first lien.
• A tax deed foreclosure can begin two years after the taxes become delinquent. The Tax Collector does not accept partial payments on delinquent real estate taxes.

Section 197.122 makes taxes a first lien on the property from January 1 of the year they are levied. That is why a closing settles the current year's taxes between seller and buyer even though the bill comes in November.

Escrow and paid-off mortgages

If your lender pays your taxes from escrow, the Tax Collector says mortgage and loan servicers send it a list of the accounts they will pay each year. When you pay off the mortgage, as many downsizers do at closing, the lender should remove the parcel from that list and the bill then comes to you. The Tax Collector says tax information is available on its website on or after November 1. If a bill on a home you just bought still shows the prior owner's name, the Tax Collector notes that the name of record does not prevent payment.

What resets when you sell and buy in Hillsborough County

• The old home's cap ends. The Property Appraiser says the Save Our Homes limitation, like the exemption, expires on January 1 of the year after a change of ownership, and the home is raised to full market value. The same rule is why your new home will not inherit its seller's bill.
• The new home starts at just value. Section 193.155(3) assesses a homestead at just value as of January 1 of the year after a change of ownership. The 2026 TRIM guide warns new owners that taxes may be much higher than the prior owner's.
• The exemption must be filed again, with title and permanent residence on January 1 and an application by March 1.
• Part of the cap can move. Portability carries a share of your Save Our Homes benefit, up to $500,000, to a new Florida homestead; the formula and forms are in the portability guide.
• Senior exemptions start over. The income-limited senior exemption must be applied for again, and the long-term residency version needs 25 years in the home. See property tax exemptions for seniors, which also covers the installment plan.

If you keep the old house

Some owners rent out the old house or hold it while they decide. Without a homestead exemption it becomes non-homestead residential property under section 193.1554, if it has nine or fewer units. Its assessed value can then rise up to 10 percent a year, and that cap does not apply to school levies. The Property Appraiser also says renting out a homestead would likely forfeit the exemption. Our snowbird Florida guide covers the second-home side, and buying first or selling first covers the timing around January 1.

A Tampa property tax calendar for the year you move

• January 1: the assessment date. Ownership and permanent residence on this date decide that year's homestead.
• March 1: deadline for homestead, portability and other exemption applications with the Property Appraiser.
• Last day of April: deadline to apply for the Tax Collector's installment plan for the year.
• By the end of August: the TRIM notice arrives. Check values and exemptions, and note the Value Adjustment Board deadline printed on it.
• October: the Property Appraiser lists this as the month the assessment roll is certified for collection.
• November: the Tax Collector mails bills. Paying in November earns the 4 percent discount.
• April 1: unpaid taxes become delinquent.

Put the property tax line next to the others in your plan: estimating net proceeds covers the sale, and the step-by-step downsizing guide puts the dates in order. Questions about value go to the Property Appraiser and questions about payment go to the Tax Collector. A CPA or Florida attorney can review anything unusual.

When you are ready to compare homes with their tax bills in mind, you can request an introduction. Introductions go to agents on the operating team at eXp Realty, so this is not a search of the whole market, and the agent, not this site, handles the sale.
