Commercial property tax in Florida is calculated by the county property appraiser, who sets a just value for your building as of January 1 each year, applies a constitutional 10% annual cap on assessment increases and any exemptions you qualify for, and hands that taxable value to local taxing authorities who multiply it by their millage rates. Because Florida has no state income tax, these bills fund most of local government, and they can be substantial on office buildings, shopping centers, warehouses, and apartment complexes. The rules below determine what you owe and how to push back if the number looks wrong.
How Your Property Gets Valued
Every county has a property appraiser who establishes just value, which is essentially fair market value, as of January 1.1Florida Department of Revenue. Florida Property Tax Calendar State law requires the appraiser to weigh eight factors, including present cash value, highest and best use, location, size, replacement cost, condition, income produced, and net proceeds from a hypothetical sale.2Florida Legislature. Florida Code 193.011 – Factors to Consider in Deriving Just Valuation
In practice, appraisers rely on three methods. The income capitalization approach converts expected rental income into a present value and is the usual tool for income-producing commercial buildings. The sales comparison approach uses recent sales of similar properties. The cost approach estimates what it would take to rebuild the improvements, less depreciation. The appraiser isn’t locked into one method and generally blends whichever best fit the property and the available data.
The 10% Assessment Cap
Article VII, Section 4 of the Florida Constitution caps the annual increase in assessed value on non-homestead property at 10%.3Florida Senate. The Florida Constitution That covers both non-homestead residential property with nine units or fewer and commercial and industrial real estate, under slightly different subsections. Once the cap applies, your assessed value can only grow 10% per year even if market value jumps much more.
The cap resets on a change of ownership or control. For non-homestead residential property, the reset is automatic at the next January 1.4Florida Senate. Florida Code 193.1554 – Assessment of Nonhomestead Residential Property For other commercial and industrial property, state law also requires a reset. After the reset, the property is reassessed at full just value and the 10% cap starts over from that new baseline.
What Triggers a Reset
A change of ownership or control isn’t just a deed sale. It includes any sale, foreclosure, or transfer of legal or beneficial title. It also includes a cumulative transfer of more than 50% of the ownership of the entity holding the property since it was last assessed at just value. Sell controlling interest in the LLC that owns a retail center and the cap resets, even though the deed never moved.5Florida Department of Revenue. Change of Ownership or Control Non-Homestead Property
Owners are supposed to report these changes to the property appraiser on Form DR-430 unless a recorded instrument already documents the transfer. Failing to do so and continuing to enjoy a capped assessment carries back taxes, 15% annual interest, and an additional penalty of 50% of the taxes avoided. The appraiser is also required to record a tax lien against the property.5Florida Department of Revenue. Change of Ownership or Control Non-Homestead Property
Millage Rates and the TRIM Notice
Your assessed value, less exemptions, is only half the bill. The other half is the millage rate set by each local taxing authority. One mill equals one dollar per $1,000 of taxable value, and county commissions, school boards, cities, and special districts each set their own rate. They all stack on your bill.6Florida Department of Revenue. A Florida Homeowner’s Guide – Millage A commercial building with $2 million in taxable value in a jurisdiction totaling 18 mills owes $36,000 for the year.
Florida law doesn’t impose a flat millage ceiling, but it does restrict year-over-year increases. Rates above a rolled-back threshold require a supermajority vote, and larger increases can require a referendum.7Florida Legislature. Florida Code 200.065 – Method of Fixing Millage
In mid-August, the property appraiser mails a Truth in Millage (TRIM) notice showing your proposed assessed value, exemptions, and the tentative taxes each authority plans to levy.8Florida Legislature. Florida Code 200.069 – Notice of Proposed Property Taxes Read it carefully. You have 25 days from the mailing date to file an appeal, and that deadline is printed on the notice.9Florida Senate. Florida Code 194.011 – Assessment Notice; Objections to Assessments In most counties, the window closes in early to mid-September.
Exemptions Commercial Owners Can Use
Homestead doesn’t apply to commercial property, but several other reductions do.
Tangible Personal Property
Business equipment, furniture, and computers at your property are taxed separately as tangible personal property. State law provides a $25,000 exemption on each return, which can shelter smaller inventories entirely.10Florida Legislature. Florida Code 196.183 – Exemption for Tangible Personal Property You claim it by filing a tangible personal property return with the county property appraiser by April 1.11Florida Department of Revenue. Tangible Personal Property New filers who miss April 1 lose the $25,000 exemption for the year entirely.
Charitable, Religious, and Educational Use
Property owned and used predominantly for charitable, religious, scientific, literary, or educational purposes can qualify for a full or partial ad valorem exemption. “Predominantly” is the operative word: if part of the building is used for a non-exempt purpose, only the qualifying portion gets the exemption, though incidental non-exempt use won’t disqualify the property.12Florida Legislature. Florida Code 196.196 – Determining Whether Property Is Entitled to Charitable, Religious, Scientific, or Literary Exemption Application deadline is March 1.
Agricultural Classification
Land used primarily for bona fide commercial agriculture can be assessed on its agricultural use rather than full market value, often called the greenbelt classification. The return is due to the property appraiser by March 1; missing that date waives the classification for the year unless the appraiser finds extenuating circumstances.13Florida Senate. Florida Code 193.461 – Agricultural Lands; Classification and Assessment The appraiser weighs how long the land has been farmed, continuity of use, purchase price, and whether the owner follows accepted agricultural practices. No minimum acreage applies, but the use must be genuine commercial agriculture.
Renewable Energy Devices
On non-residential property, 80% of the assessed value attributable to a qualifying renewable energy source device is excluded from taxation.14Florida Senate. Florida Code 193.624 – Assessment of Renewable Energy Source Devices Qualifying equipment includes solar panels, photovoltaic modules, wind turbines, geothermal heat pumps, and related storage and power-conditioning systems. Backup equipment you’d need regardless of the renewable install doesn’t count. The exemption is set to expire at the end of 2037.
Economic Development
Counties and municipalities that have passed a voter referendum can offer ad valorem exemptions up to 100% on improvements and tangible personal property for new or expanding businesses, lasting up to 10 years for most businesses and up to 20 years for data centers.15Florida Senate. Florida Code 196.1995 – Economic Development Ad Valorem Tax Exemption Not every jurisdiction offers it, and local governments set their own eligibility rules. Where available, the application is generally due March 1.
Pay Early, Pay Less
Tax bills go out in November. Paying that month earns a 4% discount, dropping to 3% in December, 2% in January, and 1% in February. In March, you owe the full amount.16Florida Senate. Florida Code 197.162 – Tax Discount Payment Periods On a $50,000 bill, paying in November instead of March saves $2,000. Across a large portfolio, the savings scale fast.
Appealing Your Assessment
If the appraiser’s number is too high, you can petition the Value Adjustment Board (VAB). The process is accessible, but strict deadlines and evidentiary standards sink many commercial petitions on procedure alone.
Filing the Petition
The appeal starts with Form DR-486, available from the county property appraiser or the Department of Revenue.17Florida Department of Revenue. Petition to the Value Adjustment Board – Request for Hearing File within 25 days of the TRIM mailing, typically by early to mid-September.9Florida Senate. Florida Code 194.011 – Assessment Notice; Objections to Assessments The petition needs your parcel number and a clear statement of why the assessment is wrong, whether inflated market value, a classification error, or both. Filing fees are non-refundable and generally run $15 to $50 depending on the county.
Burden of Proof
The appraiser’s assessment carries a legal presumption of correctness. You must show by a preponderance of the evidence that the assessed value doesn’t represent just value, doesn’t reflect the correct use classification, or was reached through appraisal practices that departed from how the appraiser treated comparable properties in the same county.18Florida Senate. Florida Code 194.301 – Burden of Proof Clear that bar and the presumption drops; the VAB then sets value based on the competent evidence in the record.
Useful evidence includes a recent independent appraisal from a certified appraiser, detailed income and expense statements, comparable sales that contradict the appraiser’s numbers, and documentation of deferred maintenance or environmental problems. Photos, repair estimates, and lease agreements all help. A special magistrate hears the case and issues a recommendation to the board.
You Still Have to Pay
Filing a petition does not pause your tax bill. If you’re challenging value, you must pay at least 75% of the ad valorem taxes, less any applicable early-payment discount, before taxes become delinquent on April 1. If you’re challenging a denied exemption or classification, you must pay the amount you admit in good faith that you owe. Miss the required payment and your petition is automatically denied.19Florida Legislature. Florida Code 194.014 – Partial Payment of Ad Valorem Taxes Win and you receive a refund of the overpayment. Lose and you owe the balance plus accrued interest.
What Happens if the Bill Goes Unpaid
Taxes are due November 1 and delinquent on April 1 of the following year.20Florida Legislature. Florida Code 197.333 – When Taxes Due; Delinquent Once delinquent, a 3% penalty is added and the tax collector must sell a tax certificate against the property, usually at a June auction.21Florida Legislature. Florida Code 197.432 – Sale of Tax Certificates for Unpaid Taxes The certificate is a lien, not a deed, so the holder gains no ownership and no right to enter the property. To clear the lien, the owner redeems it by paying the delinquent taxes, interest, and costs.
Two years after April 1 of the year the certificate was issued, the certificate holder can apply for a tax deed, which forces the property to public auction. For any commercial owner, letting unpaid taxes advance to a tax deed application is an outcome to avoid at nearly any cost. Redeem the certificate, work out a payment arrangement, or sell before it gets that far.
