What Is Just Value in Florida Property Tax Assessment?

Just value in Florida property tax is the county property appraiser’s estimate of what your property would sell for in a cash sale between a willing buyer and a willing seller on January 1 of the tax year. It is the starting number on your assessment, not the number you pay taxes on. Florida law stacks several caps and exemptions on top of just value to produce the assessed value and then the taxable value, and the gap between just value and taxable value is where most homeowners find real savings. Article VII, Section 4 of the Florida Constitution requires that all property be assessed at just value, and the mechanics are set out in state statute.1FindLaw.

What Just Value Actually Means

Florida Statute 193.011 defines just value as the amount a willing buyer would pay a willing seller in a cash, arm’s-length transaction, with reasonable purchase fees and costs excluded.2Justia Law. Florida Code Title XIV Chapter 193 Part I Section 193-011 Neither side is desperate. Nobody is being forced to close. Both parties have reasonable knowledge of the relevant facts, and the price reflects what the property would bring in an open, competitive market.

The date matters as much as the definition. Every county property appraiser in Florida sets just value as of January 1, and that single date controls the valuation for the entire tax year that follows.3Florida Department of Revenue. Florida Property Tax Calendar A property that doubles in value by June still carries the January 1 figure. A market drop in the fall won’t lower your bill until next year’s assessment.

The Eight Factors Appraisers Must Weigh

Appraisers do not pick a number that feels right. Statute 193.011 lists eight factors they must consider when arriving at just value:2Justia Law. Florida Code Title XIV Chapter 193 Part I Section 193-011

  • Present cash value, meaning what a willing buyer would pay a willing seller in an arm’s-length cash transaction.
  • Highest and best use, the most profitable legal use of the property given current zoning, land use regulations, historic preservation rules, and any government-imposed development moratoriums.
  • Location, including proximity to schools, employment centers, transportation, and neighborhood characteristics.
  • Size of the land and improvements.
  • Cost and replacement value, both the original purchase cost and what it would take today to rebuild existing structures.
  • Condition of the land and any buildings.
  • Income the property generates, such as rent.
  • Net sale proceeds, meaning what the seller would pocket after commissions, closing costs, and financing expenses.

Highest and best use is the factor that catches owners off guard. The appraiser does not value your home based on how you actually use it. A single-family lot zoned for multifamily could carry a higher just value than the modest house on it would suggest, because a developer could legally tear down the house and build apartments. Zoning restrictions, deed covenants, environmental rules, and temporary moratoriums all shape what counts as legally permissible, and the appraiser must account for them.

How Appraisers Translate the Factors Into a Number

Three standard approaches do most of the work. The sales comparison approach looks at recent sales of similar properties nearby and adjusts for differences; this is the workhorse for residential property. The cost approach estimates what it would cost to rebuild each structure at today’s prices, minus depreciation, and adds the land value; it fits newer buildings and specialty properties like churches that rarely trade on the open market. The income approach projects the property’s net income and converts it to a present value; it dominates valuations for apartments, offices, and shopping centers. Most parcels get looked at through more than one lens, with the appraiser weighting the results based on what fits the property.

How Just Value Becomes the Number on Your Bill

Just value is the starting point. Three more steps follow before you owe anything:

  • Assessed value is just value reduced by any applicable assessment cap. It can never exceed just value, but it can run substantially lower for long-time owners.
  • Taxable value is assessed value minus any exemptions you qualify for, such as the homestead exemption.
  • The tax bill is taxable value multiplied by the combined millage rate of every taxing authority covering your property, including the county, city, school district, and water management district. One mill equals one dollar per thousand dollars of taxable value.

For a long-time homeowner in a rising market, the assessed value can lag hundreds of thousands of dollars behind just value. That spread shows up as real money off the tax bill every year.

Why Assessed Value Usually Trails Just Value

The Save Our Homes Cap

The Save Our Homes amendment, codified in Florida Statute 193.155, limits how fast the assessed value of a homesteaded property can grow. Each year’s increase cannot exceed the lower of 3 percent or the annual change in the Consumer Price Index. In a year the CPI rises 1.8 percent, your assessed value can rise no more than 1.8 percent no matter what the market did. If just value ever drops below assessed value, the assessed value falls to meet it.4Online Sunshine. Florida Statutes Section 193.155 – Homestead Assessments

Non-homestead residential and certain commercial properties get a weaker version of this protection. Their assessed value cannot increase by more than 10 percent per year under Florida Statute 193.1554.5Online Sunshine. Florida Statutes Section 193.1554 The same floor applies: a drop in just value pulls assessed value down with it.

What Happens When You Sell or Buy

A change of ownership resets the clock. When a property sells, the new owner’s assessed value starts at the just value as of January 1 of the year following the sale, and the cap begins fresh from that point.6Florida Senate. Florida Statutes Section 193.1555 This is why buyers sometimes see sticker shock on their first tax bill: the prior owner may have had years of capped assessments, and the new bill reflects full market value. Transfers that merely correct title or shift between legal and equitable ownership do not trigger a reset.

Portability

The accumulated difference between your just value and your capped assessed value is often called your Save Our Homes benefit. Florida lets you transfer up to $500,000 of that benefit to a new homestead anywhere in the state.7Florida Department of Revenue. Save Our Homes Assessment Limitation and Portability Transfer You have three tax years from the date you give up your old homestead to establish the new one and claim the transfer, filing form DR-501T with the new county’s property appraiser by March 1 of the year you want the benefit to begin. Moving to a less expensive home transfers only a proportional share of the benefit, not the full dollar amount, so run the numbers before assuming the full savings follow you.

Exemptions That Cut Taxable Value Further

The homestead exemption is the most common way Floridians reduce taxable value, and its structure is more layered than most owners realize. Florida Statute 196.031 provides an exemption of up to $25,000 on the assessed value of your primary residence, and that first slice applies to all property taxes including school district levies.8Online Sunshine. Florida Statutes Section 196.031 – Exemption of Homesteads

Then there is a gap. Assessed value between $25,001 and $50,000 is fully taxable with no exemption. Above $50,000, a second exemption of up to an additional $25,000 kicks in, adjusted annually for inflation. For 2026, that additional exemption is worth up to $26,411.9Florida Department of Revenue. Additional Homestead Exemption Adjustment The catch: the second exemption does not apply to school district taxes. So for county and city taxes, you could see roughly $51,411 in total exemptions in 2026, while for school taxes you get only the first $25,000.

To qualify, you must hold legal or equitable title to the property, make it your permanent residence as of January 1, and file with the county property appraiser. Missing the filing forfeits the exemption for that year.

When Improvements Push Just Value Up

Adding a pool, expanding a room, or putting up an accessory structure raises your just value. New construction and additions are assessed at full market value as of the first January 1 after the work is substantially completed, and that newly assessed value sits outside the Save Our Homes cap for the first year. Your assessed value can jump by more than 3 percent in the year the improvement hits the roll. After that first assessment, the improvement becomes part of the capped base going forward.

Routine maintenance does not trigger a reassessment. Repainting, patching a roof, or swapping in a new water heater of the same model preserves what was already there. A kitchen renovation with upgraded cabinets and expanded square footage adds new value. The line falls between those two.

If the Number Looks Wrong

Every August, county property appraisers mail a Notice of Proposed Property Taxes, known as the TRIM notice (Truth in Millage). It shows your just value, assessed value, exemptions, and the taxes each local authority proposes to levy. That notice is your trigger to act if something looks off.

You have 25 days from the date the TRIM notice is mailed to file a petition with the Value Adjustment Board challenging your assessment.10FindLaw. Florida Statutes Title XIV Section 194.011 The filing fee cannot exceed $50 per parcel.11Florida Department of Revenue. PTO Bulletin 25-01 – Increased Filing Fee for Petitions Filed with the Value Adjustment Board A special magistrate appointed by the VAB hears the case, and both sides exchange evidence at least 15 days before the hearing.

The strongest evidence in most residential cases is recent sales of comparable properties. If three similar homes within a mile sold for $350,000 to $370,000 and your just value sits at $420,000, those sales speak loudly. A private appraisal from a licensed appraiser carries weight. Photographs documenting deferred maintenance, structural problems, or adverse location factors that a drive-by assessment missed all help. If the magistrate rules against you, you can appeal to circuit court within 60 days.
