How Florida Property Tax Works
Florida property tax is calculated by multiplying the assessed property value by the county millage rate. Understanding this system is critical for financial planning, particularly when purchasing high-value properties.
Assessed Value: Florida assesses property at 100% of market value determined by county property appraiser offices. Assessment is not the same as appraisal; assessors use statistical models, comparable sales data, and systematic valuation methodology rather than individual property inspection.
Millage Rate: The millage rate is expressed as dollars per thousand dollars of assessed value. A property with $3M assessed value in a county with 8.45 millage rate would owe: ($3,000,000 ÷ 1,000) × 8.45 = $25,350 annual tax before exemptions.
Key Concept: Property taxes in Florida are determined first, then exemptions are applied to reduce taxable value. This is opposite to some states where exemptions are factored into rate-setting. Florida's approach means exemption value is consistent year-to-year, but exemption benefit as percentage of tax decreases as property value increases.
Assessment Timeline: Properties are assessed annually as of January 1. New acquisitions are first assessed in the year following purchase. Assessors send notices in May; appeal deadline is typically 25 days (varies by county). Assessment appeals often result in reductions if property sold significantly below appraised value in prior year.
Homestead Exemption: Application & Benefits
The homestead exemption is Florida's primary property tax benefit, available to property owners who occupy the property as their primary residence. The exemption provides substantial tax savings but requires proper filing and verification.
Homestead Exemption Amount: The first $50,000 of assessed value is exempt from taxation. For property owners age 65+, an additional $25,000 exemption is available on assessed value between $50,000 and $75,000. Disabled or blind homeowners qualify for exemptions up to $75,000.
Example: A $3M property with $3M assessed value would normally owe taxes on full $3M. With homestead exemption, $50,000 is exempt, so taxes apply to $2,950,000. At 8.45 millage rate: tax savings = ($50,000 ÷ 1,000) × 8.45 = $422.50 annually. This modest benefit applies regardless of property value, and a $5M property receives the same $422.50 benefit.
How to Apply for Homestead Exemption
Important Distinction: Homestead exemption requires that the property be your primary residence where you actually live. Ownership is not sufficient; you must occupy the property. Vacation homes, investment properties, and rental properties do not qualify, even if owned by Florida residents. Out-of-state owners cannot claim homestead exemption.
Save Our Homes Cap: Limiting Assessment Increases
The Save Our Homes (SOH) amendment, enacted in 1992, provides essential protection against property tax runaway by capping annual assessment increases on homestead properties.
The 3% Cap: Once homestead exemption is granted, assessed value cannot increase more than 3% annually, regardless of actual market appreciation. This cap remains in effect as long as ownership is unchanged and property maintains homestead status.
Cap Resets on Transfer: When property is sold and new owner takes homestead exemption, assessed value is reassessed at current market value, and the cap resets. The new owner then receives 3% cap protection going forward. This creates significant tax advantage for long-term homeowners and disadvantage for new purchasers.
Example of Cap Benefit: Purchased $3M property in 2005 with homestead exemption. Initial assessed value (after $50K exemption): $2,950,000. Over 20 years with 3% annual cap, assessed value would grow to approximately $5,170,000 (accounting for 3% annual increases). Actual market value in 2025: $5,800,000. Homeowner pays tax on $5,170,000 instead of $5,800,000, saving approximately $5,300 annually.
Widow's Exemption (Transfer on Spouse's Death): If homestead owner dies, surviving spouse can retain property with the same assessed value without reset. The 3% cap continues under surviving spouse's ownership, providing significant estate planning advantage. This exemption does not apply if property is transferred to adult children or non-spouse heirs.
Tax Planning Implication: The 3% cap creates long-term cost advantage for primary residence ownership but disadvantage for new purchasers entering the market. When evaluating luxury property purchases, calculate expected property tax burden assuming full market reassessment; do not assume prior owner's capped assessment will transfer to you.
Portability: Moving Your Tax Cap
Florida's portability rule allows homestead property owners to transfer accumulated Save Our Homes benefits to a new primary residence, provided the new property value doesn't exceed a threshold amount.
Portability Mechanism: When you sell your old homestead property and purchase a new one, you can transfer the 3% cap accumulated benefit to the new property. If the new property is worth significantly more, portability applies only partially.
Portability Limits: The amount of accumulated benefit that can be transferred is limited to the lesser of: (1) the difference between the new property's market value and your old property's most recent assessment, or (2) the difference between the new property's market value and 125% of your old property's assessed value.
Example: Old property purchased 2000 for $1.2M; current assessed value $1.5M with 3% annual cap; market value $2.8M. New property purchase price $5M. Accumulated benefit from old property (difference between market value $2.8M and assessed value $1.5M = $1.3M benefit) can transfer, but capped at 125% difference. Benefit transfers but new property begins assessment at closer to market value with cap going forward.
Portability Filing: You must file for portability when you apply for homestead exemption on the new property. Deadline is same as homestead application (March 1 for current tax year benefit). Provide documentation of previous homestead property's assessed value and transfer request.
Property Tax Rates by South Florida County
Millage rates vary significantly by county and special districts. South Florida's primary counties show distinct tax profiles affecting long-term ownership costs.
| County | County Millage | Total Millage* | Annual Tax ($3M Property) | Annual Tax ($5M Property) |
|---|---|---|---|---|
| Palm Beach | 4.89 | 8.45 | $25,350 | $42,250 |
| Broward | 5.12 | 8.62 | $25,860 | $43,100 |
| Miami-Dade | 5.68 | 8.95 | $26,850 | $44,750 |
| Martin County | 5.42 | 8.78 | $26,340 | $43,900 |
| St. Lucie | 5.85 | 9.12 | $27,360 | $45,600 |
*Total millage includes county, municipal, school, and special district assessments; varies by specific address within county.
County Analysis: Palm Beach County maintains lowest overall millage rate at 8.45, translating to approximately $400/year lower tax bill than Miami-Dade County for equivalent $3M property. Over 30-year ownership, Palm Beach location saves $12,000+ in property taxes on single property. This advantage compounds significantly for owners holding multiple properties.
Non-Homestead Properties & Investment Tax Treatment
Investment properties, vacation homes, and rental properties do not qualify for homestead exemption or 3% cap protection. These properties are assessed at full market value with unlimited annual increases.
Non-Homestead Tax Burden: An investment property purchased for $3M will be assessed at $3M and subject to full millage rate without exemptions. No 3% cap limits increases. As property appreciates or market-based assessments rise, tax burden increases proportionally.
Tax Implications for Investors: Investment property owners should factor full property tax burden into cap rate calculations. A property generating $120,000 annually in net rental income with $27,000 property tax liability yields 3.45% cap rate. Identical property owned as primary residence (homestead) would have capped assessment growth, significantly improving long-term return profile.
Depreciation Benefit: While investment properties don't receive property tax exemptions, they do qualify for depreciation deductions on federal income taxes. Rental properties can depreciate structure value over 27.5 years, creating substantial tax deductions that offset rental income. Consult tax professional regarding depreciation recapture on eventual sale.
Additional Florida
Tax Exemptions
The homestead exemption is the most widely known, but Florida offers several additional property tax exemptions that stack on top of it. Depending on your situation, these can meaningfully reduce your annual tax bill. Each exemption is applied for separately through your county property appraiser's office.
These exemptions do not apply automatically. You must file a separate application for each one you qualify for, typically by the same March 1 deadline as homestead. Supporting documentation is required in each case, such as VA disability rating letters, death certificates, or physician certifications. If you believe you may qualify for any of these, contact your county property appraiser's office directly; they can tell you exactly what applies to your situation and walk you through the process.
Filing Process & Deadlines
Proper homestead exemption filing is essential to ensure tax benefits apply and to avoid late-filing penalties. The process is straightforward but deadline-sensitive.
Assessment Appeal Process: If you believe assessed value exceeds market value, file an appeal (called "Value Adjustment Board" appeal in most counties) by deadline. Appeals often succeed if property sold below assessment in prior year or comparable properties sold at lower prices. Many counties offer informal settlement conferences before formal hearing.
