JournalHomestead Exemption and Property Tax: Questions to Verify Before You Close
Florida's homestead exemption and Save Our Homes assessment cap can significantly affect carrying costs, but only if you understand how they work, who qualifies, and what happens when a property changes hands.
Miami New Realty
Property taxes are a significant and recurring cost of homeownership in Florida, and Miami-Dade County's assessment and collection system has specific features that affect what you pay and how dramatically that can change when a property is sold. The homestead exemption is not automatic, it is not always available to everyone, and its interaction with the Save Our Homes assessment cap creates a phenomenon known as 'portability' that has real value for certain buyers, and that disappears for others. Understanding this landscape before you close helps you build accurate long-term cost projections and ask the right questions of the right professionals.
What Is the Florida Homestead Exemption?
Florida's homestead exemption reduces the assessed value of a primary residence for property tax purposes. The most common exemption applies to properties with an assessed value above certain thresholds, and there are additional exemptions for qualifying senior homeowners, veterans with disabilities, and other categories. The exemption applies only to a property that the owner declares as their permanent primary residence. Eligibility requirements, application deadlines, and exemption amounts are set by state law and administered by the county property appraiser. In Miami-Dade County, the Property Appraiser's office is the authoritative source for current exemption criteria and procedures. Do not rely on what a seller or their agent says the taxes will be; verify directly with the appraiser's office.
Save Our Homes and the Assessment Cap
Florida's Save Our Homes (SOH) amendment limits the annual increase in the assessed value of a homestead property to three percent or the change in the Consumer Price Index, whichever is lower. This cap is a significant protection for long-tenured homeowners, but it also means that a property's assessed value can drift far below its market value over time. When that property sells, the cap resets. The new owner's assessed value is typically reset to market value in the year of sale, and any existing SOH cap benefit the prior owner enjoyed does not transfer to the buyer. This means the tax bill the seller was paying may be substantially lower than what the new owner will pay, even on the identical property.
Understanding Portability
Florida allows homeowners who have accumulated a Save Our Homes benefit (the difference between assessed value and market value, called 'SOH differential' or 'portability benefit') to transfer up to $500,000 of that benefit to a new homestead property. Portability is available to buyers who previously owned a homestead property in Florida; it does not apply to first-time Florida homeowners or buyers without a prior Florida homestead. If you currently own a homestead in Florida and are buying a new one, consult a tax professional about whether and how much portability you can apply. There are deadlines and procedures involved.
How to Estimate Your Post-Purchase Tax Bill
The seller's tax bill is almost never a reliable indicator of what you will pay as the new owner. To estimate your actual tax obligation, visit the Miami-Dade Property Appraiser's website, which has a tax estimator tool that approximates taxes based on purchase price and available exemptions. Use it before you finalize your offer and your financial projections. Your mortgage lender will also estimate taxes for escrow purposes, but verify their estimate against the county's tool. If you have questions about specific exemptions or your eligibility, contact the Property Appraiser's office directly or consult a licensed CPA with Florida property tax experience.
Non-Homestead Properties and Investment Properties
Properties that are not a primary residence, rentals, second homes, and investment properties, do not qualify for the homestead exemption or the Save Our Homes cap. Non-homestead properties are assessed annually at market value and subject to the full millage rate without the exemption reductions. If you are buying an investment property or a part-time residence in Miami, model your tax costs accordingly. Additionally, short-term rental operations may be subject to county and city occupancy taxes and registration requirements that are separate from property taxes; verify current requirements with Miami-Dade County and, if applicable, the municipality in which the property is located.
Property taxes in Miami-Dade County are not a fixed expense; they are shaped by your eligibility for exemptions, the seller's prior tax treatment of the property, and the county's annual assessment process. Building accurate tax projections into your buying decision requires more than reading the prior year's tax bill. The resources exist to get an accurate estimate; use them, and consult qualified professionals when the specifics of your situation require interpretation.
