Every year, I watch buyers close on homes in Miami — sometimes beautiful, expensive homes in neighborhoods like Coral Gables or Coconut Grove — and then miss the homestead exemption deadline because nobody told them it existed or how critical it was to file. That's money left on the table. Real money. And depending on how long they plan to stay in the home, it can compound into tens of thousands of dollars over time.
I'm Agu Ukaogo, a South Florida luxury real estate advisor and licensed insurance professional brokered through Premier Partners | Real Brokerage. My north star is simple: Buy the home. Protect the family. Build the legacy. That third part — building the legacy — is impossible if you're overpaying on property taxes because you didn't file on time or didn't understand what you were entitled to. This guide covers everything: what the homestead exemption is, how much you can save, how to apply, the Save Our Homes cap, portability, common mistakes, and what happens when you sell. Read it. Share it with anyone who just bought a home in Florida.
What Is the Florida Homestead Exemption?
The Florida homestead exemption is a constitutional benefit that reduces the assessed value of your primary residence for property tax purposes. It was established in the Florida Constitution — Article VII, Section 6 — and applies to any Florida homeowner who uses the property as their permanent, primary residence.
In practical terms, the homestead exemption does two things for you:
- It reduces your assessed value by up to $50,000. The first $25,000 of exemption applies to all taxing authorities — county, city, and school district. The second $25,000 applies to all authorities except the school district tax, and it only applies to assessed values between $50,000 and $75,000. For most Miami-Dade homeowners whose properties are assessed well above $75,000, the net exemption is typically worth approximately $750 to $1,000 per year in direct tax reduction, depending on your combined millage rate.
- It activates the Save Our Homes cap. This is the bigger benefit by far. Once you have homestead, your property's assessed value cannot increase by more than 3% per year, or the Consumer Price Index (CPI) — whichever is lower — regardless of how much the market value of your home has increased. In a market like Miami, where property values have appreciated dramatically over the past decade, this cap can mean your assessed value is significantly below your home's actual market value.
The combination of these two benefits makes the homestead exemption one of the most powerful wealth preservation tools available to Florida homeowners — and one that requires a timely application to activate. It is not automatic. You have to file.
How Much Can You Save?
The savings from Florida's homestead exemption depend on your property's assessed value and your local millage rate — the tax rate expressed in mills (dollars per $1,000 of taxable value). Miami-Dade County's combined millage rate, including county, city (varies by municipality), and school district, typically runs between 18 and 22 mills depending on where in the county you're located, which translates to a total effective rate of roughly 1.8% to 2.2% of assessed value.
Here's a real-world savings example for a Miami-Dade homeowner:
Sample Calculation — $2.5M Home in Coral Gables
That last number is the one that changes everything. The direct exemption reduction of $50,000 saves you approximately $1,000 per year. That's real money. But the Save Our Homes cap — which limits your assessed value increase to 3% per year while the market may be appreciating at 5%, 7%, or more — is the benefit that compounds dramatically over time. A homeowner who bought in Coral Gables in 2015 and maintained their homestead may have a taxable assessed value today that is $500,000 to $700,000 below their actual market value. That represents $10,000 to $14,000 per year in property tax savings at current rates. That's the real story of the homestead exemption, and it's why buying here and staying here is such a powerful wealth-building strategy.
Florida's legislature passed a constitutional amendment that voters approved, set to expand the homestead exemption from $50,000 to $250,000 by 2028. If it takes full effect as structured, the direct annual tax savings on a Miami-Dade home could increase from roughly $1,000 to $5,000 or more per year — a massive benefit for existing homeowners and a compelling argument to establish homestead status before that expansion takes effect.
Who Qualifies?
The eligibility requirements for the Florida homestead exemption are straightforward, but they need to be met precisely. All of the following must be true as of January 1st of the tax year in which you're applying:
- You must own the property. Title must be in your name, your trust, or your co-ownership arrangement. Properties owned by LLCs or corporations generally do not qualify, though there are trust structures that do.
- You must use the property as your permanent, primary residence. This is not a vacation home. It is not a rental. It is the home where you live, sleep, and receive your mail as of January 1st.
- You must be a Florida resident as of January 1st. Evidence of Florida residency includes a Florida driver's license, Florida vehicle registration, Florida voter registration, and federal income tax returns listing the Florida address.
- You cannot claim a primary residence exemption in another state. You cannot have homestead in Florida and simultaneously claim a primary residence or equivalent exemption in New York, California, or any other state. Florida will catch this — the state cross-references applications with other states' exemption databases.
If you're a snowbird — someone who spends part of the year in Florida and part in another state — you need to make a genuine commitment to Florida as your permanent residence to claim homestead. That means surrendering your other-state driver's license, updating your voter registration, and filing your federal returns from your Florida address. Many buyers who relocate from high-tax states like New York or California go through this process as part of their move to Miami, and I work with their advisors to ensure the documentation is in order.
How to Apply — Step by Step
The application process is managed by your county property appraiser's office. In Miami-Dade, that's the Miami-Dade County Property Appraiser. Here's the exact process:
- Close on your home before January 1st. To claim homestead for a given tax year, you must own and occupy the property as your primary residence as of January 1st of that year. If you close on December 15th, you can potentially claim homestead for the following year (with an application due March 1st). If you close on January 15th, you cannot claim homestead until the year after.
- Gather your documentation. You'll need: your Florida driver's license or ID showing the property address, your Florida vehicle registration, your Social Security number, and proof of ownership (your deed or tax bill). If you're establishing Florida residency, also have your voter registration confirmation available.
- File your application by March 1st. The filing deadline is March 1st of the tax year. File online through the Miami-Dade County Property Appraiser's website, in person at a property appraiser office, or by mail. Applications received after March 1st are not accepted for that year — you would need to wait and apply for the following tax year. There is no grace period.
- Verify your exemption was approved. After the property appraiser processes your application, you'll receive a Notice of Proposed Property Taxes (TRIM Notice) in August. Verify that the homestead exemption appears on the notice. If it doesn't, contact the property appraiser's office immediately — you have a limited window to dispute and correct the exemption before the tax roll is certified.
- Renew automatically — but confirm annually. Once approved, the homestead exemption renews automatically each year as long as your eligibility status doesn't change. However, I always tell my clients to verify their TRIM notice each August to confirm the exemption is still applied correctly.
The Save Our Homes Cap Explained
The Save Our Homes (SOH) cap, enacted through a 1992 constitutional amendment, is the provision that limits how much your assessed value can increase each year once you have homestead status. Specifically, it limits the increase in assessed value to the lesser of: 3% per year, or the percentage change in the Consumer Price Index (CPI).
In years when CPI is below 3% — which has been more common historically — your assessed value increases by only the CPI percentage. In years of higher inflation where CPI exceeds 3%, the cap holds your assessed value increase to exactly 3%.
What this means in practice: in a city like Miami where market values have risen dramatically — in some neighborhoods doubling or tripling over the past decade — long-term homestead holders are paying taxes on assessed values that may be 30%, 40%, or even 50% below the current market value of their home. This is not a loophole or an error. It is exactly the intended effect of the Save Our Homes cap — to protect Floridians from being taxed out of their homes due to rising market values.
The flip side: when you buy a home that has been homesteaded by its previous owner for many years, you are buying at market value but the existing SOH cap does not carry over to you. You start fresh — your property will be assessed at market value in the year of purchase, and you begin accumulating your own SOH cap benefit from scratch when you establish your homestead.
A homeowner who bought a Coconut Grove home for $1.8 million in 2014 and maintained homestead through 2026 might have an assessed value today of $2.2 to $2.4 million, even if the market value has reached $3.5 million. That SOH benefit — roughly $1.1 to $1.3 million below market value — is saving them $20,000 to $26,000 per year in property taxes. That is not a rounding error. That is a significant, compounding financial advantage that accrues to long-term Florida homeowners.
Portability — Taking Your Cap With You
One of the most misunderstood benefits of Florida's homestead system is portability — the ability to transfer your accumulated Save Our Homes benefit when you move from one Florida homestead to another. If you've been in your current Florida home for several years and have built up a large SOH benefit (the gap between your market value and assessed value), you can take up to $500,000 of that benefit with you when you buy your next primary residence in Florida.
Here's how portability works:
- Calculate your portability benefit. Your portability benefit is the difference between the market value and the assessed value of your previous homestead at the time you sell or move. If your home's market value was $3 million and your SOH-capped assessed value was $2.1 million, your portability benefit is $900,000 — but the transfer is capped at $500,000.
- Transfer within two years. You must establish a new Florida homestead within two years of abandoning the previous one to qualify for portability. If you sell in January 2026, you must have a new homestead in place by January 2028.
- File the DR-501T form. The portability transfer is not automatic. You must file form DR-501T with the county property appraiser of your new home's county at the same time you file your new homestead exemption application. Both forms are due by March 1st.
- The benefit reduces your new assessed value. If you transfer a $500,000 portability benefit to a new home with a market value of $2.5 million, the property appraiser will reduce the assessed value of your new home by up to $500,000, immediately reducing your tax bill. You then continue accumulating a new SOH cap from that reduced assessment base.
Portability is a game-changer for buyers who are upsizing within Florida. Many of my clients who are moving from a smaller Miami home to a luxury property in Coral Gables or Coconut Grove are carrying significant portability benefits — and I make sure their advisors incorporate those numbers into the buying strategy before we go under contract.
Common Mistakes to Avoid
These are the homestead mistakes I see buyers make most frequently — and the ones that cost real money when they happen:
- Missing the March 1st deadline. There is no extension, no grace period, and no exception for people who "just didn't know." If you close on a home in 2025 and don't file by March 1, 2026, you pay full market-value taxes for 2026 and have to wait until 2027 to get the benefit. File the day after closing if you can — or at minimum, put March 1st on your calendar with a reminder in December and January.
- Still claiming a primary residence exemption in another state. Florida cross-checks homestead applications against other states' databases. If you're claiming homestead in Florida while also claiming a primary residence exemption in New York or New Jersey, expect a notice, a back-tax bill, and potential penalties. Establish Florida residency fully before filing.
- Titling the property in an LLC or corporation without understanding the consequences. Standard LLCs and corporations cannot claim homestead on Florida property. If you're holding the property in an entity for liability or estate planning reasons, work with your attorney to structure it in a way that preserves homestead eligibility — typically through a revocable living trust where you are the beneficiary.
- Not filing portability when upsizing. I have spoken to clients who moved to a larger home and left $300,000 or $400,000 in portability benefits behind simply because no one told them to file the DR-501T. File portability. Always.
- Assuming the exemption carries over to the buyer when you sell. It does not. Your buyer must establish their own homestead. If you're selling, make sure your buyer's agent is informing them about the homestead timeline so they don't miss the filing window.
- Renting the property without understanding the effect on homestead. If you move out and rent your homestead property, you lose the homestead exemption for the rental period — and you lose the accumulated SOH cap benefit. The property is reassessed at market value when homestead is lost. This can be a very expensive mistake on a property that has appreciated significantly.
What Happens When You Sell?
When you sell your homestead property, several things happen simultaneously that affect both you and your buyer — and most sellers don't fully understand either side of the picture.
For you as the seller: your homestead exemption terminates on January 1st of the year after the year of sale (or when you abandon the property, whichever comes first). If you're buying another Florida home, you need to file portability within two years. If you're leaving Florida permanently, the portability benefit is lost — you cannot take it to a home in another state.
For your buyer: they will receive the property at market value assessment in the year of purchase, regardless of what your SOH-capped assessed value was. This is called the "reset" provision. If you've been paying taxes on a $1.5 million assessed value but the property sells for $3 million, your buyer will receive a TRIM notice in August reflecting a $3 million market value assessment, and their taxes will be calculated on something very close to that number (the exact methodology depends on the sale date and county). This is often a surprise to buyers — particularly those moving from states where the tax assessment follows the sale price automatically — and I always prepare my luxury buyers for this reality so the first property tax bill isn't a shock.
For buyers purchasing a property from a long-term homesteaded owner, I recommend proactively calculating what the post-purchase property tax bill will look like based on the new market value assessment. I provide this calculation as part of the carrying cost analysis I run for every buyer client before they make an offer.
In the luxury market, this reset can be significant. A Coral Gables estate that traded between family members or has been homesteaded since 2005 may carry a $1.2 million assessed value despite a $4 million market value. A new buyer at $4 million should budget for property taxes on approximately $3.95 million (after their own homestead exemption). The annual tax difference can be $50,000 or more. I build this into every offer analysis I provide so my clients are never surprised after closing.
Frequently Asked Questions — Florida Homestead Exemption
Who qualifies for the Florida homestead exemption?
To qualify, you must own the property, use it as your permanent primary residence, be a Florida resident — with a Florida driver's license, voter registration, or other evidence of permanent residency — and apply by March 1st of the tax year. You cannot simultaneously claim a primary residence exemption in another state. LLCs and corporations typically cannot claim homestead, though properly structured trusts can. The key date is January 1st of the tax year: you must own and occupy the property as your primary residence as of January 1st to qualify for that year's exemption.
How much does the Florida homestead exemption save on property taxes?
The direct exemption reduces your assessed value by up to $50,000, saving roughly $750 to $1,000 per year in Miami-Dade at current millage rates. But the far larger benefit is the Save Our Homes cap, which limits your annual assessed value increase to 3% or CPI — whichever is lower — regardless of actual market appreciation. On a Miami luxury home that has appreciated significantly over 10+ years, this cap can mean your taxable assessed value is $500,000 or more below your current market value, saving you $10,000 to $20,000+ annually in property taxes. That compounding benefit is the real value of establishing homestead and staying in place.
What is homestead portability in Florida and how does it work?
Portability allows you to transfer your accumulated Save Our Homes benefit — up to $500,000 — from your previous Florida homestead to a new Florida homestead when you move. The portable amount is the difference between your previous property's market value and its SOH-capped assessed value at the time you sell. To claim portability, you must establish your new homestead within two years of abandoning the previous one and file form DR-501T with the county property appraiser at the same time you apply for your new homestead exemption. Portability does not carry to homes outside Florida and is not automatic — you must actively file.
What happens to my homestead exemption when I sell my home?
When you sell your homestead property, the exemption and the Save Our Homes cap do not transfer to the buyer. The new owner's property is reassessed at market value in the year of sale, and they must establish their own homestead exemption by January 1st and apply by March 1st. As the seller, you should capture your portability benefit by filing the DR-501T within two years of selling if you're buying another Florida home. If you're leaving Florida, the portability benefit is lost. I prepare all of my buyer clients for the post-purchase tax reality by calculating the expected assessment at market value before they make an offer — no first-year surprises allowed.
