Florida voters just handed Miami homeowners the biggest property tax break in a generation, and the clock on who qualifies first is already ticking. Amendment 3 passed on November 3 with roughly 62 percent of the vote, clearing the 60 percent threshold and raising the non-school portion of the Florida homestead exemption from its current level to $150,000 in 2027 and $250,000 in 2028. For a Miami homeowner, that is real money. For anyone planning a move to Miami, the date on your Florida driver license suddenly matters more than the date on your closing docs. Here is what actually changed with Amendment 3, what the December 31, 2026 residency deadline really means for your Miami homestead exemption, and how I would play it if I were advising a client this week.
What Amendment 3 Actually Changes
Today, a Miami homestead gets a total exemption of up to $51,411 under the formula set by the Florida Department of Revenue, split between a $25,000 piece that applies to all taxing authorities (including schools) and a secondary piece that applies only to non-school millages. Amendment 3 leaves the school portion alone at $25,000, and lifts the non-school portion so the total exemption reaches $150,000 for the 2027 tax roll and $250,000 for the 2028 tax roll, with CPI adjustments kicking in January 1, 2029. The Florida Chamber of Commerce summary of Amendment 3 spells out the phase-in, and the new figures first show up on the August 2027 TRIM notices and the November 2027 tax bills.
The amendment also does two other things that are not getting enough attention. It cuts the annual assessment cap on non-homestead property from 10 percent to 5 percent for non-school levies starting in 2027, which quietly reshapes the math on second homes, condos held for seasonal rentals, and small landlord portfolios across Miami-Dade. And it earmarks the reduced county and city revenue to a defined list of priorities: public safety, education, infrastructure, natural resources, bonds, retirement benefits, and basic operations. That spending guardrail is a structural shift Miami-Dade and its municipalities will be absorbing for years.
The December 31, 2026 Residency Deadline, Decoded
This is the piece almost everyone is misreading. The larger exemption does not apply automatically to anyone who owns a Florida home. It applies in 2027 only to permanent Florida residents as of December 31, 2026 who then qualify for the homestead exemption under existing law. Anyone who establishes Florida residency on or after January 1, 2027 starts with a smaller $50,000 new-resident exemption and has to wait until the fifth year of holding a Florida homestead before the full exemption level kicks in. The Pinellas County Property Appraiser's Amendment 3 FAQ lays out the mechanics in plain language, and a detailed legal explainer from Bilzin Sumberg walks through what counts as establishing Florida residency.
Residency is a facts and circumstances test, not a single box you check. The signals that matter most are a Florida driver license, Florida vehicle registration, voter registration in Florida, a filed declaration of domicile, and the paper trail of where you actually live: utility accounts, mailing address, financial accounts, and where you physically spend your time.
Here is the detail that trips people up. Establishing Florida residency and claiming a homestead exemption on a specific property are two different events. You can be a permanent Florida resident on December 31, 2026 without yet owning the home you eventually make your homestead, and that order matters.
If You Already Own a Miami Home
You are in the strongest position, and the main job is to not blow it. If the property is already your filed homestead and you remain a Florida resident through December 31, 2026, you are on track to receive the increased exemption automatically for the 2027 tax year, subject to the implementing legislation Tallahassee will write over the winter.
Where I see owners stumble is in life changes between now and then. Selling a homestead and renting while you shop for the next one, buying a second home and shifting your domicile to it mid-year, inheriting a Florida property, or transferring title between individual ownership and a trust can all disturb the record. If any of that is on your calendar, confirm with the Miami-Dade County Property Appraiser that your 2026 homestead record is clean before year end.
If You Are Moving to Miami, Timing Just Got Expensive
The five-year wait for new residents is where the real strategy lives. For a client relocating from New York, Chicago, or the Northeast, the difference between establishing Florida residency on December 30, 2026 and establishing it on January 2, 2027 is roughly four years of a $200,000 reduction in assessed value sitting on a Miami tax bill. I ran the math with a client last week on a $1.6M Coral Gables single-family home against the 2025 Miami-Dade aggregate non-school millage, and the difference in total property tax over that five-year head start ran into the mid five figures.
If you are serious about Miami and your calendar has any flexibility, the moves that preserve your options are straightforward:
- Switch your driver license to Florida before December 31, 2026
- Register to vote in Florida
- File a declaration of domicile with the clerk of court in the county you are moving to
- Register your vehicles in Florida
- Update your mailing address, financial accounts, and employer records
- If you have not yet closed on a Miami home, close by March 1, 2027 and apply for the homestead exemption using Form DR-501 through the property appraiser
You do not have to own a Florida home on December 31, 2026 to be a Florida resident that day. If you are renting while you shop the market, the residency clock starts the moment you establish a domicile, not the moment you close.

What Did Not Change, and Why That Matters
Three features of Florida's property tax system Amendment 3 does not touch. Save Our Homes still caps the annual rise in assessed value on a homesteaded property at 3 percent or CPI, whichever is lower. Portability still lets you transfer up to $500,000 of Save Our Homes savings to a new Florida homestead within three tax years. And the $25,000 school portion of the exemption is unchanged, which matters in Miami-Dade because the school district millage is a meaningful share of a typical bill.
Put differently, Amendment 3 stacks on top of Save Our Homes rather than replacing it. The owners who will do the best out of this are the ones who buy a Miami homestead early, qualify as residents by December 31, 2026, let the Save Our Homes cap run on the assessment, and ride the higher exemption against a market value that keeps climbing. That is a compounding tax position, and it is why I am telling clients the 2026 to 2027 window is one of the best setups for a long-hold Miami primary home I have seen in years.
My Take From the Finance Side
I started my career in real estate finance in 2006 as a mortgage loan originator before I was ever showing homes, so my first instinct on any policy change is to run it through the monthly nut and the net cash flow. For Miami homestead buyers, the shift from $51,411 to $250,000 in exemption translates into a property tax reduction worth several hundred to a couple of thousand dollars a year on a typical Miami-Dade home, with the exact number driven by your city's millage rate. The Pinellas County Property Appraiser illustrated the shape of the change with a working case of roughly $1,203 in annual savings in 2027 and roughly $2,423 in 2028 at that county's 12.2011 non-school mill rate. Miami-Dade millages are not identical, but the direction is the same.
What that reduction actually lets a buyer do is buy more house for the same monthly cost, because escrow on an owner-occupied loan funds the tax bill. If you are shopping Miami in 2026 with a budget set against a 2026 tax load, re-run your numbers against the 2027 and 2028 load. It usually opens up a meaningful bracket, especially in Coral Gables, Pinecrest, and Coconut Grove, where tax bills on $1M to $3M homes are sizable. For the finance view on how to fold the exemption into a smart Miami purchase, my step-by-step Miami buying guide walks the whole process, and the broader market setup is in my 2026 Miami Real Estate Forecast.
For out-of-state buyers, the relocation sequence matters even more, and I cover the common traps in buying property in Miami as an out-of-state or international buyer.
Ready to Make Your Miami Move Count
Amendment 3 rewards early action and penalizes late movers. If you already own a Miami home, your 2026 job is to keep your homestead record clean. If you are relocating, your 2026 job is to lock down Florida residency before December 31. Either way, if you want a real conversation about how to position for 2027 and beyond, reach out and we can map the right plan for your situation.
