Buying a Florida Home Before December 31, 2026? What Amendment 3 Could Mean for Your Timing

With Florida voters deciding Amendment 3 on November 3, 2026, some real estate professionals are warning buyers not to wait: if the measure passes, the difference between establishing permanent Florida residency by December 31, 2026 and arriving later could decide how much of the new tax break you actually get — and for how many years. (Treasure Coast Today, October 16, 2026)

Here's what the measure would do, who the December 31 deadline actually applies to, and why the timing decision is more nuanced than the headlines make it sound.

What Amendment 3 would change

If approved by at least 60% of voters, Amendment 3 would:

• Raise the homestead exemption on non-school property taxes from today's levels to $150,000 in 2027 and $250,000 in 2028, with inflation adjustments starting in 2029. The change takes effect January 1, 2027.
• Cut the annual cap on assessment increases for non-homestead property (rentals, second homes, commercial) from 10% to 5%.
• Leave school district taxes untouched — the bigger exemption applies to non-school levies only.

Florida Realtors, the main backer of the yes campaign (reported $18 million in contributions to Vote Yes on 3), says the measure would save the average homeowner about $1,000 in 2027 and $1,800 in 2028. That estimate comes from the campaign, so treat it as the favorable case, not the guaranteed outcome — your actual savings depend on your home's assessed value, local millage rates, and how assessments move.

The December 31 deadline, explained

This is the detail driving the buyer-rush warnings. Under the proposal as written:

• Establish permanent Florida residency by December 31, 2026, and you fall into the existing-resident group entitled to the full phased benefit as it rolls out in 2027–2028. You must still meet the ownership, January 1 residency, and homestead filing requirements for the first eligible homestead year.
• Arrive on or after January 1, 2027, and you'd initially receive a $50,000 non-school exemption when eligible — the larger exemption only kicks in after several years of homestead exemption (the fifth year under the proposal), subject to implementation.

One important nuance the rush headlines skip: the cutoff is about when you establish permanent Florida residency, not necessarily when you close on the house. A person who becomes a permanent Florida resident by December 31, 2026 can be in the existing-resident group even if they buy later. That's why agents are telling relocating buyers to get their residency paperwork — driver's license, voter registration, homestead filing — sorted before year-end, not just their closing date.

The counterargument buyers should hear

Amendment 3 is polling below the 60% threshold it needs in most surveys: Stetson 51%, EDGE/MDW Communications 50%, Associated Industries of Florida 53%, Mason-Dixon 55%, a Broward Sun-Sentinel poll 53% — and the most recent, a University of North Florida poll of likely voters (Oct. 12–19), has support at just 50% with 14% undecided. The one survey above the line — James Madison Institute/Targoz at 63% of likely voters — is an outlier, and the undecided bloc will decide it.

And even if it passes, economists warn the savings may partly flow into prices rather than pockets: a Realtor.com economists' model found that cutting recurring property costs gets capitalized into home values, with a 7%–9% immediate rise in Florida home values in the hypothetical full-elimination scenario. Amendment 3 is a partial cut, not full elimination, so the real effect would be smaller — but it's the reason some buyers are skeptical that tax savings and lower purchase prices can coexist.

On the other side of the ledger, the state's Revenue Estimating Conference projects the measure would cut local non-school property tax revenue by roughly $5 billion in its first year and about $11.8 billion annually once fully phased in. Counties and cities would have to absorb that through spending changes, fee increases, or both — something to watch if you're buying in a fast-growing county banking on that revenue.

What to do before you vote or buy

1. Check your homestead status now. Look up your parcel on your county property appraiser's site and confirm which exemptions you hold today.
2. Know your early-voting window. Early voting is mandatory statewide October 24–31, but several counties (Broward, Indian River, and others) start October 19. The deadline to request a vote-by-mail ballot is October 22 at 5:00 p.m. local time; completed ballots must reach your Supervisor of Elections by 7:00 p.m. on Election Day, November 3.
3. Don't confuse the vote with your tax bill. Your 2026 tax bill mails in late October and is payable November 1 — under current law, regardless of the vote. Pay it on the normal schedule and take the early-payment discount if you can.
4. If you're relocating to Florida: talk to a Florida tax adviser about the residency cutoff before assuming a late-2026 move locks in the full benefit.
