If you're closing on a home in Sarasota County this fall, you've probably heard that Florida voters are deciding a major property tax change on November 3. What you may not have heard is that the vote itself may not be the date that determines your tax bill. A separate deadline, buried inside the amendment's own text, could matter more to your bottom line than how the state votes.
That deadline is December 31, 2026. And it has nothing to do with polling.
What Amendment 3 Would Actually Do
Florida's Legislature passed the measure known as Amendment 3, or CS/HJR 1-F, during a special session held June 1 through 3, 2026. The vote wasn't close on paper: 75-26 in the House, 30-9 in the Senate. Lawmakers filed it with the Secretary of State on June 16, sending it to the November 3 general election ballot, where it needs 60 percent approval to become law. That threshold is worth sitting with for a second. No presidential candidate has cleared 60 percent in Florida in modern history, and even Florida's 2024 abortion rights amendment, which drew broad bipartisan sympathy, landed at 57 percent and failed.
If it does pass, the mechanics are straightforward on the surface. Today's homestead exemption for the 2026 tax year sits at $51,411, split between a $25,000 exemption that applies to all millages, including school taxes, and an additional $26,411 CPI-adjusted exemption that applies only to non-school millages. Amendment 3 would replace the non-school portion with a much larger exemption: up to $150,000 starting in 2027, and $250,000 starting in 2028, indexed to inflation after that. School taxes stay untouched either way.
None of this touches your 2026 tax bill. Even if voters approve it in November, the change first shows up on the August 2027 TRIM notices and the tax bills mailed that November. If you're closing before year-end, your near-term tax picture doesn't move regardless of the outcome.
The Second Clock: Establishing Residency Before December 31
Here's the part that gets lost in the coverage of the vote count and the 60 percent threshold. Amendment 3 doesn't treat every future homesteader the same. It draws a hard line at December 31, 2026.
Homeowners who establish Florida permanent residency by that date qualify for the full expanded exemption once they buy a home and file for homestead, no waiting period attached. Miss that date, and a different rule kicks in. Anyone who establishes Florida residency on or after January 1, 2027 starts as a "new resident" under the amendment's own language, receiving the smaller current-style exemption, roughly the existing $50,000 structure adjusted by CPI, applied only to the first $50,000 of assessed value for non-school taxes. That reduced exemption holds for four full years. Only in year five does the new resident become eligible for the larger amount.
Pinellas County's property appraiser laid out exactly this mechanic in a public FAQ on the amendment, and because this is a state constitutional change, the same rule governs every Florida homestead, Sarasota County included. There's a genuine gray area here too. Florida Policy Project's analysis flagged that the resolution never defines what "establishing residency" means for someone who doesn't yet own property. A renter with a Florida driver's license and voter registration might still fall into the new-resident penalty tier unless they close on a home before the calendar turns.
| If you establish Florida residency... | Exemption path once you file homestead |
|---|---|
| By December 31, 2026 | Full expanded exemption ($150,000 in 2027, $250,000 in 2028) with no waiting period |
| On or after January 1, 2027 | Current-style exemption (~$50,000, non-school only) for four years, larger exemption begins year five |
For anyone weighing whether to close in December versus waiting until January, that table is the whole decision in miniature.
The Deadline You Already Had, Stacked on Top of the New One
Amendment 3's residency cutoff doesn't replace Florida's existing homestead rules. It stacks on top of them.
Florida has always required that you own and occupy a home as your permanent residence as of January 1 of a given tax year before you can claim homestead for that year. The filing deadline is typically March 1. Buy and move in on January 15, and you're not eligible for homestead until the following tax year, no matter what the amendment does.
Put both clocks together and the timing gets specific fast:
- Close in September or October 2026. You establish residency well before the cutoff. You still won't get homestead until tax year 2027, since you'll own the home before January 1, but when you file by March 1, 2027, you'll be positioned for the full expanded exemption if voters approve it.
- Close in December 2026. Same result, as long as you've moved in and made Florida your permanent residence before the ball drops. Cutting it close raises the documentation stakes, since the property appraiser will eventually ask for proof tied to that date, such as a Florida driver's license, voter registration, or utility bills.
- Close in January 2027 or later. You've missed the residency cutoff entirely. Even with a favorable vote, you'd be classified as a new resident under the amendment and locked into the smaller exemption for four years before the bigger number applies to you.
None of this changes if you're already a longtime Florida homeowner moving within the state. Portability, the ability to transfer your accumulated Save Our Homes benefit to a new Sarasota homestead using Form DR-501T, isn't touched by Amendment 3 at all. If you already have Florida residency established, this timing question doesn't apply to you the same way it applies to someone relocating from out of state this fall.
If You're Buying Investment Property or a Second Home
None of the exemption expansion applies if the property won't be your permanent residence. Amendment 3 does include one provision that touches non-homesteaded property: the annual assessment growth cap for rentals, vacation homes, and commercial property would drop from 10 percent to 5 percent starting January 1, 2027, if voters approve it. That's a real change for anyone holding investment property long-term, since it slows how fast taxable value can climb in a strong appreciation year. But it comes with no expanded exemption attached, and the residency-date mechanics above simply don't apply to a property you won't be living in.
What Happens If Voters Say No
Given the 60 percent bar, a no vote is a real possibility, and it's worth planning for both outcomes rather than assuming passage. If the amendment fails, nothing changes. The current $51,411 exemption structure stays in place, the Save Our Homes cap continues limiting annual assessment increases to the lesser of 3 percent or CPI (set at 2.7 percent for 2026), and the residency cutoff becomes irrelevant because there's no new exemption tier to qualify for. Property tax planning reverts to exactly what it's always been in Sarasota County.
There's also a pending legal wrinkle. A lawsuit filed in Leon County in June challenges whether the ballot title and summary, including language like "Save Our Homes From Excessive Property Taxes," describe the measure neutrally rather than advocating for it. That case was still pending as of late July, and a court-ordered rewrite of the ballot language remains possible before November.
What Sarasota County Says Is On the Line
Sarasota County officials aren't neutral observers here. County staff have projected the county could lose up to $87 million in property tax revenue by fiscal year 2029 if voters approve the expanded exemption. Officials named specific programs they expect to feel the pressure: emergency medical services, Legacy Trail extensions, the environmentally sensitive lands protection program, mosquito control, navigable waterways maintenance, and several local light districts. Whatever your position on the ballot measure, that's the tradeoff being put in front of Sarasota voters this November, framed in terms of the county's own budget rather than abstractions about state tax policy.
A Few Questions Worth Settling Before You Close
Does Amendment 3 change my 2026 tax bill either way? No. Even with voter approval, the new exemption first applies to the 2027 tax year, appearing on TRIM notices mailed in August 2027 and tax bills sent that November.
If I already own a Florida homestead and I'm just relocating within the state, does the residency cutoff apply to me? No. That provision targets people establishing Florida residency for the first time. If you already have an existing Florida homestead, your portability rights under Form DR-501T carry over regardless of how the vote goes.
What if I'm not sure my closing date will land before December 31? Given the ambiguity in how the amendment defines "establishing residency" for someone who doesn't yet own a home, this is worth confirming directly with the Sarasota County Property Appraiser's office or a qualified tax professional before you finalize a closing date.
