Amendment 3 and a St. Lucie West Tax Bill: What It Reaches

Most coverage of Amendment 3 leads with $150,000 and $250,000. For a family relocating to St. Lucie West, a different number in the ballot summary may matter more: December 31, 2026. Under the measure's own language, people who are not Florida residents on that date would get the existing homestead exemption when they qualify. The increased exemption would begin only "with the fifth year of exemption."

Voters decide on November 3, 2026, about three weeks from now. For a buyer here, the amendment's value depends on two things the headlines mostly skip. The first is when that buyer became a Florida resident. The second is which lines of a St. Lucie West tax bill the exemption can reach in the first place.

The residency line written into the ballot

Here is the full sentence from the summary posted by the Florida Division of Elections, which lists the measure as active:

Persons who are not Florida residents on December 31, 2026, will receive the existing homestead exemption upon qualifying for a homestead exemption, with the increased homestead exemption beginning with the fifth year of exemption, to the extent permitted by the U.S. Constitution.

That wording comes from a revised version. On August 13, 2026, Attorney General James Uthmeier released a new ballot title and summary after a Leon County Circuit Court ruling found parts of the original language misleading and inaccurate. According to the Florida Chamber of Commerce, the amendment itself did not change. Only the description voters will read changed.

The Florida House bill analysis for HJR 1F defines permanent residence as a person's true, fixed, permanent home and principal establishment. It says the property appraiser decides each case on its facts, looking at factors such as:

• Declaration of domicile filings
• Voter registration
• Vehicle registration and driver's license
• Place of employment
• Where children attend school
• The address on tax returns
• Utility payments

Residency is one thing. Homestead is a separate test: it requires legal or beneficial title and making the property a permanent residence as of January 1. A September 2026 explainer from the law firm Bilzin Sumberg makes the same distinction. It says that if the amendment passes, new residents would start with an exemption of up to $50,000 of assessed value for non-school levies. They would become eligible for the larger exemption in their fifth year. Bilzin presents its timing points as its own reading of the amendment, not as agency guidance.

This is where a relocation timeline and a closing date can work against each other. The amendment ties the increased exemption to when a person became a Florida resident, and the homestead exemption is tied to the property. A buyer who closes on a St. Lucie West home in February 2027 is in a different position from one who had already set up Florida residency before the year ended, even if the two houses sit side by side. Whether that difference turns out to be large depends on the next question.

What the exemption can reach on a St. Lucie West bill

The increased exemption covers only non-school taxes. The House analysis says the changes apply to county, municipal and special-district levies but not to school-district levies. The constitutional text also says the exemption does not cover assessments for special benefits.

That limit matters in St. Lucie West, where the St. Lucie West Services District levies its own charges. SLWSD's two yearly assessments are non-ad valorem charges that appear on the annual property-tax bill, separate from its monthly water bill. They pay for stormwater systems, retention ponds, wetlands, preserves and rights-of-way.

Here is how each part of the bill lines up against the amendment:

The St. Lucie County Property Appraiser's 2026 TRIM insert says this directly: school taxes stay at the $25,000 exemption, and special assessments such as solid waste, CDDs and stormwater stay alongside them.

The city's share of the bill is smaller than many owners assume. The City of Port St. Lucie says about 22% of a resident's total property-tax bill goes to the City. The other 78% goes to countywide and regional agencies. The city rate is also already falling. On September 28, City Council adopted the FY 2026-27 budget and cut the millage from 4.9750 to 4.8750, the 11th straight annual reduction, for the fiscal year that began October 1.

A St. Lucie West bill therefore has a fixed core of school taxes and SLWSD assessments that Amendment 3 would not touch, for longtime residents or newcomers. The amendment works on the remaining ad valorem lines. For a buyer on the wrong side of December 31, even that part would be limited to the existing exemption until year five.

Why the county line is the one to watch

The ad valorem lines the amendment does reach are mostly county lines, and St. Lucie County government is more exposed than any other county in Florida. TCPalm reported in July that the county is projected to lose $63 million in revenue in the first year and $105 million in the second if the amendment passes. In the same TCPalm report, Cragin Mosteller, deputy executive director of the Florida Association of Counties, said: "They (St. Lucie County) are No. 1 when it comes to the impact of the amendment."

The city's estimate is smaller but still large. Port St. Lucie projects a $26.3 million revenue loss in the first year and another $22.1 million in the second, for $48.4 million over two years. In January, before the final amendment language existed, County Administrator George Landry told WQCS that property taxes funded roughly 40% to 50% of the county budget. He said staff were looking for ways to reduce the budget while limiting the effect on services.

The amendment also limits how that revenue can be spent. Counties and municipalities could use property taxes only for public safety, education and schools, infrastructure, natural resources, bond debt service, employee retirement benefits, and operations and administration. Other spending would need approval from county officers or local governing bodies. It would also create a path to go further. The Legislature would set a uniform procedure for counties and cities to raise the homestead exemption up to full assessed value, and special districts could do the same with referendum approval.

For anyone comparing neighborhoods, this means much of the benefit falls on the county ad valorem lines, and the county is the government facing the biggest revenue gap in the state. How that gap gets handled is not yet known.

Whether it passes at all

Amendment 3 needs 60% of the people who vote on the measure, according to the House analysis. Recent polls disagree on how close it is:

1. St. Pete Polls for Florida Politics, October 5 to 7, 2026: 42% support, 35% oppose, 23% undecided. The survey covered 836 likely voters with a margin of error of plus or minus 3.4 points.
2. Mason-Dixon, as summarized in the same report: 55% support, 26% oppose, 19% undecided.
3. Stetson, as summarized in the same report: 51% support, 25% oppose, 24% undecided.

The Florida Politics report carrying those numbers is dated October 8. The polls used different methods, so they don't form a single trend line. An August James Madison Institute poll, also reported by Florida Politics, found 76% support among likely voters when no tradeoffs were mentioned. Support fell to 55% after respondents heard about possible local service cuts or replacement funding.

None of these polls shows the measure at 60%. So the December 31 residency line is something to understand now, not a deadline anyone has confirmed will apply.

Questions buyers are raising

Does the residency cutoff apply to someone already living in Florida who buys a new home in St. Lucie West? The ballot language turns on whether a person was a Florida resident on December 31, 2026, not on when they bought a particular house. The House analysis does not say how the cutoff applies to a Floridian moving from one home to another. No authoritative interpretation of that scenario turned up in our research.

Has anyone challenged the residency provision in court? The court ruling reported so far was about the ballot title and summary wording, which was rewritten in August. The ballot summary says the delayed phase-in applies "to the extent permitted by the U.S. Constitution."

What changes for a second home or rental in St. Lucie West? Non-homestead property doesn't get the homestead exemption. Under the amendment, the yearly cap on assessment increases for non-homestead property would drop from 10% to 5%.

When would any of it take effect? The amendment takes effect January 1, 2027. The $150,000 exemption begins in 2027, the $250,000 exemption in 2028, and inflation adjustments start January 1, 2029.
