All Florida countiesBased on the 2026 certified tax roll and 2025 tax ratesFlorida voters approved Amendment 3 on Nov. 3, 2026. It raises the homestead exemption for every property tax except school taxes to $150,000 in 2027 and $250,000 in 2028. That means county taxes everywhere in St. Lucie County, plus city taxes for homes inside city limits. Search for a property to see an estimate.
These estimates use current numbers. Amendment 3 will usher in substantial changes to how local governments must tax in order to provide essential services. This tool shows only what the change means based on 2026 values and 2025 tax rates. Non-ad valorem assessments, such as fire, solid waste and stormwater fees, are likely to rise to make up for budget shortfalls, and they are not included here.
Illustrative estimates only. The figures on this site are meant to illustrate how Amendment 3 could work based on current data. They are not official. For official information about budgets, tax rates and revenue, contact your city, town or St. Lucie County government directly.

How many of the county's 192,432 parcels, including 106,336 with a homestead exemption, would owe no property tax other than school taxes. That means no county tax, and no city tax for property inside city limits.

Non-ad valorem assessments, such as fire, solid waste and stormwater charges, are not included. Figures are gross levies, before early-payment discounts of up to 4% and unpaid taxes; Florida law requires taxing authorities to budget at least 95% of their ad valorem proceeds. Estimated non-school ad valorem taxes on the roll if every taxing authority kept its 2025 rate. Assessed values of homesteads rise by up to 3% a year, never above just value; other property is held at 2026 values. In practice, local governments will set new rates each year.

Districts that cover the whole county levy on the same taxable value as St. Lucie County government's countywide levies, so their estimated percentage changes match; districts that cover only part of the county can differ. Each page lists the full limitations.
Estimated city ad valorem revenue at each city's or town's 2025 tax rate, before and after the new homestead exemption. Homestead assessed values rise by up to 3% a year (never above each home's just value); other property stays at 2026 values. These are estimates only: values, the number of homesteads and tax rates will change, and property taxes are one of several revenue sources. Each page lists the full limitations.
The size of the estimated change depends mostly on how much of each place's taxable value comes from homesteads. In 2026 that share ranges from 21.9% in Fort Pierce to 54.0% in Port St. Lucie. Lower home values also play a part, because a flat exemption removes a larger share of a lower-valued home's taxable value.
| City or town | City millage | Homesteads | Homestead share of taxable value | 2026 city revenue (95%) | 2028 estimate (95%) | Change | Percent change |
|---|---|---|---|---|---|---|---|
| City of Fort Pierce | 6.9000 | 8,504 | 21.9% | $31,544,727 | $26,229,517 | −$5,315,210 | −16.8% |
| City of Port St. Lucie | 4.6607 | 75,095 | 54.0% | $116,234,433 | $70,213,851 | −$46,020,583 | −39.6% |
| Town of St. Lucie Village | 2.0000 | 185 | 42.3% | $233,447 | $186,256 | −$47,191 | −20.2% |
Revenue is shown on a budget basis: 95% of the gross levy (taxable value times the city tax rate). Florida law requires taxing authorities to plan on at least 95% of ad valorem proceeds, which allows for early-payment discounts of up to 4% and for unpaid taxes. Percent changes are the same on either basis. Compare cities and towns side by side.
