Amendment 3 Savings Calculator: Your 2027 and 2028 Florida Property Tax With and Without It

Compare your estimated 2026 property tax with 2027 and 2028 under current law and under Amendment 3, for a homestead or non-homestead property. The vote is November 3, 2026. Results are pending. These are estimates, not a prediction or a recommendation on how to vote.

Status: vote pending. Florida voters decide Amendment 3 (HJR 1F, 2026) on November 3, 2026. It needs at least 60% of the votes cast on the measure to pass. If it passes, it takes effect January 1, 2027. We will update this page after the results are known.

Estimate your property tax

Property type Market (just) value, 2026 ($) Assessed value, 2026 ($) County (fills in average millage) Non-school millage (mills) School millage (mills) Assumed market value growth (%/yr) Save Our Homes increase (%/yr, max 3) I did not have a permanent Florida residence on December 31, 2026 (new resident)

Find both values on your TRIM notice or your county property appraiser's website. Assessed value is lower than market value when Save Our Homes (homestead) or the non-homestead cap has held it down. If you just bought, they are the same. The county average millage is a starting point. Your actual rate depends on your city and special districts.

Example with the default inputs (a $400,000 homestead assessed at $300,000, Hillsborough average millage, 4% market growth): estimated total tax $5,024 in 2027 without Amendment 3 vs $3,790 with it, and $5,199 vs $2,714 in 2028. For a non-homestead property worth $500,000 (assessed $400,000) growing 7% a year, the 5% cap would lower the 2028 tax by about $538.

What the calculator assumes

2026 baseline = current law. 2026 homestead amounts: $25,000 off all levies, plus up to $26,411 off non-school levies on assessed value above $50,000 (Florida Department of Revenue). Those amounts are inflation-adjusted each year, so "without Amendment 3" for 2027 and 2028 is slightly understated.
With Amendment 3, homestead: the first $150,000 of assessed value is exempt from non-school levies in 2027 and $250,000 in 2028 (inflation-indexed from 2029, not modeled). The school exemption stays $25,000.
School levies are excluded. School taxes are the same with and without the amendment.
With Amendment 3, non-homestead: the cap on yearly increases in assessed value for non-school levies drops from 10% to 5% starting January 1, 2027. School levies use full market value.
New residents: if you did not have a permanent Florida residence on December 31, 2026, the non-school exemption is $50,000 until the fifth year of exemption. The calculator shows 2027 and 2028 only, so it does not reach year five.
Not modeled: other exemptions (senior, veteran, disability, portability), non-ad valorem assessments, changes in millage, sales or improvements, and the Legislature's and local governments' later choices (for example, local increases above the state minimum).

Frequently asked questions

When is the Amendment 3 vote and what does it need?

On November 3, 2026. Like every proposed amendment to the Florida Constitution, it needs at least 60% of the votes cast on the measure to pass (Article XI, Section 5(e)). If approved, it takes effect January 1, 2027.

Is this calculator a prediction of my bill?

No. It is an estimate under stated assumptions: your values grow at the rates you enter, millage rates stay where you set them, no sale or change of ownership happens, and no other exemptions (senior, veteran, disability) or non-ad valorem assessments are included. Local governments set millage each year and may change it.

Why is school tax the same with and without Amendment 3?

Amendment 3 changes the homestead exemption for non-school levies only. The school-levy exemption stays $25,000 and school taxes on non-homestead property are still based on full market value. The non-homestead cap change (10% to 5%) also applies to non-school levies only.

Who gets the $50,000 new-resident exemption?

According to the amendment text, a person who had not maintained a permanent residence in Florida as of December 31, 2026 receives a $25,000 school exemption and a $50,000 non-school exemption until the fifth year of exemption, then the full amount. The $50,000 figure is adjusted for inflation starting in 2028; this calculator holds it at $50,000.

How does the non-homestead 5% cap work here?

For property that is not a homestead, the assessed value for non-school levies can rise at most 10% a year today and at most 5% a year starting January 1, 2027 under Amendment 3, but never above market value. This tool starts from the assessed value you enter. A sale or change of ownership can reset the assessment to market value.
