Ballot Measure Explainer · Florida Amendment 3

See what Amendment 3 could mean for your property tax bill.

A plain-number look at how the proposed homestead exemption increase compares to what you pay today, using your own assessed value and millage rate.

On the ballot: Nov 3, 2026 Requires 60% voter approval If passed, starts Jan 1, 2027
What changes

The homestead exemption on non-school taxes rises from about $50,000 today to $150,000 in 2027 and $250,000 in 2028.

What stays the same

School taxes are untouched. Your Save Our Homes assessment cap and portability still work exactly as before.

Who qualifies

Homestead property only. Florida residents as of Dec 31, 2026 get the full increase right away; newer residents phase in over 5 years.

The trade-off

Counties and cities lose billions in revenue, which may show up later as higher millage rates or new fees.

How to use this calculator

A short walkthrough of the calculator, if you'd rather watch than read.

Where to find these numbers

You don't need to guess, every number the calculator asks for is already sitting in your mailbox. You will need your Notice of Proposed Property Taxes or TRIM notice. Your property appraiser mailed this to you in mid-August. It's stamped "DO NOT PAY: THIS IS NOT A BILL" in the corner. The example shown below is what Hillsborough County sends out, Pinellas, Pasco, Hernando counties may look a little different. This is not asking for money, it's disclosing next year's proposed rates before the taxing authorities finalize them at public hearings.

In a CDD community? Your TRIM notice only covers ad valorem taxes (the millage rates below). CDD fees and other non-ad valorem assessments are billed separately and won't appear on this notice or in the ad valorem estimate this calculator produces. If you know your CDD amount, you can add it in the bill estimator below so your estimate reflects your full bill. If you don't, check last year's tax bill on your county tax collector's site or your CDD's own assessment roll.
Annotated Hillsborough County Notice of Proposed Property Taxes with the Assessed Value row and school and non-school millage rates circled

A real Hillsborough County notice, with account details redacted. The circled amounts are exactly what to enter above: green for Assessed Value, blue for school millage, orange for non-school millage.

  1. 1
    Find "Assessed Value" in the value table. Near the bottom of page one is a table called "Property Appraiser Value Information." It's not the "Market Value" row at the top of that same table. Scroll down past the Save Our Homes Cap line to "Assessed Value." This figure is in the green square in the sample above. It's usually the same figure in every column (County, Public Schools, Municipal, Other), so any one of them works.
  2. 2
    Add up the millage rates, two ways. Above the value table is the "Taxing Authority Tax Information" table, listing each authority with its own rate across a few columns. Add together the two rows under "Public Schools" (School-State + School-Local in the blue square in the sample above) for your school millage. Then, add together every other row: County, Municipal, Water Management, and any special districts (red circles in the sample above), for your non-school millage. Using the rightmost column ("your tax rate this year if proposed budget change is made") gives the closest read on where rates are actually headed. You can use the Millage Rate Calculator below or the calculator function on your computer.
  3. 3
    No notice handy? Look it up online. Your county property appraiser's website has a free property search where you can pull up a parcel by address and see the same assessed value and exemption details. Quick links for our area are below.

Add up your millage rates

If adding a column of rates in your head sounds error-prone, type each line from your notice below and let this do the adding.

School lines

Red circles on your notice
Non-school subtotal: 0.000 mills

Estimate your bill

Pull your numbers from your most recent TRIM notice (mailed in August). This tool holds your assessed value flat across years so you can isolate the effect of the amendment itself; it won't predict future market appreciation.

Not on your TRIM notice. Check last year's tax bill on your county tax collector's site, or your CDD's assessment roll. Added on top of the estimate below and unaffected by Amendment 3.
This affects how quickly you'd receive the larger exemption.
Total millage entered: 0.000 mills  ·  add up every rate in the taxing authority table and this should match.
Not calculated above: Amendment 3 also lowers the annual assessment-increase cap on non-homestead property (second homes, rentals, commercial) from 10% to 5% per year. That doesn't change this year's bill directly; it slows how fast future assessments, and therefore future tax bills, can climb on those properties.
This is an educational estimate, not a tax bill or professional advice. Actual amounts depend on your county property appraiser's final assessment, exact millage rates set each year by local taxing authorities, and whether Amendment 3 is approved by at least 60% of Florida voters on November 3, 2026. Figures assume your Save Our Homes assessed value stays constant for comparison purposes only. Non-ad valorem assessments such as CDD fees, if entered, are held flat across all years shown and are not affected by Amendment 3 or the Save Our Homes cap. For your exact numbers, check your TRIM notice or contact your county property appraiser's office.
