Florida Amendment 3 Property Tax Bill: How a $400K Home's $6,248 School, County, and Special District Levies Break Down — and the $611/Year Appeal That Pays Off Either Way
You bought a $400,000 home in Florida last year. The bill that arrives around November 1 will say roughly $6,247.50. Meanwhile a mailer, a neighbor, and a TV ad all tell you Amendment 3 will "eliminate" your property tax. So what is on that bill, what would Amendment 3 actually touch, and what should you do in the five weeks before the November 3 vote?
I'm not here to tell you how to vote. I'm here to do what I did when I appealed my own assessment: take the bill apart line by line, then run the numbers on each scenario. The figures below use a composite Florida county with millage rates in a typical range. Swap in the rates from your own TRIM notice and the math works the same way.
What Amendment 3 Would and Wouldn't Do
According to the Institute on Taxation and Economic Policy's piece Tallying Up the Impact of Florida's Property Tax Ballot Measure on Local Communities, Amendment 3 would create a pathway for non-school property tax elimination. ITEP estimates that if it passes, local governments would lose $13.7 billion in the first two years alone.
Two details matter for your bill:
- It is a pathway, not a switch. What actually changes, and when, depends on follow-up legislation and local budget decisions.
- It targets non-school levies. School taxes are a separate line on your bill.
If you want your own neighborhood's numbers, two tools are now live. The Florida Policy Institute's Amendment 3 Local Funding Cuts Calculator is powered by ITEP. WLRN also covered the launch of the interactive search tool in Online Tool Shows Hidden Impact of Amendment 3 Property Tax Relief on Local Government Services. Both show how much funding your area's services could lose. Our post on Florida's 2026 ballot measure savings on a $500K home covers the statewide comparison. This post focuses on your line items.
Where Your $6,247.50 Goes: Line-by-Line Millage Breakdown
One mill is $1 of tax per $1,000 of taxable value. Florida's homestead exemption takes about $25,000 off the school taxable value and about $50,000 off the non-school taxable value. The second $25,000 is indexed to inflation, so your county's figure may be slightly higher. That gives our $400,000 home:
- School taxable value: $375,000
- Non-school taxable value: $350,000
| Levy | Millage | Taxable Value | Annual Tax | Share of Bill (rounded) |
|---|---|---|---|---|
| School (state required local effort + local) | 5.60 | $375,000 | $2,100.00 | 33.6% |
| County general fund | 4.50 | $350,000 | $1,575.00 | 25.2% |
| City / municipal | 4.00 | $350,000 | $1,400.00 | 22.4% |
| Fire rescue (MSTU or district) | 2.00 | $350,000 | $700.00 | 11.2% |
| Hospital / children's services district | 0.75 | $350,000 | $262.50 | 4.2% |
| Library district | 0.40 | $350,000 | $140.00 | 2.2% |
| Water management district | 0.20 | $350,000 | $70.00 | 1.1% |
| Total | 17.45 | $6,247.50 | 100% |
The key split is this: $2,100 (33.6%) is school tax, and $4,147.50 (66.4%) is non-school. Non-school levies are the ones Amendment 3 would open the door to eliminating. If you live in an unincorporated area, the city line is replaced by county municipal-services charges. You can see the same stack-up pattern in our Florida millage breakdown for school, county, and special district levies.
This is the kind of analysis Tavirex runs for you, so you don't have to build the spreadsheet yourself.
"Why Is My Effective Rate Different From My Millage Rate?"
This is the question I get most from friends. The nominal rate is the millage: 17.45 mills, or 1.745% of taxable value. The effective rate is what you actually pay divided by what the house is worth:
$6,247.50 ÷ $400,000 = 1.56%
The effective rate is lower than the nominal rate because of the homestead exemption. Now take the same house with a long-time owner. Say they bought in 2016, and Save Our Homes (Florida's cap on homestead assessment growth) has held the assessed value to $290,000:
| New Buyer (assessed at $400K) | 2016 Owner (capped at $290K) | |
|---|---|---|
| School tax ($5.60 mills × $265K) | $2,100.00 | $1,484.00 |
| Non-school tax (11.85 mills × $240K) | $4,147.50 | $2,844.00 |
| Total bill | $6,247.50 | $4,328.00 |
| Effective rate on $400K market value | 1.56% | 1.08% |
Same house, same millage, same street. The new buyer pays $1,919.50 more per year. That is why our tax_foundation_rates dataset (255 rows) shows Florida's statewide effective rate under 1%, far below New Jersey's 2.23%, even though many Florida counties levy 15 to 20 mills. Long-tenured owners pull the average down. If you bought after the cap reset, you aren't paying "Florida's rate." You're paying the rate for a new buyer. Our deadline post on buying before January 1 explains how that timing shows up on the bill.
Amendment 3 Scenarios on Your Bill
Here is the new-buyer bill under three simple scenarios. The "replacement share" is the portion of lost local revenue you end up paying back through fees, sales taxes, or special assessments.
| Scenario | Annual Bill | Change | Effective Rate |
|---|---|---|---|
| Today | $6,247.50 | n/a | 1.56% |
| Non-school levies eliminated, 25% replaced through other charges | $5,210.63 | −$1,036.87 | 1.30% |
| Non-school levies eliminated, 50% replaced | $4,173.75 | −$2,073.75 | 1.04% |
| Non-school levies eliminated, 0% replaced (upper bound) | $2,100.00 | −$4,147.50 | 0.53% |
The first two rows are my own illustrative scenarios, not forecasts. The 0% row is the ceiling, and it assumes the services those levies pay for (fire rescue, libraries, county and city operations) keep running without replacement revenue, which is unlikely.
For a sense of scale, ITEP's $13.7 billion over two years works out to about $6.85 billion per year. Divide that across Florida's roughly 8.6 million households (Census ACS) and you get about $800 per household per year in local funding at stake. That is back-of-envelope math, not a tax bill. The actual burden would fall unevenly, which is why the FPI calculator matters. A county with a big non-school share and thin commercial base sits at a different spot on this table than a county with hotels, ports, and big-box retail.
The Part That Doesn't Change: Your Assessment Still Sets Your Bill
Whatever happens on November 3, school taxes remain, and every levy that survives is multiplied by your taxable value. That makes your assessed value the one variable you control. Here is an appeal model using comparable sales, the same skill assessors and appraisers use.
Step 1: Pull three recent comparable sales. Choose homes within a mile or so, similar size and age, sold within 12 months of January 1 (Florida's valuation date):
| Comp | Sale Price | Adjustment | Adjusted Value |
|---|---|---|---|
| A (1,900 sq ft) | $372,000 | −$4,000 for larger size | $368,000 |
| B (1,800 sq ft) | $358,000 | +$6,000 for size and updated roof | $364,000 |
| C (1,850 sq ft) | $371,000 | −$8,000 for pool | $363,000 |
| Average | $365,000 |
Step 2: Compute your assessment ratio. $400,000 ÷ $365,000 = 109.6%. The IAAO's ratio study standard treats a jurisdiction's median ratio between 0.90 and 1.10 as acceptable. You can be "in tolerance" as a group and still be over-assessed on your own house. It's the same gap our iaao_reassessment and lincoln_institute_ratios datasets (51 state rows each) help us flag.
One Florida-specific caution: property appraisers may adjust for typical selling costs when setting just value. Ask your appraiser what adjustment they used and compare against their figures, not raw sale prices alone.
Step 3: Price the stakes. The $35,000 reduction applies to both school and non-school taxable value:
- Annual savings today: $35,000 × 17.45 mills = $610.75/year
- If non-school levies were eliminated: $35,000 × 5.60 mills = $196/year
Now the present value over a 10-year ownership period at a 5% discount rate. The annuity factor is (1 − 1.05⁻¹⁰) ÷ 0.05 = 7.7217.
| Scenario | Annual Savings | 10-Year Undiscounted | 10-Year Present Value |
|---|---|---|---|
| Status quo millage | $610.75 | $6,107.50 | $4,716 |
| School-only bill | $196.00 | $1,960.00 | $1,513 |
An appeal for a homestead also lowers your assessed-value base going forward, so the reduction carries into future cap calculations. The takeaway: if you're going to appeal, appeal now. The savings are largest while the non-school levies still exist. NTUF's published appeal figures, which we track in our ntuf_appeal_stats dataset, generally put success rates somewhere between roughly 30% and 60% depending on jurisdiction, while only a small fraction of owners ever file. Our full walkthrough of winning a Florida VAB hearing with comparable sales evidence covers the hearing itself.
You can model this for your specific situation at Tavirex, using your own assessed value, comps, and millage stack.
Deadlines: What You Can Still Do Before and After November 3
Today is September 30, so here is the honest calendar:
- Value Adjustment Board petition: Due 25 days after the TRIM notice was mailed in August, which for most counties was in September. If you missed it, call your county VAB clerk and ask whether a late filing for good cause is possible. Otherwise, mark August 2027 for the next TRIM notice.
- Pay in November: Florida offers a 4% discount for paying in November (3% in December, 2% in January, 1% in February). On our example's ad valorem total, 4% of $6,247.50 is $249.90. That is a guaranteed return before any appeal.
- Confirm your homestead: Check the property appraiser's website to confirm the exemption is on your parcel. The application deadline is March 1.
- Check the FPI calculator: Enter your address to see which local services your area's non-school levies fund.
Everything here is general education, not legal advice, and appeal rules vary by county. The petition form and evidence rules are on your county's VAB page.
The Bigger Picture: Comparing Whole Systems, Not One Rate
Two of the source pieces remind us that tax burdens are systems, not single numbers. The Tax Foundation's 2026 Spanish Regional Tax Competitiveness Index exists because taxpayers and policymakers need to compare regions across the whole tax system. Looking only at one rate misleads, and that is exactly the mistake when someone says "Florida has low property taxes" without asking who you are and when you bought.
The Tax Foundation's Why Expensing New Rental Housing Is One of the Best Ways to Tackle the Housing Supply Problem describes the Rental Housing Investment Act, which would let developers deduct up to $150,000 of cost per unit immediately. That is a federal income tax change. It does nothing to a county tax bill. If you own a rental in Florida, you have no homestead exemption and no Save Our Homes cap. You get a 10% non-homestead assessment cap instead, and your property tax is a significant operating expense that gets passed through to rents. Everything in the appeal section applies to you too, and arguably matters more.
Your Action Plan
- Pull your TRIM notice and copy every millage line into the table format above.
- Compute your effective rate (total bill ÷ market value). If it's well above the roughly 1% statewide figure, find out whether you're a new buyer, a missing exemption, or over-assessed.
- Run the FPI calculator to see your area's exposure to Amendment 3.
- Build a three-comp appeal file now, while the sales data is fresh, and calendar August 2027.
- Pay in November for the 4% discount.
Whether Amendment 3 passes or fails, the homeowner who understands their bill line by line is in a stronger position than the one who only knows the total. If you want to run your own numbers, compare your millage stack against other counties, and see what an assessment reduction is worth to you, start at Tavirex's comparison tool.
