⚡ Quick Answer
Florida property tax has one rule that catches almost every buyer: your taxes reset when you buy. The low tax figure on a listing is the seller's bill, held down for years by the Save Our Homes cap. That cap doesn't transfer. When the home sells, the assessed value resets to roughly what you paid — so your first-year bill can be hundreds or thousands of dollars higher than the listing suggested.
Two things explain the whole system. The Homestead Exemption knocks up to $50,000 off the taxable value of your primary residence and unlocks the cap. Save Our Homes then limits assessed-value growth to 3% or inflation, whichever is lower, every year you stay. File by March 1 — it isn't automatic.
✅ Key Takeaways
- The formula: (assessed value − exemptions) × millage rate = your bill. Everything else is detail
- Homestead Exemption: up to $50,000 off your primary residence's taxable value — and it's the key that unlocks Save Our Homes
- Save Our Homes: caps assessed-value increases at 3% or CPI, whichever is lower. Over years, a large gap opens between market value and taxable value
- The reset trap: that gap dies with the sale. Never budget off the seller's tax line — budget off your purchase price
- Portability: repeat buyers can carry up to $500,000 of accumulated savings to the next Florida homestead (Form DR-501T, within 3 tax years)
- March 1 deadline: Homestead isn't automatic. Miss the date and you wait a full year
📋 TL;DR
The formula: (assessed value − exemptions) × millage = your bill. The exemption: Homestead takes up to $50,000 off your primary residence (first $25K applies to all taxes; second $25K is non-school and inflation-indexed, $25,722 for the 2025 tax year). The shield: Save Our Homes caps assessed growth at 3% or CPI, whichever is lower. The trap: it all resets to your purchase price when you buy. The deadline: file by March 1. The move: estimate off your purchase price in the → Florida Mortgage Calculator.

👤 Who This Guide Is For
- Florida buyers trying to predict a real tax bill before they make an offer
- New Florida homeowners who just got a bill far higher than the listing showed
- Anyone who has never filed for Homestead — and may be leaving thousands on the table
- Repeat Florida buyers who don't know portability exists
- Investors and second-home buyers who need to know what they don't get
Browsing Florida listings and loving the low property tax history on a home you like?
Don't fall for it.
Here's the rule that catches almost every Florida buyer off guard:
The low tax bill on the listing is not the tax bill you'll pay. When you buy, your taxes reset — often to a much higher number.
But once you understand two things — the Homestead Exemption and the Save Our Homes cap — Florida property tax stops being a mystery.
I'm going to show you exactly how to predict your real bill, avoid the reset surprise, and save thousands over the years you own.
Follow along with your own numbers: plug your purchase price and county tax rate into the Florida Mortgage Calculator as you read, so the payment you see is the payment you'll actually make.
1. The "Big 3" Property Tax Formula
Your annual property tax boils down to one simple formula.
Let's break it down:
| Term | What it actually means |
|---|---|
| Assessed value | What the county property appraiser says your home is worth for tax purposes. For a homesteaded home, its growth is capped each year — see Save Our Homes |
| Exemptions | Amounts subtracted from assessed value before tax is calculated. The Homestead Exemption is the big one |
| Millage rate | The local tax rate, quoted in "mills." One mill = $1 per $1,000 of taxable value. Set by counties, cities, school districts and special districts, so it varies by location — commonly mid-teens in mills, or roughly 1%–2% of value |
Florida has no state income tax, and its statewide effective property tax rate is around 0.8% of home value — close to the U.S. average.
⚠️ Why 0.8% Isn't Your Number
That 0.8% statewide figure is an average across every Florida home — and most of them belong to long-time owners whose assessed values have been held down for years by Save Our Homes. It's a real statistic that describes a population you're not in yet.
As a new buyer, you reset to full market value, so your first-year bill runs much closer to the raw millage rate on what you paid — commonly 1%–2%. That's why our city guides quote roughly 1.4%–1.6% for Hillsborough, Orange, and Duval: those are new-buyer numbers, not the statewide average.
Use the higher figure when budgeting. The 0.8% is what you may drift toward after a decade under the cap.
The exemptions below are what make Florida genuinely cheap for long-term homeowners — and what make the first year a shock for everyone else.
2. The $50,000 Tax Break: Florida's Homestead Exemption
The Homestead Exemption is a big reduction in the taxable value of your primary residence.
If the home is where you actually live, you can knock up to $50,000 off its assessed value.
More importantly?
It unlocks the Save Our Homes cap. The $50,000 is nice. The cap it turns on is where the real money is.
It comes in two layers.
The first $25,000 (applies to all taxes)
The first $25,000 of exemption reduces all your property taxes — including school district taxes. Every homesteaded property gets this.
The second $25,000 (non-school only, inflation-adjusted)
A second exemption of up to $25,000 applies to the assessed value between $50,000 and $75,000 — but it does not apply to school district taxes.
Here's the kicker:
Thanks to a 2024 constitutional amendment, this second exemption is now adjusted for inflation each year. For the 2025 tax year it sits at $25,722 (a 2.9% CPI adjustment, per the Florida Department of Revenue). (Confirm the current figure with your county property appraiser.)
| Layer | Amount | Applies to assessed value… | Reduces school taxes? |
|---|---|---|---|
| First exemption | $25,000 | $0 – $25,000 | Yes |
| Second exemption | Up to $25,000 (indexed — $25,722 for 2025) | $50,000 – $75,000 | No |
Note the gap: assessed value between $25,000 and $50,000 gets no exemption at all. That's not a typo — it's how the two layers are written.
How to file (and the March 1 deadline)
The exemption isn't automatic. You have to apply.
⚠️ March 1 or Wait a Year
File with your county property appraiser by March 1 of the year you want it to take effect. Miss it, and you wait a full year — losing both the exemption and a year of Save Our Homes cap protection.
Most counties let you file online. You'll generally need proof the home is your permanent residence: a Florida driver's license, voter registration, and similar.
3. Save Our Homes: The Ultimate Tax Shield
This is where the real long-term money is.
Once your home is homesteaded, Save Our Homes limits how much your assessed value can increase each year — to 3%, or the change in inflation (CPI), whichever is lower.
Here's why this matters:
Florida home values can rise 10%+ in a hot year. But your taxable value can only rise 3% at most.
Over time, a gap opens between your home's market value and its capped assessed value. You don't pay tax on that gap.
What the gap looks like after a decade
Two identical houses sit side by side, both worth $500,000 today.
House A was bought in 2015 for $250,000 and homesteaded immediately. Under the 3% cap, its assessed value has crawled up to roughly $335,000 — so its owner pays tax on $335,000 minus exemptions, not $500,000.
House B sells to you today for $500,000. Your assessed value: $500,000.
Same house. Same street. Same market value. Your neighbor's bill is calculated on roughly two-thirds of yours. That's not unfair — it's just the cap doing its job, and one day it'll do the same for you. But it's exactly why their tax line tells you nothing about your own. (Illustrative figures — actual assessed values depend on each year's CPI and your county's millage.)
Long-time Florida homeowners often pay tax on a fraction of what their home is actually worth. The cap starts the year after your Homestead Exemption is granted — so filing promptly also starts your cap clock sooner.
4. The "Reset" Trap: Why Your Tax Bill Jumps After Closing
Look: this is the single biggest mistake first-time buyers make.
When you're shopping, the listing often shows the current owner's property tax bill. If they've owned for years, Save Our Homes has kept their assessed value low — so that number looks great.
But it's not your number.
When the home sells, the Save Our Homes cap resets. The property gets reassessed at roughly market value — which is what you just paid.
The result?
Your first-year tax bill is calculated on your purchase price, not the seller's decade-old capped value. That can mean a bill hundreds or even thousands of dollars a year higher than the listing showed.
📖 The assessment reset, in one line
The Save Our Homes benefit belongs to the owner, not the house. It does not convey with the sale. On January 1 following your purchase, the county reassesses at market value and your clock starts at zero.
So always estimate your taxes off your purchase price, not the seller's bill. A safe starting point is your county's effective rate (often ~1%–2%) times what you plan to pay.
Our Florida Mortgage Calculator lets you enter your own tax figure, so your payment is realistic from day one.
5. Portability: How to Move Your Tax Savings
Already own a Florida home and moving to a new one?
You don't have to lose all those years of Save Our Homes savings.
Portability lets you transfer your accumulated benefit — the gap between your old home's market and assessed value — to your new Florida homestead, up to $500,000.
📦 Portability rules
Up to $500,000 transferable- Timing: establish the new homestead within three tax years of giving up the old one
- Paperwork: file Form DR-501T alongside your new Homestead Exemption application
- Direction: works whether you're buying up or down in value, though the calculation differs
For repeat buyers, portability can be worth thousands a year — don't leave it on the table. (Confirm the current cap and window with the Florida Department of Revenue or your county appraiser.)
6. What If It's an Investment Property?
Buying a second home, a rental, or an investment property?
Those don't get the Homestead Exemption or the 3% Save Our Homes cap.
But they do get a weaker protection: a 10% annual cap on assessed-value increases — which also doesn't apply to school district taxes.
| Primary residence (homesteaded) | Second home / rental / investment | |
|---|---|---|
| Homestead Exemption | Up to $50,000 | None |
| Assessment cap | 3% or CPI, whichever is lower | 10% |
| Cap covers school taxes? | Yes | No |
| Portability | Yes, up to $500,000 | No |
It's better than nothing — but it's why investment properties carry a heavier tax load than owner-occupied homes.
7. How to Calculate Your Exact Tax Bill in 6 Steps
Here's how to get a realistic number before you buy:
- Start with your purchase price — not the seller's assessed value. This is your likely new assessed value.
- Subtract the Homestead Exemption if it'll be your primary residence — up to $50,000 (remember the second $25K doesn't reduce school taxes).
- Multiply by your local millage rate — or use the county's effective rate as a shortcut (often ~1%–2%). Your county property appraiser publishes the exact millage.
- Add any special district or CDD assessments — common in newer communities, billed on the same statement.
- Divide by 12 to get the monthly amount that lands in your escrow.
- Plug that figure into your payment using the Florida Mortgage Calculator, so taxes are baked into the payment you actually see.
Worked example: a $350,000 primary residence
You buy at $350,000 in a county with a ~1.5% effective rate, and it's your primary residence.
Roughly: ($350,000 − $50,000 homestead) × 1.5% ≈ $4,500/year, or about $375/month into escrow.
One caveat: the school portion of your millage is calculated against a smaller exemption (the second $25K doesn't reduce school taxes), so your real bill will run a bit higher than this shortcut suggests. Always confirm with your county's official estimator. (Estimates vary by county and millage.)
8. The 2026 Ballot Amendment (Will Your Taxes Drop?)
⚠️ Not Law — Pending a November 2026 Vote
Everything in this section describes a proposed constitutional amendment that has not passed. It requires 60% voter approval on November 3, 2026 to take effect.
Do not budget around it, and do not let it change a buying decision today. Treat it as a possibility, not a benefit.
Florida voters will decide a major property tax measure on the November 3, 2026 ballot — a constitutional amendment known as HJR 1, "Save Our Homes from Excessive Property Taxes."
(Some outlets refer to it by an assigned ballot number. Confirm the final ballot designation closer to the election.)
If it passes, here's what it would do:
| Change | Detail | Effective |
|---|---|---|
| Much larger non-school homestead exemption | $150,000, rising to $250,000, then indexed to inflation. The school-tax exemption stays at $25,000 | 2027 → 2028 |
| New residents phase in | People establishing Florida residency after Dec 31, 2026 get a $50,000 exemption for their first five years | 2027 |
| Tighter investment cap | The 10% cap on non-homestead property drops to 5% | 2027 |
| Save Our Homes & portability | No change | — |
It still needs 60% voter approval, and details can shift before the vote. Verify before relying on any of it.
9. 5 Costly Property Tax Mistakes
🚫 The Five That Cost the Most
- Budgeting off the seller's tax bill. The number one mistake. Yours resets to your purchase price
- Assuming Homestead is automatic. You must file by March 1
- Thinking the cap locks your final bill. Save Our Homes caps your assessed value growth, not the millage rate — a tax-rate hike can still raise your bill
- Forgetting portability. Repeat buyers who don't file for it leave real money behind
- Ignoring CDD and special-district fees. They ride on the same bill and aren't covered by the Homestead Exemption
10. Frequently Asked Questions
What is the Florida Homestead Exemption?
It's a reduction of up to $50,000 in the taxable value of your primary residence. The first $25,000 applies to all property taxes; a second $25,000 applies to value between $50,000 and $75,000 but not to school taxes. It also unlocks the Save Our Homes cap. You must file with your county appraiser by March 1.
How does Save Our Homes work?
Once your home is homesteaded, Save Our Homes caps annual increases in your assessed (taxable) value at 3% or the rate of inflation, whichever is lower. Over time this keeps your taxable value well below market value, saving long-term owners thousands. The cap begins the year after your Homestead Exemption is granted.
Why did my Florida property tax go up so much after I bought?
Because the assessed value resets to your purchase price when you buy. The Save Our Homes benefit belongs to the owner, not the house — it doesn't convey with the sale. The seller's low, capped bill doesn't transfer to you, so your first-year taxes are based on what you paid.
What is property tax portability in Florida?
Portability lets you transfer up to $500,000 of your accumulated Save Our Homes benefit from your old Florida homestead to a new one, as long as you establish the new homestead within three tax years. File Form DR-501T with your new Homestead application.
What is Florida's property tax rate?
The statewide effective rate is roughly 0.8% of home value, near the national average — but that average is dominated by long-time owners whose assessments are capped. As a new buyer you reset to market value, so budget closer to 1%–2% of your purchase price depending on county millage. Check your county property appraiser for the exact rate.
Is Florida getting rid of property taxes in 2026?
No. A constitutional amendment on the November 3, 2026 ballot (HJR 1) would sharply raise homestead exemptions on non-school taxes — $150,000 in 2027, rising to $250,000 in 2028 — but it does not eliminate property taxes, and it needs 60% voter approval to take effect. It is not law, so don't budget around it.
When is the deadline to file for Homestead Exemption?
March 1 of the year you want the exemption to apply. Filing is done through your county property appraiser, usually online. Missing it costs you a full year of both the exemption and Save Our Homes cap protection.
Do investment properties get the Save Our Homes cap?
No. Second homes, rentals, and investment properties get no Homestead Exemption and no 3% cap. They do get a weaker 10% annual cap on assessed-value increases, which doesn't apply to school district taxes, and they can't use portability.
