The Truth About Property Taxes

Why does my Florida property tax bill go up after I buy a house?

Florida resets a home's assessed value — the number your tax bill is built on — to full market value on January 1 of the year after it sells. The tax figure you saw on the listing belonged to the seller, who may have held it down for years. On a $640,000 Destin home, plan on roughly $6,400 a year, or about $533 a month, even if the old bill was half that. Vacation homes and rentals get no homestead exemption at all.

The listing said the taxes were $2,800 a year. Fourteen months later, the bill was $6,400.

Nothing went wrong. Nobody made a mistake. That's how Florida property tax works when a house changes hands — and it catches almost every out-of-state buyer on the Emerald Coast off guard.

If you're buying a second home in Destin, a beach cottage on 30A, or a rental in Miramar Beach, this is the single most common surprise in your first year of ownership. It's also completely predictable. Here's the math before you write an offer.

The number on the listing is the seller's number, not yours

Florida gives a big break to people who live in their home full-time. Two things drive it.

The first is the homestead exemption — up to $50,000 knocked off the assessed value of a primary residence. On a Destin home that's worth roughly $550 to $700 a year.

The second matters far more over time. It's called Save Our Homes — a cap that limits how much a homesteaded property's assessed value can rise each year to 3% or the rate of inflation, whichever is lower. A couple who bought in Crystal Beach in 2014 and lived there ever since may be paying tax on an assessed value of $280,000 while the house is worth $640,000 today.

That's the bill you saw on the listing sheet. It doesn't come with the house.

When the property sells, Florida law requires the county property appraiser to reassess it at full market value as of the January 1 following the sale. Buy in May 2026, and your first full-value bill lands for the 2027 tax year. Every dollar of the seller's accumulated savings disappears the moment the Warranty Deed is signed.

Then comes the second hit, and it's the one that gets second-home buyers. If the property isn't your primary residence, you don't get the homestead exemption or the 3% cap. Vacation homes, short-term rentals, and investment properties are treated as non-homestead property. They're capped at 10% growth a year instead of 3%, and that 10% cap doesn't cover the school district portion of your bill — that piece gets assessed at full market value every single year.

What you'll actually pay, from Destin to 30A

Tax rates on the Emerald Coast are set by a stack of taxing bodies — county, school district, and in some places a city or a charge attached to your lot for services like fire or road maintenance. Rather than hand you a pile of millage rates, here's what real bills look like as a share of what a home is worth.

A few things jump out of that table.

Destin runs the highest of the group because the city levies its own tax on top of the county and school district. Cross the county line into Walton County and the rate drops — the median Walton County bill works out to about 0.74% of value, against roughly 0.90% countywide in Okaloosa.

But the rate is only half the story. Walton County's lower rate sits under much higher prices. The median home in Inlet Beach is worth about $1.25 million and carries a median tax bill of about $8,557 a year. In Santa Rosa Beach, the median is roughly $745,000 with a bill near $4,766. A lower percentage of a much bigger number is still a big number.

These are medians drawn from actual county records, not quotes. Your specific address will land somewhere in a range, because school district lines and local service charges shift block to block. Treat the table as a budgeting starting point and verify the parcel before you go under contract.

If you're underwriting a rental, this line belongs in your model at full reset value from day one. We walk through the rest of that math in our breakdown of vacation rental returns on 30A and in Destin, and property tax is usually the single biggest fixed cost after the mortgage — bigger, in many cases, than what flood insurance runs on the same property.

Primary home or vacation home — the gap widens every year

Two buyers close on identical $640,000 homes in Destin on the same day. One moves in full-time and files for homestead. The other keeps it as a beach place and rents it out in the summer.

Year one, their bills look about the same — roughly $6,400 each, minus a few hundred dollars for the full-time owner's exemption.

Now let five years pass with home values rising about 6% a year.

• The full-time owner's assessed value can only climb 3% a year. After four years of growth it sits near $720,000.
• The second-home owner's assessed value tracks the market, since 6% growth falls under the 10% ceiling. After the same four years it sits near $808,000.

That's an $88,000 spread in taxable value, worth about $900 a year. Add back the exemption the second-home owner never got, and the gap runs closer to $1,500 a year by year five — and it keeps widening as long as prices rise.

None of that makes a second home a bad buy. It does mean the carrying cost you model in year one understates what you'll pay in year six. Build in the drift.

One more piece worth knowing if you're moving to Florida from another Florida home: portability. If you're selling a homesteaded Florida property and buying a new primary residence here, you can carry up to $500,000 of your accumulated Save Our Homes savings with you. You file Form DR-501T, and you have three tax years from the year you left the old homestead to claim it. Plenty of people relocating from Central or South Florida leave that on the table because nobody told them.

What the November 2026 ballot measure would change

There's a property tax amendment on the Florida ballot on November 3, 2026 — Amendment 3, from House Joint Resolution 1-F. It passed the Legislature in a June special session and needs 60% voter approval to take effect on January 1, 2027.

Two changes matter here.

1. A much larger homestead exemption. For non-school taxes, the exemption would rise from $50,000 to $150,000 in 2027, then to $250,000 in 2028.
2. A tighter cap on everything else. The annual assessment growth limit on non-homestead property — second homes, rentals, commercial — would drop from 10% to 5%.

Here's the honest read: the headline tax cut is aimed at full-time Florida residents. If you're buying a vacation home in Destin or on 30A, the bigger exemption does nothing for you. You get the tighter 5% cap, which is real but modest — on that same $640,000 home growing 6% a year, a 5% cap saves roughly $300 a year by year five compared to today's rules.

It's also not law yet. Don't underwrite a purchase on the assumption it passes.

The dates that matter, and how to check before you offer

Florida's tax calendar runs on a fixed schedule. Four dates do the work.

1. January 1 — the valuation date. Whatever the property is worth that morning sets the year's assessment. This is why a May closing shows up on the following year's bill.
2. March 1 — the deadline to file for homestead exemption if the home became your primary residence. Miss it and you wait a full year.
3. August — your TRIM notice arrives. TRIM stands for Truth in Millage, and it's a proposed tax notice, not a bill. It shows your new assessed value and an estimate of what you'll owe. Read it. You generally have about 25 days from the mailing date to petition — the deadline in both Okaloosa and Walton County lands around September 15.
4. November 1 — the actual bill is issued. Pay it in November and you get a 4% discount. The discount shrinks each month and disappears by March.

Before you write an offer, do two things.

Pull the parcel on the county property appraiser's site — Okaloosa County at okaloosapa.com, Walton County at waltonpa.com. Both post the current assessed value, the exemptions the seller holds, and a tax estimator that lets you plug in your purchase price. That estimator is the number to put in your budget, not the one on the listing.

Then ask your lender to escrow at the reset amount. Escrow is the account your lender collects into each month to pay the tax bill for you. Many lenders set up that first-year escrow using the seller's old tax figure, which produces a shortage notice and a payment jump about eighteen months in. Flag it up front and you avoid the whole thing.

Property tax is one of several carrying costs that look different on the Emerald Coast than they do where you're coming from. It's worth reading alongside what buyers actually pay at closing so the full picture is in front of you before you commit.

Frequently Asked Questions

Does the seller's homestead exemption transfer to me when I buy?

No. The exemption and the Save Our Homes cap belong to the person, not the property. Both end when the home sells, and the county reassesses at full market value on the January 1 following the sale. If you make the home your primary residence, you file for your own exemption by March 1.

Can I get a homestead exemption on a vacation home in Destin or on 30A?

No. Florida's homestead exemption applies only to a permanent primary residence. Second homes, short-term rentals, and investment properties are non-homestead and receive no exemption. They do get a 10% annual cap on assessed value growth, though that cap doesn't apply to the school district portion of the bill.

How much are property taxes on a $1 million home on 30A?

In Santa Rosa Beach, where bills run about 0.73% of value, budget roughly $7,300 a year, or about $608 a month. In Inlet Beach, at about 0.76%, it's closer to $7,600 a year. Verify the specific parcel with the Walton County Property Appraiser, since local service charges vary by community.

When exactly does the higher bill show up?

The January 1 after your closing sets the new assessed value, your TRIM notice arrives that August, and the bill is issued November 1. So a buyer who closes in May 2026 sees the reset value on the August 2027 notice and pays it in November 2027 — roughly eighteen months after closing.

Is it worth appealing my assessment?

Sometimes, particularly if you paid below the appraiser's market value or the property has condition issues the county hasn't accounted for. You petition the Value Adjustment Board, generally within about 25 days of your TRIM notice — around September 15 in Okaloosa and Walton County. Bring comparable sales or an independent appraisal.

The takeaway

The property tax figure on a Destin or 30A listing is a historical artifact of the seller's ownership. Yours resets to full market value, and if the home isn't your primary residence, it resets without the exemption and without the 3% cap. Run your budget on the county's estimator at your purchase price, and the surprise never happens.
