Plenty of buyers come to South Florida expecting to pay roughly what the current owner pays in property tax — then get a shock when the first bill lands far higher. The reason is Florida's tax system, which rewards permanent residents with a homestead exemption and a 3% assessment cap, and treats second homes very differently. Whether you're buying a snowbird retreat or relocating full-time, understanding homestead, Save Our Homes, and portability before you sign can save you from a nasty surprise — and real money.
- A Florida primary residence can get up to a $50,000 homestead exemption plus the Save Our Homes 3% assessment cap; a second home does not.
- Property is reassessed to market value when it sells, so your bill is based on what you paid — not the prior owner's frozen, capped assessment.
- A non-homestead second home has a 10% annual cap (not 3%), which excludes school taxes and resets on sale — far weaker protection.
- Relocating full-time? Portability can move up to $500,000 of your accumulated Save Our Homes savings to a new Florida homestead.
Why Your Tax Bill Won't Match the Seller's
The single biggest surprise for Florida buyers is this: the property tax the seller pays tells you almost nothing about what you will pay. When a home changes hands, the county property appraiser reassesses it to market value — effectively, to your purchase price — on the next tax roll. A longtime owner may have been taxed on an assessed value frozen years below today's market. That protection does not transfer to you.
So a seller paying $4,000 a year on a home you buy for $650,000 is not a preview of your bill. Your taxable value resets, and if the home isn't your permanent residence, you also lose the exemptions and caps that kept the old bill low. Always budget from the reassessed value, not the current owner's line on the MLS.
What the Homestead Exemption Actually Does
Florida's homestead exemption is only for your permanent primary residence — the home you actually live in and declare as your legal domicile. It can reduce your taxable value by up to $50,000. The first $25,000 applies to all taxing authorities. A second $25,000 applies to non-school taxes on assessed value between $50,000 and $75,000.
To claim it, you have to apply with your county property appraiser (Palm Beach, Martin, St. Lucie, Broward, or Miami-Dade), and the deadline is generally March 1 of the tax year. You also have to own and occupy the home as your permanent residence as of January 1. A snowbird who keeps their legal home up north and winters in Florida does not qualify on the Florida property.
Save Our Homes: The 3% Cap That Builds Over Time
Once a home is homesteaded, Florida's Save Our Homes provision caps how much its assessed value can rise each year to 3% or the change in the Consumer Price Index, whichever is lower. In hot markets, a home's real value can jump 10–15% in a year while its assessed value inches up 3% at most.
Over time, that opens a wide gap between a longtime owner's market value and their much lower capped assessed value — which is exactly why their tax bill looks so cheap. It's a powerful benefit for permanent residents who stay put for years. But it is tied to the homestead, and it resets to full market value when the home sells, which is what resets the new owner's higher bill.
Not Sure What Your Florida Tax Bill Will Be?
A Divito Real Estate agent can estimate your reassessed taxes at your purchase price and explain whether you'll qualify for homestead, the 3% cap, or portability — before you make an offer.
Second Homes Play by Different (Weaker) Rules
A second home — a snowbird condo, a vacation place, an investment property, anything that isn't your permanent residence — gets no homestead exemption and no 3% cap. Instead, non-homestead property has a 10% annual assessment cap. That's better than nothing, but three things make it much weaker:
- It's 10%, not 3% — so your assessed value can climb more than three times faster.
- It does not apply to school-district taxes, a meaningful chunk of a Florida bill.
- It resets on sale — so when you buy, the value jumps to market and the cap starts fresh from there.
This is the classic tax-bill shock: buyers see the prior owner's low, homesteaded number and assume they'll inherit it. On a second home, you inherit none of the protection and start over at full market value.
Portability: Bringing Your Savings to a New Florida Home
If you already own a Florida homestead and are moving to another Florida home — say, upsizing in Palm Beach County or moving to the Treasure Coast — portability lets you carry your accumulated Save Our Homes benefit with you. Under Florida Statute 193.155, you can transfer up to $500,000 of the difference between your old home's market and assessed value to your new homestead, shrinking the new home's taxable value.
It isn't automatic. You have to file for it with the property appraiser (typically Form DR-501T along with your new homestead application), and there are timing rules tied to when you gave up the old homestead. Portability only helps people moving between Florida homesteads — it does nothing for a brand-new second home or a first-time buyer with no prior Florida homestead to draw from.
What Snowbirds and Movers Should Check Before Buying
You can avoid the shock by doing a little math up front. Before you make an offer, work through:
- Is this your permanent home or a second home? That single answer decides whether you get homestead and the 3% cap at all.
- Budget from the reassessed value — roughly your purchase price — not the seller's current tax line. Ask your agent or the property appraiser for an estimate at your price.
- If relocating full-time, plan to establish Florida domicile: file a declaration of domicile, get a Florida driver license and voter registration, and apply for homestead by March 1. Florida has no state income tax, which is a major reason people make the move.
- If you already hold a Florida homestead, file for portability so your Save Our Homes savings follow you.
- Remember you can homestead only one home — you can't claim it in two states at once.
A local agent can pull a realistic tax estimate at your purchase price so there are no surprises after closing.
The one-sentence takeaway
The seller's low tax bill is a mirage: Florida reassesses to market value on sale, and only a permanent residence — not a second home — earns the homestead exemption and the 3% Save Our Homes cap.
The Bottom Line
Florida's tax system quietly rewards permanent residents and offers far less to second homes, so the smartest move is to know which one you're buying before you sign. Budget from the reassessed value, not the seller's frozen bill. If you're relocating full-time, claim homestead by March 1 and bring your Save Our Homes savings along with portability. Understand the math up front, and the first tax bill will confirm your plan instead of blowing it up.

Frequently Asked Questions
Almost never. Florida reassesses a home to market value when it sells, so your bill is based on your purchase price, not the seller's frozen, capped assessment. A longtime owner with homestead and the Save Our Homes cap may pay far less than you will on the same home. Always budget from the reassessed value.
No. The homestead exemption and the 3% Save Our Homes cap apply only to your permanent primary residence — the home you actually live in and declare as your legal domicile. A snowbird retreat, vacation home, or investment property gets neither. You can only homestead one home, and only if it's your permanent Florida residence.
Non-homestead property, like a second home, has its assessed value capped at 10% per year. It's weaker than the homestead's 3% cap: the rate is higher, it doesn't apply to school-district taxes, and it resets to market value when the property sells. So a new second-home buyer starts fresh at full market value.
If you own a Florida homestead and move to another Florida home, portability lets you transfer up to $500,000 of your accumulated Save Our Homes benefit to the new homestead, lowering its taxable value. You must file for it with the county property appraiser, typically alongside your new homestead application, and timing rules apply.
Own and occupy the home as your permanent residence as of January 1, then apply with your county property appraiser by the March 1 deadline. Establishing Florida domicile usually means filing a declaration of domicile, getting a Florida driver license, and registering to vote here. You cannot claim homestead in two states at once.
Estimate from the reassessed value — roughly your purchase price — not the seller's current bill. A rough starting point is your local millage rate applied to that value, minus any homestead exemption if it's your primary home. Ask your agent or the county property appraiser for an estimate at your price before you make an offer.
