How Much Do Property Taxes Go Up When You Buy a House in Florida? Save Our Homes & Reassessment Explained (2026)

When you buy a house in Florida, your property taxes can jump the year after the sale because the home gets reassessed at its new market value. The prior owner's "Save Our Homes" cap resets when the property changes hands, so a low tax bill you saw during the sale may not be what you pay. Exactly how much it goes up depends on the gap between the old assessed value and today's market value, plus your local millage rate.

How Much Do Property Taxes Go Up When You Buy a House in Florida? Save Our Homes & Reassessment Explained (2026)

Expect your property taxes to be based on the home's current market value after you buy, not the amount the previous owner paid in taxes. In Florida, long-time owners often have an assessed value that sits well below market value because annual increases were capped. That cap disappears when the home sells, so a new buyer can see a noticeably higher bill in the first full tax year of ownership.

The size of the increase is not a fixed number. It hinges on how long the seller owned the home, how much the market rose during that time, your county's tax (millage) rate, and whether you qualify for exemptions like the homestead exemption. In some cases the change is modest; in others it can be significant. Always treat the seller's current tax amount as a starting point, not a promise.

What homeowners should know

Your new tax bill is set by your county property appraiser, who reassesses the home to market value after the sale. This reset is the single biggest reason a buyer's taxes differ from the seller's. Understanding a few Florida-specific rules helps you plan a realistic budget before you close.

Florida property tax increase after buying a house?

After you buy, the county typically re-values the home to its current market value for the next tax roll, which can raise your bill compared with the previous owner's. The old owner's Save Our Homes benefit does not transfer to you (though a portion may transfer if you're moving from another Florida homestead — see below). Your first-year taxes are best estimated using market value, your local millage rate, and any exemptions you qualify for.

What drives the change:

• Reassessment at sale. The property is re-valued to market value, removing the seller's built-up savings.
• The Save Our Homes cap. This limits how much a homesteaded property's assessed value can rise each year. It benefits the current owner over time, but it resets when the property sells.
• Homestead exemption. If the home becomes your primary residence, you may apply for an exemption that reduces your taxable value. This can offset part of the increase.
• Portability. If you're selling one Florida homestead and buying another, you may be able to transfer some of your accumulated Save Our Homes benefit to the new home.
• Local millage rate. Your county, city, school district, and special districts each set rates. The total rate applied to your taxable value determines the bill.

How to get a realistic estimate:

• Ask your county property appraiser's office for an estimate based on the purchase price.
• Do not rely on the current tax bill shown in the listing — it may reflect a long-time owner's capped value.
• Factor in the homestead exemption and portability if they apply to you.
• Budget a cushion for the first full year, when the reassessment usually takes effect.

A trusted local real estate pro can walk you through your county's process and connect you with the right appraiser resources. When you're weighing a purchase, it helps to work with someone who knows the local rules and can point you to reliable estimates.
