Florida Property Tax Calculator
The tax figure printed on a listing belongs to the seller. Yours is calculated on what you paid.
What This Calculator Does
Give it the purchase price, your homestead status, and the millage attached to the address, and it models the assessment reset that follows every sale. Florida re-values property at market on the January 1 after a transfer, which is why your budget should be built on your price rather than on the seller's capped assessed value.
Who Is This For
Buyers who read the current tax line on a listing and assumed it transfers, Florida homeowners moving within the state who want to see what portability keeps, and out-of-state purchasers pricing the genuine carrying cost of a Miami property.
How It Works
Enter the purchase price, indicate whether the property will be your homestead, and add the millage rate for the taxing authorities covering that address. The output shows the projected assessed value after reset, the exemptions applied, and the estimated annual tax.
Frequently Asked Questions
Why is the seller paying less than I will?
Save Our Homes capped their assessed value throughout their homestead ownership, while yours resets to market value on the January 1 after the sale. On a long-held property the distance between assessed and market value can be enormous, and it closes the instant title changes hands. Read the listing's tax figure as history rather than forecast.
What is the homestead exemption worth?
The standard homestead exemption comes to $51,411 for 2026. The first tier reaches all taxing authorities; the second is indexed to CPI annually and does not apply to school district levies, which is why your school taxes fall by less than the headline figure implies.
How does the Save Our Homes cap work?
With homestead in place, the yearly rise in assessed value is held to 3% or the change in the Consumer Price Index, whichever proves lower. It shields you going forward from your own reset assessment — and it stays behind when the house sells.
Can my old assessment come with me?
In part. Portability moves accumulated Save Our Homes benefit — the gap between market and assessed value — up to $500,000 onto a new Florida homestead. It has to be filed for, and the deadline is tied to the homestead application, so raise it before your first January in the new home.
And if it is not my homestead?
Second homes, rentals, and investment property receive no homestead exemption and no Save Our Homes cap. A 10% annual cap on assessed value increases applies instead for non-school levies, which is far weaker protection and still allows sharp jumps.
Is the exemption about to increase?
A constitutional amendment raising the homestead exemption sits on the November 3, 2026 ballot. It is not law today, and this calculator applies the rules currently in force. Never build a purchase budget on a ballot measure that has not passed.
