Marion County property tax and homestead estimator
The county publishes a millage rate for each of its sixteen taxing districts. This applies the one you pick, and the homestead exemption if it is your primary residence.
Bottom line
- Marion County has sixteen taxing districts and the millage is not the same in each — the spread across them is wide enough to matter on the same house.
- Florida's homestead exemption takes $50,000 off the taxable value of a primary residence, in two bands that do not work the same way.
- This covers ad valorem taxes only. Non-ad valorem assessments are billed separately, vary by parcel, and are not estimated here — so a real bill runs higher than this figure.
Estimated ad valorem tax

This homesteaded figure errs low. The $50,000 to $75,000 exemption band does not apply to school district millage, and the county publishes these rates as totals with school millage already inside them. Rather than invent the split, this applies the whole exemption against the whole rate. Your actual bill will be somewhat higher.
How Florida property tax actually works
Your bill is taxable value multiplied by the millage rate, divided by a thousand. A mill is one dollar per thousand dollars of taxable value, so a rate of 15.5871 mills on a taxable value of $250,000 is $3,897 a year.
The part people arriving from other states find unfamiliar is that the millage is not one number for the county. It is the sum of every authority that taxes your particular parcel — the county, the school board, the water management district, the city if you are inside one, and any special district. That is why there are sixteen entries in the dropdown above rather than one, and why two houses fifteen minutes apart can carry noticeably different bills.
The homestead exemption
If the property is your permanent residence as of January 1, you can file for homestead by March 1 with the Property Appraiser. It does two things, and the second is worth more than the first over time.
The exemption itself takes up to $50,000 off your taxable value, in two bands: the first $25,000 comes off for every taxing authority, and the band between $50,000 and $75,000 of assessed value comes off for all of them except the school district.
Save Our Homes is the other half. From the year after your exemption is granted, the assessed value of your homesteaded property cannot rise more than 3% a year, or the change in the Consumer Price Index, whichever is lower — regardless of what the market does. Over ten years in a rising market that cap is usually a much larger number than the exemption, and it is the main reason a neighbour who has been there fifteen years pays a fraction of what a new buyer pays on the identical house.
Filing is free and you do it once. The Property Appraiser's office is the only place that does it.
What this does not include
Non-ad valorem assessments. These are charges that are not based on the value of the property — fire services, solid waste, stormwater, street lighting, and assessments levied by special districts. They appear on the same annual bill as your ad valorem taxes and they vary from parcel to parcel, sometimes considerably.
This estimator does not include them and does not estimate them, which is the same basis the Property Appraiser's own estimator uses and says so on. When you are looking at a specific property, ask for the full prior-year tax bill rather than just the tax figure on a listing, because the listing figure is often the ad valorem half only.
What this calculates, and on what assumptions
You give it a value and a taxing district; it applies the Property Appraiser's published millage for that district and, if you tell it the home is your permanent residence, the Florida homestead exemption in the two bands the statute actually creates — the first band exempt from every authority, the second exempt from all of them except the school district. That split is why an estimator that subtracts one flat figure gets the answer wrong.
Two assumptions to hold on to. The millage in this site's data file is the proposed rate for the stated tax year, which is what is published for most of the year and can change when the roll is certified. And the figure you type is treated as the taxable value — a Property Appraiser assesses a specific parcel, and Save Our Homes caps how fast an existing homestead's assessed value can rise, so a long-held home's assessed value can sit well below what it would sell for.

Common questions
Is this what my tax bill will say?
No, and it will read lower than your bill. Two reasons. It covers ad valorem taxes only, and a real bill also carries non-ad valorem assessments — fire, solid waste, stormwater and similar — which are billed separately and vary by parcel. And it applies the full homestead exemption against the full millage, which understates a homesteaded bill slightly, for the reason in the next answer.
Why does it say the homestead figure is a little low?
Florida's homestead exemption comes in two bands. The first $25,000 is exempt from every taxing authority. The band from $50,000 to $75,000 is exempt from every authority except school districts. Calculating that properly needs the school portion separated out of the millage, and the Property Appraiser publishes these sixteen rates as totals with school millage already inside. Rather than invent a split, this estimator applies the full exemption against the full rate and tells you it is erring low.
What is Save Our Homes?
A cap on how fast the assessed value of a homesteaded property can rise — 3% a year or the change in the Consumer Price Index, whichever is lower. It starts the year after the exemption is granted, so it does not affect a first-year estimate, but over a decade it is the single largest thing separating a long-time owner's bill from a new buyer's on identical houses.
These are proposed rates. What does that mean?
Taxing authorities set proposed millage during the summer Truth in Millage process, and the rates can change before the tax roll is certified in the autumn. The Property Appraiser labels them proposed on their own estimator and this page carries the same label rather than presenting them as final.
