When is the homestead exemption deadline in Florida?

March 1 of the tax year you are claiming. You must have owned the property and made it your permanent residence as of January 1 of that year. Filing after March 1 generally means waiting for the next year, so a house bought in February is often a house whose exemption starts the following January.

How much does the homestead exemption save?

It removes up to $50,000 from taxable value, in two bands. The first $25,000 applies to every taxing authority. The second $25,000 — the band between $50,000 and $75,000 of assessed value — applies to every authority except school districts. Because school millage is a large share of a Florida bill, the cash saving is meaningfully less than $50,000 multiplied by your total millage rate.

What is Save Our Homes?

A constitutional cap on how fast the assessed value of a homesteaded property can rise: 3 percent a year or the change in the Consumer Price Index, whichever is lower. It applies from the year after the exemption is granted. Over a long tenure it separates assessed value from market value substantially, which is why a long-time owner's tax bill is not a guide to what a new buyer will pay.

Can I transfer my homestead from another Florida county?

The exemption itself is filed fresh on the new property, but the accumulated Save Our Homes benefit can often be carried with you. That is portability, and it has its own application, its own deadline and its own arithmetic depending on whether you are moving up or down in value. Ask the Property Appraiser before you file rather than after.

Do I lose the exemption if I rent the house out?

You can. Homestead requires the property to be your permanent residence, and renting it out — particularly for extended periods — can disqualify it. Improperly claimed exemptions are recoverable by the Property Appraiser with penalties and interest, so if your circumstances change, tell them rather than waiting to be found.

Florida homestead exemption: how to file and what it saves

Two exemption bands that behave differently, an assessment cap worth more than the exemption itself after a few years, and a deadline that is not on your closing paperwork.

Homestead is the single most valuable piece of paperwork a new Florida homeowner files, it takes about fifteen minutes, and a surprising number of people miss it in their first year because nothing in the closing process reminds them.

What it is

Two separate things, usually described as one:

The exemption — up to $50,000 removed from the taxable value of your permanent residence, which reduces this year's bill.
Save Our Homes — a cap on how fast your assessed value can rise in future years, which reduces every year after this one, compounding.

The second is worth more than the first for anyone who stays put. People file for the first and receive the second without noticing.

Both are in the Florida Constitution rather than in ordinary statute, which is why they have survived every budget cycle since they were adopted.

The exemption, and the band that is not what it looks like

The headline is "$50,000 off". The mechanics are two bands that behave differently:

Band of assessed value	Exemption	Applies to
First $25,000	$25,000	All taxing authorities
$25,000 to $50,000	none	—
$50,000 to $75,000	$25,000	All authorities except school districts

That middle row is real: the second exemption only starts once assessed value passes $50,000, which is why a very low-valued property gets $25,000 rather than $50,000.

The last row is the one that costs people money in their own arithmetic. School millage is a large component of a Florida property tax bill, and the second $25,000 does not touch it. So:

Wrong: $50,000 × your total millage = your saving.
Right: $50,000 × your non-school millage, plus $25,000 × your school millage.

The Marion County Property Appraiser publishes district rates as totals, with school millage already inside them, which means a calculator working from published data cannot split them. This site's property tax estimator therefore applies the full $50,000 against the full rate and says on the page that the real bill runs a little higher. An estimate that is transparently low is better than one that is silently wrong in your favour.

Save Our Homes, which is the part that compounds

Once the exemption is granted, the assessed value of your homestead can rise by no more than 3 percent a year, or the change in the Consumer Price Index, whichever is lower. Market value does whatever the market does. Assessed value walks up slowly behind it.

Two consequences, and they matter in opposite directions:

For you, staying: every year the gap widens, and the gap is money. After a decade in a rising market the difference between what your house would sell for and what you are taxed on can be very large. This is the real reason long-time Florida owners are reluctant to move house even when the house no longer suits them.

For you, buying: the seller's tax bill is their capped number, not yours. When the property sells, the assessment resets toward market value for the new owner. The tax figure on a listing is frequently not a number any buyer will ever pay. It is the single most expensive misreading in a Florida house hunt, and it catches people who are otherwise doing their homework properly.

The cap starts in the year after the exemption is granted, so your first full year is uncapped.

Filing: the actual steps

Own it and live in it on January 1 of the year you are claiming. Not "under contract on January 1" — owned, and your permanent residence.
File with the Marion County Property Appraiser by March 1. Their office takes applications and publishes the current method; many Florida counties accept online filing.
Bring proof of Florida residency. In practice: Florida driver's licence, Florida vehicle registration, Marion County voter registration, and the recorded deed. This is why the licence and registration steps on the first-30-days checklist are worth doing in your first month rather than your first year — they are the evidence for this.
File once. The exemption renews automatically as long as you remain eligible and the county sends a renewal notice each year. Read it rather than binning it.

If you closed in, say, October, you do not have to wait until you have lived here a year. You need to own and occupy on January 1 and file by March 1. If you closed in June, your exemption starts the following January, and your first tax bill is the unexempted one — a genuinely unpleasant surprise if nobody warned you, which is most of the reason this article exists.

Portability, if you are moving within Florida

If you had a homestead somewhere else in Florida, you may be able to transfer up to $500,000 of accumulated Save Our Homes benefit to the new property. That is portability, it is a separate application from the exemption itself, and the amount depends on whether the new home's just value is higher or lower than the old one's.

The arithmetic is not intuitive and the Property Appraiser's office does it every day. Ask them before you file, not after — and note that portability has its own timing rules tied to when you gave up the previous homestead.

Other exemptions worth asking about

Homestead is the general one. Florida also provides additional exemptions, each with its own eligibility and paperwork, for categories including seniors meeting an income limit, widows and widowers, people with disabilities, and veterans with service-connected disabilities. Some are county-adopted rather than statewide.

The Property Appraiser's office is the place to ask which you qualify for, and it is worth asking once rather than assuming. Several of these are materially larger than the general exemption for the people who qualify, and none of them is applied to your account by somebody noticing on your behalf.
