How Orange County property taxes are actually calculated — and the exemptions that can cut your bill by thousands a year.
Orange County property taxes are calculated by multiplying your home’s taxable value (assessed value minus exemptions) by the local millage rate set by taxing authorities. The homestead exemption removes up to $50,000 of taxable value on your primary residence, and the Save Our Homes cap limits annual assessed-value increases to 3% — together they can save a homeowner thousands a year.
Three numbers drive your tax: the assessed value (set by the county property appraiser), your exemptions, and the millage rate (dollars per $1,000 of taxable value). Taxable value = assessed value − exemptions, then multiply by the combined millage. Different authorities — county, schools, city — each add to that rate.
If the home is your primary residence as of January 1, file for the homestead exemption with the Orange County Property Appraiser by March 1. It removes up to $50,000 from taxable value — real, recurring savings every year you own.
Once homesteaded, Save Our Homes caps your annual assessed-value increase at 3% (or CPI, if lower), so your bill stays predictable even when the market jumps. And with portability, you can carry up to $500,000 of accumulated savings to your next Florida home.
The biggest tax mistake I see new owners make is forgetting to file for homestead by March 1. That one form is worth more than most coupons they’ll ever clip. — Mourad Elbanna
Your bill is assessed value × the local millage rate, set by the county, schools, and special districts. If the home is your primary residence, the homestead exemption removes up to $50,000 of taxable value and locks in the Save Our Homes 3% annual cap on assessment increases. New buyers don’t inherit the prior owner’s capped value — your assessment resets at purchase, which is why a long-time neighbor can pay far less on an identical house.
Watch two dates. In August the county mails a TRIM notice (your proposed assessment and the deadline to challenge it). Bills come out in November, and paying early earns a discount — 4% in November, stepping down to face value by March. Apply for homestead by March 1 of the year after you buy, and confirm you can port a prior Florida home’s Save Our Homes benefit if you’re moving within the state. Buying soon?

Most people read the total and stop. Your bill actually has two different kinds of charges on it, and they behave very differently.
Ad valorem means “according to value.” That’s the part driven by your assessed value and the millage rates set by the county, the school board, and any other taxing authorities. It’s the part the homestead exemption and the Save Our Homes cap protect you on.
Non-ad valorem charges have nothing to do with your home’s value. These are flat assessments — things like a CDD, solid waste, stormwater, or fire assessments, depending on where you live. Your exemptions don’t reduce them, and a homestead cap doesn’t hold them down.
This is why two homes with the same assessed value can have very different bills. If you’re comparing properties, compare both sections, not the bottom line.
Every August, Florida property owners get a TRIM notice — Truth in Millage. It isn’t a bill, which is exactly why it ends up in the recycling. It’s the preview.
The TRIM shows your market value, your assessed value, the exemptions applied, and the proposed millage rates, along with what your taxes would be under those proposals. It’s your one clear look at how the appraiser valued your home before the bill is final in November.
It also starts a clock. If you disagree with the appraiser’s value, your window to petition the Value Adjustment Board runs from that notice — and it’s a short one, measured in days, with the deadline printed right on the notice. Miss it and you’re arguing next year.
Start with a phone call, not a petition. The Orange County Property Appraiser’s office will talk through how they arrived at your value, and plenty of disagreements end there — sometimes it’s a record error, like the wrong square footage or a bathroom you don’t have.
If the informal conversation doesn’t resolve it, you can file a petition with the Value Adjustment Board, which carries a small filing fee and gets you a hearing before a special magistrate. Bring evidence, not opinion: comparable sales near your assessment date, photos of condition issues, or documentation of anything the record gets wrong about the property.
One thing worth being clear about — you’re challenging the value, not the millage rate or your tax bill’s size. Rates are set by elected boards in public hearings. That’s a different conversation, and it happens at those meetings.
Multiply your taxable value (assessed value minus exemptions) by the combined millage rate set by the county, schools, and city. The result is your annual property tax.
It removes up to $50,000 from the taxable value of your primary residence, saving you money every year. You must own and occupy the home as of January 1 and file by March 1.
A Florida rule that limits annual increases in a homesteaded property’s assessed value to 3% or CPI, whichever is lower — keeping long-time owners’ tax bills predictable.
Because Save Our Homes capped their assessed value over years of ownership, while your value resets closer to market at purchase. Portability from a prior Florida homestead can help offset it.
Florida property taxes are billed in November and paid in arrears, with early-payment discounts for paying sooner. At closing, taxes are prorated between buyer and seller.
Usually yes in year one — your assessed value resets to your purchase price, so you won’t inherit the prior owner’s Save Our Homes cap. After you file homestead, the 3% annual cap protects you going forward.
The Truth in Millage notice Florida counties mail every August. It isn’t a bill — it shows your market value, assessed value, exemptions, and the proposed millage rates, plus the deadline to challenge your value.
Call the Property Appraiser’s office first, since many disputes are record errors that get fixed informally. If that doesn’t settle it, file a petition with the Value Adjustment Board by the deadline on your TRIM notice and bring comparable sales and documentation.
Because of non-ad valorem assessments — flat charges like a CDD, stormwater, or solid waste that aren’t based on value. Exemptions and the Save Our Homes cap don’t reduce them.
