See your real year-1 property tax in Orange County at purchase, not the seller's capped bill, and how much you would save if Governor DeSantis's proposed $250,000 homestead exemption passes. Orange County's 2025 total millage runs about 16.67 mills.
Orange County sits in Central Florida around Orlando. Its 2025 total millage is about 16.67 mills, of which roughly 6.50 mills fund schools and the rest covers county, city, and special-district services. On a homesteaded $425,000 home with the standard $50,000 exemption, that lands near $6,415 a year, about $535 a month. The figure moves with your purchase price, the city you buy in, and whether your community carries CDD or special-district millage, so treat it as a close estimate and run your own number above.
The number that trips up Orange County buyers is the seller's tax line on the listing. A long-time Orlando owner has years of Save Our Homes protection holding their assessed value below market, so their bill looks low. When you take ownership that cap resets to what you paid, and your first bill is usually higher. Pricing your carrying cost off the seller's old tax is one of the most common Florida buying mistakes.
Under the proposed exemption, the non-school portion of a $425,000 Orange County bill would fall by about $2,035 a year, leaving $4,380. School taxes of about 6.50 mills stay in place, which is why the bill does not reach zero. The plan is a proposed constitutional amendment. It needs 60% of the Legislature to reach the November 2026 ballot and then 60% of voters to pass, and new Florida residents would wait until their fifth year of residency to claim it. Price your home on today's real bill and treat the savings as upside if it arrives.
Two costs sit outside the millage math. Orange County Public Schools levies the school portion of every bill in the county. Communities such as Lake Nona and the Horizon West CDD villages can add CDD or special-district assessments, often $1,000 to $2,500 a year, billed separately from property tax. Cities like Orlando can also carry their own additional millage on top of the county rate. Layer homeowners insurance and any HOA dues on top of all of it for a true monthly carrying cost.
