Seminole County property taxes
Seminole County — Sanford, Altamonte Springs, Oviedo and Orlando's northern suburbs — sits almost exactly mid-pack among Florida's 67 counties on average total millage. The Property Appraiser publishes directly linkable parcel pages and its own official tax estimator, so a second opinion with district-exact millage is one click away.
The 2025 numbers
Seminole County's average total millage on the 2025 certified roll is 15.348 mills — about $15.35 for every $1,000 of taxable value — the 35th-highest countywide average of Florida's 67 counties. It splits like this:
| Levy group | Mills | What it funds |
|---|---|---|
| School district | 5.249 | School board operating and debt levies — the portion the additional homestead exemption does not reduce |
| Non-school | 10.099 | County commission, municipal, water management, independent and special districts |
| Average total | 15.348 | Taxable-value-weighted countywide average, Florida DOR "Millage and Taxes Levied Report," 2025 roll |
This is a countywide average — a planning number, not your bill. Actual millage depends on the taxing districts covering the parcel (city, MSTU, special districts), and real bills add non-ad-valorem assessments (fire, solid waste, CDD) that no millage math captures.
What that means in dollars
Engine-computed examples at Seminole County's average millage, using the school/non-school split above:
| Scenario | Estimated annual tax |
|---|---|
| $300,000 assessed value, homestead (both exemptions) | ≈ $3,953.98 |
| $500,000 assessed value, homestead (both exemptions) | ≈ $7,023.58 |
| $300,000 assessed value, no homestead (investment or second home) | ≈ $4,604.40 |
The homestead rows apply the first $25,000 exemption (§196.031(1)(a), all levies) and the additional exemption up to $26,411 (§196.031(1)(b), non-school levies only, 2026 CPI-indexed) — nothing else. Widow/widower, disability, veteran, senior and other programs stack on top: the buyer estimator models all eleven.
Buying in Seminole County? The listing's bill is not your bill
Florida assessed values reset to market at sale (§193.155) — the seller's Save Our Homes cap dies at closing, and your first full bill is computed from what you paid, not what they paid. Non-homestead property carries its own 10 percent assessment cap (§193.1554), which also does not transfer. Run the buyer estimator with Seminole County pre-selected, and if you're moving a Florida homestead, the portability calculator computes what you can carry with you.
At closing, local custom in Seminole County puts the owner's title-insurance premium on the seller's side (custom, not law — the contract controls). The title calculator and seller net sheet both carry the county custom.

Quick answers
How much is property tax in Seminole County?
Seminole County's average total millage is about 15.35 mills — the 35th-highest of Florida's 67 counties. On a $300,000 assessed home that computes to roughly $3,954 a year with the homestead exemption, or about $4,604 without it. Seminole County — Sanford, Altamonte Springs, Oviedo and Orlando's northern suburbs — sits almost exactly mid-pack among Florida's 67 counties on average total millage. The Property Appraiser publishes directly linkable parcel pages and its own official tax estimator, so a second opinion with district-exact millage is one click away.
Where do I pay my Seminole County property tax bill?
Seminole County property tax bills are issued and collected by the county Tax Collector (seminolecounty.tax). The county Property Appraiser (www.scpafl.org) maintains the certified value record behind that bill, and the property-tax lookup tool on this site resolves a specific Seminole County address to both the record and the current bill in one search.
Will buying a home reset my property taxes in Seminole County?
Yes — Florida assessed values reset to market value at sale (Fla. Stat. §193.155), so the seller's Save Our Homes cap ends at closing and your first full Seminole County bill is computed from what you paid, not what the seller paid. The gap is visible in this county's own numbers: the same $300,000 home computes to about $4,604 without homestead protections versus $3,954 with them. Non-homestead property carries its own separate 10 percent assessment cap (Fla. Stat. §193.1554), which also does not transfer.
Who pays for title insurance in Seminole County?
In Seminole County, local custom puts the owner's title-insurance premium on the seller's side of the closing statement, matching most of Florida's 67 counties. This is a custom, not a law, so the purchase contract always controls who actually pays.
