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 (how all 67 compare in the 2025 data study). 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 |
A countywide average is a planning number, not your bill: the parcel's own districts set its millage (the city table below shows the spread), and non-ad-valorem assessments (fire, solid waste, CDD) come on top. On the 2025 tax roll they came to about $29.8 million here — $166 per parcel, against $597 statewide (see the 2025 non-ad valorem study).
2025 rate decisions. The county commission set its 2025 operating rate at 5.3751 mills (2024: 4.8751), above its rolled-back rate of 4.6168, so under Florida law it was a tax increase. The 2025 millage study lists all 8 county, city and district operating rates in Seminole County on the state's report, and the vote each one took.

Actual 2025 rates by city, from the Seminole County 2025 final millage rates, as filed with the Florida Department of Revenue.
| Area | City millage (+ county fire where bought) | Total millage | Tax per $100,000 taxable |
|---|---|---|---|
| Sanford | 7.3250 | 18.1284 | $1,813 |
| Oviedo | 5.8610 + 0.1140 debt | 16.7784 | $1,678 |
| Altamonte Springs | 4.0000 + 2.7649 county fire | 17.5683 | $1,757 |
| Winter Springs | 2.6200 + 2.7649 county fire | 16.1883 | $1,619 |
| Casselberry | 3.9999 + 0.6126 debt + 2.7649 county fire | 18.1808 | $1,818 |
| Lake Mary | 3.5895 | 14.3929 | $1,439 |
| Longwood | 5.5000 | 16.3034 | $1,630 |
| Unincorporated Seminole | 2.7649 fire + 0.1107 road | 13.6790 | $1,368 |
Totals in this table run from 13.6790 mills (Unincorporated Seminole) to 18.1808 mills (Casselberry): on $100,000 of taxable value, location alone moves the bill by about $450 a year.
Every Seminole parcel pays the county's 5.3751 operating mills, 5.2490 for the school board and the St. Johns River Water Management District's 0.1793 — 10.8034 before any city or fire levy. Altamonte Springs, Casselberry and Winter Springs parcels pay the county's 2.7649-mill fire MSTU on top of the city rate. Unincorporated Seminole has the lowest total, and Lake Mary the lowest of the cities; Sanford and Casselberry are the highest.
Trash pickup. In Seminole County, homes outside city limits get garbage service this way: county contract or franchise hauler (Waste Pro and WM). Cities run their own service. Check the official page, or compare every county in the trash pickup study. Look up a home’s pickup day by address.
Fire and trash fees. On Seminole County's 2025 tax roll, there were no fire assessments and solid-waste assessments came to about $123 per parcel (statewide: $172). The 2025 fire and trash fee study compares all 67 counties.
Amendment 3 here. The state's Revenue Estimating Conference puts the cut to Seminole County's local governments at $230 million a year once Amendment 3 is fully in effect ($100 million in its first year), out of about $11.83 billion statewide. A homestead assessed at $300,000 would save about $2,006 a year here from 2028, at the county's average non-school rate. The Amendment 3 by county study shows what it would cut for every city and county government.
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 |
Homestead rows apply only the $25,000 exemption (§196.031(1)(a)) and the additional exemption up to $26,411 on non-school levies (§196.031(1)(b), 2026 CPI-indexed). Other programs stack on top; the buyer estimator models all eleven.
Buying in Seminole County? The listing's bill is not your bill
At sale the assessment resets to market (§193.155), so your first Seminole County bill tracks your price, not the seller's (the reset question below has the county's gap in dollars).

USDA income limits in Seminole County
USDA's guaranteed home loan caps household income by county. In Seminole County the limit is $132,100 for households of 1 to 4 and $174,400 for 5 to 8, counting everyone who will live in the home after small deductions (USDA's income worksheet, October 2026). That is above the $122,800 most Florida counties share, because the area's incomes run higher. The home also has to be in an eligible area: the USDA eligibility lookup checks an address and runs the income check. Other counties: all 67 USDA limits.

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) keeps the certified value record behind it; the property-tax lookup here finds both for any Seminole County address.
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, as in most Florida counties. It is custom, not law; the contract controls.
What is the USDA income limit in Seminole County?
For a USDA guaranteed loan in Seminole County, household income must be under $132,100 for 1 to 4 people or $174,400 for 5 to 8, counting everyone who will live in the home after small deductions. The home must also be in a USDA eligible area; the USDA eligibility lookup checks both.
What is the property tax rate in Sanford?
Sanford's 2025 total property tax rate is 18.1284 mills, per Seminole County's 2025 final millage filing — about $1,813 for every $100,000 of taxable value. It includes the city's own 7.3250 mills; Lake Mary totals 14.3929 and unincorporated Seminole 13.6790.
