The example below is for a residential property with an Actual Value of $800,000 for tax year 2025, paid in 2026, with an assumed Residential Assessment Rate of 7.05% for school districts, and 6.25% for local government. The school district’s Mill Levy is 30, and for all other local government districts that serve this property, the total Mill Levy is 65. The taxes would be calculated as follows:
School Districts Example
$800,000
X
7.05%
(or 0.0705)
=
$56,400
and then
$56,400
X
30
(or 30 Mills
or 0.03)
=
$1,692
Other Government Districts Example
$800,000
X
6.25%
(or 0.0625)
=
$50,000
and then
$50,000
X
65
(or 65 Mills
or 0.065)
=
$3,250
Property Tax Calculation Total
$1,692
+
$3,250
=
$4,942
