Welcome to City of Troy, Michigan

The total tax rate consists of millage rates for our public schools, the City of Troy, and Oakland County. School millage rates vary among school districts. Each school district has a Principal Residence Exemption rate for the residence owned and occupied by the taxpayer, and a non-Principal Residence Exemption rate for property not occupied as a principal residence by the taxpayer.

The millage rate times the taxable value (per thousand) is your tax obligation.

Example:
Taxable value ($150,550) x Millage rate (30.6705) - Divide by 1000 - Equals Estimated yearly tax

$150,550 TV x 30.6705 = $4,617,443.78 / 1000 = $4,617.44

Below are tables with the total millage rates for each school district within the City.

Supplemental

This levy is used in school districts whose per pupil funding would not equal last year if that district only received its share of the State Education Tax and its operating levy for funding. This levy has sometimes been referred to as "hold harmless millage".

School Operating

As a result of Proposal A, this millage now applies only to Non-Principal Residence properties. The collection of this tax is remitted directly to the school district. This levy is subject to voter approval as current authorized millage expires.

State Education

This is the tax levy which was authorized by the passage of Proposal A. These funds go to the State of Michigan and are distributed to the school districts. State law required that beginning July of 2003, the entire State Education Tax (SET) will be collected in the summer levy.

Intermediate Schools

This is the levy of the Intermediate School District. Proposal A did not affect this levy and it appears only on the summer tax bill.

Community College

This levy goes to Oakland Community College and appears only on the summer tax bill.

Oakland County

Public Act 357 of 2004 amends the General Property Tax Act so that 100% of the county's fixed allocation millage shall be collected in July of each year.
