 What is a millage?

The general property tax funds school districts, townships, villages, cities and counties of the state. The tax rate, or millage, is the number of dollars the property owner must pay for each $1,000 of taxable value.  This rate varies by local unit, but certain statewide constitutional and statutory restrictions exist. 

How is my property tax calculated?

Your property tax is determined by multiplying your total local millage rate by your taxable value.  The Michigan Department of Treasury now has a property tax estimator on its website ( 

Why aren't everyone's summer tax rates the same?

Clinton Township residents are served by five local school districts, thus summer millage rates are not the same throughout the Township.  You can review the various millage rates levied by clicking on the "Tax Rates" link at the top of this page.


On March 15, 1994, the voters of Michigan passed a state constitutional amendment known as Proposal A.  This proposal created a new term called Taxable Value (TV), or the figure against which millage would be multiplied to determine property taxes.  

Proposal A requires that:

  • Assessments (State Equalized Value or SEV) be calculated yearly at 50% of the true cash value, as determined by 1-2 year studies of market sales that occur during a time frame that is outlined by the State Tax Commission. (2009 assessments were based on a single year study of sales occurring between October 1, 2007 thru September 30, 2008) 
  • Taxable Value (TV) for parcels be determined using a methodology mandated by the State legislature, and which can not be changed by any local community.  The calculation formula takes the previous year's taxable value, minus any physical losses to the property, plus any physical additions to the property, multiplied by 5% or the rate of inflation - whichever is less.  Rate of inflation is determined by the state (4.4% for 2009).

Proposal A "caps" the growth in TV in those years when market values (Assessed Values) are increasing faster than inflation. Over the course of many years, Proposal A allows many taxpayers to pay property taxes on significantly less than the market value of their property.  

Proposal A's Relationship to Housing Market Downturns

As long as the TV of a property remains less than the SEV, TV will increase under Proposal A's formula.   If there is a significant gap between the SEV and TV figures for owners, it would take several years of depressed market conditions for the TV to catch up to SEV.  Thus,  a tax increase could occur for many homeowners even in a market downturn. 

Taxable Value Reset Upon Transfer of Property

When property is transferred, the TV is reset or "uncapped" and returned to being the full (SEV) for the following year.  This most often results in a new property owner paying higher taxes than the previous owner, who may have been benefitting from many years of capping.  Potential buyers should always use SEV when estimating a property's tax liability.





Each tax cycle begins July 1 and concludes on the last day in February.  *Exception: If the last day of February falls on a Saturday or Sunday, the last day for collection moves to the next business day.

Summer taxes are liened July 1 and payable through September 14 without interest. From September 15th to September 30th a 1% late fee will be assessed.  An additional 1% will be assessed the first of each month thereafter through the end of February.

Winter taxes are liened December 1 and payable through the end of the tax cycle without interest.

As of March 1, unpaid taxes are considered  delinquent (with the *Exception noted above)  and must be paid to the Macomb County Treasurer's Office.  The County Treasurer's Office is located in the Macomb County Administration Building at One South Main in Mount ClemensClinton Township DOES NOT have records of payments made to the Macomb County Treasurer for delinquent taxes. You must contact the Macomb County Treasurer (586-469-5190) to determine pay off amounts for delinquent taxes or to verify if delinquent taxes have been paid.   You can also obtain delinquent property tax information on the County website:


Tax bills should be received the first week in July and the first week of December. If you do not receive a tax bill at these times, please call the Treasurer’s Office at (586) 286-9313.  Failure to receive a tax bill does not waive responsibility for making payment by the due date.  

Important Information for New Buyers:  Tax bills are prepared in June and November.  The transfer of property during these periods can result in tax bills reflecting the previous owner's name rather than the new responsible party.  In addition, the U.S. Post Office directs mail based upon the addressee information on record.  Consequently a tax bill could be forwarded to the former owner's new address.  New homeowners should call or stop in at the Treasurer's Office to make certain they receive their tax bill.
