Assessing OVerview

Michigan Statutes require that all Real and Personal Property, subject to taxation, shall be assessed annually.

Assessments are estimated at 50% of the property`s Market Value. However, property owners pay taxes based on the property`s Taxable Value. Taxable Value is the lesser of Assessed Value (SEV) or the prior year`s taxable value minus losses, increased by the lesser of 5% or the Inflation Rate Multiplier, plus Additions. A transfer of ownership will change the taxable value to the assessed value in the year following the transfer of ownership.

$100,000 Taxable Value
25 Millage Rate (Dollars per Thousand)
$2500 Estimated Annual Tax Bill

Personal Property

Business Personal Property generally consisting of office furniture and fixtures, machinery and equipment, computers, etc, is subject to taxation in the State of Michigan. Normal household furnishings are specifically exempted from personal property taxation.

Owners of assessable personal property are required to file a personal property statement on or before February 20th of each year. This date may vary for a certain type of personal property.

Contact the Assessor`s Office should you have questions about assessable personal property.

Principal Residence exemptions

To claim a PRE, complete the Principal Residence Affidavit Form 2368 and file it with your Township the year of the claim. A valid affidavit filed on or before June 1st allows an owner to receive a PRE on the current year Summer and Winter tax levy and subsequent tax levies so long as it remains your principal residence. A valid affidavit filed after June 1st and on or before November 1st allows an owner to receive a PRE on the current Winter tax levy and subsequent tax levies so long as it remains your principal residence. Your annual Assessment Notice will indicate whether your home is 100% homestead or PRE, or some percentage thereof.

PRE’s are exempt from some school operating millage rates. A property owner shall only be permitted one principal residence exemption. A signed affidavit is required from the property owner to be eligible. NOTE: It is the responsibility of the homeowner to file this affidavit. They do not expire unless they are rescinded. Please contact the Assessing Office should you have any questions about Principal Residence Exemptions.


The Assessed Value of your property reflects an estimate of 50% of your property value. This estimate is based on sales of similar homes within the same or similar neighborhoods. Your Assessed Value changes to reflect the change in selling prices of similar homes. Additionally, property improvements may increase your Assessed Value.

Taxable Value is the amount on which a property owner pays property taxes. Taxable Value is the lesser of Assessed Value (SEV) or the prior year`s taxable value minus losses, increased by the lesser of 5% or the Inflation Rate Multiplier, plus Additions. A transfer of ownership will change the Taxable Value to the assessed value in the year succeeding the transfer of ownership.

Losses are the removal of property, such as removal of a garage. An Addition includes finishing a basement, building a deck, and other improvements.

Over the years, the majority of property values in Monitor Township have increased in value greater than the IRM.  However, many neighborhoods are now experiencing a decline in the market value. The constitutional amendment know as Proposal A requires that the Taxable Value increase by the IRM, however it cannot exceed the Assessed Value.

Some property owners have a significant difference in the amount of their Assessed Values and Taxable Values. Assessed Value represents 50% of the estimated property value. Taxable Value is a mathematical formula which is based on the preceding year`s Taxable Value increased by the Inflation Rate Multiplier (IRM).  The IRM is determined by the entire State and applied by each municipality. Taxable Value may also increase for physical additions and decrease for physical losses.

The year after you purchase your home or lot, the Taxable Value is uncapped` and becomes the same amount as the Assessed Value for that year only. Each year thereafter, the Taxable Value is adjusted by the IRM in the same manner as described above.

Proposal A mandates that the Taxable Value is adjusted each year by the IRM. The assessed Value is adjusted each year based on sales studies. Sales studies are based primarily on actual sales of similar homes in similar areas. The sales analysis may indicate that the market value should increase, decrease or stay the same.

If the Assessed Value of the home is determined to be less than the Taxable Value which has been adjusted by the I RM, the Assessed Value (the lower value) becomes the Taxable Value. Taxable value is the amount on which property taxes are calculated.

Each property is valued annually. Property owners are notified annually of their revised assessment. Review the Assessment notice carefully. If you dispute the Assessed Value, the Assessor`s Office recommends that you discuss your Assessed Value and the calculation Taxable Value with our office. Also, visit the Assessor`s Office to inspect your property record for accuracy.  The property owner may appeal his/her Assessment to the March Board of Review. Taxable Value may change as a result of an Assessment revision, however, may not be appealed independently of the Assessment.


The Assessment Notice lists the date that the March Board of Review is in session.  The March Board of Review conducts informal hearings on the current year`s Assessment. Valuation disputes may not be heard by the Board of Review after their March Board sessions have closed. Therefore, it is important that property owners disputing their assessment file their appeal timely.

The Monitor Township Board of Review consists of three members. These three members are appointed by the Township Board in accordance with the Michigan General Property Tax Act.

If you dispute the decision of the March Board of Review, a property owner may appeal to the Michigan Tax Tribunal. The appeal must be filed with the Tribunal.  Certain appeals may require an appearance before the March Board of Review before you may appeal to the Michigan Tax Tribunal.

Virtually all the Assessment records are available to the public. Property owners may examine their property records as well as any other property in the Township.
