Rate Breakdown

Property taxes in Iosco County are calculated by multiplying the assessed value (minus exemptions) by the total local millage rate.

How Property Tax Works in Iosco County

In Iosco County, property taxes are calculated based on two primary figures: the Taxable Value (TV) of your property and the local millage rates. The assessment process begins with your local assessor, who determines the State Equalized Value (SEV) annually. Under Michigan law, your Taxable Value cannot increase by more than 5% or the rate of inflation, whichever is lower, unless there are physical improvements to the property or a transfer of ownership occurs.

The total tax bill is derived by multiplying your Taxable Value by the combined millage rate of your local jurisdiction, which includes levies for county operations, schools, townships, and special services. One mill is equal to $1 of tax for every $1,000 of Taxable Value. Because these rates fluctuate based on local voter-approved initiatives, your total tax liability may change even if your property's value remains stable.

Available Exemptions

Michigan offers several programs to reduce the tax burden for qualifying residents. These exemptions are designed to provide relief based on residency and specific personal circumstances:

• Principal Residence Exemption (PRE): Homeowners who occupy their property as their primary residence may exempt the home from a portion of local school operating taxes.
• Disabled Veterans Exemption: Veterans with a 100% service-connected disability rating are eligible for a 100% property tax exemption on their primary residence.
• Poverty Exemption: Residents who meet specific income and asset guidelines established by their local Board of Review may qualify for a partial or full reduction in property taxes.
• Senior/Disabled Deferment: Qualifying seniors or individuals with disabilities may be eligible to defer the payment of summer property taxes until the following February without penalty.

Payment Schedule & Deadlines

Property taxes in Iosco County are generally billed in two cycles: the Summer tax bill and the Winter tax bill.

• Summer Taxes: Typically mailed in July and due by September 14th without penalty.
• Winter Taxes: Typically mailed in December and due by February 14th of the following year.

Failure to pay by these deadlines results in late penalties and interest, which accrue monthly. If taxes remain unpaid after February 28th, the collection process moves to the Iosco County Treasurer’s office, where additional administrative fees are added. Continued delinquency can eventually lead to tax foreclosure proceedings.

Appealing Your Assessment

If you believe your property’s assessed value is inaccurate, you have the right to appeal. The process begins at the local level with the March Board of Review. You must first schedule an appointment to present evidence—such as recent appraisals or comparable sales data—demonstrating that your assessment does not reflect the fair market value of your property. Should you remain dissatisfied with the Board of Review’s decision, you may file a subsequent appeal with the Michigan Tax Tribunal.
