Rate Breakdown

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

How Property Tax Works in Mackinac County

Understanding your property taxes in Mackinac County begins with how your property is valued and how millage rates are applied. Each year, your local assessor determines the True Cash Value (market value) of your property as of December 31st of the preceding year. This value is then capped by Proposal A of 1994, which dictates that your Assessed Value (AV) cannot exceed 50% of the True Cash Value. Your Taxable Value (TV), the figure used to calculate your actual tax bill, is initially the same as your AV but is capped by both Proposal A and the Headlee Amendment. This means your TV can only increase by the rate of inflation or 5%, whichever is lower, unless there’s a change of ownership. When a property changes ownership, the Taxable Value is "uncapped" to match the Assessed Value in the year following the transfer.

Millage rates are then applied to your Taxable Value. A "mill" represents $1 for every $1,000 of Taxable Value. Various taxing authorities—such as the county, local townships, school districts, and libraries—each levy their own millage rates. Your total property tax bill is the sum of these individual millage rates multiplied by your property's Taxable Value.

Available Exemptions

Several exemptions can help reduce your property tax burden in Mackinac County. The most common is the Principal Residence Exemption (PRE), often referred to as the "Homestead Exemption." If you own and occupy your home as your primary residence, you may qualify for this exemption, which exempts your home from the 18 mills levied for local school operating purposes.

• Principal Residence Exemption (PRE): Reduces your Taxable Value by 18 mills for school operating taxes if your property is your primary residence.
• Veteran's Exemption: Eligible disabled veterans or their unremarried surviving spouses may qualify for a full or partial exemption from property taxes. Specific criteria regarding service-related disability ratings apply.
• Poverty Exemption: Homeowners meeting specific income and asset guidelines, and residency requirements, may apply for a poverty exemption through their local township or city assessor's office. Eligibility and application deadlines vary by local unit within Mackinac County.

It's important to apply for these exemptions through your local assessor's office and ensure all documentation is submitted by the specified deadlines.

Payment Schedule & Deadlines

Property taxes in Mackinac County are typically collected in two installments: Summer taxes and Winter taxes.

• Summer Taxes: Usually billed around July 1st, with a due date typically in mid-September without penalty. These often include county, school operating, and township operating millages.
• Winter Taxes: Usually billed around December 1st, with a due date typically in mid-February of the following year without penalty. These often include school debt, special assessments, and remaining local levies.

Specific due dates and late payment penalties can vary slightly by your local township or city within Mackinac County. It's crucial to consult your tax bill or contact your local treasurer's office for exact dates. Failure to pay by the deadlines will result in late penalties and interest charges. Unpaid taxes are ultimately turned over to the Mackinac County Treasurer's Office for collection, which can lead to further penalties, forfeiture, and eventually foreclosure if taxes remain delinquent.

Appealing Your Assessment

If you believe your property's assessed value is incorrect, you have the right to appeal. The first step in the appeal process is to review your annual Assessment Notice, which is mailed in late February or early March. This notice provides your property's assessed and taxable values for the current year.

Your initial opportunity to appeal is to your local unit's Board of Review (BOR). Each township and city in Mackinac County holds BOR meetings in March. You must schedule an appointment or appear before your local BOR during their designated appeal dates to present your case. It is essential to provide evidence to support your claim that the assessment is inaccurate, such as comparable sales data for similar properties in your area.

If you are not satisfied with the Board of Review's decision, you may then appeal to the Michigan Tax Tribunal (MTT). For residential properties, appeals to the MTT must generally be filed by July 31st of the current tax year, or within 35 days of the BOR's decision, whichever is later. Strict adherence to these deadlines is critical, as late appeals are typically not accepted.
