Rate Breakdown

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

How Property Tax Works in Sanilac County

In Sanilac County, your property tax bill is calculated based on two primary figures: the Taxable Value (TV) of your property and the local millage rates. The assessment process begins with the local assessor, who determines the Assessed Value (AV)—typically 50% of the property's estimated market value. However, under Michigan law, your taxes are based on the Taxable Value, which is capped by the Consumer Price Index (CPI) or 5%, whichever is lower, unless there is a transfer of ownership.

The total millage rate is a combination of levies from the county, local townships or cities, school districts, and special assessments. One mill is equal to $1 of tax for every $1,000 of Taxable Value. These rates are voted upon by residents or authorized by state mandates to fund essential public services, including law enforcement, road maintenance, and local education systems.

Available Exemptions

Michigan offers several exemptions to help reduce the tax burden for eligible property owners. It is essential to file the necessary documentation with your local assessor’s office to qualify.

• Principal Residence Exemption (PRE): Also known as a homestead exemption, this allows homeowners to exempt their primary residence from a portion of local school operating taxes.
• Disabled Veterans Exemption: Veterans who have been honorably discharged with a service-connected disability may be eligible for a 100% property tax exemption on their primary residence.
• Poverty Exemption: Residents who meet specific federal poverty income guidelines may apply for a hardship exemption to reduce or eliminate their tax liability.
• Senior/Disabled Deferments: Certain seniors and citizens with disabilities may qualify to defer the payment of their summer property taxes until the following February without penalty.

Payment Schedule & Deadlines

Property taxes in Sanilac County are generally billed in two cycles: the Summer tax bill and the Winter tax bill. Summer taxes are typically mailed in July and are due by September 14th. Winter taxes are mailed in December and are due by February 14th of the following year.

Payments must be received or postmarked by the due date to avoid interest and penalties. If taxes remain unpaid after February 28th, the collection process shifts to the Sanilac County Treasurer’s office. At this point, additional interest and administrative fees accrue monthly, and delinquent properties may eventually be subject to foreclosure proceedings if taxes remain unpaid for an extended period.

Appealing Your Assessment

If you believe your property’s assessment is inaccurate, you have the right to appeal. The process begins at the local level by appearing before the March Board of Review. You must provide evidence to support your claim, such as comparable sales data, recent appraisals, or documentation of structural issues. If you are dissatisfied with the local board's decision, you may further appeal to the Michigan Tax Tribunal. It is recommended to contact your local assessor’s office for specific meeting dates and filing deadlines.
