Rate Breakdown

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

How Property Tax Works in Mason County

In Mason County, property taxes are administered through a structured assessment process governed by Michigan state law. Every property is assigned an Assessed Value (AV), which is intended to represent 50% of its true cash value. However, the amount you actually pay is based on the Taxable Value (TV). Under Michigan’s Proposal A, the Taxable Value is capped and cannot increase by more than 5% or the rate of inflation (whichever is lower) from the previous year, unless there is a change in ownership or significant physical improvements made to the property.

Your local tax bill is calculated by multiplying the Taxable Value by the total millage rate applicable to your specific location. A "mill" represents $1.00 of tax for every $1,000 of Taxable Value. These millage rates are determined by various taxing authorities, including the county, townships or cities, and local school districts, to fund essential public services such as emergency response, road maintenance, and public education.

Available Exemptions

Michigan provides several exemptions that can significantly reduce the property tax burden for eligible Mason County residents. It is essential to apply for these through your local assessor’s office to ensure you are receiving all applicable benefits. Key exemptions include:

• Principal Residence Exemption (PRE): Also known as the "homestead" exemption, this allows homeowners to exempt their primary residence from the local school operating tax, typically saving about 18 mills.
• Disabled Veterans Exemption: Honorably discharged veterans who are 100% disabled as a result of military service may be eligible for a total exemption from property taxes on their primary home.
• Poverty Exemption: Homeowners who meet specific income and asset requirements set by their local municipality may qualify for a partial or full reduction of their property taxes.
• Senior Citizen Credits: While not a direct local exemption, the Michigan Homestead Property Tax Credit allows seniors to claim a credit on their state income tax return to offset local property tax costs.

Payment Schedule & Deadlines

Mason County property taxes are split into two annual billing cycles: Summer and Winter. Adhering to these deadlines is critical to avoid costly penalties and interest charges.

• Summer Taxes: These bills are typically mailed on July 1 and are due by September 14. Summer taxes primarily fund county operations and state education taxes.
• Winter Taxes: These bills are generally mailed on December 1 and are due by February 14. Winter taxes often cover township-level services and special assessments.

If a deadline falls on a weekend or a legal holiday, payments are usually accepted on the following business day. On March 1 of each year, all unpaid taxes are classified as delinquent and are transferred to the Mason County Treasurer’s Office, where additional interest and collection fees are applied.

Appealing Your Assessment

If you believe your property’s Assessed Value exceeds 50% of its true market value, you have the right to file an appeal. Every February, Mason County property owners receive a Notice of Assessment, Taxable Valuation, and Property Classification. If you disagree with the valuation, you must first appeal to the local March Board of Review. This step is mandatory for residential property owners before they can escalate the matter. During the hearing, you should present objective evidence, such as a recent professional appraisal or data on comparable property sales in your area. If the Board of Review denies your request, you may then file a petition with the Michigan Tax Tribunal.
