How Property Tax Works

Property taxes in Marquette County, Michigan fund essential local services including schools, county government operations, libraries, fire protection, and various special districts. The county uses a millage-based system where property taxes are calculated by multiplying the taxable value by the applicable mill rate. For the 2025 tax year, the county-wide rate is 28.2841 mills (reduced by 0.0053 mills from the previous year), though actual rates vary significantly by location within the county due to different combinations of special taxing districts.

Property tax bills in Marquette County are issued twice yearly on July 1st and December 1st by individual cities and townships. The actual tax rate you pay depends on your specific location within the county, as different municipalities and special districts (such as school districts, library districts, and fire districts) levy their own millages on top of the base county rate. This means two properties of equal value in different areas of Marquette County may have substantially different tax bills based on their local taxing jurisdictions.

Supplemental Tax Bills

Supplemental taxes in Marquette County are additional property tax assessments that occur when there are changes to property ownership, new construction, or significant improvements during the tax year. These supplemental bills are issued when the assessed value of a property increases due to new construction completion, major renovations, or corrections to the assessment roll after the regular tax roll has been finalized.

Supplemental taxes are calculated by applying the current mill rate to the difference between the new assessed value and the previous assessed value, prorated for the portion of the tax year remaining. For example, if you complete a $50,000 home addition in October that increases your taxable value by $25,000, you would receive a supplemental tax bill for the remaining months of that tax year calculated on the additional $25,000 taxable value at your local mill rate.

Escrow & Property Taxes

Most mortgage lenders in Marquette County require borrowers to establish an escrow account for property tax payments, especially when the loan-to-value ratio exceeds 80%. Your lender collects 1/12th of your estimated annual property tax bill with each monthly mortgage payment, holding these funds in escrow until tax payments are due. Given Marquette County's semi-annual billing schedule (July 1st and December 1st), your lender will typically make two payments per year to your local treasurer.

It's important to monitor your escrow account annually, as property tax changes can create shortages or surpluses. When your property taxes increase due to assessment changes or millage increases, your lender may require you to make up any escrow shortage and adjust your monthly payment accordingly. You should receive an annual escrow analysis statement showing the account activity and any required payment adjustments. Always verify that your lender is paying the correct amount by comparing their payments to your actual tax bills from the city or township treasurer.

Frequently Asked Questions

Q: When are property taxes due in Marquette County for 2025? A: Tax bills are mailed July 1st and December 1st each year. The first installment is due by September 14th. Taxes remain payable to your local city or township treasurer until March 1st of the following year, after which they become delinquent and transfer to the County Treasurer.

Q: What tax credits are available and do I need to apply? A: The Principal Residence Exemption (PRE) is the primary tax credit, exempting your primary residence from up to 18 mills of school operating taxes. This credit requires application and is NOT automatic. You must file the application with supporting documents as specified by the assessor.

Q: How does the Homestead exemption work? A: Michigan's homestead provision caps assessment increases at 5% annually or the inflation rate, whichever is lower, for properties that qualify. This limits assessment growth rather than reducing market value. You must file for this protection - it's not automatically applied.

Q: How often are properties reassessed? A: Properties are assessed annually, with assessments based on 50% of true cash value. The assessment date is December 31st of the previous year. You can appeal your assessment to the local Board of Review, typically meeting in March.

Q: What are the penalties for late payment? A: Late payment penalties and interest apply after March 1st when taxes become delinquent and transfer to the County Treasurer. Contact the County Treasurer's office for specific penalty rates and collection procedures.

Q: Can I pay my property taxes online? A: Payment options vary by municipality. Contact your specific city or township treasurer to inquire about online payment availability and accepted payment methods for current taxes.

Q: Why is my tax rate different from my neighbor's? A: Tax rates vary within Marquette County based on the combination of special taxing districts serving your property. Different school districts, fire districts, library districts, and municipal boundaries create varying total millage rates across the county.

Q: What triggers a supplemental tax bill? A: Supplemental taxes are issued for new construction completion, major property improvements, ownership changes that reveal missed assessments, or corrections to the assessment roll after the regular tax bills are mailed.
