Tax Records & Assessments in Michigan

In Michigan, property tax records and assessments are critical tools used to determine local revenue for public schools, fire departments, police, road maintenance, and municipal services. These records are publicly accessible and maintained at the local government level, typically by the township or city assessor and treasurer.

What Are Property Tax Records?

Property tax records are the official public ledger of a property’s financial obligations and valuation. They serve as a comprehensive history that includes the legal owner, a breakdown of annual tax amounts, payment history, and any applied exemptions.

Key information included in Michigan tax records includes the following:

• Owner names and address

• Parcel identification number (PIN)

• Property description and use classification

• Assessed value

• State Equalized Value (SEV)

• Taxable value

• Millage rates and actual tax bill

• Homestead and other exemptions

• Tax payment history and delinquencies

What Is a Property Tax Assessment?

An assessment is the local government’s official determination of a property’s value for taxation purposes. In Michigan, an assessment does not necessarily reflect the full market value; instead, it is a calculation used to ensure that the tax burden is distributed fairly across the community.

How Property Assessments Work in Michigan

Every year, local assessors in Michigan determine a property’s TCV (true cash value), that is, the expected selling price of the property. By law, the assessed value (AV) must be precisely 50% of the TCV.

To determine these values, local assessors typically use the following methods:

• Market Approach: Comparing your home to recent sales of similar properties in your neighborhood

• Cost Approach: Calculating the cost to replace the structure, minus depreciation

• Mass Appraisal: Using statistical models to adjust values across entire neighborhoods simultaneously

How Property Taxes Are Calculated in Michigan

Michigan property taxes are calculated using this formula:

Annual Property Tax = (Taxable Value ÷ 1,000) × Millage Rate

The taxable value is the lesser of the assessed value and the capped value of your property. Note that the assessed value is always 50% of your home’s true cash value (market value), while the capped value is the previous year’s taxable value adjusted for the inflation rate (plus any new additions like a deck or garage). Millage rates are determined by various local authorities, including cities, counties, and school districts.

Per Proposal A of 1994, the defining feature of the Michigan tax system is the cap on increases in taxable value. As long as you own your home, the taxable value can only increase annually by whichever is lower of these two factors:

• The rate of inflation (the Inflation Rate Multiplier)

• 5%

Note that the year after a property is sold, the taxable value uncaps and jumps up to match the assessed value, leading to a significant tax increase for the new owner.

The Michigan government website provides a property tax estimator that allows users to estimate their property taxes and compare them with those of other local units in the state.

What Affects Your Property’s Assessed Value?

Although the taxable value is capped, your property’s assessed value can fluctuate based on the following factors:

• Location or Neighborhood Sale Trends: Neighborhood demand and recent nearby sales

• Additions: New decks, finished basements, or additional bathrooms

• Land Characteristics: Lot size, water frontage, or proximity to amenities

• Age and Quality: The condition of the structure and the quality of construction materials used.

Why Your Property Tax Bill Might Increase (or Decrease)

Your property tax bill can change even if your home’s value remains steady due to the following factors:

• Millage Increases: If voters approve a new school or library bond, the tax rate (mills) increases.

• Loss of Exemption: Losing an exemption adds to your tab bill. For example, if you move out and turn the home into a rental, you lose the Principal Residence Exemption (PRE), which adds 18 mills back onto your bill.

• Inflation: Even with the “cap,” your taxable value typically rises annually by the rate of inflation.

• Additions: New construction or remodeling increases assessed and taxable values.

• Cap Removal: A home sale “uncaps” the taxable value, resetting it to match the assessed value (50% of market value).

How to Review Your Tax Assessment for Accuracy

When you receive a notice of assessment from local authorities, you can review it for accuracy by checking for:

• Factual Errors: You should check for incorrect square footage, bedroom counts, or acreage.

• Exemption Status: Check to ensure your exemptions (if applicable) are appropriately applied.

• Comparable Sales: Check to verify that the “True Cash Value” listed on the notice matches what similar homes in your area actually sold for.

How to Appeal a Property Tax Assessment in Michigan

If you believe your property tax assessment is inaccurate, you can act by submitting an appeal to the:

• March Board of Review : Residential owners can appeal their property tax assessment to the March Board of Review. They are required to present evidence (such as a recent appraisal or photos of structural damage) to their local board.

• Michigan Tax Tribunal : If the Board of Review denies your request, you can escalate the appeal to this state-level court. However, you must have appeared before the local board first.

How to Find Property Tax Records & Assessments in Michigan

Tax records are usually available on the city, township, or county website. For example, many counties (like Oakland, Kent, or Washtenaw) offer searchable online portals for users to find property tax records in Michigan. Alternatively, you can contact the local assessor’s or treasurer’s office in the area where the property is located.
