Michigan has one of the most structured property tax appeal systems in the Midwest. For commercial property owners — whether you own industrial warehouses, office buildings, or multifamily properties — knowing how this system works is essential to protecting your bottom line.
Overview: Michigan's Two-Level Appeal System
Michigan property tax appeals operate on two main levels. The first is the local Board of Review, which meets every March. The second is the Michigan Tax Tribunal, a state-level administrative court that handles both simple and complex property tax disputes. Each level has its own rules, deadlines, and procedures.
For most commercial properties, the Board of Review is a required first step. You cannot file with the Tax Tribunal unless you have first appeared before (or filed a protest with) the local Board. This sequential requirement is one of the most important things to understand — and one of the most common mistakes property owners make. For a broader overview of the process across all three states, see our property tax appeal process resource.
Step 1: Review Your Assessment Notice
Assessment notices are mailed in February. Your notice will show two key figures: the assessed value (which should be 50% of true cash value) and the taxable value (which is capped by Proposal A unless the property was recently sold). If either number seems too high, you likely have grounds for an appeal.
Pay close attention to uncapping events. When a Michigan property sells, the taxable value is "uncapped" — meaning it resets to the full assessed value. This can cause a dramatic increase in property taxes. If you recently purchased your property, see our guide on Michigan uncapping to understand your options.
Step 2: File a Protest with the Board of Review
The March Board of Review is your first formal opportunity to challenge your assessment. Each municipality sets its own hearing schedule, but the window is typically during the first two weeks of March. You can appear in person, send a representative, or submit a written protest by letter.
The Board of Review has authority to adjust both assessed value and taxable value. For straightforward cases — where the assessor made a clear factual error, like using incorrect square footage — the Board can often resolve the issue without the need to escalate. However, for larger commercial properties with complex valuation disputes, the Board of Review is usually a stepping stone to the Tax Tribunal.
Important: Even if you do not expect the Board of Review to grant a reduction, you should still file a protest. This preserves your right to file with the Michigan Tax Tribunal.
Step 3: File a Petition with the Michigan Tax Tribunal
If the Board of Review denies your protest or does not reduce your assessment enough, you can file a petition with the Michigan Tax Tribunal. There are two divisions: the Small Claims Division and the Entire Tribunal. Both have a filing deadline of May 31st.
The Small Claims Division offers a simpler, less formal process. Hearings are typically shorter, the rules of evidence are relaxed, and property owners can represent themselves more easily. However, decisions from the Small Claims Division are final — there is no appeal.
The Entire Tribunal handles larger and more complex cases. It follows formal rules of evidence, allows discovery, and may involve expert witnesses. Decisions from the Entire Tribunal can be appealed to the Michigan Court of Appeals. For high-value properties in major counties like Wayne County, Oakland County, or Kent County, the Entire Tribunal is often the more effective option.
What Evidence Do You Need?
The quality of your evidence often determines the outcome of your appeal. The Michigan Tax Tribunal relies heavily on the three standard approaches to value: the income approach, the sales comparison approach, and the cost approach. For most commercial properties, the income approach is the most relevant.
Strong evidence includes actual income and expense statements for your property, recent sales of comparable commercial properties, independent appraisals, and documentation of property-specific issues (vacancy, deferred maintenance, environmental concerns). The assessor will also present evidence, so you need to be prepared to respond to their methodology. Our guide on property tax appeal evidence covers this in detail.
Cap rate disputes are particularly common in Michigan Tax Tribunal cases. The assessor may apply a cap rate from a published survey that does not reflect the risk profile of your specific property. You can present evidence of market-derived cap rates from actual comparable sales to argue for a more accurate valuation.
Settlements and Stipulations
A significant percentage of Michigan Tax Tribunal cases settle before going to a full hearing. Once a petition is filed, the assessor's office may be willing to negotiate a stipulated value that both parties agree on. This can save months of litigation and still produce meaningful tax savings.
Settlements are particularly common when the property owner presents strong evidence early in the process. An experienced property tax consultant can help you identify the right settlement range and negotiate effectively.
