Many commercial property owners in Michigan do not realize that the Board of Review, the local body convened each March to hear assessment protests, is entirely optional for their property type. Since a 2007 amendment to the Michigan General Property Tax Act, commercial and industrial owners have held the right to file directly with the Michigan Tax Tribunal, skipping the Board of Review entirely. For most significant commercial disputes, that direct route is the strategically superior choice.
The statute is unambiguous on the point. As practitioners in this area have noted, commercial and industrial real properties no longer have to petition the March Board of Review. These appeals can be made directly to the Michigan Tax Tribunal on or before May 31. The choice of path, however, is an either/or decision for a given tax year. A petitioner who elects direct MTT filing forfeits the ability to appear before the Board of Review for that year, and vice versa. The election is made by whichever action is taken first.
Why the Board of Review Falls Short for Complex Commercial Properties
The Board of Review serves a legitimate function in the broader assessment appeal system. For straightforward factual disputes, such as a building square footage recorded incorrectly, a property feature that does not exist, or a simple misclassification, a brief Board appearance can resolve the matter quickly without Tribunal involvement. There are also situations where an informal conversation with the local assessor's office, facilitated through the Board process, produces a corrected assessment before any formal proceeding is necessary.
For commercially significant properties where the dispute centers on income approach methodology, market rent assumptions, cap rate selection, or the treatment of vacancy and expenses, the Board of Review is structurally limited. Board members are typically local volunteers without specialized training in income capitalization analysis. A thirty-minute hearing is not sufficient to present and evaluate the kind of evidence that drives meaningful reductions on a multi-million dollar commercial asset. The Board's authority to adjust assessed values exists, but the practical capacity to evaluate complex valuation arguments is generally not present.
Beyond the technical limitations, there is a timing advantage to direct MTT filing that is often overlooked. Assessment notices arrive in late February. Filing directly by May 31 provides roughly thirteen weeks to build the evidence package, assemble income and expense documentation, and develop a rigorous income approach analysis. A Board of Review appearance, by contrast, happens in March, often within days of receiving the assessment notice. The quality of the analysis that can be assembled in that compressed window is fundamentally different from what is achievable with the full pre-MTT period.
What Direct MTT Filing Accomplishes Strategically
Filing directly at the Tribunal positions the dispute before professionals who evaluate income approach analyses routinely. MTT hearing officers understand direct capitalization methodology, recognize market-derived cap rates, and apply the True Cash Value standard that governs Michigan assessments. The evidentiary framework is formal, which means that a well-constructed analysis carries the weight it deserves, and an assessor's unsupported value conclusion faces genuine scrutiny.
There is also a dynamic worth understanding about smaller jurisdictions. Local political considerations occasionally influence Board of Review outcomes in ways that have nothing to do with valuation evidence. A large commercial taxpayer in a township where the assessor has a close relationship with elected officials may find the Board less receptive than a neutral Tribunal hearing officer in Lansing. Direct MTT filing removes that variable entirely.
For the same reasons, direct filing avoids the scenario in which a Board appearance produces a nominal reduction that does not reflect the property's true over-assessment, creating a record that could later complicate the Tribunal proceeding.
The Evidence Package Required for Entire Tribunal Proceedings
Commercial MTT petitions that proceed in the Entire Tribunal, the formal division appropriate for significant disputes, require a substantive evidence package. The Tribunal will not accept evidence submitted after applicable deadlines, and cases without adequate support tend to settle at or near the assessed value. The following categories of evidence form the foundation of a credible commercial presentation:
- Income and expense statements: Three years of operating statements allow the Tribunal to see the property's financial history and support a reconstructed stabilized net operating income.
- Current rent roll and lease documents: These establish actual occupancy, current rental rates, lease terms, and any concessions. Where contract rents differ from market rents, this documentation drives the analysis.
- Cap rate evidence: Capitalization rates must be grounded in recognized sources. Investor surveys from RealtyRates, RERC, PwC, and CoStar provide defensible benchmarks, and comparable sales analyses support market-derived rates directly extracted from transactions.
- Comparable sales: Arms-length sales of similar commercial properties in the relevant market, typically within the past 24 months, establish the context for both the sales comparison approach and cap rate support.
- Condition documentation: Photographs, inspection reports, deferred maintenance logs, and capital expenditure records substantiate any physical or functional obsolescence adjustments.
In the Entire Tribunal, the parties exchange evidence in advance of the hearing according to a schedule established by the Tribunal. Testimony is taken under oath, and the formal record supports a full right of appeal to the Michigan Court of Appeals. That appellate pathway is available only in Entire Tribunal proceedings, which is one reason why consequential commercial disputes belong there rather than in Small Claims.
The 5 Percent Problem
Industry analysis suggests that somewhere between 30 and 60 percent of commercial properties in Michigan carry assessments above the True Cash Value standard. Despite that range of potential over-assessment, roughly 5 percent of commercial owners file appeals in any given year. The gap between the scale of the problem and the rate of action reflects several factors, but one of them is the mistaken assumption that the Board of Review is a prerequisite and that the process is more cumbersome than it is.
Direct MTT filing, combined with contingency-based representation that eliminates upfront cost, removes the two most common barriers. The petition is the starting point, not the endpoint. Most Entire Tribunal cases resolve through settlement before a formal hearing, often with meaningful reductions, precisely because a well-supported income approach creates negotiating leverage that assessors cannot easily dismiss.
The Deadline Governs Everything
The May 31 deadline for commercial MTT petitions is absolute. The Tribunal does not grant extensions for any reason, and the courts have consistently declined to provide equitable relief for missed deadlines. Filing on May 30 is prudent. Filing on May 31 carries risk. Waiting until the final days to begin assembling the evidence package is a pattern that consistently produces weaker positions than cases initiated promptly after the February assessment notice.
The structural advantage of direct MTT filing is only realized when the timeline is managed with discipline from the assessment notice forward.
