A tax assessment is not a bill you are required to accept. Whether it arrived from your local assessor or from the Michigan Department of Treasury, you have a right to challenge the number, and in Michigan that challenge almost always ends up in front of the Michigan Tax Tribunal. The catch is that the Tribunal runs on hard deadlines. Miss one by a single day and the assessment becomes final no matter how wrong it was. That is the reason property owners and business owners bring in a Michigan Tax Tribunal attorney early rather than after the window has closed. If you are weighing an appeal, our Michigan tax attorney team can tell you quickly whether you have a case worth filing. This guide covers what the Tribunal is, which deadline controls your situation, how a case actually moves, and where taxpayers most often lose on procedure instead of on the merits.
The Michigan Tax Tribunal is an administrative tax court. It hears disputes over property assessments and over most taxes administered by the Michigan Department of Treasury, and it issues written decisions after a hearing.
The single most useful thing to understand about it is what it is not. The Tribunal is independent of the Michigan Department of Treasury, the State Tax Commission, every local unit of government, and every local Board of Review. When you appeal to the Tribunal, you are no longer arguing with the office that assessed you. You are in front of a neutral decision maker who has authority to change the number.
It is also not the U.S. Tax Court, and a Tribunal appeal has nothing to do with an IRS Collection Due Process hearing. Michigan tax and federal tax run on completely separate tracks with separate deadlines. Settling a federal balance with the IRS does nothing to your Michigan liability, and vice versa. Taxpayers who assume one resolution covers both are the ones who get surprised by a state assessment they thought was handled.
The Tribunal is split into two divisions, Small Claims and the Entire Tribunal, and which one hears your case depends on what kind of property is involved and how much money is in dispute.
Most Tribunal cases start as property tax valuation disputes, and the path you take depends entirely on how your property is classified.
Residential, agricultural, and all other property. You must first protest to your local March Board of Review. This step is mandatory. Skip it and the Tribunal has no jurisdiction over your case, which means it gets dismissed without anyone ever looking at your valuation. If the Board of Review does not give you the result you want, you then have until July 31 of the tax year to file your petition with the Tribunal.
Commercial, industrial, and utility property, both real and personal. You have a choice. You can go to the March Board of Review first, or you can skip it and file directly with the Tribunal. Either way, your deadline is May 31 of the tax year. For commercial and industrial personal property, the direct route generally requires that a personal property statement be filed with your local unit before the March Board of Review convened.
Note how much earlier the commercial deadline falls. A commercial owner in Oakland County who waits for a residential-style July timeline has already missed the window by two months, and the Tribunal cannot fix that.
This trips up a lot of people, and some published guidance gets it wrong. Michigan local units hold Boards of Review in July and December in addition to March. Those later boards have narrow authority under MCL 211.53b. They can correct qualified errors, meaning clerical errors, mutual mistakes of fact between the assessor and the taxpayer, and errors in the measurement or calculation of the property itself. They also hear poverty exemption claims, principal residence exemption matters, and qualified agricultural exemption claims.
What they cannot do is hear an appeal based on your opinion of value. That belongs to the March Board of Review alone. The State Tax Commission has repeatedly flagged local boards that exceeded this authority. If you show up in July arguing that your building is worth less than the assessor says, you will be turned away, and the calendar will keep running.
Small Claims is the informal division. It handles cases where residential property is exclusively involved, and it also takes non-residential property when the taxable value or state equalized valuation in dispute is not more than $100,000. For non-property tax matters, Small Claims jurisdiction runs to $20,000 in dispute, a figure adjusted annually for inflation.
Small Claims hearings are telephonic and run about 30 minutes. No formal record is taken, and parties frequently represent themselves. Filing fees scale with the amount of value in dispute, and there is no filing fee at all for a Small Claims property tax appeal where the property carries a principal residence exemption of at least 50 percent.
The Entire Tribunal handles everything larger and more complex. Hearings are formal, a record is kept, and parties are typically represented by attorneys. This is where most commercial valuation disputes and larger Treasury assessments land.
If your case qualifies for Small Claims, you may still elect the Entire Tribunal instead. That choice is worth thinking about rather than defaulting. Small Claims is faster and cheaper. The Entire Tribunal gives you discovery, a formal record, and a cleaner foundation if the case might go up to the Court of Appeals.
Taxpayers usually underestimate how long this takes and overestimate how flexible the evidence rules are.
You start by e-filing or mailing a petition with the correct filing fee. The Tribunal issues a Notice of Docket Number to both sides, and the local unit or Treasury then files an answer, generally within 28 days. Discovery is not available in Small Claims except by permission of the Tribunal.
You will receive a Notice of Hearing at least 45 days before your hearing date. Then comes the deadline that quietly decides more cases than any argument does: all evidence must be submitted to the Tribunal and served on the other party at least 21 days before the hearing. Unserved evidence is generally excluded, and you will not be permitted to rely on it. People lose winnable appeals here, holding a good appraisal they never served correctly.
As the petitioner, you carry the burden of proof by a preponderance of the evidence. You have to show it is more likely than not that your number is right. The assessor does not have to prove theirs.
Depending on the Tribunal’s docket, expect roughly 12 to 18 months from filing to a final decision in Small Claims. If a Tribunal Member presides, you receive a Final Opinion and Judgment. If an administrative law judge presides, you receive a Proposed Opinion and Judgment, and either party has 20 days to file exceptions, with 14 days for the other side to respond, before a Tribunal Member issues the final decision. From there, appeals go to the Michigan Court of Appeals.
One quirk to plan for: if your case involves a value dispute and the hearing is not scheduled until after April 1 of the following year, the Tribunal will automatically add that next tax year to your case.
The Tribunal also hears appeals from Michigan Department of Treasury assessments covering income tax, sales tax, use tax, and withholding. The deadlines here are completely different from property tax deadlines, and this is where outdated advice does the most damage.
Before issuing a final assessment, Treasury generally sends a Notice of Intent to Assess, and you have a limited window to request an informal conference. That conference is worth using. It is the last stop before the numbers harden.
Once a final assessment is issued, MCL 205.22(1) gives you a choice. You may appeal to the Michigan Tax Tribunal within 60 days or to the Michigan Court of Claims within 90 days.
Pay attention to that 60-day figure. The statute previously set the Tribunal window at 35 days, and it was amended by 2015 PA 79 effective March 2016. A significant amount of published Michigan tax content still cites the old 35-day number. If you are working from an article, a template, or even an older state publication, verify the deadline against the current statute before you rely on it.
Two more conditions matter. The uncontested portion of the assessment must be paid as a prerequisite to appealing. And under MCL 205.22(5), an assessment becomes final, conclusive, and not subject to further challenge 90 days after issuance, with no refund available to a taxpayer who did not appeal properly.
It is also worth knowing that Michigan’s collection statute of limitations is generally six years from assessment under MCL 205.27a, not the ten-year federal collection window. Michigan’s flat income tax rate is 4.25% for the 2026 tax year. Michigan also operates its own Offer in Compromise program, entirely separate from the federal program run by the IRS.
Consider a small manufacturer who owns a commercial building in Oakland County. In February, the assessment notice arrives showing a taxable value that jumped sharply after a neighboring parcel sold at an unusually high price. The owner believes the assessment overstates the building’s true cash value by several hundred thousand dollars, largely because the assessor’s records show more usable square footage than the building actually has and do not reflect a section that has been unusable for years.
Because the property is classified commercial real, the owner has two viable paths. Going to the March Board of Review first is often worth doing because a documented measurement error is exactly the kind of thing a local board can correct quickly and cheaply. But the owner cannot let that process run past May 31, because that is the Tribunal filing deadline for commercial property regardless of what the Board of Review is doing.
Assume the board makes only a partial adjustment. The owner files a Tribunal petition before May 31. Because the value in contention exceeds $100,000, the case proceeds in the Entire Tribunal, and the owner’s representative assembles an independent appraisal, a measured floor plan documenting actual square footage, engineering documentation of the unusable section, and comparable sales reflecting the building’s real condition. All of it is served on the local unit well before the 21-day evidence deadline. Cases like this often resolve by consent judgment before a hearing ever happens, once the assessor sees the documentation.
This example is illustrative only and does not describe an actual client matter. Outcomes depend entirely on the specific facts, evidence, and property involved. Prior results do not guarantee a similar outcome.
A few patterns account for most avoidable losses at the Tribunal.
Levy & Associates is a Michigan-based firm with our primary office in Lathrup Village, in the heart of Oakland County. Our team includes licensed attorneys, CPAs, enrolled agents, and former IRS revenue officers. That last credential matters more than people expect in state matters because the professionals who once worked collection cases from the government side know how assessments get built and where the weak points usually are.
For property disputes, the work is largely evidentiary. We assess whether your number is genuinely out of line, identify what documentation will actually move it, and make sure every filing and service deadline is met. For Treasury assessments, we handle the informal conference stage where many disputes resolve before a final assessment ever issues, and we take the case to the Tribunal when it does not.
We also handle the surrounding problems. If a Michigan or federal balance has already moved into collection, we work on tax audits and appeals alongside the Tribunal case rather than treating them as separate emergencies. Clients throughout the Detroit metro can reach our Lathrup Village office directly, and if your dispute is with an assessor outside Michigan, our general guide to disputing a tax assessment covers the process more broadly.
One important limit on our scope: Levy & Associates handles civil tax matters only. We do not represent clients in criminal tax matters of any kind. If your situation involves a criminal investigation or referral, you need criminal defense counsel, and we will tell you that directly rather than take the case.
You are allowed to represent yourself, and the Small Claims Division is built for that. Hearings are informal and telephonic, and plenty of homeowners handle their own residential appeals successfully. Representation tends to matter when the dollars are larger, when the property is commercial or industrial, when the case belongs in the Entire Tribunal, or when the dispute involves a Treasury assessment rather than a property value. The other factor is evidence. Tribunal cases are usually won on documentation and appraisal work, not argument, and that is where professional help changes outcomes.
Tribunal filing fees scale with the amount of value in dispute, and there is no filing fee for a Small Claims property tax appeal on a property with a principal residence exemption of at least 50 percent. The real cost drivers are appraisal and professional fees. The way to think about it is annual, not one-time. A corrected taxable value carries forward, so a reduction that looks modest in a single year compounds across every year you own the property. We look at that math with you before recommending a filing, and we will tell you when an appeal is not worth the cost.
It depends on which kind of appeal you are filing. For a Treasury assessment, MCL 205.22 requires you to pay the uncontested portion of the assessment as a prerequisite to appealing to the Tribunal, though you do not have to pay the contested portion to proceed there. The Court of Claims route works differently. For property tax appeals, your tax bills continue to come due on the normal schedule while the case is pending, and an adjustment is handled afterward if you prevail. Interest and penalties can continue to accrue on unpaid amounts, so it is worth getting specific advice about your situation rather than assuming the appeal pauses everything.
Usually the honest answer for that tax year is no. Tribunal deadlines are jurisdictional, which means the Tribunal has no power to hear a late petition even if your assessment is clearly wrong. That said, there are often other moves available. If the problem is a clerical error, a mutual mistake of fact, or an error in the measurement of your property, the July or December Board of Review may be able to correct it for the current year and one prior year. And a missed deadline for one tax year does not affect the next one, so the priority becomes preparing properly for the next cycle. It is worth a conversation before you conclude nothing can be done.
Plan on roughly 12 to 18 months from filing to a final decision, depending on the Tribunal’s docket. You will receive a Notice of Hearing at least 45 days in advance. The deadline that genuinely matters meanwhile is the 21-day mark before your hearing, when all evidence must be both filed with the Tribunal and served on the other party. Evidence that is not properly served is generally excluded. Many cases also settle by consent judgment before a hearing ever occurs, so keep your documentation organized and be ready to respond if the other side opens a discussion.
If you are facing a disputed Michigan property assessment or a Michigan Department of Treasury assessment, the team at Levy & Associates is ready to help. Our attorneys, CPAs, and former IRS revenue officers understand exactly how these assessments get built and what evidence actually moves them, because many of us worked on the government side of these cases. The most valuable thing you can do right now is find out which deadline applies to you before it passes. Call us at 800-TAX-LEVY or contact us online for a free consultation.
