Wayne County Commercial Property Tax Appeals

We represent owners of all commercial property types in Wayne County, including retail, office, industrial, multifamily, healthcare, and more — across Detroit, Dearborn, Livonia, Westland, Canton, and every other Wayne County community. Each property type requires a different valuation approach, and our team has the experience to apply the right methodology whether we're appealing a strip mall in Westland or a warehouse in Romulus. We also handle special-use properties such as self-storage facilities, auto dealerships, and medical office buildings.

The deadline is May 31 of the tax year. This is the Michigan Tax Tribunal filing deadline and applies to all Wayne County commercial properties. Once it passes, you cannot appeal your assessment for that year. Because Wayne County has so many municipalities, assessment notices may arrive at different times, so it is important to track the calendar rather than wait for a notice. We recommend beginning your review well before the deadline to allow time for gathering property data and building your case. Check our deadline guide or read about Michigan property tax deadlines for 2026 for more details.

When a commercial property sells in Wayne County, the taxable value uncaps to the full State Equalized Value (SEV). This often results in a significant tax increase for the new owner — sometimes doubling or even tripling the prior tax bill depending on how long the previous owner held the property. Even after uncapping, the assessed value can be challenged if it's above fair market value. In fact, post-purchase appeals are among the most common and successful cases we handle in Wayne County. Buyers who act quickly can often secure a reduced assessment in the same year they acquire the property. Learn more about Michigan uncapping.

EPTA works on a contingency basis — you pay nothing unless we successfully reduce your assessment and save you money. There are no upfront fees, no retainers, and no risk. If we don't save you money, you owe us nothing. This fee structure means our incentives are fully aligned with yours: we only succeed when you see real tax savings.

A strong Wayne County appeal typically relies on three categories of evidence: comparable sales data showing what similar properties have sold for, income and expense information demonstrating the property's actual earning capacity, and documentation of the property's physical condition including deferred maintenance, vacancy, or functional obsolescence. The Michigan Tax Tribunal expects credible, well-organized evidence that directly supports a lower true cash value. Our team compiles and presents this evidence on your behalf so you do not have to navigate the process alone. For a deeper look at what you'll need, read our property tax appeal evidence guide.

While Michigan law allows property owners to represent themselves before the Tax Tribunal, Wayne County commercial appeals involve significant procedural requirements, valuation analysis, and negotiation with experienced municipal attorneys. A misstep in evidence submission or valuation methodology can undermine an otherwise valid claim. Professional representation ensures your case is presented with the rigor the Tribunal expects, and on a contingency basis there is no financial downside to working with an expert. Many owners who attempt a DIY appeal ultimately leave savings on the table. Learn more about DIY vs. professional appeals to decide which approach is right for you.

Yes, and in many cases you should. When a commercial property changes hands in Wayne County, the taxable value uncaps to the current assessed value, which often triggers a large tax increase. New owners have every right to challenge the resulting assessment if it exceeds the property's true cash value. Filing promptly after a purchase is especially important because the uncapping adjustment may be based on outdated or inaccurate data. Many buyers discover significant savings by appealing in their first year of ownership. Read more about appealing property taxes after a purchase to understand your options.
