Iron Mountain, Michigan

Michigan city · Dickinson County · About 7,500 people

Iron Mountain owes its growth to ore. The Chapin Mine began producing in 1880, eventually turned out about 27 million tons, and became the Menominee Range's largest iron-ore producer. Because part of the mine ran beneath a cedar swamp, keeping it dry took the Cornish Pump, a 725-ton, 54-foot machine that remains the largest standing steam-driven pumping engine built in the United States. It is now the centerpiece of a museum on Kent Street. As Dickinson County's seat, Iron Mountain anchors this corner of the Upper Peninsula near the Wisconsin line.

Where is the house?

Pick the county, city or township, and school district. We use the official 2025 tax rates published by Michigan Treasury.

Not sure of the school district? Check the property listing. It is usually under "Schools."

Need to double-check the exact parcel? Use the official state estimator at treas-secure.state.mi.us/ptestimator or call the local treasurer. Rates can change across city, township, village, and school district lines, so the exact parcel matters.

Why a buyer's property-tax bill can change after a sale

In Michigan, property tax isn't figured on what you paid — it's figured on the home's Taxable Value, with the local millage rates applied to that number. While one owner keeps the home, Proposal A caps how fast that Taxable Value can climb. When the home sells, the cap usually comes off — this is called uncapping — and the Taxable Value resets toward the State Equalized Value, or SEV, which tends to run about half of a home's market value.

That reset is the part that catches buyers: a longtime owner may have been paying on an old, capped number, so the year after you buy, yours can jump to the new one — and your first full-year bill can land well above what the seller was paying. In Iron Mountain, your rate can vary by parcel. The school district tied to the property matters, and 2 school districts cover Iron Mountain. For a primary home with PRE, Michigan's main-home exemption, rates currently run about 41.1 to 44.2 mills. Without PRE, non-homestead rates run about 59.1 to 62 mills. The calculator above turns those local rates into your actual number.

If this will be your main home, make sure that PRE is filed with the local assessor — it can lift up to 18 school-operating mills off the bill. Rentals, vacation homes, and second homes stay on the higher non-homestead rate.

The tax reset is the big one, but it isn't the whole checklist. It's also worth checking whether the address sits in a floodplain, and whether you'll owe a city income tax where you live or work. The buying-a-home guide walks through the rest.

Stories & local context

Get to know Iron Mountain

Ski jumping is the city's winter signature. Construction of the Pine Mountain jump began in 1937, and the first competition followed in 1939. The Kiwanis Ski Club still hosts FIS Continental Cup meets here, and FIS reported Clemens Aigner's 144-meter jump as a new hill record in 2020. Outside event closures, Dickinson County Tourism says Kramer Drive leads to the top of the platform and the U.P. Veterans Memorial sits at the base.

On the practical side, Iron Mountain does not levy a city income tax, so residents aren't taxed twice on their wages. As with the rest of Michigan, property taxes come in two bills a year, one in summer and one in winter. The notes below fill in the history and the tax details.
