Property Taxes in Ludington: Michigan's Proposal A, Explained

Proposal A: Why Michigan Property Tax Doesn't Track Market Value Directly

Michigan voters approved Proposal A on March 15, 1994, specifically to limit how fast property tax bills could grow for an existing owner, even as underlying market values rose. The mechanic: every property has both a State Equalized Value (SEV, set annually by the local assessor and intended to represent roughly half of the property's true cash/market value) and a separate Taxable Value, which is the number your actual tax bill gets calculated against. Under Proposal A, Taxable Value can only rise each year by the lesser of the rate of inflation (measured by the Consumer Price Index) or 5% -- regardless of how much the property's real SEV or market value jumps in that same year. For an owner who holds a property for many years in a market with real appreciation, this creates a genuine, growing gap between a property's Taxable Value (what's actually taxed) and its SEV/market value (what it could sell for) -- exactly the protection Proposal A was designed to provide for long-term Michigan residents.

This is a fundamentally different system than a straightforward market-value assessment model, and it matters enormously for anyone comparing a listed 'current tax bill' to what they'll actually pay after buying.

Uncapping: The Mechanic That Changes Everything the Year After a Sale

Here's the part that catches out-of-state buyers most often: when a property is sold, that Proposal A cap disappears. The Taxable Value 'uncaps' and resets to match the property's current SEV as of January 1 of the year following the transfer -- not gradually, in one step. Practically, that means a property that has been under-assessed relative to market value for years, because a longtime owner benefited from the cap, can see its actual tax bill jump meaningfully in its first full year under new ownership, even with no change in the local millage rate at all. A prior owner's tax bill, or a tax figure quoted on an old listing sheet, tells you almost nothing about what a new buyer will actually owe -- it reflects that seller's capped Taxable Value, not the SEV-based Taxable Value a buyer inherits after the uncapping.

There are real, specific exceptions to uncapping worth knowing: transfers between spouses (including those resulting from a death) do not trigger uncapping, and a transfer from a deceased owner to a qualifying relative heir (a child, grandchild, sibling, or parent, or the spouse of any of those) can also preserve the capped Taxable Value if the property's residential use continues. Those exceptions matter for estate planning and family transfers, but they don't apply to an ordinary arm's-length purchase -- which is the scenario most buyers researching this page are actually in.

The Principal Residence Exemption: A Real, Meaningful Reduction -- If You Qualify

Michigan's Principal Residence Exemption (PRE) exempts a property from up to 18 mills of local school operating tax, and multiple sources describe this as reducing most Michigan homeowners' total property tax bill by roughly 25% to 35% compared to the same property without the exemption. The City of Ludington's own 2025 millage schedule shows exactly this gap in practice: 40.6725 total mills for a primary residence claiming the PRE, versus 58.6725 total mills for a non-primary property that doesn't qualify -- an 18-mill difference consistent with the PRE's stated scope.

To claim the PRE, an owner files an affidavit with the local tax-collecting unit (the City of Ludington, in this case) by June 1 for that year's summer tax levy, or by November 1 for that year's winter levy. Once filed, the exemption stays in effect for all future levies until the owner rescinds it or becomes ineligible -- meaning a second-home or vacation-property buyer who does not make the property their principal residence should plan around the 58.6725-mill non-primary rate, not the lower primary-residence figure, since the PRE specifically requires the property be the owner's actual principal residence, not simply a Michigan property they own.

The City's 2025 Millage Rate, and What a Real Bill Looks Like

Per the City of Ludington's own published 2025 rate schedule, total annual millage runs 40.6725 mills for a primary residence with the PRE applied, and 58.6725 mills for a non-primary property. A mill is one-tenth of one cent per dollar of Taxable Value -- so a property with a Taxable Value of $150,000 would owe roughly $6,101 a year at the primary-residence rate ($150,000 ÷ 1,000 × 40.6725) or roughly $8,801 a year at the non-primary rate ($150,000 ÷ 1,000 × 58.6725). Those are this page's own illustrative calculations on the confirmed millage figures, not a substitute for an actual bill -- the real number depends entirely on the specific property's current Taxable Value, which (per the uncapping mechanic above) may differ substantially from what a prior owner's bill implied. The 2025 rate schedule also references a state inflation-rate multiplier of 1.031 applied to that year's cap calculation, consistent with the CPI-based annual cap Proposal A sets.

What a Buyer Should Actually Do Before Closing

Because of the uncapping mechanic, the single most useful thing a Ludington buyer can do before making an offer is request the property's current SEV (not just its current Taxable Value or the seller's current tax bill) directly from the City of Ludington Assessor's office or the Mason County Equalization Department, then estimate the post-sale tax bill using that SEV figure and the applicable millage rate -- rather than assuming the number on a listing sheet or a prior year's tax bill will carry forward. This is a materially different due-diligence step than what a buyer moving from a straightforward market-value-assessment state would think to ask for.

This page does not state Michigan's current homestead, elderly, disabled, or other property tax relief/credit program eligibility thresholds beyond the PRE described above -- those programs exist at the state level, but current income and eligibility thresholds change and weren't independently re-verified for this build. Ask the Mason County Treasurer's Office or a Michigan tax professional directly about any relief program you might qualify for.
