Michigan Property Value Estimator

Michigan assesses at 50% of true cash value and taxes taxable value. See how the two figures relate, when a transfer of ownership uncaps the taxable value, and estimate the tax that follows.

This is an estimate, not an appraisal. The tool does not value your property; it works through Michigan’s value chain from a figure you supply. It is not an official assessment, tax bill, or professional valuation.

How the Michigan estimate is calculated

The estimator applies Michigan’s verified value chain to the value you enter: the figures that convert a market value into the taxable value the rates apply to, using the state’s own assessment ratio, exemption amounts and cap mechanics. The state does not supply rates — rates are local — so the optional tax estimate uses the rate from your own bill. Every rule number is cited below and was verified from the official source listed.

Limitations

• This is not an appraisal: the true cash value you enter is assumed, not estimated by the tool.
• Without a transfer of ownership the capped value cannot be computed here — it needs the prior year's taxable value and the year's inflation rate multiplier, which this site does not publish. Your Notice of Assessment states the taxable value directly.
• Additions and losses enter the capped-value formula and are not modeled.
• Principal residence exemption (PRE) millage differences are not modeled.

Frequently asked questions

How does Michigan calculate property taxes?

Assessed value is 50% of true cash value, equalized to the state equalized value (SEV). The millage applies to taxable value — the lesser of the SEV or the capped value — unless a transfer of ownership uncapped it, in which case taxable value is the SEV for the year after the transfer.

Why is my taxable value lower than half the market value?

Proposal A. Since 1994 the capped-value formula has limited how fast taxable value can rise — at most the change in inflation or 5%, whichever is less. Long-held properties accumulate a large gap between taxable value and SEV.

I just bought the house. What happens to the taxable value?

It uncaps. In the calendar year after the transfer, taxable value becomes the state equalized value — often far higher than the seller's capped figure. The cap resumes the following year. This is the calculator's transfer checkbox.

Is this an appraisal?

No. Official values come from your city or township assessor, appeals run through the March Board of Review, and the Michigan Tax Tribunal is the state-level route.
