Every year in late February, homeowners across Oakland, Wayne, Macomb, and Washtenaw Counties open their mailboxes to find an official postcard or letter from their local city or township assessor. Written across the top in bold letters is a phrase that confuses almost everyone: "THIS IS NOT A TAX BILL."
Yet that single piece of paper—your annual Notice of Assessment, Taxable Valuation, and Property Classification—determines exactly how much money will be drained from your bank account on your summer and winter property tax bills.
Most Michigan homeowners glance at the sheet, get confused by the three different columns of numbers (True Cash Value, Assessed Value/SEV, and Taxable Value), and toss it in a drawer. By the time the actual tax bill arrives in July, the strict March deadline to protest your assessment has already passed!
Here is a plain-English guide to decoding your Michigan assessment notice—and how to tell in 60 seconds if you are being overtaxed.
The 3 Numbers on Your Michigan Assessment Notice Explained
1. True Cash Value (TCV) — What the Assessor Claims Your Home Is Worth
In Michigan property tax law, True Cash Value (TCV) is the government's term for Fair Market Value—what the local assessor believes your home would sell for in an open-market transaction.
- The Catch: Township assessors almost never step foot inside your home. Instead, they rely on "mass appraisal" computer models that adjust an entire neighborhood upward at once, ignoring whether your specific home has an older kitchen, a wet basement, a busy road backing, or less usable square footage than the house down the street.
2. State Equalized Value (SEV) / Assessed Value — The 50% Rule
Under Michigan's Constitution, your State Equalized Value (SEV) must equal exactly 50% of your home's True Cash Value.
- *Example:* If your city assessor in West Bloomfield, Troy, Birmingham, or Novi lists your SEV at $250,000, they are officially claiming that your home's True Cash Value (Fair Market Value) is $500,000 ($250,000 × 2).
- How to Spot an Over-Assessment: Look at your current SEV and double it. Could you realistically sell your home today, in its current condition, for that doubled amount? If the answer is no, your property is over-assessed!
3. Taxable Value (TV) — The Number Your Tax Bill Is Multiplied By
Your Taxable Value is the figure multiplied by your local millage rate to calculate your actual dollar tax bill. Under Michigan's Proposal A (passed in 1994), as long as you remain in your home and don't add major structural additions, your Taxable Value can only increase each year by the rate of inflation (up to a maximum cap of 5%)—and your Taxable Value can never be higher than your SEV.
Why Appealing an Inflated SEV Saves You Real Money
Some longtime homeowners notice that their SEV is $250,000 while their capped Taxable Value is $210,000, and assume appealing won't help them. However, there are two massive reasons to fight an inflated assessment:
- If You Recently Bought Your Home (Within the Last 1–3 Years): Because your Taxable Value "uncapped" to match the SEV in the year after you bought the home, your Taxable Value and SEV are virtually identical. Every $10,000 reduction in your SEV/Taxable Value immediately lowers your annual property tax bill—and re-establishes a lower Proposal A cap for every year you own the home!
- If Market Values Have Softened or Your Home Has Condition Issues: If a certified appraisal proves your True Cash Value is actually $380,000 (meaning a $190,000 SEV), your Taxable Value is forced down from $210,000 to $190,000 immediately.
