Taxable Value vs. State Equalized Value
Michigan homes have two key values. State Equalized Value (SEV) is 50% of the assessor's estimate of the home's true cash (market) value. Taxable Value is what your property taxes are actually calculated on.
Proposal A caps increases while an owner keeps the home
Under Proposal A, approved by Michigan voters in 1994, taxable value can rise each year by no more than 5% or the rate of inflation, whichever is less, as long as ownership doesn't change. After years of capped increases, a long-time owner's taxable value can sit far below SEV.
The year after a sale, taxable value “uncaps”
A transfer of ownership uncaps the taxable value in the calendar year following the sale, and it resets to the SEV (50% of true cash value). That's why the seller's current tax bill can understate what you'll pay. In our hypothetical example, the seller's bill is $3,100/yr, while the buyer's estimate after uncapping is about $5,145/yr.
