Michigan law requires assessors to send notices to taxpayers whose taxable or assessed values have increased. The City of Alma send notices to taxpayers, whose values have increased, stayed the same or decreased. It is a Notice of Assessment, Taxable Value, and Property Classifications. It is not a tax bill. You do not have to respond to this notice if you agree with the proposed values and classifications. However, we strongly urge you to contact us immediately upon receiving your notice if you disagree with the values or have questions. Michigan law and City Charter limits the appeal time period to the third Tuesday following the first Monday in March each year.
