true cash value
• Proposal A of 1994: Constitutional amendment capping taxable value increases and changing
school funding

250 Scenario-Based MCQs with Rationales
Questions are organized by module and formatted as on the actual MCAO exam. All questions exceed 15
words and include rationales based on Michigan General Property Tax Act, STC guidelines, and Proposal
A.
Module 1: Michigan Assessing Law & General Principles (Questions 1-35)
, Page 3 of 159
1. A property owner asks why their assessed value is only half of what their neighbor sold their house for
last month. What is the correct explanation of Michigan's constitutional assessment requirement?
A) The assessor made an error and must raise the assessment immediately
B) All taxable property must be assessed at 50% of its true cash value under Article IX, Section 3
C) The property owner can choose to be assessed at either 50% or 100% of market value
D) Only commercial property follows the 50% rule; residential follows 100%
Rationale: The Michigan Constitution (Article IX, Section 3) requires all taxable property to be assessed
at 50% of true cash value. The neighbor's sale price represents 100% of market value, so the assessed
value should be approximately half of that sale price.
2. An assessor is reviewing the primary law governing property assessment in Michigan. Which act
serves as the foundational legal authority for assessment practices?
A) Public Act 206 of 1893, as amended (General Property Tax Act)
B) Public Act 228 of 2002 (Uniform Assessment Act)
C) Public Act 203 of 1976 (Tax Tribunal Act)
D) Public Act 94 of 1994 (Proposal A Implementation Act)
, Page 4 of 159
Rationale: The General Property Tax Act (Public Act 206 of 1893, as amended) is the primary law
governing property assessment in Michigan. All assessment practices must comply with this
foundational statute.
3. During a taxpayer consultation, the owner asks what "true cash value" means for assessment
purposes. Which definition best explains this term as used in Michigan property tax law?
A) The original purchase price adjusted for inflation
B) The replacement cost of all buildings on the property
C) The usual selling price on the open market between a willing buyer and willing seller
D) The assessed value multiplied by the local equalization factor
Rationale: True cash value is synonymous with fair market value – the price a willing buyer and willing
seller would agree upon in an open and competitive market, neither being under compulsion to buy or
sell.
4. A newly elected township official asks why assessments cannot be set at 100% of market value like in
some other states. What is the Michigan constitutional requirement for assessment percentage?
A) 25% of true cash value for all property types
