What factors determine the breadth of an inspection's scope?

• A. The taxpayer's preference and convenience.
• B. The inspector's workload alone.
• C. Risk level, materiality, complexity, past non-compliance, and resource constraints.
• D. The color of the building where records are kept.

Answer: (C)

The breadth of an inspection’s scope is determined by a risk-based approach that weighs several objective factors. Risk level assesses how likely misstatements or noncompliance are and how big their potential impact could be. Materiality sets the threshold for what errors or issues would actually matter in the financial statements or compliance outcomes. Complexity reflects how intricate the taxpayer’s systems, transactions, or controls are and therefore how much effort is needed to test them adequately. Past non-compliance highlights areas with a history of issues, suggesting where problems may recur. Resource constraints acknowledge that inspectors have limited time, staff, and budget, so the scope must be feasible while still providing reasonable assurance.

Choices like relying on the taxpayer’s preference, the inspector’s workload alone, or irrelevant details (such as the building’s color) don’t align with how inspections are planned in practice, because scope is driven by objective risk and resource considerations rather than subjective convenience or meaningless factors.
