Expert Opinions and Taxpayer Compliance: A Strategic Analysis

Abstract

In this paper we examine the incentives for taxpayers to claim risky deductions and to solicit expert opinions to support their positions, and for the tax agency to distinguish among individuals who do and do not solicit expert opinions for the purposes of auditing. We also consider the implications of an ex ante constraint on the tax agency which requires it to treat all taxpayers who take the deduction alike in terms of audit rates, whether or not they solicit an expert opinion. Finally, we examine the effects of regulations which limit the degree of riskiness for which a supporting opinion can be justified as well as the effects of changes in various penalty rates.
