Internal Control vs External Manipulation: A Model of Corporate Income Tax Evasion

Abstract:     
The purpose of this paper is to offer a formal model of corporate income tax evasion. While individual tax evasion is essentially a portfolio selection problem, corporate income tax evasion is much more complicated. When the owner of a firm decides to evade taxes, not only does it risk being detected by the tax authorities but, more importantly, the optimal compensation scheme offered to the employees will be altered. Specifically, due to the illegal nature of tax evasion, the contract offered to the manager is necessarily incomplete. This creates a distortion in the manager's effort, and reduces the efficiency of the contract. Tax evasion thus increases the profit retained by the firm not only at the expense of the risk of being detected, but also in the efficiency loss of internal control.
