Incentive effects and the income tax treatment of employer-provided workplace benefits

Employers often provide their employees with different kinds of benefits in the workplace to create comfortable working conditions. In order to avoid distortions of the wage-benefit ratio in employee compensation, economic theory suggests that fringe benefits should be subject to income taxation at a value placed on them by employees. This article shows that this approach does not apply to workplace benefits. Since the goal of these benefits is to reduce the employees’ disutility from work, treating them simply as wage substitutes disregards their incentive effects. Therefore, the rules for taxing workplace benefits are derived from an agency model. It is shown that in contrast to the standard economic approach, cost can be a more efficient tax base than willingness to pay, even though this results in higher tax payments. Moreover, with non-distortionary tax rates it is always better to tax the employer rather than the employee.
