How Does the Deferral of a Distortive Tax Affect Overproduction and Asset Allocation?

Deferred income taxation is widely used to encourage investment or saving. However, most income tax bases are more or less distortive (non-neutral). Using lab experiments, we find that the deferral of a distortive income taxation can result in substantial overproduction and less willingness to take risks. Subjects underweight the deferred tax burden and neglect the tax distortion because they act myopically and tend to make choices in isolation rather than simultaneously (choice bracketing). Despite opportunities to learn, the overproduction remains substantial. Additional analyses confirm that the observed misperception of deferred taxes is not caused by low tax salience or low effort, as providing additional accounting information on deferred taxes and introducing accountability reports do not change overproduction behavior. Only if we change the timing of the taxation from deferred to an economically equivalent immediate distortive tax system do overproduction and the effect on asset allocation almost disappear.
