This study examines the extent to which taxpayers agree with aggressive tax
advice under a variety of conditions. It extends prior taxpayer aggressive
ness research by applying prospect theory and the theory of regulation. The
study reports the results of an experiment that uses a nationwide, random
sample of US taxpayers as subjects. The subjects read a scenario that invol
ves an ambiguous tax situation in which their professional tax preparer adv
ises an aggressive position. The subjects then state the degree to which th
ey agree with the aggressive advice. The experiment manipulates prepayment
position (refund vs. balance-due) and preparer type (certified public accou
ntant [CPA] vs. non-CPA) between subjects. The results, after controlling f
or economic sanctions and risk propensity, show that taxpayers are more lik
ely to agree with aggressive advice when they are in a balance-due prepayme
nt position and when they use CPAs as preparers. The study has implications
for tax policy makers and enforcement agencies. (C) 2001 Elsevier Science
