A typical consumer spends exactly zero hours a day thinking about corporate tax compliance. Jeff Hoopes, a Tax Maven who devotes approximately 100% of his time to thinking about tax as the research director of the UNC Tax Center, explains why that disconnect matters. In this Episode, he explains the power and the limits of sophisticated enforcement tools such FIN 48 and the Schedule UTP and the humble credit card. He explores whether firms that donated to a particular political party respond differently to tax breaks such as those delivered by the 2017 tax law changes. Hoopes also shows why data from corporate tax returns challenge the conventional wisdom that private companies engage in more aggressive tax planning. His Pencil Question comes from an article by Edward J. Mccaffery in the Wisconsin Law Review.
