Abstract:
The recent German discussion has witnessed increasing interest in the Dual Income Tax. The analysis of its merits, as opposed to those of a comprehensive income tax, is usually conducted with the main argument of the increasing mobility of financial capital in mind. This article pursues an alternative route of reasoning, arguing that the composition of the tax base of labor income entails a differentiation of the tax rates on capital and labor income. The time effect inherent in this dualism causes allocation distortions of unknown magnitude. It is modeled employing effective tax rates. The extent of the divergence is determined empirically, using German cross-sectional data from the 2004 wave of the Socio-Economic Panel. The uneven distribution of this advantage across differently educated brackets of society is uncovered. The paper concludes with proposals to remedy the situation and a tentative endorsement of the Dual Income Tax.

Abstract:
The contribution Bach, Corneo, and Steiner (2008) has argued that "the rich" do not pay taxes adequately in relation to their income, finding, for instance, an effective tax rate of only 38.1% for the 0.001% fractile of German income taxpayers in 2001. This result contrasts sharply with the legislated top marginal income tax rate of 48.5%. We subject the results contained in Bach, Corneo, and Steiner (2008) to a rigorous analysis: We find major flaws and inconsistencies with regard to methodology, i.e. the omission of corporate taxes and intertemporal aspects of taxation. Restating basic rules for the measurement of effective tax rates, we provide values for what we term the "comprehensive nominal tax rate" (CNTR) and show that the headline result in Bach, Corneo, and Steiner (2008) of 38.1% is underestimated by over 12 percentage points. As an important distributional result, the CNTR increases with increasing taxable income.
