We investigate how personal income taxes affect the portfolio share of personal wealth that entrepreneurs invest in their own business. In a reformulation of the standard portfolio choice model that allows for underreporting of private business income to tax authorities, we show that a fall in...

It is well known that the implicit insurance provided by labor income taxes can reduce total saving. We show that this insurance can change the composition of saving as well because the reduction in labor-income risk may affect the amount of financial risk that an individual chooses to bear....

We study the welfare effect of tax-optimizing portfolio decisions in a life cycle model with unspanned labor income and realization-based capital gain taxation. For realistic parameterizations of our model, certainty equivalent welfare gains from fully tax-optimized portfolio decisions are less...

In order to calculate the burden of a comprehensive and progressive income tax falling on a certain income source, an apportionment scheme for the entire tax burden has to be chosen. This raises the question of how to deal with losses, which is relevant for Germany in view of the heavy losses...

This paper investigates the inter-temporal loss usage of tax units in Germany. Tax units that experience a loss in a year can offset that loss with positive income from adjacent year to receive a tax refund. Similar to companies, tax units can employ losses as carry-back in the year before the...

Tax preparation firms advertise their services as a way to save taxes. To investigate this subject, we use a panel of German income tax accounting data, consisting of employees and other taxpayers with non-business income, to explore the relationship between expenses for tax preparation and tax...

This paper extends prior stock option literature by examining whether individual and corporate tax incentives are associated with the decision to hold shares acquired through option exercises. Aboody, Hughes, Liu, and Su (2008) refute the previously-held assumption that individuals immediately...

The Child Tax Credit (CTC) is a major earnings subsidy in the US tax and transfer system, but its effects have received little research attention compared to the Earned Income Tax Credit. I identify the effects of the CTC on extensive margin labor supply using a difference-in discontinuities...

Prior research finds that firms pay special dividends before a dividend tax increase. We examine the real effects of this decision, finding that firms incur costs to pay these tax-motivated special dividends. Specifically, firms reduce investment and repurchases to pay these dividends. Further,...

In the tax policy debate, differentiation of value-added taxes is often justified by distributional concerns. Our quantitative analysis for Germany indicates that such concerns are misplaced. We find that the abolition of VAT differentiation has only negligible redistributive effects. Instead,...
