August 2016The Lifecycle of the 47%
with Don Fullerton: w22580
We assess the concentration and duration of zero tax liabilities and of transfer receipts, using data for households with ten to forty years of observations from the Panel Survey of Income Dynamics. We find that neither is strongly concentrated. Nearly 68% owe no federal tax in at least one year, approximately 78% receive some type of transfer in at least one year, and more than 58% receive transfers other than Social Security in at least one year. Of those who do not owe federal tax in any given year, 18% pay tax the following year, and 39% contribute within five years. Of those who receive transfers other than Social Security within a given year, nearly 44% stop receiving such transfers the next year, and more than 90% stop within ten years.
February 2007Deferred Tax Positions and Incentives for Corporate Behavior Around Corporate Tax Changes
with James Poterba, Jeri Seidman: w12923
A firm's deferred tax position can influence how it is affected by a transition from one tax regime to another. We compile disaggregated deferred tax position data for a sample of large U.S. firms between 1993 and 2004 to explore how these positions might affect firm behavior before and after a pre-announced change in the statutory corporate tax rate. Our results suggest that the heterogeneous deferred tax positions of large U.S. corporations create substantial variation in the short-run effect of tax rate changes on reported earnings. Recognizing these divergent incentives is important for understanding the political economy of corporate tax reform.
