This book is an overview of issues associated with the marriage penalty. The first section explains how the marriage penalty (and the marriage bonus) arises and why it is not possible to achieve simultaneously the goals of marriage neutrality and horizontal equity across families in a progressive tax system. The second section discusses the size of the marriage penalty, the bonus and importantly, the notion that the marriage penalty is not a precisely defined measure. The next section outlines the issues of equity, efficiency and simplicity that are part of the frame work for evaluating policy and the final section discusses various legislative proposals in light of these objectives. The book also estimates the effects of current tax policies on families of different types and sizes and analyses proposals to address the marriage penalty and the child tax credit. It contains a history of the development of tax provisions affecting the family.
The question of how to tax married couples has remained controversial since the adoption of the federal income tax over a century ago. The appropriate answer to this question depends in part on how sensitive couples are to taxes when deciding to marry. Yet we know surprisingly little about how taxes shape couples' marriage choices. This Article begins to fill that gap using a natural experiment generated by the halting shift in how the income tax treated married couples in the mid-Twentieth Century. The system moved from taxing married couples as two individuals--in which case marriage largely did not affect taxes--to taxing married couples on their joint income. At the time of this shift, joint taxation lowered couples' taxes upon marriage. The change to joint taxation, however, came later to some states, creating a natural experiment to study its impact on marriage rates. This Article shows that annual marriage rates increased by 9% in the relevant states after the introduction of joint taxation made marriage tax-advantaged, with affected men marrying 3 to 5 months sooner on average. This suggests that at any given time during this period there were tens or hundreds of thousands of married couples in the United States who would not have been married if not for the tax incentives. Couples appear to have been unexpectedly responsive to the tax changes given that unmarried cohabitation was not acceptable under the social mores of the day. If anything, Americans today are likely more sensitive to taxes when deciding whether and when to marry, suggesting that joint taxation continues to affect marriage decisions today. This in turn strengthens the case for returning to individual taxation of marriage if the goal is to avoid inefficiently distorting people's marriage decisions. By contrast, if the government wishes to encourage marriage, the results imply that using the tax code may be effective under some circumstances, but further analysis suggests that joint taxation remains a poor choice for doing so.
Examines the ways in which federal tax law affects the income taxes that married couples pay & how demographic & labor market changes over the last two decades have altered those effects. It also discusses a variety of possible changes in the federal tax code that would reduce the higher tax liabilities that married couples often incur because they cannot file individual tax returns. Included in the appendixes are discussions on the tax treatment of married couples in other countries & under state income taxes. Charts & tables.
This article analyzes the effects of differential tax treatment of married and single individuals in the United States on marriage formation and composition, divorce, and labor supply. We develop a marriage-market model with search frictions and heterogeneous agents that is sufficiently rich to capture key elements of the problem under consideration. We then calibrate the model and use it to evaluate the quantitative effects of several tax reforms aimed at making the tax law neutral with respect to marital status. We find that these reforms (i) systematically increase the labor supply of married females, with changes ranging from 0.3 to 10.1 percent; (ii) have substantial effects on the correlation of spouses' incomes, which changes from 0.2 to values between 0.185 and 0.334; (iii) can lead to either an increase or decrease in the fraction of people married, with changes that range from 0.6 to 2.4 percent.
