The social security payroll tax has become the largest tax paid by the majority of American households. Although, the statutory marginal social security tax rate is the same for all those with wage and salary income up to the maximum level, the complex rules linking social security taxes and...

This paper uses a panel of individual tax returns and the `bracket creep' as source of tax rate variation to construct instrumental variables estimates of the sensitivity of income to changes in tax rates. From 1979 to 1981, the US income tax schedule was fixed in nominal terms while inflation...

Since Feldstein (1999), the most widely used method of calculating the excess burden of income taxation is to estimate the effect of tax rates on reported taxable income. This paper reevaluates the taxable income elasticity as a measure of excess burden when individuals can evade or avoid taxes....

This paper generalizes the standard model of how taxes affect the labor-leisure choice by allowing individuals to change both their labor supply and avoidance effort in response to tax changes. Doing so reveals that both the income and substitution effect of taxes depend on both preferences and...

This paper compares marginal and average tax rates on working and saving under our current federal tax system with those that would arise under a federal retail sales tax, specifically the FairTax. The FairTax would replace the personal income, corporate income, payroll, and estate and gift...

This paper calculates monthly time series for the overall safety net's statutory marginal labor income tax rate as a function of skill and marital status. Marginal tax rates increased significantly for all groups between 2007 and 2009, and dramatically so for unmarried household heads. The...

Building on Gokhale, Kotlikoff, and Sluchynsky's (2002) study of Americans' incentives to work full or part time, this paper uses ESPlanner, a life-cycle financial planning program, in conjunction with detailed modeling of transfer programs to determine a) total marginal net tax rates on current...

This paper investigates whether taxpayers bunch at the kink points of the US income tax schedule (i.e. where marginal rates jump) using tax returns data. Clear evidence of bunching is found only at the first kink point (where marginal rates jump from 0 to 15%). Evidence for other kink points is...

The Affordable Care Act includes four significant, permanent, implicit unemployment assistance programs, plus various implicit subsidies for underemployment, and expanded Medicaid eligibility for adults. Every sector of the economy, and about half of nonelderly adults, is directly affected by at...
