This paper applies a numerical optimization technique using microunit tax data to the problem of choosing the parameters of a flat-rate tax system, should one be desired. Our approach is to first formulate explicit objectives that a flat-rate tax might reasonably be designed to meet, such as...

This paper examines the impact of the Alternative Minimum Tax on the weighted average marginal tax rates that apply to various components of taxable income. It also considers the impact of several AMT reform proposals on the number of AMT taxpayers, the total revenue collected from the AMT, and...

Relative to traditional piecewise linear income taxation schemes, it is possible to increase government revenues by offering to consumers a menu of linear income tax schedules. In the resulting Pareto-superior equilibrium, consumers sort themselves out according to their (unobservable)...

We investigate the optimal rate structure of an income tax system that is constrained to have only two brackets, plus a demogrant. We find that, in a two-class economy, Pareto efficient tax schedules feature at least one marginal tax rate equal to zero, and that the marginal tax rate may be...

The optimal income tax problem, since it requires self-selection constraints which define nonconvex feasible sets, is one of the many problems in economics for which randomization in the solution may be desirable. For a two-class economy. we characterize the optimal random tax schedules and we...

In this short paper we show that progressive income taxes distort hiring and wages when firms have labor market power. From a firm's perspective, raising pre-tax wages increases employment by less when taxes are progressive as less of the pre-tax wage is paid to workers. Understanding this when...

This paper investigates the effect of entrepreneurs' personal income tax situations on their use of labor. We analyze the income tax returns of a large number of sole proprietors before and after the Tax Reform Act of 1986 and determine how the substantial reductions in marginal tax rates...

The share of pre-tax income flowing to the top of the UK income distribution increased continually and substantially in the three decades leading up to the financial crisis, but has changed little since 2013. Using microdata sampled from UK tax records, we describe the nature of top incomes in...

Over three-quarters of US taxpayers receive income tax refunds, indicating tax prepayments above the level of tax liability. This amounts to a zero interest loan to the government. Previous studies have suggested two main explanations for this behavior: precautionary behavior in light of tax...

Only one-fifth of respondents to a rider on the University of Michigan Survey Research Center's Monthly Survey said that the 2008 tax rebates would lead them to mostly increase spending. Almost half said the rebate would mostly lead them to pay off debt, while about a third saying it would lead...
