Bush was faced with a rare opportunity: a projected federal budget surplus. Bush quickly decided that the government should use this surplus to lower the federal tax burden. Tax rates lowered across the board, with rates falling from 15%–39.6% to 10%–35%. Estate tax was phased out. These cuts were further extended by the Jobs and Growth Tax Relief Reconciliation Act of 2003 which lowered the maximum tax rate on stock dividend and capital gains income, and increased deductions from the corporate tax.

An ongoing debate throughout the Obama presidency was whether and how to end the Bush tax cuts. Obama stated tax cuts for the wealthiest Americans are the tax cuts that are least likely to promote growth. Republicans argued that higher taxes in the midst of a recession would hurt the economy further by punishing job-creating small businesses that pay taxes under the individual income tax code.

When they expired (again) in 2012, a compromise was reached through the American Taxpayer Relief Act of 2012. Introduction

Tax deductions and tax credits began to be phased out for those making over $250,000 or $300,000, for individuals and couples, respectively. The estate tax increased from 35% to 40%. These debates highlight the important role that taxes play in both the political arena and government policy making in the United States. Introduction

Barr found that 155 high-income households had earned over $200,000 in 1966 but paid zero income taxes. The alternative minimum tax was meant to make sure high-earners still paid taxes. o Alternative Minimum Tax: A tax schedule applied to taxpayers with a high ratio of deductions and exemptions to total income. Requires that income (before subtracting exemptions and deductions) be taxed at 26% or more. APPLICATION: Fixing the AMT

The AMT adds dramatic complexity to the tax code, so repealing it has broad support… …but it is an important source of revenue; repeal would cost at least $1.3 trillion between 2011 and 2022. APPLICATION: Fixing the AMT

The fix was more affordable due to partially ended tax cuts from prior years, costing $350 billion over next decade. Under the revision, 3.9% of taxpayers versus 41.8% would be hit by the AMT. APPLICATION: Fixing the AMT

Two key features of any tax system: o Marginal tax rate: The percentage that is paid in taxes of the next dollar earned. o Average tax rate: The percentage of gross income that is paid in taxes. In the United States, the marginal tax rate rises with income, from 10% to 35%. Measuring the Fairness of Tax Systems

Horizontal equity: The principle that similar individuals who make different economic choices should be treated similarly by the tax system. Vertical and Horizontal Equity

Progressive: Tax systems in which effective average tax rates rise with income. Proportional: Tax systems in which effective average tax rates do not change with income, so that all taxpayers pay the same proportion of their income in taxes. Regressive: Tax systems in which effective average tax rates fall with income. Measuring Vertical Equity

Consider the income tax cuts proposed by President Bush and signed into law by Congress in 2003: o 44% of the tax cuts went to the top 1% of payers… o …but top taxpayers pay 38% of income taxes, and o …they pay only 30% of all taxes, due to the other tax revenues being collected from proportional taxes, and o …34 million families with children would receive an average tax cut of $1,549 each.

Haig-Simons comprehensive income definition: Defines taxable resources as the change in an individual’s power to consume during the year. Potential annual consumption: Total consumption during the year, plus any increases in wealth. Difficulties: o Defining power to consume/ability to pay o Nonconsumption expenditures 18.4 Defining the Income Tax Base: The Haig-Simons Comprehensive Income Definition

One reason for deviation is to account for expenses not associated with desired consumption. o Deductions for property and casualty losses o Deduction for medical expenditures o Deduction for state and local tax payments Defining the Income Tax Base: Deviations due to Ability-to-Pay Considerations

A man tried to deduct $30,000 in expenses on illegal drugs. o Allowed to claim deductions, he was sentenced for criminal charges. Many OECD countries have traditionally allowed/ treated foreign bribes as business expenses. APPLICATION: What Are Appropriate Business Deductions?

Charitable giving likely underprovided. o People may give to homeless shelters because of the tax break, but these would be underfunded otherwise. Externality/Public Goods Rationales for Deviating from Haig-Simons: Charitable Giving
33
33 of 53 Public Finance and Public Policy Jonathan Gruber Fifth Edition Copyright © 2016 Worth Publishers C H A P T E R 1 8 ■ T A X A T I O N : H O W I T W O R K S A N D W H A T I T M E A N S 18.5 Alternatively, the government could provide homeless shelters. Why not do so? If the government subsidizes homeless shelters, the amount of private charitable giving to those shelters would most likely fall. When the government tax subsidizes charitable giving, it may “crowd in,” or increase, private contributions. Spending Crowd-Out Versus Tax Subsidy Crowd-In

Marginal impacts: Changes in behavior the government hopes to encourage through a given tax incentive. Inframarginal impacts: Tax breaks the government gives to those whose behavior is not changed by new tax policy. Marginal Versus Inframarginal Effects of Tax Subsidies
35

If this holds, then giving more of a tax break (and reducing government spending) increases charitable giving. Several studies have concluded that for each 1% fall in the price of charitable giving, the amount of giving rises by 1%. Effects of Tax Subsidies Versus Direct Spending

Tax subsidies to private individuals respects the preferences of citizens. But the private sector may not have the appropriate mechanisms in place to ensure efficient distribution of charitable spending. Most individuals do little research before donating. This approach has the potential to lead to gifts that don’t provide much benefit to the intended target. Consumer Sovereignty Versus Imperfect Information

Rent is not tax deductible. Home ownership may provide externalities through responsible citizenship. Housing

Subsidy increased home ownership by 7−11%. But no external benefits: o Treatment and control groups equally involved in civic activities. o Treatment group spent more on home improvements, but only on the inside, providing no external benefit.

Tax deductions: Amounts by which taxpayers are allowed to reduce their taxable income through spending on items such as charitable donations or home mortgage interest. Tax credits allow taxpayers to reduce the amount of tax they owe to the government by a certain amount (e.g., the amount they spend on child care). How should the government decide which to use? Tax Deductions Versus Tax Credits
41
41 of 53 Public Finance and Public Policy Jonathan Gruber Fifth Edition Copyright © 2016 Worth Publishers C H A P T E R 1 8 ■ T A X A T I O N : H O W I T W O R K S A N D W H A T I T M E A N S 18.5 Consider replacing charitable giving deduction with a tax credit for up to $1,000. For people giving less than $1,000, the credit provides a much stronger incentive to increase giving. Once a person gives more than $1,000, there is no more benefit from the tax credit. Policy preference depends on: o The nature of the demand for the subsidized good. o How important it is to achieve some minimal level of the behavior. Efficiency Considerations

The value of a deduction rises with one’s tax rate, making deductions regressive. Credits, on the other hand, are available equally to all incomes so that they are progressive. Equity Considerations

Refundable: Describes tax credits that are available to individuals even if they pay few or no taxes. Many conservatives object to the notion that those who owe little or no income taxes get a refund. Supporters note that, while low-income families pay little income tax, they do pay a large share of their income on other taxes. APPLICATION: The Refundability Debate

In 2001 tax cuts, families received a refund for at most 10% of their income above $10,500. 2003 tax cuts expanded the credit, and the President said families would get a $400 check in the mail, but last-minute changes prevented low-income families from receiving the benefit of the increase. In 2009, the earnings threshold was lowered so an additional 3 million children qualified for the credit, thus increasing the benefit to 10 million children. APPLICATION: The Refundability Debate

Tax expenditures are enormous, predicted to be $1.3 trillion in 2016. Bottom Line: Tax Expenditures
