THE TAX DEBATE OF THE 1990s AND BEYOND McGrawHill/Irwin © 2002 The McGrawHill Companies, Inc., All Rights Reserved Where Personal Income Taxes Fit • In 2000 the federal government collected $1,956 billion in taxes • $952 billion of that was collected from the personal income tax • The remainder was collected in payroll taxes (for Social Security and Medicare), corporate income taxes, tariffs and other taxes McGrawHill/Irwin © 2002 The McGrawHill Companies, Inc., All Rights Reserved How Income Taxes Work • When people get a new job they fill out a W-4 which is used to calculate withholding (an estimate as to how much tax you are going to owe on the earned income) This money is taken out of a paycheck and sent, by the employer to the federal government • The estimate is reconciled with actual income taxes owed with the Income Tax Return filed by April 15th of the following year McGrawHill/Irwin © 2002 The McGrawHill Companies, Inc., All Rights Reserved The Vocabulary of Income Taxes • Adjusted Gross Income (AGI) – total net income from all sources • Exemptions – an amount by which AGI is reduced that is determined by the size of the family • Deductions – amounts by which AGI is reduced; the greater of either the standard deduction (the minimum level of deduction)or itemized deductions (deductions for particular expenses on which the government does not want taxes paid) • Taxable Income AGI-Exemptions-Deductions McGrawưHill/Irwin â2002TheMcGrawưHillCompanies,Inc.,AllRightsReserved More Vocabulary Filing Status – the type of household for tax purposes (Single, Married Filing Jointly, Married Filing Separately and Single Head of Household) • Marginal Tax Rate – the percentage of each dollar in that bracket that must be paid in tax • Tax Credits – The reductions off

Income Tax Credit +College Tuition Credit+ Child Care Credit+Dependent Child Credit = What You Owe McGrawHill/Irwin © 2002 The McGrawHill Companies, Inc., All Rights Reserved Issues in Income Taxation: Fairness • Horizontal Equity – equal people should be treated equally • Vertical Equity – people across the income scale are treated fairly with regard to ability to pay • Progressive Income Tax – with higher income you pay a higher rate of tax The marginal tax rate rises from 15% to 28% to 31% and higher as taxable income rises McGrawHill/Irwin © 2002 The McGrawHill Companies, Inc., All Rights Reserved Issues in Income Taxation: The Equity-Simplicity Tradeoff • Economists want a tax code to be neutral (a characteristic of a tax code that implies that it does not favor particular forms of income or expenditure) • For neutrality to happen taxes must often be complicated Consider capital gains (any profit you have from asset sales) as an example It order to tax capital gains in a neutral way to other income you have to make capital gains tax rules very complicated McGrawưHill/Irwin â2002TheMcGrawưHillCompanies,Inc.,AllRightsReserved Capital Gains To be neutral you should – not tax the gains that exist only because of inflation, – tax each year based on the paper increases or decreases in value (called on accrual) rather than when the asset is sold (called on realization) – tax the capital gains on assets of those who have died before they sold their assets • To be simple you should – tax all gains, – tax only on realization, – Forgive capital gains taxes on death (because locating the paperwork is difficult • What we – Tax all gains on realization while forgiving gains for those who have died – The tax rate is lower for capital gains than for ordinary income McGrawHill/Irwin © 2002 The McGrawHill Companies, Inc., All Rights Reserved Incentives in the Tax System • Whether the income tax discourages or encourages work or savings boils down to the income effect and the substitution effect of that tax policy – Income effect • The effect on work or saving just accounting for the tax money taken away – Substitution effect • The effect on work or saving just accounting for the change in the relative value of working or saving McGrawưHill/Irwin â2002TheMcGrawưHillCompanies,Inc.,AllRightsReserved Empirical Evidence on Incentives Work Most economists have found that there is nearly no impact of tax rates on number of hours worked Some estimate that it takes an 8% increase in the marginal tax rate to reduce work by 1% • Saving – There are differing estimates of the impact but most economists agree that an increase in taxes reduces savings slightly One estimate has a 2.5% decrease in the after-tax interest rate decreasing savings by 1% McGrawưHill/Irwin â2002TheMcGrawưHillCompanies,Inc.,AllRightsReserved Taxes for Social Engineering Tax Incentives exist to induce people to – Save for college – Send their children to college • It is uncertain whether these tax provisions cause people to go to college McGrawưHill/Irwin â2002TheMcGrawưHillCompanies,Inc.,AllRightsReserved Who Pays the Federal Income Taxes the bottom half of taxpayers pays only 5% of the income tax while the top half pays the remaining 95% • the top 10% of taxpayers accounts for 63% of federal income taxes paid • The top 5% of taxpayers accounts for more

cut – will go almost entirely to people in the top 50% of income earners and more than half will go the top 5% – will change the after-tax income distribution in favor of high-income taxpayers
