3. Income Taxes The Federal Income Tax We start with the federal income tax because most state taxes are linked to it. We will discuss the broad issues in the design of the federal income tax. Then we will turn to state and local income taxes.
4. Income Taxes Federal Income Tax Design Comprehensive Income - Exclusions = Adjusted Gross Income - Exemptions - Deductions (Itemized or Standard) = Taxable Income × Tax Table = Gross Tax - Tax Credits = Net Tax
5. Income Taxes Exclusions & Exemptions Exclusions Interest income on municipal bonds Implicit rent on owner-occupied housing Exemptions Personal exemptions ($3,800) Exemptions for dependents Exemptions for age and some categories of disability
6. Income Taxes Deductions Itemized Deductions Mortgage interest on primary residence (and some secondary) Property taxes on primary residence (and some secondary) State income taxes (or state sales taxes—but not both!) Charitable contributions Excess medical expenses Standard Deduction Fixed amount (used by most taxpayers) $11,900 for joint return.

10. Income Taxes Marginal to Average Rates Translation from marginal to average rates is complicated. Marginal rate tables are highly misleading due to phase outs. All the other features of the tax code affect average rates. Deductions are particularly powerful at the highest income levels.

15. Income Taxes Tax Reform Act of 1986 (TRA) TRA was a remarkable bi-partisan reform that closed loopholes (favored by liberals) and lowered marginal rates (favored by conservatives). These two are linked—broadening the base makes lower rates possible. This reform also shifted the burden from individuals to corporations. Since TRA loopholes have been added at a rapid rate!
16. Income Taxes Link to State Income Taxes Most state income taxes either A. use federal taxable income and their own tax tables, or B. set their tax as a percentage of federal tax. The “A” states gained from base broadening in the 1986 TRA. The “B” states lost from the shift away from individual income taxes in TRA.
17. Income Taxes Progressivity in State Taxes The “A” States, the ones with federal taxable income, have less progressive rate structures than the federal tax. These taxes are even less progressive than they seem because of federal (or federal and state) deductibility of income taxes paid. Progressivity is limited by the ability of rich individuals to move to another state in response to a high state income taxes—but this effect is small.

19. Income Taxes Local Income Taxes A few cities (e.g. Baltimore, Detroit, New York) have income taxes of their own, usually linked to their state tax. Most local income taxes are limited to wages and salaries and take the form of either an earnings tax (with legal incidence on workers) a payroll tax (with legal incidence on firms)
20. Income Taxes Commuter Taxes A few cities (e.g. Newark, San Francisco, Cleveland, Philadelphia) collect taxes on the wages and salaries earned by non-residents within the city. Payroll taxesdo this automatically.
21. Income Taxes Commuter Taxes, 2 Commuter taxes only work if cities have access to them but suburbs do not. The first claim on taxable resources goes to the jurisdiction of residence. So if a city passes an income tax, the suburbs can pass one and claim all the taxes paid by their commuting residents—with no increase in the tax on those residents! This happened in Pittsburgh.
22. Income Taxes Commuter Taxes, 3 Commuter taxes have the advantage that they can help satisfy the benefit principle—people who benefit from the services in the city where they work help pay for these services. Commuter taxes have the disadvantage that they may encourage firms (not households) to leave a city, although the evidence on this effect is mixed.
23. Income Taxes Selected Issues in Federal Tax Policy The “Marriage Penalty” The EITC Tax Deductions for Homeownership
24. Income Taxes The Marriage Penalty The U.S. tax code has several tax schedules. The main two are: Tax rates for single people. Tax rates for married people filing joint returns, which have wider tax brackets (e.g. $0 to $15,000 for the first bracket instead of $0 to 10,000). The idea is not to penalize people for getting married. But neither the brackets nor the standard deduction are doubled for two people who get married.
25. Income Taxes The Marriage Penalty, 2 The result: Marriage penalties and marriage bonuses. A “marriage penalty” is defined as a situation in which a couple pays more income tax filing jointly than they would if they had remained single. A “marriage bonus” is defined as a situation in which a couple pays less tax filing jointly than they would if they had remained single. Marriage bonuses are more common.
26. Income Taxes The Marriage Penalty, 3 Couples most likely to face a marriage penalty are those in which the spouses have similar incomes. Couples most likely to receive a marriage bonus are those in which one spouse earns most or all of the couple’s income. Recent legislation reduced marriage penalties and increased marriage bonuses by Raising the standard deduction for couples to twice that for single filers Setting the income range of 10 and 15% tax brackets (but not higher ones) for couples to twice that for individuals. These changes became permanent with the recent “fiscal cliff” legislation.
27. Income Taxes The Marriage Penalty, 4 Marriage penalties and bonuses are not good policy, but they are expensive to eliminate. Keeping the marriage penalty reductions is estimated to cost more than $130 billion over 7 years. Fixing other sources of these penalties (such as high-income brackets that are not twice as wide for joint returns) would cost even more. These policies cut taxes by about 1 percent across all income levels, which means they are worth more in dollar terms to the richest taxpayers.
28. Income Taxes The Earned Income Tax Credit The largest “welfare” program in the U.S., called the Earned Income tax Credit, is run through the income tax. The EITC provides a tax credit based on income, up to maximum, with a higher credit for families with children. It was implemented in 1975 and has been greatly expanded since. The EITC is “refundable,” which means that it is paid even to households with no tax liability.
29. Income Taxes The Earned Income Tax Credit, 2 The EITC increases with income up to a certain amount, then holds steady up to another income level, then phases out. For example, the EITC for a married couple with 2 children in 2012 was 40% of earned income up to an income of $13,430 Exactly $5,236 for incomes between $13,430 and $22,300 Phased out between incomes of $22,300 and $47,162.

31. Income Taxes The Earned Income Tax Credit, 3 The EITC’s principal goal is to help low-income households by rewarding work. The EITC unequivocally increases the incentive to work in the phase in range of the credit (up to $13,430). However, the EITC discourages work in its phase-out range ($22,300 to $47,162), which involves more workers. Stretching the phase-out range would weaken this work disincentive for those currently affected, but would also bring in more workers and raise the program’s cost.
32. Income Taxes The Earned Income Tax Credit, 4 The EITC may also discourage marriage. The design of the program creates a huge marriage penalty. But empirical studies find little change in marriage rates due to this penalty.
33. Income Taxes Deductions for Homeownership The U.S. tax code gives 4 major benefits to homeowners: 1. Homeowners who itemize deductions are allowed to deduct interest paid on their mortgage. 2. Homeowners who itemize deductions are allowed to deduct their property taxes.
34. Income Taxes Deductions for Homeownership, 2 3. The implicit rent on a house, unlike the return on other investments, is excluded from taxable income. 4. When a homeowners sells her house, she may exclude up to $500,000 of capital gains if she (a) has maintained the home as her principal residence in two out of the preceding five years and (b) has not claimed this exclusion for the sale of another home during the previous two years.
35. Income Taxes Deductions for Homeownership, 3
36. Income Taxes Deductions for Homeownership, 4 Because these deductions favor high-income individuals, they mainly lead to larger homes or second-homes, not more homeownership. Because they lead to larger homes, they actually raise the price of housing. Many low-income homeowners do not itemize deductions and therefore do not benefit from these deductions at all.
37. Income Taxes Deductions for Homeownership, 5
38. Income Taxes Deductions for Homeownership, 6 Possible Reforms: 1. Replace the mortgage interest and property tax deductions with a tax credit. This would give benefits to low-income homeowners, even if they do not itemize. This would eliminate the extra subsidy to high-income homeowners. Moving to a credit of up to $1,400 for property taxes instead of a deduction, for example, would shift about half of the benefits to the bottom two-fifths of the income distribution, with no impact on federal revenue.
39. Income Taxes Deductions for Homeownership, 7
40. Income Taxes Deductions for Homeownership, 8 Possible Reforms: 2. Lower the limit on the allowable size of a home mortgage. Right now, homeowners can deduct interest on up to $1 million of mortgage debt,. Lowering this limit to $400,000 would lower the subsidy to the highest-income individuals. Recent estimates indicate that this change would have increased federal revenue by $30 billion between 2008 and 2012 and would yield nearly $60 billion over the subsequent five years.
