Chapter 6 Funding the Public Sector

Introduction During his presidential campaign, Barack Obama stated that he would consider doubling the top tax rate on capital gains. Shortly after taking office, he proposed raising the top tax rate on capital gains by only one-third. Are there any practical limitations on how high governments can raise tax rates in hopes of obtaining more tax revenues? This chapter helps you understand the relationship between tax rates and tax revenues.

Learning Objectives Distinguish between average tax rates and marginal tax rates Explain the structure of the U.S. income tax system Understand the key factors influencing the relationship between tax rates and the tax revenues governments collect

Learning Objectives (cont'd) Explain how the taxes governments levy on purchases of goods and services affect market prices and equilibrium quantities

Chapter Outline Paying for the Public Sector Systems of Taxation The Most Important Federal Taxes Tax Rates and Tax Revenues Taxation from the Point of View of Producers and Consumers

Did You Know That ... The body of laws and rules governing the assessment and collection of U.S. federal taxes expands at an average rate of 1,000 words per day? To obtain the funds required to finance their operations, governments collect taxes from many different sources (property tax, sales tax, income tax, etc), hence the multitude of words written into a variety of statutes governing taxation.

Paying for the Public Sector Three sources of government funding Fees for government services, or user charges Taxes Borrowing

Paying for the Public Sector (cont'd) Government Budget Constraint The limit on government spending and transfer payments Imposed by the fact that every dollar spent must be provided for by taxes

Policy Example: Government Grinches Grab Gifts! During the Great Recession of the late 2000s, declines in incomes and spending resulted in sharp declines in income and sale taxes to U.S. state governments. To help raise government revenues, nearly half of U.S. states now impound unused balances on gift cards as user charges.

Systems of Taxation Tax Base The value of goods, services, wealth, or incomes subject to taxation Tax Rate The proportion of a tax base that must be paid to a government as taxes

Policy Example: Will U.S. Consumers Pour Their Dollars into a Federal VAT? U.S. States have levied sales taxes by applying tax rates to the dollar amounts that businesses receive on sales of goods and services. Recently, congressional leaders have suggested a new federal value-added tax (VAT), which are applied to every stage of an item’s production, so that the final price that a consumer pays would reflect the various federal VAT rates imposed during a good’s production.

Systems of Taxation (cont'd) Marginal Tax Rate The change in the tax payment divided by the change in income Marginal tax rate = change in taxes due change in taxable income

Systems of Taxation (cont'd) Tax Bracket A specified interval of income to which a specific and unique marginal tax rate is applied Average Tax Rate The total tax payment divided by total income

Policy Example: What the Typical Taxpayer Owes Out of the Next Dollar Earned Economists Robert Barro and Charles Redlick have calculated the marginal tax rate faced by an average U.S. resident. In 1920, the marginal income tax rate in the United States was just below 5 percent on average. Today, the marginal income tax rate, which includes the rates for federal income tax, state income tax and Social Security and Medicare income taxes, is nearly 36 percent.

Systems of Taxation (cont'd) Proportional Taxation A tax system in which, regardless of an individual’s income, the tax bill comprises exactly the same proportion Taxpayers at all income levels pay the same percentage of their income in taxes

Systems of Taxation (cont'd) Proportional taxation Marginal tax rate = Average tax rate Income Tax Rate Taxes $10,000 20% $2,000 $100,000 20% $20,000

Systems of Taxation (cont'd) Progressive Taxation A tax system in which, as income increases, a higher percentage of the additional income is paid as taxes

Systems of Taxation (cont'd) Progressive taxation Marginal tax rate > Average tax rate Income Tax Rate Taxes $0–$10,000 5% $500 $10,001–$20,000 10% $1,000 $20,001–$30,000 30% $3,000

Systems of Taxation (cont'd) Regressive Taxation A tax system in which as more dollars are earned, the percentage of tax paid on them falls A smaller percentage of income is taken in taxes as income increases

Systems of Taxation (cont'd) Regressive taxation: Social Security* Marginal tax rate < Average tax rate Income Tax Rate Taxes $100,000 10% $10,000 $200,000 5% $10,000 * No social security tax after $100,000 in income

The Most Important Federal Taxes Question What types of taxes do federal, state and local governments collect? Answers Federal government: individual income taxes, corporate income taxes, Social Security taxes, import and excise taxes State and local governments: sales taxes, property taxes, personal and corporate income taxes

Figure 6-1 Sources of Government Tax Receipts

The Most Important Federal Taxes The federal personal income tax Accounts for almost 44% of all federal revenue All U.S. citizens, resident aliens, and most others required to pay (includes income earned abroad) Rates paid rise as income increases

Table 6-1 Federal Marginal Income Tax Rates

The Most Important Federal Taxes (cont'd) Arguments for the progressive tax Redistribution of income Ability to pay Benefits received Counterargument No strong evidence of redistribution

The Most Important Federal Taxes (cont'd) Capital Gain The positive difference between the purchase price and the sale price of an asset You buy a share of stock for $5 and sell for $15: you have a capital gain of $10 Capital Loss The negative difference between the purchase price and the sale price of an asset

The Most Important Federal Taxes (cont'd) The corporate income tax Accounts for 12% of federal tax revenue and 2% of all state and local taxes collected Corporations are generally taxed on the difference between total revenues and expenses

Table 6-2 Federal Corporate Income Tax Schedule

The Most Important Federal Taxes (cont'd) Double taxation Corporation pays taxes on its profits Corporation declares a dividend on after-tax profits Dividend income is taxed

The Most Important Federal Taxes (cont'd) Retained Earnings Earnings that a corporation saves, or retains, for investment in other productive activities Earnings that are not distributed to stockholders Tax Incidence The distribution of tax burdens among various groups in society

The Most Important Federal Taxes (cont'd) Who really pays the corporate income tax? Tax incidence is distributed among Consumers Stockholders Employees

The Most Important Federal Taxes (cont'd) Social Security taxes Social Security rates today are imposed on earnings up to roughly $106,800 Contributions are 6.2% for employers and 6.2% for employees

The Most Important Federal Taxes (cont'd) Unemployment taxes Paid by employer 0.8% of first $7,000 of wages for employees earning more than $1,500 States may levy an additional tax up to 3% based on record of the employer

Tax Rates and Tax Revenues State and local governments Taxes imposed on goods and services yield more revenues than income taxes A fundamental issue is how to set tax rates to extract the largest possible payments

Tax Rates and Tax Revenues (cont'd) Sales Taxes Taxes assessed on the prices paid on a large set of goods and services Ad Valorem Taxation Assessing taxes by charging a tax rate equal to a fraction of the market price of each unit purchased

Tax Rates and Tax Revenues (cont'd) Static Tax Analysis Based on the assumption that changes in the tax rate leave the tax base unaffected Dynamic Tax Analysis Recognizes that higher tax rates may shrink the tax base

Tax Rates and Tax Revenues (cont'd) If the disincentive effects of higher tax rates are small, static analysis may give a fairly accurate estimate of the change in tax revenues resulting from a tax rate change As tax rates escalate, members of the public have a greater incentive to remove their activities from the tax base; a dynamic analysis would be necessary to determine the overall effect on government revenues

Figure 6-2 States with the Highest and Lowest Sales Tax Rates

Why Not … follow the example of states such as Maryland by creating a “millionaires” tax bracket with extra-high tax rates applied to incomes exceeding $1 million per year? The year after Maryland established a special millionaires tax bracket with a combined state and city tax rate of almost 10 percent, more than one-third of all the millionaires—people with annual incomes exceeding $1 million—responded by switching their formal residences to other lower-tax states, such as Florida and South Carolina. As a result, Maryland received almost $100 million per year less in taxes from millionaires.

International Policy Example: Ireland Collects Plenty of Corporate Taxes with a Low Rate Ireland’s corporate profits tax is only 12.5 percent, as compared to nearly 40 percent for the United States. The nation’s lower corporate profits tax rates boosted corporate profits and consequently tax revenues. During the 2000s, the Irish government collected an amount of corporate profits taxes equal to 3.6 percent of Ireland’s national income, while corporate profits taxes in the United States were 2.1 percent of U.S. annual income.

Tax Rates and Tax Revenues (cont'd) Maximizing tax revenues Dynamic tax analysis predicts ever-higher tax rates bring about declines in the tax base At sufficiently high rates the government’s tax revenues begin to fall off

Figure 6-3 Maximizing the Government’s Sales Tax Revenues

Taxation from the Point of View of Producers and Consumers Excise Tax A tax levied on purchases of a particular good or service Unit Tax A constant tax assessed on each unit of a good that consumers purchase

Taxation from the Point of View of Producers and Consumers (cont'd) Excise taxes on gasoline become added costs of production This shifts the supply curve up by the amount of the unit tax Consequently, the equilibrium price of gasoline rises and the equilibrium quantity declines

Figure 6-4 The Effects of Excise Taxes on the Market Supply and Equilibrium Price and Quantity of Gasoline

Taxation from the Point of View of Producers and Consumers (cont'd) Who Pays the Tax? In our example, the price that each consumer pays is $0.30 per gallon higher Therefore, consumers pay three-fourths of the excise tax and producers absorb the remainder

You Are There: A Business Owner Responds to a Marginal Tax Rate Increase A Utah physician, Wendell Gibby, M.D., owns a small company that produces medical imaging software. In response to an increase in his marginal income tax rate from about 40 percent to well over 50 percent, he reduces his production and cuts a few jobs in his company. The reductions in sales and thus Dr. Gibby’s income also mean less income for the government to tax.

Issues & Applications: Raising Capital Gains Tax Rates Shrinks the Tax Base Policymakers pressing for a higher tax rate on capital gains in order to generate more tax revenues rely on static tax analysis. But according to dynamic tax analysis, higher tax rates on capital gains may induce people not to realize these gains, thereby shrinking the capital gains tax base.

Figure 6-5 Capital Gains Tax Rates and Realized Capital Gains as a Percentage of Aggregate U.S. National Income

Summary Discussion of Learning Objectives Average tax rates versus marginal tax rates Average tax rate is the ratio of total tax payments to total income Marginal tax rate is the change in tax payments, induced by a change in total taxable income: applies to the last dollar earned

Summary Discussion of Learning Objectives (cont'd) The U.S. income tax system taxes personal and business income A tax system is progressive when marginal tax rate increases as income rises Contrasts with regressive system, in which higher-income earners pay lower marginal tax rates Under proportional taxation, the marginal and average rate are equal

Summary Discussion of Learning Objectives (cont'd) The relationship between tax rates and tax revenues Static tax analysis assumes that the tax base does not respond significantly to an increase in the tax rate Dynamic tax analysis reveals how an increase in the tax rate causes the tax base to decline

Summary Discussion of Learning Objectives (cont'd) How taxes on purchases of goods and services affect market prices and quantities A tax collected from the seller of a good will shift the supply curve up To the extent that the price rises, consumers pay a portion of the tax and sellers pay the remainder
