Who and what should be taxed?
Most people know what a tax is — a mandatory payment to the government. But ask them if they like taxes, and you are sure to get no for an answer. No one enjoys giving up hard-earned income to the government. For many people, the experience is downright painful. The physicist Albert Einstein is reported to have said, “ The hardest thing in the world to understand is the income tax.”
Many people share Einstein’s opinion. However, although taxes may be burdensome, they also make government possible. Without taxes, there could be no public institutions-no legislature, courts, or system of law enforcement. Therefore there would be no ordered society. “ Taxation,” said Supreme Court justice Oliver Wendell Holmes Jr., “ is the price we pay for civilization,”
Taxes have existed for as long as societies have been organized under common rule. In early civilizations, such as those of Egypt, Mesopotamia, and China, taxation took many forms. Farmers and craft workers had to give up a share of the goods they produced to the government, and traders were taxed on their commerce. In addition, people had to provide labor for building temples, city walls, and other public works. Taxes were paid in the form of goods and labor for centuries, but eventually these were replaced by taxes in the form of money.
Today taxes are collected and used for various purposes. They supply revenues to support the functions of government, such as national defense and criminal justice. They are used to pay for infrastructure, such as roads and bridges, and to fund welfare and public services, such as education and health care.
Taxes are also used to promote social and economic goals. For example, a tax may be placed on certain goods and services to limit their use. A tax on cigarettes or alcohol, for instance, can discourage their consumption. Taxes can also be used to redistribute income. For instance, higher taxes might be placed on one group, such as the wealthy, to provide benefits or services to another group, such as the poor.
Despite their many useful functions, taxes have never been popular with the citizens who pay them. Thomas Paine referred to taxes collected by Europe’s monarchs as “ plunder,” or stolen goods. Throughout history, resentment over taxes has given rise to tax protests, riots, and rebellions, including the rebellion that launched our country’s fight for independence.
Taxation was the main issue that sparked the American Revolution. At the time, Britain taxed the American colonies but gave them no representation in Parliament. The colonists believed they should have a say in how they were taxed. The popular slogan “ No taxation without representation” became a rallying cry for colonial discontent. As protests mounted, some members of Parliament called on the British government to change its tax policy. “ Your scheme yields no revenue,” declared the statesman Edmund Burke. “ It yields nothing but discontent, disorder, disobedience.”
After independence, the American people retained a cautious attitude toward taxation. Although they accepted the need for taxes, they also wanted to limit the government’s tax powers.
Some of these limits are written into the U.S. Constitution. Article I, Section 8, Clause I, which provides the basis for federal tax law, says that Congress shall have the power “ to lay and collect Taxes, Duties, Imposts and Excises.” But the clause goes on to limit this power in two key ways.
The framers of the Constitution also inserted a clause that limited the power of Congress to tax individual income. This clause was overridden in 1913, however, by passage of the Sixteenth Amendment, which allowed for the establishment of the federal income tax.
Shortly before Americans declared independence in 1776, Adam Smith published The Wealth of Nations, his famous book on economics. In it, Smith laid down four maxims, or guiding principles, of taxation that have influenced thinking about taxes ever since.
Equity. The first of Smith’s maxims is equity or fairness. In his view, wealthy citizens benefit most from government and can most afford to pay its costs. He wrote, ” It is not very unreasonable that the rich should contribute to the public expense, not only in proportion to their revenue, but something more than in that proportion.” In other words, Smith believed that the rich should pay a higher percentage of their income in taxes than do the poor.
Certainty. Smith’s second maxim is that the taxes a citizen owes should be “ certain, and not arbitrary.” He wrote, “ The time of payment, the manner of payment, the quantity to be paid, ought all to be clear and plain to the contributor.” Otherwise, government officials ma), be tempted to abuse the tax system for their own benefit.
Convenience. The third maxim is convenience. Smith wrote, “ Every tax ought to be levied at the time, or in the manner, in which it is most likely to be convenient for the contributor to pay it.” In other words, the tax system should not be overly complicated. Taxpayers should find the process of paying their taxes simple, straight forward, and predictable.
Efficiency. Smith’s fourth maxim — efficiency — is designed to keep the economic costs of the tax system to a minimum. Smith believed that taxes should produce maximum gain for the government, while causing minimum loss for taxpayers. “ Every tax,” he wrote, “ ought to ... take out and to keep out of the pockets of the people as little as possible over and above what it brings into the public treasury of the state.”
Most economists would agree in theory with Smith’s four maxims. Nevertheless, they often disagree about how to put those maxims into practice. One of the most hotly debated issues is the principle of tax equity, the idea that the tax system should be fair. Although economists support the principle of equity, they differ over how best to achieve it.
The crucial issue in the tax equity debate is who should pay. Economists offer two basic approaches to this problem: the ability- to-pay principle and the benefits- received principle.
The ability-to-pay principle mirrors Smith’s first maxim. It says that citizens should be taxed according to their income or wealth. People with higher incomes should pay more tax. People with lower incomes should pay less tax. Federal and state income taxes are based on this principle. For example, a lawyer who earns 5200,000 a year pays a higher percentage of income in taxes than does a teacher who earns $50,000 a year.
The benefits-received principle says that those who benefit from a particular government program should pay for it. For example, people who d rive should pay for the upkeep of the highway system. Gasoline taxes that fund road repairs are based on this principle, as are highway and bridge tolls.
One of the difficulties with devising a fair tax system is figuring out who bears the burden of a tax. To many people, the answer seems obvious. The producer or consumer who is legally required to pay the tax bears the burden, right’ Not necessarily. The economic burden of a tax — what economists call d"span class= vocab >tax incidence — may not fall on the person who pays the tax bill.
To see why, consider the tax on hotel rooms. Many state and local governments levy “ occupancy” taxes on the use of hotel and motel rooms. Hotel and motel owners are required to pay this tax revenue to the government. Most hotels simply add the tax, which is a percentage of the room rate, onto a customer’s bill. When this happens, the customer bears the burden. But this extra cost might cause some hotels to lose customers. If a hotel owner responds by lowering room rates to reduce the overall cost to the customer, then the hotel owner, not the customer, is bearing some of the burden of the tax.
As this example illustrates, tax incidence is affected by elasticity of supply and demand. Elasticity, YO LI may recall, is a measure of sensitivity to a change in price. In a market with very elastic demand, consumers are highly sensitive to price changes. A tax that raises prices may drive some consumers out of the market. If demand is inelastic, however, adding a tax to the price of a good or service will have much less effect on consumers’ willingness to buy.
Similarly, in a market with very elastic supply, producers are highly sensitive to price changes. A tax that raises the cost of doing business may drive some producers out of the market. I f supply is inelastic, however, adding taxes to other costs will not have much effect on producers’ willingness to sell a good or service.
In general, the burden of a tax will fall on the side of the market that is less elastic. If consumers are more likely to leave the market if prices rise, then producers will bear more of the tax burden. But if producers are more likely to abandon the market, the incidence of taxation will fall more heavily on consumers.
Many states and cities levy occupancy taxes on the use of hotel and motel rooms. Such taxes are typically charged to the customer. But if a hotel lowers its room rates to keep the cost to customers down, the incide nce of the tax falls at least in part on the hotel owner.
Any government hoping to create an equitable tax system must take tax incidence into account. Yet many people are unaware that tax burdens can, and often do, shift. As economist N. Gregory Mankiw points out,
Many discussions of lax equity ignore the ndirect effects of taxes and are based on what economists mockingly call the flypaper theory of tax incidence. According to this theory, the burden of a tax, like a fly on fly paper sticks wherever it first lands. This assumption, however, is rarely valid.
There is less debate among economists about Smith’s fourth maxim — efficiency. There are many ways to raise revenue through taxation. One tax system is considered more efficient than another if it raises the same amount of revenue at less cost to taxpayers. Obviously, a tax is, itself, a cost that taxpayers must bear. But taxes also impose two other kinds of costs: deadweight losses and the cost of tax compliance.
A deadweight loss occurs when the cost to consumers and producers from a tax — due to lost productivity or sales — is larger than the size of the tax revenue it generates. As economics writer Charles Wheelan put it, a deadweight loss “ makes you worse off without making anyone else better off.”
Taxes can create deadweight losses by reducing people’s incentives to be as productive as they would otherwise choose to be. For example, consider the effect of state and federal income taxes on a job seeker who is offered a position that involves long hours of overtime. If she could keep every dollar she would earn by working the extra hours, the job might look attractive. But knowing that she will have to pay at least a third of her earnings in taxes, she decides it is not worth working that hard. She turns down the job and continues looking for work. Not only is she still unemployed, but the economy has lost what she might have produced had she taken the job. That lost productivity is a deadweight loss.
Another source of tax inefficiency is the cost of complying with the tax code. Every year, U.S. taxpayers spend many hours, and often hundreds of dollars, preparing their income tax forms. Moreover, as Figure 12.2 shows, the overall cost of compliance has been rising yea rly. The time and money spent on tax preparation are resources that, if we had a more efficient tax system, could be used productively in other ways.
