What You’ll Learn
- Discover why there are better and worse ways for governments to raise a dollar of revenue.
- Compare the economic impact of the three basic tax types—taxes on what you earn, buy, and own—including three specific taxes within each category.
- Learn about the basics of “dynamic scoring,” one tool economists can use to compare the economic and revenue impact of different tax policies.
There are better and worse ways to raise a dollar of revenue. That’s because no two taxes impact the economy the same.
One way to think about this is as a hierarchy: Which taxes are most and least harmful for long-term economic growth? This hierarchy is determined by which factors are most mobile, and thus most sensitive to high tax rates—in other words, what economic activities, if taxed, can easily be moved, reduced, or otherwise changed to avoid that tax?
Taxes on the most mobile factors in the economy, such as capital, cause the most distortions and have the most negative impact. Taxes on factors that can’t easily be moved, such as land, are the most stable and least distortive.
It’s relatively easy for someone to invest less to avoid a capital gains tax, for example. It’s much harder for someone to pull up stakes and move their home to avoid a property tax. This difference is why capital gains taxes distort people’s decisions, and thus the economy, more than property taxes.
Taxes on what you earn
Corporate Income Taxes
Corporate income taxes are taxes on business profits earned by C corporations. The corporate income tax directly increases the cost of making investments in capital, like machinery and equipment, which businesses and workers use to be more productive. When businesses and workers are more productive, the economy grows. So, by increasing the cost of making investments, the corporate income tax discourages investment and productivity growth, creating one of the largest negative impacts on economic growth compared to other taxes.
Individual Income Taxes
Individual income taxes are applied to wages and salaries, business income from pass-through businesses like sole proprietorships and LLCs, and investment income. High marginal tax rates, the amount of additional tax paid for every additional dollar earned as income, reduce individual incentives to work and business incentives to invest. That means individual income taxes also have a negative effect on the economy.
Payroll taxes are paid on the wages and salaries of employees to finance social insurance programs like Social Security, Medicare, and unemployment insurance. Payroll taxes apply only to labor income, and not to business income like the previous two forms of tax. For this reason, payroll taxes are one of the least harmful ways to raise revenue, as the supply of labor is less responsive to taxation than the supply of capital. That said, it’s important to note that employees bear the burden of payroll taxes, resulting in lower wages.
Taxes on what you buy
Gross Receipts Taxes
Gross receipts taxes are applied to a company’s gross sales without allowing any deductions for costs. Unlike a sales tax or a value-added tax (VAT), gross receipts taxes are applied to business-to-business transactions and final consumer purchases. Since the tax is applied at each transaction in a production chain, without allowing for any deductions, it leads to tax pyramiding, where the many layers of tax are built into the final price of the good. By providing an advantage to businesses with short production chains, while harming those with long production chains, gross receipts taxes distort business decisions and the economy.
Excise taxes are imposed on a specific good or activity, such as cigarettes, alcohol, and fuel. Because of their narrow base (applying a tax to a small selection of goods or services) excise taxes distort production and consumption choices. Sometimes this distortion is by design. For example, a tax on cigarettes to discourage smoking; however, this distortion makes excise taxes an inefficient source of revenue. Excise taxes with broader bases, or those levied in direct connection with the consumption of public goods, like gas taxes paying for road usage, better resemble pure consumption taxes and have less distortive effects.
Sales taxes are imposed on retail sales of goods and services. Ideally, sales taxes are imposed on all final retail sales of goods and services, but not on intermediate business-to-business transactions in the production chain, as in the case of gross receipts taxes. Sales taxes are less distortive than capital and income taxes because they do not affect decisions to work or invest, and when appropriately structured, they do not lead to tax pyramiding or changes in consumption.
Taxes on what you own
Wealth taxes are imposed annually on an individual’s net wealth. Net wealth is calculated by taking the market value of their total owned assets—the price those assets would get if sold—and subtracting their liabilities—everything that person owes, including loans, mortgages, and other debts. Wealth taxes place a high tax burden on the normal return to capital (the amount required for an investor to break-even on an investment) and a lighter burden on the supernormal returns to capital (amounts above and beyond the normal return); this is the opposite of ideal tax policy. By placing a higher burden on the normal return to capital, wealth taxes distort investment decisions and can alter entrepreneurship, venture capital funding, and even where talent is located (in Silicon Valley vs. Hong Kong, for example).
Estate taxes are levied on the value of property that is transferred to heirs upon the death of the original owner and can be thought of as a one-time wealth tax. These taxes lead to unproductive tax planning, increase the tax burden on investment by encouraging people to consume their income rather than invest it, and may have negative effects on entrepreneurship.
Property taxes can be levied on immovable or “real” property (i.e., land and buildings) and personal property (i.e., cars, machinery, office equipment, etc.). When properly structured, property taxes can be relatively economically efficient and transparent, such as when they apply to immovable property, like annual taxes on land and buildings. Taxes on immovable property have a relatively small effect on decisions to work and invest, though they can impact where a person or business chooses to locate. Because personal property is much more mobile, and thus more sensitive to taxation, personal property taxes distort investment decisions, complicate business tax compliance, and reduce economic growth.
Bang for Your Buck: Ranking 5 Hypothetical Tax Changes
Instead of focusing on the relative harm of different tax types, think about it in the reverse: Which taxes can be reduced to improve the economy? One way to answer this question is to use dynamic scoring to produce what we refer to as a “bang for your buck” analysis—a ranking of how much economic growth is produced per dollar of revenue forgone by different tax reductions.
The chart below considers five U.S. federal tax policy changes and the resulting effect on the size of long-run economic output, including a change in the corporate income tax base called full expensing; a 1 percentage-point reduction in the corporate income tax; a 1 percentage-point reduction in the individual income tax rate for all tax brackets; an increase in the maximum child tax credit to $2,500; and a decrease in the capital gains tax rate of 5 percentage points.
As you can see below, cutting the capital gains tax rate is the least efficient option to produce economic growth. Dollar-for-dollar, full expensing, which allows companies to fully and immediately deduct the cost of all new investments, is the most efficient way for policymakers to generate economic growth through the tax code.
