Principles of Sound Tax Policy

The Standard Deduction

Poor Policy

Itemized Deductions

Tax code complexity can create real costs for taxpayers in the form of compliance burdens. Individuals spent 2.6 billion hours complying with IRS tax filing requirements in 2016.

The Tax Cuts and Jobs Act of 2017 simplified the federal tax code by doubling the standard deduction, which the Joint Committee on Taxation (JCT) estimated has resulted in nearly 30 percent fewer filers itemizing.

This has reduced complexity for filers who have decided they no longer need to track itemized deductions, which add significant time and complexity to the filing process.

Universal Savings Accounts

Poor Policy

Current U.S. Savings Account System

The sheer complexity of the American savings account system is astounding. As of 2020, there were 15 types of retirement accounts, each with an array of unique restrictions and requirements, including contribution limits, tax deduction limits, and guidelines for when savers can or must make withdrawals.

By increasing the complexity of the tax code, the web of requirements and restrictions across these accounts complicates saving decisions and disincentivizes saving altogether.

A simpler alternative would be the creation of universal savings accounts (USAs), which are simple, all-purpose accounts available to anyone, with no restrictions on either the timing or purpose of withdrawals. Savings are taxed only once, at the time of either contribution or withdrawal, and contributions are invested in assets such as bonds and equities, providing a return over time.

Retail Sales Taxes

Poor Policy

Gross Receipts Taxes

Gross receipts taxes (GRTs) cause “tax pyramiding,” meaning the same good is taxed multiple times in the process of being produced. Products with longer production chains are thus taxed more.

This disguises the burden of the tax, hiding it in the final price of goods. The “sticker rate” of a GRT—the rate set by law that policymakers advertise—is always lower than the “effective” rate, what consumers actually pay, after the tax has been shifted down the production chain.

A traditional retail sales tax, on the other hand, is only added to the final price of a good or service and is usually clearly delineated at the bottom of a receipt or invoice.

Sound Policy

Employee-side Payroll Taxes

Poor Policy

Employer-side Payroll Taxes

In the U.S., half of payroll taxes are remitted directly by employers (“employer-side” payroll taxes) while the other half are taken out of workers’ paychecks (“employee-side” payroll taxes).

Employee-side payroll taxes are relatively transparent: If you pull out your latest pay stub, you will likely see lines for two federal programs, Social Security (sometimes called FICA) and Medicare (MEDFICA), along with the amount that was taken out of your wages to fund each. Added together, these figures represent your total payroll tax liability for that pay cycle.

“Employer-side” payroll taxes, however, can be misleading. While remitted by businesses, they are almost entirely passed on to employees in the form of lower wages. This obscures who bears the burden of the tax and masks the cost to taxpayers of the programs it funds.

Sound Policy

Broad-based Consumption Taxes

Poor Policy

Digital Services Taxes

Recently, several countries, U.S. states, the EU, and the OECD have looked at ways to tax the digital economy via digital services taxes (DSTs).

These taxes can be discriminatory as they often single out specific industries and even specific business models through narrowly defined tax bases and arbitrary thresholds.

A more neutral approach would be to tax digital services like other goods and services, through value-added taxes (VATs) and retail sales taxes. Such broad-based consumption taxes that apply to all final consumption are neutral because they have little effect on consumer behavior and apply to all business models the same.

Sound Policy

Full Expensing for All Capital Investments

Poor Policy

Preferential Tax Credits and Exemptions

The principle of neutrality dictates that tax codes not pick winners and losers. Preferential tax credits and exemptions like those offered for purchasing electric vehicles, building sports arenas, or even filming movies in certain jurisdictions, do just that—they promote certain industries and activities over others.

A much more neutral, pro-growth solution to encouraging economic growth is what’s called “full expensing” by which all businesses, regardless of industry, are able to deduct the cost of all capital investments from their taxable income immediately.

Not only is full expensing for all investments non-distortionary, but when paired with the elimination of preferential credits, it can also result in a broader, simpler tax base overall, allowing governments to raise revenue more efficiently.

Sound Policy

Broad-based Consumption Taxes

Poor Policy

Cigarette Excise Taxes

Cigarette taxes have been a source of state revenue for decades but face consistent erosion as consumption declines. In most states, cigarette tax hikes are met with a momentary bump in revenue, followed by a drop-off in future years.

Conversely, one of the advantages of a broad-based consumption tax is its stability. All tax revenue is subject to economic cycles and changing taxpayer behavior, but broad-based consumption taxes experience considerably less volatility than taxes that target a narrow tax base, such as cigarette use.

Sound Policy

Permanent Policies in the TCJA

Poor Policy

Temporary Policies in the TCJA

Permanent tax policies promote stability and, in turn, lead to more pronounced economic effects than temporary policies. The Tax Cuts and Jobs Act (TCJA) of 2017 is a good case study for understanding the real-world implications of this.

The TCJA permanently reduced the corporate income tax rate from 35 percent to 21 percent but only temporarily allowed businesses to fully and immediately deduct their capital investments (what’s called “full expensing”).

While both policies increase economic growth by incentivizing investment, our modeling shows that the corporate income tax cut will have a significantly larger, positive effect on GDP in the long run, while full expensing will result in a short-term boost to GDP, followed by a dramatic drop-off as the policy expires.

Even the most pro-growth policies can have muted effects when implemented on a temporary basis. That’s because businesses make investment decisions by looking far into the future—much further than five years. The possibility that taxes on investment may increase in the near future will make businesses less likely to pursue big, long-term projects that often require years of sustained investment.
