Although tax rate structures can be used, in part, to assess vertical equity, focusing on the tax rate structure solely ignores the role that the tax base plays in determining vertical equity. Indeed, focusing on the tax rate structure in evaluating a tax system is appropriate only if the tax base chosen (e.g., taxable income, purchases, property owned, etc.) accurately portrays a taxpayer’s ability to pay. This can be a rather strong assumption. Consider the sales tax. Although taxable purchases typically increase as taxpayers’ total incomes increase, total incomes typically increase at a much faster rate than taxable purchases. Thus, the gap between taxable purchases and total income widens as total income increases. The end result is that the effective tax rates for those with a greater ability to pay are lower than those taxpayers with a lesser ability to pay. Regressive tax rate structures are generally considered not to satisfy vertical equity (unless one is a strong advocate of the belief that those with a greater ability to pay simply should be paying a higher tax, albeit at a lower rate). In sum, evaluating vertical equity in terms of effective tax rates may be much more informative than simply an evaluation of tax rate structures.
Certainty means that taxpayers should be able to determine when to pay the tax, where to pay the tax, and how to determine the tax. It is relatively easy to determine when and where to pay the federal income tax and sales taxes. For example, individual federal income tax returns and the remaining balance of taxes owed must be filed with the Internal Revenue Service each year on or before April 15th (or the first business day following April 15th if the 15th falls on a weekend). Likewise, sales taxes are paid to retailers when items are purchased, and property taxes are typically paid annually to local governments. The ease of “how to determine the tax,” however, varies by tax system. Sales taxes are determined with relative ease – i.e., they are based on the value of taxable purchases. In contrast, income taxes are often criticized as being complex. What are taxable/nontaxable forms of income? What are deductible/nondeductible expenses? When should income or expense be reported? For many taxpayers (e.g., wage earners with few investments), the answers to these questions are straightforward. For other taxpayers (e.g., business owners, individuals with a lot of investments), the answers to these questions are nontrivial. Constant tax law changes enacted by Congress also add to the difficulty in determining the proper amount of income tax to pay. These changes can make it difficult to determine a taxpayer’s current tax liability much less plan for the future.
Eliminating withholding would violate the convenience criterion – i.e., a tax system should be designed to facilitate the collection of tax revenues without undue hardship on the taxpayer or the government (i.e., a tax system should make collection as easy as possible). Eliminating withholding would most likely have slowed collection of taxes and increased taxpayer aggressiveness (or tax evasion). Prior research suggests that taxpayers are more likely to take more aggressive tax positions when they owe additional taxes when filing their return.
This statement ignores the economy criterion from the taxpayer’s perspective. The income tax is often criticized for the compliance costs imposed on the taxpayer. Indeed, for certain taxpayers, record-keeping costs, accountant fees, attorney fees, etc. can be quite substantial. Advocates of alternative tax systems often challenge the income tax on this criterion.
