The Pease Limitation on Itemized Deductions Is Really a Surtax

In addition to a series of taxA tax is a mandatory payment or charge collected by local, state, and national governments from individuals or businesses to cover the costs of general government services, goods, and activities. rate increases, 2013 also brought back a more subtle tax increase for high income earners: the Pease limitation on itemized deductions. This provision, named after the late Congressman Donald Pease, reduces the value of itemized deductions for high income taxpayers. It works by reducing the value of a taxpayer’s itemized deductions by 3 percent for every dollar of taxable incomeTaxable income is the amount of income subject to tax, after deductions and exemptions. For both individuals and corporations, taxable income differs from—and is less than—gross income. above a certain threshold ($254,200 single; $305,050 married). The phase-out of the value of itemized deductions is capped at 80 percent of the total value of itemized deductions.

Due to its structure, Pease is not really a limitation on itemized deductions, but rather a stealth surtaxA surtax is an additional tax levied on top of an already existing business or individual tax and can have a flat or progressive rate structure. Surtaxes are typically enacted to fund a specific program or initiative, whereas revenue from broader-based taxes, like the individual income tax, typically cover a multitude of programs and services. on high-income individuals. In tax reform, Pease should be repealed, but if some limitation on itemized deductions is politically necessary, a cap on certain itemized deductions would be better.

How Pease Works

A taxpayer earning $500,000 in taxable wage income would be hit with Pease. This taxpayer would be facing the top marginal income tax rate of 39.6 percent. Let’s also assume that the taxpayer lives in Michigan and faces a top marginal rate of 4.25 percent. This taxpayer would be able to deduct the income taxes paid to Michigan against his federal income tax, thus reducing the federal marginal rate by 1.68 percent to 37.92 percent.

Pease would undo some of the benefit from this deduction. In this case, it would reduce the value of the state and local income tax deductionA tax deduction is a provision that reduces taxable income. A standard deduction is a single deduction at a fixed amount. Itemized deductions are popular among higher-income taxpayers who often have significant deductible expenses, such as state and local taxes paid, mortgage interest, and charitable contributions. by 3 percent on the next dollar of income and thus boosting his taxable income by an extra 3 cents. The effect of this is an increase in his marginal tax rateThe marginal tax rate is the amount of additional tax paid for every additional dollar earned as income. The average tax rate is the total tax paid divided by total income earned. A 10 percent marginal tax rate means that 10 cents of every next dollar earned would be taken as tax. of 1.18 percent (3 percent of the 39.6 marginal rate). The taxpayer’s marginal rate increases from 42.1 percent to 43.35 percent.

This 1.18 percent increase in the taxpayer’s marginal rate lasts until Pease has phased-out 80 percent of the value of his itemized deductions.

Pease is Really a Hidden Surtax

However, in reality, most taxpayers will never hit the 80 percent cap. Itemized deductions usually increase as an individual’s income increases. In the example above, the taxpayer’s itemized deductionItemized deductions allow individuals to subtract designated expenses from their taxable income and can be claimed in lieu of the standard deduction. Itemized deductions include those for state and local taxes, charitable contributions, and mortgage interest. An estimated 13.7 percent of filers itemized in 2019, most being high-income taxpayers. (the state and local income tax deduction) will always increase as his income increases because he will continue to pay more in state income taxes. As a result, Pease will continue to phase out 3 percent of every additional dollar of a taxpayer’s itemized deductions to infinity.

Pease Really Doesn’t Make Sense

From a tax policy perspective, Pease’s structure makes little sense for two main reasons.

First, if lawmakers wanted to increase the marginal tax rate on high income individuals, it would have made more sense to just increase marginal tax rates. That would have created the extra bit of progressivity without adding additional complexity. In addition, taxpayers would be more aware of the fact that the federal top marginal individual income taxAn individual income tax (or personal income tax) is levied on the wages, salaries, investments, or other forms of income an individual or household earns. The U.S. imposes a progressive income tax where rates increase with income. The Federal Income Tax was established in 1913 with the ratification of the 16th Amendment. Though barely 100 years old, individual income taxes are the largest source of tax revenue in the U.S. rate is not actually 39.6 percent, but 40.8 percent.

Second, if reducing the value of certain itemized deductions was the goal, Pease is a less efficient means of doing so than other methods. Since Pease is connected to a taxpayer’s AGI and not the value of itemized deductions, it doesn’t really change the marginal benefit of deductions. If reducing the subsidy effect of a deduction were the goal, it would be better to target certain deductions that have little economic justification with a cap.

A cap would also be more economically efficient, since it would have a smaller effect on marginal rates, creating less of a work disincentive.

Replace or Repeal

While some itemized deductions could be considered real loopholes, many are reasonable. They are there to define taxable income for taxpayers and deal with any potential double-counting of economic activity that may occur when money is transferred from one person or business to another (e.g. Home mortgage interest deductionThe mortgage interest deduction is an itemized deduction for interest paid on home mortgages. It reduces households’ taxable incomes and, consequently, their total taxes paid. The Tax Cuts and Jobs Act (TCJA) reduced the amount of principal and limited the types of loans that qualify for the deduction. ). Limiting these could create double-taxation and can have detrimental effects on the economy.

In future discussions about tax reform, limiting certain itemized deductions for high-income taxpayers will undoubtedly come up as a means of maintaining progressivity. If it does, lawmakers should seek to replace Pease with something more reasonable at the very least.
