The Congressional Budget Office (CBO) released a report on effective marginal tax rates for low-income workers.[1]
An effective marginal tax rate as defined by the CBO is the change in taxes and change in government benefits associated with increases in income. Because tax rates and government benefits change as income changes, an individual’s effective marginal tax rate can rise and fall drastically as he works more hours.
While much focus in the past two years has been on the top end of the income scale—the “Buffett Rule,” the “1 percent”—the effects of taxation and government benefits are severe among the bottom 1 percent as well. With marginal effective tax rates exceeding 60 percent in many cases, the tax and benefit structure actively discourages earned success.
There are five lessons from the CBO report that policymakers should learn.
The architects of policies such as Section 8 housing or food stamps never intended to create a poverty trap. But as benefits are added up, the combined effect is to steadily devalue earned income.
Chart 1, adapted from the CBO report’s Summary Figure 1, shows the futility of work for a single parent with one child. If he does not work at all, he receives $19,300 in government benefits. If he instead earns a salary of $30,000—which is full-time work at $15 per hour—he has disposable income of $28,000. This means that he is working full-time for only $8,700 per year more than if he did not work at all, making his effective take home wage $4.35 per hour ($8,700/2,000 hours per year). Is it rational to expect someone to work hard for such a low wage?
Most government benefits aimed at the poor have “static” justifications. That is, a program to provide health care to the poor is predicated on their current poverty. But it may have important prospective effects. Once the program comes into existence, it changes the costs and benefits of staying in school, working, and even marrying. Some of the worst policies of the 20th century were those that penalized responsible fatherhood, as the Moynihan Report[2] famously addressed in 1965.
Those who favor raising the minimum wage generally appeal to the idea that those working low-paying jobs need to increase their consumption more than others. But the CBO’s research shows that in the relevant income range, the marginal effective tax rate is above 65 percent for the example single parent (Chart 2, adapted from the CBO report’s Figure 2, page 7). Thus, a minimum wage increase of 10 percent would increase the single parent’s take-home pay by less than 4 percent—if he kept his job, which is no sure thing, since increases in the minimum wage hurt the job prospects of such workers.[3]
Meanwhile, the arguments for lowering the minimum wage are strong: Competitive wages employ more people, keep more businesses open, and employ those in greatest need of a job.
The phase-out of “Premium Assistance Credits” significantly raises the marginal effective tax rate for a single parent earning between $22,000 and $62,000 per year (see CBO, Figure 7, page 26). This is an example of a program that raises marginal tax rates without “raising taxes.” The government collects less revenue than before—in fact, it pays out a handsome benefit—but discourages work even more.
As The Heritage Foundation has argued elsewhere,[4] poverty statistics that measure only earnings are poorly defined. The CBO report shows that even for some of those with no earnings at all, social programs in the U.S. provide enough disposable income to elevate them above the poverty line. The example single parent, when earning nothing at all, receives benefits worth 128 percent of the federal poverty line.
Beyond the substantive lessons that can be drawn from the report, note four technical insights:
The high marginal effective tax rates, and their effects on regular people, have long been noted by economists.[5] In the United Kingdom, experts recognized the poverty trap created by government policy and initiated a major reform of the social welfare system, which will begin taking effect in 2013.[6] Casey Mulligan has contrasted the British simplification of welfare with growing complexity in the United States.[7]
With the tax code ripe for reform, policymakers should remember: Marginal tax rates are dangerously high for some on the lower end of the pay scale.
