Kennedy's Payroll Tax Gamble

On December 11 Sen. Edward Kennedy (D-Mass.) gave a widely reported speech in which he outlined a liberal legislative agenda. Among his initiatives is a proposal to reduce the Social Security tax by eliminating the limit on taxable wages.

  • At present, workers pay Social Security taxes only on wages up to $68,400.

  • Under the Kennedy plan, workers would pay Social Security taxes on all of their earned income, with no maximum.

  • Senator Kennedy estimates that the additional revenues from this proposal would allow the payroll tax rate to be reduced from 6.2 percent to 5.3 percent.

According to the White House Bulletin, many Republicans in Congress are intrigued by the Kennedy proposal. It quotes an unnamed congressional GOP strategist as saying it "threatens to sweep the place" and "there is a real good chance" that there may be action on the issue this year. The report further indicates that Sen. Kennedy's office has discussed the idea with the White House and gotten "encouraging words."

The rationale for the Kennedy plan is that it would reduce payroll taxes for all workers earning less than $80,000 per year. This is important because for most workers the payroll tax is the single biggest tax they pay, exceeding their federal income taxes. Moreover, the payroll tax is a significant cost of business, forcing companies to pay higher wages. Small businesses, in particular, are especially hard-hit by the payroll tax because the self-employed must pay both the individual and business share of the tax, for a total of 12.4 percent.

Senator Kennedy says his plan would not increase the federal deficit or threaten the Social Security system's finances, because it would be revenue neutral. Therefore, on the face of it, it appears to be a win-win plan, cutting taxes for most workers while raising taxes for only for the rich.

There are two major problems with this logic, however. The first is that Kennedy's plan will lead to higher benefits for the rich. The reason is because benefits are tied to taxable wages. If the amount of a worker's taxable wages increases, as it would under the Kennedy plan, they will receive higher benefits when they retire. According to economist Eugene Steuerle of the Urban Institute, "benefit gains for those with very high incomes would be significant." In fact, the purpose of the taxable earnings limit is precisely in order to keep rich people from receiving excessive Social Security benefits.

The second problem with the Kennedy plan is the disincentive effects of the higher tax rate for those with upper incomes. It will discourage work effort among those with high wages, such as doctors. And it will encourage corporate executives to take more of their compensation in the form of "unearned" income not subject to the payroll tax, such as stock options. Of course, low and moderate income workers will have a greater incentive to work and earn taxable income. However, economist Steve Entin of the Institute for Research on the Economics of Taxation estimates that "on an income-weighted basis, there would be a net reduction in work incentives economy-wide."

Consequently, Entin believes that the Kennedy plan is not revenue neutral. He calculates that the government will receive only 75 percent of the revenue Senator Kennedy estimates. Moreover, it does not appear that Senator Kennedy has taken any account of the higher benefits that will be paid out. Therefore, the plan would significantly increase the federal budget deficit and worsen the finances of the Social Security system. Given the already precarious state of Social Security's finances, the Kennedy plan too big a gamble to take.
