Number of Companies That Paid No Corporate Tax is Meaningless in Maryland, Other States

August 13, 2007

A few weeks ago, the Washington Post reported on new figures related to Maryland’s corporate tax system. The story cited a report by the Maryland Comptroller which showed that 68 out of the largest 132 Maryland employers paid no Maryland corporate tax in 2005. Naturally, many lawmakers and activists responded negatively, and they will surely use this data to argue that Maryland should enact combined reporting or some other measure to increase corporate tax revenues.

The fact that 68 out of 132 corporations paid no tax is a meaningless statistic, however, and tells us nothing about corporate tax sheltering. As such, these numbers should not be used by lawmakers to set corporate tax policy in Maryland or any other state.

There are a host of legitimate reasons why those 68 companies paid zero tax, including:

  • Maryland levies a corporate income tax, which is basically a tax on the profits of a company. If a company has no profit, it will pay no tax. What was the profitability of those 68 companies that paid no corporate taxes to Maryland in 2005? The Comptroller’s report doesn’t say.
  • Maryland allows corporate taxpayers to deduct net operating losses (NOLs) from a company’s taxable income. If an NOL reduces a company’s taxable income to zero, it can carry-forward the NOL for up to 20 years—which means that it is theoretically possible that some Maryland corporate taxpayers paid no corporate income tax in 2005 because they are carrying forward NOLs from as far back as 1985. The Comptroller’s report, however, does not address whether any of the 68 companies paid no income tax because of NOLs.
  • Maryland also allows corporations to reduce their tax liability through a number of tax credits and preferences. Depending on profitability and the carry-forward of NOLs, these preferences could easily take a company’s tax liability down to zero.
  • These reports create the appearance that companies are paying no state and local tax. As the Council on State Taxation so artfully (link is to 2006 version) points out each year, however, corporate income tax is only a fraction—and not a terribly large one at that—of the total taxes that companies pay to state and local governments each year. Companies also pay sales taxes, property taxes, and a host of other taxes, all of which add up to millions or billions of dollars each year. The Maryland Comptroller’s report does not address these other taxes paid by companies.

No one can seriously doubt that some companies are sheltering income to avoid corporate tax, and combined reporting is one possible tool that states can use to curtail erosion of their corporate tax base. But no state, including Maryland, should enact combined reporting because a report says that 68 out of 132 companies aren’t paying any corporate tax, because by themselves those numbers tell us nothing about corporate tax evasion.
