Summary

Civil tax penalties are an important tool to encourage taxpayer compliance with the tax laws. A number of civil tax penalties have fixed dollar amounts--a specific dollar amount, a minimum or maximum amount--that are not indexed for inflation. Because of Congress's concerns that civil penalties are not effectively achieving their purposes, we agreed to (1) determine the potential effect of adjusting civil tax penalties for inflation on the Internal Revenue Service's (IRS) assessment and collection amounts and (2) describe the likely administrative impact of regularly adjusting civil tax penalties on IRS and tax practitioners. GAO examined IRS data on civil tax penalties and conducted interviews with IRS employees and tax practitioners.

Adjusting civil tax penalties for inflation on a regular basis to maintain their real values over time may increase IRS collections by tens of millions of dollars per year. Further, the decline in real value of the fixed dollar amounts of civil tax penalties may weaken the deterrent effect of these penalties and may result in the inconsistent treatment of taxpayers over time. If civil tax penalty fixed dollar amounts were adjusted for inflation, the estimated increase in IRS collections would have ranged from $38 million to $61 million per year from 2000 to 2005. Almost all of the estimated increase in collections was generated by four penalties. These increases result because some of the penalties were set decades ago and have decreased significantly in real value--by over one-half for some penalties. According to those we interviewed, the likely administrative burden associated with adjusting the fixed dollar amounts of civil tax penalties for inflation on a regular basis would not be significant for IRS and would be low for tax practitioners. However, officials from the Office of Penalties, a relatively small office that would be responsible for coordinating the required changes among multiple IRS divisions, said that such adjustments might be considerable depending on the number of penalties being adjusted and would require a reprioritization of work. IRS officials said that the work required would be easier to implement with each subsequent update.
