Frivolous Position Penalty Under IRC § 6673: Swanson Case

08.20.2025

Taxpayers who present baseless arguments in disputes with the IRS risk not only losing their cases but also incurring significant penalties. The case Swanson v. Commissioner examines the Tax Court’s recent application of the frivolous position penalty under IRC § 6673. This case serves as a reminder of the court’s strict stance on taxpayers who engage in behavior deemed frivolous or aimed at delaying proceedings.

 The Tax Court upheld a penalty of $25,000 against Swanson, citing repeated use of arguments that lacked legal merit and wasted judicial resources. The case highlights the importance of avoiding frivolous claims and adhering to established legal principles when disputing tax liabilities.

  1. Primary Provisions of IRC § 6673:

Section 6673 allows the Tax Court to impose penalties of up to $25,000 in cases where:

  • The taxpayer institutes proceedings primarily for delay.
  • The taxpayer’s position is frivolous or groundless.
  • The taxpayer fails to pursue available administrative remedies.

In Swanson case, the court found that all three conditions were met, justifying the maximum penalty.

  1. Delay as a Strategy:

The court determined that Swanson’s repeated filing of frivolous motions and reliance on previously discredited arguments constituted an intentional delay tactic. IRC § 6673 specifically addresses this issue by penalizing taxpayers who engage in actions that obstruct the judicial process.

  1. Frivolous Arguments Presented:

 Swanson advanced arguments such as:

  • The unconstitutionality of income tax.
  • Claims that wages are not taxable income.

These arguments have long been rejected by the Tax Court and other courts. The decision emphasized that relying on well-established frivolous positions wastes judicial resources and undermines the integrity of the tax system.

  1. Failure to Pursue Administrative Remedies:

Swanson ignored opportunities to resolve the dispute administratively, including failing to provide substantive documentation during the IRS appeals process. The court viewed this as an unreasonable approach to resolving tax disputes, further warranting the penalty. 

  1. Judicial Precedents Referenced:

The court cited previous cases where similar frivolous arguments resulted in penalties, reinforcing the Tax Court’s consistency in addressing such conduct. These precedents serve as warnings to taxpayers who may consider advancing unsupported claims.

The Tax Court noted that taxpayers who adopt frivolous positions create a risk of encouraging others to evade compliance. By imposing substantial penalties, the court aims to deter such behavior and preserve the integrity of the tax system.

 

Relevance to Tax Professionals

Tax professionals must prioritize ethical representation by educating clients on the consequences of presenting frivolous claims. Guiding clients to avoid baseless arguments protects them from penalties under IRC § 6673 and upholds the advisor’s professional integrity. By ensuring that positions taken in disputes are well-founded and supported by credible evidence, practitioners contribute to the efficient functioning of the tax system and reduce the risk of unnecessary litigation.

 Cases like Swanson highlight the critical role tax advisors play in maintaining compliance and discouraging misuse of the legal process. By leveraging such precedents, professionals can illustrate the potential pitfalls of advancing unsupported arguments, reinforcing the importance of adhering to established legal standards and ethical advocacy in tax disputes.
