Montero v. Commissioner — Fifth Circuit upheld a frivolous-return penalty and $25,000 Tax Court sanction

Unreported / Non-Citable

Background

Adolfo Sandor Montero worked for Dell Technologies Inc. in 2018 but reported no taxable wage or salary income on his Form 1040. He attached a substitute Form W-2 stating that he received no compensation and asserting that Dell had incorrectly characterized its payments to him as taxable wages.

The Commissioner of Internal Revenue deemed the return frivolous and assessed a $5,000 penalty under 26 U.S.C. § 6702(a). After the IRS upheld the penalty and its proposed levy following a collection due process hearing, Montero sought Tax Court review. The Tax Court sustained the penalty, imposed an additional $25,000 sanction under 26 U.S.C. § 6673(a)(1), and denied Montero’s motion to vacate.

The Court’s Holding

The Fifth Circuit affirmed. It rejected Montero’s renewed argument that compensation from a private employer is not taxable unless connected to the federally privileged activity of working for or doing business with the United States. The court explained that it had repeatedly rejected the theory that federal income tax applies only to special privileges rather than income generally.

The panel also held that the Tax Court did not abuse its discretion by imposing the maximum $25,000 sanction authorized by § 6673(a)(1). Montero continued to advance the same frivolous position despite repeated warnings and prior decisions rejecting his arguments and sustaining penalties and sanctions against him.

Key Takeaways

• Wages paid by a private employer are not exempt from federal income tax merely because the work lacks a connection to the federal government.
• A frivolous return may trigger a $5,000 penalty under 26 U.S.C. § 6702(a).
• The Tax Court may impose a sanction of up to $25,000 when a taxpayer advances a frivolous or groundless position, particularly after repeated warnings.

Why It Matters

The decision reinforces the Fifth Circuit’s settled rejection of arguments that federal income taxation is limited to government-connected or specially privileged activities. Repeating those theories after courts have expressly rejected them can expose a taxpayer to substantial sanctions in addition to the underlying tax-related penalty.

Although the Commissioner did not request appellate sanctions under Federal Rule of Appellate Procedure 38, the Fifth Circuit warned Montero that further frivolous appeals could justify additional sanctions.
