MEMORANDUM*
COMMISSIONER OF INTERNAL
REVENUE,
Respondent-Appellee.
Appeal from a Decision of the
United States Tax Court
Submitted September 17, 2024**
Before: WARDLAW, BADE, and H.A. THOMAS, Circuit Judges.
David Gilmartin appeals pro se from the Tax Court’s order, following a
bench trial, upholding the Commissioner of Internal Revenue’s determination of
income tax deficiencies, and imposing a penalty under 26 U.S.C. § 6673. We have
jurisdiction under 26 U.S.C. § 7482(a)(1). We review de novo the Tax Court’s

legal conclusions and for clear error its factual determinations. Hardy v. Comm’r,
181 F.3d 1002, 1004 (9th Cir. 1999). We affirm.
The Tax Court properly upheld the Commissioner’s deficiency
determination because the Commissioner presented “some substantive evidence”
that Gilmartin failed to report income and Gilmartin did not submit any relevant
evidence “showing that the deficiency was arbitrary or erroneous.” Id. at 1004-05;
Grimes v. Comm’r, 806 F.2d 1451, 1453 (9th Cir. 1986) (“There can be no doubt
that the tax on income is constitutional” and “income includes gain derived from
capital, from labor, or from both combined” (citation and internal quotation marks
omitted)); Olson v. United States, 760 F.2d 1003, 1005 (9th Cir. 1985) (“This court
has repeatedly rejected the argument that wages are not income as frivolous”).
The Tax Court did not abuse its discretion by imposing against Gilmartin a
$5,000 penalty under 26 U.S.C. § 6673 for maintaining frivolous positions despite
the Tax Court’s warnings. See Wolf v. Comm’r, 4 F.3d 709, 716 (9th Cir. 1993)
(setting forth standard of review and concluding that the Tax Court was within its
discretion in imposing penalties under § 6673 against taxpayer who pursued
frivolous litigation following warning).
Gilmartin’s motions for an extension of time to file a reply brief (Docket
Entry Nos. 68, 70, 71) are denied as moot.
AFFIRMED.
