OPINION

Cynthia Ann Schlosser and James K. Schlosser appeal the United States Tax Court’s decision granting the Commissioner’s motion for summary judgment. For the reasons that follow, we will affirm the Tax Court’s decision.

The procedural history of this case and the details of Schlossers’ claims are well-known to the parties, set forth in the Tax Court’s opinion, and need not be discussed at length. Briefly, both parties failed to file income tax returns in 1994 and the Internal Revenue Service (“IRS”) sent both parties a notice of intent to levy and notice of right to a collection-due-process (“CDP”) hearing. The parties requested a CDP and stated that they were not required to file income tax forms and that they did not have taxable income. The IRS Appeals Office issued a notice of determination to each party upholding the proposed levy actions and the lien filings. Appellants next filed an appeal to the Tax Court challenging the notices of determination. In their petitions, Appellants alleged that they were not required to file federal income tax returns, that they had no income, and that they were not subject to “the jurisdiction of the United States”. The Commissioner filed motions for summary judgment which the Tax Court granted. The Tax Court also imposed a penalty of $1000 pursuant to I.R.C. § 6673. Appellants filed separate appeals challenging the Tax Court’s decision. The Commissioner filed a motion to consolidate the cases which was granted. The Commissioner has also filed a motion requesting that Appellants pay damages and costs pursuant to Fed. R.App. P. 38.

*171 We have jui’isdiction pursuant to 26 U.S.C. § 7482(a)(1). We exercise plenary review over the Tax Court’s conclusions of law, and review the Tax Court’s factual findings for clear error. See PNC Bancorp, Inc. v. Comm’r of Internal Revenue, 212 F.3d 822, 827 (3d Cir. 2000). We review the Tax Court’s imposition of a penalty under § 6673 for abuse of discretion. See Sauers v. Comm’r of Internal Revenue, 771 F.2d 64, 65 (3d Cir. 1985).

Appellants argue that the Tax Court erroneously granted summary judgment because there were material facts in dispute. See Dahlstrom v. Comm’r of Internal Revenue, 85 T.C. 812, 820-21 (1985) (discussing summary judgment standard). Appellants, in the Tax Court, raised the same baseless arguments raised by previous tax protestors. See e.g., United States v. Sloan, 939 F.2d 499, 500 (7th Cir. 1991); United States v. Collins, 920 F.2d, 619, 629-631 (10th Cir. 1990). Appellants’ arguments are patently frivolous and the Tax Court did not err in granting the Commissioner’s motion for summary judgment. Furthermore, Appellants were warned numerous times that their continued frivolous arguments could result in the imposition of monetary penalties. Therefore, we discern no abuse of discretion in the Tax Court’s imposition of a § 6673 penalty on Appellants.

Accordingly, we will affirm the judgment of the United States Tax Court.

Under Fed. R.App. P. 38 a court of appeals may award damages and costs to an appellee if it determines that an appeal is frivolous. “This court has been reluctant to classify appeals as frivolous,” and has reserved award of fees and costs for extreme cases where appeals were without doubt devoid of merit. Hilmon Co. (V.I.) Inc. v. Hyatt Intern., 899 F.2d 250, 253 (3d Cir. 1990). Because the Sehlossers’ appeals raise arguments that have been repeatedly deemed frivolous, we grant the Government’s motion and award costs in the amount of $1,000 against each Appellant.
