In 2005, Montero earned over $160,000 working for Dell Products. He filed suit against the Government in federal district court, seeking a refund of all federal taxes that Dell withheld from his pay ($27,929 in income tax and $8,104 in FICA tax). He contends that the “unprivileged private-sector remuneration” that he received from Dell does not constitute taxable wages. He also sought an injunction enjoining the Government from “future abuse” and an unspecified amount of money damages.

The district court dismissed the complaint for lack of jurisdiction because Montero had not satisfied the jurisdictional prerequisites for filing a tax refund suit in federal court (payment of assessed tax liability in full and timely filing of an administrative claim for a refund with the Internal Revenue Service). See 28 U.S.C. 1346(a)(1); 26 U.S.C. 7422(a); Flora v. United States, 362 U.S. 145, 177, 80 S.Ct. 630, 4 L.Ed.2d 623 (1960). Montero argues that these jurisdictional prerequisites apply only to “taxpayers” and, therefore, do not apply to him because he is a “non-taxpayer.” These arguments are patently frivolous and devoid of any merit whatsoever. Accordingly, the judgment of the district court is in all respects AFFIRMED.

Montero’s “Motion to Improve Legibility of Currently Illegible Portions of the Record on Appeal” is DENIED as moot.

The Government’s motion for a lump-sum sanction of $8,000, in lieu of calculating the costs and attorney’s fees it incurred in responding to Montero’s frivolous appeal, is GRANTED. This court has approved similar awards in similar cases because it “saves the government the additional cost of calculating its expenses, and also saves the court the time and expense of reviewing the submission of costs.” *739 Parker v. Commissioner, 117 F.3d 785, 787 (5th Cir. 1997); see also Smith v. United States, 2008 WL 5069783, at *2 (5th Cir. 2008) (unpublished) (awarding lump sum sanction of $8,000 against taxpayer for filing a frivolous appeal) Wallis v. Commissioner, 203 Fed.Appx. 591, 594 (5th Cir. 2006) (unpublished) (same).

AFFIRMED; SANCTIONS IMPOSED.
