Matthew Gikas directly appeals the sentence imposed by the district court 1 after he pleaded guilty to making and subscribing a false tax return. His counsel has moved to withdraw, and has filed a brief under Anders v. California, 386 U.S. 738, 87 S.Ct. 1396, 18 L.Ed.2d 493 (1967), arguing that the sentence was unreasonable. Gikas has submitted a pro se brief in which he argues that his sentence was disproportionate to that of his codefen-dants and that prosecutors lied to the Grand Jury and prosecuted him for impermissible reasons. We conclude that Gi-kas’s appeal waiver should be enforced and prevents consideration of his claims. See United States v. Scott, 627 F.3d 702, 704 (8th Cir. 2010) (de novo review of validity and applicability of appeal waiver); United States v. Andis, 333 F.3d 886, 889-90 (8th Cir. 2003) (en banc) (court should enforce appeal waiver and dismiss appeal where it falls within scope of waiver, plea agreement and waiver were entered into knowingly and voluntarily, and no miscarriage of justice would result). Having independently reviewed the record pursuant to Penson v. Ohio, 488 U.S. 75, 109 S.Ct. 346, 102 L.Ed.2d 300 (1988), we find no nonfriv-olous issues for appeal.

Accordingly, we affirm the judgment of the district court, and we grant counsel’s motion to withdraw.
