Before WOLLMAN, COLLOTON, and GRUENDER, Circuit Judges.
                        ___________

PER CURIAM.

       Richard Mellor appeals pro se the district court’s1 judgment, entered after a jury
found him guilty of knowingly presenting to the Internal Revenue Service (IRS) a
false claim by filing a return for the 2002 tax year claiming a refund of $240,008.79,
in violation of 18 U.S.C. § 287 (Count 1); willfully attempting to evade income tax
due by failing to file income tax returns and attempting to conceal his income for
2002, 2003, 2004, and 2005, in violation of 26 U.S.C. § 7201 (Counts 2-5); and



      1
       The Honorable Linda R. Reade, Chief Judge, United States District Court for
the Northern District of Iowa.
attempting to obstruct the administration of internal revenue laws, in violation of 26
U.S.C. § 7212(a) (Count 6). For the reasons that follow, we affirm.

       We reject Mellor’s argument that the willful-blindness jury instruction
constructively amended Count 1 as it was charged in the indictment. See United
States v. Gill, 

, 849 (8th Cir. 2008) (jury instructions constructively
amend indictment if they so modify essential elements of charged offense that they
allow jury to convict defendant of offense other than one charged in indictment). The
jury instructions listed the elements of the false-claim offense, including that Mellor
must have known the claim was false, fictitious, or fraudulent; and the willful-
blindness instruction merely provided a means of inferring that knowledge. See
United States v. Aleman, 

, 1166 (8th Cir. 2008) (willful-blindness
instruction is proper if evidence supports inference that defendant was aware of high
probability of existence of fact in question and purposely contrived to avoid learning
facts in order to have defense), cert. denied, 

(2009).

       We further hold that the district court did not err in denying Mellor’s motion
to dismiss the indictment based on a change in the date he was alleged to have
committed the Count 1 offense, because we conclude that the modified date did not
constitute a constructive amendment of the indictment. The original and modified
dates--for each of which a range was given--were within two weeks of each other, and
both clearly referred to the same offense. See United States v. Harris, 

,
804-05 (8th Cir. 2003) (per curiam) (reversible constructive amendment occurs if
evidence used modified essential elements of offense; no error in district court’s
finding of guilt on or about date other than date charged in indictment, as date was
“reasonably near” date alleged).

      Finally, this court has previously rejected the contention that the IRS must issue
a tax assessment in order to meet its burden under section 7201 of proving the



                                          -2-
existence of a tax deficiency. See United States v. Gustafson, 

, 593 (8th
Cir. 2008).

      Accordingly, the judgment is affirmed.
