- 24 - computer records in October 1993 provided no evidence of fraud because an assessment occurs on the date an authorized official signs a summary record of assessment containing the taxpayer’s assessment rather than the date the assessment is posted to the IRS computerized record system. * * * Indeed, Mr. Davis neglects even to discuss Ms. Osborn or her “cycle post date” theory in his written responses to our orders to show cause, which suggests to us that he no longer attaches any value to her testimony or theory. See Nicklaus v. Commissioner, 117 T.C. 117, 120 n.4 (2001) (concluding that taxpayers abandoned arguments and contentions asserted prior to the filing of their brief where they failed to advance those arguments and contentions on brief). We see no merit in his affirmative defense. Mr. Davis’s inability to show the merit of any averment, claim, or argument advanced by him leads us to the conclusion that he initiated and has maintained these proceedings primarily for delay, and we so find. Indeed, he was sanctioned for just such conduct (and fined $25,000) in the proceeding that he initiated to contest respondent’s determination of his underlying tax liabilities for 1997 and 1998. A taxpayer’s good faith reliance on the advice of counsel is not a defense to the imposition of a penalty under section 6673(a)(1)(B). See Branch v. IRS, 846 F.2d 36, 37 (8th Cir. 1988). Nor need we excuse a taxpayer’s failure to review pleadings and other documents filed on his behalf.
