The burden that respondent bears in proving fraud under section 6501(c)(1) is the same burden that he bears in establishing fraud for purposes of the section 6663(a) penalty. Ruidoso Racing Association, Inc. v. Commissioner, 476 F.2d 502, 507 (10th Cir. 1973), affg. in part and remanding in part T.C. Memo. 1971-194; DeBrouse v. Commissioner, T.C. Memo. 1988-119, affd. 878 F.2d 379 (4th Cir. 1989). Since respondent has met his burden for purposes of section 6501(c)(1), we hold that respondent has established that a portion of petitioners' underpayment is due to fraud for purposes of section 6663(a). We further hold that petitioners have not presented credible evidence that any portion of their underpayment was not due to fraud. Accordingly, we sustain respondent's determination for additions to tax and penalties imposed by sections 6653(b) and 6663(a). III. Additions to Tax Under Sec. 6651 Respondent determined that petitioner AJF was liable for the additions to tax imposed by section 6651(a). Section 6651(a) imposes an addition to tax for failing to file a timely income tax return, unless such failure to file is due to reasonable cause and not due to willful neglect. The addition to tax is 5 percent of the amount required to be reported on the return for each month or fraction thereof during which such failure to filePage: Previous 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 Next
