- 22 -22 percent of his vested interest in the partnership's salary reduction plan, which should have indicated to him that the distribution was not limited to the proceeds from the check he received and negotiated. Petitioner failed to make a bona fide and reasonable estimate of his tax liability when he filed Form 4868. See Crocker v. Commissioner, supra at 908. He underestimated his tax liability by two-thirds. Cf. Boatman v. Commissioner, T.C. Memo. 1995-356. His failure to obtain the necessary information to estimate properly his tax liability, as well as his failure to properly investigate the law regarding his tax issues, does not excuse the error in petitioner's estimate. Arnaiz v. Commissioner, supra. Petitioner's mistaken belief that he was entitled to a loss deduction for the value of accounts receivable and work in progress "left on the table" when he departed Heidelberg & Woodliff does not constitute reasonable cause for failure to make a proper estimate. See Mayhew v. Commissioner, T.C. Memo. 1994-310. Thus, we sustain respondent's voiding of the tax filing extensions obtained by petitioner. Because petitioner's reliance on the filing extensions constituted his sole defense to the section 6651 (a)(1) addition to tax, petitioner has not shown that his failure to timely file his 1991 tax return was due to reasonable cause and not willful neglect. See Crocker v. Commissioner, supra at 913. Accordingly, we hold that petitioner is liable for the section 6651(a)(1) 25-Page: Previous 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 Next
