- 11 - chosen tax treatment was more likely than not the proper one. Petitioner bears the burden of establishing that respondent's determination was erroneous. Cluck v. Commissioner, 105 T.C. 324, 340 (1995). Respondent determined that the understatement was substantial. Petitioner does not dispute this point. Thus, petitioner must establish that the understatement should be reduced if he is to avoid imposition of the addition to tax for substantial understatement. Petitioner's sole argument is that he reasonably relied on the agreement, which he implies constitutes substantial authority. Petitioner, however, has not cited, nor have we found, any authority that suggests that this agreement constitutes substantial authority. Petitioner was not reasonable in relying on the agreement for purposes of the addition to tax for negligence, nor has he established that he reasonably believed that taking the deductions relating to his 1983 tax shelter investment was more likely than not correct. Consequently, we conclude that petitioner is liable for the addition to tax for substantial understatement. We have considered petitioner's other arguments and found them to be without merit. To reflect the foregoing, Decision will be entered for respondent.Page: Previous 1 2 3 4 5 6 7 8 9 10 11
