Moreover, they have failed to provide even the minimal substantiation that would permit us to estimate the allowable deduction under Cohan v. Commissioner, 39 F.2d 540, 543- 544 (2d Cir. 1930). Even under Cohan, there must be sufficient evidence in the record to provide a basis upon which an estimate may be made. Vanicek v. Commissioner, 85 T.C. 731, 742-743 (1985). Here, there is none. By failing to provide any substantiation that would corroborate Dr. Derby's somewhat uncertain testimony, the Derbys have failed to sustain their burden of proof under Rule 142(a) as to either the existence or deductibility of the alleged expenditures. Moreover, assuming arguendo that Dr. Derby actually incurred the alleged expenditures and that they were of a type that would be currently deductible by the corporation, the evidence does not establish whether Dr. Derby incurred them on behalf of the corporation with an expectation of reimbursement or intended that they constitute a capital contribution to the corporation. Dr. Derby's oral testimony is consistent with either approach.40 The Derbys' failure to prove the existence of a constructive loan provides an additional basis for respondent's $3,665 adjustment. 40 Although Dr. Derby testified that he was reimbursed by the corporation when the corporation was dissolved, that "reimbursement" distribution is consistent with either a debt repayment or a final cash distribution in connection with the dissolution.Page: Previous 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 NextLast modified: March 27, 2008
