- 10 - he is entitled to the deductions claimed. Rule 142(a)(1); INDOPCO, Inc. v. Commissioner, 503 U.S. 79, 84 (1992); New Colonial Ice Co. v. Helvering, 292 U.S. 435, 440 (1934). In addition, a taxpayer must keep sufficient records to substantiate any deductions claimed. Sec. 6001; New Colonial Ice. Co. v. Helvering, supra at 440. Section 7491(a) does not apply in this case because petitioner did not introduce credible evidence that he is entitled to the deduction he seeks. In general, under section 151(a) and (c), a taxpayer is allowed a dependency exemption deduction for each dependent. Sec. 152(a)(1). The definition of a “dependent” provided by section 152(a) includes a child of the taxpayer over half of whose support for the year was provided by the taxpayer. See sec. 1.152-1(a), Income Tax Regs. In the case of a child of divorced parents, the child generally is treated as receiving over half his support from the parent having custody for the greater portion of the year. Sec. 152(e)(1) and (2). In order to satisfy the support test of section 152(a) so as to be entitled to a dependency exemption deduction, the taxpayer must prove the amount of total support the child received during the year and establish that the support that the taxpayer provided exceeds half the total.
