Burden of Proof Generally, the Commissioner’s determinations in a notice of deficiency are presumed correct, and the taxpayer has the burden to prove that the determinations are in error. Rule 142(a); Welch v. Helvering, 290 U.S. 111, 115 (1933). But the burden of proof is shifted to the Commissioner when he seeks to raise a “new matter”, which is defined as a new assertion that does not simply narrow the issue raised in the deficiency notice and either alters the amount of the original deficiency or requires the presentation of different evidence. See Rule 142(a); Estate of Falese v. Commissioner, 58 T.C. 895, 897-899 (1972); McSpadden v. Commissioner, 50 T.C. 478, 491-492 (1968); Papineau v. Commissioner, 28 T.C. 54, 57 (1957); Tauber v. Commissioner, 24 T.C. 179, 185 (1955). Where the new assertion merely clarifies or develops the original determination’s basis without increasing the deficiency amount, the burden of proof does not shift to the Commissioner.
