Harlan F. Stone,
White v. United States (305 U.S. 281…
“ Section 21, 26 U.S.C.A. § 21, declares that net income means gross income computed under § 22, less the deductions allowed by § 23. As already noted, § 23 (e) , (g) , providing for deductions of losses on sales or exchanges of property, is restricted in its operation by the provisions of § 101. Otherwise, § 101 would have no application to deductible losses. These general provisions thus incorporate by reference those of § 101 and give to them controlling effect in the computation of the tax in cases of capital gains or losses upon the sale or exchange of capital assets. ”
