Example: A, a single individual, computes a net operating loss of $15,000 for 1980 in accordance with the rules of § 1.172-3 , relating to net operating loss in case of a taxpayer other than a corporation. Included within A's computation of this net operating loss is a deduction arising under section 1244 for a loss on small business stock. A had no taxable income in 1977, 1978, or 1979. Assume that A can carry over the entire $15,000 loss under the rules of section 172. In 1981 A has gross income of $75,000 and again sustains a loss on section 1244 stock. The amount of A's 1981 loss on section 1244 stock is $50,000. A may deduct the full $50,000 as an ordinary loss under section 1244 and the full $15,000 as a net operating loss carryover in 1981.
