Title 26: Internal Revenue
PART 1—INCOME TAXES (CONTINUED)


§1.172-6   Illustration of net operating loss carrybacks and carryovers.

The application of §1.172-4 may be illustrated by the following example:

(a) Facts. The books of the taxpayer, whose return is made on the basis of the calendar year, reveal the following facts:

Taxable yearTaxable incomeNet operating loss
