Sec. 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:
------------------------------------------------------------------------
Net
Taxable year Taxable operating
income loss
------------------------------------------------------------------------
1954.............................................. $15,000 .........
1955.............................................. 30,000 .........
1956.............................................. ......... ($75,000)
1957.............................................. 20,000 .........
1958.............................................. ......... (150,000)
1959.............................................. 30,000 .........
1960.............................................. 35,000 .........
1961.............................................. 75,000 .........
1962.............................................. 17,000 .........
1963.............................................. 53,000 .........
------------------------------------------------------------------------
The taxable income thus shown is computed without any net operating loss deduction. The assumption is also made that none of the other modifications prescribed in §1.172–5 apply. There are no net operating losses for 1950, 1951, 1952, 1953, 1964, 1965, or 1966.
(b) Loss sustained in 1956. The portions of the $75,000 net operating loss for 1956 which shall be used as carrybacks to 1954 and 1955 and as carryovers to 1957, 1958, 1959, 1960, and 1961 are computed as follows:
