PART 1_INCOME TAXES--Table of Contents
 
Sec. 1.1091-1  Losses from wash sales of stock or securities.

    (a) A taxpayer cannot deduct any loss claimed to have been sustained 
from the sale or other disposition of stock or securities if, within a 
period beginning 30 days before the date of such sale or disposition and 
ending 30 days after such date (referred to in this section as the 61-
day period), he has acquired (by purchase or by an exchange upon which 
the entire amount of gain or loss was recognized by law), or has entered 
into a contract or option so to acquire, substantially identical stock 
or securities. However, this prohibition does not apply (1) in the case 
of a taxpayer, not a corporation, if the sale or other disposition of 
stock or securities is made in connection with the taxpayer's trade or 
business, or (2) in the case of a corporation, a dealer in stock or 
securities, if the sale or other disposition of stock or securities is 
made in the ordinary course of its business as such dealer.
    (b) Where more than one loss is claimed to have been sustained 
within the taxable year from the sale or other disposition of stock or 
securities, the provisions of this section shall be applied to the 
losses in the order in which the stock or securities the disposition of 
which resulted in the respective losses were disposed of (beginning with

[[Page 207]]

the earliest disposition). If the order of disposition of stock or 
securities disposed of at a loss on the same day cannot be determined, 
the stock or securities will be considered to have been disposed of in 
the order in which they were originally acquired (beginning with the 
earliest acquisition).
    (c) Where the amount of stock or securities acquired within the 61-
day period is less than the amount of stock or securities sold or 
otherwise disposed of, then the particular shares of stock or securities 
the loss from the sale or other disposition of which is not deductible 
shall be those with which the stock or securities acquired are matched 
in accordance with the following rule: The stock or securities acquired 
will be matched in accordance with the order of their acquisition 
(beginning with the earliest acquisition) with an equal number of the 
shares of stock or securities sold or otherwise disposed of.
    (d) Where the amount of stock or securities acquired within the 61-
day period is not less than the amount of stock or securities sold or 
otherwise disposed of, then the particular shares of stock or securities 
the acquisition of which resulted in the nondeductibility of the loss 
shall be those with which the stock or securities disposed of are 
matched in accordance with the following rule: The stock or securities 
sold or otherwise disposed of will be matched with an equal number of 
the shares of stock or securities acquired in accordance with the order 
of acquisition (beginning with the earliest acquisition) of the stock or 
securities acquired.
    (e) The acquisition of any share of stock or any security which 
results in the nondeductibility of a loss under the provisions of this 
section shall be disregarded in determining the deductibility of any 
other loss.
    (f) The word acquired as used in this section means acquired by 
purchase or by an exchange upon which the entire amount of gain or loss 
was recognized by law, and comprehends cases where the taxpayer has 
entered into a contract or option within the 61-day period to acquire by 
purchase or by such an exchange.
    (g) For purposes of determining under this section the 61-day period 
applicable to a short sale of stock or securities, the principles of 
paragraph (a) of Sec. 1.1233-1 for determining the consummation of a 
short sale shall generally apply except that the date of entering into 
the short sale shall be deemed to be the date of sale if, on the date of 
entering into the short sale, the taxpayer owns (or on or before such 
date has entered into a contract or option to acquire) stock or 
securities identical to those sold short and subsequently delivers such 
stock or securities to close the short sale.
    (h) The following examples illustrate the application of this 
section:

    Example 1. A, whose taxable year is the calendar year, on December 
1, 1954, purchased 100 shares of common stock in the M Company for 
$10,000 and on December 15, 1954, purchased 100 additional shares for 
$9,000. On January 3, 1955, he sold the 100 shares purchased on December 
1, 1954, for $9,000. Because of the provisions of section 1091, no loss 
from the sale is allowable as a deduction.
    Example 2. A, whose taxable year is the calendar year, on September 
21, 1954, purchased 100 shares of the common stock of the M Company for 
$5,000. On December 21, 1954, he purchased 50 shares of substantially 
identical stock for $2,750, and on December 27, 1954, he purchased 25 
additional shares of such stock for $1,125. On January 3, 1955, he sold 
for $4,000 the 100 shares purchased on September 21, 1954. There is an 
indicated loss of $1,000 on the sale of the 100 shares. Since, within 
the 61-day period, A purchased 75 shares of substantially identical 
stock, the loss on the sale of 75 of the shares ($3,750-$3,000, or $750) 
is not allowable as a deduction because of the provisions of section 
1091. The loss on the sale of the remaining 25 shares ($1,250-$1,000, or 
$250) is deductible subject to the limitations provided in sections 267 
and 1211. The basis of the 50 shares purchased December 21, 1954, the 
acquisition of which resulted in the nondeductibility of the loss ($500) 
sustained on 50 of the 100 shares sold on January 3, 1955, is $2,500 
(the cost of 50 of the shares sold on January 3, 1955) + $750 (the 
difference between the purchase price ($2,750) of the 50 shares acquired 
on December 21, 1954, and the selling price ($2,000) of 50 of the shares 
sold on January 3, 1955), or $3,250. Similarly, the basis of the 25 
shares purchased on December 27, 1954, the acquisition of which resulted 
in the nondeductibility of the loss ($250) sustained on 25 of the shares 
sold on January 3, 1955, is $1,250+$125, or $1,375. See Sec. 1.1091-2.

    Example 3. A, whose taxable year is the calendar year, on September 
15, 1954, purchased 100 shares of the stock of the M Company for $5,000. 
He sold these shares on February 1, 1956, for $4,000. On each of the 
four days from February 15, 1956, to February 18, 1956, inclusive, he 
purchased 50 shares of substantially identical stock for $2,000. There 
is an indicated loss of $1,000 from the sale of the 100 shares on 
February 1, 1956, but, since within the 61-day period A purchased not 
less than 100 shares of substantially identical stock, the loss is not 
deductible. The particular shares of stock the purchase of which 
resulted in the nondeductibility of the loss are the first 100 shares 
purchased within such period, that is, the 50 shares purchased on 
February 15, 1956, and the 50 shares purchased on February 16, 1956. In 
determining the period for which the 50 shares purchased on February 15, 
1956, and the 50 shares purchased on February 16, 1956, were held, there 
is to be included the period for which the 100 shares purchased on 
September 15, 1954, and sold on February 1, 1956, were held.
