(4) The provisions of this paragraph may be illustrated by the following examples:
Example 1. At the end of the partnership taxable year 1955, partnership AB has a loss of $20,000. Partner A's distributive share of this loss is $10,000. At the end of such year, A's adjusted basis for his interest in the partnership (not taking into account his distributive share of the loss) is $6,000. Under section 704(d), A's distributive share of partnership loss is allowed to him (in his taxable year within or with which the partnership taxable year ends) only to the extent of his adjusted basis of $6,000. The $6,000 loss allowed for 1955 decreases the adjusted basis of A's interest to zero. Assume that, at the end of partnership taxable year 1956, A's share of partnership income has increased the adjusted basis of A's interest in the partnership to $3,000 (not taking into account the $4,000 loss disallowed in 1955). Of the $4,000 loss disallowed for the partnership taxable year 1955, $3,000 is allowed A for the partnership taxable year 1956, thus again decreasing the adjusted basis of his interest to zero. If, at the end of partnership taxable year 1957, A has an adjusted basis of his interest of at least $1,000 (not taking into account the disallowed loss of $1,000), he will be allowed the $1,000 loss previously disallowed.
Example 2. At the end of partnership taxable year 1955, partnership CD has a loss of $20,000. Partner C's distributive share of this loss is $10,000. The adjusted basis of his interest in the partnership (not taking into account his distributive share of such loss) is $6,000. Therefore, $4,000 of the loss is disallowed. At the end of partnership taxable year 1956, the partnership has no taxable income or loss, but owes $8,000 to a bank for money borrowed. Since C's share of this liability is $4,000, the basis of his partnership interest is increased from zero to $4,000. (See sections 752 and 722, and §§1.752-1 and 1.722-1.) C is allowed the $4,000 loss, disallowed for the preceding year under section 704(d), for his taxable year within or with which partnership taxable year 1956 ends.
Example 3. At the end of partnership taxable year 1955, partner C has the following distributive share of partnership items described in section 702(a): Long-term capital loss, $4,000; short-term capital loss, $2,000; income as described in section 702(a)(9), $4,000. Partner C's adjusted basis for his partnership interest at the end of 1955, before adjustment for any of the above items, is $1,000. As adjusted under section 705(a)(1)(A), C's basis is increased from $1,000 to $5,000 at the end of the year. C's total distributive share of partnership loss is $6,000. Since without regard to losses, C has a basis of only $5,000, C is allowed only $5,000/$6,000 of each loss, that is, $3,333 of his long-term capital loss, and $1,667 of his short-term capital loss. C must carry forward to succeeding taxable years $667 as a long-term capital loss and $333 as a short-term capital loss.
