General rule.
(1) Section 705 and this section provide rules for determining the adjusted basis of a partner's interest in a partnership. A partner is required to determine the adjusted basis of his interest in a partnership only when necessary for the determination of his tax liability or that of any other person. The determination of the adjusted basis of a partnership interest is ordinarily made as of the end of a partnership taxable year. Thus, for example, such year-end determination is necessary in ascertaining the extent to which a partner's distributive share of partnership losses may be allowed. See section 704(d). However, where there has been a sale or exchange of all or a part of a partnership interest or a liquidation of a partner's entire interest in a partnership, the adjusted basis of the partner's interest should be determined as of the date of sale or exchange or liquidation. The adjusted basis of a partner's interest in a partnership is determined without regard to any amount shown in the partnership books as the partner's “capital”, “equity”, or similar account. For example, A contributes property with an adjusted basis to him of $400 (and a value of $1,000) to a partnership. B contributes $1,000 cash. While under their agreement each may have a “capital account” in the partnership of $1,000, the adjusted basis of A's interest is only $400 and B's interest $1,000.
(2) The original basis of a partner's interest in a partnership shall be determined under section 722 (relating to contributions to a partnership) or section 742 (relating to transfers of partnership interests). Such basis shall be increased under section 722 by any further contributions to the partnership and by the sum of the partner's distributive share for the taxable year and prior taxable years of:
(i) Taxable income of the partnership as determined under section 703(a),
(ii) Tax-exempt receipts of the partnership, and
(iii) The excess of the deductions for depletion over the basis of the depletable property, unless the property is an oil or gas property the basis of which has been allocated to partners under section 613A(c)(7)(D).
(3) The basis shall be decreased (but not below zero) by distributions from the partnership as provided in section 733 and by the sum of the partner's distributive share for the taxable year and prior taxable years of:
(i) Partnership losses (including capital losses), and
(ii) Partnership expenditures which are not deductible in computing partnership taxable income or loss and which are not capital expenditures.
(4) The basis shall be decreased (but not below zero) by the amount of the partner's deduction for depletion allowable under section 611 for any partnership oil and gas property to the extent the deduction does not exceed the proportionate share of the adjusted basis of the property allocated to the partner under section 613A(c)(7)(D).
(5) The basis shall be adjusted (but not below zero) to reflect any gain or loss to the partner resulting from a disposition by the partnership of a domestic oil or gas property after December 31, 1974.
(6) For the effect of liabilities in determining the amount of contributions made by a partner to a partnership or the amount of distributions made by a partnership to a partner, see section 752 and § 1.752–1, relating to the treatment of certain liabilities. In determining the basis of a partnership interest on the effective date of subchapter K, chapter 1 of the Code, or any of the sections thereof, the partner's share of partnership liabilities on that date shall be included.
(7) For basis adjustments necessary to coordinate sections 705 and 1032 in certain situations in which a partnership disposes of stock or any position in stock to which section 1032 applies of a corporation that holds a direct or indirect interest in the partnership, see § 1.705–2.
(8) For basis adjustments necessary to coordinate sections 705 and 358(h), see § 1.358–7(b). For certain basis adjustments with respect to a § 1.752–7 liability assumed by a partnership from a partner, see § 1.752–7.
(9) For basis adjustments necessary to coordinate sections 705 and 362(e)(2), see § 1.362–4(e)(1).
