N.Y. Comp. Codes R. & Regs. tit. 20, § 3-13.3
(2) A taxpayer's proportionate part of the partnership's assets and liabilities and activities is determined in accordance with the taxpayer's capital interest in the partnership. If using a taxpayer's capital interest in a partnership to determine the taxpayer's share of partnership items constituting business capital and investment capital does not properly reflect the taxpayer's share of partnership items constituting business income and investment income, then the taxpayer's proportionate part of the partnership's assets and liabilities and activities is determined using the percentage resulting from the manner in which the partners divide the partnership's profits in a profit year and losses in a loss year.
(ii) The determination of whether a principal purpose of an allocation of an item, amount or activity is the avoidance or evasion of any tax imposed on the taxpayer, or the combined group of which the taxpayer is a member, by New York State or any of its political subdivisions depends on all the surrounding facts and circumstances. Among the relevant circumstances to be considered are the following:
(e) the overall tax consequences of the allocation.
(b) Entire net income and minimum taxable income bases.
Example:
Corporations A and B are partners in partnership P. A will perform services for a 40 percent interest in the profits and losses of the partnership and B will contribute $1,000 for a 60 percent interest in the profits and losses of the partnership. B's capital interest is 100 percent and A's capital interest is zero. P's only asset is $1,000 of stock. The stock pays dividends of $30 during the taxable year. A's distributive share of the dividends is $12 and B's distributive share is $18. Based on capital interests, A's proportionate part of P's stock is zero ($1,000 × 0 percent) and B's proportionate part of P's stock is $1,000 ($1,000 × 100 percent). In this case, using capital interests does not properly reflect A's share of P's stock (which constitutes investment capital). This is because A receives 40 percent of P's dividends (which constitutes investment income) and using capital interests attributes none of P's stock (which constitutes investment capital) to A. Likewise, B receives 60 percent of P's dividends and using capital interests attributes all of P's stock to B. In this case, both A and B must determine their proportionate part of P's assets and liabilities in accordance with their profits and loss interest (40 percent and 60 percent, respectively) in P.

(2) A taxpayer may use the reduced rate of tax for a small business taxpayer provided in section 210.1(a) of the Tax Law if the taxpayer qualifies as a small business taxpayer as defined in section 210.1(f) of the Tax Law. For purposes of the entire net income component of such section 210.1(f), it shall take into account its distributive share of the partnership items described in paragraph (1) of this subdivision that are included in determining its entire net income.
(c) Capital base.
(2) For purposes of the exemption from the tax measured by the capital base for a small business concern, the taxpayer must qualify as a small business concern as defined in section 210(1-c) of the Tax Law. In determining whether the taxpayer qualifies, it shall take into account its proportionate part of partnership amounts described in paragraph (d) of such subdivision.
(d) Fixed dollar minimum.
(1) A taxpayer's distributive share or proportionate part, as the case may be, of partnership amounts of the items described in section 3-5.1(b) of this Part shall be taken into account in determining the tax measured by the fixed dollar minimum. (See Subpart 3-5 of this Part and section 210.1[d] of the Tax Law for information relating to the tax measured by the fixed dollar minimum.)
(e) Subsidiary capital base.
