Separate accounting apportionment shall be used if a corporate partner and partnership are not in a unitary relationship in which the apportioned income of the partnership and partner (excluding the partner's distributive share) are added together. When a corporation and a partnership are in a unitary relationship, then a blended or combined allocation factor should be used. This allocation factor is derived by adding the partnership and corporation allocation fractions together and applying the combined factor to the corporation's entire net income including its distributive share of the partnership's income (see N.J.A.C. 18:7-7.6(g)) .
