All of the annual income, gains, losses, deductions or credits flow through the partnership to the unitholders on a per unit basis. The unitholders are required to report their allocated share of these amounts on their income tax returns whether or not any cash distributions are paid by the partnership.• Cash distributions paid by a partnership to a unitholder are generally not taxable, unless the amount of any cash distributed is in excess of the unitholder’s adjusted basis in his partnership interest.• Generally in late February, Enterprise provides each unitholder a Schedule K-1 tax package that includes each unitholder’s allocated share of reportable partnership items and other partnership information necessary to complete their income tax returns. The K-1 provides a unitholder the required tax information for their ownership interest in the partnership, just as a Form 1099-DIV does for a stockholder’s ownership interest in a corporation.
