The Partnership determines taxable income annually and allocates it to the partners on Schedule K-1 in accordance with the Partnership agreement. Partners are required to include their share of the Partnership's taxable income on their tax return and add the amount to the tax basis of their units. The amount of taxable income allocated may exceed or be less than the amount of cash distributed in the year. Generally, cash distributions are considered a return of capital and reduce the tax basis of a partner's units. Please note, the Partnership generates income that is eligible for the Section 199A 20% tax deduction.

TC PipeLines, LP is a publicly traded limited partnership consisting of one general partner and many limited partners (the investing public or “unitholders”). Therefore, all income and expenses flow through to the partners to be reported on their individual tax returns. Annually, the Partnership mails each partner a tax package that includes a Schedule K-1, a State Schedule, an Ownership Schedule, a Sales Schedule and other information relevant to their tax reporting obligations. Also, the Partnership is required to file a Form 1065 with the IRS which includes a Schedule K-1 for each partner reporting their respective share of taxable income and other IRS prescribed items. Consult your personal tax advisor for proper reporting of your tax package amounts.
