Tax Information

TC PipeLines, LP (the Partnership) is a publicly traded limited partnership which, as an entity, is generally not subject to federal or state income tax. Instead, partners are required to report their allocable share of the Partnership's items of taxable income, gain, deduction or loss in their individual income tax returns as though each partner had incurred such items directly.

The Partnership determines taxable income annually and allocates it to the unitholders in accordance with the Partnership agreement. Unitholders are required to include their share of the Partnership's taxable income in their income for tax purposes and add the amount to the tax basis of their units. The amount 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 limited partner's units.

The Tax Cuts and Jobs Act of 2017 created a new deduction (Section 199A) to effectively reduce the tax rate for certain taxpayers with respect to specific types of business income. The Partnership generates income that is eligible for the new deduction and the corresponding lower effective tax rate. For individuals, trusts and estates holding units in the Partnership, the amount reported on Line 20AD (Section 199A PTP Income) is crucial to claiming the new deduction. Consult your tax advisor concerning the impact of the tax law changes to you.
