K-1 Tax Information

The K-1 packages for the common units are available online at the links below. The information reported to you on the Schedule K-1 is subject to change. If the Tax Relief for American Families and Workers Act of 2024 (H.R. 7024), which passed the House of Representatives and is awaiting action in the Senate, were to become law, we could be forced to make changes to our tax reporting for 2023. Such changes may affect the information reported to you on Schedule K-1.

Please note that receipt of a tax package is not proof of ownership in NuStar Energy L.P.

For assistance with your NS K-1s, you may call K-1 Tax Package Support toll free at (800) 310-6595, between 8:00am and 5:00pm, CST.

The recently proposed legislation does not impact NuStar's Preferred units; therefore, the K-1 packages for the Preferred A, B and C are available online at the links below.
