I've got a new client. He has LP Units in a large partnership. He is an employee in this partnership as well. His ownership stake is less than 1%.
He has purchased some of these Units with cash if they have a funding event. He also gets options to buy and has exercised these options to buy additional Units.
In 2019, there was a "Buyback" and the Partnership allowed Unitholders to be bought out, and/or roll the old LP Units into a new Unit with new terms. He did both: took some cash off the table, and then rolled some of his units into the new A-Units.
I need a primer on LP units taxable events and basis for these transactions. Does the Buyback amount to a redemption and it is thus possibly not a taxable event?
Thank you in advance.
