On Sept. 10, 2021, Senate Finance Committee Chairman Ron Wyden released a discussion draft and legislative text that would dramatically change existing partnership tax rules. While none of the proposed changes were included in the Infrastructure Investment and Jobs Act enacted on Nov. 15, 2021, or the version of the Build Back Better Act passed by the House on Nov. 19, 2021, the proposals have caused partnerships and their advisers to take notice. Wyden’s proposals address a number of perceived abuses related to the optionality and ambiguity that are prevalent in the current partnership tax rules.
