Tax Court Holds that Deadline for Filing a BBA Partnership Petition Is Not Jurisdictional by Robert S. Horwitz

The BBA Partnership audit and litigation provisions were enacted in 2015 and became effective for tax years beginning on or after January 1, 2018. Internal Revenue Code (“IRC”) §6321(a) requires the IRS mail three notices to the partnership and the partnership representative:

1. Notice of the initiation of partnership proceedings, which advises the partnership and the partnership representative of the initiation of administrative proceedings at the partnership level of any partnership-related item;

2. Notice of proposed partnership adjustments (“NOPPA”) resulting from the proceedings, which sets out the proposed adjustments, any imputed underpayment the partnership will owe and gives the partnership an opportunity to make a modification request; and

3. Notice of final partnership adjustment (“FPA”), which sets out the final adjustments and any imputed underpayment and provides the partnership with the opportunity to petition the Tax Court, the Court of Federal Claims or a district court and to make any push-out election.
