IN recent weeks the Treasury Department has issued nearly 300 pages of new regulations on the new partnership audit and collection rules, commonly known and referred to as the centralized partnership audit regime or “BBA,” for short.  More regulations are expected to follow in ensuing months. These new regulations augment more than 200 pages of existing final and proposed BBA regulations.

The BBA is the new method that the IRS will use to audit and collect taxes from entities taxed as partnerships (in many cases, limited liability companies or “LLCs” for short).  The BBA generally becomes effective for tax years starting on or after January 1, 2018.

Under prior law, each member for the audited year was individually required to pay his or her share of taxes if the IRS found unreported income.  Moreover, most members could challenge the IRS’ determinations in US Tax Court or other venue. Under the new BBA procedures, however, the general rule is that the LLC will bear the tax bill (with some exceptions), and only a single individual or company designated as the “partnership representative” can contest the IRS’ determinations in court.  Unlike prior law, this may result in new partners or LLC members directly or indirectly bearing the tax bill of the former owners, with no legal recourse to challenge the IRS. Hence the BBA may result in state court lawsuits among members for back tax payments.

Note that in many instances it can take the Treasury years to issue new regulations after a new tax law is enacted, but here regulations are being issued at breakneck speed.  Under the proposed Treasury regulations issued last June, the IRS noted the need for the BBA as a means of beefing up IRS tax audits and collections on partnership entities. Indeed, the heavy BBA regulatory activity over the last year or so likely means that the IRS is gearing up for increased audits of LLCs and other partnership entities in 2019 and beyond.
