Partnership Audit Rules (BBA)

The Partnership Audit Rules under the Bipartisan Budget Act (BBA) created a centralized federal audit regime that generally allows the partnership entity, rather than individual partners, to be assessed for adjustments and tax liabilities for audited tax years. In commercial real estate partnerships, this shifts audit exposure dynamics and can result in the partnership or current partners bearing tax costs arising from prior years. Lenders need to understand these rules because post-audit assessments can create cash calls, reduce distributions, and interfere with debt service if funds must be remitted to satisfy audit adjustments.

Lenders should review partnership agreements for BBA-related provisions such as tax matters partner designation, opt-out elections where available at the partner level, and indemnity clauses allocating audit risk among partners. Underwriting should include scenarios where audit adjustments trigger partnership-level payments or changes to tax distributions, and loan documents may require reserves or notification covenants. Sponsors should disclose how they manage BBA risk and whether insurance or contractual protections exist to prevent audit liabilities from cascading to the lender or disrupting the capital structure.

BBA audit rules can produce unanticipated partnership-level tax liabilities that reduce available cash and impair a borrower’s ability to meet debt service, particularly when the assessed tax relates to years prior to a sponsor’s acquisition. For lenders, the centralized assessment process increases the importance of contractual protections and transparency around tax positions. Properly addressing BBA exposure in diligence and loan documentation mitigates the risk that partnership audit outcomes will create liquidity pressure, breach covenants, or require lender intervention to preserve collateral value.
