Reporting federal audit changes for partnerships under the Bipartisan Budget Act of 2015 (BBA)

The federal Bipartisan Budget Act of 2015 (BBA), also referred to as the centralized partnership audit regime, enacted sweeping changes to the federal audit and tax collection procedures for partnerships. The BBA is generally effective for tax years beginning January 2018. 

New York State passed legislation in 2025 requiring partnerships and partners who are impacted by the BBA to report those changes to New York State (Tax Law § 659-a).
