IRS Publication 5388 – In the complex world of tax regulations, partnerships face unique challenges when it comes to audits and adjustments. IRS Publication 5388, titled “Bipartisan Budget Act (BBA) Roadmap for Taxpayers,” serves as a crucial guide for navigating these processes. Released in July 2021, this document outlines the centralized partnership audit regime established under the Bipartisan Budget Act of 2015. It applies to tax years beginning on or after January 1, 2018, shifting the focus from individual partner audits to partnership-level assessments. This article breaks down the key elements of Publication 5388, helping taxpayers, partnership representatives, and tax professionals understand the audit roadmap, timeframes, and options for compliance.
What Is the Bipartisan Budget Act (BBA) and Why Does It Matter?
The Bipartisan Budget Act (BBA) revolutionized how the IRS audits partnerships by centralizing the process at the partnership level rather than targeting individual partners. Prior to BBA, audits could lead to separate adjustments for each partner, creating administrative burdens. Under BBA, the partnership itself is responsible for any imputed underpayments (IU), unless it elects to “push out” the adjustments to its partners.
Publication 5388 acts as a visual and procedural roadmap, detailing the steps from filing a return to post-audit resolutions. It’s particularly valuable for partnerships that don’t qualify to elect out of BBA rules—such as those with more than 100 partners or complex ownership structures. By following this guidance, taxpayers can avoid penalties, streamline appeals, and make informed decisions on whether to pay adjustments at the partnership level or shift them to partners.
Key Components of the BBA Roadmap in IRS Publication 5388
The publication is structured around three main phases: Filing/Audit Selection, Audit Process, and Post Audit. It includes flowcharts illustrating the sequence of events, IRS notifications, and taxpayer actions. These diagrams help visualize the centralized process, emphasizing timeframes like the 30-day window after audit selection notices and the 270-day period for modification requests.
Filing and Audit Selection Phase
Everything starts with the original tax return. For tax years beginning January 1, 2018, and onward, partnerships are automatically under BBA unless they meet specific criteria (e.g., all partners are individuals, estates, C corporations, or certain foreign entities) and elect out on a timely filed return. A key requirement is designating a Partnership Representative (PR) on the return—this individual has sole authority to act on behalf of the partnership during audits.
If the return is selected for examination, the IRS issues Letter 2205D as the notice of selection. The exam team verifies the PR, and an Administrative Adjustment Request (AAR) can be filed before the Notice of Administrative Proceeding (NAP) to proactively address issues.
Audit Process Phase
Once selected, the audit follows familiar examination steps but under BBA procedures. The NAP (Letter 5893 or 5893A) must be issued at least 30 days after Letter 2205D. Preliminary changes are communicated via Letter 5895 with Form 14791/886A, followed by a 30-day letter (Letter 5891).
The cornerstone of this phase is the Notice of Proposed Partnership Adjustment (NOPPA), issued via Letter 5892/5892A with Form 14792/886A. This determines the final IU and starts a 270-day window for modification requests, where partnerships can submit evidence to reduce the underpayment (e.g., amended returns from partners or rate adjustments). Appeals are possible, but an issue can’t be appealed more than once.
Post-Audit Phase and Closing Procedures
After modifications, the IRS issues a modification determination package (Letter 5975 with Form 15027). The process culminates in the Notice of Final Partnership Adjustment (FPA) via Letter 5933/5933A with Form 15027/886A. This triggers critical deadlines: 45 days to elect pushout and 90 days to petition a court.
In the pushout option, the partnership provides statements to partners and the IRS detailing adjustments, relieving the partnership of IU liability. Alternatively, the partnership can pay the IU directly. Post-audit forms require mandatory electronic filing after registration on the IRS website.
Important Terms and Definitions from Publication 5388
To fully grasp the roadmap, familiarize yourself with these terms:
- Partnership Representative (PR): The designated authority for all BBA interactions.
- Imputed Underpayment (IU): The calculated tax deficiency at the partnership level.
- Notice of Administrative Proceeding (NAP): Formal start of the audit, with a 30-day lead time.
- Notice of Proposed Partnership Adjustment (NOPPA): Proposes adjustments and opens modification period.
- Final Partnership Adjustment (FPA): Final IRS determination, starting appeal and pushout windows.
- Pushout Election: Shifts adjustment responsibility to partners via statements.
Practical Guidance for Taxpayers Navigating BBA Audits
Taxpayers should start by ensuring their return designates a reliable PR and considers electing out if eligible. During audits, respond promptly to notices—missing the 270-day modification window could lock in a higher IU. Gather supporting documents early for modifications, and weigh the pros and cons of pushout: it reduces partnership liability but shifts the burden to partners.
