IRS Watchdog Cites Resource Limits, Duplication in Partnership Audits

Why It Matters

The audit shortfalls risk widening the $42 billion partnership portion of the $696 billion tax gap, reducing federal revenue and undermining tax fairness.

Key Takeaways

• IRS audit duplication extended review timelines
• Funding cuts slashed partnership enforcement budget by $41.8B
• Examination rate for large partnerships fell below 0.1%
• AI risk models aim to improve partnership coverage
• High no‑change rates signal audit inefficiency

Pulse Analysis

Partnerships represent a growing slice of the U.S. tax base, yet the IRS’s ability to scrutinize them has eroded. The TIGTA review underscores how procedural inefficiencies—such as sequential agent reviews—inflate audit timelines without delivering results. Coupled with a dramatic reduction in the Inflation Reduction Act’s enforcement budget, the agency lost roughly one‑fifth of its pass‑through team, causing the examination rate for entities with $10 million-plus assets to plunge from 2.7% in 2011 to under 0.1% today. This contraction threatens to leave billions of dollars of partnership income under‑reported, feeding the broader $696 billion tax gap.

The funding shortfall is more than a line‑item issue; it reshapes the IRS’s risk‑based approach. With fewer auditors, the Large Business and International Division relies heavily on automated models to flag high‑risk returns. However, early data show a 92% no‑change outcome for the 36 closed examinations, suggesting the current selection criteria may be too broad or insufficiently targeted. High no‑change rates signal inefficiency, as taxpayer resources are expended without corresponding revenue gains, prompting calls for tighter model calibration and better integration of fiscal‑year considerations.

Looking ahead, the agency’s pivot to artificial intelligence and seasoned tax experts aims to close coverage gaps left by staffing cuts. By running risk models multiple times across fiscal years, the IRS hopes to capture returns that previously slipped through the cracks. Nonetheless, sustainable improvement will likely require congressional action to restore enforcement funding and address the systemic resource constraints that have hampered partnership compliance. Until then, the tax gap attributable to partnerships may continue to expand, pressuring policymakers to balance budgetary limits with revenue imperatives.
