IRS Audit Defense & Tax Controversy
Protecting Enterprise Value
Strategic Advocacy in an Era of Increased Federal Scrutiny
Federal tax audits are no longer routine. With the IRS receiving significant funding for increased enforcement—particularly targeting large partnerships, high-net-worth individuals, and mid-market corporations—the stakes of a federal inquiry have never been higher. A tax controversy is not just a financial risk; it is a distraction that can stall transactions, trigger debt covenant issues, and drain executive resources.
We provide the technical rigor to level the playing field. At Calvetti Ferguson, we act as your primary advocate and buffer against federal scrutiny. Our tax controversy team combines deep technical knowledge of the Internal Revenue Code with a strategic understanding of IRS procedures. We don’t just “respond” to inquiries; we manage the narrative, substantiating your positions with institutional-grade documentation and negotiating from a position of technical strength.
A Multidimensional Approach to Tax Controversy
We provide a comprehensive defense framework designed to narrow the scope of inquiries and achieve the most favorable resolution possible.
Technical Audit Representation
We take full control of the audit process, allowing your team to focus on core operations.

-
Managing Information Document Requests (IDRs): We act as the sole point of contact for IRS agents, ensuring that all responses are technically accurate and strategically framed to prevent unnecessary scope expansion.

Substantiation & Technical Memoranda: For complex issues like R&D credits, international transfer pricing, or executive compensation, we provide the formal technical narratives required to support your positions under heavy scrutiny.
-
On-Site Exam Management: We host the audit at our offices whenever possible, minimizing the footprint of the IRS within your daily business environment.

Dispute Resolution & Appeals
If an agreement cannot be reached at the examination level, we provide the advocacy needed to escalate and resolve the matter.

-
-
IRS Appeals Representation: We represent your interests before the IRS Independent Office of Appeals, utilizing their mandate for “fair and impartial” resolution to settle disputes without the need for costly litigation.
-
Penalty Abatement & Interest Mitigation: We utilize “reasonable cause” arguments and specialized tax statutes to aggressively pursue the waiver of penalties, which can often represent a significant portion of a total assessment.
-
Statute of Limitations Management: We strategically manage the expiration of assessment periods to protect your rights and provide maximum leverage during negotiations.
-
-
Specialized Controversy Areas
We tailor our defense strategies to the specific technical complexities that trigger federal interest:
-
-
-
Partnership & BBA Audits: Navigating the complex rules of the Bipartisan Budget Act (BBA) for PE-backed and large-scale partnership structures.
-
Employee Retention Credit (ERC) Defense: Providing the rigorous documentation and “audit-ready” files required to defend ERC claims against the current wave of IRS examinations.
-
International & Cross-Border Disputes: Defending transfer pricing methodologies, FBAR compliance, and foreign tax credit allocations for global enterprises.
-
Section 174 & R&D Credit Exams: Substantiating the technical “process of experimentation” and qualitative narratives for high-value tax incentive claims.
