Tax Controversy & Litigation Practice
Strategic transitions for tax controversy and litigation partners
Complex Regulatory Landscape • Cross-Border Expertise • Platform-First Approach
Tax controversy and litigation represents one of the most specialized and strategically vital practice areas in today's legal landscape. With enforcement priorities shifting globally, regulatory complexity accelerating, and stakes reaching unprecedented levels, firms are competing intensively for partners who can navigate high-stakes disputes, build institutional defense capabilities, and maintain trusted advisor relationships through complex proceedings.

What distinguishes our approach
- Deep Practice Intelligence: Real-time understanding of enforcement trends, regulatory shifts, and platform investments across markets

- Cross-Practice Integration: Identifying synergies with M&A, white-collar, and regulatory practices for comprehensive client service
Current Market Dynamics — Tax Controversy & Litigation
The tax controversy landscape has transformed dramatically. Global minimum tax frameworks, aggressive transfer pricing enforcement, digital economy taxation, and unprecedented information exchange between jurisdictions have created complexity that demands sophisticated counsel. Simultaneously, criminal tax enforcement has intensified, with prosecutors increasingly viewing tax violations as predicate offenses for broader investigations.
Key Market Indicators
85% increase in cross-border tax disputes since 2020
$47B in transfer pricing adjustments globally (2024)
Triple the number of criminal tax referrals to DOJ (vs. 2019)
60% of Fortune 500 companies facing simultaneous multi-jurisdiction audits
Platform Evolution & Investment Priorities
Pre-dispute planning: Controversy-conscious structuring and documentation
Administrative proceedings: IRS examinations, appeals, and competent authority
Litigation capabilities: Tax Court, District Court, Court of Federal Claims, and appellate practice
Criminal defense: Coordination with white-collar teams on tax fraud and evasion matters

Practice Segmentation — Where Opportunity Concentrates
Tax controversy practices span multiple specialized segments, each with distinct market dynamics and platform requirements.
Transfer Pricing Disputes
The most technically complex and economically significant segment. Firms seek partners who understand economic modeling, can manage expert witnesses effectively, navigate competent authority proceedings, and coordinate multi-jurisdiction defense strategies. Cross-border expertise and economist relationships are differentiators.
Criminal Tax Defense
Convergence with white-collar practice creates unique value. Partners bridging civil and criminal tax matters—particularly those with DOJ Tax Division or IRS Criminal Investigation experience—are highly sought. The ability to coordinate with FCPA, money laundering, and fraud defense teams multiplies platform value.
State and Local Tax (SALT) Controversies
Post-Wayfair complexity and aggressive state enforcement have elevated SALT controversy work. Partners with multistate audit defense experience, nexus and apportionment expertise, and relationships with state revenue departments see strong demand, particularly in technology and retail sectors.
International Tax Controversies
BEPS implementation, pillar two compliance, and treaty interpretation disputes require specialized expertise. Partners who can navigate OECD frameworks, manage mutual agreement procedures, handle withholding tax disputes, and coordinate global tax positions command premium opportunities.
Strategic Considerations for Tax Controversy Partners
Tax controversy practices present unique platform requirements and integration challenges that demand careful evaluation.
Platform Infrastructure Requirements
