EY Global Synergy BSM's international tax practice and EY's global network create a strong cross-sell opportunity to deliver integrated tax and legal services to large multinational clients, including FATCA compliance, cross-border structuring, and transfer pricing, across the US, UK, and Europe.

Global Client Base BSM serves some of the world’s largest industrials, financial institutions, and foreign governments. EY can leverage these relationships to expand advisory, litigation support, and regulatory services, including government-level tax policy counsel.

Cross Border Demand The firm's focus areas—cross-border financial structures, FATCA, rulings, and litigation—signal a sustained demand for international tax guidance. EY's global platform and resources could scale these services and add risk management, transfer pricing, and dispute resolution capabilities.

Geographic Growth With offices in Washington DC and London, there is a natural path to expand to other key financial centers using EY's footprint and cross-border teams.

Digital Enablement Their tech stack suggests basic web infrastructure; EY can introduce enterprise-grade tax tech, workflow automation, data analytics, and secure collaboration tools to enhance client delivery for multinational engagements.
