M&A tax

Mergers and acquisitions are pivotal moments in a company’s growth journey. Yet, without careful tax planning, these transactions – especially cross-border deals – can introduce significant risk.

At Forvis Mazars, we help you navigate the complexities of M&A tax with precision, agility and global insight.
