M&A strategy: Tackling tax head-on for transaction readiness
Tax as a strategic value driver
In today’s dynamic M&A market, transaction readiness often requires more than just speed; it typically calls for broad-based planning that brings tax departments in early for strategic conversations and cross-functional alignment across finance, legal, operations, and deal teams. Deloitte’s 2026 M&A Tax Survey Report shows that organizations are increasingly treating the involvement of tax teams as a strategic value driver that can help identify and prioritize potential opportunities, inform structuring, streamline diligence, and mitigate costly surprises across the deal life cycle.
Whether companies are pursuing an acquisition, divestiture, restructuring, or integration, tax can play a critical role from the start through close. Explore the M&A tax considerations from our 2026 survey and see how early tax involvement can help organizations protect value, sharpen deal economics, and support more confident transaction outcomes.
Top takeaways
- Tax as part of the M&A strategy. A well-planned M&A strategy often includes tax in the early phases of deal strategy, reflecting a broader market shift toward more value-driven transaction planning.
- Tax can do more than protect value—it can create it. Some organizations are using tax to influence strategy, strengthen deal economics, and sharpen decision-making across the transaction.
- Tax as an end-to-end differentiator. Opportunity may be unlocked when tax insights are embedded into execution across close, integration, and the future operating model.
Buy-side
Before acquiring a target Company, business leaders should understand the overall historical tax risk profile of the target Company and how to obtain contractual protection for historical tax risks. It’s also important to consider how the acquisition could impact future tax planning and whether any potential tax attributes or step-up in tax basis are available that may impact the deal.
