Transaction Advisory

A transaction is one of the most significant events in the life of a business – and tax sits at the heart of whether it delivers its intended value. From the earliest stages of deal structuring through to post-completion integration, the tax decisions made during a transaction have a lasting impact on returns, risk, and commercial outcomes.

Our advisers work with business owners, corporates, and investors across the full transaction lifecycle, providing tax counsel that is commercially grounded and timed to the pace of deals. We work closely with our corporate finance colleagues, ensuring that tax and financial due diligence are joined up from day one.

Tax Due Diligence

Understanding the tax profile of a target business is fundamental to assessing deal risk. Our tax due diligence work gives buyers a clear picture of historic exposures, ongoing compliance quality, and issues that may affect price or structure.

  • Buyer-side tax due diligence on Irish and international targets
  • Identification and quantification of tax exposures
  • Vendor tax due diligence and preparation for sale
  • Red flag and long-form reporting to suit deal timelines

Transaction Structuring

How a deal is structured determines how the proceeds are taxed — for sellers, and how efficiently the acquisition can be financed and held — for buyers. Getting this right at the outset avoids costly restructuring later.

  • Acquisition and disposal structure advice
  • Holding company and group structure design
  • Debt and equity structuring for acquisitions

Post-Acquisition Restructuring

The period following a transaction often requires significant reorganisation — of legal entities, financing structures, and operating models. We advise on the tax-efficient implementation of post-deal integration and restructuring plans.

  • Group reorganisation and simplification
  • Intragroup transfer and hive-out structuring
  • Debt restructuring and refinancing advice post-acquisition
  • Integration of acquired businesses into existing group structures

Cross-Border & International Tax

Transactions involving Irish businesses with international operations, or overseas acquirers investing into Ireland, require careful navigation of multiple tax regimes, treaty networks, and transfer pricing rules.

  • Inbound investment structuring into Ireland
  • Irish outbound acquisition and holding structure advice
  • Transfer pricing considerations on cross-border transactions
  • Permanent establishment and withholding tax analysis

Working Alongside Corporate Finance

Tax and financial due diligence are most effective when they run in parallel, share information, and speak with a single voice to clients and counterparties. Our corporate finance team advises on financial due diligence, deal origination, valuations, and the broader M&A process – giving clients access to fully integrated transaction support under one roof.
