What value does tax advisory for M&A transactions bring to businesses?

Tax advisory for M&A transactions has long been one of the indispensable services for businesses in identifying potential tax risks and ways to save on taxes. It is forecasted that M&A activities in Vietnam will regain momentum and may achieve a growth rate of 100% starting from early 2022, after the COVID-19 pandemic is brought under control. This is considered an opportune time for businesses to seize the opportunity for significant growth. Post-pandemic is the right time for companies to "restructure" after the "storm" has passed. To achieve a successful M&A deal, businesses need tax advisory from top experts.

Tax advisory for M&A transactions has long been one of the indispensable services for businesses in identifying potential tax risks and ways to save on taxes.

1. What is M&A?

M&A is an acronym for the combination of the words "Mergers" and "Acquisitions." It is a broad term that describes the process of integrating companies or assets through various financial transactions, including mergers, acquisitions, consolidations, takeovers, asset purchases, and management buyouts.

Mergers involve the consolidation of businesses of similar size, resulting in the creation of a new legal entity. All the assets, common interests, rights, or obligations of the merged or acquired business become the property of the merged entity.

Acquisitions, on the other hand, involve a larger company purchasing smaller and weaker businesses, and the acquired businesses retain their legal status as separate entities. The acquiring company gains legal ownership and control over the acquired business.

2. Forms of M&A


Horizontal mergers occur between two companies operating in similar industries, and they may be direct competitors or not.

One of the most prominent examples of horizontal M&A is the merger of Facebook, WhatsApp, Instagram, and Messenger. These were all independent social networking platforms developed by different companies at different times. These platforms merged into a larger social media company, Facebook Inc., owned by Mark Zuckerberg. One of the reasons for the merger with WhatsApp was to develop and implement end-to-end encryption technology to protect user privacy. While the websites and apps remain separate, users can freely interact across these applications on a single network. Additionally, when Facebook reached a certain maturity, mergers were a strategic move to drive further growth.


Vertical integration occurs between a company and its suppliers or customers within the company's supply chain. The company aims to expand either upstream or downstream along its supply chain, thereby strengthening its position in the industry.

The merger and acquisition deal between Walt Disney and Pixar is a famous example of vertical M&A. Walt Disney acquired Pixar Animation Studios for $7.4 billion in 2006. Pixar was a creatively driven animation studio with a talented workforce, while Walt Disney was a mass media and entertainment company. This merger brought significant success and was a strategic move for Walt Disney.

Conglomerate Merger

This is a form of acquisition and merger that creates conglomerates. Conglomerate mergers occur between companies serving the same customer base in a specific industry, but they do not offer the same products and services.

A well-known example of a combined merger is the deal between Berkshire Hathaway and Heinz in 2013. This acquisition paved the way for Heinz to merge with Kraft, forming Kraft Heinz, a giant in the global food industry.

M&A is an abbreviation for the term "Mergers and Acquisitions." It is a general term describing the consolidation of companies or assets through various financial transactions, including mergers, acquisitions, consolidations, takeovers, asset purchases, and management buyouts.

3. The role of a tax advisor in M&A transactions

A skilled tax consultant with ample experience can make a significant contribution to helping businesses save on taxes. In practice, there have been tax consultants for M&A deals who have helped businesses save up to 20% on taxes – a substantial amount for any business.

Tax consultants analyze tax-related issues concerning your business, the acquiring company, and other parties involved in the M&A transaction to assess overall feasibility and post-restructuring cash flows. Additionally, the tax structuring goals of both the seller and the buyer in the deal are crucial factors. These objectives can change significantly depending on the restructuring and post-merger integration.

Tax due diligence also plays a critical role in identifying potential tax risks in the target company. Tax consultants for M&A deals aim to address and mitigate potential tax risks with the primary goal of putting the business's interests first. When developing a tax due diligence process, the analysis goes beyond simply reviewing tax returns. Businesses need to comprehensively analyze the tax attributes of the company, as well as determine the tax status, business flows, organizational ownership, location, and industry.

Tax consultants for M&A deals evaluate the tax components of the acquisition, structure the acquisition to optimize cash flows, prepare for business integration, conduct pre or post-sale due diligence, and ensure compliance with tax requirements.
