Tax Adviser or M&A Adviser: Who Really Gets Your Business Sale Across the Finish Line?

Tax Adviser or M&A Adviser: Who Really Gets Your Business Sale Across the Finish Line?

"My accountant takes care of everything" — this is one of the most common answers M&A advisers hear when asking business owners about their sale strategy. The statement is understandable: the accountant has accompanied the business for years, knows the figures, and enjoys deep trust. But when it comes to selling a business, this trust alone is not sufficient. Tax advisers and M&A advisers are not competitors — they cover fundamentally different areas of expertise, and both are needed.

What Tax Advisers Contribute to a Business Sale

An experienced tax adviser is indispensable in a business sale — in the area of tax structuring. The fundamental question of Asset Deal versus Share Deal has enormous implications for the tax burden on both sides: in an Asset Deal, the buyer acquires individual assets and can claim depreciation, while the seller is often taxed at a higher rate. In a Share Deal, GmbH shares are transferred, which can be more tax-efficient for the seller — provided the ownership structure is set up correctly.

A competent tax adviser examines whether a preliminary restructuring via a holding company makes sense in order to optimise the taxation of the disposal gain. They also accompany the tax Due Diligence on the seller's side and identify potential tax risks that must be secured in the purchase agreement.

Where the Tax Adviser Reaches Their Limits

What tax advisers generally do not provide — and cannot provide — is the operational side of the transaction process. The decisive difference lies in core competence: tax advisers are specialists in law and taxation, not in M&A markets and negotiation processes.

• Asset Deal vs. Share Deal analysis
• Holding optimisation before sale
• Tax Due Diligence
• Minimising profit taxation
• Annual financial statements and figures

• Active buyer identification
• Organising a competitive bidding process
• Valuation report with market comparison
• Negotiation management & tactics
• NDA and data room management

Particularly significant is the lack of capability for active buyer identification: a tax adviser has no structured access to strategic acquirers or private equity investors. They can respond to enquiries — but they do not initiate a competitive process. Yet precisely this process is the decisive lever for maximising the purchase price.

Equally absent is the expertise for a professional valuation report with market comparison: the company valuation by an M&A adviser is based on current transaction data, sector multiples, and a strategic analysis of buyer value — far beyond what a tax adviser can derive from annual financial statements.

The Statistic That Gives Pause for Thought

The reason does not lie in a lack of commitment on the part of the tax adviser. It lies in the fact that transaction processes are a discipline entirely of their own — with specific market knowledge, networks, negotiation tactics, and process architectures that are built up over decades of transaction experience.

What an M&A Adviser Provides That the Tax Adviser Cannot Replace

The M&A adviser brings three core services to the process that no other professional group can substitute. First: buyer access and market knowledge — an experienced adviser knows which strategic buyers are active in the relevant segment, which private equity funds invest at this scale, and how to approach these prospects discreetly and purposefully. Second: process architecture — the entire sequence from teaser to signing is systematically planned and managed, with clear deadlines, information hierarchies, and escalation levels. Third: negotiation management — an M&A adviser negotiates transactions on a daily basis and knows the psychology, tactics, and pitfalls of complex purchase price negotiations from practical experience.

The Optimal Solution: Three Experts, One Goal

The model that delivers the best results in practice is the three-person team: M&A adviser, tax adviser, and a lawyer specialising in M&A. Each expert handles their core area — and all three work in a coordinated manner towards the same goal: the best possible outcome for the seller.

The M&A adviser leads the overall process, identifies buyers, maximises the price, and steers the negotiations. The tax adviser optimises the structure before and after the sale. The M&A lawyer protects the seller in the purchase agreement, negotiates warranties and liability clauses, and ensures legal clarity. Anyone who engages only one of these three experts risks blind spots — with potentially significant financial consequences.

The good news: in practice, good M&A advisers know experienced tax advisers and lawyers from joint transactions and can make recommendations. This saves the time-consuming search for a well-coordinated team.
