A business merger is the umbrella term for combining two or more enterprises. This can be done via three legal routes: a legal merger (one legal entity is absorbed into another), a share merger (shareholders exchange shares), or an asset and liability merger (separate assets and liabilities are transferred). The choice depends on tax, legal, and practical considerations. Duration: one to six months, depending on complexity. Costs: several thousand to tens of thousands of euros.

Tom — an entrepreneur with two limited companies after five years of growth — is considering a merger between his operating company and that of a former business partner. Which route is the right one? Below are the options, with the pros and cons listed.

The short answer

  • Legal merger: one private limited company (BV) is absorbed into another; assets under universal title. Notarial deed, Chamber of Commerce pre-registration, processing time 2–4 months.
  • Share merger: shareholders exchange shares for shares in another private limited company. Often tax-favorable via the merger exemption (Art. 3.55 Income Tax Act).
  • Asset-liability merger: only selected assets and liabilities are transferred. No automatic continuation of contracts.

When do you choose which route?

Boards of directors consult on the merger of two companies

Legal merger suits:

  • Complete merger of two BVs into one.
  • Simplifying a group structure (e.g. merging an operating company into a holding company).
  • Wish to automatically transfer all contracts, permits, and personnel.
  • Tax planning: often tax-advantageous via specific routes.

Share merger suits:

  • Shareholders want to merge without changing the underlying private limited companies.
  • Tax optimization via the merger exemption.
  • Bringing in investors who receive shares in a new top-tier private limited company.

See share merger.

Asset-liability merger is suitable for:

  • Selective acquisition — not wanting everything from the other BV.
  • Desire to merge only valuable parts.
  • Tax strategy where asset and liability transfer is more advantageous.

See asset and liability agreement.

The general step-by-step plan

Regardless of the route, you go through:

  1. Strategic exploration: does the merger suit both companies? Who will be responsible for what?
  2. Letter of intent / termsheet: non-binding document containing main conditions.
  3. Due diligence: financial, legal, tax, and commercial investigation of both BVs. See due diligence.
  4. Negotiating valuation, structure, and terms.
  5. Legal execution: notarial deed (in the case of a legal merger or share transfer), Chamber of Commerce procedure, possibly tax rulings.
  6. Integration: personnel, systems, contracts, customers.

How much does a merger cost?

  • Legal assistance (legal expert/lawyer): €5,000 – €25,000 for SME mergers.
  • Accountant + tax specialist: € 3.000 – € 15.000.
  • Notary: €1,000 – €3,000 for the merger deed.
  • Due diligence (external): € 2.000 – € 10.000.
  • Any Chamber of Commerce fees and publications: a few hundred euros.

Total for an SME merger: €10,000 – €50,000. Significantly higher for larger transactions.

Personnel during a merger

Consult with a lawyer regarding the merger process

Staff generally transfer automatically — in the case of a legal merger and business transfer pursuant to Art. 7:662 et seq. of the Dutch Civil Code. What that means:

  • Employees retain their rights and terms of employment.
  • The new employer takes over the employment contracts.
  • Non-negotiable — the employer cannot shorten this.
  • For the Works Council: prior advice required (Art. 25 WOR).

In the case of an asset-liability merger, a transfer of undertaking applies if the merger qualifies as a transfer of an “economic unit” — almost always in the case of complete business transfers.

Tax aspects

  • Legal merger: often tax-neutral via the facility of Art. 14b of the Corporate Income Tax Act (silent merger).
  • Share merger: exempt under Art. 3.55 Income Tax Act (merger exemption) — exchanging shareholders without immediate settlement.
  • Asset-liability merger: generally more tax-complex; settlement of hidden reserves possible.

Discuss with an accountant or tax specialist which route is most tax-efficient — the difference can save tens of thousands of euros in taxes.

Honest recommendation

A business merger is not a ready-made product. The right route depends on tax, legal, and practical factors. Invest in advance in a joint exploration with a lawyer, accountant, and tax specialist — a merger without thorough preparation leads to costly corrections later on.

For the specific routes: legal merger and share merger.

Frequently Asked Questions

What is a business merger?

The umbrella term for the merging of two or more companies. This can be done via three routes: legal merger (one legal entity is absorbed into the other), share merger (exchanging shares), or asset and liability merger (selective transfer of assets and liabilities).

Which form of merger should I choose?

Legal merger for full consolidation into a single entity. Share merger for consolidation at the share level without modifying the underlying BVs. Asset and liability merger for selective acquisition. The choice depends on tax, legal, and practical considerations.

How long does a merger take?

Typically 2–6 months, depending on complexity, due diligence, and the negotiation phase. A legal merger via notarial deed requires a statutory one-month pre-registration period with the Chamber of Commerce; the entire cycle often takes 3–4 months.

What happens to the staff?

In the case of a legal merger and transfer of business, employees automatically transfer under the same conditions (Art. 7:662 et seq. of the Dutch Civil Code). Non-negotiable. In the case of a Works Council: prior advice is mandatory. In the case of an asset-liability merger, there is also an automatic transfer if there is a “transfer of undertaking”.

How much does an SME merger cost?

€10,000 – €50,000 total for legal advice, accountant, tax advisor, notary, and due diligence. Significantly higher for larger or international transactions. Estimate in advance with all advisors.

Is a merger tax neutral?

Often this is possible via facilities such as Article 14b of the Corporate Income Tax Act (silent merger) or Article 3.55 of the Income Tax Act (merger exemption). The conditions are strict. A tax specialist can assess which route is most tax-advantageous.

Do I need a lawyer, or is a legal expert sufficient?

For most SME mergers, a specialized SME lawyer is sufficient. For large or international transactions, complex due diligence, or anticipated disputes, an M&A lawyer is advisable. Discuss your situation in advance — specialized guidance prevents costly mistakes.

Please note: an article provides general information, but your legal situation may turn out differently.
