A merger generally triggers taxation as if it were an ordinary sale. But if the merger meets the conditions under Danish merger tax law, it can be carried out tax-free — which can make a significant difference to the owners of the companies involved.

What's the main rule?

The basic condition for tax exemption is that the owners of the transferring company (the company that ceases to exist) are compensated exclusively with shares in the receiving company — possibly supplemented by a small cash balancing amount. If too much cash is paid, the merger loses its tax exemption.

Why is this required?

The idea behind the rules is that a tax-exempt merger shouldn't trigger taxation because the owners haven't actually "sold" anything — they've merely converted their ownership stake into a new form. If they instead receive cash, it looks more like a sale, and is taxed as one.

Other key conditions

  • The merger must be carried out correctly under Danish company law
  • As a general rule, the companies must be tax resident in Denmark or a country Denmark has a double taxation treaty with
  • Cross-border mergers are subject to special, more complex rules

What happens if the conditions aren't met?

Then the merger becomes taxable, as if it were an ordinary sale of assets or shares — with the taxation that entails for the companies and owners involved. There's a genuine legal right to tax exemption if the objective conditions are met, but if you fail one of them, there's no discretion to fall back on.

Merger as an alternative to a sale

A tax-exempt merger can in certain situations be an alternative to an ordinary sale — e.g. for a generational transfer or a merger with a business partner. See when it makes sense in Merger of Companies: When Is It an Alternative to a Sale?

Frequently asked questions

Can a merger always be carried out tax-free if both parties want it?

No, it requires the objective conditions under Danish merger tax law to be met — it's not something the parties can simply agree to independently of the rules.

What does it mean that there's a "legal right" to tax exemption?

It means the tax authorities can't discretionarily deny the exemption if the conditions are objectively met — but conversely, they also can't grant an exception if they aren't.

Should I always involve an advisor for a merger?

Yes. The rules are complex, and the consequence of a mistake is real taxation — this isn't an area where it pays to skimp on advice.
