Two founders agree that their companies belong together. One has the stronger balance sheet. The other has valuable customers, skilled staff and a product that would take years to build. Cash is scarce, so they settle on shares. The transaction appears elegant: combine the businesses without emptying either bank account.
Dutch tax law allows that outcome through several routes, each with its own conditions. Article 3.55 of the Income Tax Act addresses qualifying share mergers. Article 14 of the Corporate Income Tax Act covers business mergers, supported by the Bedrijfsfusiebesluit 2025. A legal merger follows separate company-law rules and transfers an entire estate by universal succession.
Those distinctions matter because the object being transferred changes. It may be the founder’s shares, the operating business and its assets, or the complete legal entity. Each route moves value differently. It also changes who carries the tax claim, which voting rights count and which liabilities arrive with the deal.
Tax deferred is tax carried forward
For a qualifying Dutch share merger, the acquiring company generally issues its own shares or profit-sharing certificates and obtains more than half of the voting rights in the acquired company. If the rollover applies, the gain can be left out of account. The historic acquisition price moves into the replacement shares.
That is deferral, not forgiveness. The tax claim remains attached to the founder’s new position. If the arrangement does not qualify, a shareholder with a substantial interest may face Box 2 tax on a disposal gain. In 2026, Box 2 income is taxed at 24.5 per cent up to €68,843 and 31 per cent above that amount.
The cash tension is immediate. A founder may receive mainly illiquid shares while the tax calculation follows the value of the disposal. The transaction can look cash-free at the notary’s table and still create a personal liquidity problem. Dutch law also allows a taxpayer to request an advance, appealable decision on whether a proposed transaction qualifies, provided the request comes before the disposal.
Voting power is more than a percentage
The voting-rights test deserves more attention than it usually receives in an early deal conversation. A 2026 Belastingdienst position confirms that the surrounding arrangements can matter when a share merger is followed by another restructuring step. The sequence is read as a whole, not merely as a collection of separate notarial acts.
The point becomes sharper where a STAK is involved. A STAK separates economic rights from voting rights. In July 2026, the Belastingdienst stated that certified shares can enter a qualifying share merger only where the voting-rights condition is actually met. An economically balanced exchange does not automatically produce the legal control required by the facility.
I read this as a governance question before it is a tax question. Who can vote after completion? What do the shareholder agreement and certification terms permit? Are later steps already agreed? If the commercial presentation says one thing while the legal rights say another, the transaction carries friction from its first day.
The exchange ratio carries the real bargain
Return to our two founders. Suppose one company is valued at €500,000 and the other at €250,000. Those headline values suggest a two-thirds and one-third economic division after the combination. They do not, by themselves, determine how many shares should change hands. Share classes, voting rights, dividend preferences, debt and restrictions can alter the real outcome.
The seller is also exchanging certainty for exposure. Cash has a fixed nominal amount. Buyer shares depend on the future performance, financing and governance of the combined company. If the larger business later loses a major customer, the consideration falls with it. The seller has not merely transferred a company. The seller has reinvested the sale proceeds into the buyer.
That is why I would expect the exchange ratio to connect directly with the accounts and assumptions used in negotiations. Revenue quality, overdue debtors, tax positions, director loans and hidden investment needs can all change the value behind a polished number. The ledger should tell the same story as the term sheet.
Different routes carry different history
A business merger moves an enterprise, or a qualifying independent part of one, in exchange for shares. The current policy framework is the Bedrijfsfusiebesluit 2025. Article 14 contains conditions concerning tax continuity, losses and other tax attributes. It also restricts transactions predominantly aimed at avoiding or deferring tax.
Business reasons therefore need substance. Restructuring active operations or combining them more rationally can support the route. A disposal within three years to an unconnected body creates a rebuttable presumption that business reasons were absent. A later sale is not automatically fatal, but it can change how the original transaction is read.
A legal merger goes further. Under Article 2:309 of the Civil Code, the assets of a disappearing legal person pass by universal succession. Contracts, debts, records and liabilities travel with that estate. Creditors gain visibility through the filed merger proposal and may seek security or consider opposition. This is not simply an asset deal with fewer signatures.
The morning after completion
For a small company, the useful discipline is to connect tax, control and business reality before the structure hardens. The valuation should explain the exchange ratio. The legal documents should show the actual voting position. The accounts should identify tax attributes, debts and obligations that continue. The business rationale should still make sense without the tax deferral.
Our two founders will eventually return to ordinary work: customers, wages, supplier calls and monthly cash. Their relationship, however, will have changed permanently. One may hold less control than expected. The other may have accepted more historic risk than the valuation recognised. Both may carry a deferred tax position that becomes relevant years later.
Shares can preserve cash, and that can make a good combination possible. They do not remove the price. They move it into ownership, future performance and tax continuity. A sound merger begins when the founders understand that shift clearly, while there is still time to reconsider the bargain.
