Netherlands updates taxable incorporation backdating procedure

The policy concerns a taxable contribution—ruisende inbreng—rather than a tax-neutral incorporation. Ordinarily, the transition from income-tax treatment to corporation-tax treatment cannot precede the preliminary agreement. The decision nevertheless permits an inspector, on written request, to recognise a preliminary period of up to three months before that agreement when an enterprise or qualifying activity is contributed to a Dutch private or public limited company.^[1]

Core conditions remain

The preliminary agreement must be concluded within three months after the requested transition date. Retroactivity must not produce an incidental tax advantage; the new wording expressly treats a one-off receipt of €100,000 or more during the retroactive period as such an advantage. The taxpayer may not claim income-tax entrepreneur facilities for that period, the company and contribution must be completed within nine months, the facts must be complete, and both taxpayer and company must accept the conditions in writing.^[1]

Registration is removed, but filing becomes more prescribed

The 2026 decision removes the former requirement to register the preliminary agreement or unilateral declaration of intent with the tax administration. It also removes the earlier six-week deadline for the administration to receive the parties’ acceptance statements. In place of the old registration process, the request and agreement must be sent by registered post using the prescribed covering form as soon as possible and no later than the income-tax return for the year in which the preliminary period begins. The inspector still decides whether to grant the requested retroactivity.^[1][2]

Implications for business restructurings

The change simplifies evidence of the incorporation intention but does not create automatic backdating or change the three- and nine-month limits. Entrepreneurs and groups reorganising Dutch activities into a BV or NV should document the intended transition date, screen unusual receipts during the preliminary period and retain proof of registered dispatch. The €100,000 example is a specified minimum case of incidental advantage, not a general safe harbour below that amount. Decision CPP2008/1626M is withdrawn, and the new policy applies from 23 October 2026.^[1][2]
