Dutch taxpayers are required to declare cryptocurrency holdings as “other assets” (overige bezittingen) in their annual tax returns. These holdings are to be reported at their market value as of January 1 of the tax year.
Consequences of Non-Compliance
In practice, it is observed that crypto holdings are sometimes omitted from tax declarations, either intentionally or unintentionally. If the Dutch Tax Authority (*Belastingdienst*) discovers such discrepancies, this could result in reassessments, with penalties reaching up to 300% of the unpaid taxes.
DAC 8 Directive Coming in 2026
From 2026, the DAC 8 directive will take effect. Under this directive, cryptocurrency service providers will be required to share user data with tax authorities. The first exchange of such data is scheduled for January 31, 2027. If it emerges from these data exchanges that taxpayers have failed to report their cryptocurrency holdings, the tax authority may impose penalties and initiate retroactive reassessments.
Look-Back Periods and Penalties
Depending on the case, the reassessment process can examine tax returns for the past five or even twelve years. When penalties are included, this could lead to significant financial consequences for taxpayers.
Our recommendations
To avoid such complications, it is strongly advised to voluntarily correct past tax returns (a process known as *inkeren* in Dutch). This can often significantly reduce potential penalties while allowing you to retain some control over the process.
Cryptocurrency taxation is particularly complex, given ongoing developments in Dutch case law (*Rechtspraak* or *Jurisprudentie*) and recent rulings by the Dutch Supreme Court (*Hoge Raad der Nederlanden*) concerning Box 3 (as mentioned in this newsletter) taxation and the consideration of actual returns on assets.
