Cryptocurrencies continue to grow in popularity, but they also bring important tax obligations. In the Netherlands, crypto assets must be reported as “other assets” (overige bezittingen) in your annual income tax return—valued at their market price on 1 January of each tax year.
The risks of not reporting your crypto
Omitting crypto from your income tax return—whether by mistake or intentionally—can have serious consequences. If the Belastingdienst uncovers discrepancies, it can issue additional assessments and impose penalties of up to 300%. These surprises are best avoided.
From 2026, the new DAC8 directive will significantly increase transparency. Crypto service providers will be required to share user information with tax authorities across the EU, with the first data exchange planned for 31 January 2027. If undeclared crypto comes to light during these exchanges, the Belastingdienst can still impose penalties and open retroactive investigations.
Depending on the situation, the tax office can review your income tax returns for up to five years, and in some cases twelve years. When penalties are added, this can quickly lead to substantial financial exposure.
Our recommendation: stay ahead
To protect yourself, we advise proactively correcting past income tax returns (inkeren). Voluntary disclosure often reduces penalties and keeps you in control.
Crypto taxation is a fast-moving field. Ongoing case law and recent Supreme Court rulings around Box 3 taxation and actual returns make it more important than ever to ensure your reporting is accurate and up to date.
