OWR (Opgaaf Werkelijk Rendement) is the actual return declaration for Box 3 assets. Since 2023, taxpayers can opt to pay tax based on their actual investment returns rather than the fictitious return (forfaitair rendement).
This declaration is relevant for anyone with Box 3 assets: savings, investments, foreign property. It is especially beneficial when your actual return on capital was lower than the calculated forfaitair rendement — for example, if your money sat in a bank account earning minimal interest.
Filing an OWR can significantly reduce your Box 3 tax liability. If the Belastingdienst's calculated return exceeds your actual return, you're entitled to a refund. For clients with substantial savings, the savings can amount to hundreds or thousands of euros.
Calculation of actual returns across all asset categories, comparison with forfaitair rendement, preparation and filing of the OWR, and follow-up until the outcome is received.
