    Request for reduction after recalculation of box 3 income

    You have received a letter about the recalculation of your box 3 income and you disagree with our decision. Does the letter say that you can file a request for a reduction (verzoek tot vermindering) in that case? If so, you can read what to do here.

    In your request, please specify what you disagree with

    In your request, you must indicate what it is you disagree with. Understanding how the new calculation of the income in box 3 works, will help you write a better motivation for your request. See how we calculate your new box 3 income with the Hulpmiddel Box 3-inkomen (Box 3 Income Tool, only available in Dutch).

    Have your assessment number ready

    You can find this number on the decision you received about your new income in box 3. If your old income in box 3 is more advantageous to you, please use the number of your old final assessment. You can also find this assessment online in Mijn Belastingdienst (only available in Dutch).
