How do I declare my account to the Belgian tax authorities?

Your investment account is with NNEK in the Netherlands. This means you have to tell the Belgian tax authorities about your Dutch investment account. For that, you need to do two things.

1. Declare your account to the Belgian National Bank (once)

The instructions are in the Curvo app in your "Account" section, and are also available here. You need to do this once upon opening your account.

2. Mention the account on your tax form (every year)

We will give you detailed instructions every year. Use them when you complete your tax form. View the instructions for the tax year 2024
