Box 3 filing
Start with the Aangifte Copilot to surface Box 3 exposure first, then continue with the exact follow-up steps and calculators that matter for your filing.
The copilot lets you declare Box 3 exposure up front so the filing review is not starting from a blank state.
Belastbaar can then recommend the Box 3 calculator and related follow-up only when it is relevant to your case.
You keep a side-by-side overview of what is estimated, what is confirmed, and what must still be entered manually.
Year-end bank statements, broker statements, debt overviews, and supporting documents for crypto or foreign accounts are usually the most important.
Because the filing copilot first determines whether Box 3 is actually relevant and then puts the Box 3 follow-up in the wider filing context.
