The Dutch box 3 overhaul is not law yet. The draft is.
From 2028: 36 percent tax on your actual yearly result.
Stocks: taxed when you sell.
Bitcoin in your own wallet: taxed on paper gains every year, expected until 2030.
We ran an example for a parent.
50k euro in savings, 50k euro in bitcoin. Bitcoin goes up 50 percent.
Current 2026 rules: 880.54 euro tax.
2028 proposal: 10,872 euro.
Without selling a single sat.
The bitcoin you stack for your kid? It counts with you. The child gets no exemption of its own.
Inflation is ignored too.
We put the rules, the open questions and a tool to run your own numbers in one place. Not advice, just math.
