You chose the freedom to invest. Stay in control of your taxes.
Modern investment apps and platforms set you free. But when it comes to the Belgian tax authorities, they leave you on your own. Benchmarkr helps you see clearly: your taxes and capital gains computed, and the right approach so you don't pay more than necessary.
What your investment platform doesn't tell you
With an online bank or a trading app, the Belgian tax office doesn't forget you — it's waiting for you.
A stock-exchange tax no one withholds for you. Every trade generates one, and it's up to you to declare it.
A new tax on capital gains: 10%, from 2026. Poorly anticipated, it can cost you.
The risk of overpaying, without knowing it: automatic withholding ignores your exemption and your losses.
A foreign account to declare every year, under penalty of sanctions.
