Why we exist

Taxes shouldn't be the investor's punishment.

Modern investment apps have made the stock market accessible to everyone. But they left Belgian investors alone facing a complex tax system — an unwithheld stock-exchange tax, a new tax on capital gains, accounts to declare. Benchmarkr was born to fill that gap.

The problem we solve

By leaving Belgian banks for cheaper foreign platforms, thousands of investors unknowingly inherited obligations their bank used to handle for them: declaring and paying the stock-exchange tax, computing their capital gains, reporting their foreign accounts — under penalty of fines.

Benchmarkr brings all your accounts together, computes what you actually owe and helps you file — to stay compliant without paying more than necessary.

What sets us apart

Built for Belgium

Stock-exchange tax, 2026 capital gains, opt-in/opt-out, Central Point of Contact: we handle the specific Belgian tax rules, not a generic calculation.

An overview, at last
