Become a beta tester for our accountant access to BelgianTaxCalculator - join the waitlist!

Managing investment taxes for clients who use foreign brokers is time-consuming, error-prone and there is no single tool in Belgium that handles it properly.

Belgian Tax Calculator is changing that! We are building a dedicated accountant portal that brings TOB, dividend tax and the new 2026 capital gains tax (meerwaardebelasting) together in one place, with full support for CSV imports foreign brokers like IBKR, DEGIRO, Trade Republic, Bolero, Kraken, Binance and other foreign brokers and crypto exchanges.

We are currently looking for a small group of accountants to join our private beta, test the platform with real client data, and help us shape the final product before public launch.

After launch, the portal moves to a paid annual plan. Beta testers will receive early access pricing.
