Since the introduction of Belgium's new capital gains tax in 2026, uncertainty surrounding the tax treatment of cryptoassets has increased further. Do crypto gains fall within the normal management of private assets, or do they constitute speculative, professional, or movable income? The criteria concerning prudent private management, speculation, and abnormal management also remain the subject of considerable debate in practice.
Crypto and tax returns
When crypto profits are deposited into a Belgian bank account, banks often ask questions about the origin. We provide fast and accurate support for KYC requirements. In many cases, it's advisable to create a file beforehand to avoid problems with the transfer.
Compliance and banking questions about crypto
Tax authorities and police are increasingly asking questions about cryptocurrencies in the context of tax fraud and money laundering investigations. We help you put your case into context, refute accusations, and provide support during interrogations, inspections, and criminal proceedings.
Assistance with suspected tax fraud and money laundering
