There's a lot of confusion surrounding crypto taxation: does it qualify as an exemption, speculative income, movable income, or professional income? And what about the rules regarding normal, responsible management? We provide clear advice on the tax treatment of your crypto portfolio and guide you through filing a correct tax return.
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
We are regularly contacted for a full review of crypto portfolios to verify whether everything has been correctly declared in the past. This is often done with a view to bank records or the upcoming transparency regulations under DAC8, which will give the government access to crypto transactions.
Tax review of your crypto portfolio
The crypto sector in Belgium encompasses more than just investments. We also support companies, freelancers, and professionals active in the sector, such as blockchain startups, investment funds, and hardware wallet developers, with targeted tax and legal support.

Assistance with tax audits and disputes with the tax authorities
We have extensive experience with the tax treatment of various crypto income, including staking, (liquid) mining, liquidity pools, launch pools, airdrops, token rewards, yield farming, liquidity mining, token vesting, referral bonuses, ICOs/IDOs, and bridge rewards. We help you qualify and structure these correctly within the Belgian tax framework.
Tax guidance for complex crypto income such as staking, lending and airdrops
Wondering how your crypto portfolio is treated tax-wise? We offer specialized tax advice on cryptocurrency and guide you through declaring income from staking, liquidity pools, launch pools, or RCUs. We analyze your transactions and help you optimize your tax position. If any tax errors come to light, we'll assist you with regularization.
Bank compliance
Do you want to transfer crypto profits to a Belgian bank account? We'll guide you through the tax requirements, ensure correct documentation, and have extensive experience with questions about the origin of assets. Banks often have additional questions in this regard based on anti-money laundering legislation, and we offer targeted support with expert advice.
