Crypto Overview in Belgium

Regulatory data is for informational purposes only and may not reflect the most current legal developments. Always consult qualified professionals before making decisions.

Legal Classification and Regulatory Framework

Cryptocurrency Status

Cryptocurrencies are not legal tender in Belgium. The National Bank of Belgium (NBB / Nationale Bank van België / Banque nationale de Belgique) has stated that crypto-assets are not comparable to central bank money and carry no government guarantee. Despite this, buying, selling, holding, and trading crypto-assets is entirely legal. Depending on their characteristics, crypto-assets may be treated as movable property or as financial instruments under Belgian law. Tokens with profit-sharing features or underlying asset claims often qualify as regulated financial instruments, triggering prospectus and conduct-of-business obligations.

Tax Treatment

Belgium applies its existing income tax framework to crypto-assets, with the outcome determined by the investor’s profile and behavior. Three categories apply. First, investors practicing normal management of private assets (the “bon pere de famille” principle) historically paid no tax on capital gains. From 1 January 2026, those gains are subject to a flat 10% tax, with an annual exemption of 10,000 euros. Unused exemptions may be carried forward up to 5,000 euros per year for a maximum of five years. The historical portfolio balance as of 31 December 2025 is exempt from this new tax.

Second, investors whose activity is deemed speculative under Article 90 of the Income Tax Code (Wetboek van de Inkomstenbelastingen 1992 / Code des impots sur les revenus 1992) remain taxed at a flat 33% plus municipal surcharges. Indicators of speculation include high transaction frequency, holding more than 20 to 25 percent of total movable assets in crypto, and use of borrowed funds. Third, professional traders pay progressive rates up to 50% plus social contributions. Corporate entities pay the standard corporate income tax rate of 25%.

Passive crypto income such as staking rewards and lending interest is taxed at 30% as capital income or as miscellaneous income depending on circumstances. From 1 January 2026, the DAC8 directive requires EU crypto-asset service providers to automatically report customer transaction data to national tax authorities, sharply reducing anonymity for Belgian crypto holders. Advance tax rulings can be sought from the Service des Decisions Anticipees (SDA / Dienst Voorafgaande Beslissingen, DVB).

Regulatory Oversight

Belgium operates a Twin Peaks supervisory model. The Financial Services and Markets Authority (FSMA / Autoriteit voor Financiele Diensten en Markten / Autorite des services et marches financiers) oversees market conduct, consumer protection, and the authorization of most crypto-asset service providers. The NBB handles prudential supervision of financial institutions, including those issuing asset-referenced tokens (ARTs) and e-money tokens (EMTs).

MiCA (Regulation EU 2023/1114) has been directly applicable across the EU since 30 December 2024. Belgium formalized the domestic supervisory split through the Law of 11 December 2025, published in the Belgian Official Gazette on 24 December 2025 and in force from 3 January 2026. The FSMA is exclusively competent for authorizing Article 63 CASPs (pure-play crypto service providers), reviewing crypto-asset whitepapers, and enforcing market abuse rules. The NBB is competent for prudential supervision of ARTs, EMTs, and CASPs that are already supervised credit institutions or payment institutions.

AML compliance is mandatory for all registered service providers under the Law of 18 September 2017 on the prevention of money laundering and terrorist financing. The Financial Intelligence Unit is the CTIF/CFI (Cellule de Traitement des Informations Financieres / Cel voor Financiele Informatieverwerking). Obligations include customer due diligence, transaction monitoring, and risk-based controls.

Business Environment

Banking Relationships

Major Belgian banks generally permit SEPA transfers to EU-licensed crypto exchanges, subject to internal compliance checks. Banks may request documentation on the origin of funds for larger amounts or when customers repatriate crypto proceeds. Crypto businesses seeking banking services face ongoing challenges: many traditional banks remain reluctant to serve the sector, and companies may need to approach multiple institutions or fintech-oriented banks. The NBB has issued guidance to financial institutions on managing crypto-asset exposures, including expectations on risk management aligned with Basel Committee standards.

Innovation Support

The FSMA and NBB jointly operate a FinTech Contact Point, providing a single regulatory entry point for fintech and blockchain entrepreneurs to receive guidance on applicable law without needing to determine which authority is relevant to their business.

The Blockchain4Belgium initiative brings together industry, academics, civil society, and government bodies to present recommendations on strategic blockchain deployment to the federal government. Belgium also participates in EU-level infrastructure through the European Blockchain Services Infrastructure (EBSI). Belgian financial institutions have conducted pilot projects in tokenized bond settlement and trade finance using blockchain technology, drawing on expertise from local enterprise technology firms.

Crypto License in Belgium

Belgium’s CASP authorization framework is now fully operational under the Law of 11 December 2025, which formally designated the FSMA as the primary licensing authority for most crypto-asset service providers. Firms wishing to operate legally in Belgium and passport services across the EU must obtain authorization before the transitional period ends on 1 July 2026.

Licensing Requirements

Two authorization tracks exist under MiCA. Article 63 CASPs, covering most pure-play crypto exchanges, custodial wallet providers, and trading platforms, require full FSMA authorization. Article 60 CASPs, which are existing financial institutions providing crypto services equivalent to their current regulated activities, may notify compliance instead. Credit institutions and stockbrokers fall under this notification path; their prudential oversight remains with the NBB.

Minimum capital requirements range from 50,000 euros to 150,000 euros depending on the scope of services. Applicants must satisfy fit-and-proper requirements for management, demonstrate adequate governance structures, maintain documented conflict-of-interest policies, and implement ICT resilience measures. AML and KYC procedures must be designed to satisfy both MiCA requirements and the Belgian Law of 18 September 2017 within a single coherent compliance framework. MiCA sanctions reach up to 5% of total annual turnover or 5 million euros per breach.

Stablecoin issuers face specific obligations. ART and EMT issuers must meet reserve, transparency, and redemption requirements. The NBB handles authorization, capital requirements, and reserve arrangements for these token categories.

Authorized Activities

MiCA defines ten categories of crypto-asset services, including custody and administration, operating a trading platform, exchange services (crypto-to-fiat and crypto-to-crypto), execution of orders, portfolio management, reception and transmission of orders, placing of crypto-assets, and providing transfer services. A Belgian CASP authorization covers the specific services listed in the application. Once authorized, firms may passport services to other EU member states by notifying the FSMA, which then informs the host-state regulator.

The marketing of crypto-assets to Belgian consumers is regulated separately under the FSMA Regulation approved by Royal Decree of 5 January 2023 and in force from 17 May 2023. All advertisements must include the mandatory warning: “Virtual currency, real risks. The only guarantee in crypto is risk.” Mass campaigns reaching 25,000 or more Belgian consumers require prior notification to the FSMA at least 10 days before dissemination. The regulation extends to social media influencers paid to promote crypto-assets.

Application Process and Timeline

Applications for Article 63 CASP authorization are submitted by email to casp@fsma.be. The FSMA recommends scheduling a pre-application consultation before submitting a full dossier. This call clarifies expectations on dossier structure and required document formats, reducing back-and-forth with the regulator. Notification applications for Article 60 CASPs go to amc@fsma.be.

A complete application includes a program of activities, governance and ownership documentation, AML/KYC policy manuals, ICT and security blueprints, and evidence of financial resources in line with ESMA templates. The FSMA processes applications within the timeframes set by MiCA: 25 working days to assess completeness, then up to 40 additional working days to reach a decision. In practice, the full preparation-to-authorization timeline is estimated at 3 to 6 months depending on dossier quality.

Notably, no registrations were ever granted under the pre-MiCA Royal Decree of 8 February 2022; no applicant submitted a complete file before the rules expired. The first FSMA authorizations under MiCA will therefore be the first formal licenses ever issued to Belgian-based CASPs.

Market Characteristics

Adoption Patterns

Belgian consumers access crypto-assets primarily through EU-licensed platforms operating under MiCA or exercising EU passporting rights. Standard banking transfers fund most accounts. Exchange-traded products physically backed by Bitcoin and Ethereum are available through brokerage accounts, offering a traditional-securities entry point. Consumer protection has been strengthened through mandatory advertising risk warnings and enhanced MiCA disclosures. Belgian authorities have issued multiple warnings to retail investors covering total-loss risk, absence of deposit protection, and technology risks.

Industry Focus

Belgium has developed recognized strengths in enterprise blockchain and institutional crypto infrastructure. Keyrock (Brussels) provides algorithmic market-making and liquidity solutions across more than 85 trading venues globally. SettleMint (Leuven, founded 2016) operates an enterprise blockchain application platform active across Europe, the Middle East, and Asia, and received funding from the European Innovation Council. T-Mining (Antwerp, founded 2016) applies blockchain to port logistics, serving approximately 4,500 companies worldwide. Belgium’s position as host to major EU institutions gives local stakeholders direct access to EU regulatory policymaking.

Regulatory Trajectory

DAC8 automatic reporting, effective from 1 January 2026, means transaction data held by EU platforms on Belgian customers is automatically shared with Belgian tax authorities. The EU Anti-Money Laundering Authority (AMLA), headquartered in Frankfurt, will eventually take direct supervisory responsibility over high-risk CASPs, adding a third supervisory layer above FSMA and NBB for the largest operators.
