Quick answer — Belgium, 2026

• Legal: Legal to own and use, not legal tender; providers licensed under EU MiCA
• Tax: New 10 percent capital gains tax from 2026, with annual exemption
• Buying: Via MiCA-authorised exchanges, apps or banks after KYC

Bitcoin and other cryptocurrencies are legal to buy, hold, and sell in Belgium. They are not legal tender, only the euro is, and no one is obliged to accept crypto as payment, but owning and trading digital assets is permitted and the firms that provide crypto services are now formally licensed and supervised. Oversight follows Belgium's long-standing "twin peaks" model: the Financial Services and Markets Authority (FSMA) authorises crypto-asset service providers and handles conduct, consumer protection, and market integrity, while the National Bank of Belgium (NBB) handles prudential and systemic-stability matters, including issuers of certain stablecoins. Above both sits the EU's Markets in Crypto-Assets Regulation (MiCA), which provides a single rulebook across the bloc.

This guide explains how digital assets are treated in 2026, a year of significant change. A Belgian implementing law, the Law of 11 December 2025, was published in the Official Gazette on 24 December 2025 and entered into force on 3 January 2026, turning MiCA into an enforceable national regime. Separately, a new general capital-gains tax on financial assets, explicitly including crypto, applies to gains realised from 1 January 2026 at a 10 percent rate with an annual exemption. Below we cover legal status, the regulators, the key laws, licensing of exchanges, taxation, AML and KYC, buying and using crypto in practice, mining, recent developments, consumer risks, and how to verify everything with official sources. This is general information as of 2026 and is NOT legal, tax, or financial advice; rules and figures change and individual circumstances differ, so confirm specifics with the FSMA, the NBB, and the Federal Public Service (SPF/FOD) Finance, or a qualified Belgian adviser.

Yes. Buying, holding, selling, and using Bitcoin and other cryptocurrencies is legal in Belgium. What crypto is not is legal tender or an official means of payment: the euro is the only legal tender, and no one is required to accept crypto. Merchants may choose to accept it, and individuals can trade and hold it freely, including in self-custody.

The regulated part of the market is the infrastructure around crypto. Exchanges, brokers, custodians, and similar businesses, known under MiCA as crypto-asset service providers (CASPs), must be authorised and follow anti-money-laundering (AML) rules. For ordinary users the practical takeaway is simple: using a licensed, MiCA-compliant platform is both legal and the safest way to buy and store crypto. Advertising crypto to the Belgian public is also subject to FSMA rules, so promotional offers should come from authorised firms. For background, see our explainer on how crypto is regulated.

Belgium uses a "twin peaks" supervisory model, and the Law of 11 December 2025 divides crypto powers between two authorities.

• The FSMA (Financial Services and Markets Authority) authorises and supervises crypto-asset service providers and oversees conduct of business, consumer protection, advertising, and market integrity. Most CASPs are supervised by the FSMA. Its official site is the place to check licensing and warnings.
• The National Bank of Belgium (NBB) is the prudential and systemic-stability supervisor. It oversees issuers of certain stablecoins, namely asset-referenced tokens (ARTs) and e-money tokens (EMTs), and, by exception, supervises some CASPs that are already subject to its prudential oversight (for example credit institutions offering crypto services).

On tax matters, the relevant authority is the Federal Public Service Finance (SPF Finances / FOD Financien). A practical benefit of MiCA is "passporting": a CASP authorised in one EU member state can serve customers across the EU. Informational only, not legal advice; verify authorisations and the current rules with the FSMA and NBB.

Belgium's framework combines directly applicable EU law with national implementing legislation.

MiCA is the EU's harmonised regulation for crypto-asset markets, covering the public offering and admission to trading of tokens, the provision of crypto-asset services by CASPs, stablecoins, and market-abuse prevention. Its rules for CASPs became directly applicable across the EU at the end of 2024.

Belgium initially lacked a national framework saying which authority supervises what and how breaches are sanctioned. That gap was filled by the Law of 11 December 2025, published in the Belgian Official Gazette on 24 December 2025 and in force from 3 January 2026. It allocates powers between the FSMA and the NBB and turns MiCA into an enforceable national regime. From 3 January 2026, services such as custody, operating a trading platform, exchange, and portfolio management may no longer be provided from Belgium without complying with this supervisory framework.

The EU's revised Transfer of Funds Regulation (TFR) extends the "travel rule" to crypto transfers, and the EU Anti-Money Laundering Regulation (AMLR) tightens and harmonises AML duties. Fully decentralised protocols with no identifiable operator sit at the edge of MiCA. The European Commission opened a targeted consultation on the review of MiCA on 20 May 2026, under the mandate in Articles 140 and 142 of the regulation, which closes on 30 September 2026. Reporting on the consultation indicates it asks whether the framework should extend to areas such as decentralised finance, staking, lending and NFTs. Any change would come through the Commission report and, if warranted, a legislative proposal that follows it. Informational only, not legal advice; confirm current requirements with the FSMA and NBB.

Since 3 January 2026, providing crypto-asset services from Belgium requires authorisation as a CASP under the MiCA regime, with the FSMA as the principal authority. Authorised CASPs must meet both prudential rules (such as capital and governance requirements) and conduct rules (such as disclosure, custody safeguarding, and complaints handling).

MiCA includes a grandfathering window. Providers that were lawfully offering crypto services under an EU member state's national law before 30 December 2024 may continue to provide the same services until 1 July 2026, or until their CASP authorisation is granted or refused, whichever comes first. After that, only authorised CASPs may operate.

The rule of thumb is to use a provider authorised to serve EU customers under MiCA, which brings consumer-protection, custody, and disclosure standards, and to benefit from EU passporting. You can check a firm's status and any warnings on the FSMA website before sending money to a new platform.

Belgium's tax treatment of crypto changed materially in 2026, so older guides are often out of date. How a gain is taxed still depends partly on how you act as an investor, but a new general capital-gains tax now sits over the top.

From 1 January 2026, capital gains realised by private individuals on financial assets, explicitly including crypto-assets, are, as a rule, taxable at a flat rate of 10 percent. There is an annual exemption of EUR 10,000 per taxpayer (indexed), and an unused portion of that first tranche can be carried forward for up to five years, up to a maximum of EUR 1,000 per year, which can raise the exempt amount to EUR 15,000. A valuation as at 31 December 2025 acts as a "step-up" so that gains accrued before 2026 are not retroactively taxed. There is no withholding at source, so taxpayers must report gains themselves. The rates and exemptions are now fixed by the Law of 6 April 2026, published in the Moniteur belge on 21 April 2026, and the collection mechanics by the Royal Decree of 18 May 2026, published on 27 May 2026 and in force since 1 June 2026. Confirm how they apply to your own position with the SPF/FOD Finance or a Belgian tax adviser.

• Normal private management: a prudent private investor falls under the new 10 percent capital-gains regime, with the annual exemption.
• Speculative or frequent trading: where activity goes beyond normal wealth management, active short-term trading can instead be taxed as "miscellaneous income" at a flat rate of 33 percent.
• Professional activity: if trading or mining amounts to a professional occupation, profits are taxed as professional income at progressive rates, with possible social contributions.

Under the EU's DAC8 rules, crypto platforms increasingly report user data to tax authorities automatically, so assume the tax office can see activity on regulated exchanges. Keep detailed records (dates, amounts, euro values, fees, platform) for every buy, sell, swap, and reward. See our guide to crypto taxes. Informational only, not tax advice.

Crypto-asset service providers in Belgium are subject to strict anti-money-laundering and know-your-customer obligations, drawn from both Belgian and EU law.

• Identity verification (KYC): regulated platforms must verify your identity before you can trade or withdraw, typically requiring a government ID and proof of address. This is a legal AML requirement, not an optional check.
• Customer due diligence: Belgium's Anti-Money Laundering Act of 2017 requires firms to verify clients, assess the purpose of the relationship, and understand the source of funds, with enhanced due diligence for higher-risk clients such as politically exposed persons.
• EU harmonisation: the EU Anti-Money Laundering Regulation (AMLR) is shifting KYC from a one-off onboarding check toward continuous, risk-based monitoring.
• The travel rule: under the revised Transfer of Funds Regulation, in force since 30 December 2024, CASPs must collect and transmit identifying information about the sender and recipient of crypto transfers between regulated providers.

In practice, large or unusual transactions may trigger extra checks. Using an authorised provider that complies with these rules is the norm for legal access.

People in Belgium can buy crypto through international exchanges, brokers, regulated apps, and increasingly through banks. The practical steps on a regulated platform are straightforward:

• Choose a regulated provider authorised to serve EU customers under MiCA, and compare fees, supported assets, and how it custodies funds.
• Complete KYC by verifying your identity with a government ID and usually proof of address.
• Fund your account, most cheaply by SEPA bank transfer; cards are often supported but cost more.
• Buy, placing a one-off order or setting up recurring buys to average in over time.
• Decide on custody: leave assets on the platform for convenience, or withdraw to a personal wallet (a hardware wallet for larger amounts) to control your own keys. Self-custody is legal but places all security responsibility on you; back up your recovery phrase securely and never share it.
• Keep records of dates, amounts, and euro values for tax reporting.

Using crypto to pay merchants is permitted where the merchant chooses to accept it, but no business is obliged to. Bitcoin ATMs (crypto kiosks) exist only in small numbers, are themselves regulated, require identity verification, and typically charge far higher fees than an online platform.

Belgian banks are starting to offer crypto directly to retail customers under the MiCA framework. In February 2026, KBC, one of the country's largest banks, became the first Belgian bank to let retail customers buy and sell Bitcoin and Ether, offered through its Bolero online investment platform.

Bank-based access tends to come with limits that differ from a dedicated exchange. The KBC offering, for example, was launched on an execution-only basis (no investment advice), and was reported as a "closed-loop" service, meaning customers buy and sell within the platform rather than withdrawing coins to an external personal wallet. Customers were also required to complete a knowledge-and-experience test before trading, in line with investor-protection rules. If self-custody or a wider range of tokens matters to you, a dedicated MiCA-authorised exchange may suit better; if you value keeping the holding inside your existing bank, a bank offer can be simpler. Compare fees, the assets supported, and whether withdrawals to a personal wallet are allowed before choosing. This is not financial advice.

Mining cryptocurrency is legal in Belgium, but rarely competitive at scale because of high electricity prices. Proof-of-work mining is energy-intensive, so margins are thin compared with regions that have cheaper power, and energy-heavy computing sits awkwardly with Belgium's and the EU's climate priorities. There is no outright ban.

On tax, mining rewards are generally treated as taxable income at their euro value when received, and a serious, ongoing operation can be classified as a professional activity with extra obligations and possible social contributions. Anyone mining beyond a hobby scale should take tax advice and check the grid, permitting, and energy rules that apply to any energy-intensive business.

2026 is a pivotal year for crypto rules in Belgium.

• MiCA enforcement: the Law of 11 December 2025 came into force on 3 January 2026, giving Belgium a fully operational supervisory and enforcement framework and dividing powers between the FSMA and the NBB.
• Transitional window closed: grandfathering ended on 1 July 2026. In a notice of 25 June 2026 the FSMA confirmed that providers must hold a CASP authorisation as of that date, that without one they must cease offering these services in Europe, and that no CASP holds an authorisation granted by the FSMA in Belgium. Both FSMA registers carry a last verified date of 31 July 2026 and both read Nihil.
• New capital-gains tax: a general 10 percent capital-gains tax on financial assets, including crypto, applies to gains realised from 1 January 2026, with a EUR 10,000 annual exemption and a 31 December 2025 step-up valuation. The regime was finalised by the Law of 6 April 2026 and the Royal Decree of 18 May 2026. Withholding at source by Belgian banks, brokers and insurers has run since 1 June 2026, but EY's summary states that no withholding applies to crypto-assets, so crypto gains must be reported by the taxpayer.
• AML overhaul: the EU AML Regulation and the revised Transfer of Funds Regulation are tightening KYC and the travel rule across the bloc.
• Mainstream access: regulated, MiCA-compliant providers, including banks, are increasingly offering crypto buying and selling to Belgian retail customers. In February 2026, KBC became the first Belgian bank to offer direct Bitcoin and Ether trading to retail customers, through its Bolero online investment platform.

The direction of travel is toward clearer, harmonised, EU-wide rules with national enforcement on a firm footing.

Crypto in Belgium is now more clearly regulated, but it is not risk-free. The two biggest user risks are market volatility and fraud.

Common schemes include fake or "cloned" platforms that mimic real exchanges; investment scams promising guaranteed or unusually high returns, including Ponzi schemes and fraudulent token offerings; phishing messages and sites that capture your login or recovery phrase; and "pig butchering" or romance scams that build trust before pushing a fake investment.

Use only authorised providers, verify website addresses carefully, enable two-factor authentication, never share your seed phrase, and treat any unsolicited "opportunity" with suspicion. The FSMA publishes warnings about unauthorised firms and fraudulent platforms, and it is worth checking those lists before sending money anywhere new. Remember that prices are highly volatile and can fall substantially: a common conservative principle is to invest only money you can afford to lose. This is not financial advice.

Because crypto rules in Belgium are evolving, always confirm the current position with primary, official sources rather than secondary summaries. The most authoritative references are:

• FSMA - Crypto-Asset Service Provider (CASP) for licensing, the supervisory framework, and warnings about unauthorised firms.
• National Bank of Belgium for prudential and stablecoin supervision.
• SPF Finance / FOD Financien for tax rules, including the 2026 capital-gains regime.
• ESMA - Markets in Crypto-Assets Regulation (MiCA) for the EU-wide framework.
