What happens if your business doesn’t comply with MiCA?

Thousands of crypto companies across Europe are at a crossroads: continue operating under outdated VASP registrations or urgently adapt to the new MiCA framework. As of 2024, obtaining CASP status has become a core requirement for legally offering crypto services in the EU. But not all companies have managed to keep up — some underestimated the new obligations, others rely on transitional arrangements, and many remain unaware of the real risks. Meanwhile, non-compliance with MiCA can lead to severe consequences: from hefty fines and frozen accounts to reputational damage and market exit. In this article, we examine in detail the risks of failing to comply with MiCA, how EU regulators respond, and what companies can do to avoid legal and operational fallout.

What responsibilities does MiCA impose on a business?

The MiCA Regulation (EU Regulation 2023/1114) imposes extensive obligations on all companies providing crypto-asset-related services within the European Union. These requirements cover both licensing aspects and internal operations.

Who must comply with MiCA?

MiCA applies to all entities offering crypto services in the EU on a professional and ongoing basis. This includes both EU-based companies and third-country providers that target EU clients.  Under MiCA, a CASP (Crypto-Asset Service Provider) license is required for any company offering the following services:

• Custody and key management of crypto-assets;
• Execution of client orders;
• Exchange of crypto-assets for fiat or other crypto-assets;
• Reception and transmission of orders;
• Placement of crypto-assets;
• Portfolio management of crypto-assets;
• Provision of advice and personal recommendations related to crypto-assets.

Special attention is given to companies actively marketing in the EU, even if they are legally based outside of the Union. For example, a Singapore-based exchange offering custody or exchange services to French customers and promoting its services in French must obtain a CASP license.

What obligations does MiCA impose?

MiCA introduces strict requirements that span key operational areas:

1. Licensing: All CASPs must be authorized in an EU Member State, including formal registration, appointment of competent directors, and having a physical presence.
2. Corporate governance: Companies must maintain a transparent ownership structure, internal control systems, and designated officers responsible for compliance and AML.
3. Customer protection policies: CASPs are required to implement KYC/AML procedures, safeguard client funds, disclose key information, and warn of investment risks.
4. Cybersecurity and IT risk management: Articles 63–69 of MiCA mandate that CASPs put in place security protocols for IT systems, ensure operational continuity, and protect customer data.
5. Disclosure requirements: CASPs must publish a whitepaper when issuing tokens and keep investors informed of ongoing risks or material business changes.

Who enforces MiCA compliance?

Compliance with MiCA is overseen by national supervisory authorities in each EU Member State. These are typically central banks or financial regulatory bodies (such as the AMF in France, BaFin in Germany, and the Bank of Lithuania). These authorities are empowered to review submitted license applications, examine corporate documentation, conduct inspections, and impose penalties for violations.

Additionally, the EU Crypto Register is maintained as a public database listing all CASPs and the current status of their licenses, including any recorded breaches. Non-compliance with MiCA may result in removal from this register.

Sanctions for non-compliance with MiCA

MiCA establishes a clear legal framework for holding companies accountable when they fail to comply with its provisions. EU regulators have been granted powers to suspend non-compliant businesses and impose financial and administrative sanctions.

What sanctions are imposed under MiCA?

According to Article 111 of the MiCA Regulation, regulators may apply the following measures against entities that violate their obligations:

1. Financial penalties: up to €5,000,000 for natural persons and up to 12.5% of annual turnover for legal entities;
2. Temporary or permanent prohibition from offering crypto-asset services in the EU;
3. Removal from national and EU-wide registers, such as the EU Crypto Register;
4. Publication of violation details, leading to significant reputational risks;
5. Termination of cross-border operations, including the loss of passporting rights.

These sanctions apply both to companies operating without a CASP license and to those failing to meet the obligations after obtaining authorization.

What are the long-term consequences of MiCA non-compliance?

The broader impacts may go far beyond regulatory fines:

1. Loss of access to banking and payment infrastructure, including IBANs and SWIFT connectivity;
2. Termination of contracts with liquidity providers and technology partners;
3. Restrictions from marketplaces and exchanges that require full MiCA compliance from their participants;
4. Difficulty attracting investors and passing audits, especially during due diligence processes.

In effect, non-compliance with MiCA can lead to both legal and economic isolation of a crypto business within the EU market.

Which companies are under special scrutiny by regulators?

MiCA introduces heightened regulatory oversight for specific types of crypto companies whose activities pose increased risks to the financial system, investors, and the overall stability of the EU market. According to analytical materials published by the European Banking Authority (EBA) and the European Securities and Markets Authority (ESMA), the following types of entities are subject to enhanced scrutiny:

1. Platforms with a large user base — those serving over 1 million registered clients within the EU;
2. Custodial service providers managing crypto wallets and having access to clients’ private keys;
3. Major crypto exchanges, particularly those offering margin trading or derivatives on crypto-assets;
4. Stablecoin issuers, especially those offering tokens designed for widespread use (so-called significant asset-referenced tokens);
5. Companies dealing with anonymity-enhanced cryptocurrencies or high-risk transactions, such as in the DeFi sector;
6. Providers with a history of AML/KYC violations or previous sanctions within the EU.

These entities are required to submit more detailed documentation, undergo thorough vetting procedures, and may be subject to more frequent audits.

Enhanced reporting and compliance obligations

For companies falling under this category of increased regulatory attention, MiCA imposes the following requirements:

1. Regular reporting to national regulators, including data on client assets, internal controls, risk exposures, and financial statements;
2. Mandatory notifications regarding any material changes in the business model, company structure, or executive team;
3. Periodic inspections and audits, including unannounced supervisory visits;
4. Stricter cybersecurity and data protection standards, in line with MiCA Articles 63–69 and other EU digital resilience rules.

Failure to comply with these enhanced obligations may result in revocation of the CASP license, blacklisting in the EU Crypto Register, and in some cases, criminal liability.

Firms under enhanced supervision are strongly advised to develop a proactive MiCA compliance strategy. This includes assembling a professional compliance team, implementing robust internal audit systems, maintaining transparent reporting, and maintaining open channels with regulators at all stages of operation.

How do you minimize risk and be in full compliance with MiCA?

MiCA is not just a collection of rules — it is a new regulatory framework that reshapes how crypto businesses operate in the EU. Companies that want to avoid fines and remain competitive must proactively build a robust internal compliance infrastructure.

Implementing a full-scale internal control system

A key success factor under MiCA is the establishment of a comprehensive internal policy framework, including:

1. AML/CFT procedures that align with EU and FATF standards;
2. KYC policies and onboarding verification mechanisms;
3. Procedures for managing conflicts of interest;
4. Incident response plans for data breaches and cybersecurity threats;
5. Documentation for data backup, system access controls, and log retention.

Companies lacking these components are at high risk of license rejection or regulatory sanctions.

Appointing competent key personnel

MiCA requires all CASPs to appoint and maintain the following roles:

1. An executive director with proven experience in managing crypto-financial projects;
2. A compliance officer responsible for ensuring adherence to regulatory requirements;
3. An AML officer in charge of anti-money laundering and counter-terrorism financing controls.

All individuals must meet the MiCA standards of good repute and professional competence, which are subject to verification by national regulators.

Documenting all core business processes

To obtain and maintain a CASP license, a company must provide evidence of:

1. Revenue sources and a viable business model;
2. Ownership structure and identification of ultimate beneficial owners (UBOs);
3. Internal control systems and decision-making protocols;
4. Risk assessment methodology and mitigation strategies.

Proper documentation not only improves the chances of license approval but also reduces the risk of sanctions during audits or supervisory reviews.
