MiCA vs National Regulations: What Changes for Existing Licensees

If your firm already holds a national VASP registration in an EU Member State, the Markets in Crypto-Assets Regulation did not switch you off overnight, but it did not leave you alone forever either. MiCA replaces the patchwork of national crypto regimes with a single EU framework built around a Crypto-Asset Service Provider (CASP) authorisation. For a firm that was authorised under national law, the question was never "if" but "by when": the national licence bought a time-limited bridge that closed on 1 July 2026 at the latest, and a full MiCA CASP authorisation is the destination. This page explains, from the actual instrument, exactly what changes, how long the bridge lasted, and what you must upgrade to keep serving clients in the EU.

Does MiCA replace my national crypto licence? (answer-first)

MiCA applies fully to crypto-asset service providers from 30 December 2024. If you were already providing crypto-asset services under applicable national law before that date, you were not shut off at once. Article 143(3) let you keep operating during a transitional grandfathering window, but only until your Member State's deadline, at most 1 July 2026. That date has passed, so a full MiCA CASP authorisation is now mandatory.

So MiCA does replace your national authorisation, in the sense that the national VASP regime ceases to be the basis on which you can serve EU clients. What it does not do is grandfather you indefinitely. MiCA harmonises the rules for CASPs and crypto-asset issuers across all 27 Member States, while some national procedural and AML elements continued to apply during the transition. The practical reading for a firm already in the market was straightforward: the national registration was a countdown clock, and the upgrade to CASP authorisation had to be completed before it ran out. For the wider framework, see the full MiCA regulation guide.

The short answer for grandfathered firms

Your national licence kept working only until your country's transitional deadline, and never later than 1 July 2026. The window also closed earlier if your competent authority granted or refused your MiCA authorisation before the cap. In short, the grandfathering period was a bridge, not a renewal. The day your window ended was the day you either held full MiCA CASP authorisation or stopped providing crypto-asset services in that Member State. There is no automatic conversion of a national VASP registration into a MiCA CASP authorisation.

National regulation vs MiCA CASP authorisation at a glance

A national VASP registration and a MiCA CASP authorisation are different instruments with different reach. The table below contrasts the two on the dimensions that matter for a firm deciding how much work the transition involves. For the entity-level distinction behind these labels, see VASP vs CASP under MiCA.

This contrast is why a national VASP licence rarely satisfies MiCA on its own. The supervisor stays national, but the substantive bar rises to the EU-wide standard.

What is the MiCA grandfathering period under Article 143(3)?

The grandfathering period is the transitional mechanism in MiCA Article 143(3) that lets firms already authorised under national law keep operating after MiCA starts applying to CASPs. It ran for up to 18 months from 30 December 2024, ending no later than 1 July 2026, and Member States could shorten it, producing a range of 6 to 18 months.

This is the most misunderstood part of the regime. The 18-month maximum is a ceiling, not a guarantee. The actual duration depended on what your home Member State decided, and several states chose materially shorter windows. The clock also stopped the moment your competent authority granted or refused your MiCA authorisation, whichever came first. The MiCA key dates and transition periods page sets out the full calendar.

How the transitional window worked

The Article 143(3) mechanics are easiest to read as a short sequence:

• MiCA applies fully to CASPs from 30 December 2024, when the grandfathering clock started.
• Firms already providing services under applicable national law before that date could keep operating during the window.
• The window was capped at a maximum of 18 months, ending no later than 1 July 2026.
• It ended earlier if the firm was granted or refused MiCA authorisation before the cap, whichever was sooner.
• Member States could shorten or switch off the window, so the real deadline was country-specific.

Why Member States can shorten the window

National competent authorities (NCAs) were given discretion to reduce the 18-month period or decline to offer it, typically where the existing national VASP framework was considered less strict, or simply where the authority wanted firms to migrate to the MiCA standard faster. This is the structural reason deadlines differ so much across the EU: the same regulation, applied through 27 different national decisions. The consequence for an existing licensee was that the 1 July 2026 cap could not be assumed: in several countries the door closed well before the maximum.

When did my grandfathering window end? (deadlines by Member State)

Your grandfathering deadline depended entirely on your home Member State. ESMA publishes the official per-country list under Article 143(3), and the dates diverged sharply: the six-month states, the Netherlands among them, closed first, Germany and Austria ran to the end of 2025, and only firms in states that took the full window reached the 1 July 2026 cap.

Grandfathering deadlines by Member State (table)

The rows below combine ESMA's official Article 143(3) list with the national transitional rules. The periods for the other Member States follow the table.

The spread is real money and real risk. A Dutch-registered firm had six months from the start of MiCA's CASP application, to 30 June 2025; a firm relying on the full cap had until 1 July 2026.

Countries not in the table: ESMA's list

ESMA's official Article 143(3) list covers all 27 Member States, and none of them disapplied the regime. In the May 2026 version, the periods are 6 months in Latvia, Hungary, Poland, Slovenia and Finland (alongside the Netherlands); 9 months in Sweden; 12 months in Ireland, Lithuania and Slovakia (alongside Germany and Austria); and 18 months in Belgium, Bulgaria, Czechia, Denmark, Estonia, Greece, Spain, France, Croatia, Cyprus, Luxembourg, Malta, Portugal and Romania (alongside Italy). Denmark, Czechia and Bulgaria tied the benefit to an application date (30 December 2024, 31 July 2025 and 8 October 2025 respectively). Poland's six months were never enacted: its crypto-asset market act did not pass, and the Polish register authority treated the transitional period as expiring on 1 July 2026.

What is the simplified authorisation procedure (Article 143(6))?

MiCA Article 143(6) permits, but does not require, a Member State to run a lighter authorisation procedure for entities already authorised under national law before 30 December 2024. It was a national option, applied unevenly. Germany offered it under § 50(3) of the Kryptomärkteaufsichtsgesetz (KMAG) and the implementing Kryptomärktezulassungsüberführungs-Verordnung (KMZÜV). The procedure mainly reduces duplicated documentation the NCA already holds; it does not lower the substantive MiCA bar.

Which countries offer the simplified procedure

Germany offers the simplified route via BaFin, which treats existing KWG-licensed institutions through a gap analysis of KWG against MiCA requirements. The window for filing under Article 143(6) closed on 1 July 2026. The presence or absence of this option changed sequencing materially, because a simplified procedure can shorten the documentation burden even though it does not change what you must ultimately prove.

"Simplified" does not mean automatic

Even where a simplified procedure was available, it was not an automatic conversion. The firm still filed an application with its NCA and had to demonstrate full MiCA conformity across capital, governance, client-asset safeguarding and conduct. What "simplified" reduced was the re-submission of material the authority already held from the national authorisation; it did not waive the substantive obligations of MiCA Titles II to V.

No transition for firms not licensed before 30 December 2024

There is a hard cut-off that the grandfathering regime does not soften. If your firm was not authorised under applicable national law before 30 December 2024, you get no transitional regime at all. You cannot rely on a national VASP registration obtained after that date as a bridge, because the bridge only exists for firms already in the market when MiCA began applying to CASPs.

What newcomers must do instead

A firm without a pre-30-December-2024 national authorisation must obtain full MiCA CASP authorisation up front, before providing any crypto-asset services in the EU. There is no operating-while-applying allowance for newcomers. The practical route is the standard MiCA application: build to the full Title II to V standard from day one, then file with your home Member State NCA. For the end-to-end process, see how to get a CASP authorisation.

What new requirements does MiCA add beyond a national licence?

This is the substance of "what changes." MiCA Titles II to V impose a harmonised set of obligations that most national VASP regimes did not fully cover, and the gap between a national registration and a CASP authorisation is exactly this list. The headline is capital: MiCA ties a minimum own-funds floor to your CASP service class through its Annex IV tiers. The rest of the uplift covers governance, client-asset safeguarding, conduct, ICT resilience and, for issuers, white papers. For the firm-level building blocks behind these obligations, see national VASP licensing.

Own-funds and capital floors

MiCA sets a minimum capital floor tied to the CASP service class you operate, through the Annex IV tiers referenced in the authorisation rules. For most national VASP holders this is a genuine uplift, because national capital requirements were often lighter than the MiCA floor.

Governance, fit-and-proper and outsourcing

MiCA requires demonstrable management-body suitability, a shareholder and qualifying-holding assessment, a documented conflicts-of-interest policy, and controls over outsourcing arrangements. A firm that satisfied a lighter national fit-and-proper test will usually need to rebuild its governance file to MiCA's standard, including evidence on each board and senior member.

Client-asset safeguarding and prudential rules

MiCA imposes segregation of client crypto-assets and client funds from the firm's own, with custody and safekeeping obligations for firms holding assets on behalf of clients. This is one of the most operationally demanding upgrades, because it touches wallet architecture, banking arrangements and reconciliation processes, not just paperwork.

Conduct, disclosure and complaints

MiCA applies an honest, fair and professional conduct duty toward clients, with transparent fee and risk disclosures and a formal complaints-handling process. Existing licensees often have the commercial elements but lack the documented, MiCA-aligned disclosure and complaints frameworks the regulation expects to see evidenced.

ICT resilience (DORA) and operational continuity

MiCA-authorised firms must run business-continuity and ICT risk-management arrangements, aligned with the EU Digital Operational Resilience Act (DORA), and maintain the security of their systems. For many crypto firms this is a substantial programme covering incident management, third-party ICT risk and resilience testing, well beyond what national VASP registration required.

AML/CFT and the Travel Rule

Full AML and KYC obligations apply, including Travel Rule compliance for crypto-asset transfers. This is the area of greatest continuity, since most national VASP regimes were AML-driven, but MiCA layers it onto the broader prudential and conduct framework rather than treating AML as the whole of compliance. For the underlying programme, see the crypto compliance AML and KYC guide.

White papers: issuers, not every grandfathered VASP

A point the old guidance blurred: the MiCA white-paper regime applies to issuers of asset-referenced tokens (ARTs), e-money tokens (EMTs) and other crypto-assets, not to every grandfathered service provider. Mandatory white-paper content, notification and liability rules are an issuer obligation. If your firm only provides services and does not issue tokens, the white-paper rules are not your direct burden, though they may affect the assets you list.

Can I passport across the EU during the transition?

No. During grandfathering, a firm operated only under its home national authorisation, and the MiCA single-licence passport that lets a CASP serve clients across other Member States is unlocked only on full MiCA authorisation.

Home-state-only operation during grandfathering

In practice this meant a grandfathered firm could not lawfully extend its national footprint into other Member States on the strength of the transitional regime. Cross-border expansion was one of the strongest commercial reasons to prioritise full authorisation rather than ride the grandfathering window to its end. To understand how the EU-wide right works once granted, see single EU licence passporting.

How to move from a national VASP registration to a MiCA CASP authorisation

The transition is a project, not a form. The path below sequences the work so you reach an application that an NCA can grant. The order matters: do the analysis first, fix the substance second, file last.

Step 1: Run a MiCA gap analysis

Map your national-licence coverage against MiCA Titles II to V and identify the deltas: where capital, governance, client-asset safeguarding, conduct, ICT and AML fall short of the MiCA standard for your service class. The output is a prioritised remediation list with a realistic timeline.

Step 2: Upgrade capital, governance and policies

Close the gaps. Raise own-funds to the relevant Annex IV tier, rebuild governance and fit-and-proper files, implement client-asset segregation, align ICT and continuity with DORA, and bring AML and conduct frameworks to the MiCA standard. This is the longest stage and should start the moment the gap analysis is done.

Step 3: File with your NCA

Submit the CASP application to your home NCA. The transitional windows and the simplified procedure closed on 1 July 2026, so a firm that has not yet filed applies under the ordinary Article 62 and 63 procedure and may not provide crypto-asset services until it is authorised.

Does MiCA affect Swiss firms with a national licence?

Switzerland sits outside MiCA. A Swiss firm holding a FINMA-related authorisation is regulated under Swiss law, not the EU framework. But the geographic test in MiCA is about where the service is provided, not only where the firm is based, so a Swiss firm targeting EU clients can fall within MiCA's scope for those specific services.

Switzerland is outside MiCA but EU-facing services are not

If a Swiss-regulated firm actively serves clients in the EU, it generally needs MiCA CASP authorisation for those EU-facing services, alongside its Swiss authorisation for its Swiss activity. This is a common situation for Crypto Valley firms expanding into the single market, and it turns on the VASP-to-CASP distinction rather than on the firm's home regulator. From our practice in Zug, the firms that manage this best treat EU expansion as a separate authorisation project from the outset rather than assuming Swiss status carries over. We have repeatedly seen that early gap analysis is what separates a clean MiCA application from a scramble against the deadline.

Limitations and scope

This page covers what changes when a firm holding a national VASP registration moves to full MiCA CASP authorisation: the grandfathering mechanism, the simplified procedure and the substantive obligations gap. It does not cover the requirements for a firm applying from scratch, see how to get a CASP authorisation, or the full EU-wide calendar, covered in MiCA key dates and transition periods.

• The deadline table gives end dates for the Netherlands, Germany, Austria and Italy; the periods of the other Member States follow ESMA's Article 143(3) list.
• Grandfathering windows ranged from 6 to 18 months and depended on each Member State's own decision, not the 1 July 2026 EU-wide cap alone.
• The Annex IV own-funds tiers are EUR 50,000 (Class 1), EUR 125,000 (Class 2) and EUR 150,000 (Class 3), or one quarter of the previous year's fixed overheads if higher (Art. 67(1)).
