MiCA's grandfathering window closes on 1 July 2026. That is the hard deadline in Article 143(3) of the Markets in Crypto-Assets Regulation (Regulation (EU) 2023/1114): crypto businesses operating under old national regimes must hold — or have applied for — a CASP authorisation to keep serving EU clients after it. Because the authorisation itself takes months and BaFin-style assessment runs to a statutory 40 working days from a complete application (Art. 63), the practical runway is already short. This is what is changing, who is affected, and how to prepare.
What is changing
MiCA replaced a patchwork of national crypto registrations with a single EU regime. Member states were allowed a transitional period during which firms authorised under prior national law could continue while converting to a CASP authorisation. Article 143(3) sets the outer limit of that transition at 1 July 2026. After that date, the transitional cover falls away: providing crypto-asset services in the EU requires a CASP authorisation, full stop.
Two related obligations bite at the same time. CASP own-funds must meet the Article 67 thresholds — €50,000, €125,000 or €150,000 by service class, with a floor of at least a quarter of prior-year fixed overheads. And DORA, the EU's digital operational resilience regime, has applied since 17 January 2025, so the conversion dossier must show resilient ICT and third-party risk management, not just financial and AML controls.
Who is affected
- Legacy national registrants — firms that registered under pre-MiCA national regimes and have not yet converted are most exposed.
- Firms relying on a shortened transition — several member states set transition periods ending before the 1 July 2026 outer limit; the binding date can be earlier than firms assume.
- Groups passporting from one base — if your EEA access depends on a single authorisation, a delay in that member state stalls the whole group.
- Non-EU firms serving EU clients — reverse-solicitation is narrow; serving EU customers generally needs authorisation.
How to prepare
- Confirm your real deadline. Check the transition end-date in your member state, not just the 1 July 2026 outer limit.
- Scope CASP services. Fix which services you provide; this sets the Article 67 capital class and the conduct rules.
- Close the capital gap. Test own-funds against both the class amount and the fixed-overheads floor.
- Build the dossier. Governance, AML/CFT, custody, and DORA-compliant operational resilience, with a financial plan.
- File early. The statutory clock only starts on a complete application; an incomplete filing resets it.
Member-state variation
MiCA is a single regulation, but the transition is not uniform. Member states were permitted to set their own transitional periods up to the 1 July 2026 outer limit, and several chose shorter windows — so a firm registered in one country may face an earlier cut-off than a competitor next door. National competent authorities also differ in practice on processing speed, documentary expectations and how strictly they read substance requirements, even though the statutory assessment clock (40 working days from a complete application) is common to all. The lesson is to plan against your specific member state's rule, not the headline EU date.
Cost implications
Conversion has three cost layers. First, capital: meeting the Article 67 own-funds floor — the higher of the class amount and a quarter of prior-year fixed overheads — can require a top-up for firms that previously operated on thinner capital. Second, build cost: a complete, DORA-ready dossier with resourced compliance and risk functions. Third, ongoing cost: supervision, reporting and the operational-resilience obligations that continue once authorised. Firms that budget only for the application fee and discover the capital and resilience costs late are the ones that miss the deadline. A useful discipline is to model the conversion as a project with its own budget and owner, gated against the member-state deadline, rather than folding it into business-as-usual compliance where it competes for attention and slips.
What it means commercially
The deadline is also an opportunity. Conversion forces a decision about your EEA base — and a CASP authorisation passports across the EEA, so the member state you choose to anchor in matters for credibility, banking and supervision. Firms that treat the deadline as a structuring decision, rather than a compliance chore, come out with a cleaner footprint.

FAQ
What is the MiCA grandfathering deadline?
1 July 2026 is the outer limit set by Article 143(3). Several member states apply shorter transition periods, so confirm the date that binds you.
What happens if we miss it?
Without a CASP authorisation (or a pending application under the applicable transitional rule), continuing to provide crypto-asset services to EU clients is no longer permitted after the transition ends.
How long does conversion take?
Plan in months. BaFin-style assessment is a statutory 40 working days from a complete application (Art. 63), but assembling a complete, DORA-ready dossier is the longer part.
