The future of tax mobility in a post-crypto world

1) Introduction — Mobility is changing: so must your playbook

What if mobility were no longer about passports and plane tickets, but about data? In 2025, private banks, notaries, and tax authorities don’t simply ask who you are and where you live—they receive that story automatically. The Common Reporting Standard (CRS) sends financial-account data to your residence jurisdiction every year; its crypto sibling, the OECD Crypto-Asset Reporting Framework (CARF), is rolling out with Global Forum guidance; and the EU’s DAC8 locks crypto into the same automatic-exchange ecosystem. In parallel, the EU Transfer of Funds Regulation (TFR) pushes the travel rule onto crypto so sender/beneficiary information moves with value, while MiCA licensing turns on/off-ramps into regulated rails. Mobility isn’t disappearing—it’s being measured. amf-france.org+4OECD+4OECD+4

On the immigration side, the last few years have rewritten the investment migration map. Programs once marketed as “golden visas” have been curtailed or reshaped—Portugal removed the real-estate route in 2023; Spain announced the end of its real-estate golden visa in 2024 and fixed the last deadline for applicants; and in 2025 the EU’s top court ordered Malta to shut down its citizenship-by-investment program. The direction of travel is clear: less asset-driven residency arbitrage, more substance-driven compliance. theguardian.com+4legal500.com+4ey.com+4

For globally mobile, crypto-native wealth, this new landscape is both a challenge and an opportunity. The challenge: mobility by spreadsheet (multi-flags, ad-hoc entities, opaque flows) no longer passes institutional screening. The opportunity: mobility by design—clear residency, regulated rails, audit-ready documentation—earns bank and notary confidence and unlocks predictable outcomes. In other words, future-proof mobility is compliance-led.

2) Defining “post-crypto” tax mobility — from passports to protocols

Post-crypto doesn’t mean “after crypto.” It means after crypto changed how value moves and how identity accompanies it. Three pillars define tax mobility now:

1. Automatic exchange is the default.
   • CRS: 100+ jurisdictions exchange account data annually (balances, income, proceeds). The 2025 consolidated CRS text confirms a modernized scope.
   • CARF: the Global Forum adopted step-by-step implementation in November 2024; expect standardized crypto-asset reporting across intermediaries.
   • DAC8: the EU’s framework for automatic exchange on crypto-asset transactions is adopted and moving into practice. Assume disclosure. Parlement Européen+3OECD+3OECD+3
2. Regulated rails carry identity with value.
   • MiCA: EU-wide licensing for CASPs, with phased application from 30 December 2024 and a transition window to 1 July 2026.
   • TFR (Reg. 2023/1113) + EBA guidelines (July 2024): crypto transfers between obliged entities must carry originator/beneficiary information; providers must detect missing data and block/exit non-compliant flows. Think SWIFT-grade metadata for blockchain. amf-france.org+3amf-france.org+3eur-lex.europa.eu+3
3. Investment migration is tightening, not vanishing.
   The EU’s pressure on CBI/RBI schemes continues. Portugal removed the real-estate path; Spain is eliminating the real-estate golden visa; Malta’s CBI was struck down by the ECJ. Expect future programs to prioritize substance (jobs, innovation, presence) over passive asset allocation. legal500.com+2lamoncloa.gob.es+2

Metaphor: If the 2010s were a wide-open highway for high-net-worth mobility, the 2020s are smart toll gates: you can still go fast—if your vehicle is registered, insured, and your papers are in order.

Key takeaway: Mobility strategies now hinge on residency clarity, entity substance, and documented provenance of funds—especially for crypto.

3) The new stakes — information flows, treaty access, and corporate floors

Information flows will find you. Under CRS, financial institutions determine your tax residency and report. Under CARF/DAC8, crypto platforms and custodians join that pipeline. The OECD’s 2024 update details the implementation trajectory; the 2025 consolidated CRS text underlines that AEOI is here to stay. If declared residency and reported residency diverge, expect mismatch letters and audits. OECD+1

Treaty access is residency-first. Double tax treaties confer benefits (lower withholding, capital-gains relief), but only if you are a resident of a contracting state under Article 4. Since 2017, the OECD Model’s tie-breaker for dual-resident companies relies on competent-authority agreement rather than a simple “place of effective management.” Practically, that means you should avoid dual claims by concentrating effective management in one jurisdiction—and documenting it. OECD+1

Corporate floors raise the waterline. Even if you’re perfectly mobile at the individual level, Pillar Two is reshaping corporate tax mobility for MNE groups (≥ €750m revenue). The EU’s 2022/2523 Directive applies from 2024 in the Union; the OECD’s 2025 administrative guidance and central record track qualified implementations worldwide. For families with operating businesses, the 15% minimum ETR narrows jurisdiction arbitrage and shifts the focus to real-economy substance and capital allocation.

Investment migration is no longer a tax shortcut. With the EU moving against CBI/RBI excesses—Spain’s real-estate route to end; Malta’s CBI struck down—mobility programs increasingly emphasize integration over investment-only. Mobility that relies on loopholes will age poorly; mobility that relies on law + evidence will endure. lamoncloa.gob.es+1

Analogy: The system is becoming tidal: information and minimums rise everywhere. Your job is to build higher piers—residency clarity, substance, regulated rails—so your plans stay dry.

4) Strategies that work — a mobility architecture built for scrutiny

1) Fix tax residency first (personal and corporate).

• Individuals: compile day-counts, housing/center-of-interest evidence, and, where relevant, certificates of residence. (If you claim France, align with CGI Art. 4 B; in the UK, the Statutory Residence Test; in the US, the Substantial Presence or treaty tie-breaker.)
• Companies: concentrate effective management (board meetings, officers, records, banking) in a single jurisdiction. Post-2017, dual-resident corporate cases require competent-authority MAP; design so you never need it. OECD

2) Choose regulated crypto rails.

• Use MiCA-aligned CASPs; if still in transition, verify the national regime and the 18-month MiCA bridge (to 1 July 2026) while authorization is processed.
• Ensure TFR travel-rule data accompanies crypto transfers; EBA guidelines (July 2024) tell providers to detect and handle missing data. Your file should match what CASPs share. amf-france.org+2eba.europa.eu+2

3) Build the four-stack dossier (before money moves).

• Identity & BO: passports, proof of address, organogram, control rights—kept accurate and current (FATF R.24/25 ethos).
• SoF/SoW: fiat statements & deal docs; for crypto—wallet statements, transaction hashes, platform ledgers, custodian attestations, conversion certificates.
• Governance: signed minutes/resolutions, local registers, officer appointments—on territory.
• Transactions: term sheets, escrow agreements, SWIFT/SEPA proofs, on-chain links, notarial deeds. When CRS/CARF/DAC8 reports land on a desk, your dossier should tell the same story. OECD

4) Map the jurisdiction matrix.
For you (residency), the entity (residency), the asset (situs), and the platform (regulator), chart: withholding, reporting (CRS/CARF/DAC8), and filing duties. This prevents mismatches—and surprises.

5) Assume investment migration 2.0.
Portugal’s and Spain’s reforms illustrate a new model: less property, more funds/innovation, more presence, more integration. If you chase labels (visa names), you’ll always be reactive; if you chase substance, you’ll be durable.
