France has taken a significant step toward pulling self-custodied cryptocurrency holdings into its regulatory orbit, approving an amendment that would compel taxpayers to disclose crypto assets held in private wallets when those holdings reach or exceed 100,000 euros — roughly $112,000 at current exchange rates. The move signals an escalating determination among European governments to close what regulators increasingly view as a visibility gap: the trillions of dollars in digital assets held outside of licensed exchanges and custodians, largely invisible to tax authorities.
The amendment, which cleared an initial legislative hurdle in France's National Assembly, is not yet law. It must still survive the broader budget process — a gauntlet that in French politics can be unforgiving, particularly for provisions that touch personal financial privacy. That caveat matters. Many a targeted tax measure has entered the French budget debate with momentum only to be stripped out, watered down, or delayed during committee negotiations. Supporters of the amendment would do well not to treat its current passage as a fait accompli.
Still, the political direction is unmistakable. For years, European regulators wrestled with the challenge of exchange-based crypto activity, ultimately producing frameworks like the Markets in Crypto-Assets Regulation (MiCA) to bring custodial platforms to heel. Self-custodied wallets — hardware devices, software wallets, paper keys — remained a deliberate blind spot. The French amendment represents one of the more concrete legislative attempts within the European Union to address that gap at the individual taxpayer level, rather than purely at the platform level.
The €100,000 threshold is not incidental. It is calibrated to target holders of meaningful wealth in crypto, not casual retail participants dabbling with a few hundred euros in Bitcoin or Ethereum. At $112,000, the threshold would capture serious investors, early adopters who have held through multiple cycles, and high-net-worth individuals who have opted for self-custody precisely to maintain control and privacy over their assets. For this cohort, the reporting requirement would represent a meaningful new compliance obligation — and, critics would argue, a meaningful new surveillance mechanism.
The privacy dimension cannot be dismissed. Self-custody exists for many reasons: security against exchange hacks, philosophical alignment with crypto's decentralized ethos, and in some cases, simple preference for personal financial control. The French amendment does not criminalize self-custody, nor does it propose to confiscate assets or impose new taxes beyond existing capital gains frameworks. What it does do is require disclosure — the act of informing the state that these holdings exist. For many in the crypto community, that distinction will feel thin. Disclosure requirements are frequently the precursor to more aggressive regulatory action, and the precedent set by France, within the EU's broader regulatory architecture, could embolden similar measures across the bloc.
The practical enforcement challenge is also worth examining. Unlike exchange-held assets, where platforms can be compelled to report customer balances directly to tax authorities — as Coinbase and other licensed custodians are required to do in multiple jurisdictions — self-custodied wallets are, by design, opaque. A taxpayer who chooses not to disclose a hardware wallet holding €150,000 in crypto faces detection risk primarily through on-chain analysis or cross-referencing with exchange withdrawal records. French tax authorities would need substantial technical capacity and investigative resources to enforce the rule meaningfully against determined non-compliers. The amendment's deterrent value may ultimately exceed its enforcement reach.
What France is really doing here is staking out a normative position: that crypto wealth, wherever it is held, is not exempt from the obligations that govern other forms of personal wealth. That position is gaining ground across the developed world. The United States has pursued crypto reporting through broker reporting rules and Foreign Bank and Financial Accounts (FBAR)-adjacent mechanisms. The United Kingdom has signaled similar intentions. France, historically more interventionist in financial matters, is now joining that chorus with specific legislative language targeting the self-custody tier.
The amendment's fate in the budget process will be closely watched — not just in Paris, but in Brussels, Berlin, and among the crypto industry lobbying groups that have made self-custody protections a central policy priority. If it survives and becomes law, France will have established one of the EU's first explicit self-custody reporting thresholds, creating a template that others may follow. If it is stripped out, it will likely return in a future budget cycle, perhaps with a lower threshold or broader scope. Either way, the direction of travel is clear: Europe's governments are no longer content to treat private wallets as beyond their reach.
