When three companies that sell compliance infrastructure publicly ask to be taxed more, you should not applaud their civic virtue. You should ask who ends up holding the invoice.
On October 5, three French crypto executives did exactly this. Jean Meyer of Deblock, a licensed crypto neobank; Damien Patureaux of Lyzi, a merchant payment app; and Pierre Morizot of Waltio, a crypto tax-reporting tool, jointly proposed a direct tax on cryptocurrency and stablecoin exchanges. Their argument runs like this: the French treasury is bleeding revenue because users can swap Bitcoin into USDT or USDC without triggering a taxable event, and the state's infrastructure is too immature to catch it.
The proposal is elegant on paper. It is also a textbook case of what happens when the people who profit from complexity write the rules for it. The more closely you examine the execution layer, the more the civic framing dissolves.
To understand why this proposal exists at all, you need the shape of French crypto taxation. Under Article 150 VH bis of the Code gรฉnรฉral des impรดts, France taxes crypto capital gains only at two moments: conversion into fiat currency, or the purchase of goods and services. The rate is a flat 30 percent, bundling income tax with social contributions. Everything else โ Bitcoin to Ethereum, Ethereum to a stablecoin, a stablecoin to another stablecoin โ is invisible to the tax authority. No taxable event. No paperwork. No revenue.
That gap is the entire premise of the proposal. The founders frame it as leakage. Three firms look at a market where billions in value move between assets without ever touching the euro rail, and they see money the state cannot reach. Their remedy is to make the crypto-to-stablecoin swap itself a taxable event.
France has spent years building the scaffolding for this. The PSAN regime โ Prestataire de Services sur Actifs Numรฉriques โ licenses exchanges, custodians, and fiat gateways, forcing them into KYC and AML obligations. Above that sits the European layer: MiCA for market structure, DAC8 for crypto-asset reporting, and the OECD's CARF framework for cross-border information exchange. The direction of travel is unmistakable. Every major jurisdiction is converging on the same idea: crypto activity should be reported, attributed to a person, and taxed.
So the proposal is not radical. It is early. And that timing is precisely what makes it worth reading carefully โ not for what it says about France, but for what it reveals about who is steering the agenda.
Here is the technical problem the proposal cannot solve, and the founders know it.
A tax must be paid in a currency the state accepts. ADAN's Claire Balva made this point with surgical precision: the levy must be settled in euros, which means it can only be anchored at the fiat on-ramp and off-ramp. Not on-chain. Not inside the swap. Only at the point where value crosses the boundary between the crypto system and the banking system.
This is not a legal technicality. It is an architectural constraint. A Bitcoin-to-USDT swap executed on a decentralized exchange is borderless, permissionless, and identity-free. There is no counterparty to invoice, no jurisdiction to assert, no server to subpoena. You cannot tax a liquidity pool. You cannot garnish a smart contract. The only nodes in the entire system where a tax authority holds real leverage are the regulated ones: licensed centralized exchanges, custodial wallet providers, and fiat gateways.
So the proposal, whatever its framing, does not tax "crypto exchanges." It taxes regulated chokepoints. And that distinction changes everything about who wins and who loses.
If the swap becomes a taxable event, every compliant euro-denominated conversion is forced through infrastructure that can report it โ and every non-compliant, self-custodied, offshore swap simply continues, untouched.
This is the part of the debate that gets buried. The proposal does not capture the activity it claims to target. It captures the people who are already inside the fence.
I have spent enough time auditing contracts and sitting beside compliance teams to recognize this pattern. The rules that get written are rarely the rules that get enforced. What gets enforced is whatever is cheapest to enforce โ and the cheapest thing to enforce is always the honest user who has already handed over their identity. The sophisticated actor moves to a self-custodied wallet, swaps on-chain, and never appears in the data. The retail holder in Lyon, who keeps their USDC on a licensed platform because that is what feels safe, becomes the tax base.
This is the same theater I have watched play out across every KYC regime of the last five years. Compliance is not a wall. It is a toll booth on one road, and the road has a thousand lanes. The cost of the toll never lands on the people who can afford to take another route. It lands on the ones who cannot.
Code is not law; it is a negotiation. And in this negotiation, the party with the least leverage is the one already inside the system.
Now consider what ADAN's second warning actually means, because it is the most counterintuitive claim in the entire debate. Balva argued that taxing crypto-to-stablecoin swaps would push users toward USDT and other unregulated stablecoins. Read that again. The tax designed to close a revenue gap would, by its own internal logic, accelerate the migration of capital into the exact instruments that sit furthest beyond the state's reach.
The mechanism is simple once you see it. If swapping into a regulated stablecoin like USDC becomes a taxable event, then a user who wants to park value in dollars has a rational incentive to swap into a stablecoin that lives on a chain the tax authority cannot monitor. USDT's resistance to clean jurisdictional attribution โ long treated as a liability by regulators โ becomes a feature for the taxpayer. Regulation tightens, and the offshore stablecoin's relative appeal rises.
Regulatory friction does not eliminate the behavior it targets. It reprices it, and the repricing rewards the least transparent venues.
To make any of this enforceable, France would need something it does not have: a data reporting framework that attributes on-chain activity to real identities. DAC8 gestures at this, requiring crypto service providers to report user transactions to tax authorities. But DAC8 reports only what service providers can see. It says nothing about self-custodied wallets, decentralized exchanges, or cross-chain bridges โ the exact venues where the behavior the proposal targets actually occurs. You can mandate reporting for the visible layer. The invisible layer stays invisible by design.
Last year, while reviewing the reporting logic of a tax-automation tool for a small DeFi protocol, I watched it misclassify a single cross-chain bridge transfer as two separate disposals. The tool was not malicious. It was blind โ it could only see what the wallet told it, and the wallet could not see the other side of the bridge. This is the everyday reality of crypto taxation: not enforcement, but guesswork dressed as accounting. A law that declares every swap taxable does not create clarity. It creates a larger surface for exactly this kind of error, and the error always resolves in favor of the authority that writes the rulebook.
So the French proposal is best understood not as a tax measure but as a boundary-drawing exercise. It tries to define where the taxable world ends and the untaxable world begins, and in doing so it makes that boundary more valuable. Every line you draw creates a market for crossing it.
And here is the layer most observers will miss entirely. If this kind of framework advances โ whether through France alone or, more likely, through the EU's DAC8 and CARF machinery โ the largest structural winner is not the treasury. It is the compliant fiat gateway. Every taxable event gets funneled through infrastructure that can see it, report it, and charge for the privilege. The neobanks, the licensed gateways, the tax-reporting tools. The very firms that wrote the proposal.
Consider the incentives honestly. Waltio sells tax software. The more scenarios French law declares taxable, the more line items its product must handle, the more indispensable it becomes. Deblock sells compliant fiat on-ramps. The more conversions are forced through regulated channels, the more traffic arrives at its door. Lyzi sells merchant payment infrastructure. The clearer the tax rules around crypto payments, the easier it becomes to convince merchants to adopt them.
None of these are accusations of bad faith. They are descriptions of alignment. When a company's revenue grows in proportion to the complexity of the rules it helps navigate, its proposals about those rules deserve an asterisk. The civic framing โ "we must protect the treasury, we must simplify payments" โ is not false, exactly. It is simply indistinguishable from the commercial framing, which is the point.
Idealism without audit is just gambling. And a policy proposal is a claim that deserves an audit.
The tell is in the argument itself. The founders say clearer taxation will "simplify" crypto payments and encourage merchant adoption. But expanding the set of taxable events does not simplify anything. It adds friction, adds reporting, adds cost โ all of it landing on the user and the merchant. The word "simplify" is doing heavy lifting here, and it is carrying a payload the proposal never accounts for.
ADAN, notably, is the one voice in the room with no product to sell. Its stance โ that the levy can only function at the fiat layer, that it risks pushing users offshore, that it remains only a proposal โ is the most technically grounded position in the entire discussion. That is not a coincidence. It is the difference between a stakeholder and a beneficiary.
Zoom out, and the proposal collides with a harder reality: jurisdictional competition. France would be taxing swaps that Germany, Portugal, or Malta do not. Capital is mobile in a way that tax law is not, and the crypto holder in Nice can hold a wallet issued in Lisbon. A single country raising its take on a borderless asset class does not expand its tax base. It exports it. The European Commission understood this, which is why the real enforcement layer is DAC8 and CARF โ frameworks designed to remove the escape hatch by making every member state report to every other. France is not leading here. It is testing the water for a rule that only works if everyone plays.
So where does this leave us? Not with a tax. With a signal.
The proposal is not law. ADAN has confirmed the existing framework is unlikely to change in the near term, and no legislature has touched it. But the direction is written in the EU's reporting directives, in the OECD's framework, in the quiet convergence of every major jurisdiction on the same principle: that crypto value should be visible to the state.
The real question is not whether France will tax your stablecoin swap. It is who gets to define the boundary โ and whether the people drawing the map will be the same people selling the tolls. Trust no one, verify everything, build always. The proposal will be forgotten. The alignment behind it will not.
