Deblock, Lyzi and Waltio chiefs ask France to tax swaps from crypto into stablecoins
Deblock, Lyzi and Waltio executives want France to tax crypto-to-stablecoin swaps, ending a 2019 rule that defers tax until holders cash out or spend. They argue the deferral leaves money parked in stablecoins and slows the build-out of French payment infrastructure.

What happened
- Taxing the conversion into a regulated stablecoin would, they contend, let later payments and bank withdrawals go through without a fresh gains calculation.
- In return they want gains computed asset by asset, as with shares, in place of portfolio-wide apportionment, with pure crypto-to-crypto trades left untaxed.
- They later clarified that the change would not raise the rate or tax a gain twice for people who already declare, and would mainly move the timing.
- Chainalysis estimates that more than 90% of France's crypto gains went undeclared, based on 2025 data.
- Claire Balva, general director of trade association ADAN, said it is still only a proposal and no changes to the regime are expected to pass.
Compiled by The InvestorSomething wrong?How this is made
Why it matters
- exposure Holders who never report a cash-out would face a taxable event at the swap itself, putting most of any new revenue on them instead of on declarers.
- constraint According to ADAN, taxing moves into regulated euro stablecoins would push users toward unregulated dollar tokens such as USDT, away from the tokens the proposal treats as tax-cleared money.
- decision Backers have to find lawmakers to carry the change as amendments in the 2027 budget debate, because the government has drafted no text.
Two of the three signatories run companies that sell electronic payment products for crypto and stablecoins [9], and the third, Waltio, sells tax-reporting software [1]. The ask suits both businesses. French rules make the taxpayer weigh the whole portfolio's acquisition cost and market value, then allocate a share of any unrealized gain to each disposal [16]. A small crypto purchase can therefore require a full portfolio calculation [16]. Patureaux described what that does at a shop counter. "When paying in crypto, customers ask merchants a lot of questions about taxation. We find ourselves doing after-sales service for the merchant's customer instead of making sales," he told Cryptoast [10].
In Le Monde the executives framed the deferral around agent-driven commerce settled largely in dollar- or euro-pegged tokens [3], and called it a "fiscal singularity that is paid for in missed revenue and unbuilt infrastructure" [11]. The revenue half rests on industry estimates, cited in their piece, of an annual budget shortfall in the low billions of euros [21]. Neither published account explains how that estimate was built.
Take the timing claim at face value [17]. On Chainalysis's estimate [19], the people who already declare account for less than a tenth of French crypto gains [20], so most of any new money would have to come from holders who report nothing today. Bitcoin.com expects higher collection alongside DAC8, the EU crypto data-sharing scheme France has joined, and a boom in individual tax statements [22]. Individual tax statements are Waltio's market [1]. Morizot said "the non-taxation of crypto/stablecoin transactions is a sword of Damocles" [18].
Balva's objection is practical [12]. Tax is paid in euros, so she argues it can only fall at the conversion to fiat [12]. Under the proposal, a holder who swaps bitcoin into a euro token would owe euros on a trade that produced none [12].
The 2019 rule stays if Balva's forecast holds [13]. The full proposal needs the swap tax to survive a budget fight in a split industry [7]. Some argue the crypto-to-crypto exemption is one of the regime's few favorable features and should not go without clear offsets [7]. A partial version would take the other concessions the executives listed, multi-year loss carry-forwards and a higher exemption threshold for small crypto payments [6], and leave the swap untaxed.
I think the partial version is the likelier of the two changes, because it gives merchants a simpler checkout without asking any holder to pay sooner. The counter-case is that the executives offered the asset-by-asset method in return for the swap tax [5]. Lawmakers looking for revenue have little reason to grant that relief without the collection point attached. An amendment that taxes the swap and wins ADAN's support would prove me wrong.
What to watch
- Any amendment tabled in France's 2027 budget debate that makes conversions into regulated stablecoins a taxable event.
- Publication of the industry estimate behind the claimed annual shortfall in the low billions of euros.
- Whether ADAN backs the asset-by-asset method and a higher small-payment exemption if they are offered without the swap tax.
