France Advances 31.4% Crypto Tax Proposal, Raising Questions for Stablecoin Users
French cryptocurrency investors could soon face additional taxes when converting Bitcoin and other digital assets into stablecoins, following a parliamentary vote to change how such transactions are treated.
France’s National Assembly has approved an amendment that would make certain cryptocurrency-to-stablecoin conversions taxable events, potentially subjecting investment gains to the country’s 31.4% capital gains tax rate. The amendment could take effect in January 2027 if it survives the remaining legislative process.
However, the proposal has not yet become law.
What Is France Proposing?
The proposed change focuses on how cryptocurrency investors are taxed when swapping volatile assets such as Bitcoin or Ethereum for stablecoins.
Under the existing framework, certain crypto-to-crypto transactions generally benefit from tax deferral, meaning investors do not immediately pay capital gains tax until a taxable disposal occurs.
Stablecoins have traditionally played an important role in this arrangement.
For example, a trader could sell Bitcoin for a qualifying stablecoin rather than converting directly into euros, allowing them to preserve their position in the cryptocurrency market without immediately triggering the same tax treatment as a fiat conversion.
France’s proposed amendment, I-3898, would remove that deferral for certain stablecoins complying with the European Union’s Markets in Crypto-Assets Regulation (MiCA).
The proposal was narrowly approved by lawmakers, receiving 38 votes in favour, 37 against and 25 abstentions.
It must still pass the remaining stages of the 2027 budget process before taking effect.
How Could the 31.4% Crypto Tax Work?
The tax would apply to taxable capital gains, not necessarily the entire value of a cryptocurrency transaction.
Consider an investor who purchases Bitcoin for €10,000 and later exchanges it for €15,000 worth of qualifying stablecoins.
In a simplified example:
| Item | Amount |
|---|---|
| Bitcoin purchase price | €10,000 |
| Value when converted | €15,000 |
| Capital gain | €5,000 |
| Illustrative tax at 31.4% | €1,570 |
The actual tax calculation would depend on France’s applicable tax rules, the investor’s circumstances and the final wording of any legislation.
The significant change is that a trader could potentially face a tax obligation without first converting cryptocurrency into traditional money.
France Also Considers Self-Custody Wallet Reporting
The stablecoin tax proposal is not the only cryptocurrency measure under discussion.
According to Cointelegraph’s reporting, French lawmakers are separately considering additional requirements affecting cryptocurrency holders.
One proposal would require individuals with more than €100,000 in qualifying self-custody wallet holdings to declare those assets to tax authorities.
Another would expand France’s exit tax framework to certain cryptocurrency holders with portfolios exceeding €800,000 when transferring their tax residence abroad.
Neither measure should be treated as an enacted requirement at this stage.
They remain separate legislative proposals and could be amended, rejected or delayed.
Why Are Stablecoin Users Concerned?
Stablecoins such as USDC and USDT are widely used by cryptocurrency traders to reduce exposure to sudden price movements.
For example, someone expecting Bitcoin to fall might sell BTC for a dollar-backed stablecoin and later buy Bitcoin again when prices appear more attractive.
If such conversions become taxable, investors could face additional reporting obligations and potentially earlier tax payments.
Critics also argue that the changes could make trading through regulated European platforms less attractive.
However, the tax consequences of using offshore exchanges or decentralised finance platforms would still depend on French tax law. Moving trading activity outside France would not automatically remove a French taxpayer’s obligations.
What Could This Mean for African Crypto Markets?
Although the proposed rules concern France, they contribute to a wider debate about how governments should tax cryptocurrencies.
In Africa, countries including Kenya, Nigeria and South Africa are developing different approaches to digital asset regulation and taxation.
Stablecoins are also increasingly used for trading, cross-border payments and storing dollar-denominated value.
France’s proposal illustrates how regulatory treatment can affect not only cryptocurrency investments but also the practical use of stablecoins.
For African policymakers, the broader question is how to collect appropriate taxes without unnecessarily complicating digital payments or discouraging compliant businesses.
Blockwisely Take
France’s proposed tax amendment highlights a challenge facing cryptocurrency regulators: should exchanging one digital asset for another trigger tax immediately, even when no traditional money changes hands?
From a tax authority’s perspective, taxing realised investment gains can support consistent treatment across different assets.
For traders, however, requiring tax payments on stablecoin conversions could introduce additional costs, recordkeeping obligations and liquidity challenges.
The final implications will depend on how the proposal develops through France’s legislative process.
For now, investors should distinguish between an amendment approved by lawmakers and a tax rule that is actually in force.
Frequently Asked Questions
Has France introduced a 31.4% tax on all stablecoin transactions?
No. Lawmakers have advanced a proposal concerning capital gains from certain cryptocurrency-to-stablecoin conversions. It has not yet become final law.
Would the tax apply to the full value of a Bitcoin sale?
Generally, the proposal concerns taxable gains rather than automatically taxing the full transaction value.
When could the new rules take effect?
The proposed start date is January 2027, subject to final legislative approval.
Is France banning self-custody wallets?
No. A separate proposal concerns reporting certain large self-custody holdings. It is not a blanket ban on owning personal cryptocurrency wallets.
Does the proposal affect cryptocurrency investors in Africa?
It primarily concerns people subject to French taxation. Its broader relevance lies in how other jurisdictions may approach stablecoin taxation.
