Taxation of Tokenized Stocks and Crypto Derivatives in France

You buy a token that tracks the price of Apple on the blockchain. You open a leveraged position on the SP500 from a crypto platform. The action is simple, quick, almost trivial. Yet, behind this click lies a daunting question that trips up the vast majority of investors: in the eyes of the French tax authorities, what do you actually own?

Beware, the trap is insidious. The tax rate is the same everywhere (31.4% since 2026). So, it is tempting to think: << After all, it doesn't matter which box, it's the same percentage! >> Fatal mistake. Because while the rate does not change, everything else (the rules for calculating capital gains, the possibility of deducting your losses, and even the form to fill out) differs completely. Ignoring this distinction risks paying too much tax, or worse, finding yourself at odds with the administration.

To clarify things, we propose to demystify this puzzle together. Forget the obscure jargon and incomprehensible legal texts. We will try to categorize things simply so that everyone can see more clearly. Let's go.

The Starting Point: Three Categories, Not One

The French tax administration does not classify assets based on the platform where you buy them, nor based on the price they track. It classifies them according to their legal nature. There are three categories.

• Category 1: Crypto-assets. You hold a fungible token, interchangeable with another identical one: one bitcoin is worth one bitcoin. Regime: Article 150 VH bis of the General Tax Code.

• Category 2: Securities. You hold a security: a stock, an ETF, a bond, or a certificate issued by a company. You have a right over something or someone. Regime: Article 150-0 A.

• Category 3: Financial Contracts. You own nothing at all. You have signed a contract with a platform, whose value depends on the price of another asset. Regime: Article 150 ter. These are also referred to as << derivatives >>, because their value derives from that of something else.

The whole issue is to determine which category your product falls into.

The Same Rate That Lulls Vigilance

Since January 1, 2026, the flat tax (the << flat tax >>) has increased from 30% to 31.4%. It breaks down into 12.8% income tax (unchanged) and 18.6% social contributions (up from 17.2% previously), in accordance with the 2026 Social Security financing law.

This rate of 31.4% applies to the three categories mentioned above. Hence the very widespread and very erroneous conclusion that classification does not matter.

But it does matter significantly, because the calculation rules have nothing to do with it.

In the Crypto Category: Exchanges Are Neutral

Converting bitcoin to ether (or any other cryptocurrency, including stablecoins) does not trigger any tax. The operation is called << intercalary >>: the tax authorities consider that you have not realized any gains. Tax is only triggered when you convert back to fiat currency (euros, dollars) or when you purchase a good or service with your cryptos.

There is also a threshold: if the total of your disposals in the year does not exceed 305 euros, you are exempted.

On the other hand, a loss that you do not use within the year is definitively lost. No carryover is possible.

In the securities category: every sale counts

Here, there is no neutrality. Every transfer is taxable, even if you are paid in something other than euros. There is also no exemption threshold.

The counterpart is a substantial advantage: your losses offset your gains of the same nature for the year, then for the following ten years. A bad year is no longer lost.

In the derivatives category: we do not look through

This is the least intuitive point and the one that causes the most errors.

For a derivative product, the underlying does not determine the tax category. A contract that tracks the price of Apple and a contract that tracks the price of bitcoin fall into the same box because what you hold, in both cases, is a contract. The underlying only serves to set the price.

The calculation is also particular: it is not << selling price minus purchase price >>, but the difference between the amounts received and the amounts paid, on a weighted average price if you have traded multiple identical contracts, and net of fees and taxes. Commissions and financing fees are therefore deducted.

Beware of a rarely mentioned point: when the account holder or the counterparty is established in a non-cooperative state or territory as defined by Article 238-0 A of the CGI, the rate rises to 50%. If you use platforms operating from exotic jurisdictions, verification is essential.

Where do tokenized stocks fall?

The expression can be misleading. A << tokenized stock >> is almost never a stock. The products offered by exchange platforms (like Kraken's xStocks, for example) are tracker certificates issued by a company, backed 1:1 by real stocks held by a custodian. You benefit from an economic exposure to the price of the underlying stock, but you are not a shareholder: no direct voting rights, no cash dividends (they are automatically reinvested in additional tokens), and no legal claim on the underlying shares. (Since August 2026, a mechanism allows for proxy voting at Kraken.)

These characteristics place them in category 2, that of securities. The text almost explicitly states this: Article 150 VH bis excludes tokens with the characteristics of financial instruments from the crypto regime.

And the boundary has recently tightened further. The law of June 25, 2026, against social and tax fraud has restricted the crypto regime, for sales made since January 1, 2026, to only crypto-assets falling under the European regulation MiCA, which expressly excludes financial instruments. The same text creates a regime for non-fungible tokens (NFTs), taxed according to the nature of the asset they represent. The legislator thus assumes a logic of transparency: for a backed token, we look through the packaging.

An important reserve: the qualification of a token as a security depends on its precise legal structure. Not all tokens backed by shares are necessarily financial securities within the meaning of Article L 211-1 of the Monetary and Financial Code. A case-by-case analysis remains necessary.

Where do equity derivatives fall?

This is the question that comes up most often, and the answer is surprising.

Some platforms offer perpetual contracts on stocks and ETFs, with no expiration date, featuring a funding rate mechanism to maintain alignment with the spot price. Others offer futures contracts with a maturity date, such as OKX's X-Perps (their commercial name is misleading: they expire after five years, so they are not perpetual).

In both cases, the marketing vocabulary sometimes refers to products as "backed by" shares. This is inaccurate: nothing is owned, nothing is reserved. The contract is a pure derivative, settled in cash or stablecoin (note that this can also change everything from a tax perspective), which follows the economic performance of the underlying asset without ever transferring ownership. The only technical difference (the absence or presence of an expiration date) has no tax implications.

These products therefore fall into category 3, that of financial contracts, and not into that of securities, even when they track the S&P 500 or Nvidia. Perpetual or futures: the box is the same.

Beware of the settlement method

If the contract is settled in stablecoin, receiving a digital asset as settlement may have additional reporting consequences. The digital asset account on which you receive the stablecoins must be declared via form 3916-bis if outside France, and any subsequent conversion to euros will be taxable. In contrast, a settlement in USD simplifies reporting: no double form, no capital gain on stablecoin.

The practical consequence is interesting. Since profits on financial contracts and capital gains on securities are considered to be of the same nature, a loss on a derivative contract backed by Apple can offset a capital gain realized by selling real shares or tokenized shares. However, it can never reduce a gain on bitcoin, which belongs to a different category. And symmetrically, a crypto loss will never offset a profit on a derivative.

A reserve of honesty

No French administrative doctrine specifically addresses perpetual contracts or long-term futures contracts on stocks. The reasoning presented here is based on the qualification of financial contracts, which is what the platforms themselves retain when operating under European license. This is consistent, but it is not confirmed by a dedicated text. The definitive qualification depends on the exact legal structure of each product, as assessed in light of Articles L 211-1 and following of the Monetary and Financial Code.

The trap that almost no one anticipates

You have held ethers for seven years, with a significant capital gain. You use them to buy tokenized shares or to finance a position on derivatives.

What you receive in exchange is not a crypto asset. The neutrality of exchanges does not apply: the operation can be analyzed as a taxable sale of your ethers, and all the accumulated capital gain becomes taxable immediately, without a cent of euro entering your bank account.

The risk disappears when you buy in euros, which is allowed by platforms with European approval. It is maximal on decentralized protocols, where entry must be made in stablecoins.

Declare: Rules Have Become Significantly Stricter

The form depends on the box. The 2086 for crypto-assets. The appendix 2074 for securities and derivatives, including if you have done everything from a crypto account.

Regardless of any gains, accounts held abroad must be declared: form 3916 for bank and securities accounts, 3916-bis for digital asset wallets.

The law of June 25, 2026, extended this obligation to non-fungible tokens (NFTs) held abroad and strengthened the penalties:

• up to 1,500 euros in fines per undeclared wallet;
• an 80% increase on tax reminders related to omitted assets.

At the same time, the European directive DAC8 has required since January 1, 2026, that platforms automatically transmit their users' data to tax authorities. The gap between what you declare and what the tax office knows is closing quickly.

Three Reflexes to Remember

1. Never assume that a product purchased on a crypto platform is fiscally a crypto-asset. Ask yourself the only question that matters: do I hold a token, a security, or a contract? The qualification depends on the precise legal structure of each product, not its marketing packaging.
2. Avoid paying in cryptocurrencies to enter a product that is not one (security, financial contract), unless you accept the idea of immediate taxation on the latent capital gain on your crypto-assets.
3. Keep your own history (dates, amounts, fees). Very few platforms provide a tax report that is directly usable under French law, especially when mixing crypto-assets, financial securities, and derivatives.

The law in this area is still under construction. For significant amounts, the advice of a tax expert is not a luxury: it is insurance that your investment choices do not turn into costly tax disputes a few years later.
