Navigating crypto taxation can feel overwhelming, especially with evolving regulations and complex reporting requirements. In France, the 2025 tax landscape for digital assets remains structured yet nuanced—requiring clarity, precision, and proactive compliance. This comprehensive guide breaks down everything you need to know about declaring your crypto holdings: what must be reported, why it matters, and how to do it efficiently and correctly.
Whether you're a casual investor or actively trade across centralized and decentralized platforms, understanding your fiscal obligations is essential to avoid penalties and ensure long-term financial security.
Understanding France’s Unique Crypto Tax Regime
Since 2019, France has implemented a clear legal framework for taxing digital assets under Article 150 VH bis of the General Tax Code. This regime is distinct from traditional financial instruments like stocks or physical goods, applying specifically to non-professional individuals who engage in occasional crypto transactions.
👉 For those trading frequently or earning primary income through crypto activities (e.g., staking, DeFi yield), gains may fall under BNC (Bénéfices Non Commerciaux) starting in 2024—classifying them as professional income.
This specialized approach ensures that all crypto-related gains are accounted for while recognizing different user behaviors and investment strategies.
What Is the Crypto Tax Rate in 2025?
In 2025, capital gains from crypto disposals are generally subject to the Prélèvement Forfaitaire Unique (PFU), commonly known as the flat tax:
- 12.8% income tax
- 17.2% social contributions
- Total: 30%
However, taxpayers have the option to opt into the progressive income tax scale during annual filing if it results in a lower effective rate—especially beneficial for those with modest overall incomes.
💡 Important: If your total annual crypto disposals amount to less than €305, you are exempt from tax—but still required to report these transactions.
Choosing the right taxation method can significantly impact your liability. Strategic planning and accurate recordkeeping are key.

Your Key Tax Obligations in 2025
French law imposes two primary reporting duties on crypto holders:
1. Declare Foreign Crypto Accounts (Form 3916-bis)
If you hold funds on non-French custodial platforms such as Binance, Kraken, or OKX, you must declare these accounts—even if no transactions occurred.
⚠️ This rule applies only to accounts where you don’t control the private keys (i.e., exchange wallets). Self-custody wallets like MetaMask, Ledger, or Phantom are exempt from this requirement.
Failure to comply results in a €750 fine per undeclared account, doubling to €1,500 if the account value exceeds €50,000 at any point during the year.
2. Report Taxable Transactions (Form 2086)
You must report each taxable disposal individually—not just your net gain. These include:
- Selling crypto for fiat (e.g., EUR, USD)
- Using crypto to purchase goods or services
- Spending via crypto debit cards
Each entry requires a calculated capital gain using France’s unique prorated portfolio method.
❓ Are all trades taxable?
No. Swaps between cryptocurrencies (e.g., ETH → USDT) are tax-neutral events under French law—they don’t trigger immediate taxation.
How to Calculate Capital Gains: The French Method
France uses a distinctive formula unlike FIFO or LIFO systems:
Capital Gain = Sale Price – (Total Net Acquisition Cost × Sale Price / Portfolio Value Before Sale)
To apply this correctly, you need:
- Total portfolio value in EUR before each sale
- Cumulative amount invested in fiat
- Exact sale price per transaction
Because this calculation must be repeated for every taxable event, active traders may face hundreds of manual computations annually.

Tax Treatment by Crypto Activity Type
Not all crypto activities follow the standard capital gains rules. Here's how specific use cases are treated:
🏷️ Mining
Rewards from mining are considered professional income (BNC) and must be declared at their fair market value in euros upon receipt. This value becomes the acquisition cost for future disposals.
🏷️ Staking, Lending & Airdrops
- Centralized staking/lending: Treated as BNC income.
- Decentralized staking (e.g., Lido, RocketPool): Best practice is to declare rewards upon receipt.
- Unsolicited airdrops: Typically not taxed at receipt but subject to capital gains upon sale.
🏷️ NFTs
Most NFTs are classified as digital assets, meaning:
- Sales for fiat are taxed like crypto disposals.
- NFT-to-crypto swaps are tax-neutral.
- Regular creators/artists may fall under BNC/BIC regimes.
🏷️ Play-to-Earn Games
- Professional activity: Income taxed under BNC.
- Occasional play: Tokens received are treated as gifts; value integrated into portfolio basis.
🏷️ Crypto Donations
Donating crypto incurs no immediate tax for the giver. However:
- The recipient may owe gift taxes depending on familial ties.
- Their acquisition cost equals the crypto’s value at the time of donation.
When to File Your 2025 Crypto Tax Declaration
The online tax portal opens on April 10, 2025, for reporting 2024 income. Filing deadlines vary by department:
- Departments 01–19: May 22, 2025
- Departments 20–54: May 28, 2025
- Departments 55–976: June 5, 2025
- Paper filers: Must submit by May 22, 2025
Plan ahead—international exchanges often take days to provide transaction histories. Automated tools streamline access to full audit-ready reports instantly.
Risks of Non-Compliance: What Happens If You Don’t Report?
Believing crypto activity goes unnoticed is a dangerous misconception. With EU regulations like MiCA and DAC8 enhancing cross-border data sharing, tax authorities now have unprecedented visibility into digital asset movements.
Consequences of non-compliance include:
- €750 fine per undeclared foreign account (up to €1,500 if over €50K)
- Back taxes plus interest and penalties up to 80%
- Criminal prosecution: up to €3 million in fines and 7 years imprisonment for fraud
While France offers a "right to error" (droit à l’erreur) allowing self-correction before audits (reducing penalties), proving good faith requires detailed documentation—a major advantage of using compliant tracking tools.
Frequently Asked Questions
Q: Do I need to declare crypto if I didn’t sell anything?
A: Yes—if you hold assets on foreign custodial platforms (like Binance), you must file Form 3916-bis regardless of trading activity.
Q: Are crypto-to-crypto trades taxable?
A: No. Under French law, exchanging one cryptocurrency for another (e.g., BTC → ETH) is a tax-neutral event.
Q: How do I prove my acquisition cost?
A: Maintain records of purchase dates, amounts paid in fiat, and wallet transfers. Tools that sync with exchanges automate this process and generate official reports.
Q: Can I get audited for crypto?

Q: Is staking income taxable?
A: Yes—staking rewards are considered taxable income under BNC rules when received.
Q: What if I lost money on crypto?
A: Losses can't offset other income types in France, but they reduce your overall taxable gains when properly documented across multiple disposals.
