How to Report Bitcoin Gains in France: Your Complete 2024 Tax Guide

As cryptocurrency adoption grows in France, understanding how to report Bitcoin gains has become crucial for investors. The French tax authority (Direction Générale des Finances Publiques – DGFiP) treats cryptocurrencies like Bitcoin as movable property, meaning profits from their sale are subject to capital gains tax. Failure to properly declare these gains can result in penalties up to 80% of the tax due. This comprehensive guide breaks down the process step-by-step to ensure you remain compliant with French tax laws.

Understanding Taxable Bitcoin Events in France

Not all Bitcoin transactions trigger tax obligations. You must report gains when these events occur:

• Selling Bitcoin for fiat currency (e.g., converting BTC to EUR)
• Trading between cryptocurrencies (e.g., exchanging BTC for ETH)
• Using Bitcoin to purchase goods/services exceeding €5,000 annually
• Receiving Bitcoin as payment for freelance work or services

Note: Simply holding Bitcoin or transferring between your own wallets isn’t taxable. Tax applies only upon disposal.

How to Calculate Your Bitcoin Capital Gains

French crypto tax calculation follows this formula:

Capital Gain = Selling Price – (Acquisition Cost + Associated Fees)

1. Determine acquisition cost: Use FIFO (First-In-First-Out) method to identify purchase price of disposed coins
2. Include transaction fees: Add platform fees, miner fees, and exchange commissions to cost basis
3. Convert values to euros: Use exchange rates at transaction time (keep records!)
4. Apply flat tax rate: Gains are taxed at 30% (12.8% income tax + 17.2% social charges)

Example: If you bought 0.5 BTC for €10,000 (including €50 fee) and later sold it for €15,000 (€100 fee), your gain is €15,000 – €100 – (€10,000) = €4,900. Tax due: €4,900 × 30% = €1,470.

Step-by-Step Reporting Process for Bitcoin Gains

1. Track all transactions: Maintain records including dates, amounts, EUR values, and wallet addresses
2. Calculate annual net gain: Offset gains with losses from other crypto disposals
3. Complete Form 2086: Attach this supplementary form to your annual income tax return
4. Declare in your main tax return: Report total net gains in Box 3VG of Form 2042
5. Submit by deadline: Typically late May/early June for paper returns, early June for online filings

Essential documents: Transaction histories from exchanges, wallet statements, and conversion rate proofs (e.g., Banque de France rates).

Common Bitcoin Tax Reporting Mistakes to Avoid

• Ignoring crypto-to-crypto trades: Every exchange between cryptocurrencies is a taxable event
• Forgetting fee deductions: Transaction costs reduce taxable gains
• Miscalculating holding periods: While France has no reduced long-term rate, accurate dates are still vital
• Underreporting small transactions: All disposals must be reported regardless of amount
• Missing the declaration threshold: You must report if total disposal value exceeds €305 per year

Bitcoin Tax FAQ: France-Specific Questions Answered

Do I pay tax if I transfer Bitcoin between my wallets?

No. Transfers between wallets you control aren’t disposals and aren’t taxable.

What if I mine Bitcoin?

Mining rewards are taxed as non-commercial profits (BNC) at income tax rates + 17.2% social charges. Declare on Form 2042 C PRO.

Are there any tax exemptions?

Occasional sellers with total disposal values under €305/year are exempt. Professional traders may qualify for micro-BNC regime under €72,600/year.

How does the DGFiP track crypto transactions?

What penalties apply for non-compliance?

Up to 40% penalty for late declaration, 80% for intentional fraud, plus 0.2% monthly interest on unpaid tax.

Pro Tip: Use crypto tax software like Koinly or Accointing that supports French tax rules to automate calculations. Always consult a French tax advisor for complex situations. Proper reporting not only avoids penalties but establishes financial credibility as crypto regulations evolve.
