Understanding DeFi Taxation in France
Decentralized Finance (DeFi) has revolutionized how investors earn yield through crypto staking, liquidity mining, and lending. But in France, these innovative returns come with tax responsibilities. The French Tax Authority (DGFiP) treats DeFi earnings as taxable income, requiring precise reporting to avoid penalties. As of 2024, failure to comply can trigger audits and fines up to 80% of owed taxes. This guide breaks down France’s complex crypto tax landscape – because even in a decentralized world, tax obligations remain very real.
How France Taxes DeFi Yield: Current Framework
France categorizes DeFi earnings under Revenus de Capitaux Mobiliers (movable capital income) or miscellaneous income, subject to:
- Flat Tax (PFU): 30% rate (12.8% income tax + 17.2% social charges) applies to most yields
- Progressive Income Tax: Up to 45% + 17.2% social charges for non-standard rewards
- Capital Gains Tax: Triggered when selling tokens obtained via DeFi
Tax events occur at yield receipt – not when tokens are sold. Valuation must use EUR market value at acquisition time.
Tax Treatment by DeFi Activity Type
Staking Rewards
Taxed as movable capital income at 30% PFU upon receipt. Example: Earning 1 ETH via staking when ETH = €2,000 creates €2,000 taxable income.
Liquidity Mining & Yield Farming
Reward tokens are taxed as income at market value when claimed. Subsequent token sales incur capital gains tax.
Lending Interest
Platforms like Aave generate interest taxed at 30% PFU. Compounding occurs tax-free until withdrawn.
Airdrops & Hard Forks
Generally taxed as miscellaneous income at progressive rates if received without service exchange.
Step-by-Step Tax Calculation
- Track all DeFi transactions with timestamps and EUR values
- Calculate yield value at receipt date using historical prices
- Apply 30% PFU to standard yields (staking/lending)
- For sold tokens: Capital gain = Sale price – Acquisition value (from step 2)
- Report totals on Form 2086
Note: Long-term holdings (>1 year) qualify for capital gains tax exemption (income tax portion waived).
Reporting on French Tax Returns
File DeFi earnings in two sections:
- Form 2086: Box 2AN for staking/lending yields
- Form 2042-C Schedule: Capital gains from token sales
Required documentation includes exchange statements, wallet addresses, and yield calculation spreadsheets. Deadlines align with standard income tax filing (typically May-June).
Tax Optimization Strategies
- Hold tokens >1 year to eliminate income tax on capital gains
- Offset gains with losses from other crypto investments
- Utilize €305 annual exemption for non-professional activities
- Time withdrawals during market dips to reduce taxable value
Penalties for Non-Compliance
Failure to report DeFi income risks:
- 10% automatic penalty on unpaid taxes
- 40% surcharge for unreported income >€50k
- 80% fraud penalties + criminal charges in severe cases
- Retroactive audits covering 3-6 years
