INATBAHow crypto is taxed
In France, most people who trade crypto are occasional investors, taxed under the prélèvement forfaitaire unique, the flat tax set out in article 150 VH bis. It was 30% for years and rises to 31.4% for 2026 after the social-contribution share increased to 18.6%. The rule that trips up newcomers: trading one crypto for another is not taxable. Selling bitcoin for ether or rotating into a stablecoin triggers nothing on its own. Tax is due only when you convert crypto back to euros or spend it, so you can rebalance all year and calculate a gain only when you cash out. If your total disposals stay at or below 305 euros, the gain is exempt.
France also expects you to declare crypto accounts held abroad on form 3916-bis, filed with your annual return, even if you never sold and the account is empty; the penalty is 750 euros per undeclared account, and more for larger balances. Kryptos follows the French logic directly: it connects to French and global platforms, only realises a gain when you convert to euros, flags which accounts sit with foreign providers for the 3916-bis, and produces the numbers for form 2086 and your 2042-C. Filing runs through the spring, with deadlines from late May into early June depending on your département.

Crypto tax in France: common questions
- Do I have to pay tax on crypto in France?
Yes. DGFiP treats most crypto disposals as taxable events: selling for fiat, swapping one coin for another, spending on goods, or earning yield. Capital-gains rules apply to trading; income rules apply to staking, mining, and airdrops. The exact rate depends on your holding period and bracket.
- Which crypto activities are taxable in France?
DGFiP considers these taxable: disposing crypto for fiat or another crypto, spending crypto on goods or services, receiving staking or mining rewards, getting airdrops, and earning DeFi yield. Transfers between your own wallets aren't taxable. Kryptos auto-classifies each transaction and applies the right treatment.
- What tax forms do I need to file in France?
For France returns, Kryptos generates Form 2042-C (declaration), Form 2086 (disposals), and Form 3916-bis (foreign accounts). We export them as PDF for record-keeping, CSV for accountants, and tax-software-compatible files where supported. Every line traces back to the source transaction so DGFiP questions are answered by your audit trail.
- Does Kryptos support DeFi, NFTs, and staking?
Yes. We support 150+ blockchains and 5,500+ integrations (across DeFi, CEX, wallets, NFTs and on-chain like Uniswap, Aave, Lido, and Curve, plus the major NFT marketplaces). Each is mapped to the right DGFiP treatment: LP-token cost basis, NFT mint and sale events, staking-reward income, governance distributions, perpetual funding rates.
- What happens if DGFiP audits me?
Every transaction Kryptos classifies has an audit trail back to the source: the cost-basis method applied, the exact disposal sequence, and the on-chain or exchange reference for each line. SOC 2 Type II certified means our controls are independently verified. Most clarification requests resolve from the report itself.
