Step-by-step
-
Step 1: Aggregate all transactions
Pull CSV exports from every exchange you used (Coinbase, Kraken, Binance, etc.) and add wallet addresses for on-chain activity. Coverage is everything — even a single missing trade can cascade into wrong cost basis for every subsequent disposal.
-
Step 2: Import into crypto tax software
Koinly, CoinTracker, CoinLedger, Accointing and ZenLedger all support France. Import the CSVs and link the wallet addresses. The software auto-classifies trades, transfers, swaps, staking rewards, and airdrops.
-
Step 3: Reconcile mis-tagged transactions
Most software gets 80% right but flags ambiguous events: cross-platform transfers (which look like sales), bridge events, LP token mints, and rebasing tokens. Review each warning and correct the classification.
-
Step 4: Apply the correct method and jurisdiction
In France, gains are reported as flat 30% (PFU) on disposals; declaration of foreign exchanges via Form 3916-bis. Choose the cost-basis method (FIFO is the default in most jurisdictions) and apply consistently.
-
Step 5: Generate the tax report
Export the France-specific tax report (capital-gains schedule + income-events list). Most software outputs a PDF and the relevant DGFiP format.
-
Step 6: File with DGFiP
Attach the report to Form 2086 and submit through your normal annual filing channel. Keep all underlying CSVs and software outputs for at least 5 years in case of audit.
-
Step 7: Pay any tax owed
Plan for the cash impact — capital gains can hit hard if you traded but never withdrew to fiat. Consider quarterly estimated tax payments if you trade frequently.
Common errors and fixes
- Missing exchange exports for a defunct platform. Use blockchain explorers to reconstruct the missing transactions. If unrecoverable, document the gap and use reasonable basis estimates with disclosure.
- Transfer between own wallets flagged as a sale. Tag both sides as a "transfer" in the tax software. Most platforms auto-detect this when both addresses are linked.
- Staking rewards not picked up. Some chains (Cosmos, Solana) need wallet auto-staking to be enabled in the tool. Manually add validator rewards if missing.
- DeFi LP positions mis-priced. LP token mints and burns are often mis-tagged as trades. Use the tool's "DeFi" view to manually mark them as deposits / withdrawals (not always taxable).
- Wash-sale or bed-and-breakfast rule. France has no crypto-specific wash-sale (bed-and-breakfast) rule; check current local guidance before harvesting losses.
FAQ
Are crypto-to-crypto trades taxable in France?
Generally no — unlike the US or UK, France does not treat crypto-to-crypto trades (BTC→ETH, USDT→SOL, etc.) as taxable disposals for private investors. The taxable event is triggered only when you convert digital assets to fiat currency (euros) or use them to pay for goods or services. Still record every trade, since it affects your overall portfolio cost basis.
Is staking taxable in France?
In most jurisdictions including France, staking rewards are ordinary income at the moment of receipt at fair market value.
Do I need to file if I only held and never sold?
Generally no for buy-and-hold . But if you received airdrops, staking, or any income event, those are taxable even without a disposal.
What if I lost crypto to a hack or rug pull?
France typically allows capital-loss treatment for verifiable theft and hack losses with documentation. File a police report and keep all evidence.
