Build an accurate history for each tax year first. A tax adviser can then advise on the right route for past years.

Get your full history and figures together before you reply, so you can answer accurately.
Hand over one report with the schedules behind every number, so they can check it instead of rebuilding it.
Connect your exchanges and wallets and Coinfig pulls in your full history for you, with nothing to type in by hand. Your transactions are kept in sync. For wallets we read the blockchain directly, which picks up movements that exported statements often leave out.
For the technically minded: we run our own archive nodes for Bitcoin, Ethereum, Bitcoin Cash, Litecoin, Dogecoin and Cardano.
Direct, read-only API connections to the venues you actually use, local and global, plus a universal CSV importer for everything else.
Add a wallet address and we read its history from the blockchain itself, transaction by transaction. There is no file to export.
Coinfig checks whether anything is missing from your history and shows you what to fix. You get a data completeness score from 0 to 100, so you know how far to trust your figures before you pay.
We compare everything that came into your accounts with everything that went out, coin by coin. Small gaps count for little, so a €1 gap does not spoil a clean year.
When crypto arrives from a wallet or exchange you have not connected, we value it at the market price on the day, which is an estimate. Connect that account and we use the real figure. Your score is the lowest of the checks.
Link your exchanges, add your wallet addresses, or upload a file from an exchange we do not connect to yet.

Everything you need to know about Coinfig and your crypto tax reporting.
Coinfig turns your exchange and wallet history into clear gain figures for the French calendar tax year. It uses the portfolio-proportional method set out in article 150 VH bis of the tax code, working out your proceeds and a proportional share of your total acquisition cost on every taxable disposal.
You get downloadable, transaction-level schedules and workings that support your return. Coinfig is a calculation and reporting tool, not tax advice, and it does not imply any endorsement by the DGFiP.
France does not tax crypto lot by lot. Instead it looks at your whole portfolio. When you cash out, the taxable gain is based on the proceeds less a proportional share of the total acquisition price of everything you hold.
Coinfig tracks your total acquisition cost across all your wallets and exchanges and recovers the proportional basis on each cash-out, with the working shown behind every figure.
Generally no. A pure crypto-to-crypto exchange, with no cash balancing payment, is treated as being in sursis and is not taxed at the moment of the swap. Tax arises when you cash out to euros or spend crypto on goods or services.
Coinfig defers these swaps in line with that treatment and counts them when a taxable cash-out actually happens.
Gains for private investors are generally taxed under the flat tax, the prélèvement forfaitaire unique, which is usually 30 percent overall. Your actual rate and any options depend on your circumstances.
Coinfig computes the taxable gain, not your final liability, and shows the workings so you or your adviser can complete the return.
Income from activities such as mining, and some staking or more professional activity, can be taxable under different rules from private investment gains, depending on how regular and organised the activity is.
Coinfig records these separately from your investment disposals. Because the treatment depends on the facts, confirm your situation with a tax adviser.
Yes. When you connect an exchange through its API, Coinfig uses read-only access to import your transaction history. It cannot place trades or move funds.
If you prefer not to share an API key, you can also import your history by CSV from most exchanges.
No. Coinfig provides calculations and reports based on the data you import and the settings you choose. It does not provide personalised tax advice, and it does not imply any endorsement or approval by the DGFiP.
For complex situations, such as business or professional trading, mining or unusual transactions, consult a qualified tax adviser. You remain responsible for what you file.
