Crypto tax,
figured out.

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.
