Impôts crypto, chaque pays.

Yes. Kryptos has a free tier that connects your wallets and exchanges and generates a tax report for up to 100 transactions, with no card required. Paid plans lift the transaction cap when you outgrow it.

Start with coverage: it should connect the exchanges, wallets, and chains you actually use, and apply your country’s specific rules rather than a generic calculation. Then check that it separates income from capital gains, tracks cost basis correctly, and exports the exact forms your tax office accepts.

You connect your exchanges and wallets by API key or wallet address, and the software pulls in every transaction. It classifies each one, values it in your currency at the time it happened, works out gains and income, and produces a report you can file or hand to your accountant.

It depends on how many transactions you have. Kryptos starts free for small histories and moves to paid tiers as your transaction count grows, so light users pay nothing and active traders pay for the volume they actually run.

No. Form 1099-DA reports what a single broker saw, and brokers must issue it for digital asset sales from tax year 2025. It cannot see the wallet you transferred to, the DeFi position you opened, or what you paid on another venue. If you used more than one platform, the forms will not reconcile to your return on their own, which is the work the software does.

Almost always because a transfer could not be matched, so an asset appears to arrive from nowhere and gets treated as having cost nothing. That inflates the gain, sometimes dramatically. The fix is reconciliation: compare the computed balance against what the exchange or chain actually reports, and resolve the unmatched transfers before generating a report.

Accuracy depends on coverage rather than price. A free tier that connects the same sources and applies the same jurisdiction rules produces the same numbers as a paid one; what free tiers normally limit is transaction volume, or whether you can download the finished report. Kryptos is free up to 100 transactions per tax year and the report is downloadable at that tier.

The question to ask is how much gets classified without you intervening, because the cost of DeFi is manual cleanup rather than the software failing outright. Most tools now classify common liquidity, staking and lending activity automatically and leave a long tail to be tagged by hand. Test your own wallets on a free tier before committing, since the long tail is what differs.

Often not. If every trade happened on one platform that issues a complete tax statement, that statement may be enough. It stops being enough as soon as you move coins to a wallet, use a second venue, or touch DeFi, because no single platform can see the cost basis of assets that arrived from somewhere else.

Software reconstructs the records; an accountant advises on them, and most people with a complicated year want both. High transaction volume, several jurisdictions, a business entity, or several unfiled years are the usual signals that software alone is not enough. The records still need to be clean first, because nobody can advise on a ledger that does not reconcile.

Simply sign up for an account, connect your wallets or exchanges, and start using our tools for crypto tax calculations, portfolio management, and more. You can explore the platform through a free trial before committing to a paid plan.
