Frequently asked questions
What are Tax Forms 172 and 173 and do I need to file them?
Form 172 is the informative declaration of virtual currency balances as of December 31. Form 173 covers all operations during the year. Both are mandatory since the 2023 tax year. The platform generates them automatically.
Does it detect DeFi operations, DEX swaps and NFTs?
Yes. It detects swaps on Ethereum DEXes (Uniswap, 1inch…), Jupiter and Raydium swaps on Solana, and ERC-721 NFT transfers. Liquidity operations (LP_ADD / LP_REMOVE) are also recorded.
Does it have special features for accounting firms and tax advisors?
Yes. The Enterprise plan includes a full advisor panel with view-as-client mode, internal annotations, annual executive summary and multi-client management.
Can I connect OKX, Coinbase and KuCoin directly via API?
Yes. In addition to Binance, Pionex, Bybit and Kraken, OKX, Coinbase Advanced Trade and KuCoin are also available with direct API connection, with AES-256-GCM encrypted keys.
Is it legal to use this platform for my tax return?
The platform applies the FIFO method in accordance with applicable tax regulations. We recommend validating the report with a certified tax advisor.
Can I use LIFO, HIFO or WAC in addition to FIFO?
Yes. From your profile you can select between FIFO, LIFO, HIFO and WAC. The chosen method is automatically applied in all reports and in the tax calculator.
How does the tax calculator work?
The what-if calculator simulates the tax impact of a hypothetical sale. Enter the asset, amount and sale price and you get: net gain, estimated tax, effective rate and detail of each consumed lot.
Are my API Keys and wallet addresses safe?
API keys are encrypted with AES-256-GCM. We only configure read-only permissions. You have 2FA, IP whitelist and login alerts from new devices.
Can I pause an exchange or wallet without losing my data?
Yes. Each connection has an activation toggle. When disabled, its transactions are ignored across the platform. Data is not deleted: when reactivated, everything returns instantly.
What happens if I have transfers between my own exchanges?
The platform automatically detects TRANSFER_OUT/IN pairs between exchanges and fiscally neutralizes them. The engine uses a tolerance of 7 days and 5% in amount. If not matched, you can pair them manually.
Do I need to verify my identity (KYC) to use the platform?
No. The platform does not require identity verification. We do not ask for ID, passport or selfies — just your email to create an account. We are a tax calculation tool, not an exchange or custodian.
