Tax considerations (general pointers)

This is NOT tax advice. Tax law varies wildly by jurisdiction. Consult a qualified accountant or tax attorney before filing.

Rules change. What was true in 2024 may not be true in 2026. Always reference current local guidance.

Most jurisdictions treat crypto perpetual futures as a derivative for tax purposes. Profits and losses are typically realized at the moment of position close, not at mark-to-market unless your jurisdiction requires it.

Some jurisdictions allow loss offsetting against gains within the same tax year. Some require separate treatment of crypto vs other capital gains. Some classify high-frequency trading as business income.

Per-trade: entry timestamp, exit timestamp, entry price, exit price, size, P&L in USD (or your local currency at the trade timestamp).

Per year: total realized P&L, total fees paid, total funding paid/received. Save the CSV export from /app/trades — it has all this.

Wallet addresses involved. Most jurisdictions accept blockchain explorer evidence of transactions; some require it.

For Italian residents, current consensus is that crypto perpetual P&L falls under 'redditi diversi di natura finanziaria' (D.Lgs. 461/97). Tax rate is 26% on net gains. The 2023 budget law clarified some treatments but consult an accountant for specifics.

Italian tax reporting requires the RW form for foreign-held crypto wallets, even if you didn't sell. dYdX is non-Italian. Track wallet balances at year-end.

Reporting only net P&L, not gross gains and losses separately. Some authorities require both.

Forgetting funding payments. They can add up over hundreds of trades.

Not tracking USD-equivalent at the trade timestamp. If you only have crypto-denominated P&L, the tax authority will demand fiat conversion at historical rates.
