Crypto Tax Reporting Built for Returns You Can Support

Soft promises to “simplify tax reporting” fall apart when the numbers cannot be tied back to the underlying transaction history. Incomplete exchange exports, broken transfer chains, missing wallet context, and flattened smart contract activity can all produce outputs that are difficult to support during return preparation or when a reviewer asks how cost basis was established.

NODE40 helps tax teams build reporting on top of verifiable transaction records, so gains, losses, and income calculations remain linked to the activity, valuations, and movements that produced the result.

The platform aggregates activity from multiple sources, classifies what actually happened, applies market valuations, and carries cost basis through transfers, dispositions, staking, NFTs, and DeFi activity. It uses tax lot identification (SpecID) to help assign a defensible basis to each transaction where that treatment applies.

That gives tax teams more than a finished calculation. It gives them a clearer evidentiary path from underlying activity to reported outcome, which matters when documentation gaps, reviewer questions, or return-support requests surface later.
