NODE40 helps tax teams calculate income, gains, and losses on top of transaction history they can trace, explain, and defend when reviewers ask how the result was produced.
Incomplete exchange exports, broken transfer histories, missing wallet context, and smart contract activity that gets flattened into generic transactions all create tax risk. Spreadsheets can produce an answer, but they rarely produce an answer that is easy to defend under review.
NODE40 helps tax teams build reporting on top of verifiable transaction history so gains, losses, and income calculations are not separated from the evidence behind them.
The platform aggregates transactions 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 every transaction where that treatment applies.
That gives tax teams a stronger foundation when the pressure is not just to file, but to support the filing with records that are explainable and review-ready.
Calculate gains, losses, and income on top of records you can defend.
Preserve the links between tax outputs and the underlying transaction record.
Review taxable outcomes with clearer visibility into asset history and movement.
Support return positions with evidence chains that hold up when questions come back.
