Portfolio Reconciliation

Portfolio reconciliation is the process of comparing an investor's internal records of assets and transactions against the records provided by exchanges, wallets, or custodial services. This ensures that the data used for tax reporting and performance analysis is accurate and complete.

In the complex world of decentralized finance, where assets may move across multiple chains and protocols, discrepancies are common. Reconciliation involves identifying and resolving these differences, which could be caused by missed transactions, incorrect fee recording, or protocol errors.

It is a vital step in maintaining the integrity of financial data and ensuring that tax filings are based on a true and accurate representation of the portfolio. Effective reconciliation is the cornerstone of reliable tax compliance and performance measurement.
