About
Aurum FSG is a crypto-native accounting firm and Koinly reconciliation specialist. It is the team clients turn to when their crypto data has outgrown standard software: DeFi, NFTs, high-volume trading, missing cost basis, and transaction histories that need rebuilding before they can be filed.
Founded in 2020, Aurum FSG works at the intersection of accounting, on-chain analysis, and tax law, serving clients across the United States, United Kingdom, and Germany. The firm has reconciled everything from single-exchange portfolios to accounts with millions of trades across dozens of chains.
Featured crypto tax specialist on Koinly, rated 4.8 on Trustpilot across 600+ clients.
Experience and qualifications
The team is led by a former Big 4 Senior Tax Manager and Bloomberg Tax contributor, alongside Chartered Accountants (CA, ACCA) and specialist crypto reconciliation experts who have worked in digital asset taxation since 2020. Aurum FSG has hands-on experience across centralized exchanges, DeFi protocols, NFT marketplaces, staking, liquidity pools, derivatives, and cross-chain bridges.
Client focus
Aurum FSG specializes in high-complexity cases where automated output needs expert correction: missing cost basis, mislabelled DeFi, zero-cost lots from NFT bidding, duplicate imports, and reconstructing history from exchanges that no longer exist. Every engagement produces a clean, audit-ready report that holds up to scrutiny.
