“Crypto cost basis reconstruction is the process of rebuilding and reconciling historical digital asset transaction records to establish acquisition costs, tax lots, holding periods, and the information needed to calculate taxable gains and losses. The work may involve recovering exchange histories, tracing wallet transfers, reviewing blockchain transactions, correcting classifications, and documenting historical accounting methods and assumptions.”
“Common causes include missing exchange histories, incorrectly classified wallet transfers, unsupported blockchain transactions, duplicate imports, incomplete acquisition records, and inconsistent tax-lot accounting. Cryptocurrency tax software relies on the underlying transaction information. When that information is inaccurate or incomplete, the resulting cost basis and capital gains calculations may also be incorrect.”
“Yes. Historical reconstruction can identify discrepancies affecting previously filed tax returns, including omitted transactions, inaccurate acquisition costs, incorrect gains and losses, or unsupported reporting positions. Where appropriate, Camuso CPA can evaluate the need for amended returns or other corrective filings. Prior-year tax work is separately scoped based on the applicable facts, records, and filing requirements.”
