Missing Crypto Records? How to Prove Your Cost Basis to the IRS
Missing crypto transaction records can make it difficult to calculate and support your cost basis accurately. When exchange data is incomplete or no longer available, crypto tax software may calculate gains using incomplete information. In this episode, Clinton Donnelly explains ways missing crypto records may be reconstructed using supporting evidence such as trade confirmation emails. He also shares a client case involving Bitcoin transferred from a closed exchange to Coinbase. Although the original exchange transaction history was unavailable, email confirmations were used alongside Coinbase records to support that the incoming Bitcoin represented a transfer of the taxpayer’s own assets rather than taxable income. Clinton also discusses reasonable good-faith estimates, the Cohan rule, and the use of reasonable estimates when complete documentation is unavailable.
