Crypto Loss Documentation & Reconstruction

Why You Need Formal Documentation for Cryptocurrency Losses

Lost crypto to a scam, hack, or exchange bankruptcy? Our experts provide IRS-compliant crypto loss documentation to help you claim tax deductions and survive audits. We reconstruct wallet activity, quantify losses, and prepare organized documentation your CPA, attorney, or internal team can use to evaluate next steps.

Why You Need Formal Documentation for Cryptocurrency Losses

When crypto fraud, platform failures, wallet access issues, or major unrecoverable losses occur, the hardest part is often turning scattered blockchain activity into something usable. We help clients rebuild wallet activity, organize transaction history, and prepare clear documentation packages that can be used by their CPA, attorney, or internal advisors.

We do not provide legal opinions or formal tax opinions as part of this service.
Our role is to reconstruct activity, organize records, quantify losses, and prepare a clean documentation package that your CPA or attorney can use to evaluate treatment and next steps.

Can You Deduct Crypto Scam Losses on Your Taxes?

In some cases, crypto scam or fraud-related losses may qualify for special tax treatment depending on the underlying facts, documentation, and how the loss occurred. The difficulty for most taxpayers is not just the tax question — it is proving what happened through complete transaction history, wallet records, and supporting evidence. Our role is to help reconstruct and organize that information so your CPA or attorney has a clear foundation to review.
