Losing cryptocurrency to an investment scam can leave victims with more than missing funds: they also need evidence of what happened. AnChain.AI helps victims trace stolen crypto and prepare blockchain forensic reports that their tax professionals can use to evaluate and substantiate potential tax deductions.
Certain investment scams may qualify for a theft-loss deduction under the IRS Section 165(c)(2). The IRS identifies three key conditions: criminal theft under applicable state law, a transaction entered into for profit, and no reasonable prospect of recovering the claimed amount. Timing matters: the deduction generally belongs to the discovery year, subject to recovery prospects at year-end.

A qualifying investment theft is not subject to the $3,000 annual net capital-loss limit against ordinary income. Ordinary capital losses first offset capital gains; unused net losses generally carry forward after the annual allowance. Personal scam losses remain generally restricted, and an unsold token’s price decline alone does not establish a deductible loss.

A forensic report connects the victim’s records to verifiable blockchain activity. Depending on the engagement and available evidence, AnChain.AI can help:
The objective is a clear, reviewable account of the loss and the evidence supporting it.

The same stolen assets may move through many wallets. Those transfers help explain the fund flow but must not be counted as separate losses. Investigators distinguish verified transactions from attribution estimates and document gaps in the available records.

AnChain.AI combines AI-assisted tracing and reporting with investigator review to organize transaction evidence into a readable forensic narrative. Wallet flows, source records, and recovery leads give the tax professional a stronger factual basis for assessing the claim.
A report should disclose both recovery obstacles and viable leads. Funds reaching an exchange may create an investigative opportunity; an empty wallet does not, by itself, prove that recovery is unlikely.

In a simplified example, assume a tax professional establishes a $90,000 qualifying deduction after accounting for basis and recoveries. If the entire additional deduction offsets income otherwise taxed at 24%, the illustrative federal tax reduction is $21,600. Actual savings depend on the return; a deduction is not reimbursement of the stolen funds. Fictitious platform profits do not automatically increase the deductible amount.
