A Painful Question With a Technical Answer
Falling victim to a scam or a cryptocurrency fraud is financially and emotionally devastating. Victims understandably ask whether the tax code offers any relief—whether the loss can at least be deducted. The answer is a lawyer's answer: it depends, and it depends on distinctions that are far from intuitive. The treatment turns on the nature of the loss, the victim's intent in parting with the funds, and the significant limitations imposed by the Tax Cuts and Jobs Act.
As counsel advising individuals through the aftermath of fraud, I approach these losses methodically, because sloppy characterization can either forfeit a legitimate deduction or claim one that will not survive examination.
The Starting Point: Section 165 Theft Losses
The deduction for theft losses arises under Section 165, which allows a deduction for losses sustained during the year that are not compensated by insurance or otherwise. A theft, for tax purposes, generally requires that the taking be illegal under the law of the relevant jurisdiction and be done with criminal intent. Fraudulent schemes—where a perpetrator induces a victim to transfer funds through misrepresentation—can qualify as theft, because the victim's consent was procured by deception.
Establishing a theft loss requires showing that a theft occurred, the amount of the loss, the year in which the loss was discovered, and that there is no reasonable prospect of recovery. That last element is important: if there is a pending claim or reasonable prospect of recovering some or all of the funds, the deductible loss may be deferred or reduced until the recovery prospects are resolved.
The TCJA Limitation That Changed Everything
Here is the critical complication. The Tax Cuts and Jobs Act suspended, for most individuals, the deduction for personal casualty and theft losses except those attributable to federally declared disasters. This means that a purely personal theft loss—money stolen with no profit-seeking dimension—generally cannot be deducted during the suspension period unless it fits the disaster exception.
For scam and crypto-fraud victims, this suspension is often the decisive obstacle. If the loss is characterized as a personal theft loss, the TCJA limitation typically forecloses the deduction. The entire analysis, therefore, frequently comes down to whether the loss can properly be characterized as something other than a personal theft loss.
The Profit-Motive Distinction
The most important exception for many fraud victims is the treatment of losses arising from transactions entered into for profit. Losses incurred in a transaction entered into for profit—even if not connected to a trade or business—are treated differently from purely personal losses and are not subject to the same personal-casualty suspension.
This distinction is decisive in the crypto and investment-fraud context. Consider a victim who was induced, through a fraudulent scheme, to transfer funds believing they were making an investment expected to generate a return—a fake trading platform, a bogus crypto yield program, or a sham investment fund. Because the victim parted with the funds with a profit motive, the resulting loss may be analyzable as a loss from a transaction entered into for profit rather than a personal theft loss, potentially preserving a deduction that the TCJA would otherwise bar.
By contrast, a scam that simply tricks a victim into sending money with no investment or profit-seeking character—an impersonation scam, for instance—looks far more like a personal theft loss subject to the suspension.
The facts of how and why the victim transferred the funds are therefore not incidental; they are the heart of the tax analysis.
Documentation and Proof
Regardless of characterization, the victim must be able to prove the loss: the amount transferred, the fraudulent nature of the scheme, the profit-seeking purpose where relevant, the year of discovery, and the absence of a reasonable prospect of recovery. Contemporaneous records—communications with the perpetrator, transaction records, platform representations, and any law-enforcement or reporting documentation—form the evidentiary backbone. In the crypto context, blockchain transaction records can be valuable proof of both the transfers and their destination.
Timing and Recovery
Because the deduction generally requires that there be no reasonable prospect of recovery, timing can be subtle. If a receiver, class action, or law-enforcement forfeiture proceeding offers a realistic chance of partial recovery, the deductible amount and the proper year may shift. Victims should not assume the deduction is available in the year of the loss without analyzing the recovery landscape.
The Practical Takeaway
Whether a scam or crypto-fraud loss is deductible is not a yes-or-no question but a characterization question. The profit-motive framing is often the difference between a preserved deduction and one barred by the TCJA. Because the stakes are high and the analysis fact-intensive, victims should have the specific circumstances of their loss evaluated rather than relying on general assumptions—favorable or unfavorable—about deductibility.
