When someone loses $100,000 to a cryptocurrency scammer, the financial blow is devastating. But finding out whether that loss is tax-deductible means navigating rules written decades before anyone imagined digital theft.
In this episode of Tax in Action, host Jeremy Wells, EA, CPA, tackles a confusing area of tax practice: theft losses. While theft has existed forever, the digital age creates entirely new ways for criminals to steal—from “pig butchering” scams to romance frauds—that challenge how we apply old tax laws to new crimes.
The Three Categories That Determine Everything
Before helping clients who’ve been scammed, tax professionals need to understand which of three categories their loss falls into. This distinction can mean the difference between a valuable deduction and no tax relief at all.
Under IRC Section 165, losses fall into three buckets. Losses from a trade or business and losses from transactions entered into for profit—even outside a business—are generally deductible. However, personal losses not connected to business or profit-seeking are the problem area.
The Tax Cuts and Jobs Act eliminated personal casualty and theft losses for 2018 through 2025. The only exception is losses from federally declared disasters. As Wells explains, this even includes theft during disasters, like the looting that happened after Hurricane Katrina when “there was just a general lack of any sort of law enforcement.”
This means two neighbors could lose the same amount to the same scammer, but only the one who was investing for profit gets a deduction. The retiree who sent money for personal reasons? They’re out of luck.
The Three-Part Test Every Practitioner Must Know
Beyond figuring out the category of the loss, Wells explains that courts have developed three essential criteria for any theft loss claim.
First, the theft must have occurred under state law where the loss happened. This requirement isn’t in the tax code or regulations; it comes from court cases trying to define “theft” when the IRS never did. The 1956 Edwards v. Bromberg case said federal courts must look to state law, but as Wells notes, that creates “probably about 50 different definitions, one for each state.”
Second, you must be able to determine the amount lost. For cash or stocks, this is straightforward. But for jewelry or collectibles? You’ll need insurance records, appraisals, or reasonable estimates. Proving value becomes nearly impossible without documentation from before the theft..
Third, you need to know when the taxpayer discovered the loss. This is crucial because it’s not when the theft happened, but when the victim realized it. Wells emphasizes: “That could be the same day, maybe a few hours later. It could be a few days later. It could be weeks, months, or even years later.”
The courts are clear about one thing: simple disappearance isn’t theft. Wells shares the Allen v. Commissioner case, where someone lost jewelry in a museum. Despite searching everywhere, publishing newspaper ads, and filing police reports, the court denied the deduction. Why? The taxpayer couldn’t prove someone actually stole it rather than it just being lost.
Timing Is Everything (And It’s Complicated)
The timing of theft losses works differently than most people expect, especially with digital assets and cryptocurrency.
A theft loss is deductible in the year you discover it; not when it actually happened. But Wells stresses a major catch: if you have a “reasonable prospect of recovery” through insurance or lawsuits, you can’t claim the loss yet. You must wait until you know with “reasonable certainty” whether you’ll be reimbursed.
“It’s not that you go ahead and claim it, and then wait until you receive the reimbursement,” Wells clarifies. “You have to wait until the outcome of that process is actually either known or within a reasonable certainty.”
With cryptocurrency scams, you might have three different dates spread over years: when the theft occurred, when you discovered it, and when you know recovery is impossible. Each delay pushes your potential deduction further into the future.
When Corporate Fraud Doesn’t Count as Theft
Surprisingly, even massive corporate fraud doesn’t create theft losses for shareholders. Wells uses Enron as an example. Investors lost everything due to “fraudulent and illegal activity,” but for tax purposes, these remain capital losses, not theft losses.
The 1975 Payne v. Commissioner case established this rule. Corporate executives don’t have “specific intent to deprive that particular shareholder” of their money. Even when executives commit crimes that destroy your portfolio, you haven’t been “robbed” in the tax law sense.
This distinction matters enormously for crypto investors. When an exchange halts withdrawals or a platform gets “hacked,” you need to determine whether it’s actual theft (potentially deductible if for profit) or platform failure (capital loss at best).
Five Modern Scams and the Profit Motive Test
In 2025, the IRS Chief Counsel addressed five common scams that don’t fit the traditional Ponzi scheme mold. The key factor? Whether victims had a profit motive.
Deductible scams (entered into for profit) include:
- Pig butchering scams work by “fattening up” victims. Scammers start with small investments that show big returns. Victims invest more and more until the scammer disappears with everything. Because victims expected investment returns, the loss is deductible.
- Compromised account scams involve criminals convincing victims their accounts need securing. Since victims move investment funds expecting to preserve them, the profit motive remains intact.
- Phishing scams use fake websites to steal login credentials for investment accounts. Again, the investment nature preserves deductibility.
Non-deductible scams (personal losses) include:
- Romance scams create fake relationships before asking for funds, often for medical emergencies. There’s no profit expectation; just personal generosity. As Wells emphasizes, “There’s no expectation of profit here. So that makes the theft loss nondeductible.”
- Kidnapping scams involve fake ransom or bail demands. These are fear-motivated, not profit-motivated, making them personal and nondeductible.
The cruel irony? Two victims could withdraw the same amount from identical IRAs and send it to the same overseas account. But only the one expecting investment returns gets a deduction. The one motivated by love or fear gets nothing—plus they owe tax on the IRA withdrawal.
Lessons from the Experts Who Got It Wrong
Wells ends with a humbling case: Booth v. Commissioner. The taxpayer bought Civil War-era land rights that turned out to be invalid, then got sued after selling them to someone else.
Eighteen Tax Court judges split 10-8 on whether this was theft loss or capital loss. The Ninth Circuit reversed them, saying it was both. When Wells polled tax professionals, only 13% got it right.
“There are a lot of smart tax people out there and they can disagree and they can even be wrong,” Wells reflects. “The important part is that we keep thinking about these issues.”
What This Means for Your Practice
For tax professionals dealing with theft losses, three things matter most:
- Document profit motive upfront—not after the loss. The client’s intention when entering the transaction determines deductibility.
- Track timing carefully. Discovery dates and recovery efforts affect when (or if) clients can claim losses. This might mean waiting years.
- Know the current guidance. The IRS issues new interpretations as scams evolve. What wasn’t deductible yesterday might be tomorrow.
The collision between 1950s legal precedents and 2020s digital crimes creates daily challenges. While the basic rules haven’t changed in 70 years, applying them to cryptocurrency scams and online fraud requires both historical knowledge and modern insight.
For clients devastated by digital-age theft, understanding these rules helps you identify opportunities where they exist and provide clarity where they don’t.
