Can You Claim a Crypto Scam Tax Deduction? Rules and Reporting

You can claim a crypto scam tax deduction if you lost the money in a transaction you entered into for profit. That covers fake investment platforms, fraudulent staking programs, pig-butchering schemes, and wallet hacks of crypto you held as an investment. It does not cover romance scams, extortion payments, or any other transfer where you had no expectation of financial return. The deductible loss is an ordinary theft loss under Internal Revenue Code Section 165(c)(2), reported on Form 4684 and Schedule A.¹

Everything turns on that profit-motive question. Personal casualty and theft losses are no longer deductible for most taxpayers, so a scam without an investment purpose produces no tax relief even though you were genuinely defrauded.² Investment theft losses were left untouched by that restriction and are not subject to the $3,000 annual cap that limits capital losses.

Which Crypto Scams Qualify

A 2025 IRS legal memorandum sorts crypto scam victims into deductible and non-deductible categories based on two questions: did you authorize the transfer, and if so, why?³

Investment Scams (Deductible)

If you sent crypto or dollars to what you thought was a legitimate investment opportunity, the profit motive is clear. Fake exchanges, fraudulent trading platforms, bogus staking or yield programs, and pig-butchering schemes that lured you with promised returns all qualify. You authorized the transfer, but you did so expecting to make money. The IRS treats this as a deductible theft loss under Section 165(c)(2).³

Wallet Hacks and Unauthorized Access (Usually Deductible)

When a hacker steals your private keys or drains your wallet through a phishing exploit, you never authorized the transfer at all. The question then becomes why you held the crypto. If you held it as an investment, which most individual holders do, the unauthorized taking of investment property is a deductible loss under Section 165(c)(2).³

Romance Scams and Extortion (Not Deductible)

This is where most claims collapse. If you sent crypto to a romantic contact who turned out to be a scammer, paid a ransomware demand, or made any payment that was not itself an investment, there is no profit motive. The IRS classifies these as personal casualty losses under Section 165(c)(3), which are not deductible for most taxpayers.³

Exchange Bankruptcies and Rug Pulls

Frozen funds on a bankrupt exchange are not yet a deductible loss because the transaction is not closed. Once the bankruptcy resolves, treatment depends on what happened. A partial settlement in exchange for your assets is reported as a sale on Form 8949 and Schedule D.⁴ A total worthlessness loss is a miscellaneous itemized deduction, and those are currently suspended. But if the operators criminally stole customer funds, the theft loss rules apply instead and a deduction may be available. Rug pulls follow the same split: fraudulent promises and absconded funds support a theft loss; a project that simply failed does not.

Calculating the Deductible Amount

Your deduction is based on your adjusted basis in the stolen crypto. That means what you actually paid to acquire it, including exchange and network fees. It does not include unrealized appreciation, and it does not include the fictitious profits a scammer showed on your account statements.

If you bought one Bitcoin for $20,000 and it was worth $60,000 when the scammer took it, your deductible loss is $20,000. The $40,000 in gains was never taxed, so it cannot be deducted. Where multiple lots were purchased at different prices, you identify which units were lost; if you cannot, the IRS default is First-In, First-Out.⁵

Subtract from that basis anything you have already recovered or reasonably expect to recover: partial refunds, insurance payouts, clawback distributions, civil judgment proceeds, or protection-fund payments. Only the net loss is deductible.¹

The Ponzi Scheme Safe Harbor

Revenue Procedure 2009-20 gives victims of “specified fraudulent arrangements” a simpler calculation. These are schemes where a lead figure collects investor money, reports fake income, and pays earlier investors with later investors’ funds. Many crypto investment scams fit this pattern.⁶

Under the safe harbor, your deductible loss is:

95% of your qualified investment if you are not pursuing third-party recovery
75% of your qualified investment if you are pursuing or plan to pursue third-party recovery

Qualified investment means total amount invested, minus withdrawals, minus actual or expected recoveries. Using the safe harbor requires attaching a statement to your return agreeing to its terms, including reporting any future recovery as income. Safe-harbor claims go on Form 4684, Section C.⁷

Which Tax Year You Claim It

A theft loss is deducted in the year you discover it, not the year the theft happened.¹ If a scammer drained funds throughout 2025 but you did not realize it until January 2026, the loss belongs on your 2026 return. Document the discovery date with a police report, a regulatory complaint, or the date the missing funds first came to your attention.

One exception: if you have a reasonable prospect of recovering some or all of the money at the end of the discovery year, you cannot deduct the potentially recoverable portion yet. It waits until the year you can determine with reasonable certainty whether recovery will happen.⁸ A concrete claim against an identifiable, solvent defendant creates a reasonable prospect. An anonymous scammer operating from an unknown location generally does not.⁹ Vague hope that law enforcement might someday find something is not enough to defer the deduction.

Missed the deduction in an earlier year? You can amend. The deadline is the later of three years from the original filing date or two years from the date you paid the tax for that year.¹⁰

Documentation You Need

The burden of proof sits entirely on you. Build the file around three things.

Cost basis. Bank or card statements showing the fiat you sent to buy the crypto, exchange transaction histories showing purchase prices and fees, and blockchain transaction IDs linking your purchases to the assets that were eventually lost. Keep any exchange-issued tax forms such as Form 1099-B.⁵

The loss event. Blockchain records of the transfer to the scammer’s address, screenshots of the fraudulent platform, and any communications with the scammer. If the scam site has since disappeared, archived captures matter more.

Criminal conduct. File a police report even if local police cannot act on it, because the report itself is evidence. Complaints with the FBI’s Internet Crime Complaint Center (IC3), the SEC, or the FTC add weight. Indictments, civil complaints, or regulatory enforcement actions naming the scheme independently confirm that a crime occurred rather than a bad investment.

Reporting the Loss on Your Return

Investment theft losses go on Form 4684, Section B, which covers income-producing property. Not Section A, which is for personal-use property.⁷

In Section B, Part I, Line 19 takes a description of the property. Be specific: “2.5 Bitcoin stolen from fraudulent investment platform [name].” Line 20 is your adjusted basis. Line 21 is any insurance or reimbursement.¹¹ The remaining lines produce the final loss, which flows to Section B, Part II. Ponzi safe-harbor claims are calculated in Section C and the result is entered on Part II of Section B.

The final amount from Form 4684 goes to Schedule A, Line 16, under “Other Itemized Deductions.”¹² The Schedule A instructions specifically list casualty and theft losses of income-producing property, including losses from financial scams, as belonging on that line. Because this is an ordinary loss rather than a capital loss, it is not capped at $3,000 and does not have to be paired against capital gains.¹³

The tradeoff: because the deduction sits on Schedule A, you have to itemize. For most victims with a significant scam loss, the loss alone will exceed the standard deduction, so itemizing makes sense.

When the Loss Is Bigger Than Your Income

A large scam loss can eliminate your entire taxable income for the year and create a net operating loss. The excess carries forward to future years indefinitely, but a carryforward from a post-2017 year can only offset up to 80% of taxable income in any given future year.¹⁴ The remaining 20% of your income stays taxable in each carryforward year regardless of how much unused loss you still have. Use Form 172 to calculate and track it.

If You Recover Funds Later

Money that comes back later, from a seizure, class action settlement, or bankruptcy distribution, is generally taxable income in the year received, but only to the extent your original deduction actually reduced your tax. This is the tax benefit rule. If the deduction produced no tax savings that year (because your income was already zero, for instance), the recovery is not taxable.¹⁵ Ponzi safe-harbor users agreed as a condition of using it to report future recoveries as income, so track every inflow connected to the fraud and report it in the year you receive it.
