The short version
A scam loss is not automatically deductible just because the loss was real, painful, or reported to law enforcement. The most important question is usually whether the loss arose from a transaction entered into for profit, which is the IRC 165(c)(2) pathway for many investment-style scam claims.
The IRS now gives financial scam victims a three-part screen: theft under applicable state law, no reasonable prospect of recovery, and a profit-motive transaction. If your facts look more like a personal emergency payment, a romance transfer, or a family-ransom scam than an investment or income-producing property loss, the deduction case is much harder.
What IRC 165 actually allows
IRC 165 starts with a broad rule, losses must be sustained during the tax year and not compensated by insurance or otherwise. For individuals, the statute then narrows the deduction to specific categories, including losses from a trade or business, losses from a transaction entered into for profit, and certain casualty or theft losses.
That structure matters. Most scam-loss planning does not begin with “I was defrauded.” It begins with classification:
| Question | Why it matters | Main source |
|---|---|---|
| Was the conduct theft under state law? | IRS financial scam guidance treats theft classification as a threshold condition. | IRS Pub. 547 |
| Was there a reasonable prospect of recovery? | A loss is not sustained while a realistic reimbursement or recovery claim remains open. | IRS Pub. 547 |
| Was the transaction entered into for profit? | IRC 165(c)(2) is the main route for many investment-scam deductions. | IRC 165 |
| Is the claim reported on the right Form 4684 section and line path? | The filing mechanics differ for income-producing property, Ponzi-type schemes, and other theft claims. | Instructions for Form 4684 |
Publication 547 and the Instructions for Form 4684 both tell financial scam victims to review Chief Counsel Advice 202511015. That memo is not a shortcut for every victim. It is a fact-pattern guide showing why some scam losses fit IRC 165(c)(2) and others remain personal losses.
What the 2025 IRS memo shows
CCA 202511015 walks through five scam situations. The useful lesson is not “crypto scams are deductible” or “romance scams are never deductible.” The useful lesson is that the taxpayer’s motive and the property stolen drive the tax result.
| IRS fact pattern in CCA 202511015 | Core tax point | Deduction result in the memo |
|---|---|---|
| Investment-account transfer scam | Funds were moved for investment purposes before being stolen. | Deductible theft loss under IRC 165(c)(2), assuming no reasonable prospect of recovery. |
| Pig-butchering cryptocurrency investment scam | The taxpayer transferred funds to an apparent investment website and expected profit. | Deductible theft loss under IRC 165(c)(2), assuming no reasonable prospect of recovery. |
| Phishing theft from investment and retirement accounts | The taxpayer did not authorize the theft, so the memo looked to the stolen investment property. | Deductible theft loss under IRC 165(c)(2), with basis limits and account-tax consequences. |
| Romance scam with direct transfers to the scammer | The transfers were personal in nature, not profit-motivated. | Not deductible as an IRC 165(c)(2) loss. |
| Fake kidnapping or emergency-family scam | The motive was to respond to a personal emergency, not to invest. | Not deductible as an IRC 165(c)(2) loss. |
The same memo also warns against assuming the Ponzi safe harbor applies. Even when a scam feels investment-related, the special Ponzi procedure has its own requirements. In the memo, none of the five taxpayers qualified for the safe harbor.
How this works in practice
Assume a taxpayer sent 80,000 dollars to what appeared to be a trading platform. The taxpayer kept screenshots showing an account balance, made a small successful withdrawal, then sent more funds from a brokerage account after being told the platform used a proprietary investment strategy. Later, the platform locked withdrawals, customer support vanished, and the taxpayer filed reports with law enforcement and the financial institution. The institution said the transfer could not be reversed.
That file may have the beginning of an IRC 165(c)(2) argument. It still is not automatic. The tax work is to prove the transaction was entered into for profit, identify the theft theory under state law, measure basis, document recovery efforts, and decide the correct tax year.
Now change one fact. Instead of funding an apparent trading platform, the taxpayer sent 80,000 dollars to someone they met online because that person claimed a medical emergency, travel emergency, or family emergency. The financial harm can be just as serious, but the tax classification changes. Without a profit motive or investment property connection, the deduction case is much weaker.
Timing and recovery prospects
Timing is often where taxpayers make a bad return position worse. IRC 165(e) treats a theft loss as sustained in the year the taxpayer discovers the loss. Publication 547 adds an important recovery rule: if there is a claim for reimbursement with a reasonable prospect of recovery, the loss is not sustained until the taxpayer can determine with reasonable certainty whether reimbursement will be received.
That does not mean you need to wait forever. It means the file should show what recovery channels existed, what you did, what responses you received, and why the remaining recovery path was no longer realistic for the tax year claimed.
What to document before filing or amending
For a scam-loss deduction review, gather the file before deciding whether to claim the loss:
| Document category | What it should show | Why it matters |
|---|---|---|
| Transaction records | Dates, amounts, wallets or accounts, bank wires, exchange records, brokerage activity, retirement-account distributions, and transfers. | Establishes the property, timing, basis, and account-tax consequences. |
| Profit-motive evidence | Investment pitch, platform screenshots, account statements, withdrawal history, emails, messages, contracts, or trading-dashboard records. | Supports the IRC 165(c)(2) theory. |
| Theft evidence | Police report, FBI IC3 report, state attorney general complaint, platform complaint, financial institution report, or other evidence of criminal conduct. | Supports the theft classification condition. |
| Recovery evidence | Bank recall request, exchange support ticket, insurance claim, chargeback record, legal demand, bankruptcy or receivership notice, and written denial or closure records. | Supports the reasonable-prospect-of-recovery analysis. |
| Tax reporting records | Form 1099-R, brokerage tax forms, crypto exchange reports, Form 8949 support, prior returns, amended return draft, and Form 4684 workpapers. | Prevents the loss claim from ignoring taxable distributions, gains, or reporting mechanics. |
Do not treat a police report as a complete tax file. It may help prove theft, but it usually does not prove profit motive, basis, tax year, or the absence of recovery prospects by itself.
Common filing traps
The first trap is claiming a personal scam as an investment loss without evidence that the transaction was entered into for profit. The IRS memo is especially hard on fact patterns where the taxpayer voluntarily sends money for personal reasons, even under deception or pressure.
The second trap is ignoring account-level tax consequences. If stolen funds came from an IRA, brokerage account, or crypto account, the deduction analysis does not erase income, distribution, basis, or gain questions. The CCA repeatedly separates the theft-loss question from the tax consequences of the assets used to fund the transfer.
The third trap is jumping to the Ponzi safe harbor. Section C of Form 4684 is for taxpayers who qualify for the Rev. Proc. 2009-20 procedures and choose to use them. A general online scam, fake platform, phishing theft, romance scam, or emergency-family scam is not automatically a Ponzi-type investment scheme for Section C.

The IRC 165 series should eventually connect this article to the planned ST pillar on IRC 165(c)(2), the planned article on what “entered into for profit” means, and the planned timing article on reasonable prospect of recovery. Those sibling articles were not linked in this draft because they are not yet owner-approved live pages.
If you have already claimed the loss and received an IRS notice, the issue moves from ST planning into an STR response path. That STR article is also not linked here until it is live and owner-approved.
How Sheepdog Tax can help
Sheepdog Tax can review the loss file before you file or amend, test the profit-motive theory against the current IRS guidance, and help organize the evidence into a defensible Form 4684 position. The review focuses on classification, timing, basis, recovery prospects, and the documents the return position would need if questioned later.
Schedule a consultation to evaluate whether your loss may qualify and how to position it properly.
