If your cryptocurrency has been stolen, hacked, or lost to a scam, you may be wondering whether you can claim a tax deduction. The answer depends on a complex set of rules involving the Tax Cuts and Jobs Act (TCJA), the nature of your transaction, and the specific facts of your case. This guide explains the legal framework, reporting requirements, and practical steps you need to know for the 2025 and 2026 tax years.
The foundation for claiming a theft loss deduction is Internal Revenue Code Section 165. This section allows taxpayers to deduct losses sustained during the taxable year that are not compensated by insurance or otherwise[reference:0][reference:1].
For individual taxpayers, IRC § 165(c) limits deductions to three specific categories[reference:2]:
Under IRC § 165(e), a theft loss is treated as sustained during the taxable year in which the taxpayer discovers the theft, not the year the money was actually taken[reference:3][reference:4]. This is a critical distinction: if you discover a theft in 2025, you claim the deduction on your 2025 tax return, even if the theft occurred in 2024[reference:5][reference:6].
The deduction is limited to your tax basis in the stolen cryptocurrency—the amount you originally paid for it, including fees—not the fair market value at the time of theft[reference:7][reference:8].
The Tax Cuts and Jobs Act (TCJA) of 2017 significantly restricted theft loss deductions for individual taxpayers[reference:9].
For tax years 2018 through 2025, personal casualty and theft losses under § 165(c)(3) are deductible only if they arise from a federally declared disaster[reference:10][reference:11]. This means that if your crypto was stolen as a personal asset (e.g., from a personal wallet for non-investment purposes), you generally cannot claim a theft loss deduction for 2025[reference:12][reference:13].
However, the TCJA suspension does not apply to theft losses under § 165(c)(2)—losses incurred in a transaction entered into for profit[reference:14]. This is the key exception that allows many crypto investors to claim deductions for thefts and scams[reference:15].
The difference between a deductible and non-deductible crypto theft loss comes down to one question: Were you holding the crypto for investment or profit-making purposes? If yes, you may qualify under § 165(c)(2). If the crypto was held for personal reasons, the loss is generally not deductible through 2025[reference:16].
The profit-motive exception under § 165(c)(2) is the primary pathway for crypto investors to claim theft loss deductions. To qualify, you must demonstrate that the stolen cryptocurrency was held in connection with a transaction entered into for profit[reference:17].
According to recent IRS guidance, a profit motive can be established in several scenarios[reference:18][reference:19]:
The IRS has clarified that losses from personal scams—such as romance scams, false kidnapping schemes, or personal transfers made for non-investment reasons—do not qualify for the deduction under current law due to the TCJA restrictions on personal casualty and theft losses[reference:23].
Even if you have a profit motive, you must also demonstrate that there is no reasonable prospect of recovering the stolen funds[reference:24][reference:25]. If there is a pending lawsuit, ongoing investigation, or possibility of recovery, you may need to wait until the recovery prospects are resolved before claiming the deduction.
If you lost cryptocurrency through an investment scam and have no reasonable prospect of recovery, you may be eligible to claim a theft loss deduction under § 165(c)(2) on your 2025 tax return—even though personal theft losses are generally suspended[reference:26].
On March 14, 2025, the IRS Office of Chief Counsel released Chief Counsel Memorandum 202511015, providing important clarification on when scam victims may claim a theft loss deduction[reference:27][reference:28].
The memo affirms that taxpayers who are victims of scams may claim a theft loss deduction under IRC § 165, but only if specific conditions are met[reference:29][reference:30]:
The memo analyzes five scam scenarios[reference:31][reference:32]:
The IRS concluded that Taxpayers 1, 2, and 3 sustained a theft loss under IRC § 165 because they incurred the loss in a transaction entered into for profit, discovered the loss in 2024, and had no reasonable prospect of recovery[reference:33].
While the Chief Counsel memo is an important signal, it is not formal law or binding precedent[reference:34]. It reflects the IRS's interpretation and provides guidance for taxpayers, but each case depends on its specific facts.
To claim a theft loss deduction, you must provide clear and convincing evidence of the theft, the amount of the loss, and your lack of recovery prospects[reference:35]. The burden of proof rests entirely on you as the taxpayer[reference:36].
Keep all records for at least three years from the date you file your return. If you carry forward losses to future years, consider keeping records for seven years or longer.
Detailed worksheets showing how you computed your crypto cost basis, how you valued the loss in US dollars, and how you accounted for reimbursements or expected recoveries will strengthen your position in case of an audit[reference:40].
You report a theft loss on Form 4684, Casualties and Thefts[reference:41][reference:42]. For investment-related theft losses under § 165(c)(2), you use Section B of Form 4684[reference:43]. The loss is reported as an ordinary loss, not a capital loss, which means it is not subject to the $3,000 capital loss limitation[reference:44].
For a § 165(c)(2) theft loss (investment-related), the loss from Form 4684, Section B flows to Schedule 1 (Form 1040), line 8z (Other Income), where it is reported as a negative amount, reducing your adjusted gross income.
For losses discovered in 2025, you must document the theft and file your claim on your 2025 tax return (filed in 2026)[reference:45]. The deduction is claimed in the year of discovery, not the year the theft occurred[reference:46].
Every Form 1040 filer must answer the digital asset question. If you are claiming a theft loss, you should answer "yes" and be prepared to provide supporting documentation[reference:47].
If you received a settlement or insurance payment for the stolen crypto, you must reduce your deduction by the amount you received[reference:48].
Understanding the difference between a theft loss and a capital loss is critical for proper tax treatment.
| Characteristic | Theft Loss (§ 165(c)(2)) | Capital Loss (Sale/Exchange) | Personal Theft Loss (§ 165(c)(3)) |
|---|---|---|---|
| What triggers it? | Criminal theft of investment assets | Selling or exchanging crypto for less than basis | Personal property theft (non-investment) |
| Form used | Form 4684, Section B | Form 8949 + Schedule D | Form 4684, Section A + Schedule A |
| Loss type | Ordinary loss | Capital loss | Itemized deduction (personal) |
| TCJA suspension (2018–2025) | Not suspended | Not affected | Suspended (except federally declared disasters) |
| Deduction limit | No limit (reduces AGI) | $3,000 per year against ordinary income | 10% AGI floor + $100 reduction (pre-2018 rules) |
| Carryforward | No carryforward needed (ordinary loss) | Yes, indefinitely | No (personal losses not carried forward) |
| Proof required | Theft, criminal intent, no recovery | Sale or exchange transaction records | Theft, no recovery |
Current as of mid-2026. Tax laws are subject to change.
Not every scam or theft qualifies for a deduction. The loss must be connected to a profit-motive transaction. Personal scams do not qualify under current law[reference:49].
A theft loss requires a "closed and completed transaction"[reference:50]. You cannot claim a loss simply because the value of your crypto dropped; you need an identifiable theft event[reference:51].
The deduction is limited to your tax basis in the stolen crypto, not its fair market value at the time of theft[reference:52]. This is a common and costly error.
Without a police report, exchange statements, and transaction records, the IRS may disallow your deduction[reference:53]. Documentation is essential.
If there is any possibility of recovery, you may need to wait until that possibility is resolved before claiming the deduction[reference:54].
A theft loss requires criminal conduct. If your token simply failed or became worthless without fraud, it may be treated as a capital loss from a worthless investment, not a theft loss[reference:55].
Use this checklist to prepare for claiming a cryptocurrency theft loss deduction:
Facts: Alex responded to an unsolicited email advertising a cryptocurrency investment opportunity in June 2024. Alex created an account on the platform, made small initial deposits that appeared to generate profits, and was able to withdraw modest amounts. In November 2024, Alex invested $25,000 (transferred from a brokerage account). When Alex attempted to withdraw the funds in December 2024, the account was frozen, customer support disappeared, and the platform went offline. Alex discovered the theft in December 2024 and filed a police report in January 2025.
Analysis:
Result: Alex can claim a theft loss deduction under § 165(c)(2) on the 2024 tax return (filed in 2025) because the loss was discovered in 2024[reference:60]. The deduction is limited to Alex's cost basis of $25,000, not the fair market value of the crypto at the time of theft[reference:61].
Key Lesson: The timing of discovery is critical. If Alex had discovered the theft in January 2025, the deduction would be claimed on the 2025 tax return instead.
This scenario is for illustrative purposes only and does not constitute tax advice. Actual tax treatment depends on specific facts and circumstances.
The tax landscape for theft loss deductions is highly uncertain as we approach 2026. The current rules are shaped by a combination of statutory provisions, pending legislation, and administrative guidance.
The TCJA restrictions on personal casualty and theft losses are scheduled to expire on December 31, 2025[reference:62][reference:63]. Unless Congress extends or modifies these provisions, theft loss deductions may become available again for the 2026 tax year under the pre-2018 rules[reference:64].
If the TCJA provision sunsets, personal theft losses would once again be deductible as itemized deductions on Schedule A, subject to the pre-2018 limitations[reference:65][reference:66]:
However, several proposals in Congress would extend or make permanent various TCJA provisions, including the theft loss suspension[reference:67][reference:68]. The outcome remains uncertain.
The IRS continues to develop guidance on digital asset taxation. Form 1099-DA reporting requirements, the classification of digital assets, and the treatment of various crypto transactions are all evolving areas[reference:69].
The information in this guide reflects the law and IRS guidance as of mid-2026. Tax laws are subject to change, and the status of the TCJA suspension may be modified by Congress at any time. Always verify current rules with a qualified tax professional before filing.

It depends. Under the Tax Cuts and Jobs Act (TCJA), personal theft losses are generally not deductible for 2018–2025 unless they result from a federally declared disaster. However, if the theft occurred in connection with an investment or profit-motivated transaction, it may qualify as a deduction under IRC § 165(c)(2), which is not subject to the TCJA suspension.
The TCJA restrictions on personal casualty and theft losses are scheduled to expire at the end of 2025. If Congress allows the provision to sunset, theft loss deductions may become available again for the 2026 tax year under the pre-2018 rules, subject to the 10% AGI floor and $100 per-event reduction. However, legislative changes could extend or modify these rules.
Section 165(c)(2) covers losses incurred in a transaction entered into for profit, such as investment scams. This deduction is not subject to the TCJA suspension and is not limited by the capital loss rules. Section 165(c)(3) covers personal casualty and theft losses, which are generally suspended for 2018–2025 under the TCJA.
You need: a police report filed promptly after discovering the theft, exchange statements showing your purchase and ownership records, transaction histories, correspondence with the scammer or platform, and documentation of any recovery efforts. You must also document the date you discovered the theft and prove there is no reasonable prospect of recovery.
You report a theft loss on Form 4684, Casualties and Thefts. For investment-related theft losses (under § 165(c)(2)), you use Section B of Form 4684. The loss is limited to your tax basis in the stolen cryptocurrency, not the fair market value at the time of theft.
Possibly. If the exchange collapse involved fraud or theft under state law, and you held the assets for investment purposes, you may qualify for a theft loss deduction under § 165(c)(2). However, losses from bankruptcy proceedings may not be deductible until the proceedings are closed and you have a finalized loss amount.
Issued in March 2025, this memo clarifies that scam victims may claim a theft loss deduction under IRC § 165 if the loss involves criminal conduct, there is no reasonable prospect of recovery, and the loss arose from a transaction entered into for profit. The memo provides examples including compromised account scams, pig butchering investment scams, and phishing scams.
Yes. Cryptocurrency theft loss deductions are complex and fact-specific. The rules involving profit motive, the TCJA suspension, and documentation requirements are nuanced. A qualified tax professional can help you determine your eligibility and ensure proper reporting.
