Scam Victim Tax Deduction — What the IRS Actually Allows

When you lose money to a scam, one of the first questions that comes to mind is whether you can get any of it back. While recovering stolen funds directly is often difficult, the IRS does provide certain tax deductions for theft losses. However, the rules are more complicated than most people realize, especially after the Tax Cuts and Jobs Act of 2017 changed the landscape significantly.

This article breaks down exactly what the IRS allows, what Section 165 of the tax code says, and what documentation you need to support a claim.

Section 165: The Foundation of Theft Loss Deductions

Internal Revenue Code Section 165 is the primary provision that governs deductions for losses. Section 165(a) states that any loss sustained during the taxable year that is not compensated for by insurance or otherwise is allowed as a deduction. Section 165(c)(3) specifically addresses theft losses for individual taxpayers.

Under this section, a theft is broadly defined. It includes larceny, embezzlement, robbery, extortion, fraud, and other criminal acts that result in the taking of your property or money. Scams fall squarely within this definition. If someone deceived you into sending money under false pretenses, the IRS considers that a theft for purposes of Section 165.

The loss is calculated as the amount of money or the fair market value of property stolen, minus any insurance reimbursement or other recovery you received. You can only claim the loss in the year you discover the theft, not necessarily the year it occurred.

The TCJA Changes: What Was Suspended

Before the Tax Cuts and Jobs Act took effect in 2018, individual taxpayers could deduct personal theft losses on Schedule A as an itemized deduction, subject to two thresholds. Each loss had to be reduced by one hundred dollars, and the total of all casualty and theft losses had to exceed ten percent of your adjusted gross income.

The TCJA suspended personal casualty and theft loss deductions for tax years 2018 through 2025. This was a significant blow to scam victims who lost money in personal (non-business, non-investment) contexts. However, the suspension included important exceptions.

Exception One: Federally Declared Disasters

Personal casualty losses are still deductible if they are attributable to a federally declared disaster. The President must have declared the event a major disaster under the Stafford Act. While this exception primarily applies to natural disasters like hurricanes and wildfires, it is part of the current framework that taxpayers should understand.

Exception Two: Investment Fraud

This is the exception most relevant to scam victims. If your loss resulted from investment fraud — meaning you invested money based on fraudulent representations — the loss may be treated as an investment loss rather than a personal casualty loss. Investment losses were not suspended by the TCJA.

The IRS issued Revenue Ruling 2009-9 after the Madoff Ponzi scheme collapse, providing specific guidance on how to claim theft losses from fraudulent investment schemes. Under this ruling, victims of qualified investment fraud can claim the loss as an ordinary theft loss deduction on Schedule A, and the usual ten percent AGI threshold does not apply in the same way.

Common scams that may qualify as investment fraud include Ponzi schemes, fake cryptocurrency investment platforms, fraudulent brokerage accounts, and investment advisor fraud. The key factor is whether you gave money with the expectation of earning a return on an investment.

Exception Three: Business Theft Losses

If the theft involved business property or business funds, the loss is deductible as a business loss under Section 165(c)(1). This was not affected by the TCJA. For example, if a vendor defrauded your small business, or if business funds were stolen through a business email compromise scam, the loss can be deducted on your business tax return.

Documentation the IRS Requires

To claim any theft loss deduction, you must be able to substantiate the following:

• That a theft occurred. A police report is the strongest evidence. An FTC report, IC3 complaint, or bank fraud affidavit also supports your claim.
• The amount of the loss. Bank statements, wire transfer confirmations, credit card statements, and cryptocurrency transaction records showing exactly how much you sent.
• When you discovered the theft. This determines the tax year in which you can claim the deduction.
• That no recovery is expected. You must show that you have no reasonable prospect of getting the money back through insurance, legal action, or other means.

IRS Form 4684

Theft losses are reported on IRS Form 4684, Casualties and Thefts. Section A covers personal-use property, and Section B covers business and income-producing property. The form walks you through calculating the deductible amount of your loss, accounting for any insurance or other reimbursement.

Filling out Form 4684 correctly requires understanding the specific rules that apply to your type of loss. Mistakes on this form can trigger an audit or result in a denied deduction. This is one area where professional help pays for itself.
