How Much Can I Deduct for a Scam Loss on My Federal Return?

One of the first questions scam victims ask is: “How much can I actually deduct?” The answer depends on several factors, but for many victims the deduction is substantial — and it can produce a real reduction in federal income taxes owed, or even a refund of taxes already paid. Here is how the calculation works under IRC Section 165(c)(2).

The Basic Formula: Net Investment Loss

Your deductible loss under Section 165 is generally calculated as follows:

• Total amount invested (transferred to the scammer or scheme)
• Minus: Any amounts actually recovered or received back
• Minus: Any insurance reimbursement or other compensation received
• Equals: Your net deductible loss

For example, if you transferred $80,000 to a fraudulent crypto trading platform and received $5,000 back before the platform disappeared, your net loss is $75,000. That is the amount that may be deductible.

Adding Back Phantom Income You Already Paid Tax On

In Ponzi schemes and many fake investment platforms, the operator sends you account statements showing fictitious gains. If you reported those phantom gains as income on prior tax returns and paid tax on them, those tax payments are recoverable as part of your Section 165 loss calculation. Specifically, the IRS allows Ponzi victims using the safe harbor under Revenue Procedure 2009-20 to include prior phantom income in the net qualifying loss.

This can meaningfully increase your deductible amount. A victim who paid taxes on $20,000 of phantom income in addition to losing $80,000 of principal may have a qualifying loss closer to $100,000 before applying the safe harbor percentages.

The Reasonable Prospect of Recovery Rule

IRC 165 requires that a loss be “sustained” — meaning there is no reasonable prospect of recovery. If you have a pending lawsuit, a government receiver distributing funds, or a law enforcement proceeding that might result in asset recovery, you may need to defer part of your deduction until the recovery situation is resolved. In most crypto and online fraud cases, particularly those involving overseas perpetrators, recovery is extremely unlikely, and the loss can be treated as fully sustained.

However, if you receive a recovery in a future year after claiming the deduction, you will need to include that recovery as income in the year received — a process called the “tax benefit rule.” Your CPA can advise on how to handle this if it arises.

How the Deduction Reduces Your Tax Bill

The deduction reduces your taxable income dollar-for-dollar. The actual tax savings depends on your marginal tax rate:

• At a 22% federal marginal rate, a $75,000 deduction saves approximately $16,500 in federal tax
• At a 24% marginal rate, the same deduction saves approximately $18,000
• At a 32% marginal rate, savings would be approximately $24,000

These are estimates only — your actual savings will depend on your full income picture, filing status, other deductions, and state tax implications. A CPA will calculate the precise benefit for your situation.

What If the Loss Exceeds Your Income? Net Operating Loss

If your scam loss is larger than your total taxable income in the year the loss is claimed, you may generate a Net Operating Loss (NOL). Under current law, an NOL can be carried forward indefinitely to offset up to 80% of taxable income in future years. This means even a victim who had little income in the loss year can still recover tax value from the deduction over time.

State Tax Savings

Many states conform to federal tax law and allow a corresponding state income tax deduction. Depending on your state tax rate (which can range from 0% to over 13% in high-tax states), this can add meaningful additional savings on top of the federal deduction. Your CPA can determine your state’s conformity and calculate combined federal-plus-state savings.

Itemizing vs. Standard Deduction

Section 165(c)(2) losses are generally claimed as itemized deductions on Schedule A. If you currently take the standard deduction, a large scam loss deduction may make itemizing more beneficial. Your CPA will analyze both approaches and recommend the one that minimizes your total tax liability.

How to Get a Personalized Estimate

Every victim’s situation is different. The best way to understand your specific deduction amount and potential tax savings is to consult with a CPA who specializes in IRC Section 165 claims. With your tax returns, transfer records, and loss documentation in hand, a CPA can provide a clear picture of what you may be entitled to recover.
