Wire Fraud and Business Email Compromise: Your Tax Deduction Options

Wire fraud and Business Email Compromise (BEC) are among the most costly financial crimes affecting both individuals and businesses in the United States. According to the FBI, BEC alone costs American businesses and individuals billions of dollars annually. If you or your company has suffered a wire fraud loss, you may be entitled to a federal tax deduction under IRC Section 165 — and in some cases, a deduction that significantly offsets the financial blow.

What Is Business Email Compromise (BEC)?

Business Email Compromise is a sophisticated form of wire fraud in which criminals use legitimate-looking email accounts — often by hacking, spoofing, or impersonating email addresses — to trick employees, executives, or vendors into wiring money to fraudulent accounts. Common BEC scenarios include:

• CEO fraud: An email appearing to come from a company executive instructs an employee to wire funds immediately for a confidential acquisition or emergency
• Vendor impersonation: A trusted vendor’s email is compromised or spoofed, and updated wire instructions are sent, redirecting payment to a fraudster’s account
• Payroll diversion: HR or payroll staff receive emails that appear to be from employees requesting a bank account change, diverting salary payments
• Real estate wire fraud: Buyers or sellers in real estate transactions receive fraudulent wire instructions that divert closing funds to a criminal’s account

Fake Invoice Fraud

A related scheme involves fraudulent invoices sent to a company’s accounts payable department, often mimicking a real vendor’s letterhead and banking information. The company processes and pays what it believes is a legitimate invoice, but the funds go directly to the scammer. Fake invoice fraud is increasingly common and can victimize companies of all sizes.

Real Estate Wire Fraud: A Growing Crisis

Real estate transactions involve large wire transfers at closing, making them a prime target for wire fraud. Criminals monitor email communications between buyers, sellers, agents, and title companies, then inject fraudulent wire instructions at a critical moment. Victims may wire hundreds of thousands of dollars — often representing a down payment or the entire proceeds of a home sale — to a fraudulent account. In many cases, the funds are moved internationally within hours and are impossible to recall.

Tax Deduction Options Under IRC Section 165

Whether a wire fraud or BEC loss is deductible under federal tax law depends on the context — specifically, whether the loss occurred in a business or investment context or a purely personal one.

Business Context

If the fraud occurred in connection with a trade or business, the loss may be deductible under IRC Section 165(c)(1) as a business loss, or alternatively as an ordinary business expense under IRC Section 162. Business losses are generally deductible without the profit-motive requirement of Section 165(c)(2), making them somewhat easier to claim. The loss is reported on the business return and reduces business income.

Investment or Personal Context

If the fraud occurred in an investment or profit-motivated context — such as real estate wire fraud where funds were part of an investment property purchase, or an individual victimized through a fake business opportunity — IRC Section 165(c)(2) may apply. The profit-motive requirement is generally met when the transaction was entered into with the expectation of financial return.

Insurance Offsets

Many businesses carry cyber liability insurance or crime insurance that may cover BEC or wire fraud losses. Under IRC 165, your deductible loss is reduced by any insurance reimbursement you receive or have a reasonable prospect of receiving. If you have submitted an insurance claim, you should work with your CPA to properly account for the insurance offset in your loss calculation. The amount not covered by insurance remains potentially deductible.

It is important not to simply assume insurance will cover the full loss — many policies have sublimits or exclusions for social engineering fraud, and actual reimbursement may be partial or denied.

Documentation for Wire Fraud Tax Claims

Strong documentation is essential for any wire fraud tax deduction. You should preserve:

• The fraudulent email instructions and all related correspondence
• Bank wire confirmations and transfer records
• FBI IC3 and local law enforcement reports
• Any correspondence with your bank regarding recall attempts
• Insurance claim records and adjuster communications
• Evidence of the fraudulent scheme (fake invoices, spoofed email headers, etc.)

Acting Quickly Matters

Wire fraud victims should act immediately to report the fraud to their bank and law enforcement — there is a narrow window in which wire recall may be possible. From a tax perspective, the loss is generally deductible in the year it is sustained, meaning when recovery becomes clearly unlikely. A CPA who understands both the tax and financial dimensions of wire fraud can help you navigate both the immediate response and the long-term tax strategy.
