Naysha Oquendo v. Comm'r of Internal Revenue

Plain English (For Everyone)

Imagine you bought some stock and later sold it for less than you paid, hoping to claim a tax break. To get that break, you need to prove how much you originally paid for the stock. In this case, the person couldn't prove their original cost, so the tax break was denied. It's like trying to get a refund without a receipt – you need proof of purchase.

For Legal Practitioners

The Sixth Circuit affirmed the Tax Court's denial of a capital loss deduction due to the taxpayer's failure to establish cost basis. This case underscores the critical importance of meticulous record-keeping for substantiating deductions, particularly capital losses. Practitioners should advise clients that mere reliance on prior filings or constructive ownership arguments are insufficient to meet the burden of proof when challenged by the IRS.

For Law Students

This case tests the requirements for claiming a capital loss deduction under IRC § 165(f) and § 1011, specifically the necessity of proving cost basis. It reinforces the taxpayer's burden of proof in tax court. Students should note that constructive ownership rules do not obviate the need for direct evidence of basis when claiming a loss.

Newsroom Summary

The Sixth Circuit ruled that a taxpayer cannot claim a capital loss deduction without proving the original cost of their stock. This decision highlights the strict documentation requirements for tax deductions, impacting individuals who sell investments at a loss.

Constitutional Issues

Whether the taxpayer's activities constitute a 'trade or business' for purposes of the Qualified Business Income (QBI) deduction under 26 U.S.C. § 199A.

Rule Statements

"To qualify for the deduction, the income must be from a qualified trade or business."

"An activity qualifies as a trade or business if it is carried on by the taxpayer with regularity and continuity and if the taxpayer's primary purpose in carrying on the activity is the realization of a profit."

Scenario: You sold stock for less than you bought it for and want to claim a capital loss on your taxes.

Your Rights: You have the right to claim a capital loss deduction if you can prove the cost basis of the stock and that you sold it for less than that basis.

What To Do: Keep meticulous records of all stock purchases, including the date, number of shares, and purchase price. If you've lost records, try to obtain duplicates from your broker or financial institution. Be prepared to provide this documentation to the IRS if audited.

Is it legal to deduct a capital loss from stock if I can't prove how much I paid for it?

No. You cannot legally deduct a capital loss from stock if you cannot prove its cost basis. The IRS requires documentation to substantiate the original purchase price of the stock to allow for a capital loss deduction.

This ruling applies to the Sixth Circuit Court of Appeals, but the underlying tax principle regarding the necessity of proving cost basis is a federal requirement applicable nationwide.

For Individual Taxpayers

Individuals who have sold stock at a loss must ensure they have clear documentation of their original purchase price (cost basis). Failure to do so, even if the loss is real, can result in the disallowance of the deduction upon IRS audit.

For Tax Professionals

This case serves as a reminder to diligently advise clients on the importance of maintaining robust records for all investment transactions. It reinforces that arguments based on prior filings or constructive ownership may not suffice when the IRS challenges the basis of a deduction.
