McCaughn v. Ludington

Background

A private investor bought corporate stock before March 1, 1913, paying $32,500. The stock’s market value on March 1, 1913 was $37,050. The investor sold the shares in 1919 for $3,866.91. On his tax return he claimed a loss measured from the March 1, 1913 market value, which was larger than the loss measured from his purchase price. The tax collector disallowed the larger deduction and assessed additional tax. The investor paid under protest and sued to recover the tax.

Reasoning

The Court applied an earlier decision that measures deductible loss by the actual economic loss in the transaction. The key question was whether the deductible loss could be computed from the March 1, 1913 market value or only from what the investor actually paid. The Court held the loss must be the actual difference between purchase and sale prices. Because the investor’s true loss was $28,633.09 (purchase minus sale), not the larger figure based on the March 1, 1913 value, the larger deduction was improper.

Real world impact

The decision means taxpayers cannot claim larger deductions by using a historical market value date instead of their actual purchase price. For investors who bought property before the statutory cutoff date, deductible losses on sale will be limited to purchase-to-sale losses, which may increase tax owed in similar situations. The ruling affirms the lower court’s judgment and rejects the appeals court’s contrary ruling.

Dissents or concurrances

Two Justices dissented. Their views were noted but did not change the Court’s final holding limiting deductible loss to the actual transaction loss.
