What does a short sale entail regarding the taxpayer's ownership of the shares sold?

A short sale involves selling shares that a taxpayer does not own at the time of the sale. Instead, the taxpayer borrows the shares from another party in order to sell them, anticipating that the price will decline. The correct answer highlights the fact that the taxpayer does not need to deliver shares at the time the sale is executed.

In a short sale, the taxpayer's position is effectively that they have sold an asset they do not possess, with the intention of buying it back later at a lower price to return to the lender. This mechanism is central to the concept of short selling, where the immediate sale occurs without actual ownership being required. The obligation to deliver shares only arises later when the taxpayer closes the short position by purchasing shares back to return to the lender. Understanding this timing is crucial for comprehending how short sales operate within the realm of tax implications and market transactions.
