Which of the following is NOT considered an increase in an S corp shareholder's stock basis?

In the context of S corporations, a shareholder's stock basis is adjusted for various transactions that occur during the year. One of the key principles of S corporations is the concept that shareholders must adjust their basis in the corporation based on certain contributions and distributions.

When a shareholder receives money distributed from the corporation, this transaction does not increase their basis in the stock. Instead, it typically decreases their basis, as distributions represent a return of capital to the shareholder. Therefore, money distributed to the shareholder is not considered an increase but a decrease in the stock basis.

On the other hand, money contributed to the corporation by the shareholder, the adjusted basis in property contributed, and the shareholder's share of the corporation's annual income all represent increases to the basis. Contributions and income reflect the shareholder's investment and participation in the corporation’s profits, thereby enhancing their investment basis.

Thus, the correct answer identifies money distributed to the shareholder as the transaction that does not contribute to an increase in their stock basis, thereby demonstrating a fundamental understanding of how stock basis adjustments work in the context of S corporations.
