Answer: Alano's taxable income increases by $300,000.
Step-by-step explanation:
Constructive dividends are paid to a shareholder and classified in such a way that they are not to be seen as taxable dividends.
If during auditing however, the IRS determines that it was indeed a taxable dividend, it becomes a constructive dividend.
Constructive dividends are taxable by definition so Alano's taxable income increases by the amount of dividend of $300,000.
