Final answer:
In the scenario where Kolt is a C corporation and Danni is a 30 percent owner, she is not allowed to deduct any of Kolt's business losses against her personal income regardless of her stock basis or hours worked.
Step-by-step explanation:
If Danni is a 30 percent owner of Kolt, which is organized as a C corporation, and it reported a $1,000,000 business loss, Danni will not be able to deduct any portion of this loss against her other income. This is due to the fact that C corporations are separate tax entities, and their losses are not passed through to their shareholders. Instead, the corporation itself carries the loss forward or back to offset against its own future or past taxable income. Regardless of Danni's basis in her Kolt stock or the number of hours she works for the company, these factors do not affect her ability to deduct Kolt's loss on her individual tax return.
