Final answer:
Darin will have $10,000 of the partnership loss allocated to him as he owns 25% of the partnership. However, he can only deduct up to his at-risk amount of $5,000 in the current year, regardless of his tax basis.
Step-by-step explanation:
The student is asking how much of the partnership loss will be allocated to Darin, a 25% owner, and how much he will be able to deduct on his current year tax return, given his tax basis and at-risk amount in the partnership.
Darin's share of the partnership's $40,000 loss would be 25%, which amounts to $10,000.
However, Darin can only deduct losses up to the at-risk amount, which is $5,000. Therefore, the loss allocated to Darin is $10,000, but he will only be able to deduct $5,000 in the current year.
