Final answer:
All partners in a general partnership, which includes Jose, Mahlon, and Eric, can potentially deduct their share of partnership losses on their personal tax returns, provided they meet specific criteria related to their basis and at-risk investment in the partnership.
Step-by-step explanation:
The ability of Jose, Mahlon, and Eric to deduct their share of the partnership loss in New Communications Partnership, which is a general partnership, depends on several factors including their involvement in the business and the tax regulations pertaining to partnership losses. In general, all partners in a general partnership can potentially deduct their share of the business's losses on their personal income tax returns. However, there are limitations based on factors such as the level of active participation, basis in the partnership, and at-risk limitations. Assuming all three partners meet the necessary criteria to deduct losses (for instance, they have sufficient basis and are at risk for the investment), all of them would be eligible to deduct their respective share of the loss from their individual tax returns.
