I have a partnership interest in a PTP for 2024. The rules for basis tracking and passive loss limitation seem clear to me. However, the extent to which this is "at risk" for the purposes of having to file form 6198 is not clear. Of course as a "stock" there is a potential for the whole interest to become worthless. However, on my K-1, there are only non-recourse liabilities listed in section K1 which makes me wonder if I should be doing form 6198 at all. Can you help clarify this situation for me?
