Thanks. That's helpful information. It may be that if self-employment tax is something in addition to regular income tax then yes, my liability is probably greater than I realized. I assumed the term "self-employment" tax was inclusive of everything I owe on that income. There's nothing additional on my K-1 (except the gross income of the partnership of which I only receive half as one of two partners). I will review the information at the links you provided.
