Ownership in multiple partnership and offset for losses

Hi

Another new one for me (usually had multiple schedule c's with 100% ownership)

Joe owns ABC LLP 50/50 with his son - no other employees. K-1 income was $250,000 for each partner.

Joe owns 3 other partnerships, 50% each and other 50% is unrelated. 2 partnerships had $50,000 k-1 losses each for Joe and 1 partnership has $25,000 of k-1 income for Joe.

If want to set up a DB plan for ABC LLP, what is the K-1 I can use?

Thank you for your comments.

Looks very straightforward to me.  You use the K-1 for ABC LLP.  You don't include comp from unrelated businesses.
