High-earning freelancers often receive multiple K-1s from business partnerships, investment partnerships, and real estate entities. Each requires separate reporting and tracking.

Partnership B (investment): $25,000 portfolio income (not subject to SE tax)
Partnership C (real estate): $20,000 rental income (passive activity)
