Financial Glossary
Schedule K-1 is the information form a partnership, S corporation, or estate/trust issues to each owner or beneficiary to report their share of the entity's income, losses, deductions, and credits. The entity does not pay income tax itself; instead, each recipient takes the K-1 figures onto their own personal return. There are different K-1 versions tied to the entity's return, such as Form 1065 for partnerships and Form 1120-S for S corporations.
Real estate investors holding property in partnerships, campground LLCs taxed as partnerships, and founders with S-corp ownership all receive K-1s that they cannot file their personal returns without. K-1s often arrive late and contain pass-through items like depreciation, passive losses, and distributions that affect how much tax the owner actually owes. Misreading a K-1 or filing before it arrives is a common cause of amended returns.
A K-1 is how pass-through income reaches the individual taxpayer, so every recipient needs theirs in hand and read correctly before filing. Treat it as a required input, not an optional document.
