Tax

K-1 (Schedule K-1)

Quick definition

Tax form issued by S-corps, partnerships, and LLCs to each owner showing their share of income, loss, deductions, and credits.

Schedule K-1 is the partnership/S-corp equivalent of a W-2, but instead of wages, it shows each owner's pass-through share of business income/loss for the year. Owners receive K-1s and report the amounts on their individual returns (Form 1040). K-1s often arrive late (March-September), forcing owners to extend their personal returns. Multi-state K-1s create state nexus for the owner in every state the entity does business.
