You may receive a Schedule K-1 if you are a partner or shareholder of a business that passes income, losses, deductions, and credits on to individual partners or shareholders. The partnership itself typically doesn’t pay income tax on the shareholders’ behalf, instead the profits and losses get passed through to the individual partners. This is called pass-through income.

A Schedule K-1 is prepared and given to each member of a partnership or shareholder of an S corp showing their individual share of the profits and losses. Partnerships and S Corps are required to provide each partner or shareholder a copy of their Schedule K-1 by the 15th day of the third month after the end of their tax year, which may be different from the calendar year depending on the accounting method they use. If you are expecting a Schedule K-1 and have not received one, you should check with your partnership or S corp to see if and when they will issue a Schedule K-1.
