What is a Schedule K-1?

K-1 is issued by partnerships, S-corps, estates, and trusts to report each owner/beneficiary share of income, deductions, and credits. Each partner/shareholder reports K-1 items on their personal return.

How is partnership income allocated?

According to the partnership agreement. The agreement specifies each partner distributive share, which must have substantial economic effect. Absent agreement, allocated per ownership percentage.

Does K-1 income affect basis?

Yes. K-1 income increases outside basis; K-1 losses and distributions decrease it. You cannot deduct losses exceeding your basis. Track basis carefully to avoid unexpected tax.

Is K-1 income subject to self-employment tax?

Partnership K-1 ordinary income for general partners is subject to SE tax. Limited partners and S-corp shareholders generally are not subject to SE tax on their allocated share.

Partnership K-1s are due with the partnership return: March 15 (or September 15 with extension). S-corp K-1s are similarly due March 15.
