Partnerships file Form 1065 (PDF), U.S. Partnership Return of Income, to report income and expenses. The partnership passes the information to the individual partners on Schedule K-1, Form 1065. The partners report the information and pay any taxes due on Form 1040. Because partners are not employees of the partnership, no withholding is taken out of their distributions to pay the income and self-employment taxes on their Forms 1040. The partners may need to pay Estimated Tax Payments using Form 1040-ES.

Refer to Form 1065 Instructions, U.S. Partnership Return of Income and Publication 505, Tax Withholding and Estimated Tax for additional information.
