A partnership generally is not a taxable entity. The income, gains, losses, deductions, and credits of a partnership are passed through to the partners based on each partner's distributive share of these items. For more information, see Publication 541.taxmap/pub17/p17-066.htm#en_us_publink1000171985
Although a partnership generally pays no tax, it must file an information return on Form 1065, U.S. Return of Partnership Income, and send Schedule K-1 (Form 1065) to each partner. In addition, the partnership will send each partner a copy of the Partner's Instructions for Schedule K-1 (Form 1065) to help each partner report his or her share of the partnership's income, deductions, credits, and tax preference items.
Keep Schedule K-1 (Form 1065) for your records. Do not attach it to your Form 1040.

If you and your spouse each materially participate as the only members of a jointly owned and operated business, and you file a joint return for the tax year, you can make a joint election to be treated as a qualified joint venture instead of a partnership. To make this election, you must divide all items of income, gain, loss, deduction, and credit attributable to the business between you and your spouse in accordance with your respective interests in the venture. Each of you must file a separate Schedule C or Schedule C-EZ (Form 1040).
