Per IRS Instructions for Form 1065 U.S. Return of Partnership Income, page 2:

Partnership

A partnership is the relationship between two or more persons who join to carry on a trade or business, with each person contributing money, property, labor, or skill and each expecting to share in the profits and losses of the business whether or not a formal partnership agreement is made.

The term “partnership” includes a limited partnership, syndicate, group, pool, joint venture, or other unincorporated organization, through or by which any business, financial operation, or venture is carried on, that isn't, within the meaning of regulations under section 7701, a corporation, trust, estate, or sole proprietorship.

A joint undertaking merely to share expenses isn't a partnership. Mere co-ownership of property that is maintained and leased or rented isn't a partnership. However, if the co-owners provide services to the tenants, a partnership exists.
