A partnership is a business entity in which partners own a portion of the business based upon a partnership agreement.  This agreement should always in be writing.  However, a partnership may be a verbal agreement.  Profits and losses and items with special tax treatment are allocated based upon ownership or policy.  The allocation also is determined by the agreement.  A partner does not have to be an individual, but can be another type of entity such as a business.  Profits can be considered income from self-employment, subject to Self Employment tax.
