There are various business entities that are required to file a federal partnership return. This information will primarily concern limited liability companies. A domestic LLC that has not filed form 8832 (requesting to be considered a corporation) will automatically be considered a partnership if there are two or more members.
All domestic partnerships are required to file a 1065 unless it neither receives income nor incurs any expenditures treated as deductions or credits for federal income tax purposes.
A partnership that uses the calendar year must file the 1065 information return on or before April 15. Partnerships with noncalendar fiscal years must file on or before the 15th day of the fourth month following the end of their fiscal year.
