Other forms that partnerships may need to file include:

Filing the Form

Due date and extension options

  • Form 1065 is due on March 15th of each year for calendar year partnerships, with the option to request an extension until September 15th. If the due date falls on a weekend or holiday, the deadline is extended to the next business day.
  • To request an extension, partnerships must file Form 7004, Application for Automatic Extension of Time to File Certain Business Income Tax, Information, and Other Returns, by the original due date of the tax return.

Partnerships have the option to file their tax returns both electronically using the IRS's e-file system or by submitting a paper return to the pertinent address that is specified in the instructions. Electronic filing is highly recommended as it has the ability to reduce the likelihood of mistakes and speed up the processing time. 

Consequences of late or incorrect filing

If a partnership does not submit Form 1065 or files it late, they may be subject to penalties. One of these penalties is a fine of $200 per partner each month for a period of up to a year. In the event that the partnership has an outstanding tax liability, further charges such as interest and penalties may be levied.

The Internal Revenue Service may seek further information or conduct an audit if the partnership submits a return that is either erroneous or incomplete. Inaccurate reporting may also result in disciplinary action being taken.
