If you need to make changes to your Partnership Form 1065 U.S. Return of Partnership Income return after it has been filed, you may need to file an amended return. The IRS supports both paper-filing and e-filing for amended returns.

To complete the amendment process:

1. Locate a copy of your originally-filed return. If you didn’t print or save your return when you e-filed, you will need to obtain a copy from the IRS or your state tax agency.
2. Review your returns and determine what corrections you need to make.
3. From within your TaxAct 1065 return, modify, add, or delete the information that needs amending. Make note (on paper or in a computer document that you create) of each item you are changing and the reason for each change (you will need these notes to complete the amendment).
4. From within your TaxAct 1065 return (Online or Desktop), click Filing, then click Amend Federal Return (on smaller devices, click in the top left corner of your screen, then click Filing).
5. Continue with the interview process until you reach the screen titled Amended Federal Return - Filing Form 1065X, click Print Form 1065X or E-file Form 1065X.

• Paper-Filing (Print):
  If you clicked Print Form 1065X, when you click Continue, you will be prompted to print Form 1065X Amended Return or Administrative Adjustment Request (AAR) and will be provided with the mailing address for the form.
  
  If the corrected amount involves an item of income, deduction, or credit, attach the appropriate schedule, statement, or form to Form 1065X. Include the entity’s name and EIN on any attachments. If the attachments needed to support the corrected amount include copies of forms or schedules from previously filed tax returns, write at the top of each previously filed form or schedule: "Copy Only—Do Not Process."
  
  
• E-Filing:
  If you clicked E-file Form 1065X, when you click Continue, you will need to click E-File My Return and continue through the filing steps until the return has been successfully submitted.

See the IRS Instructions for Form 1065X for additional information.

Corrected Schedule K-1s (if applicable): If the income, deductions, credits, or other information provided to any partner has changed, then new Schedule K-1(s) must be filed with the amended return and corrected copies sent to the affected partners.

Note. The IRS only mandates electronic filing for partnerships with more than 100 partners, that are required to use Form 1065-B (instead of Form 1065). Only partnerships that are mandated to e-file their return would be required to e-file an amended return. The IRS has a Guidance for Amended Partnership Returns webpage that provides additional information.

Note that any link in the information above is updated each year automatically and will take you to the most recent version of the webpage or document at the time it is accessed.
