To prepare an electronic Form 1120S, 1120C, or 1120-F amended return, complete the steps below.


  • You should create a copy of the return before you enter amended information so that you have the original return available as well. To create a copy of the return, open the client’s return, choose File > Save As, enter a new client ID, and click Save.
  • Form 9325, Acknowledgement and General Information for Taxpayers Who File Returns Electronically, is based on the status of the client's return at the time Form 9325 is printed, not the status of the electronic file that was last accepted. Therefore, we recommend that you create a copy of the return before you enter amended information, so that the original client return is undisturbed.
  • You do not need to attach a copy of the original return to the amended return. If you choose to attach the original return, refer to Attaching Portable Document Format (PDF) file to electronic files for more information.
  1. Amend the client's tax data as necessary, making sure you adhere to the guidelines for entering data.
  2. In the folders block, click the Electronic Filing folder to open Screen ELF.
  3. Confirm that the File this return electronically field is marked.
  4. Enter a date in the Signature date field, if applicable.
  5. If you are not preparing an electronic amended return for a state return, enter X in the Suppress the creation of: State electronic file when only filing the federal return, extension or FinCEN Form 114 electronically field.


    • When you create the federal electronic file, UltraTax CS automatically creates the state electronic file, if appropriate. UltraTax CS generates a state FYI diagnostic message that indicates a state electronic file was created. You can file a paper return for the state and suppress the creation of the state electronic file. With the exception of Portable Document Format (PDF) attachments for electronic files, the IRS will not permit you to submit additional paperwork to the taxing authority.
    • For state electronic filing information, refer to the State Electronic Filing Guide on our website.
  6. To request an electronic funds withdrawal to pay a balance, complete the Electronic funds withdrawal for amended returns: Requested payment date field. Also, complete the bank information fields in Screen Bank in the General folder.
  7. Choose View > Diagnostics to review the diagnostic messages in the Federal Diagnostics window. Click any item displayed in the window to open the corresponding screen to address the diagnostic message. Verify that you have cleared all Critical and ELF Critical diagnostic messages and have reviewed the FYI diagnostic messages, and then close the Federal Diagnostics window.
  8. If desired, Thomson Reuters can send the client an email notification on your behalf when the federal and state (if applicable) returns are accepted. You must select this option in the client's return before you create the electronic file. For information about how to configure clients to have UltraTax CS send an acceptance email notification, see Configuring email notifications when electronically filed returns are accepted.
  9. By default, the government collation includes only the forms required to be submitted to the taxing authority when you file an electronic return. To modify these collations, choose Setup > 1120 Corporation to open the 1120 Product information dialog. Then, click the desired tab (Federal or state), and click the Tax Return button to modify the print collation for all electronic returns. For information about editing these collations, see Customizing the print collation for returns filed electronically. Thomson Reuters strongly recommends that you use the default collation. This will not affect which forms are included in the electronic file.
  10. Choose File > Print Returns or click the Print Print button button to open the Print Returns dialog.
  11. Mark the Government copy and the Create electronic file checkboxes.


    • To create the return or check the return for electronic filing errors without printing forms, mark only the Create electronic file checkbox under the Government copy checkbox in the Print Returns dialog.
      • To check for errors without creating the electronic file, click the Check E-File button.
      • To check for errors and create the electronic file, click the E-File button.
    • If you use a third-party application vendor to transmit returns, mark the Create electronic file (for 3rd Party) checkbox to create the electronic file. The third-party vendor is responsible for checking for errors.
  12. Click the Options button, and verify that the appropriate Federal and any state checkboxes are marked.

    Note: If you are creating only the FinCEN Form 114, Report of Foreign Bank and Financial Accounts (FBAR), clear the Federal and any state checkboxes, and mark the FinCEN Form 114 checkbox.

  13. To create electronic files for amended returns for multiple clients at the same time, click the Clients button and select the appropriate clients.
  14. Click the Preview button to view the amended return on screen, or click the Check E-File, Print, or E-File button. When you click the Preview, Print, Check E-File, or E-File button, UltraTax CS checks for errors in the electronic file.

    Note: You must click the Print or E-File button in the Print Returns dialog to create the electronic file for the amended return. Clicking the Print Preview button in the toolbar or clicking the Preview button in the Print Returns dialog does not generate the electronic file for the amended return.


  • When UltraTax CS creates electronic files for amended returns, the application automatically deletes any untransmitted electronic files for a client.
  • We do not charge a separate PRP fee for electronically filing amended returns.
  • If you use a third-party application vendor to transmit 1120 returns, UltraTax CS places the electronic file for the amended return in the location you specified in the Setup > User Preferences > File Locations tab. See Changing the location of electronic files for third-party application vendor transmissions for more information.
  • If you use a third-party application vendor as your transmitter, UltraTax CS creates the electronic file for the amended return without checking for errors when you print the return. The third-party application vendor checks for errors in these returns.
