Electronically Filing Amended 2008 S Corporation Returns

Form 1120S

1. Before you amend the original return, we recommend that you make a backup copy of the return you will be amending.  Note: do not use Save As command to create copy.
2. Open the originally filed return.
3. On the S Corporation Information Worksheet go to Part V, Electronic Filing Information, and scroll down to the Electronic Filing of Amended Return section. Check the box next to "Check this box to file amended return electronically."
4. Open Form 1120S, p1-2. On page 1, line H, check Box 4 - Amended return to indicate an amended return. When you check this box, the program also checks the Amended K-1 box near the top of each Schedule K-1 Worksheet.
5. Make the necessary changes to the return.
6. Open and complete the Amended Return Explanation Statement (For Electronic Filing Only). If you do not have a state attached, skip to step 9.
7. If you have a state return attached, go to the state return and make any necessary state adjustments. If necessary, review the Tax Help and Government Instructions, or contact the state taxing authority for detailed information on amending the state return. (To indicate a state amended return, you may have to check a box on the main form or write Amended at the top of the form. You may also need to attach a statement of changes made to the return.)
   Note: The amended state return is NOT transmitted with the amended federal return. The amended state return cannot be filed electronically, it needs to be mailed to the state taxing authority.
8. If you went to the state return, go back to the federal return.
9. Attachments that were transmitted with the original federal return are NOT transmitted with the amended return. You must attach any PDF files that are applicable to the amended return.
10. Make sure the amended return passes Final Review.
11. Save the return.
12. When you're ready to e-file the amended return, go to the HomeBase EF Center.
13. Convert and transmit the client's amended 2008 corporation return the way that you converted and transmitted the client's original 2008 corporation return.
14. Check for acknowledgments the way that you checked for acknowledgments for non-amended returns.

Schedule K-1

If the amended return results in a change to income or the distribution of income or other information provided to a shareholder, an amended Schedule K-1 must also be filed and given to the shareholder. Ensure the Amended K-1 box is checked on each Schedule K-1.
