"Error 56: Invalid date..." for 1120 return with prior-year data


🔍 Error 56: Invalid date... for 1120 return with prior-year data

Due to e-file regulations, the date field on the NOL carryover worksheet changed from a four-digit year field (YYYY) to a month and year field (MM/YYYY). Also, no punctuation is allowed in this or other similar fields of returns that will be e-filed.

⚠️ Before You Begin

Make sure you update the date value to match the e-file format:

  • Use MM/YYYY instead of YYYY
  • Do not include punctuation in this or other similar fields

📊 Step-by-Step Guide

Step 1: Acknowledge the error message

Use this when you see the Error 56 message.

Click OK in this message box.

Step 2: Update the date in the Review Entry box

Use this when the date field still shows a four-digit year.

Then replace the four-digit year shown in the Review Entry box with the month and year of the end of your client's tax year, such as 12/2009 for a 2009 calendar-year filer.

Step 3: Remove punctuation from the field

Use this when you included punctuation in the date or similar fields.

Remove any punctuation you may have included in this or other fields.
