"Invalid character in free format area" error when trying to EFILE a T1 return

When trying to EFILE a T1 return, an Invalid character in free format area error displays.

Cause of the error

Usually this error is due to:

• A negative amount on a line where it should be positive amount (if the box must have negative amount, return needs to be paper filed).
• An incorrect Tax shelter identification number on form T2125.
• Invalid characters (for example, % ) $ @ ( # &) have been entered into a free format area, such as a taxpayer's personal information in the Personal Information page.

There will be a 5-digit code associated with this message. The last 4 digits are the line number with invalid character.

To jump to the associated line:

1. Navigate to Goto in the menu bar and select Line Number View. The Form Explorer opens in line number view.
2. Enter the last 4 digits from the error.
3. Select on your keyboard.
