When trying to EFILE a T1 return, an "invalid character in free format area" error appears
Invalid character in free format area
There will be a 5 digit code associated with this message. The last 4 digits is the line # with invalid character. To jump to associated line, Goto Form Explorer > Select Line > type in the last 4 digit from the error > Press enter.
In most cases this error is due to:
1. 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.)
2. An incorrect Tax shelter identification number on form T2125.
