Hi Critter and Carl, I made the same mistake as Nellie, except I am an LLC, so wonder if your advice applies to me as well. I entered the wrong EIN # (off by one digit) on my LLC's Schedule C attached to my personal 1040. I am a single member LLC with no employees and all taxes were paid under my SSN. I only made this error on my Schedule C's (for several years) and the IRS never contacted me about the error. Does your advice hold that it doesn't need to be fixed? Should I just not enter my EIN on my next returns?
