So I sent Letter of Explanation over regular mail to Franchise Tax Board. I called them and they claim not to have yet received and/or scanned it. And instead suggested to Fax it.
However, I could not find fax number on their website so I tried to contact them over chat to find if it is ok to fax Tax Return. Now I got different answer that it is not ok to electronically send it because this is for previous years.
Contradicting information!
Has anyone had successful experience with sending amended Tax Returns to Franchise Tax Board?
This is for General Partnership form 565.
