My ex-wife, wife at the time filed taxes in 2012 prior to divorce in 2013 as Head of Household. We lived in a home I purchased prior to marriage, where the title was in my name only. She took tax documents addressed and sent to me in the mail (i.e., mortgage interest, property taxes, etc.) and used them for her itemized deductions. I am a CPA and law student, thus, I filed a Form 3949-A, an Information Referral to report fraud to the IRS. Also, I reported she understated income by $1,500 as she forged my signature on a check I received from my insurance company. I completed an affidavit to get the proceeds back. I reported this as tax fraud, as I needed these documents to complete my tax return to submit my request for federally funded financial aid. Could there be tax fraud charges?
