Thank you for this new question.
If you had a Sub S corporation
any profits or losses were filed on your personal taxes unless your corporation
elected to be taxed like a C-corp. If he has filed false returns, you have to file a complaint with the IRS and seek innocent spouse protection by filing the innocent spouse form.
Also, for any money he took from the business
that you were entitled to a share of, you would have to file a separate suit against him as a co-owner for breach of duty and seek to recover the money through the courts.
