My soon-to-be ex husband else claimed me on his taxes without agreement and now I can not file my return. What should I do? And how do I find out if he claimed my children?

How do I get my income tax back from my ex

An individual may not file a joint tax return without the consent of the marital partner.
Filing a joint tax return without the consent of the marital partner is a crime.
Similarly, signing your name on the return without your consent is considered forgery, which is also a crime.
If a joint return was filed without your consent, the IRS will automatically deem the non-consensual joint tax return to be fraudulent.
If the IRS decides that your spouse filed the joint return intentionally and without your consent, he may face hefty financial penalties.
In addition, if the IRS decides that your spouse filed the joint return intentionally and without your consent, your spouse may have to go to jail.
If the non-consensual return is filed during a divorce proceeding, you may be entitled to relief from the family court in Oklahoma City or other court that is handling your case.

This answer side steps the practice of “tacit consent” which may arise from a history of filing joint returns and not actually filing a separate return for the year in question.
