“I filed bankruptcy in Sept.2006. I just heard from the trustee that I have to sign over my tax return ( if any) over to him, and that this would not be put towards the balance of my debt. I do not understand how he can take my refund legally? I live in Missouri.”

The trustee in bankruptcy takes control of all of the Debtor’s assets and can dispose of them as he sees fit. You could always withdraw your Petition. Part of the Petition referred to any money owed to you at the time of filing. This would include money owed to you from governmental agencies.
