I would certainly need more details before I could form an opinion, yes it is possible to sue an accountant for malpractice however you have two issues, one it would appear that the claim maybe time barred by the statute of limitations, which is very short and professional malpractice cases, and the other is that you should be reviewed and been aware of the contents of your various returns before you signed and submitted them.
