If you’ve been contacted by the IRS about taxes that you owe, it’s unlikely that you’ll go to jail or that the IRS will take your stuff. The IRS has no interest in your stuff or in putting you in jail. They want money, right? Taking stuff and putting people in jail really only happens when the relationship has broken down to the point that there’s no communication between you and them. Or when there’s criminal activity involved (like fraud or evasion and such).
