You can not put taxes in a bankruptcy. They WILL get your money, and there is no way you can stop it short of running to Mexico. They will take your bank accounts, take money out of your checks, even come by your house and take your stuff!
Basically If you owe the government there is no easy way out, and they will get their money. Refi your home, get a loan, take whatever means necessary to come up with the money.
