If you can, make a payment of the tax now. This will avoid any more interest and penalties if you lose. If you win, IRS will refund the money with interest. If you cannot pay - or don't want to pay - you can wait till the case is resolved, but you will have to pay additional interest and penalties if you lose. Ideally, you should get a tax attorney to help you through this process.
