It really depends on how much is owed in back taxes to the IRS. However, you can be assured that you will be required to pay back everything you owe in addition to interest compounded for every year that you failed to pay. Not only will a lot of time be wasted in interviews with the IRS, but bank records and corporate minutes will have to be furnished. In addition, if whatever is owed cannot be paid via corporate assets, personal assets are not immune.
