While a chapter 7 filing may not be right for you, an attorney may well recommend that you file a chapter 13 which is a payment plan. There are two portions which make up a payroll tax return, the trust fund which are the taxes withheld from the employees and the non-trust fund which are the taxes paid by the employer. In addition, if you were a corporate officer and personally assessed for the Trust Fund Recovery Penalty, don't look to the bankruptcy courts for help as that is never dischargeable. Also, even when taxes are dischargeable, it does not mean that you simply walk away from the entire tax bill. Exempt assets to which the court does not attach are still subject to a Notice of Federal Tax Lien if the IRS filed prior to the bankruptcy.
Exempt assets can include equity in a home, equity in a car and accounts receivable.
I recently had a case where the client was shocked that the IRS was still coming after her even though the bankruptcy discharged the taxes. We are currently negotiating with the IRS to see what they will accept to close out the case.
