There are so many different kinds of taxes and the law is so complicated, that the best answer is: sometimes. Bankruptcy is about the only law more powerful than the IRS. Usually, only income taxes can be discharged. Sales or withholding tax cannot.
In order for income taxes to be dischargeable, you must have:
1. filed your return on time, and
2. the date you filed your return must be more than 3 years ago. (April 15 is due date but can be April 16 or 18 because of weekends some years)
If your return was filed late, you need only wait two years after it was filed to have your income taxes eligible for discharge. If you didn't file a return, your income taxes are not eligible for discharge.
If your income taxes do not fall under the above time periods, or if you did not file a return, you may be eligible to force a repayment plan on the IRS, if you have sufficient regular income, by proposing a Chapter 13 Debt Repayment Plan. In a Chapter 13, you can pay past due income taxes over as long as 5 years, with no further interest or penalty, in most cases, and the IRS cannot take collection action during the Chapter 13 Plan. Of course, you must pay any future income taxes on time, and you must file any tax returns not previously filed, as a condition of having your Chapter 13 approved.
There are many other kinds of taxes, and special rules apply to all of them. I make no guarantee that any tax is dischargeable, because of the complexity of the rules, and the policy of not making most taxes dischargeable. We list them on the petition, however, notify the IRS and proper governmental entities, and then if the tax is not discharged, it is possible to work out a repayment plan based on your bankruptcy budget which we prepare.
