Federal taxes are considered "priority taxes" if they cannot be discharged, although they can be paid off through a Chapter 13 plan. If the taxes were assessed more than 3 years ago, they are treated as "non-priority debt" and will get the same treatment as all other unsecured debt, meaning they will only get paid to the extent that you have the ability to pay them beyond the priority debts. The remaining non-priority taxes will be discharged at the end of your Chapter 13 plan if you complete it. Assuming you are filing the Chapter 13 in good faith, your plan must include a way to cure the arrearage on your mortgage AND it must pay off your priority taxes at the statutory interest rate (which is 3 percent for IRS.) If you aren't able to demonstrate that you have the means to handle these obligations, your case will be dismissed and you will not be able to keep your house out of foreclosure. The judge can bar you from filing another Chapter 13 for a period of time if s/he determines your filing was in bad faith, so you should not take this filing lightly. Very few people are successful in a Chapter 13 without legal help, even lawyers who think they can do it themselves.
