Am I responsible for back taxes or since I filed bankruptcy am I cleared of all debt including the taxes?

You need to talk to your bankruptcy attorney. These issues are far too complicated to look for answers in this forum.

Taxes are only dischargeable in bankruptcy if they meet a variety of criteria, one of which is that they must be 3 YEARS OLD measured from the due date of the tax return. If your taxes are for a year AFTER 2008, they would NOT have been discharged in your bankruptcy. Your question, however, seems to have something to do with tax owed on account of the debt cancelled in the foreclosure of your prior home. If you filed bankruptcy before the foreclosure was concluded, and the mortgage debt was discharge, you should not have any tax liability. See Section 108(b) of the Internal Revenue Code.

Income Taxes are (possibly) dischargeable in bankruptcy if they are for taxes that became due for tax years greater than three (3) years ago; the tax return was filed at least two (2) years ago; the taxes were "assessed at least 240 days ago, and there was no indication that there was fraud or evasion of taxes. Having stated the broad general rules, let me note that there are many, many, many ways that taxes can become non-dischargeable in the event certain things happened or did not happen since the tax liability was assessed. This is not something to attempt on your own, nor should an inexperienced Bankruptcy attorney rely on this broad outline. See a Bankruptcy attorney with sufficient experience to determine if any of the tax liability is dischargeable.

Property taxes are an in rem taxes and run with the land. Basically, they are paid upon sale of the property.
