Can I file bankruptcy and include delinquent property taxes from 2010 and 2011?

Yes you can file chapter 13 and have the taxes included in your plan

Yes, but you will have to pay the taxes at some point.

If you file a Chapter 13, yes, you can pay the delinquent taxes through that. But, you can also just try to work out a payment plan with the taxing authorities. They are usually pretty easy to work with. And, that would be much cheaper than bankruptcy.

Unfortunately, property taxes cannot be discharged in bankruptcy. The county has the authority to foreclose on your property for any delinquent taxes. The best thing to do is to open negotiations with them: Perhaps they will allow you time to come up with a payment plan proposal. They usually will do all they can, within their statutory deadlines, to work with you, especially since you took possession of this property when the taxes were already owed (so you were not the one who ran up this tax bill, essentially). I recommend talking to them and working out a payment plan. Bankruptcy will not help you at all.

The taxes would still be a lien on the property. Pay them or you may be eligible for a chapter 13 which would give you a plan of reorganization to pay them.
