Went I went with my proposal one of the first questions was " for which year did you file your last income tax" and then there were 3 sub questions: did you get a refund, are you owing , is there a copy available.  I think that this might matter as if you were getting a "big refund" it would be not fair to creditors since its an asset in hiding.  On the other hand if you owed a lot than tax men becomes a creditor as well.  I myself try never to mess with the tax man.
In my opinion it would be best to run a tax program and see where you stand. You can run the program without filing your taxes and than still ask your trustee what to do.  If you can afford it than future shop and best buy still might have 2010 in stock otherwise you can get it from the website. 

I am kind of facing an issue around taxes.  I have some outstanding corporation tax returns that the trustee suggested I ought to do before I declare bankruptcy.  So as I work on that, in the meantime my 2011 taxes will be ready to be done. 

I still have carry-forwards which the trustee informed me are erased with the bankruptcy.  I also have the RRSP contribution taxes to pay.  Since I've been on disability last year, this is a good year to add it to my tax return.  I think I will come out pretty even, no return, no tax due. 

But the trustee will only add the Minimum RRSP to my income to increase my return (it also keeps my income low so my HST returns and Child tax returns become higher... this will put me into the 21 month bankrupcy with surplus.)

I am going to have my personal return audited and submitted by a CGA this year so that it is accurate.  I am wondering if they can come back and say it was unfair me to do increase my income, to reduce the income in the future year?
