I was hoping I could fix it on my 2017 return. If I were to amend the open years, there would be no change in tax so amending would really be just an administrative correction. I am calculating my basis for capital gain using the correct amount of depreciation. The actual realization of the prior year losses would be in 2017 and since the property is being disposed, there is no future benefit to me. It seems logical but I need to figure out if it's allowable.
