I have been incurring investment expense (margin interest) on my stock investments for the past several years but have never filed form 4952 because I always took the standard deduction. This year I realized that I should itemize and read somewhere that I could have filed 4952 in the past to carry forward the allowable investment expense even if I did not itemize in the past. Is it possible to complete and submit the 4952's of the past years along with this year's return to take credit for the investment expenses that I could carry forward from past years? Note that this does not impact my taxes for the past years so I would not be allowed to file amendments which are only allowed if it changes the tax amount.
Thanks
