Is it required to file 1040X and send with 8606 form for each year it is missed?
I have the same problem and one of the IRS help on line advise to file 1040X along with 8606 form.
Thanks for your suggestion
A 1040X is only required if you are changing from a deductible or non-deductible contribution or visa-versa that would require either paying additional tax or getting a refund. Simply reporting a missed 8606 that should have been included with the original tax return does not require a 1040X because you are not amending anything, you are just supplying an original form that was missed.
And yes, a separate 8606 for the tax year that is was required must be filed for each year.
8606 form are only required if:
1) You make a new non-deductible Traditional IRA contribution.
2) You take a distribution from a IRA that has a after-tax "basis".
3) You make a conversion of a retirement account to a Roth IRA
Past year forms for each here can be downloaded form the IRS site:
If none of those occurred, then the last filed 8606 remains in effect
