from ITIN to social security number

mytaxesdone — Wed, 18 Feb 2026 16:28:57 GMT

A spouse just received a social security number. Previous income tax returns were filed under an ITIN number. Because of using an ITIN number, certain credits couldn't be claimed. Can past income tax returns be amended to update the social security number and get certain credits not obtained before?

Is this possible?

Please advise...

@mytaxesdone , very generally No. I say this because many of the credits that are limited/ qualified by SSN , generally use words like " must be issued" by filing date or during the year in question and "at least One spouse , if filing jointly". Thus the exact facts and circumstances and the credits involved are important.

If you need a more specific answer ( i.e. tuned to your personal situation ), please provide more details as to filing status, immigration/visa status, particular credit and of course the country you are from ( in case there is any treaty considerations ).

Will circle back once I hear from you --yes ?

You cannot filet retroactively to get an earned income tax credit or child tax credit, which may be the primary reasons for you to do so. You would have to have had a social security number by the due date of the tax return to be eligible for those credits.
