Hi All,
I used my spouse's ITIN for FY22 return (due to a technical issue with IRS due to the SSN that was issued in 2021). For FY2023, I used the SSN and IRS accepted it without any issues.
Now I need to file an amendment for FY2022 but I am not sure if I should use the SSN or ITIN that was used originally in FY22. Any thoughts?
