My wife did not have a SSN at the time of filing our 2008 federal tax return, and therefore we were not eligible to get the recovery rebate credit. We used her ITIN at that time. She recently got her SSN and we would like to claim the credit.
- Can we send an amendment (1040x) with her new SSN to claim the credit?
- If this will work, do we need to attach copies of her ITIN and new SSN?
Thanks.
