So per the latest rule from IRS -
"To establish a joint name line, a Taxpayer Identification Number (TIN) is needed for both spouses. Acceptable TINS include a Social Security Number (SSN), Individual Taxpayer Identification Number (ITIN) or Internal Revenue Service Number (IRSN), and should be established on or before the due date of the return they are filing".
Does this mean if I apply MFS this year, than my spouse will need to have SSN/ITIN prior to April 15 if I have to make an amendment in the future?
Or is it okay to file MFS this year, and get ITIN/SSN later (when she arrives to the US) and we can amend?
Just a bit worried with the quote posted as it seems like it is stating you can only amend from MFS to MFJ if you had a SSN/ITIN prior to the original due date.
