(a) you need to tell more about the filer -- visa status, from which country, earning sources ( US and foreign ).
(b) in general , to be included on a return ( of a US person -- citizen/GreenCard / Resident for Tax purposes ), you need a TAX ID -- TIN ( SSN / ITIN /ATIN ).
(c) To request an ITIN , you need to file a form W-7 and all the documentation -- see --> About Form W-7, Application for IRS Individual Taxpayer Identification Number | Internal Revenue Ser...
(d) Depending on exact facts and circumstances, you can include the NRA person on your return ( using a dummy TIN, choose to file by mail, print, sign-date, replace dummy TIN with "N R A") then fill out the form W-7, include all the required documents and mail the whole package to the address shown on W-7 instructions. This should result in issuance of ITIN retroactively and the processing of the return.
The above is all general information. So for more specific answer , please consider answering my questions. Will circle back once I hear from you . If need be you can PM me
Is there more I can do for you ?
