Get your taxes done using TurboTax

Assuming that you ( a US citizen)  are residing  in Canada, to be able to file  US tax return as MFJ ( Married Filing Jointly), you can either  (a) download  form W-7 from the IRS, fill it out, attach all the documents  asked for   and mail this in to the IRS  OR  (b) do nothing now, when you file your 2019 return, file as MFJ, print , sign ( both you and your spouse), fill out form W-7 , include all the attachments required, add a note -- signed by both of you -- stating that you both would like to have your spouse treated as a tax resident of the USA AND  send the whole shebang to the IRS by mail.  The former would result in issuance of ITIN perhaps before the  filing date ( ?? ) while the latter will generally result in issuance of an ITIN for your spouse retrospectively i.e. for the year 2019 tax year.

I still suggest  that you try and visit the IRS section as also the consular section   of the nearest  US consulate --- perhaps they can certify the documents ( passports , marriage cert etc.  ) needed for an ITIN for your spouse.  They will definitely have the latest on the subject.

Good Luck
