I'm yet to file my 2019 tax return. Till 2018 tax return i used to file my tax with my SSN and wife ITIN - Married filing jointly. My wife got her SSN recently and I've sent a letter last week to IRS to rescind her ITIN and update SSN in her records.
Since IRS hasn't acknowledged the rescind letter, so I'd like to know should I file 2019 tax return with her SSN or ITIN? Will my returns be impacted because IRS didn't acknowledge yet.
Any help would be really appreciated!!!
