Joint filers here - my wife and I live in NJ but she worked remotely for a company based in NY in 2021, where she reported to the work office less than one day a week.
For tax year 2021, NY reprocessed our state refund and gave us significantly less money because we could not obtain proof of in-office days from her previous employer, essentially paying double tax to both NJ and NY. Any advice or is this a lost cause?
