Hi @DaveF1006 ,
Thanks for your reply. In this case, when I file form 4868 should we file it separately from my spouse estimating the tax due based on 1040NR married filing separately (since we're still nonresidents for tax purposes) or should we file form 4868 together estimating the tax due based on 1040 married filing jointly (since we'll claim residency after I pass substantial presence test in 2024 for first-year choice)? Thank you!
