@DanaB27 a follow-up question - since I was on F1 from start of 2021 until 9/30, I didn't have to pay medicare and FICA taxes. After switching to H1b on 10/01, those taxes started.
If I choose to elect myself and my wife as resident alien for the entire year, does my tax burden on medicare and FICA increase as well (essentially, would my medicare and FICA taxes be calculated from start of the year instead of 10/01)?
I didn't find any explanation of that anywhere else.
