As of 2020 my son's employer is withholding the correct, DC taxes.
As of this moment, my son has no intention on returning to CA. He's been renting an apartment in DC since mid 2018. He has no car but his DL and voting registration are still CA... Do you think it's critical for him to change it to DC?
What TT option should I use, to prepare 2019 return, in order to have access to Form 540NR?
I really appreciate all your advice! This DC vs CA residence is giving me a headache 🙂
