I married last January and had to update my W2 information from single to married. I wasn’t sure how it should be changed to so would you please advise below looks reasonable for married status? I updated federal status to married but I am really not sure if I have to change it to state status as well. Thanks! Tax Withholding Information

맞벌이를 하시면 두분다 married에 no exemption(0)을 넣으시는 것이 안전합니다.
단 혼자서 버시면 married 2를 하시면 될것같은데요.
