H1B visa holder, file as single head of household or married?
I'm currently on an H-1B visa and spouse on H-4 therefore she doesn't have a SSN and no job.
Is it better to have my W4 and eventually yearly tax as single, head of household? If I do this can I still enter a 1 on line C on the W-4 for spouse?
Or the second option should I apply for a TIN and file as married filing jointly.
Please keep in mind that we have 3 kids so I'm trying to get the best tax rate and the right one as well.
Thanks in advance for the advice.
