I am here in US on H1 and my wife on H4. I think I am a resident alien.
What should be the score for Head of Household, I support my wife financially i.e. she is my dependent. What would be the score on line H for my case on form W4 ?
Thanks,

If you complete substantial presence test (SPT), you can file resident tax return. Read about SPT: Your U.S. Tax Return: Substantial Presence Test

You are not Head of Household. Your spouse is never your dependent. You can file joint return as residents if you meet SPT. Read about Head of Household: Your U.S. Tax Return: Filing Status: Head of Household
