I am filing Married but separate from my husband, I only worked one month out of the year and he is going to claim our son... So I am just curious how much I would get back if total of wages was around 600 dollars... I had no federal withheld but had social secruity and medicare withheld.. and the state tax was less than five dollars... can I get an estimate of about how much I would receive back?

You will get ALL federal and state taxes withheld back.
