I filed for taxes before like 3 years ago, I have been working at a new job and was of the books , but recently I was told I needed a social security because IRS Department fined my boss since he had almost everybody of the books, here is my question can my Itin number be used for this puspose, I reside in New York so prety much everybody has employees working for them of the books, I don't qualify for a social security number because of my legal status... so is the Itin number valid to file for taxes in this case??
