What would a general tax percentage be on an income of $4200.00 from form 1099misc box 7 on form IT-203? I am a single mother of a three year old boy and my total income for the year including that 4200.00 is about 10,000. I know in the end I will not end up paying back because I will even out, but I just want to know the percentage that I will be taxed on that $4200.00. Please help!!
