Hi Nelsona
Hope you are doing well. I filed my taxes per your guidance use the PRO FORMA 1040 rate on form 1040NR. I just got a letter today from IRS saying basically that I owe them money. Basically they disregarded the PRO FORM 1040 value line 11 which was used to calculate the tax rate inputted on line 42 of the Real 1040NR. What do you advise that I do? Please help. They are saying I owe a good $1850
