I'm desperate for help because I'm really going crazy and I don't know what else to do. My client also lives in Mexico and received their SSA-1042S, which states that their benefits were $12,551 and they had $3,202 withheld. They are not a resident for tax or immigration purposes. I'm filing the 1040-NR, but no tax exemption applies, and in the end, they still owe money. I've already submitted it about five times, and it keeps getting rejected. Each time, I've attached more annexes, and now I don't even know how to proceed. I have the Schedule OI, NEC, and 8339. Please guide me.
